When your furnace goes out during a cold Minnesota winter, you need a reliable repair service to come out quickly and diagnose the problem so that your safety and comfort can be restored. The most common reason why Minnetonka and Eden Prairie homeowners call for wintertime furnace repairs is a lack of heat coming from the HVAC unit. With help from an experienced service for furnace repair in Eden Prairie MN, your home’s heating system will be restored to its full functionality.
Thermostat
The most likely reason why your gas furnace is not heating your home is due to the thermostat. Before calling for a furnace repair in Minnetonka MN, check the thermostat’s settings. A power outage could have reset the thermostat so that it is no longer in the heating setting. If the temperature inside of your house is higher than what the thermostat is set at, the thermostat will not trigger the furnace to cycle. Your thermostat could also have developed an electrical or mechanical problem, which should be fixed by your HVAC technician.
Pilot Light
A problem with your furnace’s pilot light is another common cause of a lack of heat. Gas furnaces with a non-electric ignition require that the pilot light be on at all times. The pilot light’s sensor could also be malfunctioning. A buildup of dust or dirt could have broken the beam of the sensor, causing it to turn off the pilot. Issues with the pilot light are best left to an experienced heating repair technician.
Dirty Air Filter
Every 2 to 3 months, your furnace’s air filter should be replaced. With each cycle of the furnace, some dust and other debris gets trapped by the filter. Once the filter’s pores are filled, the heated air produced by the HVAC unit will have a hard time passing through it. If the air cannot pass through the filter, then it will not get into your home’s air ducts and into your living spaces. You can slide the filter out of its housing and check if it is dirty. The HVAC technician can replace the filter for you.
