We have a contract with them. They came in the spring to check. We just do that. There have been no problems with the checkup. They did install, it has been a few years ago, our new heater. They installed our new air conditioner whenever we got a new air conditioner.

I have been using them for a number of years. Their pricing is competitive with anybody else’s. They charge around $90 for cleaning, but they put that in with the oil that they deliver or any service that they do as we are on a budget plan with them, so everything is combined.
