In Arizona, where temperatures reach the 90s and 100s for more than half of the year, it is essential to understand energy efficiency and to see to it that home cooling and heating system are operating at peak efficiency, the company said.

Chas Roberts’ energy audit can help homeowners determine where their home could be losing cold/hot air by measuring temperature differences in strategic places of a home, such as outside access doors, windows, and at the attic entrance, the company added. If the temperature is higher at these points than in the rest of the house, it’s likely that the house is losing air through these access points.

Chas Roberts also evaluates the efficiency of the current air conditioning and heating system by assessing the Seasonal Energy Efficiency Ratio (SEER), age and working condition.
