I will never use this company again. The service technician was very rude. He shoved a paper in my face telling me he had to put an anchor in my roof and when I asked if it could cause a leak he stated " we use silicone". He gave me a $980 estimate to fix a gas valve. When I told him that he needed to talk to my husband, he rolled his eyes. I gave him his $90 service fee and he left. I changed the filters and my heater started working again. He tried to take me for $960.
