Understanding Your Heater
To troubleshoot effectively, it’s essential to understand what type of heater you have, as issues can vary significantly based on the technology used.
Types of Heaters
Heaters generally fall into two categories: gas heaters and electric heaters. Each has its mechanisms and common issues, and knowing the specifics can help you diagnose problems more effectively.

Gas Heaters
Gas heaters are popular due to their efficiency and ability to heat up quickly. They function by burning natural gas or propane to produce warmth. However, if the pilot light goes out or there’s an issue with the gas supply, you might find yourself in a cold spot. Regular maintenance can ensure that your gas heater operates safely and efficiently.
Electric Heaters
Electric heaters rely on electricity to generate heat and can be portable or central systems. While they are generally easier to maintain, they can run into electrical problems or circuit issues that might leave you out in the cold. Our team is well-equipped to handle any electrical maintenance your heating system might need.
Common Reasons Your Heater Might Not Work

If your heater is acting up, it’s essential to identify the potential causes. Here are some of the most common reasons your heater might not be working as it should,, check out this article on When Your Heater Fails: 6 Reasons Why.
Thermostat Issues
The thermostat is the brain of your heating system. If it’s not functioning correctly, your heater may not respond. This could be due to incorrect settings, dead batteries (if it’s digital), or even a malfunctioning unit. Make sure to check the settings first; sometimes, it’s as simple as forgetting to turn it on!
Power Supply Problems
For electric heaters, ensure that it’s plugged in and that the circuit breaker hasn’t tripped. A blown fuse or tripped circuit can stop your heater from working altogether. If everything appears normal but your heater is still not functioning, you may need to dig deeper into electrical issues.
Air Filters and Blockages
Dirty air filters can restrict airflow, leading to overheating and causing your heater to shut down. Regularly check and replace your air filters to ensure optimal performance. A clean filter can significantly improve airflow and efficiency.
Pilot Light or Ignition Issues
For gas heaters, the pilot light is crucial. If it goes out, your heater won’t ignite. This can happen due to a draft or a problem with the gas line. If you notice the pilot light is out, follow the manufacturer’s instructions to relight it. If you smell gas, evacuate immediately and call a professional.

Ductwork and Vents
Blocked ducts or vents can lead to uneven heating or complete failure of your heating system. Check for any obstructions such as furniture, dust, or debris. Ensuring that ducts are clean and unobstructed can significantly improve airflow and heater performance.
Quick Fixes for a Heater Not Working

Before you call in the professionals, there are several quick fixes you can try at home. Let’s explore some simple steps you can take to possibly resolve the issue.
Check the Thermostat Settings
Start by checking the thermostat settings. Ensure it’s set to “heat” and that the desired temperature is higher than the current room temperature. It’s an easy mistake to make, so don’t overlook this vital step!
Ensure Power Supply
For electric heaters, check the power supply. Ensure that the heater is plugged in, and inspect the circuit breaker. If there’s an issue, reset the breaker and see if that solves the problem.
Clean or Replace Air Filters
A dirty air filter can cause significant problems for your heater. If you haven’t changed your air filter in a while, now is the time to do it. Cleaning or replacing it can improve airflow and efficiency dramatically.
Inspect the Pilot Light
For gas heaters, check the pilot light. If it’s out, you’ll need to relight it. Follow the manufacturer’s instructions for relighting the pilot. If the pilot light keeps going out, there might be a bigger issue that requires professional attention.
Clear Ducts and Vents
Make sure that all ducts and vents are free of dust and debris. A blocked duct can severely impact your heater’s efficiency. A quick vacuum around the vents can make a significant difference in airflow.
Regular Maintenance Tips
To avoid heating issues in the future, regular maintenance is key. Here are some tips to keep your heater running smoothly:
- Schedule annual maintenance checks with a professional.
- Clean your heater regularly and keep it free of dust.
- Replace air filters every one to three months, depending on usage.
- Check for any signs of wear and tear, and address them promptly.
