I recently found out the hard way that insulation in your house’s walls is way more important than you might ever have thought that it was. I never certainly realized that it was that much of an troubles until I started having troubles with what I thought was my HVAC unit in my house. At first I thought that my thermostat was messed up and that it was causing my heating and a/c to malfunction somehow. But when I checked it, the digital programmable thermostat was certainly working just fine. At least, it was certainly working superb as far as I could tell. I’m not an HVAC dealer, 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 thermostat control. My feet were still freezing and my hands were still cold, no matter how many layers of sweaters and blankets I put on. I started wishing that every one of us had installed radiant heated flooring in the home when every one of us put in our new heating and a/c unit last year. I assume that if every one of us had radiant heated flooring after that I would never have freezing 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 company said that it wouldn’t matter how good of an HVAC unit every one of us had or even if every one of us had radiant heated flooring – our insulation was too outdated and of such poor quality that our heating wouldn’t stay in the home anyway!
