My heating and air unit completely quit on me the other day. I called HEP as they were the only ones who could come out on a moments notice. Unfortunately I had to get a whole new heating and air system (the writing was on the wall for some time, I was just waiting for the inevitable). I was financed the same day (at 8pm!!) and set up the installation. I was told it would take 6 to 8 hours estimate for the work to be done. The gentlemen that came to install the unit (Javi and Eric(?)) came on time and were very friendly and courteous and knowledgeable. They had the old system removed and the new one installed in just a little over 3 hours. I was all around very impressed with the work that was done...from the person that took my phone call the other day, to the technician that came out to diagnose the problem and helped me get financed and the gentlemen that installed the new system. Everyone was personable and knowledgeable throughout the whole process. I would definitely recommend HEP to anyone that is in need of home service that you can't do yourself.

Ronald and Aavi were on top of it from the moment they texted me they were on their way to the final cleanup and closing. They wasted no time getting busy and had the old system removed and the new one installed before I knew it. Michael, with QA/Safety, dropped by to make sure everything was going good and safe. Very professional, exceptional communication, and the finishing touch to the outside unit was above and beyond expectation. Kudo to Chase for quoting me a system that was almost half the price of another Knoxville company. It is a great day when HEP is on the way!

Unusual Sounds or Odors

Grinding, hissing, or musty smells signal mechanical or biological problems. Technicians inspect motors, bearings, and ductwork to restore silent, clean operation.

Frequent Cycling or Short Cycling

Short cycling strains compressors and spikes energy use. HEP Company recalibrates thermostats, checks heat anticipators, and inspects capacitors to eliminate rapid cycling.

Poor Airflow

Blocked filters, duct leaks, or blower motor issues cause weak airflow. After isolating the culprit, technicians reseal ducts, replace belts, or upgrade fan motors as needed.

Benefits of Choosing HEP Company for Cosby Residents

Certified Technicians with Local Knowledge

Every technician holds relevant certifications and understands how Cosby’s humidity and temperature fluctuations shape HVAC demands. That expertise ensures customized service rather than generic, one-size-fits-all fixes.

Fast Response Times Within Cosby

Localized dispatch minimizes travel time between HEP Company’s base and residents’ homes, reducing discomfort during unexpected outages.

Commitment to Environmentally Responsible Practices

HEP Company adheres to EPA regulations when handling refrigerants and promotes high-efficiency upgrades to lower each household’s carbon footprint.

Tips for Homeowners Between Professional Visits

Filter Replacement Routine

A dirty filter is the most common cause of airflow restriction. Mark a recurring reminder to:

  • Inspect filters every 30 days during heavy cooling season
  • Replace or clean based on manufacturer recommendations

Keeping Outdoor Units Clear

Ensure a 2-foot clearance around condensers by trimming shrubs, removing leaves, and clearing debris that could obstruct airflow.

Monitoring Thermostat Settings

Small changes—such as setting the temperature a few degrees higher when away—reduce strain on the system. Program schedules that reflect daily habits for hands-off savings.

Signs It’s Time to Schedule Service with HEP Company

Spike in Utility Bills

A sudden increase often indicates declining efficiency due to dirty coils, failing capacitors, or refrigerant loss.

Uneven Temperatures in Home

Hot or cold spots signal ductwork issues, improper airflow balancing, or malfunctioning dampers.

Humidity Problems

An A/C that fails to dehumidify may have an oversized capacity, low refrigerant charge, or inadequate airflow—conditions that HEP Company can evaluate and remedy.

Understanding Modern HVAC Technology

Variable-Speed Compressors

Unlike single-speed units that cycle on and off, variable-speed compressors modulate output for precise temperature control and quieter operation. HEP Company’s technicians are trained on these advanced systems, ensuring correct setup and maintenance.

SEER2 Ratings and Compliance

Seasonal Energy Efficiency Ratio (SEER2) ratings reflect new testing standards. HEP Company educates homeowners on these metrics, guiding them to equipment that meets federal efficiency requirements and local utility rebate criteria.
