What our customers say

Our HVAC went out and they came out asap and helped us with getting a new system that was affordable for us. The service men Eddie and Gene were very professional and respected our home. If they needed to do anything they would let us know before hand. I would recommend them to anyone! Thank you!

Gene and Eddie did a fantastic job installing my new A.C. unit. I highly recommend HEP.

De F.

We had a new a.c. unit installed. The technicians, Eddie Hawkins and Gene Cross were absolutely amazing. They installed the unit, cleaned all the mess up and made sure everything was properly working as suppose too before they left. Even though we just purchased our house almost a year ago and was not expecting to do any big upgrades right away, unfortantely we had no choice, if we wanted too stay cool this summer. I'm so so so so thankful that we had one of the best ac salesman, Bob come and explain everything too us. He came out, by himself the week before, then on Monday came back too our home with techs too go all thru our home too make sure we made the right decision on which unit we should purchase for the square footage. This company, in my personal opinion is truly the best!!!! You are not just $$$$ too them, they treat you like family and will help you anyway they can. We will definitely be using them in the near future for other upgrades in our home.... Thank you so sooo much!!!!

HEP to the rescue!! We had a very old unit (27 year) had been babying it for a very long time. Well it finally crashed. We checked around for prices and time for installation. When we called HEP it was because of the 0% financing. Rick Louders was the man you came out and gave us the estimate. A very nice man. He actually met up with my husband in a parking lot to finalize the deal. They set up for 2 days later for the installation and were even able to call an get it bumped up a day. That was yesterday...a miserable hot day. The 2 men that came to the house to do the job were George Williams and Bo (sorry didnt catch his last name). They were very friendly and kind. I really felt sorry for them working up in that hot miserable attic. But work they did. Wouldnt even take a bottle a cold water I offered them said they had some. I want to say THANK-YOU SO MUCH! YOU BOTH WORKED SO HARD! MUCH APPRECIATED!

Joe Brown and Cole Scarborough went above and beyond my expectations today with the install of my outside unit and AC work. I highly recommend theses guys, very quick and professional service.

Brandon N.

I have just purchased a HVAC system from HEP. I have been considering replacing my system for several years and have had two very reputable companies come out and look at my existing system to give me quotes. I wanted one more company's advice before I made the big decision. Bob and Richard came out. They were an impressive and knowlegeable team. They found things that neither of the other two companies found, explained and clearly showed me the problems, and explained in detail how they would replace my system. Their process seemed far more comprehensive than the others, and I felt confident Bob and Richard knew exactly what they were talking about and what HEP would do and provide. They were first class gentlemen, willing to go the extra mile. This system costs a little more than the others, but I feel confident the service and the equipment I am getting from HEP is well worth it. As a bonus, Carrier is Made in America. Thanks Bob and Richard!

Joshua McCarty just performed maintenance agreement air conditioning check at our house. He was very friendly, professional, and helpful in his explanations concerning our equipment and its maintenance. Good Job--thank you. Dennis Young, Kingston.

Dennis Y.

Gene Cross and Eddie Hawkins did an awesome job installing a family member's new unit today. They were very nice and fully explained the unit and how it functioned which was greatly appreciated.

Annetta A.

Had a complete AC system replaced. HEP was fast and professional from start to finish. All questions were answered and work completed right the first time. The technicians ( Richard and Will ) made sure everything was working as it should and fully tested the new system completely before signing off. The old system and all packaging were all removed. Great experience with HEP Inc. Would highly recommend. Thank you, HEP Inc!

Reliable Heating and Air Conditioning Services in Karns by HEP

The climate in Karns brings muggy summers, crisp winters, and a healthy dose of springtime pollen. Comfort indoors hinges on a responsive heating and cooling system that adapts to dramatic shifts in temperature and humidity. HEP delivers comprehensive heating and air conditioning services that keep homes in Karns comfortable, efficient, and safe all year long. The company’s certified technicians diagnose, repair, maintain, and optimize every component of a residential HVAC system, ensuring top performance even during peak weather demands.

Why Proactive HVAC Care Matters in Karns

Karns homeowners often discover that a single day can jump from cool to sweltering, then back again at night. These swings place extraordinary stress on air conditioners, heat pumps, furnaces, and ductwork. A well-maintained system:

Holds indoor temperatures steady, reducing the discomfort of sudden outdoor changes
Operates at optimal energy efficiency, lowering monthly utility bills
Minimizes carbon footprint by using less electricity and cleaner refrigerants
Reduces the risk of surprise breakdowns during temperature spikes
Enhances indoor air quality by trapping allergens, pollen, and mold spores
Extends the useful life of costly HVAC equipment

HEP’s service plans empower homeowners to reap these benefits while avoiding inconvenient or expensive emergency repairs.

Comprehensive Air Conditioning Services

Air Conditioner Repair

When the thermostat shows 98 °F outside but the vents blow warm air, Karns residents need fast and reliable help. HEP technicians arrive with fully stocked service vehicles and advanced diagnostic tools. Common AC problems they address include:

Refrigerant leaks leading to ice buildup on the evaporator coil
Electrical faults in the capacitor, contactor, or circuit board
Defective blower motor causing poor airflow throughout the duct network
