Edison Heating and Cooling have been taking care of my HVAC system for about seven years now. They did the original installation, and it went great. They even moved the system for us for free. We had it installed too close to our bedroom, and it was very loud at night. We gave Edison Heating and Cooling a call and they came and moved it. Since that time we have had a maintenance contract with them to keep our system in good working order. Joe Perry is fantastic. He is very responsive when we call them to come out. He always calls the night before they come out, and he calls again about 1/2 hour before they arrive. I think that is going the extra mile. I highly recommend using them. They stand behind everything they do. I have had nothing but good experiences with them. Fantastic customer service is how they operate their business.
