When our heating and A/C professional came out to the home to check out my HVAC that had been having problems, I was talking about how I cleaned the HVAC unit pretty good! When he checked the unit, it was pretty shiny from the outside, but when he opened it up, it was a mess. There was so much dirt and debris built up, I couldn’t believe it, and I was confused because I thought the air filters I was using were pretty good. When the guy looked at the air filters though, he said under his breath, “fiberglass air filter?” He clearly disapproved of the air filter, even though he didn’t make a big deal of it, he suggested that I leave all of the heating as well as A/C repair up to the professionals. He said it was alright to do what I did with wiping down the HVAC unit real well, but I should constantly shut off the power to the unit before making any moves like that, as a safety issue. I understood what he was saying, and I did not want to risk getting killed from electrocution or getting hurt badly. When we went to the outdoor air conditioning condenser, he shook his head. He said again under his breath, “No wonder this idea is struggling.” He pointed out that there were tons of leaves as well as shrubbery debris built up around the condenser basically choking the idea from essential air intake as well as the fin coils being clogged could not do their task. He opened up the unit after managing the shut off and he sprayed the debris out from within. He cleaned the fan blades real well and carefully as well as the condenser looked good when he was done. When he was finished, the air conditioning was easily working perfectly!
