FAQs
Why should I replace my older HVAC system with a high-efficiency unit in Tullahoma?
Tullahoma’s hot, humid summers and chilly winters force HVAC equipment to run almost year-round. Older 8–12 SEER systems waste energy, struggle with humidity removal, and often rely on phased-out R-22 refrigerant. A modern high-efficiency heat pump or gas furnace/AC combo (15–20 SEER2 and 8.8–10 HSPF2) can cut energy use up to 40 %, improve indoor comfort, reduce humidity swings, and qualify for stronger manufacturer warranties. Replacing now also protects you from costly repairs and refrigerant price spikes.
What efficiency rating should I look for under the new 2023 DOE standards?
As of 2023, Tennessee (DOE South Region) requires a minimum of 14.3 SEER2 for split air conditioners and 15.0 SEER2/7.8 HSPF2 for heat pumps. For the best long-term value we recommend: • 16–18 SEER2 air conditioners with variable-speed indoor blowers. • 9–10 HSPF2 heat pumps with inverter compressors for superior part-load efficiency. • 95 %+ AFUE gas furnaces if you have natural gas service. These ratings balance upfront cost with energy savings over the 15- to 20-year life of the equipment.
How much can I expect to save on my utility bills after upgrading?
Savings depend on the age and condition of your current system, home insulation, and thermostat settings, but most Tullahoma homeowners moving from a 10 SEER unit to a 16 SEER2 system see electricity costs drop 25–40 %. With TVA’s average residential rate of about 12 ¢/kWh, that often translates to $300–$600 in annual savings for a 2,000 sq ft home. Higher HSPF2 heat pumps can also reduce or eliminate winter auxiliary heat strip usage, delivering additional cold-weather savings.
Are there rebates, tax credits, or financing options available in Tullahoma?
Yes. • Federal Inflation Reduction Act (IRA) 25C tax credit: up to 30 % of the installed cost, capped at $2,000 for qualifying heat pumps or $600 for high-efficiency ACs/furnaces. • TVA EnergyRight home energy rebate: typically $150–$400 for qualifying heat pumps or dual-fuel systems (amount varies by efficiency tier). • Tullahoma Utilities Authority (TUA) on-bill financing: 6- or 10-year low-interest loans that let you pay for your new equipment through your electric bill. • Manufacturer seasonal promotions: Lennox, Trane, Rheem, and others often offer instant rebates or 0 % APR financing. Our team handles all paperwork and will apply eligible incentives to lower your out-of-pocket cost.
How long does HVAC replacement take and will I be without heating or cooling?
A standard like-for-like replacement usually takes one full day (6–10 hours). Complex jobs involving duct modifications, attic platforms, or line-set reroutes can take two days. You’ll be without heating or cooling only while we disconnect the old unit and commission the new one—typically 4–6 hours. We schedule work around weather forecasts and provide temporary heaters or window units if an overnight gap is unavoidable.
What maintenance is required to keep my new high-efficiency system running at peak performance?
High-efficiency equipment relies on clean airflow and precise refrigerant charge. Follow these guidelines: • Replace or wash filters every 30–90 days. • Keep outdoor coils free of leaves, grass clippings, and debris. • Schedule professional tune-ups twice a year—spring for cooling, fall for heating. • Enroll in our ComfortGuard Maintenance Plan, which includes biannual inspections, priority service, filter reminders, and a 15 % repair discount. Proper maintenance maintains efficiency, preserves warranties, and can add 3–5 years to system life.
