About AC Maintenance

Regular AC maintenance is the key to reliable cooling, lower energy bills, and a longer-lasting system. Our preventive maintenance services include comprehensive inspections, cleaning, and tune-ups that keep your air conditioner running at peak performance throughout the cooling season. A typical maintenance visit includes checking refrigerant levels, cleaning condenser and evaporator coils, inspecting electrical connections, lubricating moving parts, checking thermostat operation, inspecting ductwork, testing safety controls, and measuring airflow and temperature differential. We recommend scheduling AC maintenance in the spring before the cooling season begins.

AC Maintenance FAQs

What HVAC maintenance can I do myself?

Homeowners can: 1) Change air filters every 1-3 months. 2) Keep outdoor units clear of debris, leaves, and vegetation (2-foot clearance). 3) Clean visible dust from vents and registers. 4) Check and reset programmable thermostat schedules seasonally. 5) Ensure furniture doesn't block vents. 6) Listen for unusual noises. Leave electrical, refrigerant, and gas work to licensed professionals.

What temperature should I set my thermostat?

For optimal comfort and efficiency: Set heating to 68-70°F when home and awake, and 65-68°F when sleeping or away. Set cooling to 78°F when home and 85°F when away. Each degree adjustment can save 1-3% on energy bills. Use programmable or smart thermostats to automate these settings.
