Periodically you just know it when something is wrong with an appliance in your home… This was the case when I kept hearing this high pitched squeak every single time our central heating and A/C appliance would come on! This was going on for numerous weeks and I didn’t actually know what was going on… But what I did know was that our lake dwelling was not heating or cooling the way it should have been! At this point I contacted the heating and A/C professionals to see if they could figure out what the noise was and why our central heat and air conditioner appliance was not performing to its full power. I honestly felt like a real dope head when the heating and A/C appliance specialist looked at myself and others with this crazy stare and told myself and others that a few of the HVAC vents in our lake dwelling were half closed! I didn’t even realize this. But had I been a little more on top of things I undoubtedly would have caught this. So it was just my luck that I blew a few hundred dollars just to have the heating and A/C professional open up our HVAC vents, laugh at myself and others and tell myself and others that it basically was something any little child could have repaired! This will teach me in the future to pay careful attention to things and troubleshoot more when something isn’t right instead of dashing to the iphone to call a professional and waste a huge amount of money. Especially when it comes to our central heating and A/C appliance.
