D Marks Enterprises - Schenectady's Local HVAC Services

Yes, a furnace ignition failure in winter is a critical issue for both comfort and safety, as it can sometimes indicate a problem with the gas valve or heat exchanger. D Marks Enterprises prioritizes these emergency calls for Schenectady homeowners. Our technicians are trained to diagnose and safely repair common ignition issues, such as faulty ignitors or flame sensors, to restore your heat quickly and reliably.

Common signs include reduced cooling, ice forming on the refrigerant lines, a hissing sound from the unit, and higher-than-normal energy bills. For Schenectady homeowners, a refrigerant leak means your system is working harder and inefficiently. Our repair process involves using specialized tools to locate the leak, sealing it, and then carefully recharging the system to the manufacturer's exact specifications, restoring efficiency and cooling power.

Our Schenectady-focused maintenance service is proactive care for your system. Before winter, we thoroughly clean and test your furnace's ignition system and heat exchanger to prevent unexpected failures. Before summer, we check refrigerant levels, coil cleanliness, and electrical connections in your AC to catch small leaks or issues early. This preventative approach improves reliability, extends system life, and helps avoid costly emergency repairs during peak seasons.
