We’ve Got You Covered

Our factory trained technicians at Key service all brands of equipment. Whether your home heating and cooling system needs a repair, cleaning or a tune-up, we are here to help keep you safe.

We use a flat-rate pricing system that takes the guesswork out of your bill. Our pricing includes up-front quotes for repair fees, including parts & labor. That way you’ll know the price of your repair before the technician starts work.  S&E Members take advantage of 15% parts and labor for any repairs that may be necessary.  

If the repair takes longer than expected, we will stand by our quote and we guarantee you won’t pay more. Our flat-rate pricing is designed to protect you, the homeowner, from unexpected costs.
