Fletcher Heating & Air-Hvac: Emergency HVAC Repair Serving International Falls, MN 56649

In our extreme cold, short cycling is often caused by a clogged air filter restricting airflow, a malfunctioning flame sensor, or an oversized furnace that heats the space too quickly. This constant on-and-off operation strains your system. We can diagnose the specific cause—often related to the harsh conditions—and perform the necessary repair to restore normal, efficient cycles.

Furnace ignition failure in sub-zero temperatures is a common emergency call for us. It's frequently due to a faulty ignitor, a tripped limit switch from overheating, or a draft issue preventing the pressure switch from closing. For safety and to prevent further damage, it's best to call us for a professional diagnosis and repair. We're experienced with these cold-weather-specific failures and will get your heat restored promptly.

Before winter hits, a professional tune-up is crucial. We check critical components like the ignitor, flame sensor, heat exchanger, and thermostat calibration—all of which are stressed by our cold climate. This proactive service can prevent most common ignition and short-cycling problems, improve efficiency, and extend the life of your system, giving you peace of mind through the long winter.
