Here Are Some Furnaces Problems That Need Professional Repair Services

Posted on

A furnace is an integral part of the heating, ventilation, and air conditioning (HVAC) system in your home. It heats the air which is then circulated by the HVAC system keeping your home warm during cold seasons. Furnaces can be categorized as gas, electrical, propane, or oil-based depending on their powering system. Like any other home equipment, furnaces experience problems that affect their functionality, requiring repair. However, their fueling systems make repair risky as mistakes could lead to complete damage to your HVAC system, gas explosions, or fire outbreaks. Hence, you should let a professional handle the repair job. The following are examples of problems with your furnace that need professional repair services

Faulty Thermostat

The thermostat regulates how the furnace operates by measuring temperature levels in your home. It records the temperature conditions and transmits the readings to the heating system, which relies on the information to either increase or reduce the supply of warm air. It's like the furnace's brain. Thus, issues with the thermostat reading directly result in problems with your furnace. For example, if your thermostat wrongly records high temperatures during cold conditions, the furnace won't produce enough heat to warm the house. On the other hand, abnormally low temperature readings during hot seasons result in overworking the furnace and increased energy bills.

Clogged or Filled Filters

Filters are a crucial part of your heating system as they keep air and your ductwork clean. They help block pollutants, dirt, dust, and other allergens from entering your home, ensuring you get clean air from the furnace. Filters get clogged over time and need regular replacement to ensure your furnace continues to operate at optimum levels. One way to know that you need filter replacement is when the furnace is producing loud, high-pitched squeals. That means that the furnace is struggling to pass air through the clogged filters. Let a professional replace filters to avoid physical accidents from falls and prevent exposure to dirt and harmful allergens that may result in health complications. 

Ignition Failure

An ignitor is an essential component in a furnace as it creates the spark that initiates heating. When the ignitor fails, the furnace becomes incapable of heating air and circulates air as received from outside, regardless of the temperature in the house. Lack of changes in air temperature indicates ignition problems, and you should seek a professional inspection of the furnace ignitor. Another sign of ignitor problems is when you hear a loud banging noise whenever you switch on the furnace. That could be due to delayed gas ignition, which results from low gas supply, broken pilot lights, too much air mixed with the gas, or misaligned and dirty burners. These problems also need repair by a professional.


Faulty thermostats, ignitor failure, and clogged filters are a few of the many things that could go wrong with your furnace. You should seek professional repair services for proper inspection and fixing of any furnace-related problems.
