Behind my house sits my central heating and air conditioning system unit. When I bought my central heating and air conditioning system unit, I had 2 choices. I could have had the central heating and air conditioning unit put on the side of my house or behind my house. Either way it would be able to be hooked up to my ductwork and all. I chose behind my house because it is behind a locked gate and no one would be able to mess with my central heating and air conditioning system unit. My central heating and air conditioning system I used to have before this one used to get messed up all the time by either teenage vandals or kids next door playing ball and always denting my central heating and air conditioning system unit. I take pride in making sure my central heating and air conditioning system unit is always as good as new in every single way. Not just keeping up with the central heating and air conditioning system by having regular HVAC tune ups and check ups. But also making sure the unit itself is not dented and always stays in the best shape. This actually plays a major part in how long your central heating and air conditioning system lasts. If you have a banged up central HVAC unit, it could end up to where it causes a lot of breakdowns when it comes to the motor. At least that’s what I heard. Never the less, I take care of my central heating and a/c unit as if it were my car! That’s the only way to do it.
