I was back on the drawing board a second time that year. At the beginning of the year, I had done extensive research on the type of air conditioner I needed. One, I had undergone numerous a/c repairs, and when the a/c worker told me it was time to get a new air conditioning installed, I was not surprised. Sometime in September, a friend asked me to go with her to the air conditioning company to help her choose new HVAC equipment. I took the opportunity to buy a new a/c filter because I had not changed it in a while. We talked to an a/c representative who advised us, and by the end of the session, my friend had a clear vision of what she wanted. She was even excited to get a thermostat, which she was never on board with because she did not see the need to get an intelligent regulator when the analog one was still working. I also compared their a/c care plan with the one from my air conditioning supplier. I was pleasantly surprised to find out that the local air conditioning business had a variety of a/c services. Since they were close to our home, I would be contacting them for a/c repair and a/c care. They did an excellent job installing her system, and they were meticulous and skillful and would readily recommend their services, including air conditioning maintenance. My neighbor ended up getting a similar HVAC system to my one, and we were now both enjoying good indoor air quality and comfort.
