Anyone who gets regular cooling system maintenance will tell you, it really does make a difference. Whenever I meet a stubborn lady who is firm in their belief that a heating and cooling system tune up does nothing for their a/c, 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 great care of our heating and cooling system unit at all, but I did pretty much nothing for it, except maybe change the air filter every six weeks or so… Because of this, I had a ton of complications with it, but I never associated the issues I had with our behavior. It wasn’t until I started taking respected care of both our heating and cooling system components that I really observed a difference. It was a heating and cooling professional who provided me the knowledge I needed in order to start taking respected care of the systems. I started doing a lot more, adjusting the air filter properly, getting HEPA filters and cleaning the unit out myself, but however, I still didn’t get heating, ventilation and A/C tune ups, and 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, but there was a sharp decrease in the amount of heating, ventilation and A/C maintenance bills I would have to pay, and our cooling system unit started working almost flawlessly! Nowadays, I consistently make sure to get maintenance, because it very does make a difference.
