My husband had been planning his work trip for a week now. He had just received word that he would be flying to the capital to oversee the grand opening of their new branch. Tom would also be signing a significant contract with some investors. We were both happy about the trip as it would open many doors and opportunities for Tom. The eve before he left, we noticed that the sounds from the HVAC system had gotten louder and remained consistent. The digital thermostat was also acting up. My husband checked the batteries and confirmed they had juice left. Tom would oversee the biannual heating maintenance, but since he would be going, he helped me contact the air conditioning company and schedule quality AC service for two days later. The call to the home and commercial air conditioning company did not go through at the time, so I had to try later, which I did. After dropping my husband off at the airport, I rushed home and found the air conditioning technician waiting at the gate. I directed the air conditioning professional to the electric heat pump and started by checking the ductwork; the vents were filthy and had leaks. They redid the duct sealing and replaced some worn-out components, such as the AC filter, which was beyond cleaning. The cooling expert replaced it with a HEPA filter to help improve the air quality, which was in deplorable condition and also fixed the regulator. When he finished, the a/c setup was as good as new. It was a good learning experience for me, and I was glad they restored the indoor comfort by the afternoon.
