FAQ

Questions we get asked most.

If yours isn't here, call and ask. Someone picks up.

Are your technicians licensed and insured?

Yes. HVAC work runs under Ohio license #37179 and plumbing under #13557, both insured. Every tech is drug-tested and background-checked before they set foot in your house.

Do you offer free estimates?

Yes, on system replacements, new installations and major repair work. A diagnostic visit on a system that has already failed is a service call rather than an estimate, and you hear that price before we come out.

Do you offer financing options?

Yes, on qualifying equipment and repair work. The lender sets the rate and the term, so what you're offered depends on your credit rather than on us. Applying takes a few minutes and does not commit you to the work.

Which areas do you serve?

Dayton, Cincinnati, Troy, Tipp City and the Miami Valley communities around them, out of four offices. If you're not sure whether your town is in range, check the locations page or just call and ask.
