Most Midwestern states like Minnesota are known for their harsh winters. As a result, locals prepare for the winter season ahead of time and make repairs on their heating equipment. Unfortunately, all the efforts put into readying their heating systems are no match for excessive use or unpredictable weather.
Gas furnaces that are more than 15 years old, for instance, are prone to a failing heat exchanger or control module. As such, experts say homeowners are better off having the equipment replaced than having it repaired.
For fairly new gas furnaces, expert troubleshooting techniques may do the trick. Homeowners just need to know when they can resolve the issues themselves or when they need to call on experienced Maple Grove, MN furnace repair specialists like those from Marsh Heating & Air Conditioning Co., Inc. Here’s a short guide to help them out:
Filter with dust/dirt build-up
Every furnace is equipped with a filter to keep dust and dirt at bay. Over time, these dust and dirt will build up especially when homeowners open doors and windows frequently and have more than one furry pet. Dust and dirt buildup means it’s time for a filter change, which is an easy task to manage as long as homeowners have their manual handy.
Igniter doesn’t light up
The igniter lights up the flame sensor to burn the fuel and produce the needed heat. When an igniter fails, the flame sensor turns off the furnace, cutting off the gas supply as a result. As this problem may require turning gas valves off and on, it’s best to let Maple Grove, MN heating & air conditioning contractors handle this one to ensure safety.
Noisy furnace
A furnace that makes loud and bothersome noises may indicate a problem with the blower motor. This component draws the air in, warming it and distributing it into various home areas through the main duct. Replacing a furnace blower requires several steps, and it’s best to leave the job to dependable HVAC contractors to ensure the procedure is done properly.
Failing thermostat
If the furnace has a defective thermostat, it will fail to operate efficiently, producing indoor air that’s too warm or too cold. Replacing the thermostat is a fairly easy task if homeowners are familiar with its type. Still, as the job requires manipulation of some wires, it is one of the tasks best left to the professionals for safety reasons.
A failing gas furnace is a no-no in this harsh winter. As such, homeowners must be ready to either put their handyperson skills to work or depend on HVAC professionals.
