There are several signs that it might be time for you to consider having a maintenance appointment performed on the HVAC system.
One of the biggest signs that trouble is on the way is a high electric bill.
When your energy bill is higher than usual, there may be problems with the HVAC system. Most of the time during the summer, the electric bill for my home is around $400. I have a 2500 ft house with an in-ground pool. The pool is not heated. If it was, I could spend another $100 every month on the energy bill. This month I received the energy bill and it was $625. There was absolutely no reason for the energy bill to be that high. We didn’t do anything different this month than the previous month and temperatures were regularly the same. When I received the higher than average utility bill, I immediately contacted a local HVAC supercenter to schedule a maintenance appointment. I told the lady on the phone that I was concerned about the higher energy bill that I received and she told me that it was a very good idea to call them for help. They could perform routine and proper maintenance on the whole system and find out if anything seemed out of the ordinary. It didn’t cost very much money for the maintenance appointment. In fact, I found a coupon on the website which entitled me to save $30 on the price. After the service appointment, I found out that the ductwork was the problem. I need several spots sealed and repaired.
