Jacob Newman came out preformed a annual turn up on my hvac system was prompt and very professional

Jacob E.

Jacob Newman was able to fix a problem that I had with my HVAC fan. I was expecting to have to replace the fan motor but it turned out that the system schematic sheet had come loose and been sucked into the fan. This created a loud sound that sounded like the fan was going out. However, pulling the sheet from the fan fixed the problem. He was very courteous and knowledgeable. Thanks Jacob.

We had a 2.5-ton 80/20 split unit installed today just after ordering it last night with help from Jacob Newman. Sebastian, Tristan, and a helper who came with them were extremely courteous, friendly, and helpful. They explained everything that they were going to be doing during the installation. You could tell that had done this kind of installation enough that they probably could do it in their sleep. I showed them where the access was in the master bedroom closet and I apologized because the access opening was small. They looked and said it was nothing that hadn't seen before. Then each one started on their different task. They had to remove a closet shelf and trim around the access opening for clearance issues once they had taken measurements, (asked if it was okay before they removed anything) and replaced it like new. They all worked like machines when the outside unit was completed they came and helped the other to remove the old split unit and replace the new unit in the attic. They cleaned up any mess in the areas where they worked and looked proud of the work they had accomplished. They double-checked everything to make sure that it worked perfectly. Excellent workers especially as hot as it was in the attic. I want to also give Hep a big thank you for hiring veterans. Being a former Marine hiring veterans is always a big plus for me in any business. I thank you guys a lot.

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.

Steve C.

Friendly service, very response and helpful. I would recommend to anyone. They came out at 9pm on a Sunday night to fix A/C unit, was much needed help with a 8 and a half month pregnant wife at home.

Nathan S.

Patrick did a great job getting our HVAC unit fixed.

Brandon M.

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.

The service we received from the technicians who installed our new heating and air unit was exceptional. Tommy F. And John S. Went above and beyond to make sure that our every need was meet. The very experienced and professional techs made sure that we were extremely statisfied.

The Importance of Professional HVAC Unit Replacement in Tennessee

The average HVAC system in Tennessee works harder than many homeowners realize. From humid summer afternoons that lock in moisture to crisp winter nights that send temperatures plunging, equipment must quickly transition between cooling and heating modes—often within the same week. When an aging furnace or air conditioner can no longer keep pace, comfort, efficiency, and safety decline together. That is why HVAC unit replacement is more than a swap of metal boxes; it is a strategic investment that protects indoor comfort, property value, and long-term energy use.

HEP specializes in turnkey HVAC unit replacement services designed specifically for Tennessee’s climate and housing stock. By combining NATE-certified technicians, comprehensive load calculations, and rigorous post-installation testing, the company delivers systems that maintain steady temperatures and ideal humidity levels while trimming monthly utility bills. Homeowners gain quieter operation, modern filtration capabilities, and peace of mind knowing every component meets or exceeds current building codes.

Why Tennessee Homes Demand Reliable Heating and Cooling

Unique Climate Challenges Across the State

Tennessee’s geography ranges from the eastern Appalachians to the western lowlands of the Mississippi River Valley, producing dramatic microclimates. East Tennessee frequently experiences quick drops in temperature due to elevation changes, while Middle and West Tennessee endure prolonged heatwaves and higher dew points. These conditions place year-round stress on HVAC equipment:

High summer humidity taxes air conditioners by forcing longer runtimes for latent heat removal.
Sudden spring and fall cold snaps demand furnace readiness even when daytime highs feel mild.
Allergens such as ragweed and mold spores persist nearly all year, raising the stakes for effective filtration and ventilation.

An HVAC system designed without these variables in mind often short-cycles, struggles to dehumidify properly, and leaves certain rooms uncomfortable. Replacing an outdated unit with a properly sized, climate-matched system from HEP addresses localized weather extremes and keeps indoor conditions stable.

Energy Consumption in Variable Seasons

Fluctuating outdoor temperatures translate into spikes and dips in energy use. Tennessee’s utilities report that heating and cooling account for well over half of annual residential electricity consumption. Replacing an aging 10-SEER air conditioner with a 16-SEER or higher unit can cut cooling costs up to 40 percent, while a high-AFUE furnace significantly reduces winter fuel usage. These savings accumulate year after year, offsetting the initial replacement investment and contributing to statewide energy-conservation goals.

Signs Your HVAC Unit May Need Replacement

No piece of mechanical equipment lasts forever. Recognizing red flags early prevents emergency breakdowns and expensive damage to other home systems. HEP technicians recommend watching for the following indicators:

Frequent repairs within a two-year span
Rising energy bills despite similar thermostat settings
Uneven temperature zones, hot and cold spots, or weak airflow
Excessive noise such as rattling, squealing, or banging during operation
Visible rust on the furnace cabinet or condenser coils
Persistent humidity issues, musty smells, or worsening allergy symptoms
System age exceeding 10–15 years for air conditioners or 15–20 years for furnaces

While some issues stem from ductwork or thermostat problems, multiple symptoms together often point to diminishing equipment life. A professional evaluation from HEP determines whether targeted repairs suffice or whether a full replacement will offer superior long-term performance.

