Derek Cole shows a filthy HVAC unit in the graveyard and explains how dirt buildup kills efficiency, makes the system work harder, and wrecks your indoor air. Regular cleaning and servicing keeps it running right.
I'm back here at the office in the unit graveyard. I call it that because this is where we put the old units after they've been replaced. I like to come out here and take a look at them and see what you are breathing inside your homes. So take a look at this unit. This is a package unit we just replaced. This is the old one. Look at that. Coral, dirt, stuff, build up on it. All this makes the unit work harder, become it becomes less efficient, becomes harder to transfer heat through these coils. And on top of that, you're breathing this stuff in the house. So, as usual, get your unit clean, serviced and checked. Help prevent this from happening to your system at home.
