2023 U.S. Department of Energy HVAC Regional Efficiency Standards

2023 U.S. Department of Energy HVAC Regional Efficiency Standards Map

Effective November 25, 2023, the U.S. Department of Energy (DOE) has amended the test procedures for central air conditioners and heat pumps that are required for certification of compliance with applicable energy conservation standards starting January 1, 2023. The map shown above indicates the three separate regions defined by the DOE. Within each region there are minimum efficiency standards listed for each type of equipment. While it is the responsibility of manufacturers to comply and only produce products that meet these standards, it is important for homeowners and installers to understand and verify your equipment selections meet the minimum standard for the DOE region your state is in.

The changes made by the DOE are two-fold. Not only did the minimum efficiency ratings change as they do year-to-year, the entire set of test procedures changed as well to represent improvements that more accurately reflect field conditions. You will see this notated with a “2” at the end of each efficiency standard. Below is the translation:

      • Energy Efficiency Ratio (EER) [Btu/Wh] >> EER2
      • Seasonal Energy Efficiency Ratio (SEER) [Btu/Wh] >> SEER2
      • Heating Seasonal Performance Factor (HSPF) [Btu/Wh] >> HSPF2

INFLATION REDUCTION ACT INCENTIVES 2022 - 2032

The Inflation Reduction Act (IRA) that became enrolled law on August 16, 2022 provides several incentives for homeowners, building owners, and contractors for installing or upgrading heating and cooling systems to higher energy efficient systems in an effort to reduce greenhouse gas emissions.

In addition to a previously enacted nonbusiness energy property tax credit, there are three major components of the new law that taxpayers may take advantage of. The new benefits will not be available until January 1, 2023 and the US Department of Energy still needs to sort out how the application process will work and how funds will be distributed to each State office. Combining these rebate programs is not allowed and there are several limitations for each to be aware of. Below is a brief description of each:

  1. “High-Efficiency Electric Home Rebate Program” provides cash rebates for new equipment installations and upgrades with household income level limitations.
  2. “Home Owner Managing Energy Savings (HOMES) Rebate Program” provides greater incentives for whole-house projects with household income level limitations.
  3. “Energy Efficient Home Improvement Tax Credit (Section 25C)” provides tax credits for installed equipment that exceeds CEE’s highest tier (not the advanced tier) and has no income level limitations.
      1. Additionally there is a Home Energy Audit tax credit for up to $150 for a taxpayer’s principal residence
  4. “Nonbusiness energy property” tax credit, a previous law under Section 25C, is extended to December 31, 2032 for property placed in service after December 31, 2021.

High-Efficiency Electric Home Rebate Program

The most applicable program to most homeowners is the “High-Efficiency Electric Home Rebate Program” (HEEH). The rebate caps are as follows:

  • Program Qualification Dates: To be determined; the policy provisions to implement HEEHRA are not yet in place. Federal agencies including the IRS, EPA, and DOE will create the rules and regulations for distributing the money but the individual states will be directly involved in implementing the program.
  • Maximum combined rebate is $14,000
  • Amount of rebate per qualified household:
    • Energy Star certified appliance upgrades under a qualified electrification project:
      • Up to $8,000 for heat pump for space heating and cooling
    • Non-appliance upgrades under a qualified electrification project:
      • Up to $4,000 for an electric load service center upgrade
      • Up to $1,600 for insulation, air sealing, and ventilation
      • Up to $2,500 for electrical wiring
      • Purchased of an appliance / non-appliance under a qualified electrification project

Limitations are primarily based on income level favoring low- and moderate-income households. This is based on the area median income (AMI) for where the property is located and can be found by entering an address at this website or this calculator, which will inform the user of what the 80% and 100% area median income is for that area. To calculate the 150% threshold, simply multiply the 100% value by 1.5. That will provide the maximum household income that would qualify for the rebate program. The amount of the rebate is graduated by the income level as follows:

  • For a low- or moderate-income household:
    • If your household income is below 80% of the area median income, then 100% of the system purchase price qualifies for the rebate.
    • If your household income is between 80% and 150% of the area median income, then 50% of the system purchase price qualifies for the rebate.
    • If your household income is greater than 150% of the area median income, then you are not eligible for the rebate.
  • For an individual or entity that owns a multifamily building not less than 50 percent of the residents of which are low- or moderate-income households:
    • 50% of the cost of the qualified electrification project for a multi-family building is not less than 50% of the residents that are households with an annual income between 80% and 150% of the area median income.
    • 100% of the cost of the qualified electrification project for a multifamily building is not less than 50% of the residents that are households with an annual income less than 80% of the area median income.
  • For a governmental, commercial, or nonprofit entity, as determined by the Secretary, carrying out a qualified electrification project on behalf of an entity described as:
    • 50% of the cost of the qualified electrification project for a household where the eligible entity is working and the annual income is between 80% and 150% of the area median income.
    • 100% of the cost of the qualified electrification project for a household where the eligible entity is working and the annual income is less than 80% of the area median income.

