I bought my home approximately three years ago. It is an older home, and there were a lot of necessary renovations to be done. That was a favorable selling feature for the house. I didn’t appreciate how much was definitely left to do, until I actually moved in. The first Winter in the home was very revealing. I hadn’t seen that several of the windows on the upper level were still original, and weren’t in as good of shape as I originally thought. I was facing an overly high gas bill because I was blasing the heating unit at max capacity a lot more than I normally would. The furnace just couldn’t handle demand and there were drafts in the house. It wasn’t an optimum situation. The actual Heating & Air Conditioning equipment was only a few years old, so I knew it wasn’t the source of the issue with that. I had an HVAC technician come out & complete some routine maintenance just to double check that all components were working at their best. The guy was knowledgeable and he put my mind at ease. He assured me that the Heating & Air Conditioning components were in good condition. I definitely need to update those older windows at some point in the near future. I am sure I could recoup some of the investment in the reduced energy bills. I am paying a fortune to heat and cool the house. Hopefully, in a few years, I’ll be able to afford some more improvements to the house. I am looking forward to making the home far more energy efficient so that I can trim the cost of my energy bills. It’ll be worth the time, effort and money.
