A furnace offers you a comfortable home during winter, as it helps you achieve much-needed warmth. Unfortunately, the heating unit can malfunction due to wear and tear or lack of maintenance. This can lead to system breakdowns requiring costly repairs. So when your heating system demonstrates signs of failure, call a furnace repair technician right away. They will inspect and fix the malfunction to ensure you receive maximum heating output. This guide shares a few common furnace problems and how a furnace repair technician can help you fix them. 

Pilot Light Issues

Older furnaces use a pilot light to ignite the burner. However, dirt can accumulate on the thermocouple, hindering electricity from reaching it. This hinders the gas supply, turning off the pilot light. In addition, the thermocouple can bend due to mechanical stress, preventing current flow. And, if you place your thermostat in a location with inadequate combustible air, the pilot light will go off. In that case, you should hire an HVAC professional to clean the thermocouple. They will also place the furnace in a location with constant airflow to ensure proper ignition.

Problems with the Thermostat

The thermostat will allow you to set your preferred temperature range by displaying the current room temperature. Despite that, the wrong temperature settings can cause your system to malfunction. For example, a huge discrepancy between the set and room temperatures will cause the furnace to run constantly. Additionally, the wrong calibration on the thermostat causes the unit to reach the set temperature too fast. As a result, the furnace will short cycle, causing uneven heating. Thus, you ought to contact a repair expert to rectify the calibration, ensuring maximum indoor climate control.

Clogged Filter

Furnace filters collect dust, hair, debris, and other airborne particulates, keeping them out of circulation. When obstructed, the fan operates much harder to draw adequate air, which causes it to overheat. Furthermore, dirt will bypass clogged filters and gunk up in the heat exchanger, compromising its operation.

Gas Leaks

If you notice a rotten egg smell, gas could be leaking into your home. This issue can result from the gradual degradation of the gas lines. Additionally, deep excavation or root infiltration near your house can damage utility lines, leading to gas leakages. Gas leaks usually produce a rotten egg smell. This unique smell comes from mercaptan added to natural gas to make it distinct. If you detect an unusual odor, hire a heating repair expert to fix the gas leaks immediately.

A malfunctioning furnace will compromise your indoor comfort and spike your energy expenses. Therefore, contact an HVAC technician for heating repairs if you notice an abnormality in your heating unit.