For heating and cooling systems, a “qualified electrification projects” means:

  • Purchase and installation of:
    • An electric heat pump for space heating and cooling
    • An electric load service center
    • Insulation
    • Air sealing and materials to improve ventilation
    • Electric wiring
  • The project may be:
    • Part of new construction
    • Replaces a non-electric appliance (e.g. gas, oil, or coal)
    • A first-time purchase with respect to the appliance
  • Appliance, system, equipment, infrastructure, component, or other related item must be certified under the Energy Star program.
  • The project is carried out at, or relating to, a single-family home or multifamily building, as applicable and defined by the Secretary.

Home Owner Managing Energy Savings (HOMES) Rebate Program

The “HOMES Rebate Program” provides rebates for whole-house energy saving retrofits that started on or after August 16, 2022 and are completed by September 30, 2031. Similar to the “High-Efficiency Electric Home Rebate Program”, the amount of the rebate is determined by the household income level in relation to the area median income. This program bases the rebate on either modeled or measured energy savings. The rebate caps are as follows:

For single-family homeowners:

  • The lesser of either $2,000 or 50% of the project cost for a retrofit that achieves modeled energy system savings between 20% and 35%.
  • The lesser of either $4,000 or 50% of the project cost for a retrofit that achieves modeled energy system savings over 35%.
  • For measured energy savings:
    • Must achieve energy savings at or above 15% and either:
      • A payment rate per kilowatt hour saved, or kilowatt hour-equivalent saved, equal to $2,000 for a 20% reduction of energy use for the average home in the State; OR
      • 50% of the project cost

For multi-family building owners:

  • $2,000 per dwelling unit with a maximum of $200,000 per multi-family building for a retrofit that achieves modeled energy system savings between 20% and 35%.
  • $4,000 per dwelling unit with a maximum of $400,000 per multi-family building for a retrofit that achieves modeled energy system savings greater than 35%.
  • For measured energy savings:
    • Must achieve energy savings at or above 15% and either:
      • A payment rate per kilowatt hour saved, or kilowatt hour-equivalent saved, equal to $2,000 for a 20% reduction of energy use per dwelling unit for the average multi-family building in the State; OR
      • 50% of the project cost

For single-family or multi-family owners with homes/dwelling units occupied by a low- or moderate-income household (greater than 50% for multi-family):

  • The lesser of either $4,000 per single-family home or dwelling unit or 80% of the project cost for a retrofit that achieves modeled energy system savings between 20% and 35%.
  • The lesser of either $8,000 per single-family home or dwelling unit or 80% of the project cost for a retrofit that achieves modeled energy system savings over 35%.
  • For measured energy savings:
    • Must achieve energy savings at or above 15% and either:
      • A payment rate per kilowatt hour saved, or kilowatt hour-equivalent saved, equal to $2,000 for a 20% reduction of energy use per single-family home or dwelling unit, as applicable, for the average single-family home or multi-family building in the State; OR
      • 80% of the project cost

Energy Efficient Home Improvement Tax Credit (Section 25C)

The Energy Efficient Home Improvement Tax Credit is an existing tax credit for installing heating and cooling systems that exceed the Energy Star requirements and installed at the taxpayer’s principal residence. This tax credit is available for all income levels. The current program under Section 25C was extended to December 31, 2032 for property placed in service after December 31, 2021. The updated credit program applies to property placed in service after December 31,
2022. Any property placed after December 31, 2024 will require the manufacturer to supply a serial number. The credits will be available until 2032.

