Anyone who gets respected a/c maintenance will tell you, it absolutely does make a difference.
Whenever I meet a stubborn person who is firm in their belief that a heating in addition to a/c tune up does nothing for their cooling system, I tell them not only our story, but other stories our friends have told me as well. When I was younger, I did not take fantastic care of our heating, ventilation, and A/C unit at all! I did pretty much nothing for it, except maybe change the air filter every several weeks or so! Because of this, I had a ton of problems with it, although I never associated the issues I had with our behavior. It wasn’t until I started taking correct care of both our heating, ventilation, in addition to the A/C device that I genuinely noticed a difference. It was a heating in addition to a cooling professional who gave me the knowledge I needed in order to start taking correct care of the systems. I started doing a lot more, increasing out the air filter respectfully, getting HEPA filters in addition to cleaning the unit out myself; however, I still didn’t get heating in addition to A/C tune ups, in addition to I still experienced issues, although less than I used to have. It wasn’t until I started getting annual maintenance did I notice a difference, and there was a sharp decrease in the amount of heating in addition to A/C service bills I would have to pay… In addition, our air conditioning unit started working almost flawlessly; but nowadays, I always make sure to get maintenance, because it absolutely does make a difference.
