What factors affect the cost of an AC installation?

  • The home you have: The square footage, age, insulation, and layout of your home will determine AC size. AC size plays a role in both the upfront cost of a system and monthly energy bills. Because of its importance, we take additional precautions to properly size AC systems prior to installation.
  • The system's efficiency rating: Every AC system is rated for efficiency by a SEER score. SEER is important because it determines the cost savings you'll receive over the system's lifetime. Higher SEER ratings equate to lower energy bills on average, but also increase upfront system cost. A Comfort System expert can help you find the perfect balance between upfront cost and efficiency.
  • Home modifications: It's sometimes necessary to make updates to a home prior to installing a new air conditioner. The most common modification will be to a home's ductwork. But plumbing and electrical modifications may also be required. We can help identify any necessary modifications during your free in-home estimate.

The best place to start is with a free in-home estimate

Customer Review

They were able to install the system within 24 hours...

As soon as we moved into our new home, our HVAC unit failed on us. Luckily, we chose to rely on Comfort Systems to install our new equipment. They were able to install the system within 24 hours. We are beyond thankful for Mike and Jimmy for a seamless installation, and for now having working A/C in the heat of June.
