FAQs

What does it mean that your technicians are NATE-certified?

NATE (North American Technician Excellence) certification is the HVAC industry’s most respected credential. Passing the NATE exams shows our technicians have proven, up-to-date knowledge in heating, air-conditioning, and refrigeration. For you, that translates to fewer installation errors, a properly sized and calibrated system, better energy efficiency, and warranty protection that will stand up if you ever need a manufacturer claim.

How can I tell when it’s time to replace my HVAC unit instead of repairing it?

In Greeneville’s four-season climate, most heat pumps and furnaces last 12–15 years and central air conditioners about 10–12 years. Consider replacement if: (1) your unit is near or past this age, (2) energy bills or repair costs keep climbing, (3) rooms heat or cool unevenly, (4) the system still uses R-22 refrigerant, or (5) the repair quote exceeds roughly 30% of a new system’s cost. Our techs can run a cost-of-ownership comparison so you can make an informed choice.

What brands and sizes of HVAC equipment do you install?

As an independent contractor, we size equipment based on Manual J load calculations for each home, not on guesswork or square-foot rules of thumb. We install ENERGY STAR® models from Trane, Rheem, Goodman, Mitsubishi, and Daikin in capacities from 1.5 to 5 tons for split systems and 40,000–120,000 BTU for gas furnaces. We’ll explain SEER2, HSPF2, and AFUE ratings so you can balance upfront cost with long-term energy savings.

How long does an HVAC replacement take, and will I be without heat or AC during the process?

Most standard change-outs are completed in one working day—typically 6–8 hours. Our crew protects floors, removes the old unit, sets the new indoor and outdoor components, installs new refrigerant lines or flue pipes if needed, charges the system, and tests every safety control. You will be without heating or cooling only during the physical swap, usually a few hours. For extensive duct modifications or dual-fuel conversions, the project can extend to a second day; if that’s the case, we provide temporary space heaters or portable AC units at no charge.

Are there rebates, tax credits, or financing options available in Greeneville?

Yes. TVA’s EnergyRight program currently offers rebates up to $400 for qualifying high-efficiency heat pumps. Federal tax credits under the Inflation Reduction Act provide up to $2,000 for heat pumps and 30% of cost (capped amounts) for qualifying furnaces or air conditioners installed in 2024. We partner with local credit unions and Synchrony Bank to offer 0% APR plans for 18 months or low fixed APR loans up to 120 months. Our office handles the paperwork so you don’t miss a single incentive.

What kind of warranty and maintenance do you provide after installation?

All new systems include a 10-year manufacturer parts warranty and a one-year labor warranty. Registering the equipment within 60 days can extend parts coverage to 12 years on select models—our staff files that registration for you. We also include your first year of preventive maintenance at no charge, which covers a spring AC tune-up and a fall furnace or heat-pump inspection. Ongoing Comfort Club memberships lock in priority service, seasonal tune-ups, and 15% off any future repairs to keep your new system running efficiently for decades.
