Your mother was right about keeping clean. But, was she thinking about parts of your air conditioner and furnace?
If your AC/furnace is dirty on the inside, it can cost you big bucks. You can pay higher monthly utility bills AND need to replace your system sooner than necessary.
Here's a normal, clean evaporator coil (below). All of the air in your central HVAC system passes through this coil. This coil provides the cooling for your house in the summer. If you have a heat pump, this coil provides most of the heating for your house in the winter.
Compare the coil above with the coil below. Notice the debris (dust, mold, hair, who-knows-what) on the coil below. All of the air in the house passes through this coil. That's the air we breathe! Yuck! How long can you hold your breath?
So, what do we need to do? We need our coils cleaned.
Can anybody do this? No, it's the job for a licensed HVAC technician. Some techs will spray a surface cleaner on the coils and wipe it off. That's generally NOT good enough to clean all of the debris that's down in the middle part of the coil. Most times the coil needs to be removed so that it can be cleaned effectively.
Now you know. So, get your coils cleaned and start saving some money! Tell 'em Tom sent you!
