They have the most horrible customer service. We called to schedule our furnace to be cleaned. We were told a tech would be at our house "sometime after 1". I took time off from work to WAIT for someone to show up SOMETIME AFTER ONE..at 3:00 we got a call that there was an emergency and we would need to reschedule. I reschedule for the next Friday and asked for an exact time seeing I will have to leave work again for this and I asked for as late in the day as possible. I was told a tech would be at our house on that following Friday AT 2PM. I was told that 2:00 is the latest they schedule. I had to get our of work early AGAIN to wait for them. At 230 I called to find out where the tech was and a little witch named Amy answered the phone. Amy should lose her job. I was told a tech would be at my house in about an hour..unacceptable but now I missed more time for them, so fine. At 300, they called to cancel. Horrible horrible company.. couldn't care less about their customers.
