Called Dean's for help with my heating unit, they were gonna charge me 400 bucks that hep would do for 200, thanks hep because of your quick price quote, you saved me much needed money this close to Christmas. Thanks for the hep haha

Jaeda B.

I use HEP for my HVAC units and have been very satisfied with their service. One of their service technicians, Doug, recently serviced one of the units. He immediately diagnosed the problem, ordered a new part, and installed the new motor the next day, just like he said we would do. Highly recommend HEP.

Lou K.

Thank you HEP for outstanding performance and customer service. I called HEP and they came to the rescue and fixed my AC unit. And did it very professionally answering all my questions and explaining everything. The best part of it all was the price, being way less than I had in mind. I will recommend to anyone! Thanks again!

I am writing you to let you know how well your company was represented today. Your dispatch sent two techs to our home to investigate our HVAC problem. I was impressed with their knowledge and relaxed manor. They quickly determined the issues and presented me with the options. They did not try to rush me or rush through the service call. This time of year, I know you are in high demand. I had just paid our annual maintenance contract with our current service company. We have been using them for a number of years. Our downstairs HVAC system started acting up Saturday evening. Back in February the tech added 2 pounds of Freon to the downstairs unit and said I needed a $450.00 leak check, and he would have the office call and schedule it. They did not. That was the 2nd time they failed to follow up within the last 2 years. Then on the current service call, the tech told me my compressor was most likely bad, “it had open windings”, and it needed to be replaced. He might be able to get it to work briefly, but that would be wasting money. The ball park price for installing another compressor would be around $1800. He would have the office contact me with the actual price. Two days later, and we had not heard from them. Meantime, we had no HVAC downstairs. I decided to call another service provider. An internet search brought your listing up. That and your current TV ad campaign made me decide to give your company a try. Your techs were able to identify the problem as a defective start capacitor and a weak run capacitor. Your techs made a great first impression for your company. I feel they went above and beyond what they had to do. After the compressor started running the pressures were all in the normal ranges which indicates that if I have a leak it is most likely very small. I have decided to go with your company as our HVAC service provider. It will be up to the future techs that your dispatch sends to keep my business. If they are as nice and helpful as those today were, then I’m sure we will do fine together.

HEP has been wonderful. I created an electrical problem which when I call HEP they sent out a tech who fixed it and then looked at my heating unit. I have known for sometime that the unit needed to be replaced. Doug was kind enough to evaluate the current system and at his suggestion I asked for a salesman to meet with me. He was kind enough to get the salesman here the same day and I purchased a unit that they are installing now. It has been like clockwork, each piece of the puzzle coming together. HEP you have a great team that knows how to work in sync. Thank you so much.

Priscilla J.

I moved to Knoxville almost two years ago and have used HEP for all of my plumbing and HVAC needs including replacement of my water service line and my entire plumbing system. The latest project was the replacement of my existing aged electric heat pump with a Trane split AC and gas heating unit. The final product was a five star installation; however, they had to come back to make some major final adjustments. Their employees are always courteous and professional. I will continue to use HEP for all of my needs.

George F.

I had purchased a Service Contract through HEP and I called for a A/C Service. When the technician arrived, he explained his process and what to expect of the service. Once the service was completed, I was informed on the status of my A/C Unit with no intentional try to upsell. No Pressure, just friendly service.

Troy O.

We had an appointment for a maintenance check up for a Friday afternoon with no specific time. Hep called ahead before coming. We were not ready for them to stop by and the service man politely asked for a time and showed up exactly when I asked him to. My husband had a lot of questions about our new heating system and the serviceman politely and patiently answered them all.

Jellico Climate Challenges and Their Impact on Heating Equipment

Nestled in the Cumberland Mountains, Jellico experiences swift weather swings that place extra strain on mechanical and electrical heating components.

Winter Extremes and Freeze-Thaw Cycles

Intense overnight freezes followed by daytime thaws create thermal shock within heat exchangers. Metal expands and contracts, stressing weld seams and gasketed joints. HEP technicians inspect for micro-cracks, hairline fissures, and compromised burner alignments before these issues escalate into hazardous flame-rollout conditions.

Humidity Swings and Indoor Comfort

While January brings low dew points that desiccate rubber belts and seals, spring often arrives with higher humidity that condenses inside vent stacks. The alternating moisture levels can corrode flue liners or short-circuit pressure switches. HEP calibrates drainage slopes, installs condensate bypass traps, and applies anti-rust sealants to defend against Jellico’s unpredictable moisture profile.
