Ensuring your heating system is operational throughout the year can be a guessing game, especially in Central Florida, where the weather naturally takes care of heating from May through September. However, when those occasional cool spells hit, you want your home to warm up quickly. Unfortunately, during these times, you may discover your heating system isn’t functioning efficiently or, worse, not working at all.

What Makes Us The Reliable Volusia & Flagler County Heating Service And Repair Company?

In addition to providing expert heating and cooling repair and maintenance services, we proudly stand as the preferred HVAC contractor in Volusia County, trusted by numerous new home builders throughout the region for many years. If you’re encountering issues with your air conditioner and your residence was constructed within the last decade, we may be the best choice to diagnose the problem. That’s because we have worked directly with so many homebuilders, we may have handled the design and installation of your AC system. Consequently, we may have comprehensive records detailing the ductwork design and overall system specifications.

For peace of mind, inspect your unit for the Koontz ‘Signature of Service” sticker—a clear sign of our involvement. If our sticker is present, we strongly recommend consulting with us before entrusting any other service provider with your HVAC system.

This precaution is particularly crucial because, if we installed your unit, there’s a possibility that we hold pertinent warranty information, even if it’s not immediately apparent. Trust in our expertise and commitment to quality HVAC repair and service in Volusia County, ensuring your system’s optimal performance and longevity.

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
