I have come to realize that there are several reasons why the home is not efficiently or sufficiently heated or cooled.
Your HVAC equipment could be suffering from some issues.
Hopefully you have had your maintenance done on an annual basis, and you can tick that off your list. Check to make sure you have had the air ducts cleaned, along with the maintenance. Then you need to make sure the air filters are clean and free of debris. You may even want to check the thermostat to make sure it is working properly. There is one other thing that the homeowner can do to check for lack of heating and cooling. You need to look at the weatherstripping on your windows and doors. The weatherstripping is the first offense against loss of heat and air conditioning from your home. If the weatherstripping is worn, then you may need to replace it. The weatherstripping keeps the cold breezes and the summer heat from getting into the house. The weatherstripping keeps your heating and air conditioning from getting to the outside. Weatherstripping is found in all home centers and it comes with all of the tools you need along with a set of easy to follow instructions on how to install the weatherstripping. Once the doors and windows are properly sealed, you will probably find that you retain the heat and air conditioning much better and that your home is now easier to heat and cool. If your home doesn’t have weatherstripping, you really should install some and if you haven’t checked your weatherstripping in a couple years, you may want to have it replaced.
