Anyone who gets proper A/C service will tell you, it easily does make a difference. Whenever I meet a stubborn person who is firm in their belief that a heating plus A/C tune up does nothing for their A/C; I tell them not only our story, but other stories our friends have told myself and others as well. When I was younger, I did not take fantastic care of our heating plus A/C unit at all, however I also did pretty much nothing for it, except maybe change the air filter every more than five months or so… And because of this, I had a ton of problems with it, but I never acquaintanced the concerns I had with our behavior. It wasn’t until I started taking proper care of both our heating plus A/C components that I easily noticed a difference. It was a heating plus cooling professional who gave myself and others the comprehension I needed in order to begin taking proper care of the systems. I started doing a lot more, increasing the air filter properly, getting HEPA filters plus cleaning the unit out myself… But however, I still didn’t get heating plus air conditioning tune ups, plus I still experienced concerns, although less than I used to have. It wasn’t until I started getting annual service did I notice a difference, then there was a sharp decrease in the amount of heating plus air conditioning repair bills I would have to pay, plus our A/C unit started working almost flawlessly… Nowadays, I typically make sure to get service, because it easily does make a difference.