Comprehensive parts and labor warranties backed by a stable Tennessee service provider

Collectively, these benefits translate into fewer service interruptions, quieter operation, and measurable energy reductions.

The HEP HVAC Replacement Process

1. Comprehensive Home Evaluation

A qualified comfort consultant conducts a room-by-room inspection, assessing insulation levels, window orientations, existing ductwork, and infiltration points. Infrared scanning and blower-door tests may be employed to quantify heat gain and loss. This data guides accurate sizing, a critical factor in Tennessee where undersized units struggle on humid days and oversized units short-cycle before extracting enough moisture.

2. System Selection and Custom Design

Based on the load calculation, HEP recommends matched components—outdoor condenser, indoor coil or air handler, furnace or heat pump—that meet both homeowner preferences and regulatory requirements. Options might include variable-speed blowers for quieter low-load operation, dual-fuel setups that leverage efficient heat-pump heating until temperatures dip below a set balance point, or advanced filtration modules for allergy relief.

3. Professional Installation

Installation crews remove and responsibly recycle old equipment before placing new units on vibration-isolating pads or securely mounting furnaces in attics or crawl spaces. Proper refrigerant line sizing, brazed connections with nitrogen purge, calibrated torque on electrical lugs, and sealed plenums ensure long-term reliability and code compliance. HEP follows current ICC and ASHRAE guidelines to guarantee safe combustion venting and condensate disposal.

4. Commissioning and Performance Verification

A new HVAC system reaches full potential only when airflow, refrigerant charge, and combustion parameters sit within precise tolerances. HEP technicians measure static pressure across the duct system, verify temperature splits, and record superheat or subcooling. Results are documented and left with homeowners alongside digital operation manuals and maintenance schedules.

5. Final Walk-Through and Education

Homeowners receive a tutorial on thermostat programming, air-filter replacement intervals, and how seasonal maintenance protects warranties. This hands-on orientation demystifies settings, promotes energy-saving habits, and reinforces HEP’s commitment to long-term system performance.

Energy Efficiency and Environmental Impact

Lower Utility Consumption

Energy-efficient HVAC replacement offers immediate and ongoing savings. In cooling mode, higher Seasonal Energy Efficiency Ratio (SEER) ratings translate into fewer kilowatt-hours per BTU removed. Modern heat pumps often exceed 20 SEER, while furnaces showcase Annual Fuel Utilization Efficiency (AFUE) ratings above 95 percent. Over a decade, reduced utility expenses recapture much of the system cost.

Reduced Carbon Footprint

Cutting electricity demand lowers greenhouse-gas emissions associated with regional power generation. High-efficiency gas furnaces combust fuel more completely, minimizing CO₂, NOx, and particulate production. Pairing HVAC upgrades with smart-home controls such as occupancy-sensing thermostats compounds ecological benefits by automatically scaling output when rooms are unoccupied.

Environmentally Responsible Refrigerants

Legacy air-conditioner refrigerants such as R-22 are being phased out due to ozone depletion. HEP installs systems utilizing R-410A and emerging low-GWP (Global Warming Potential) blends that meet future regulatory requirements. Proper recovery and recycling of legacy refrigerants during replacement prevents atmospheric release and aligns with environmental stewardship.

Advanced Technologies Available Through HEP

Variable-Speed Compressors

Traditional single-stage compressors operate at full capacity or shut off entirely, creating temperature swings and higher energy spikes. Variable-speed technology modulates output to match precise cooling or heating demand. Homes experience steadier temperatures, improved humidity control, and lower sound levels inside and outside.

Modulating Gas Valves

Gas furnaces equipped with modulating valves adjust flame intensity across a broad range. This fine-tuned combustion maintains consistent supply-air temperatures, eliminating frequent starts and stops. Homeowners notice quieter operation and fewer drafts caused by rapid duct temperature changes.

Smart Thermostat Integration

Wi-Fi-enabled thermostats integrate seamlessly with new HVAC systems, allowing remote monitoring, automated scheduling, and energy-use analytics. Some models employ geofencing to reduce output when occupants leave and restore comfort before they return. HEP ensures compatible control wiring and provides initial programming guidance.

Enhanced Filtration and Air Purification

Optional high-MERV filters, electronic air cleaners, and UV-C lamps capture and neutralize pollen, bacteria, and volatile organic compounds (VOCs). Tennessee’s persistent allergen load makes these upgrades especially valuable for households with respiratory concerns. When paired with properly balanced airflow from a new system, indoor air becomes noticeably fresher and cleaner.

