HVAC Repair Andover MA | Call Heating and Air

In Andover's winter climate, a common culprit for ignition failure is a dirty or faulty flame sensor, a worn-out igniter, or issues with the gas valve or electrical connections. Our technicians are trained to safely diagnose the exact problem. We carry common parts on our trucks and can often complete the repair in a single visit, restoring heat to your home quickly and reliably.

Uneven heating is a frequent issue in Andover homes, often due to an imbalanced duct system, blocked or undersized vents, or issues with your furnace's blower motor. We perform a thorough HVAC system evaluation, including checking airflow at each register. Solutions may involve ductwork adjustments, installing zoning dampers, or cleaning/replacing filters to ensure even, comfortable temperatures throughout your entire house.

We recommend bi-annual maintenance, ideally in the fall for your heating system and spring for your AC. For Andover homes, our fall tune-up focuses on critical heating components like the heat exchanger, ignition system, and blower to prevent winter breakdowns. This proactive service improves efficiency, extends system life, and helps catch small issues—like a weakening igniter—before they leave you without heat on a cold night.
