Building a new home

Prior to buying our new home, my hubby and I hired a local Heating, Ventilation, and A/C professional to inspect and analyze the heating and cooling system.  The professional assured us that all components were in great really working order. Once the people I was with and I moved in, my hubby and I started a large renovation project.  The house is severely old, and unquestionably few updates had been completed over the last fifty years. There was insufficient insulation in the walls and the electrical wires were not up to code.  The plumbing system was terribly corroded, and all of the windows needed to be updated. The two of us were relieved that the duct system was in wonderful condition. My hubby gutted the walls and ceilings down to the bare studs and refinished all of the hardwood floors.  Although the outside temperature was rather warm and humid, the people I was with and I didn’t dare run the air conditioning because of all of the dust. The two of us instead opened the windows for ventilation. Once the project was finally complete, the people I was with and I were uneasy to clean up, lower the control unit, and get some relief from the heat and humidity.  The cooling system ran for approximately twenty hours before it quit. When my hubby checked the air filter, he found it really clogged with dust and debris. Cleaning the filter, however, didn’t fix the problem. The two of us were forced to call the Heating, Ventilation, and A/C company back for a repair. He told us that the construction dust had infiltration the cooling unit through the supply and return vents, blocking airflow and leading to the malfunction.   He requested that for future projects, the people I was with and I make sure to seal off the duct system entirely.
