He says that the main thing that has helped him keep the same furnace and A/C unit for so long is the fact that he uses HEPA filters every single time that he needs to change out the air filters.
My dad has always sworn by HEPA filters, and he says that they are always worth the money that you have to spend for them. HEPA air filters are usually more expensive than other types of air filters, but he says that’s because they are the best. I guess he’s probably right, because he was buying air filters for the heating and cooling system in his house long before I was ever born. My dad always brags about the fact that his heating and cooling system is older than I am and that it has been in his house since the day that they built it. I guess he has really taken good care of the HVAC system in the house. He says that the main thing that has helped him keep the same furnace and A/C unit for so long is the fact that he uses HEPA filters every single time that he needs to change out the air filters. I guess my dad probably knows what he’s talking about, but once in a while I just buy a cheap air filter for my house simply because they are less expensive and they are easy to come by. One day my dad was at my house and he took a look at my HVAC system. Whenever he saw the cheap air filter and the fact that I had not purchased a HEPA filter, he just looked at me and shook his head slowly. He was so disappointed that I hadn’t purchased a HEPA filter! I’ll probably do it from now on, just to make him happy.
