How Much Does It Cost To Install a New AC Unit?

October 27, 2022

Whether you are thinking about buying a new one or replacing your failing air conditioner, it is important to learn which cooling system type you need and how much it will cost to install it. 

Installing a new air conditioning system will usually cost you around $6,000 to $8,000, with many factors that help determine the price. For example, the unit type, size, energy efficiency rating, and even the layout of your home are all factors to help calculate an accurate cost for replacing your AC unit. 

Factors Affecting Air Conditioner Installation Costs

Initial Evaluation

Pre-installation evaluation will depend on the air conditioner you want to install and the arrangement of your house. Consult an HVAC professional service to assess your home so you can find the air conditioner options that best suit your household’s needs. (Remember, every purchase at includes an evaluation of your home prior to installation – to make sure that you order the perfect equipment for your home.)

With the help of the HVAC pro, you can determine what system size should be installed and how well your house is insulated. They can assess how well your rooms can retain heat, then make recommendations for which size system has the capacity to cool the areas in your house.

Initial evaluation by HVAC professionals can help you foresee risks and setbacks that could have proven costly later on. A site visit is essential for the success of your AC installation because that is where the HVAC specialists will confirm that factors such as home size, unit type, etc. are a good fit for your home and budget.


Central air conditioning systems can be complicated and require a professional to install. While relying on professional installation from a licensed contractor increases overall AC replacement costs, it is required to maintain the manufacturer warranties (and when you shop with – all warranties (parts and workmanship) are valid!)

The overall cost of installation may vary depending on the type of system, electrical, thermostat, ductwork, and insulation needs. 

Luckily, when you shop with – we’ve pre-negotiated your installation fees. So the price you see, is the price you pay!



Pick a new AC unit online that best fits your home, and based on HVAC experts’ professional recommendations. Typically, central air conditioning systems fall under two categories – split or package units.

  • Package System – A Split System is made up of two units: an outside unit referred to as the condenser that you normally see on the side of your home, and an inside unit usually referred to as the air handler that is normally located in a closet or sometimes in the attic.
  • Split System – A Packaged System contains both the condenser and the air handler in one package. These units normally sit on the roof but sometimes are located on the ground.

Air Conditioning Costs According to Size

The “size” of an air conditioning system does not necessarily mean the unit’s physical dimensions. It usually indicates its power or cooling capacity, usually measured in BTUs or British Thermal Units. This measurement system usually converts 12,000 BTU to one ton. Please refer below for the corresponding average costs according to size:

  • 1.5-ton goes for around $3,500 to $4,500
  • 2-ton goes for around $3,100 to $5,100
  • 3-ton goes for around $4,400 to $6,400
  • 4-ton goes for around $5,200 to $7,200
  • 5-ton goes for around $7,400 to $9,800
  • 14 SEER goes for around $6,000 to $8,000
  • 16 SEER goes for around $7,000 to $9,000
  • 18 SEER goes for around $9,000 to $12,000
  • 20 SEER starts at $12,000 and increases from there.

A good estimate is 1 ton for every 400 to 500 square feet of area in your house.

Off-Season Installation

Plan your air conditioner shopping and installation accordingly by avoiding the rush seasons. Instead, try to shop around during Fall or Spring when the cooling system market is not that busy. 


In relation to installing air conditioning units during off-months, some companies and manufacturers offer rebates during these periods. You can also research state or local organizations that offer incentives for installing energy-efficiency units.

AC replacement is a BIG deal. So many quotes were out of my budget, with research I was lucky to find Half the price, so I was able to get a top of the line unit. The communication was timely and supportive. ❤️ This company is so pleasant to work with. Don't hesitate to purchase through them!
Cory Schwitek
Everything about this company from start to finish was very professional and pleasing. The entire team has been very personable and a pleasure to work with! Also, the amount of savings from other quotes I received was very sufficient. I would recommend this company to everyone.

I had heard advertisements on the radio but was skeptical as to whether this was a legit company or if they were going to try the bait and switch. But with AC systems being as expensive as they are, I thought I would check them out. I called and talked to someone who actually lives in the Valley and she was very nice and answered all my questions and really put me at ease. I placed an order after shopping around and they called quickly and said that one of their installers would be in contact soon. Within a couple hours, they had contacted me and were out the same day to check everything out. They made suggestions but there was no pressure to do anything I did not want to do and were honest about what I "could do" and what I really "should do". They were flexible and quick and had my AC installed in a couple days.

When I called the office, Cathy was very patient and explained everything fully. I asked if she could recommend an installer that would not try to upsell me as I am a single woman and don’t know anything about HVAC units. She set me up with an installer who was fabulous! NewACunit’s prices were so much better than anyone else’s and I was treated with respect. I would recommend them to anyone in a heartbeat! In fact, I just recommended them to my boss this morning

I was in need of a new AC unit. My current HVAC maintenance company provided me a quote for $10,170. I searched the Internet for other options and came across The website was very easy to navigate through. I called them and they were able to answer all my questions. I ordered the exact Goodman unit online. They came out the next day and did their site inspection. They had contracted Martin Air to do the install for me 8 days later. Martin Air had completely installed my new AC unit in 3 hours time. NewACUnit and Martin Air were very professional, friendly, and a huge cost savings for me. I had saved $4,089 going with them for the exact AC unit, warranty, etc. Give them a call you won’t be disappointed.

I had a couple of traditional HVAC companies out for a quote. The sticker shock was significant. So I did some more research and found NewACUnit. The website was extremely easy to navigate and someone from NewACUnit was always available to answer questions and follow up throughout the process to make sure the installers were performing. The best part was the savings. I saved ~25% over the cheapest quote from the other HVAC guys and more than 32% for the most expensive quote.
Valerie Marsh
Went through them to purchase our new unit, long overdue! Super easy to use website that walks you through choosing the best unit with easy to answer questions, the BEST sales pitch! I got to take as long as I wanted to look through and decide without having a salesperson pressure me into something I didn't want or couldn't afford! The whole process took about 10 min at max. A very nice rep contacted me a few days later to ensure the contractor had reached out and answered any and all questions I had. I feel very safe and comfortable with my purchase so far. Would HIGHLY recommend to any homeowner! It's easier and safer than you think!

I called for my home and I saved two thousand dollars. They were professional and helpful. I have another property and I will definitely use them when it's time to replace the next AC unit. I would recommend them to my family and friends because of the money I saved and they were quick to get the unit installed. I am very happy with them!! Great company!
