A functional furnace keeps the indoor temperatures at a comfortable and cozy level. Although your furnace is designed to have an extended service life, it may sustain unnoticeable problems since it operates in the background. Therefore, if you notice that the temperatures are quite low in the winter, hire a furnace technician to diagnose your unit and fix it for improved heating capacity. Below are the issues that you may encounter with a furnace. 

Thermostat Issues

A furnace's thermostat regulates the indoor temperature by displaying the current room temperature and allowing you to set it to your preferred level. Therefore, if your thermostat is faulty, it will erroneously detect temperatures, causing the furnace to blow poorly warmed air. In addition, if there is a huge difference in temperature between your thermostat setting and the outdoor temperature, your thermostat may fail to reach the set levels. A furnace expert must replace the thermostat if it malfunctions and advises you on the appropriate thermostat setting.

Short-Cycling

As your heating system warms your home, it turns on and off to reach your set temperature. The duration of the cycles depends on the programmed setting and the outdoor temperature. Unfortunately, if your furnace powers on and off repeatedly within short bursts of time, it will fail to reach the set temperature. This results from insufficient airflow in the heating unit, causing it to overwork to cool your home. Such an occurrence will cause the furnace to overheat, triggering the safety switch. Therefore, you should contact a furnace professional to clean the air filters for sufficient airflow to prevent overheating.

A Noisy Furnace

Typically, a furnace will make some noise as it operates; for instance, it will click when the thermostat attains a specific temperature. Depending on the furnace type, the blower may be louder than others. However, if your heating unit produces strange and loud noises, a component is experiencing a malfunction. For example, grinding noises mean the blower wheel is worn out with unlubricated bearings, while persistent whistling means the air filter is clogged. When you hear weird noises from your heating appliance, contact a furnace technician to ascertain the exact cause of the malfunction and resolve it.

Furnace Leaking Water

The combustion process produces a lot of water vapor that is vented to a cool exhaust feature. This water routes to the drain pan through condensation pipes. However, if the lines spring a leak or clog, a water backup in the system may cause water to spill, forming puddles around the unit. Moreover, if the drain pan cracks, it may cause water to spill beneath the heating unit.

If you regularly service your furnace, it will perform efficiently without inconvenience. Therefore, schedule routine maintenance to keep your heating system in peak condition and prevent underlying issues from escalating.
