Tips for Cooling
Ensure energy efficiency and prolong the life of your air conditioner by following these simple tips:
- Quad Cities AC service customers: Keep your air conditioner clean and free of obstructions.
- Replace the air conditioner filter every month.
- When temperatures drop, continue to use air conditioning to remove humidity — this reduces the burden on your air conditioner, saving energy.

Energy from the Earth
For centuries, people have drawn on the earth as a source of comfort. For example, some Native Americans and American settlers carved homes out of hillsides to keep warm in winter and cool in summer. The ground insulated them from extreme heat and cold.
Today, ground source heat pumps, also known as geothermal heat pumps, work on a similar principle. These units utilize the earth's steady ground temperatures to exchange heat between a home and the earth.
Heat pumps operate like a refrigerator, with a system of liquid-filled pipes set in the ground in place of the refrigerator coils. When cooling your home, the system sends the heat in your home into the earth through the pipes. When heating season comes, the system pulls heat from the earth for use in your home.
Geothermal heat pumps are very efficient and environmentally friendly, allowing your family to rely more on the earth and less on fuel.
