Finally, friendly professionalism!
Great Works Heating and Air company came out to my home when my AC unit was blowing warm air. After my DIY Youtube search to see if the problem could be a simple fix, I proceeded and the basics. I cleaned the vents (which I never performed on the unit) to wash away all the dirt build up in the vents - but to no avail. Went back to Youtube and the fix was a little bit above my paygrade, but I had enough information to keep a AC professional 'honest' by pointng out some likely possibilities. Fortunately I guessed correctly and the courtesy and friendliness that was shown to my wife was graciously appreciated. My wife felt comfortable with the service technician in my absence, the price for part and labor was below my expectation and we will definitely use Great Works again as our Go-to HVAC specialist for our home.
