My dad basically always called himself “a jack of all trades, a master of none” which was a colorful way of saying he knew a little about a lot of things, however didn’t really know a lot about anything! Now that I am grown, with a family of my own, I have found myself using that expression quite a bit. Having a family means you have to actually know a lot of different things about managing a property, which is a heck of balancing act if you ask me. I would not call myself a plumber, however I really do know how to unclog a drain. I would similarly not call myself a Heating plus Air Conditioning equipment expert, however I do know enough to repair my personal HVAC equipment whenever there is a bit of a problem. I have found over the years that regular Heating plus Air Conditioning equipment maintenance will prevent 90% of all the future problems with the equipment. It is the nature of an air conditioner to circulate the air inside your property, constantly passing it through vents, air duct, plus the central air filter before going back into the property. After hundreds of cycles, all the tiny bits of hair, dust, plus skin cells in the air start to collect in the air filter, plus also on the sides of the air ducts. The more this builds up, the harder the AC equipment has to task to keep the air circulating… Something as self-explanatory plus easy as changing the air filter on a strict schedule can add years to the life of your Heating plus Air Conditioning equipment! It’s also great to clean the air duct every other year at least.
