FAQs
How can replacing my old HVAC system lower my monthly energy bills in Knoxville?
Modern high-efficiency heating and cooling equipment uses variable-speed compressors, ECM blower motors, and advanced refrigerants that deliver the same comfort while consuming 20-40 % less electricity than units manufactured just 10–15 years ago. Because Knoxville’s climate requires both significant summer cooling and winter heating, these efficiency gains translate into noticeable savings on every utility bill. In many cases, homeowners recoup the cost difference between a standard- and high-efficiency unit through lower power bills within 4–7 years.
How do I know it’s time to replace instead of repair my HVAC unit?
Consider replacement when: (1) the system is 10–15 years old; (2) repair estimates exceed 25 % of the price of a new system; (3) your summer or winter bills have risen steadily without a change in usage; (4) comfort problems such as uneven temperatures or excessive humidity persist; and (5) the unit still uses R-22 refrigerant, which is no longer produced and makes repairs costly. A no-cost home evaluation can confirm whether replacement will provide a better long-term value than another repair.
What size HVAC unit is best for my Knoxville home?
Proper sizing is determined through a Manual J load calculation that factors in square footage, insulation levels, window type, orientation, ductwork, and even local weather data for Knoxville. Oversized equipment short-cycles, wastes energy, and creates humidity issues, while undersized systems run constantly and still leave rooms uncomfortable. Our comfort specialists measure your home, analyze the data with ACCA-approved software, and present right-sized options—usually expressed in tons (cooling) and BTUs (heating)—for maximum efficiency and comfort.
Are there rebates, tax credits, or financing programs available for high-efficiency HVAC replacements in Knoxville or Tennessee?
Yes. Tennessee Valley Authority (TVA) and Knoxville Utilities Board (KUB) periodically offer rebates—often $150–$500—for qualifying ENERGY STAR® heat pumps and air conditioners. Federal tax credits under the Inflation Reduction Act currently provide up to $2,000 for high-efficiency heat pumps meeting specific SEER2 and HSPF2 ratings. Low-interest financing through TVA’s eScore program or traditional 0 % promotional financing through our lending partners can spread the cost over 12–60 months, often with monthly payments lower than the energy savings achieved.
How long will HVAC replacement take and will my household be without heating or cooling?
A typical residential change-out in Knoxville takes one full workday—about 6–10 hours. Our crew removes the old equipment, sets the new indoor air handler or furnace, installs the outdoor condenser or heat-pump unit, evacuates and charges the refrigerant lines, and performs start-up testing. Your home is usually without conditioned air for only a few hours, and we schedule installations to minimize downtime. We also place protective runners and clean up thoroughly so you can enjoy immediate comfort.
What maintenance should I perform after installation to keep energy bills low?
1. Replace or clean air filters every 30–90 days. 2. Keep outdoor units free of leaves and debris, maintaining at least 2 ft. of clearance. 3. Schedule professional maintenance each spring (cooling) and fall (heating) to check refrigerant charge, coil cleanliness, electrical connections, and thermostat calibration. 4. Seal and insulate any accessible ductwork to prevent air leaks. 5. Use a programmable or smart thermostat to set back temperatures when you’re away. Consistent maintenance preserves factory efficiency, prevents breakdowns, and ensures your new system delivers the lowest possible monthly energy costs.
