HVAC Maintenance in Central New Jersey

Preventive maintenance for HVAC systems is a planned, routine service that inspects, cleans, tests, and adjusts heating and cooling equipment to keep it safe, efficient, and reliable. Most problems start with dirt buildup and normal wear that raise energy use and stress parts until they fail. A proper visit covers the whole system, not just a quick filter change, and lets a tech spot small issues—like a weak capacitor or improper combustion—before they become a no-heat or no-cool call. We service homes throughout the Somerset area with maintenance tuned to local seasonal swings. For AC, a $77 Air Conditioning Tune Up includes a 100% Satisfaction Guarantee and a no-breakdown guarantee all summer or your money back.

What a professional maintenance visit can include:

• Coil and heat-exchanger cleaning with airflow verification
• Testing for gas leaks and carbon monoxide; combustion and venting checks
• Refrigerant pressure checks and electrical tightening, including capacitor testing
• Duct inspection and cleaning options to reduce debris and improve distribution

Schedule service before peak season to prevent surprise breakdowns.

A typical HVAC tune-up from Guaranteed Service includes inspection, cleaning, testing, and adjustments for both AC and heating systems.

For heating, we inspect the heat exchanger with an infrared camera, clean burners and the exchanger, test ignition and safety controls, verify venting, adjust gas pressure, and check for gas leaks.