  • For individuals, a tax credit within the given tax year may occur equal to 30% of the sum of:
    • The amount paid or incurred by the taxpayer for qualified energy efficiency improvements installed during such taxable year,
    • The amount of the residential energy property expenditures paid or incurred by the taxpayer during such taxable year, and
    • The amount paid or incurred by the taxpayer during the taxable year for home energy audits.
  • Tax Credit equal to 30% of costs incurred up to:
    • $1,200 annually including:
      • $600 for eligible air conditioners
      • $600 for eligible furnaces
      • $600 for eligible A natural gas, propane, or oil furnace or hot water boiler
    • $2,000 annually for purchase of electric heat pumps
    • Up to $150 for Home Energy Audit for a taxpayer’s principal residence the provides the following:
      • Identifies the most significant and cost-effective energy efficiency improvements with respect to such dwelling unit, including an estimate of the energy and cost savings with respect to each such improvement
      • Conducted and prepared by a home energy auditor that meets the certification or other requirements specified by the Secretary in regulations or other guidance (as prescribed by the Secretary not later than 365 days after the date of the enactment of this subsection).
  • Income requirements:
    • None.
  • Combining programs:
    • Cannot use with the “High-Efficiency Electric Home Rebate Program”
    • May be eligible to combine with local or utility rebate programs.

Nonbusiness Energy Property Tax Credit (previously enacted program)

The previous program that is now replaced by the Inflation Reduction Act of 2022 and is now effective to December 31, 2032 for property placed in service after December 31, 2021. While waiting for the new incentives to go into effect beginning January 1, 2023, households are able to receive up to a $300 tax credit now for the current tax year (2022). The total of current and previous years credits after 2005 for this program, including those for energy efficiency improvements, high efficiency furnace and air conditioner cannot exceed $500 (lifetime limitation).

The tax credit for an individual, for the tax year the item was purchased, is calculated as the sum of 10% of the amount paid or incurred by the taxpayer for qualified energy efficiency improvements installed AND the amount of residential energy property expenditures paid or incurred by the taxpayer during such a taxable year.

A “qualified energy property” can be:

  • An electric heat pump that achieves the highest efficiency tier established by the Consortium for Energy Efficiency, as in effect on January 1, 2009 – 15 SEER or higher for split systems and 14 SEER for packaged unit heat pumps.
  • A central air conditioner that achieves the highest efficiency tier established by the Consortium for Energy Efficiency, as in effect on January 1, 2009.
  • A qualified natural gas, propane, or oil furnace or hot water boiler that achieves an annual fuel utilization efficiency rate of 95 or higher, OR
  • An advanced main circulating fan that is used in a natural gas, propane, or oil furnace that has an annual electricity use of no more than 2% of the total annual energy use of the furnace (as determined by the standard Department of Energy test procedures).

This tax credit does not apply to new construction or rental properties. Must be the taxpayer’s principal residence.

 

Applying For Tax Credits or Rebates

For the tax credits, you’d claim them on your federal income tax returns. We’re not yet sure which form you’ll need to complete, but in previous years, IRS Form 5695 was used for a similar residential energy credits program. A good tax preparer will know what to use, and programs like TurboTax often guide you in a way that makes it easy to claim relevant tax credits. The rebate programs will vary from state to state, and are still to be determined. They could potentially be implemented through utility companies, or through state-run agencies. There is a line in the bill that encourages the Department of Energy (DOE) and state programs to work together to make the rebates accessible at the point of sale—building it into the out-of-pocket cost for consumers.

A Quick Guide to Mini-Split Air Handlers

A Quick Guide to Mini-Split Air Handlers

 

If you’re shopping for a ductless mini-split, you already know these small-but-mighty HVAC systems provide a comfort solution for many home applications–a room addition, a climate-controlled workshop or other flex space, or a bedroom that is always too hot or too cold. Once you have determined the size (capacity) of the mini-split system you need (check out our Ductless Mini-Split System Selector or reach out to one of our HVAC experts for help), it’s time to think about what type of air handler(s) will best suit your needs.

The Top 5 Air Handler Types

When it comes to air handlers (the indoor portion of the mini-split system), there are five main types to choose from. Your choice of air handler will impact performance, aesthetics, and budget. 

1) The Wall Mount

The standard wall-mounted air handler is the most common type and most popular option for our customers. It is typically the easiest to install, the most efficient, and generally the most economical choice. 

wall-mounted air handler mounted in room

These units are designed to be mounted about six feet above the floor and at least six inches below the ceiling. They are most commonly (and most easily) installed on an exterior wall but can also be mounted on an interior wall. Wall-mounted air handlers have a sleek profile and modern look. These units draw air in through vents at the top and release conditioned air directly into your space through louvers at the bottom.

