FAQs
How do I know when it’s time to replace my HVAC unit rather than repair it?
Most systems are designed to last 10–15 years. If your unit is approaching or beyond that age, requires frequent repairs, suffers declining efficiency, or uses the discontinued R-22 refrigerant, replacement is usually more cost-effective. Our certified technicians can perform a detailed assessment in your Karns home to help you decide.
What types of HVAC systems do you install in Karns, and are they energy-efficient?
We install high-efficiency heat pumps, air conditioners, gas furnaces, and dual-fuel systems from leading brands such as Trane, Carrier, and Lennox. All equipment meets or exceeds ENERGY STAR® criteria, and we size each system using Manual J load calculations to ensure maximum efficiency and comfort in the Karns climate.
How long does a typical HVAC replacement take from start to finish?
From the initial onsite evaluation to final system start-up, most straightforward replacements are completed in one day. Complex jobs that involve ductwork modifications, zoning, or electrical upgrades may take two to three days. We schedule permitting and inspections with Knox County so you don’t have to worry about the paperwork.
What warranties and guarantees come with a new HVAC installation?
All systems include a 10-year manufacturer’s parts warranty (registration required) and our own 12-month labor warranty. We also offer optional extended labor protection plans up to 10 years. In addition, every installation receives our 100% Satisfaction Guarantee—if you’re not happy within the first year, we’ll make it right at no additional cost.
Will replacing my HVAC unit lower my utility bills, and if so, by how much?
Yes. Upgrading from a 10 SEER system to a modern 16–18 SEER unit can cut cooling costs by 30–40%. Heat pump replacements with HSPF ratings above 9.0 may reduce heating expenses by a similar percentage. Our technicians can provide a personalized energy-savings projection based on your current bills and the specific equipment you choose.
Do you offer financing or rebates for HVAC replacements?
Absolutely. We partner with several lenders to provide low-monthly-payment and 0% APR promotional financing options (with approved credit). Our team also processes TVA’s EnergyRight® rebates, manufacturer incentives, and any applicable federal tax credits for high-efficiency equipment, helping Karns homeowners reduce out-of-pocket costs.
