Products & Services
Air Conditioning
Installations Whether a brand new home, or an air conditioning replacement, we have installed thousands of central A/C systems in Fenton and its outlying suburbs. We first determine what size unit is appropriate for the home before making suggestions for the brand and model. When it comes to central air conditioning units, bigger is not always better, which is why we do a complete home assessment first to determine your home's specific needs.
Maintenance Yearly maintenance of your home's A/C system is critical in order to ensure in-home comfort all summer long. The Hely system check is unparalleled in quality and thoroughness, going through each component of the system one by one to guarantee that it is running at optimal efficiency.
Repair Your family's comfort is our number one priority, and we provide around the clock emergency service to make sure that none of our valued customers are without air conditioning. The Hely air conditioning repair team are experts at getting an A/C up and running efficiently at the lowest possible cost to you.

My installation of my air conditioning and heating was done in one day. The gentleman who was involved in the installation was very courteous, professional, and answered all of our questions. He gave a demonstration of everything and how it works and gave us his phone number in case we had any questions later on. He cleaned up everything and hauled the old unit away. From the time I called until the installation was done was just a matter of a couple of days. The price was in our budget as well. So appreciative of this company. Would recommend it to anyone.

Customer Testimonials
Responsive, professional, and fair.
Hely Heating & Air Conditioning, has always been thoroughly professional and consistent. I had them install an entire HVAC system in 2014, and have had a maintenance agreement with them since that time, so I see them at least twice a year. They are knowledgeable, competent, on time and reasonably priced. It is reassuring to know such an expensive investment in equipment is being well cared for at a reasonable price!!
Outstanding service today. Came home to the house at 89 degrees and was very impressed with the service on the phone and also to the gentleman who came out to fix the AC unit. We want to thank you very much and we will be using your service in the future. Again, thank you
Fantastic locally, family owned. Honest, quick, reliable professional service.
Great experience! Would definitely recommend and will be using/referring in the future.
