Did you ever know that 30 seconds of your time could actually save you thousands of dollars in the long run? I am sure you have no idea in the world what I am talking about. But let me tell you, that 30 seconds of your time to change the air filter of your central heating and air conditioning system unit could save you from having to spend thousands of dollars investing in a brand new HVAC system! Air filter changing is something many of us hate and sometimes forget to do. But think of this…if you do not change your air filter of your central heating and air conditioning system at least once every few months, you are making your central heating and air conditioning system run and work overtime. And the more your central heating and air conditioning system runs and works overtime, the more you are running it down and getting it closer to breaking down for good. Not changing your air filter can lead to mass destruction in regards to your central heating and air conditioning system unit. I have seen it happen to friends of mine time and time again from not changing the air filter when they should. A few people I know let the air filter sit for almost a year without changing it! Not only is that bad for the air quality, but it nearly destroyed their central heating and air conditioning system beyond any basic HVAC repair. So take 30 seconds of your life once every few months and change that air filter! It will save you thousands like I said before!
