After nearly 40 years of serving Valley families, the techs at Donley Service Center have pretty much seen it all. They’ve provided relief during Phoenix’s all-time record high of 122 and warmed plenty of homes not used to below freezing temperatures.

While July is usually our hottest month, now is the time to prepare your air conditioner and home to ensure the lowest energy bills and maximum efficiency. Donley experts are available to discuss the following tips:

Change your air filter

• Our dry, dusty climate can quickly clog your filter, which can lead to higher energy bills and more repairs. It’s a good idea to clean or replace your filter every month.

Clearing and cooling the area

• Planting shrubs or trees can provide shade to the a/c unit, which leads to less electricity being used. But, not too close or you’ll restrict airflow. Make sure the area is free of leaves, weeds and debris.

Seal the leaks

• The fastest way to save money is to use caulk or weather-stripping on your doors and windows.

Set it and forget it

• You won’t conserve energy by constantly changing the thermostat. Set it at the highest comfortable level and leave it. Or, try a programmable thermostat that will automatically adjust for times you are away and sleeping. Note: Keep your set back point 4 degrees or less when setting a programmable thermostat.

Use ceiling fans

• They move the air so you feel cooler, but turn them off when no one’s in the room.

Move the lamps

• Thermostats can pick up the heat from lamps, TV’s and appliances so keep them away.

Invest in sunscreen

• Keep blinds and drapes closed and install sunscreens to keep the heat out.

Although the Environmental Protection Agency saysthe average air conditioner lasts 15 to 20 years, in Arizona we generally experience a shorter life span – closer to 12-15 years. While it may seem like a pretty wide span, we know that properly maintained units that are checked annually by qualified technicians last the longest and run the most efficiently during our triple digits.
