FAQs

What makes a new HVAC system “high-efficiency” and why is it important for homes in Harriman?

A high-efficiency system is built with advanced compressors, variable-speed blowers, and superior heat-exchange components that achieve a Seasonal Energy Efficiency Ratio (SEER2) of 15.2 or higher for cooling and an Annual Fuel Utilization Efficiency (AFUE) of 95 % or better for furnaces. Because Harriman experiences hot, humid summers and cool winters, these systems reduce run time, control humidity more precisely, and can lower annual heating-and-cooling costs by 20–40 % compared to mid-efficiency units.

How much can I expect to save on utility bills after replacing my older unit with a high-efficiency model?

Savings depend on your current unit’s age and efficiency, home insulation, and thermostat habits, but most Harriman homeowners see $450–$900 in annual electricity and gas savings. Over a 15-year lifespan, that can translate into $6,000–$12,000, often offsetting the higher upfront price of the equipment.

How long does an HVAC replacement usually take and will my home be without heating or cooling during the process?

A standard residential replacement—including removal of the old equipment, installation of the new indoor air handler or furnace, outdoor condenser/heat pump, refrigerant lines, thermostat, and start-up testing—typically takes one full workday (6–10 hours). Your system will be offline during that window, but we schedule installations when weather is mild whenever possible and bring temporary heaters or portable A/C units if extreme temperatures are expected.

Are there any rebates, tax credits, or local incentives available for high-efficiency HVAC installations in Harriman?

Yes. Through 2032, the federal Inflation Reduction Act offers a 30 % tax credit (up to $2,000) on qualifying heat pumps and a $600 credit for high-efficiency air conditioners or gas furnaces. Harriman customers served by TVA’s EnergyRight® program may also earn rebates of $200–$800 depending on SEER2/AFUE ratings. We handle all paperwork and provide the AHRI certificate you’ll need for submissions.

How do I know what size (tonnage or BTU) system my house actually needs?

Proper sizing requires a Manual J load calculation that considers square footage, insulation values, window types, orientation, and local climate data for Harriman. Oversized units short-cycle and waste energy; undersized units run continuously and wear out faster. Our comfort specialist performs a room-by-room assessment with software to recommend the ideal capacity—often 1 ½–5 tons for most area homes.

Do you offer financing or extended warranties for new high-efficiency HVAC systems?

Absolutely. We partner with several lenders to provide low-interest and zero-interest promotional financing options, some with no money down and terms up to 120 months. Every system comes with a 10-year parts warranty and one-year labor warranty, and optional extended labor coverage up to 12 years is available for extra peace of mind.
