Looking for ways to beat the heat? July has been a scorcher in Burlington, and neighboring Massachusetts areas it looks like August will bring more of the same.
Try these tips to keep your air conditioning system running efficiently:
- Replace filters regularly! This is one of the easiest things to do yet one of the most commonly overlooked. Filters should be replaced monthly, so make it a habit by keeping a supply of filters on hand.
- Set your thermostat and leave it. Pick a temperature that you are comfortable with (perhaps 75°) and keep it at a constant setting. Turning the thermostat down doesn’t affect the temperature of the air blowing out of your vents. It makes the system run longer, not colder.
- Keep curtains, drapes and blinds closed, especially on the west-facing side of your house.
- Shade your air conditioner. Your unit works harder if it is in an area that receives full sun.
- Don’t block the AC unit. Keep air flow free from obstructions.
- Keep household appliances that produce heat far away from your thermostat. You don’t want an adjacent TV or water heater to contribute to a false thermostat temperature.
- Caulk around window frames to seal any leaks and check weather stripping.
- Invest in a few good ceiling fans or some smaller portable fans. Fans provide evaporative cooling as you sweat. If you buy a ceiling fan with lights, opt for those with Compact Fluorescent Lamps (pin-type) CFL’s, which last up to 15 times as long as incandescent bulbs.
- If your home has a fireplace, don’t send cool air up the chimney – close the damper and shut glass doors.
- Schedule regular service on your air conditioning system. Your system’s refrigerant charge needs to be checked annually, and the AC unit needs to be cleaned professionally. A/C Maintenance ensures your system is running at peak efficiency.
If you are concerned about obtaining optimal efficiency from your Air Conditioning system, be sure to schedule an A/C system maintenance check with your HVAC contractor. A professional will check multiple factors to ensure all air conditioning system components are operating properly, and that the system is meeting the manufacturer’s expectations for efficiency.
