Common Questions
Before you call.
What’s the fastest way to reach you?
Call 865.765.8946. A real person answers 24 hours a day, seven days a week — including nights, weekends, and holidays. For non-urgent scheduling, the booking form on this page works well and we’ll follow up to confirm a time.
What counts as an emergency?
Water you can’t stop, no water at all, sewage backing up into the house, a burst or frozen pipe, gas odor, or total loss of hot water in cold weather. Call rather than filling out a form for any of those.
Can I stop by your shop?
We’re at 3414 Henson Rd C, Knoxville, TN 37921. Our technicians are on the road most of the day, so call ahead if you need to speak with someone in person — it saves you a trip.
How soon can someone come out?
Same-day appointments are often available, especially if you call early. Emergencies are dispatched immediately. When you call we’ll give you a realistic window rather than a window we know we’ll miss.
Do you charge for estimates?
Replacement and installation estimates are free. For diagnostic service calls, we quote a flat rate before beginning any work so you always know the number in advance. Home Club members have the diagnostic fee waived.
What if I’m outside your service area?
Call and ask — it takes one sentence to find out. We serve everything within 25 miles of Knoxville, and if you’re outside it we’ll say so rather than sending someone on a long drive.
