Harry as well as I recently fixed up our home, but when Harry and I were almost finished with the second bathroom, I noticed that the a/c system kept running all of the time. The temperature control was set at 74 degrees, but the temperature never went down lower than 72 degrees; I phoned our Heating, Ventilation as well as A/Business as well as scheduled a proper service visit. We believed, perhaps with all the debris from the new construction, that maybe our cooling system just had to have a good cleaning. When our a/c system serviceman arrived, she cleaned as well as looked over our Heating, Ventilation as well as A/C device. The Heating, Ventilation as well as A/C man said that our a/c component was working just great! The HVAC professional expressed concerns about the air duct in the upper floor. I told him that during the recent fixing up task in the dining room, Harry and I ended up closing off 1 of the air ducts, due to it wasn’t necessary, then my issue was, when the fixing up corporations removed the drop ceiling with the den air vent, that perhaps they didn’t seal off the duct typically. Harry grabbed a ladder as well as escorted the Heating, Ventilation as well as A/C serviceman to the shed, so he could climb into the upper level to check the air duct! After a few moments, the Heating, Ventilation as well as A/C serviceman came down as well as informed us the concerned news. The guy said that the ducts are outdated as well as falling apart.
