After my sister told me how some incompetent servicemen messed her unit up, I knew that finding a quality specialist is a difficult but worthy task.
Last spring I noticed that my Heating and Air Conditioning unit had started acting up.
It would be intermittent in airing the home and sometimes I could tell that the air was not fresh. It decreased the quality of indoor air. After consulting my neighbors, I found a good and legitimate local business that had a qualified cooling system workman that did quality a/c service. I held my breath hoping that the job they would do would be quality work, however when they came to my premises, I asked for identification and proof of certification before they started the air conditioner repair service, one of the air conditioner workers would constantly tell me the next step they were taking and explain the importance of the step. I got to know that replacing the filters increased the indoor air quality. I could tell that the specialist knew more about air conditioning and they also knew how to operate, maintain and service problems with a ductless multi-split unit. Once they were done with the air conditioner service, the unit was as good as a new air conditioner unit. It functioned as a new commercial air conditioner at the office. I could tell that these experts had done numerous air conditioner installations as they were absolutely meticulous at their task, however they advised me to get a new stock of filters from the air conditioner business! Finally, they recommended I update the dial thermostat to one which was more modern like the programmable regulator.
