What our customers say

Jacob and Patrick came and fixed my daughter and her fiance's air-conditioning in their home ASAP while she was away having surgery. They were very fast.

Lisa G.

Blown away by the quality of the HEP HVAC technicians. These guys are head and shoulders above their competitors. Patrick and Jacob showed that they really take pride in what they do and took the time to walk me through all the options and find the best solution to fit my needs. Rather than pour money into an ancient machine, I got a great deal on a new unit, and now my house is far more comfortable and utility bills far lower. Do yourself a favor and call these guys they’re the best in Knoxville.

Charles C.

Patrick was awesome. A/C was working fine yesterday morning. I was in and out of the house working all day, but when I came in yesterday afternoon, the A/C was kicking on. I did some troubleshooting myself but to no avail. We just sold our home, and the home inspection for the buyers was the next day! Middle of summer and a home inspection the next day. Could there be a worse time for the A/C to go out? I called HEP and asked them to come out the same day. Any fee they charged me was well worth it if we could at least diagnosis the problem. They did more than just diagnose the issue, however, and spent the next three hours fixing the problem. Three hours in the middle of summer, on a holiday (July 4), and at night (9-11 PM). Patrick saved my butt. Before he left he had everything working just the way it was supposed to work. Thank you, Patrick and HEP!

Zachary D.

This week our capacitator went out on our ac unit. Called HEP at 6pm, had a tech arrive by 7pm and my ac was working again by 7:30. Our tech Nathan fisher was very nice, knowledgeable, and got the job done fast.

Robin M.

Justin the hep teck went about and beyond will be using them again for all of my heating and cooling needs!!!!

Jeff A.

We had an issue with our heat/air system that was installed in Dec. Called the company to report issue. Even though it was after hours. The service tech, James, was here in maybe 1 1/2 hrs. He was very friendly and very helpful. He had the problem fixed in no time. And air was back on. Thank you so much James. And thanks to the person who answered the phone when I called. Sorry I don't remember her name. We have used this company alot the past few years. And we have never been disappointed.

Sandy M.

Jacob and Ryan were very professional and did great work very satisfied with the new system and there service

Air Conditioning Repair and Troubleshooting

Even a seemingly minor symptom—like a faint rattle or slight drop in airflow—can spiral into a full system shutdown if ignored. HEP responds quickly with fully stocked service vehicles, minimizing downtime.

Common Problems Resolved by HEP Technicians

Refrigerant leaks in evaporator coils or line sets
Failed start or run capacitors
Burned contactors or relays
Clogged condensate drains leading to water damage
Blower motor bearing failures
Faulty thermostat sensors causing short cycling
Frozen evaporator coils from restricted airflow or low charge

Troubleshooting proceeds logically: verifying thermostat inputs, inspecting high- and low-voltage connections, measuring refrigerant pressures, and checking temperature differentials across the coil. This systematic approach prevents unnecessary parts replacement and restores cooling quickly.

Preventative Maintenance and Tune-Ups

Mountain City’s mixed climate means AC units often sit idle through cold months, allowing dust accumulation on coils and microbial growth in condensate pans. Regular tune-ups add years of life, improve efficiency, and catch issues before peak season.

Typical Spring Maintenance Checklist

Remove debris from outdoor condenser fins
Clean and straighten aluminum coil fins for optimal airflow
Tighten electrical connections and test capacitor microfarads
Measure refrigerant charge under manufacturer-specified conditions
Flush condensate drain and add biocide tablet
Replace or clean air filters
Calibrate thermostat and verify cycle times
Record static pressure to identify hidden duct restrictions

Indoor Air Quality Solutions

Comfort is more than temperature; it also involves the purity, humidity, and freshness of breathing air. HEP integrates indoor air quality (IAQ) improvements with core HVAC services, creating a holistic system that nurtures health as well as comfort.