2) The Ceiling Cassette

The ceiling cassette has proved to be our second most popular type of air handler, despite its higher upfront cost. Its popularity is likely due to its discreet appearance, which resembles a traditional ducted vent cover or grille.

For those who either don’t have the wall space to accommodate a wall-mounted unit or want the body of the air handler to be hidden from view, the ceiling cassette provides an ideal solution. Install one of these units in a drop ceiling or nestle it in-between the ceiling joists. 

Ceiling cassettes are high-efficiency units on par with wall mounts. If installed in the center of a room, a ceiling cassette can better mix the air due to air disbursement in four directions.

3) The Low Wall

Low wall air handlers mount on the wall at or just above floor level. They have a low profile (slimmer than some wall mount styles), and some customers prefer the look of low wall units over the standard wall mount.

The image above shows how airflow in a low wall unit reverses direction in heating and cooling modes. In heating mode, warm air enters the room from the bottom of the unit for better heat distribution. In cooling mode, conditioned air blows from the top.

Low wall air handlers make a great choice when a higher wall placement is not an option, for example, when the ceiling height is lower than 7½ feet. A low wall unit may be the best option for an A-frame house, a finished attic, or a living area above the garage.

4) The Wall/Ceiling or Floor/Ceiling

Floor/ceiling (also called wall/ceiling) air handlers are similar to the low wall style in that they can be mounted to the wall at or near floor level. This makes them another good option for short wall applications. However, wall/ceiling units are more versatile because they can be alternately suspended from the ceiling in a horizontal position.

wall/ceiling style air handler mounted two ways

Floor/ceiling units are a good choice for those wanting to free up floor space or those with no wall space to spare. Note that, unlike the ceiling cassette, the body of the wall/ceiling air handler will hang down approximately 9 inches from the ceiling, making it visible in the space. When aesthetics is not a primary concern, the tradeoff is a lower price on these units compared to the ceiling cassette.  

5) The Concealed Duct

The last type of air handler for your ductless mini-split system is the concealed duct. But wait a minute–a ducted ductless mini-split? You heard us right. The concealed or hidden duct mini-split is an overlooked style that offers several advantages. But first, let’s take a look at how these units work.

concealed duct air handler installed above ceiling

Concealed duct air handlers can be installed above the ceiling, in an attic; below the floor, in a basement or crawl space; or behind a soffit. As such, they provide maximum flexibility for challenging applications. Attach flexible ducting, and the unit can heat and cool multiple rooms and provide a more even distribution of air within the home. 

Those with more than one space to heat or cool can save money with a concealed duct system. Because it utilizes just one air handler, it will cost less than a multi-zone system with two or three air handlers. 

Lastly, a concealed duct system is the most hidden of all air handler types; you will not see it at all in your space. The only visible part of the system is the air vent covers, which are the typical size and type found in traditional ducted HVAC systems.

How to Choose the Right Mini-Split for your Garage

How to Choose the Right Mini-Split for your Garage

Ductless mini-split systems are a popular choice for garage conversions. Turning your garage into a livable space–a workshop, game room, gym, office, or home theater–can be a great way to get the most out of your home.

When converting your garage, one of the most important decisions is the type of equipment you will use to condition the space. Unfortunately, running new ductwork can be expensive and may require replacing your existing HVAC equipment.

Mini-splits are an ideal solution when it comes to this type of application, and they offer several advantages over traditional HVAC:

  • Typically cheaper than modifying or replacing existing ducted equipment
  • Straightforward installation (90-100% can be DIY if you are handy)
  • Year-round, energy-efficient heating and cooling 
  • Whisper-quiet operation
  • Independent climate control
  • WiFi connectivity and smartphone / smart home hub compatible

A mini-split can be customized to your specific garage and how you intend to use the space. Independent climate control is perfect for a flex space like this, as you may not want to heat or cool the garage if unoccupied for long periods. WiFi connectivity allows you to control the system directly from your phone: turn the unit off while you’re away, and turn it on before you arrive home so that your space will be ready when you are.

6 Sizing Considerations for your Garage 

The HVAC experts at Alpine recommend considering the following important factors when choosing the right size and type of mini-split for your garage:

  1. Square Footage
  2. Ceiling Height
  3. Insulation
  4. Air Escape through Gaps and Doors
  5. The Climate in Your Region 
  6. How Will You Use Your Repurposed Garage?

