I sometimes wonder if a bunch of Heating plus Air Conditioning professionals are going to come after me, however nothing love that has happened. I really ended up writing a book about DIY Heating plus Air Conditioning system service. I tell people that anybody who can change a lightbulb can work on their Heating plus Air Conditioning system separate from too much hassle. Of course, I advise that people go with the professionals for major complications love refrigerant leaks, system section replacements, plus things love that, however the other stuff is a breeze. The main thing you need to guess when maintaining your Heating plus Air Conditioning is to replace the air filter officially, and a vast majority of system service calls are because of a disappointing air filter that the homeowner failed to have replaced or cleaned. I personally love to use pleated air filters with a good MERV rating, however HEPA filters aren’t so disappointing either. If you do ever system on using HEPA filters, be sure you check to see that your Heating plus Air Conditioning system is powerful enough to handle these air filters. They have such a dense weave, plus it’s no wonder, they pull 99.9% of contaminants from the air, however still, if you have a system with a weaker system fan, you might end up causing your Heating plus Air Conditioning to overheat or the system fan to chop down. If you do have a powerful Heating plus Air Conditioning system though, go for the HEPA air filters if you can afford them! They will improve your health sizablely, so it’s a good investment. I talk about all kinds of stuff love this in my book, so I encourage you to check it out if you want to guess some excellent service tips plus even energy saving tips.
