My house was built 5 years ago. From the day I moved in the AC never seemed like it cooled our house and our power bills were extremely high. PG&E was couldn't explain why our bill was so high.
In the last four years we have had to replace our blower motor and the run capacitor twice. We also had a problem with the drain pan filling with water. Well this week it was discovered the evaporator was installed backwards. The arrow on the evaporator points towards the furnace, instead of the duct work. I had an HVAC person out who confirmed it was installed backwards by the builders AC sub.
I have many questions that I am hoping some of you can answer. Does this explain why my power bills have been so high? Does it explain why I have had so many problems in such a short period of time with my AC unit? Because the evaporator has been installed backwards for the last 5 years is there any chance there is damage or strain on the rest of my system? Should I have the AC company replace any other parts when they fix the evaporator? Thanks for your time.
