I recently found out the hard way that insulation in your house’s walls is way more pressing than you might ever have thought that it was. I never legitimately realized that it was that much of an concerns until I started having concerns with what I thought was my HVAC unit in my house. At first I thought that my temperature control was messed up and that it was causing my heating, ventilation, and A/C to malfunction somehow. But when I checked it, the digital programmable temperature control was working just fine. At least, it was working great as far as I could tell. I’m not an HVAC serviceman, by any means. But for some reason, our heating just wasn’t heating our house, no matter how far I turned up the temperature on the temperature control control. My feet were still frigid and my hands were still cold, no matter how many layers of sweaters and blankets I put on. I started wishing that both of us had installed radiant heated flooring in the lake house when both of us put in our modern heating, ventilation, and A/C plan last year. I guess that if both of us had radiant heated flooring then both of us would never have cold feet again! Well, I finally gave up and called our local heating and cooling experts and they came out to assess the situation. The HVAC serviceman said that it wouldn’t matter how relaxing of an HVAC unit both of us had or even if both of us had radiant heated flooring – our insulation was too old and of such terrible quality that our heating wouldn’t stay in the lake house anyway!
