From smart thermostats that learn your schedule to hospital-grade air purifiers integrated directly into your ductwork, we design each system around one goal: healthier living. That’s why we focus on ventilation and air quality as much as temperature control, using high-efficiency filters, humidity management, and whisper-quiet fans to remove allergens and circulate fresh, clean air to every room. Whether you’re upgrading an aging unit or building your dream home, trust HEP to deliver comfort you can feel—and energy savings you’ll notice—season after season.
FAQs
What energy-efficient heating and cooling systems do you recommend for homes and small businesses in Greeneville?
Because Greeneville experiences humid summers and cool winters, we generally recommend high-SEER variable-speed heat pumps, dual-fuel (hybrid) systems that combine a heat pump with a high-efficiency gas furnace, and ENERGY STAR® certified air conditioners rated 16 SEER or higher. For properties with sufficient yard space, geothermal heat pumps can cut energy use by up to 50 percent compared with conventional HVAC equipment. Every recommendation is based on a Manual J load calculation to make sure the system is properly sized for your building envelope and local climate.
How much can I expect to save on utility bills by upgrading to an energy-efficient HVAC system?
Actual savings vary with home size, insulation levels, and existing equipment, but Greeneville customers who replace a 10- to 13-SEER air conditioner with a 16- to 18-SEER model typically see summer electricity costs drop 25 – 35 percent. Swapping an 80 percent AFUE furnace for a 96 percent model can reduce winter heating expenses 15 – 20 percent. If you move to an inverter-driven heat pump or geothermal unit, total annual HVAC savings of 40 percent or more are common. In most cases the payback period ranges from 3 to 7 years, after which the lower operating costs are pure savings.
What are the signs my home’s ventilation isn’t adequate, and how can you help improve it?
Warning signs include persistent indoor humidity above 60 percent, musty odors, condensation on windows, visible mold, or allergy symptoms that improve when you leave the house. Our technicians perform airflow measurements and use blower-door testing to determine how much fresh air your home actually gets. Solutions may include adding powered exhaust fans, installing a whole-house heat-recovery ventilator (HRV) or energy-recovery ventilator (ERV), balancing existing ductwork, and sealing envelope leaks so outdoor air enters through controlled pathways instead of cracks.
Which indoor air quality (IAQ) products work best for Greeneville’s pollen and humidity levels?
For households bothered by spring pollen and year-round humidity, we recommend a layered approach: (1) a high-MERV (11–13) media filter or a hospital-grade HEPA bypass filter to capture particulate allergens; (2) a whole-home dehumidifier integrated into the duct system to maintain 45 percent relative humidity; (3) optional UV-C lamps or a photocatalytic air purifier to neutralize mold spores and bioaerosols on cooling coils; and (4) an HRV/ERV to supply fresh air without a large energy penalty. All devices are selected to match your HVAC system’s airflow so static pressure stays within manufacturer limits.
Are there rebates, tax credits, or financing programs available for energy-efficient HVAC upgrades in Greeneville?
Yes. Through the TVA EnergyRight® program, Greeneville Light & Power customers can earn rebates—currently up to $150 per ton—for qualifying high-efficiency heat pumps and new duct systems. The federal Energy Efficient Home Improvement Tax Credit (25C) provides up to 30 percent of installed costs (capped at $2,000) for heat pumps, and $600 each for furnaces, central ACs, and advanced air sealing/insulation. Many equipment manufacturers offer seasonal rebates, and we partner with lenders that provide 0–9.99 percent APR financing so you can spread the cost while you start saving on utilities immediately.
How often should I schedule maintenance to keep my high-efficiency HVAC system operating at peak performance?
We suggest two professional tune-ups per year: one in early spring for cooling components and one in early fall for heating. Our maintenance checklist includes cleaning condenser and evaporator coils, checking refrigerant charge, calibrating thermostats, testing safety controls, lubricating motors, and verifying static pressure across filters. Regular service maintains efficiency, protects your manufacturer’s warranty, and helps the system reach its expected 15- to 20-year life span. Between visits, replace or clean filters every 30–90 days and keep outdoor units free of leaves and grass clippings.
