On hot, humid summer days in Nashville, when the mercury climbs above the 100-degree mark, you probably turn up the air conditioning in your home to beat the heat. And on those winter evenings when the temperature drops below freezing, you switch on your heat to stay cozy and warm. As you know, using your HVAC system significantly increases your monthly utility bills. To stay comfortable on hot and cold days while keeping your bills down, follow these Nashville HVAC tips.
Seal Your Doors and Windows
Since heat tends to flow from warmer areas to cooler ones, hot air will escape through any little cracks and spaces during winter, and flow into your cool, air conditioned home in summer if it can. For every bit of heated or cooled air that escapes, your Nashville HVAC system will stay on longer and consume more energy. Small gaps between doors and windows and their frames allow air to flow between your home and the outdoors, but you can prevent this by installing weather-stripping and using door snakes to block drafts.
Use a Programmable Thermostat
If your home stands empty for eight hours a day while everyone is out at work or school, you don’t need to have your HVAC running during that time. On the other hand, it’s unpleasant to find a home too hot or cold when you come home. A programmable thermostat will automatically maintain a certain temperature in your home while you are away, then switch the HVAC on and off automatically as needed, so you always come home to a comfortable house but never pay for climate control while you’re away.
Change Your Filter
In order for the blowers to work properly, your heating and cooling system has a filter to catch any debris that might clog the fans or damage the belts. Depending on the type of filter you use, it will reach the end of its life within four to six weeks when it becomes saturated with dirt and dust. Neglect to change the filter, and the air pressure in your ducts will suffer, then your HVAC system will have to run longer to reach the temperature specified on the thermostat. If you don’t like the idea of throwing away a filter each month, invest in a washable model that will last several years.
