System age and condition
Cooling equipment loses efficiency as it ages. Age is the first thing your Home Efficiency Check captures.

HVAC & Air Conditioning
Your air conditioning is usually the largest single load in the house. Every Home Efficiency Check reviews its age, efficiency, and comfort before anything else is recommended.