IAQ Enhancements Often Recommended

Media air cleaners with MERV 11–16 filtration
UV-C lamps targeting coil and drain pan microorganisms
Whole-house dehumidifiers to combat sticky summer nights
Energy recovery ventilators (ERVs) for balanced fresh air intake
Sealed combustion furnaces to reduce indoor pollutant introduction

Energy Efficiency Measures

Electricity rates in Mountain City can spike during peak cooling season. An efficient HVAC system lowers operational costs and reduces environmental impact. HEP prioritizes efficiency in every recommendation, from variable-speed compressors to smart thermostat integration.

Strategies That Drive Efficiency

High-SEER heat pumps for both heating and cooling
Variable-capacity compressors that modulate output according to load
Electronically commutated motors (ECMs) for quieter, lower-wattage airflow
Zoning dampers that deliver conditioned air only where needed
Insulated supply and return ducts to avoid thermal loss in unconditioned spaces

Advanced HVAC Technologies

Modern air conditioners incorporate innovations that once seemed futuristic. HEP stays ahead of the curve by mastering these tools and presenting them to Mountain City occupants who want the latest in comfort technology.

Noteworthy Innovations

Inverter-driven compressors that adjust capacity in 1% increments
Wi-Fi enabled thermostats with geofencing to anticipate occupancy
Integrated heat pump water heaters that recycle waste heat
Ductless multi-zone systems with sleek indoor cassettes
Sensor arrays measuring humidity, VOCs, and CO₂ for automated IAQ adjustments

Ductwork Design and Sealing

Above-ceiling ductwork is often the hidden culprit behind hot spots, noisy airflow, and poor efficiency. HEP evaluates existing ducts for leakage, improper sizing, and restrictive fittings, then provides corrective options.

Signs of Duct Issues

Rooms furthest from the air handler remain noticeably warmer
Excessive dust despite frequent cleaning
Hissing sounds when the system is running
High static pressure readings during maintenance visits

Sealing solutions include mastic, foil tape, or aerosolized sealant applied internally. In renovation scenarios, rerouting ductwork or adding return air pathways balances pressure and improves overall comfort.

Heat Pump and Dual-Fuel Systems

Mountain City’s milder shoulder seasons align perfectly with heat pump technology, which transfers heat rather than generating it. Pairing a heat pump with a gas furnace in a dual-fuel configuration provides an optimal blend of efficiency and rapid heat recovery during extreme cold snaps.

Benefits of Dual-Fuel Arrangements

Lower electric consumption in moderate cold
Automatic switch to gas heat below programmed temperature thresholds
Extended equipment lifespan via reduced run time on each fuel source
Quieter outdoor operation in heating mode compared to traditional AC units paired with furnaces

Thermostat and Control Upgrades

A thermostat acts as the brain of any HVAC system. Older mercury or basic digital units cannot leverage modern equipment’s full potential. HEP offers control upgrades that synchronize comfort and conservation.

Control Features That Transform User Experience

Learning algorithms that adapt to daily usage patterns
Humidity setpoints for precise indoor moisture control
Multi-stage equipment coordination to reduce compressor cycling
Energy reports accessible via smartphone apps

Seasonal Considerations for Mountain City Residents

Transition seasons place unique demands on comfort systems. Spring often features cool mornings and warm afternoons; fall brings crisp nights ideal for heat pump operation. Proper configuration ensures smooth handoffs between heating and cooling modes.

Spring Preparation Tips

Schedule maintenance before temperatures climb
Replace winter filters clogged with dust and pet dander
Clear vegetation around outdoor units to guarantee airflow

Autumn Preparation Tips

Test heat mode on a mild day to catch ignition issues early
Inspect insulation around refrigerant lines
Verify that auxiliary heat strips engage only when necessary

Common Warning Signs Your AC Needs Service

Recognizing early indicators prevents costly breakdowns in mid-July. HEP encourages homeowners and facility managers to stay vigilant.
