Do not trust the owner of Tempco.
This guy gave me on price, then wrote it up differently later. He charged me for an air cleaner which I never requested and he never installed. It was only when I complained to the finance company and they stepped in that he agreed to remove the charge. He avoided my phone calls constantly.
The furnace they installed worked, but the air conditioning was a complete disaster! He kept promising to come over and fix it, I took off work to wait for him and then... no call, no show. Check the BBB. They have a file a mile long on him.
And that "Liz" person that answers the phone is his WIFE. She pretends like she can't get a hold of him, but she doesn't tell you that she goes home with him every day.