Square Footage

The first step in finding the right mini-split system for your garage is to know your square footage. Garages vary in size, with typical 1, 2, and 3-car garages being approximately 20’ x 12’ (240 square feet), 20’ x 20’ (400 square feet), and 20’ x 30’ (600 square feet), respectively. If we look solely at square footage, a simple mini-split sizing chart might suggest the following sizes for average 1, 2, and 3-car garages: 9,000 BTU, 12,000 BTU, and 18,000 BTU. However, in many cases, these units would not perform to expectations because the unique attributes of a garage were not taken into account. To avoid undersizing your system, read on.

Ceiling Height

The average ceiling height of a garage is 8-9 feet, though some are higher and may be vaulted. The extra air volume will require additional heating and cooling power. To adjust your square footage to take a high ceiling into account, use the following formula:

 

  • 9 feet or under is normal
  • For 10 feet, multiply the square footage by 1.1
  • For 11 feet, multiply the square footage by 1.2
  • For 12 feet, multiply the square footage by 1.3
  • For 13 feet, multiply the square footage by 1.4
  • For 14 feet, multiply the square footage by 1.5
  • For 15 feet, multiply the square footage by 1.6

 

Insulation

Attached garages are not well-insulated compared to the rest of your house. Typically, the shared wall between the garage and the home is the only wall that contains insulation. With three out of four sides of the space uninsulated, it will take more power to maintain your desired temperature in the garage than in other rooms of your home. Detached garages usually lack insulation on all sides.

 

We recommend insulating your garage as much as is practical because it can save you from the higher upfront cost of upsizing your mini-split system and the ongoing energy cost of conditioning a poorly insulated space. A cheap and easy garage door insulation kit, which ranges from $50 to $100, will provide at least some protection from temperature swings. Lack of insulation, however, is not a deal-breaker. Upsizing your system by at least one size should provide ample power to maintain your desired temperature within the space.

Air Escape through Gaps and Doors

Another significant difference between garages and the living spaces of your home is the large doors that open directly to the outdoors. If you plan to use the space with the door(s) partially or fully open, or if the door(s) will open and close with regularity, you’ll want to consider a more powerful unit that can overcome the loss of conditioned air. 

Even if you plan to keep the garage door(s) closed most of the time, keep in mind that the perimeter may not be tightly sealed, leaving gaps where air can escape. Check for gaps along the left and right sides of the door, and make sure that the weather stripping makes full contact with the floor along the bottom edge of the door.

The Climate in Your Region

If you live in a moderate climate without prolonged temperature extremes, then a standard mini-split system should be adequate to condition your garage. However, if your region experiences periods of sub-freezing or sub-zero temperatures, then a 4 or 5 Series Blueridge mini-split will keep you comfortable during the coldest months. These sophisticated units can provide heat down to -22℉ outside. In extremely hot climates, these same units will help keep the sweat off your brow while you work or play.

How Will You Use Your Repurposed Garage?

Two key factors that may affect your system size are: what you plan to do in your space and how often you will use it. Consider the following:

  • Will you be generating heat in the same area you’re trying to cool?

For instance, will you use any equipment that creates a significant amount of heat? Or will you regularly hold gatherings of more than 4-5 people in your space? If yes, we recommend upsizing your system to provide adequate cooling. Let’s imagine the following two scenarios:

  1. You have a garage that normally needs 12000 BTUs of cooling. However, you host a weekly game night with 15 friends. When all 15 friends are in your space, they add approximately 400 BTUs of heat per person, per hour. (That’s 15 people x 400 BTUs = 6000 BTUs of heat generated!) Therefore, if you want to stay cool on game night, you’ll need to size up to an 18000 BTU system.

  1. Your workshop usually needs 18000 BTUs of cooling, but you have a small kiln that adds 5000 BTUs of heat per hour to your space. If you use your kiln during the summer months, then you would need 23000 BTUs of cooling power (18000 + 5000) to stay cool in your space.

 

  • Will you use the space frequently or occasionally?

Mini-split systems have a well-deserved reputation for efficient heating and cooling. They achieve maximum efficiency when maintaining a set temperature over time, on a low-and-slow mode. If you plan to use your space often and keep your mini-split running in this high-efficiency mode, then there is no need to increase the size of your system. 

However, if you will only use your garage space occasionally and plan to turn the system off when the room is not in use, then you may want to size up. Here’s why. As soon as your system turns off, the temperature and humidity of the room will change as conditioned air escapes and unconditioned air enters. When it’s time again to use the space, you’ll want it to feel comfortable right away. The mini-split will work extra hard to achieve your desired temperature (many units have a “turbo” mode for this very purpose), but it may not happen as quickly as you would like. We recommend going up a size  to rapidly heat and cool your space.

