My wife and I had problems with our outdated HVAC system. We did some calling around and settled on HEP. Mr. Lee Swann came out the same day to have a look, as it turned out we were on our last leg with the HVAC system we had. He talked us through our options, Mr. Lee was very professional, and very knowledgeable in what we needed and why it was in our best interest. The next day Mr. Ronnie Trout and Mr. Jeremey Hidden were on station. As individuals and as a team they were outstanding, recommendations were made based on years of experience. Attention to detail at every step was outstanding. This was exactly what my wife and I expected as two retired US Army noncommissioned officers. They did not disappoint in any way. We would highly recommend for any future projects. Thanks for al the professionalism.

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!

Expert HVAC Unit Replacement in Reliance

Reliance homeowners and property managers depend on a steady flow of conditioned air to stay comfortable through scorching summers and brisk winter nights. When an aging furnace struggles to keep up or a faltering air conditioner starts consuming excessive electricity, HVAC unit replacement becomes the most practical path forward. HEP specializes in turnkey heating and air conditioning replacement services in Reliance, providing modern, energy-efficient equipment paired with meticulous installation practices that extend system life and optimize indoor comfort.

Why HVAC Unit Replacement Matters

Even the most meticulously maintained heating and cooling systems have a finite lifespan. Over time, motors wear out, refrigerant leaks develop, and cracked heat exchangers pose safety concerns. Attempting to patch an obsolete unit often delivers only temporary relief. By investing in a full HVAC unit replacement, property owners in Reliance gain:

  • Higher overall system efficiency, reducing monthly utility costs
  • Enhanced comfort with more consistent temperatures and balanced airflow
  • Improved indoor air quality through advanced filtration and ventilation options
  • Peace of mind from up-to-date safety controls and manufacturer warranties

Signs Your System Needs Replacement

Ignoring early warning signs can lead to sudden breakdowns at the most inconvenient times. Key indicators include:

  • Frequent repair calls within a single season
  • Rising energy bills despite consistent usage habits
  • Uneven temperatures from room to room
  • Excessive noise, rattling, or buzzing during operation
  • Persistent humidity problems or a musty indoor smell
  • Equipment age exceeding 12–15 years for air conditioners or 15–20 years for furnaces

By addressing these red flags promptly, Reliance residents avoid emergency scenarios while reaping the benefits of a modernized HVAC setup.

HEP’s Comprehensive Heating and Air Conditioning Replacement Services

HEP approaches each HVAC unit replacement as a tailored project rather than a one-size-fits-all task. From the initial load calculation to the final performance verification, every step is executed with precision and full compliance with local building codes.

Tailored System Design and Sizing

Proper sizing lies at the heart of efficient heating and cooling. Oversized equipment short-cycles and wastes energy, while undersized units struggle to reach set temperatures. HEP’s certified technicians calculate:

  • Manual J heat gain and heat loss for the specific property
  • Ductwork layout, static pressure, and airflow requirements
  • Window orientation, insulation levels, and occupancy patterns

With these data points, they recommend the exact capacity and configuration needed for optimal performance in Reliance’s climate.

Removal and Environmentally Responsible Disposal

Outdated HVAC components often contain refrigerants or other substances requiring specialized handling. HEP follows strict reclamation procedures:

  • Recovering and recycling refrigerant to prevent atmospheric release
  • Segregating metal, electronic, and plastic parts for proper recycling streams
  • Coordinating with licensed disposal facilities for non-recyclable materials

This eco-conscious approach minimizes environmental impact while freeing up space for the new installation.

Precision Installation Techniques

A premium HVAC unit cannot perform to its rating if installation corners are cut. HEP’s crews adhere to:

  • Manufacturer torque specifications on all electrical terminals
  • Nitrogen purging during refrigerant line brazing to prevent oxidation
  • Proper evacuation and micron testing before refrigerant charge
  • Mastic-sealed duct joints for reduced leakage
  • Leveling of outdoor condensers for vibration control

These measures safeguard efficiency, noise levels, and equipment longevity.

