I recently found out that you should have your Heating and A/C system cleaned and diagnosed twice a year. I do not know I have ever had our Heating and A/C system diagnosed but, I am handy with small beach house repairs so I decided to just repair our Heating and A/C system myself. I watched a lot of videos online and learn up a bit and then I got to work with our tools, however everything seemed to be going great and, various hours later, I put everything back together after oiling, and cleaning, and vacuuming the whole system out. However, Heating and A/C system would not turn back on. I took everything back apart and checked all of the connections however still our Heating and A/C wouldn’t work, however finally, I called out the Heating and A/C professionals! A real Heating and A/C professional came out the absolutely next day and the serviceman looked at our Heating and A/C system, flipped a little switch on the side, and everything started toiling. I felt so dumb. I do not remember turning our Heating and A/C system off. I didn’t even know you could turn an Heating and A/C system off appreciate that; with an on-off switch. I suppose the switch got bumped when I was moving things around. The Heating and A/C serviceman did say I did a pretty wonderful task cleaning and he gave me a few hints and tricks for our next attempt. I am not sure there’s going to be a next attempt though. Next time I know I’ll just call out the Heating and A/C professionals and have them do it right to begin with. Then I will know that I didn’t chop anything in our Heating and A/C system.
