Heating Services: 3 Reasons Why Your Heating Unit Will Not Turn On

You require a working heater when trying to brave the cold season. Since winter comes only once a year, it is common for homeowners to forget about maintaining their heating units for the rest of the year. Consequently, many people end up with heating emergencies that are preventable in the middle of the cold season. By learning about the common reasons why your heating unit might fail to turn on, you can figure out how to make it work for you. Here are the top five causes of the system failure. 

Poor DIY System Maintenance

Poor DIY maintenance is one of the common reasons why heating systems fail. Often, people make emergency calls to the heating repair experts for minor issues that you can solve by cleaning the heating unit. For example, dirt in the blower motor is known to cause overall system malfunction. A heat exchanger malfunctions if the blower motor is full of junk and debris. The grime prevents air from moving across the unit, eventually leading to system breakdown. Dirty air filters are another common issue because they stop the airflow that should aid proper combustion. Other parts of the system to clean include dirty flame sensors and burners. Regular cleaning eliminates all the issues that typically result from dirty systems. 

Excessive Gas

Sometimes the system fails because it holds more gas than the recommended capacity. System manufacturers set a limit on the amount of gas their units should burn. You should calibrate the equipment during the installation process and ensure it holds the right gas volume. A professional can perform an annual combustion analysis on your system to determine whether the designers calibrated it. If not, they will know how to fine-tune it and achieve optimal heating efficiency. 

When the Blower Capacitor Dies

The blower capacitor is another crucial component of the heating system. It resembles a big battery. Its function is to turn on the furnace when you change the settings on your thermostat. Capacitors have tolerance levels. When yours reaches the optimum tolerance level, it fails. It is advisable to repair the system as soon as you notice signs of malfunction. Once the capacitor fails, it might damage the blower, and fixing the resulting damage can get costly. Speak to a technician immediately if your blower starts behaving abnormally.

These are some of the common causes of heating system failure. It is advisable to speak to a competent heating service technician to look at yours and determine whether you need to repair or replace it. They will help you restore your unit to optimal functionality.
