In winter hundreds of people call furnace repair experts because of a problem with their heating system.

When you know what the most common furnace problems are, you can take proactive measures to prevent them.
- A bad maintenance: You forget about an annual furnace maintenance and inspections that could prevent unexpected problems and breakdowns. Such routine inspections can help the appliance run more effectively and reliably.
- Dirty filters: Dirty or clogged air filters lower airflow, making a furnace work harder to circulate. In some circumstances, a clogged filter may damage the limit switch, which controls the fan.
- Wear and tear: Normal wear and tear can bring about airflow problems, heat control-related problems or even overheating.
- Electric ignition or pilot control problems: At home or commercial space a faulty ignition or pilot could make the heating work with difficulties. Thermocouple problems, drafts or clogs in the appliance may result in an unlit pilot light.
- Malfunctioning thermostat: A faulty thermostat can lead to problems with the fan or comfort levels.
- It doesn’t heat at all: A furnace that doesn’t work may have problems with the thermostat setting, power, gas or the pilot light.
- It doesn’t heat enough: Thereunto a clogged filter, a furnace may not produce enough heat if it’s size doesn’t suit for the space.
- Constant cycling: Cycling between the “On” and “Off” modes may indicate a clogged filter, improper airflow or a bad thermostat setting.
- The blower unceasingly runs: Blower issues may indicate a problem with the limit switch, which a professional may need to replace.
- A noisy furnace: Rumbling, squeaking and rattles are awful. But what is more important, such problems can also be a bad signal for you - the sounds may indicate a mechanical problem, airflow reductions or a clogged burner.
Tips and Advice for Repairs
- Change the air filters: Dirty air filters lead to a plurality of furnace problems. Clean or replace the filter regularly (1 or 2 times a month) , in concordance with the manufacturer’s directions. A furnace repair professional can show you how to do this.
- Check the thermostat: In case it seems as if your furnace doesn’t produce any heat, just check the battery level in the thermostat. There are some models, in which simply replacing the battery may do the trick.
If the blower fan doesn’t switch off or the furnace cycles constantly, check the thermostat settings. The fan setting should be on “Auto.” In the “On,” “Low,” “Medium” or “High” modes, the fan will run without intermission.
If the furnace doesn’t seem to produce enough heat, check the thermostat’s setting to make sure it’s on “Heat” mode. Then check the temperature to make sure it’s set to one that’s higher than the current room temperature.
But, what if nothing seems to work? Try to purchase a new. Make certain that the new thermostat matches your furnace in regards to capability and capacity, or you may run upon future problems.
- Check the circuit breaker and power supply: If the furnace stops working or the thermostat’s screen is blank, check if the circuit breaker tripped or blew a fuse. Also, make sure the power cord is plugged into an outlet.
