It had been nagging at myself and others for two winters. Our house was a well made lake house that I prepared each Winter for the cold. My preparations were to help keep the house cozy and improve the efficiency of the gas gas furnace. I made sure all the weather stripping was wonderful and the storm doors were tight. The insulation in the attic was more than enough. And I had the Heating, Ventilation and A/C specialist come out each fall to do the heating maintenance on the gas gas furnace. I wanted to be sure that I didn’t leave anything out so I even went online for other tips on reducing Heating, Ventilation and A/C heating costs. But I still found that the gas gas furnace ran far too much and the heating costs were significant. Plus, the house just never seemed legitimately warm. Well, I just couldn’t provide up. So I legitimately did some thinking when it came to where this Heating, Ventilation and A/C heating leak could be. I mean that’s the only thing that made any sense. I recognize the house was slender otherwise so, there had to be a culprit anywhere that was letting Heating, Ventilation and A/C treated air out and chilly air in. Prior to us buying the house, the previous owner updated all the windows with double paned windows. It dawned on myself and others that perhaps they weren’t officially insulated when they were installed. And I was right! I found numerous windows that were imofficially installed. Once I got those things insulated officially, the heating cost dropped care about crazy. Now, the people I was with and I are cozy during the worst the Winter can throw at us and the people I was with and I don’t have the gas gas furnace running all the time.
