You don’t have to be an HVAC expert to know you have a problem when your furnace needs maintenance. But, before you start reaching for your wallet and stressing out about major repairs or replacement, consider these five furnace troubleshooting tips. They could save you time and money and turn a catastrophe into a minor inconvenience:


1. Check your thermostat.

2. Change the filter.

3. Check the breaker.

4. Find the “other” switch.

5. Verify the Light and Gas.


Furnace maintenance are complicated devices, often requiring a certified expert when they need repair. But sometimes the problem is small and can be handled in a few minutes when you are armed with the right information. Take the time to become familiar with your HVAC unit. Know where your breakers, disconnects, and shut off valves are located. Spend a minute with your thermostat to understand how it can be a benefit to your energy conservation. And, perform routine furnace maintenance, such as changing your filters once every month, to prevent unnecessary failures and keep your furnace running strong. Controlling the indoor climate was not an option a few decades back, and this left our possessions at the mercy of the elements. In truth, our insurance coverage could now decline if we choose to live without the services provided by our ‘old faithful’ HVAC system.

During a furnace maintenance inspection, a technician should attend to these 10 things:

1. Confirm the refrigerant is at the right level.
2. Remove any surplus to a separate container.
3. Top up the refrigerant if there is not enough.
4. Check for any leaks causing this discrepancy.
5. Make sure the thermostat is accurate.
6. Measure the airflow through the evaporator coil.
7. Test for leaks in any ducting system.
8. Check the operating system is working correctly.
9. Visually examine electrical connections.
10. Lubricate electric motors and check belts.
