Weather has a direct relationship with your energy bill, especially if you live in an inefficient home. Humans have limited tolerances for temperature ranges and it’s not healthy to be too cold or hot. Fortunately, HVAC systems keep homes at comfortable temperatures, but they do so by consuming nearly half the energy you use at home in a year.
Aspects of Weather
The outdoor temperatures drive the need for heating and cooling and in our region, humidity makes a difference. In the summer, high humidity prevents the evaporation of skin moisture, which is how people cool themselves. As the humidity creeps into a home, it gets more uncomfortable.
Air conditioners remove humidity as a byproduct of cooling and as the system runs, the humidity falls, increasing your comfort. The kitchen and bathroom fans also remove excess humidity using far less energy than a cooling system.
Managing Weather Indoors
Nobody can control the weather, but there’s plenty you can do to keep it from affecting your indoor comfort. The amount of insulation you have, the tightness of your home’s envelope and the quality of the windows collectively make a difference in your energy bill. These materials slow the rate that heat enters or leaves your home.
- Insulation in the attic is especially important, since the roof has 24/7 exposure to the weather. The U.S. Department of Energy recommends 10 inches in the attic to prevent heat transfer year-round.
- Air leaks in the envelope introduce hot and humid air into your home all summer, which also increases the cooling load. It’s easy and inexpensive to seal most leaks with caulk. Fresh weatherstripping around exterior doors will cut drafts.
- Single-pane windows or dual pane windows that have lost their seal offer little resistance against heat transfer year-round. Solutions include window replacements, shade screens on sunny windows, or thermal window coverings.
Home improvements that lower your energy bill as a result of the weather will keep your home more comfortable and reduce the load on your HVAC system. For more information, contact Beyer Boys, providing HVAC services for San Antonio homeowners.
