I often take walks during my supper hour, & I have more than 2 neighborhoods that I alternate for my walking routes, no two nights are ever the same considering changes in the weather, wildlife, bikers, cars & service women. The other day the weather was especially agreeable, not too sizzling or cold, not too windy or humid. So I decided to walk a bit further than normal & explore a weird neighborhood. I was impressed with the sizable homes with charmingly manicured grasss & sprawling shade trees. I happened to pass an especially high hedge row along the sidewalk when I could hear someone on the other side, but once I walked past the bushes, I could see that it was an Heating as well as Air Conditioning repairman performing a Springtime service service. My friend and I chatted for a few minutes, & the conversation naturally led to the service that she was performing on the homeowner’s cooling system! She had removed the fan cage from the the exterior condenser/compressor to scrub it out. I couldn’t know how much debris she had taken out! There was even more junk lying nearby on the ground that she had cleaned off of the fins. She told me that you should never use a power washer to scrub the fins, which she said can certainly harm them. Next she was planning on pulling out the leaves & weeds from around the outer unit. I asked him how much training was required to be an Heating as well as Air Conditioning worker, & she explained that our local community school gave a five-month training course. After my pal and I exchanged our ‘Have a wonderful day’s’ , I realized how much I had learned about the heating & cooling industry in the short time that my pal and I had visited.
