How Much Does a New Air Conditioner Cost?

Most new air conditioners or cooling systems will cost around $6,000 – $8,000. This range includes all the equipment, installation, permits, inspections, labor, electrical, basic accessories such as thermostat, etc. Major factors of the price include the size of the home, where is the actual equipment located (attic, crawlspace, mechanical room, etc.), how old the home is, and even what type of fuel the system uses.

The average to replace the entire HVAC system overall will be in the $8,000 - $12,000 range when including both air condition system AND heating system. With additional upgraded options and accessories (see example list below), a full heating & cooling system replacement could run as much as $20,000+.

Most basic system installations do not include the items listed under “system enhancements & accessories” but all of them can enhance the performance of the system and help maximize the comfort, energy efficiency, convenience, air quality and overall indoor environment within your home. This is why we like to have a comfort advisor come to your home to do a full evaluation and talk to you about your options, concerns and what is important to you.

Another issue that is not talked about often is the difference in contractors in the HVAC industry. This leads to questions that a consumer should ask to help them decide the type of provider they want to work with and what is most important to them. Ultimately, the contractor is the most important variable, not the brand or type of equipment purchased. What is most important to you? Warranty? How long the company has been in business? How many technicians do they have? Are they available after normal business hours and on weekends? What type of training and certifications do their technicians have? How many systems have they put in? Do you know anyone that has used them? How are their online reviews? Do they perform background checks and drug testing on their team members? Do they show up in uniforms in clearly marked vehicles? Are they involved in the local community? Are you comfortable with the office staff, technicians and sales people? Were they easy to get in touch with? Did they take the time to explain to you what they were doing and did they really look at the existing system and evaluate the home? Was the ductwork evaluated? What type of filtration or air purification system was discussed or reviewed? Do they have proper insurance and licenses? Are they getting a permit to perform the work? These questions could go on and on.

All these questions can be important when evaluating what is best for you personally and your home. We like to compare new systems to good recipes such as apple pie. Most of the time you hear that you want to compare apples to apples but in the contracting world, it’s not that easy. A better comparison would be comparing apple pie to apple pie. Some of the ingredients may be the same but the finished product is most likely not the same. This is false when making a decision about having a new comfort system installed. Ultimately, the most important factor is your personal comfort level with the company that is going to install the new system. This is much more important than the brand or type system to be installed.
