When you pay a contractor to perform a repair for you, then you have a right to complain about an awful experience. However, when you ask a favor from a friend then you have no right to complain about anything, no matter what happens. I actually tried to save a little money plus call in a favor from a friend, instead of using the professionals, plus I learned a serious lesson! I have known Sandra for a couple of years now! My buddy and I aren’t best friends but we hang out from time to time. When my cooling system stopped working, my first thought was to reach out plus ask Sandra to inspect it for me. I knew that Sandra was a certified Heating and A/C device tech, plus hoped she could supply me some expert advice… Sandra came over a single night, plus we had a few beers plus a joint before she inspected my Heating and A/C device. She updated some fuses, plus sealed a couple of hairline cracks in the HVAC duct. Overall, she said my system was in fine shape plus provided my heating plus cooling devices a wash bill of health, and two weeks later everything stopped working. There was no heating, no cooling, nothing! Even the fans in the system wouldn’t work! Suddenly Sandra isn’t taking my calls, plus I have no other choice but to bite the bullet plus contact a local Heating and A/C contractor. I obviously need a professional opinion, because Sandra doesn’t know squat about cooling devices. In the future I will not take secondhand advice about my heating plus cooling device, I will call a licensed pro.
