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

How do I relight my furnace pilot light?

For most furnaces: 1) Turn the gas valve to "Off" and wait 5 minutes. 2) Turn it to "Pilot." 3) Press and hold the reset button while bringing a lit match or lighter to the pilot opening. 4) Once lit, continue holding for 30-60 seconds. 5) Release and turn the valve to "On." If it won't stay lit, the thermocouple may need replacement—call a professional.

How often should I have my HVAC system serviced?

You should have your HVAC system professionally serviced twice a year: once in the spring for your air conditioning and once in the fall for your heating system. Regular maintenance helps prevent breakdowns, extends equipment life, improves efficiency, and maintains manufacturer warranties.