Air Handler Type and Location

Mini-split systems consist of two units–the outdoor condenser or heat pump and the indoor air handler. Air handlers come in various styles to suit both practical and aesthetic purposes. With a garage space, the choice comes down to functionality. Where is the best place to put your air handler, based on the layout of your room? In some cases, your placement needs may determine the type of air handler best suited to your space. 

The Wall-Mounted Air Handler 

The most popular type, and our top recommendation for a garage application, is the wall-mounted air handler. These mount directly on a wall 6 feet or more above the floor and at least 6 inches below the ceiling. 

wall-mounted air handler mounted in room

As long as you have the wall space, wall-mounted units are typically the easiest type to install. They mount on exterior or interior walls, and you can even position them close to where you will be within the room to further enhance your comfort level. Standard wall-mount air handlers range from 9000-36000 BTUs of heating and cooling and can cover most garages.

The Wall/Ceiling Air Handler

Not much wall space to spare? Wall/Ceiling units provide flexibility during the installation process, allowing floor-level placement or suspension from the ceiling.

These units offer between 18000-60000 BTUs of heating and cooling capacity, so they are also an excellent choice for oversized garages or when you have upsized your system to account for lack of insulation or other factors, discussed above.

The Ceiling Cassette

What if your wall space is at a premium, and you have a lower ceiling height? Or perhaps you’re looking for a more discrete unit. 

ceiling cassette style air handler

Although the priciest style of air handler, the ceiling cassette mounts flush with the drywall and has louvers on all four sides to distribute air evenly within your space. The inner workings of the air handler are cleverly concealed above the ceiling, in-between the joists. No wonder it is our second most popular style!

Dual-Zone Mini-Split System (2 Air Handlers)

For oversized or L-shaped garages, you might consider two air-handling units to cover the space. Our multi-zone systems pair one outdoor heat pump with two or more air handlers (same or different styles) to more efficiently mix the air in a larger space.

Thinking about installing a Blueridge ductless mini-split? Many of our customers choose to do the majority (90%) of the installation themselves and then hire a pro for the final start-up. Our DIY mini-splits allow customers to complete 100% of the installation on their own. 

 

In this article, Alpine’s HVAC experts explain the process of installing a mini-split system with wall-mounted air handler in four easy steps:

Step 1: Mounting a Ductless Mini-Split

Step 1: Mount

  • Outside: Install the condenser on a pad or bracket and in a convenient location.
  • Inside: Attach the included mounting plate on the wall where you want to install the air handler.
  • Using a hole saw, drill through your wall at a slight downward angle, adjacent to the lower right-hand side of the mounting plate. Insert wall sleeve, if desired.
  • Hang the indoor unit on the mounting plate while running the refrigerant lines, wiring, and drain tubing through the hole to the outside.

Step 2: Connecting Line Sets

Step 2: Connect

  • Using a torque wrench, secure the refrigerant lines to the connectors on the indoor unit and then the outdoor unit.
  • Connect the wiring between indoor and outdoor units. Make sure to match each color of wire to the corresponding terminal.
  • Discharge the condensate line away from the wall and to the outside.

Step 3: Electrical Work

Step 3: Electrical

We recommend hiring an electrician for this portion of the job if you are not trained to work with high voltage electricity.

  • Turn off power at the breaker box.
  • Depending on your particular model, run 220- or 110-volt power from a dedicated circuit on your breaker panel to a disconnect box located near the outdoor unit. 
  • Install an electrical whip (weatherproof power wiring) connecting the disconnect box to the outdoor unit.
  • Turn the power back on at breaker box.

Step 4: Start Up

Step 4: Start-Up

A. Conventional Mini-Split: Hire a Pro

Your HVAC contractor will:

  • Do a pressure test to check for leaks
  • Pull a vacuum on the refrigerant lines
  • Release the refrigerant from the condenser into the system
  • Add refrigerant if the refrigerant lines are longer than the factory precharge in the system
  • Startup and test the system

 

B. DIY Mini-Split: Self Start-Up

  • Release the refrigerant from the outdoor unit into the system using an Allen wrench.
  • Check for leaks: Use a spray bottle with soapy water where the line sets connect. 
    • If there are leaks, retighten the line set connections to the proper torque.
  • Turn on the system.
