Needed to fix heating part of HVAC. Could not fix it. Said he would come back at some time in the future when and if needed parts arrive from China. Charged me almost $800. This is the last of multiple problems I’ve had with a system I bought from them and that they installed. Had someone else look at it and it appears it was installed incorrectly and can never be fixed as it is. Everyone I talk to is always really nice, including the service technician, but they can’t or won’t fix my HVAC system.
