The hottest period of the year is here, and now is the time to make sure your HVAC can keep the house cool. As summer cranks up, the unit may have trouble delivering optimal temperatures, especially if it’s not maintained properly.

The HVAC system in a home or business can account for almost half of the overall energy bill. Even as a rough estimate, 50% is a considerable sum in terms of annual expenses.

We compare modern HVAC and AC units using efficiency ratio systems - just like cars. A Seasonal Energy Efficiency Ratio (SEER) is the most commonly used standard for rating AC units.
