I recently purchased a home and only a few days in, my AC went out. I had to go through my home warranty, and the first company I was set up with for my emergency claim would not return a single call. My home warranty company then gave me Fred's Heating and Cooling's number and not only did Fred answer on the first call, he was there the same day.
My boyfriend, who has a HVAC background (but couldn't touch the unit for warranty purposes) agreed that Fred was fair, honest and quickly diagnosed and fixed the problem. He told us other "add ons" that were optional and would make the unit more efficient but were not necessary.
After being fed up with other companies, it was refreshing to meet Fred and will be calling him for future HVAC needs.
