How Much Does HVAC Installation Cost?
- Installation of a new HVAC system in a 1000 square foot home with a combination of a new central air conditioner unit, a new gas furnace, and the ductwork labor for your home, you could expect to pay in between $6,000 to $12,000 in total HVAC installation costs. If this is new construction, on a 1,200 to 2,400 sq. ft home it can cost between $1,200 to $4,200 extra in ductwork installation alone. Use our cost calculator above for accurate local pricing.
What Factors Affect Cost?
Installation costs will change depending on a few factors that are specific to your home and location. Here are the main things that your air conditioning contractor will asses in order to give you the most exact price quote for your replacement HVAC system:
- Local climate conditions
- Current ductwork conditions
- Home age and construction
- HVAC unit features such as size, brand, and energy efficiency (SEER)
1. Local Climate Conditions
Depending on where in the US your home is located, the local region’s climate can change dramatically. A home located in the South would need an AC unit with a size capable of cooling your home due to high temperature Summers. A home in the Northern part of the US would need a much larger heating capacity as well which will affect costs. See the chart below for the average costs of a central AC unit only by TONS.
|Central Air Conditioner Size||AC Unit BTU||AC Unit Only|
|1.5 Tons||18,000 BTU||$2,000|
|2 Tons||24,000 BTU||$2,620|
|2.5 Tons||30000 BTU||$2,895|
|3 Tons||36000 BTU||$2,920|
|3.5 Tons||42000 BTU||$3,550|
|4 Tons||48000 BTU||$3,650|
|5 Tons||60000 BTU||$3,690|
2. Do You Need New Ductwork?
If you are replacing your current air conditioning system, it’s safe to assume that you already have ductwork installed. Ductwork delivers the conditioned air from your HVAC system throughout your home through vents often found in your home’s attic and However, with time ductwork can lose its’ efficiency or may need to be altered to work with your new AC system. New ductwork installation can tack on an additional cost anywhere from $1,200 to $4,200 depending on the level of complexity to install or alter. Plan to add a few days of labor to your HVAC replacement project if you do need ductwork replacement.
3. Home Age and Construction
The ability to cool and heat your home at maximum efficiency will depend a lot on how well insulated your home is currently and the size of your home. A 2500 square foot home will need a much larger AC unit than a smaller home, which will impact installation costs. Also a house with energy efficient windows that are well insulated and sealed well with no cracks for air flow will require far less AC capacity to keep temperatures comfortable. Other factors that can affect this could be the insulation elsewhere such as the foundation, roof, attics, basements, flooring, and more.
4. HVAC Unit Features
A local and trusted HVAC service installer will be able to tell you best what features you may need or want for your home’s system. Higher priced AC unit costs will come with higher energy efficiency levels known as the SEER rating. The size of the unit will also make a different in AC unit prices. The HVAC brand you choose will also impact total installation costs. Higher end central AC units will cost more upfront. However, better brands usually come with a longer lifespan, better warranties, and smarter technology built in to fully control your home’s temperature.
Average HVAC System Costs
The average costs for different HVAC installation types vary depending on brand, SEER rating, and much more. A local heating and cooling contractor near you will be able to give you an exact price quote or see our full guide on the cost to install a central air conditioner unit. However, you can assume you will pay somewhere in the area below for average HVAC systems costs:
- Central Air Conditioner Installation: $3,500 to $7,600
- Ductless AC Installation: $3,000 to $5,000
- Heat Pump Installation: $5,000 to $6,500
- Gas Furnace Installation: $4,000 to $6,500
|HVAC Installation Costs||Low Cost||High Cost|
|Central Air Conditioner||$3,500||$7,600|
|Geothermal Heat Pumps||$20,000||$27,000|
Ready to start
There may also be some AC installation costs that are not included in the initial HVAC estimate but you will want to factor in just in case. These are the things you should ask the air conditioning contractor if the following costs are included in the initial quote they’re providing. Be sure to always ask these questions.
- If a permit is required from your local city or county building department. The unit will also require an inspection by a representative of the building department to ensure the system is up to code.
- If you live in an older home that has asbestos or lead paint, there may be an additional cost to test, remove, or replace the material.
- If any of the following requires additional work involved with the installation process – plumbing, electrical work, removal of an existing system, installing the HVAC system at a new location, modifying the framing or surfacing of the home, or bringing any systems up to code – it will also factor into the cost estimate for your home’s new HVAC installation.
Evaluating Price Quotes for HVAC Installation
There are a quite a few factors to consider when determining what could affect the cost of a new HVAC system installation price quote. Some factors may cause your initial cost estimate to be higher or lower. It is advised to get at least four local price quotes from different qualified HVAC contractors. Let Modernize help connect you to reliable local contractors.
High Priced AC Installations:
- HVAC installation and replacements can vary drastically in price. These disparities could be due to the type of HVAC unit—how quiet an air conditioning system is, for example. We encourage homeowners to research their desired HVAC system and make sure it is the best suited for their homes and needs.
- HVAC units can also vary in total cost depending on hardware other than the main units themselves. The increasingly popular smart thermostat is often paired with a new residential HVAC unit, which could cost as little as $30 or as much as $300.
- High-end heating and cooling contractors will likely have more equipment and overhead, which may be seen in your price quote.
- HVAC unit warranties will also impact your total installation costs. Most HVAC installers offer manufacturer’s warranties that protect you from faulty system equipment. Some might offer additional guarantees for the total HVAC installation as well, covering potential damage to your roof (if applicable.)
- Research and be aware of potential hidden HVAC costs— like needing permits and potential fines for your installation. Your heating and cooling quote should include a proper breakdown of how local or federal regulation applies to you and what your HVAC contractor will or will not do in that regard.
- For example, if your installed HVAC unit’s Seasonal Energy Efficiency Ratio (SEER) rating is lower than 13, the Department of Energy might flag your HVAC contractor for selling it.
- An HVAC system having an average SEER rating of 16 could mean saving upward of $400 annually in comparison to other lower efficiency options.Expect an analysis of what your bills should look like after your new HVAC installation, and how you should expect these heating and cooling energy costs to change in upcoming years.
Low Priced AC Installations:
- If an HVAC contractor does not have proper insurance, they will often provide a lower bid. This may leave the homeowner responsible for HVAC laborer injuries or damages that occur. We recommend that homeowners always select a licensed HVAC contractor for their heating and cooling replacement projects.
- If a contractor doesn’t have a solid grasp of local policies or applicable local, regional, and federal incentives—like the ones found at the Database of State Incentives for Renewables and Efficiency, they may leave that to you and subsequently lower their fees since they have less paperwork to worry about. While a contractor may charge you for help navigating the bureaucracy of air conditioning regulation, a good contractor will assure your energy compliance in your area and maximize your return on investment utilizing expertise you may lack.
- Extremely low bidders may also be desperate for a new HVAC job leads, which is never a reassuring sign. Be sure to always vet your HVAC contractor before hiring for the job.
For any bid you receive you should always double check your final HVAC installation quotes for possible pricing errors. Errors can happen when trying to determine your full HVAC system installation costs. Communicate any and all questions and concerns with your air conditioning installer before you sign off on any contracts.