Building Code Compliance and Safety

HVAC replacements must meet the International Residential Code (IRC) and local Tennessee amendments. HEP follows all mandated protocols, including:

Correct flue-pipe sizing and slope for gas appliances
Mandatory overflow safety switches on secondary condensate drain pans
Proper clearances to combustibles and attic walkway installation when required
Electrical disconnect placement within line-of-sight of service panels
Secure refrigerant line insulation to prevent energy loss and condensation

Permit documentation and scheduled inspections confirm compliance. Adhering to these standards not only ensures occupant safety but also protects home insurance coverage and future real-estate transactions.

Indoor Air Quality Enhancements After Replacement

Balanced Ventilation

Older HVAC systems often relied on incidental leakage for fresh-air exchange, leading to inconsistent indoor humidity and pollutant buildup. New equipment can incorporate dedicated ventilation options such as energy-recovery ventilators (ERVs), which introduce conditioned outdoor air while conserving heating and cooling energy.

Humidity Control

Properly sized air conditioners and heat pumps extract moisture more effectively, preventing mold growth and protecting wood flooring and furniture. In winter, optional whole-house humidifiers maintain optimal relative humidity, reducing static shocks and respiratory discomfort.

Filtration Upgrades

A newly replaced system eliminates bypass gaps and provides sealed filter cabinets. Homeowners may choose media filters rated MERV 11–16 for superior particulate capture without compromising airflow, an option often impossible with undersized or obsolete equipment.

Maintenance After Replacement

Protecting the Warranty

Manufacturers require periodic service to uphold parts warranties. HEP offers annual maintenance agreements that include:

Inspection and cleaning of evaporator and condenser coils
Lubrication of moving parts, if applicable
Verification of refrigerant charge and system pressures
Combustion-efficiency testing for furnaces
Thermostat calibration and software updates
Replacement of disposable filters

Sticking to a scheduled maintenance plan sustains peak efficiency and uncovers minor issues before they become major repairs.

Extending System Lifespan

Regular attention keeps motors, heat exchangers, and compressors operating under ideal conditions. Dust buildup, refrigerant imbalances, and clogged condensate lines strain components and accelerate wear. Proactive tune-ups preserve airflow, uphold energy ratings, and delay the next replacement cycle.

Choosing the Right HVAC Size and Type

Manual J Load Calculations

Proper sizing hinges on detailed engineering analysis rather than square-footage estimates alone. Manual J computations factor in insulation R-values, window SHGC ratings, orientation, infiltration rates, and occupant loads. HEP completes a fresh calculation for every replacement to eliminate legacy sizing errors.

Split System vs. Packaged Unit

Tennessee homes often feature split systems with separate indoor furnaces and outdoor condensers. However, certain properties—especially those with limited indoor mechanical rooms or slab-on-grade construction—may benefit from packaged rooftop or ground-mount units. HEP evaluates site constraints and homeowner preferences before making a recommendation.

Heat Pump Considerations

With moderate winter temperatures across much of Tennessee, modern heat pumps paired with auxiliary electric or gas backup heat can offer substantial efficiency gains. Dual-fuel configurations switch to fossil fuel only during extreme cold, maximizing heat-pump operation and lowering annual operating costs.

Home Performance Upgrades That Complement HVAC Replacement

Adding blown-in attic insulation to achieve recommended R-38 to R-60 levels
Sealing and insulating ductwork to reduce leakage and improve static pressure
Installing radiant barriers in high-sun-gain attics
Replacing leaky single-pane windows with low-E double-pane units
Weather-stripping doors and sealing plumbing penetrations to cut infiltration

Addressing these envelope issues during HVAC replacement allows for smaller, more efficient equipment and greater comfort.

Financing, Rebates, and Incentive Opportunities

Utility companies and state energy offices periodically offer rebates for high-efficiency HVAC installations that meet specified SEER, EER, or AFUE thresholds. Federal tax credits may also apply to certain systems with qualifying ratings. HEP stays informed on current programs and guides homeowners through paperwork, ensuring maximum incentive capture and smoother project budgeting.

The Long-Term Value of Expert HVAC Replacement

Replacing an HVAC unit represents a significant home upgrade, but when executed with precision and foresight, it delivers returns beyond comfort alone. Benefits accumulate in multiple dimensions:

Markedly lower monthly energy bills
Healthier indoor air through superior filtration and balanced humidity
Reliable operation that prevents unexpected breakdowns
Increased resale value due to documented efficiency improvements and transferable warranties
Environmental responsibility through reduced carbon emissions and ozone-safe refrigerants

HEP’s comprehensive approach—from meticulous load calculations to post-installation commissioning—ensures every Tennessee homeowner enjoys these tangible advantages. By integrating advanced technology with proven craftsmanship, HEP turns what might have been a reactive equipment swap into a forward-thinking investment in long-term home performance.
