Volusia County Air Conditioning Service and Repair

Whether you’ve been in Central Florida for 50 years or you’re a brand new arrival, you know that air conditioning is a necessity for a comfortable home in the warm months of late Spring, Summer, and early Fall. Those times of the year, being indoors without air conditioning can be almost unbearable at times, so if you are experiencing a problem with your air conditioning service and repair, you don’t want to take a chance with anyone but an experienced professional. That’s where Koontz Heating & Air comes in. In business since 1967, we have over 50 years of experience repairing and maintaining air conditioning systems in Volusia and Flagler County.

We know when your AC goes out, you want it working fast

Air conditioning systems never seem to go out when the weather is nice. It’s always that first heat wave when we get all of the calls. Often it’s the first time the system has been running for long hours in several months. It’s logical that’s when the system will experience a problem.

Logical explanations don’t make your home any cooler though, and we know that. That’s why we do everything we can to get someone out to you within a few hours of when you call us. Our hope is that we can repair the system and get your life back to normal while we are there the first time. But even if that’s not the case, the sooner we get there, the sooner you have a working air conditioner and a comfortable home.

We are the AC Contractor of choice for many area homebuilders

Aside from AC repair and maintenance, we have been the AC repair in Volusia County & heating repair company of choice for many new home builders in the area for decades. What that means for you is, if you are having a problem with your air conditioner and your home was built in the last 10 years, there is a good chance we installed the unit. That means we may have a record of how the ductwork was run and the overall specifications of the system. If you’re not sure, check your unit and see if there is a Koontz sticker on it. If you do see our sticker, please check with us before you have anyone else work on it. If we installed it we may have warranty information on your unit, even if you don’t.

Our AC Repair Technicians

All of our technicians are friendly professionals who are NATE-certified and factory-trained. They have the knowledge and diagnostic equipment needed to figure out your problem quickly, and can often repair it on their first visit to your home. We also pride ourselves on providing more than a job for our technicians, all of our employees have a career with us. For that reason, some of our staff has been with us for over 20 years, and the average time our employees have been with us is over 10 years. That means they know the systems and may have worked on them before. In some cases, they may have been the technician that originally installed the system that’s in your home when it was under construction.

If you are experiencing problems with your Air Conditioning system, call Koontz today for a free estimate on getting your home comfortable again.

Have used Koontz since I built my new home in 8/2006 and my daughter's. Worked with Chris Koontz to design system in my home- 2 units plus active returns in all bedrooms and 2 main returns. He is extremely knowledgeable and a great person to work for. His installers and techs are extremely knowledgeable and if they do not know the answer they are not hesitant to call the a/c vo. rep.for guidance. Hey just replaced 4 units in My home and my daughter. The office staff is always helpful.
Excellent and very quick response Thank you Jennifer, Jonathan, and Karen
