Installation, Service and Repair
Efficient heating or cooling isn’t possible without a system designed to meet your home’s unique needs. That’s why we start every installation project with a full load calculation to determine your home’s heating or cooling requirements. We then work directly with you to pick out a system that’s sized properly. Once we have the system in hand, we work diligently to make sure it meets or exceeds manufacturer specifications, setting you up for efficient climate control for years to come.
At Ray’s HVAC, we think the best approach to repairs is prevention. Our air conditioning service professionals offer annual preventive maintenance to clear up any emerging issues before they can become big problems.

Even well-maintained systems suffer from occasional performance issues, and our heating and air conditioning repair team is always ready to fix those issues. We’re a proud Carrier Factory Authorized Dealer and thanks to the extensive training we received at their facilities, you can count on us to know everything there is about the world’s most effective and efficient cooling and heating systems. While our designation as a Carrier FAD ensures you we know these systems inside out and backwards, we are also fully qualified to fix all makes and models of HVAC equipment.

You depend on climate control systems throughout the year, and you ought to be able to depend on your service providers, as well. Most of our technicians hold NATE certification, the most highly regarded credential in our industry. NATE-certified technicians have been through a rigorous training process, and we supplement that training with extensive professional development.
Comfort is our business, and that means you should be comfortable with our business practices as well as our services. We always provide up-front estimates and never begin work without clearing it with the homeowner first. Our technicians will arrive on time for every HVAC repair or service visit and maintain open communication. Rest assured we always clean up the job site before we leave. That commitment to excellent service has made Ray’s HVAC a trusted part of the community since the 1950s.
