Two core services keep your Central air conditioning running — a repair when it fails, and a replacement when it's time to upgrade.
Your air conditioning has stopped cooling or isn't running at all. We diagnose compressor failures, refrigerant leaks, electrical problems, and blower issues. Fast, honest repair.
Upgrade to a new high-efficiency Armstrong Air system. We handle removal of old equipment, installation of new units sized for your home, and system testing so you know it's running right.
A spring tune-up catches refrigerant leaks, worn capacitors, and dirty coils before they fail — it's cheaper to prevent a breakdown than to fix one in 95-degree heat. Our maintenance plan covers annual tune-ups that catch problems early and keep repair costs down.
A new HVAC system is a real investment, and Harmon Heating & Cooling works with Service Finance to help make that investment manageable. Whether you're replacing an aging furnace before winter or upgrading to a more efficient central AC system, financing options are available so an unexpected repair or planned upgrade doesn't have to wait.
Our team can walk you through financing options through Service Finance at the time of your estimate, so you know what to expect before any work begins.
