FAQs

How do I know it’s time to replace my HVAC unit instead of repairing it?

If your system is more than 10–15 years old, needs frequent or costly repairs, struggles to maintain set temperatures, causes unusually high energy bills, or still uses R-22 refrigerant, a replacement is usually more economical. Our certified technicians will perform a full inspection and cost-benefit analysis so you can make an informed decision.

What kinds of HVAC systems do you install, and which works best for Knoxville’s climate?

We install high-efficiency split heat pumps, gas furnaces with central air, dual-fuel (hybrid) systems, and ductless mini-splits. Because Knoxville experiences both humid summers and cool winters, many homeowners choose variable-speed heat pumps or dual-fuel systems for year-round comfort and lower utility costs. We size every unit with Manual J load calculations to match your home’s exact needs.

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

A typical residential replacement takes 4–8 hours from arrival to final commissioning. Your system will be offline during that window, but we schedule installs first thing in the morning, use temporary cooling/heating solutions if needed, and always verify full operation before we leave, so downtime is minimal.

Are your technicians certified and licensed to perform HVAC replacements in Tennessee?

Yes. All lead installers are NATE-certified, EPA-licensed for refrigerant handling, and fully insured. Our company holds a Tennessee Mechanical Contractor’s license, meets Knoxville/Knox County permitting requirements, and passes mandatory city inspections on every replacement job.

What does a new HVAC system cost in Knoxville, and do you offer financing or rebates?

Pricing varies by size, efficiency rating, and installation complexity, but most full system replacements range from $6,500 to $12,000 installed. We partner with major lenders for 0% APR promotional financing (with approved credit), accept TVA EnergyRight rebates, and can guide you through any manufacturer or federal tax incentives available at the time of purchase.

Will a new HVAC unit really lower my energy bills, and how quickly will it pay for itself?

Modern systems rated 16–20 SEER2 and 9–10 HSPF can cut heating and cooling costs by 25–40% compared to equipment installed 15 years ago. In Knoxville’s mixed climate, most homeowners see monthly savings of $40–$100, allowing a typical payback period of 5–8 years, plus improved comfort, quieter operation, and a manufacturer parts warranty of up to 10 years when registered.
