AFG Heating and Cooling

I had these guys come out to look at my air conditioner (just bought the house in winter so could not check whether it worked during home inspection). Prior to the visit I had someone else look at it and recommend replacing two parts as a result and it still did not work. When AFG came out to take a look (I chose them based on the Homestars rating), he took a look at the furnace and told us the circuit board on the furnace was not working and he tried bypassing the board to double check. He told us the board needs to be replaced ($600-800) or replace the whole furnace ($3000+). The furnace was original to the house (circa 1970s) and so it made no sense to replace the board at that cost.
We decided to shop around for a furnace and found one on promotion from another business rated highly on Homestars and they gave us a deal for both the furnace and ac. Long story short, when the guys were installing the new units, they took a look at the thermostat and said it was not wired properly and the ac/furnace could have worked for all they know.
AFG did not even take a look at the thermostat and rushed through the service call which you pay by the hour. Had he taken his time and checked the thermostat, we likely could have gotten another year or two out of both units.
I could not really afford replacing them in the first place but the temperature has been feeling like 35+ for several weeks and we have a northern breed dog who does not fare well in the heat so had to do something fast.
I would not recommend this company.
