Seasonal Tips for Hot Months

Set It, then Forget It
Set your thermostat at 78 degrees or above for highest efficiency. Whatever temperature setting you choose, be sure to leave your thermostat at that setting.

When possible, delay use of heat-generating appliances such as dryers, dishwashers, vacuums, and other major appliances until evening on hot days.

Evening Breezes Only
Keep windows closed during the day. Sounds simple, but many people forget to close their windows in the morning, letting hot air into the house during the day. If you keep windows open at all, be sure you have proper security to deter theft. An open window is an open invitation.

Cool the Cooler
Provide shade for your window or outside central AC unit. You can increase the efficiency of your unit by as much as 10%, but follow the manufacturer's guidelines to prevent blocking airflow.

Give Your Windows Sunglasses
Installing effective shading and/or tinting to your windows can create big savings. White window shades or blinds can effectively reduce solar heat gain by as much as 50%.

Change Your Filter, and Call COLT for Check-ups
Changing your AC unit's air filter each month will increase efficiency and can prevent equipment failure. Based on our experience, we highly recommend permanent electrostatic filters. Not only are they more efficient (which will save you money), they are designed to be washed monthly and reused (which will save you money). Call COLT to get your permanent filter today! Be sure to call COLT at 602-712-1244 for a preventative maintenance checkup prior to the warmest months, then again before heating season.

Your Secret Weapon
Use ceiling fans to circulate air when using higher thermostat settings for a cool, comfortable environment and some cool cost savings as well. Ceiling fans generally cost less than $30 at home improvement stores and are generally far more efficient than using the air conditioner. Ask your COLT representative about optimum ceiling fan placement.

Optimize Your Air Ducts and Vents
Consider closing vents in seldom used or unused rooms, and leave the doors to these rooms closed. COLT can test for leaks and properly seal and insulate air ducts, especially running through crawlspaces and attics.
