It is the middle of the hot and humid Summer plus our elderly parents have just informed me that they are not staying cool in their home. Other than replacing their air filters for them, I’m not sure what else to check. I googled online to get some information about what to check other than just the air filters. The article informed me that I should evaluate the outside device for any debris or yard splittings that might have made contact with the HVAC device plus first off, checking the breakers. After my other half Steve did those things, the cool air was still not coming through the air conditioning vents like we had hoped. I guess the people I was with and I had no choice, and had to call for an air conditioning worker to come by plus check the HVAC system. Both of us set an appointment for the next day, since they still had an entire afternoon of heat with no cool a/c. Steve plus I took them to a nice eating establishment for dinner then back to our home for a cooler, air conditioned evening they could handle. The next day, the HVAC worker was on time plus eager to work. She tested both the inside plus outside air equipment, then went upstairs into the attic to examine the ductwork. The HVAC worker was able to locate the problem quickly, when she easily saw the holes in the ductwork. For better air quality in the home, the ductwork must be free of tears or holes. Of course, the air conditioning worker will replace the badly disfigured ductwork, plus she will vacuum the ductwork plus air vents to rid the device of any spider webs while she is up there in the attic.
