GFI Money Saving Service Tips

Spring Maintenance Tips
Air Conditioners

Remove cover from Air Conditioner as well as all accumulated debris

Make sure A/C circuit breaker is in the ON position (Save a service call)

Replace the furnace filter. Air conditioners won’t run efficiently with a dirty filter in place.

Mark your calendar to schedule your system clean and check for May (Or better yet, join our Planned Maintenance Club and we’ll call you!)

Humidifier

bryant humidifierReplace the water panel at the beginning of the season to avoid water overflow

When daytime temps remain consistently above 50 degrees, turn humidifier off.

Turn the water supply on

Be sure the humidifier is plugged into the designated outlet

Set humidistat to highest setting and turn fan switch on thermostat from AUTO to ON

If humidifier is operating properly water should be visible at the end of the drain tube.

If humidifier is operating properly, reset fan switch and set humidistat to appropriate setting

If unit fails to operate, turn humidistat off and call GFI for service 630 879-1544

Water Heater

Do you know that it’s important to drain a few gallons of water from your water heater periodically?

Spring is a great time to perform this routine maintenance to avoid sediment buildup in your tank that can shorten the life of your unit.

It’s easy to do or you can ask your GFI service technician to perform this money saving task while we’re in your home.
