Keep your cool with simple A/C maintenance
- Clear leaves, brush and dirt from inside your air conditioner’s top grille.
- Remove your cover/board if applicable
- Trim nearby shrubs and bushes to allow at least two feet of clearance around the unit.
- Set the thermostat to cooling mode and run your air conditioner a few minutes to make sure it’s working.
- Schedule an annual checkup of your air conditioning system.
- Replace your air conditioner filter once a month. Dirty filters restrict air flow and can waste energy.
- If you use a room air conditioner, install it on a north-facing wall to keep it out of the sun.
- If it’s time to replace your air conditioner, look for an ENERGY STAR® qualified model to help reduce cooling costs up to 20 percent.
Don’t let April showers bring May mildew
- Clear leaves, pine needles and other debris from gutters and downspouts to ensure proper drainage. Check that they’re stable to avoid flying debris during storms.
- Be sure downspouts slope away from your house. They should carry water at least 5′ from foundation walls.
- Position lawn sprinklers so they don’t spray your home’s walls.
- Examine window and door seals and weather-stripping. Reseal if needed.
- Move furniture a few inches away from the inside of exterior walls to increase air circulation.
- Check windows for condensation and walls for water stains, which are signs of too much humidity.
- Keep your home’s relative humidity between 30 – 50%. A humidity control system such as Humiditrol® can safely control humidity.
Take control of home energy costs
- Reduce air leaks in your home by caulking, sealing and weather-stripping around doors and windows.
- Use exhaust fans to reduce moisture in the kitchen or bath, but turn them off when they’re no longer needed.
- Make sure your refrigerator’s seals are airtight. Test by closing the door over a dollar bill. If you can pull the dollar out easily, the seal may need to be adjusted.
- Wash only full loads in your dishwasher and clothes washer.
- Turn off lights you don’t need to save energy and reduce extra heat in your home.
- If it’s time to replace your air conditioner, choose an energy-efficient model with multi stage cooling, such as the XC25 from Lennox. Two levels of operation allow you to rely on the low setting most of the time.
- Prepare dinner on your outdoor grill to help reduce your air conditioner’s load.
- Check ducts for air leaks, including holes or separated sections.
