My husband and I recently remodeled our home. When we were almost finished with the guest bathroom, I noticed that the air conditioner kept running all day. The thermostat was set at 75 degrees, but the inside temperature never went below 79 degrees. I called my HVAC supplier and scheduled a regular maintenance visit. We thought, perhaps with all the dust from the recent construction, that maybe our air conditioner just needed a good cleaning. When our air conditioner technician came, he cleaned and checked our HVAC system. The HVAC technician said that our air conditioning unit was working fine. He expressed concerns about the ductwork in the attic. I told him that during the recent remodeling job in the kitchen, we ended up closing off one of the air ducts, because it wasn’t necessary. My concern was, when the remodeling contractors removed the drop ceiling with the kitchen air vent, that maybe they didn’t seal off the duct properly. My husband grabbed a ladder and escorted our HVAC technician to the garage, so he could climb into the attic to check the ductwork. After a few minutes, the HVAC technician came down and gave us the sad news. He said that the ducts are old and falling apart. I told him that we are not surprised, because the house was built in 1975, and the air ducts were never replaced. He said that the kitchen air duct was closed off properly, but the rest of the ductwork was collapsing and preventing efficient air flow. We decided to get all new ductwork. The airflow is balanced better throughout the house now. We couldn’t be happier with the results.
