What Should You Expect On A Central AC Maintenance Checkup?

Hi My Name is Tom Henry with Wilbur Henry Plumbing, Heating and Cooling in York PA. Our website is www.wilburhenry.com/ and our phone number is 717-755-5461.
My son Dave Henry discusses what to expect from a service call.
Some of the things we check are the refrigerant levels.
That the ac unit is level.
That the filter is clean.
We also clean the unit and in this video we also demonstrate how we clean a central ac unit. We spray on liquid that foams up over about a 5-10 minute period.
The foam expanding pushes the debris out. We then hose off the dirt. Best thing is we speed up the cleaning process to 60-75 seconds.