Post-Installation Optimization and Testing

Before calling a project complete, HEP conducts a series of verification steps:

  • Static pressure readings confirming correct airflow
  • Superheat and subcooling measurements to fine-tune refrigerant charge
  • Combustion analysis on gas furnaces to ensure safe fuel utilization
  • Thermostat calibration and tutorial on advanced features

Clients receive documentation of all readings, demonstrating that the replacement system meets or exceeds manufacturer and code requirements.

Benefits of Choosing HEP for HVAC Replacement in Reliance

Comfort Enhancement

Newer HVAC technology incorporates variable-speed compressors and modulating gas valves that adapt output precisely to changing load demands. The result is steady indoor temperatures without abrupt swings, along with quieter operation that fades into the background of daily life.

Energy Efficiency and Cost Savings

Modern heating and air conditioning units boast impressive SEER, HSPF, and AFUE ratings. Paired with smart thermostats and zoning controls, these systems slash utility consumption. Reliance property owners often see double-digit percentage reductions in both kilowatt-hour and gas usage compared to retiring equipment.

Indoor Air Quality Improvements

Tightly sealed homes trap pollutants, allergens, and moisture. HEP integrates IAQ enhancements during HVAC replacement, such as:

  • High-MERV pleated filters for particulate capture
  • UV germicidal lamps to neutralize bio-contaminants on coils
  • Whole-home humidifiers or dehumidifiers to maintain ideal RH levels

The result is air that feels fresher and supports healthier living conditions.

Quiet Operation and Modern Controls

Advancements such as insulated compressor jackets, swept fan blades, and rubber isolation pads dramatically reduce sound levels. Wi-Fi-enabled thermostats allow remote temperature adjustments, energy tracking, and custom scheduling right from a smartphone or tablet.

Types of HVAC Systems Replaced by HEP

Central Air Conditioning Units

Traditional split systems comprising an outdoor condenser and indoor evaporator coil remain popular across Reliance. HEP replaces aging 10-13 SEER units with high-efficiency 16-20+ SEER models that translate immediately into cooler summers and lower bills.

Gas and Electric Furnaces

Whether a property relies on natural gas, propane, or electric resistance heat, HEP upgrades outdated furnaces with modern 95%+ AFUE condensing models or variable-speed electric air handlers. Proper venting, condensate drainage, and thermostat integration are standard parts of the service.

Heat Pumps and Dual-Fuel Systems

Mild winters in Reliance lend themselves well to heat pump technology. For homeowners seeking the best of both worlds, HEP installs dual-fuel configurations that switch between an electric heat pump and gas furnace automatically for optimal efficiency.

Ductless Mini-Splits

When older homes lack existing ductwork or additions require independent climate control, ductless systems shine. HEP’s technicians replace bulky window units with sleek wall-mounted air handlers connected to a single outdoor compressor, delivering zoned comfort with minimal disruption.

Packaged Rooftop Units

Small commercial spaces, multi-family residences, and single-story homes sometimes rely on rooftop or ground-mounted packaged units. HEP coordinates crane lifts, curb modifications, and electrical upgrades while adhering to stringent safety protocols.

The Step-by-Step HVAC Unit Replacement Process

Initial Consultation and In-Depth Load Calculations

HEP begins every project with a walk-through of the property, discussing current comfort challenges and long-term goals. Using industry-standard software, technicians calculate heating and cooling loads room by room, considering:

  • Square footage and ceiling height
  • Insulation R-values in walls, attic, and crawlspaces
  • Window type, size, and shading
  • Orientation toward sun and prevailing winds
  • Airtightness and infiltration levels

This step eliminates guesswork and lays the groundwork for proper equipment matching.

Equipment Selection and Options

Armed with load data, HEP presents a curated list of systems that align with performance targets, fuel preferences, and indoor air quality priorities. Homeowners can choose enhancements such as:
