I was delivering cooling equipment to a home far from town. The house was in an area where children required bikes to visit their neighbors since it was quite a distance to get to the next neighbor. The homeowner had called the cooling company seeking to install a smart HVAC unit. The installation team was right behind me since it was a one-day job. Even though the climate control system had one of the best air purification help, the client said they also wanted a whole-home air purification unit. Mary and Marvin, the homeowners, had previously had a problem with indoor air quality and decided not to take a chance on the matter. By regularly replacing the air filter, they would still have good air quality, but since they wanted to turn it up a notch, we had no reason not to comply. Evidently, the equipment was essential to them, and with an asthmatic grandchild, no one could blame them for being too cautious. Before the installation, the cooling technician had to make sure that everything was okay with the ductwork and duct cleaning was done. The house was big, so we all had to finish the a/c set up on time. The first time I saw the house, I thought that the cooling expert had bitten more than he could chew when he assured the owner it was a job to be finished by the end of the day, but it turned out he was correct. We advised the homeowners when to call a cooling specialist for HVAC maintenance. We also added that with regular a/c service, they would rarely need to call for repair. It also helped that their air conditioner utilized the latest cooling technology.
