Questions locals ask before they call
Straight answers—so you know what to expect.
My AC quit in the heat—what should I do first?
Check that the thermostat is set to cool, replace a dirty filter if it’s overdue, and confirm the outdoor disconnect is on. If it still won’t cool, call 865-224-3650 during business hours. We’ll help you triage and schedule diagnostics so you’re not guessing in 90° weather.
Will you push me to replace a system that can be repaired?
No. We’ll diagnose the issue, explain repair vs. replace in plain language—including rough trade-offs—and respect your decision. No pressure sales and no mystery fees.
Do heat pumps work through East Tennessee winters?
Modern heat pumps handle our climate well when sized and maintained correctly. We’ll talk through your home, ducts (or ductless zones), and whether a heat pump, furnace, or dual-fuel setup fits how you live.
Can you install a mini-split for a bonus room or addition?
Yes. Ductless mini-splits are a strong fit for rooms that never stay comfortable on the main system. We’ll walk the space, discuss zoning, and install cleanly with proper line-set and drain work.
