Dirty Coils in a home inspection

There are some basic things you can do to improve your A/C performance. Extend the life of the A/C. Reduce your utility bills, and help when you have a home inspection. As a home inspector in OKC, here is an item.
Change the A/C filters on a regular basis. I have been at a home inspection when a HVAC Contractor was present. The A/C was only getting one to two degrees cooler. The contractor pulled the filter and it dropped three degrees in just a couple minutes. The A/C still did not work properly but the filter made a huge difference.
