So it’s cold outside and the gas heater is not turning on. Yes, you have a problem. If your heater breaks down during winter, then it’s time for you to call an HVAC expert. But before the guys show up, you must first endure a world of discomfort. Before this nightmare scenario happens, it’s useful to understand why gas heaters stop working in the first place. What are the common causes of gas heater failure? Knowing these causes can help you to avoid having problems with your gas heater in the future. It can help you to save time and money too.
1) You’re not regularly maintaining your system
If there’s a problem with your gas heater then a possible reason could be lack of maintenance. It’s actually the number one reason why homeowners call gas heater service during the winter. If you have not been properly maintaining your gas heater, then it’s probably very dirty already. And dirt can affect its performance, particularly of the blower motor. If the blower motor is dirty, then it won’t be able to deliver enough cool air to the heat exchanger. This can lead to overheating and eventual breakdown of your gas heater. Dirty air filters can also cause a lot of problems. To avoid having these problems, you should call an expert to clean your system at least once a year. Regular gas heater maintenance can help you to avoid more costly repair work.
2) Your heater is burning too much gas
Another possible reason why your gas heater is not turning on is that it’s burning too much gas. Furnaces have specific requirements when it comes to the amount of gas they should burn. During installation, you need to calibrate the equipment to make sure that it’s working properly. If you fail to do this then there is a chance that your gas heater will stop working unexpectedly. This is because a gas heater that has not been calibrated properly burns too much gas. This can lead to you overpaying for gas during the winter. And it can also lead to overheating of the furnace that can then cause it to cycle on a limit switch. A combustion analysis performed by an expert can determine if your gas heater is burning too much gas.
3) Your heater is not installed properly
It’s important that your heating system is installed properly. And this includes having proper ductwork. Because sometimes, when a heating system fails to work, it’s not really the system that has a problem but improper ductwork. This is why it’s important to call the right company to install your heating system for you. There are companies that cut corners to save time when installing ducts. If it’s a good enough job, the heater may still work. But if the installation job is really bad, you won’t achieve proper airflow throughout your home. This could also lead to your furnace short cycling more often. Your system will overheat over time and one day it will just stop working.
