Setting your thermostat properly is one of the most important things your can do with your HVAC system. In the wintertime, set the thermostat to the lowest setting at which you are comfortable. Do the opposite for the summertime and set the thermostat highest setting for your comfort level. Basic guideline settings are approximately 70 degrees in the winter and 78 degrees for summer. Remember, for both heating and cooling, your operating costs increase percentage-wise from for each degree your thermostat is raised or lowered.
Make sure your thermostat is away from heat generators like TVs, lamps, computer and stereo equipment.
Keeping your air filters clean is another easy way to ensure your that your heating and cooling system will function efficiently. Be sure to know where your filters are located and what type of filter to use.
Make sure that all windows and doors are shut properly. Your HVAC system will operate more efficiently as the heating and cooling loads will be decreased.
Proper addition of insulation to the attic and outside walls can help ensure maximum retention of heated or cooled air. You can also prevent unwanted air leaks by using storm doors and sealing cracks.
Be sure that none of your drapes or furniture are obstructing your vents or grilles. This also helps your HVAC system operate more efficiently as the heating and cooling loads will be decreased.
Having your indoor fan set to ‘Auto’ provides better humidity control in the summer and as a bonus, it costs less.
In the wintertime, sunlight can help ease the load on your HVAC system while the opposite holds true for the summertime. In the winter, open drapes, awnings, and window shades to increase sunlight and lower the heating load. In the summer, use your drapes, awnings, and window shades to block direct sunlight which will help reduce the cooling load.
The main outside unit (also known as the condenser coil) should be kept clear of any obstructions to ensure proper, efficient operation. Your system efficiency will decrease if the outdoor unit becomes restricted by things like grass clippings, leaves, dirt, lint, paper, and other debris. By making use of your garden hose, you can help keep the unit clean and clear.
All air ducts should be well-insulated and sealed with a vapor barrier.
Make sure that your clothes dryer is properly vented, including having it away from your condenser coil.
