No-Heat Troubleshooting Tips for Your Boiler
Written on: February 10, 2025
Easy Tips That May Save You a Service Call
There’s nothing worse than suddenly noticing it’s unusually cold in your home, and that sinking feeling as you realize your heat is off. Especially in the middle of the night. Of course, we’re always here for you. The expert team at Marandola can get you up and running fast. But sometimes when your boiler is on the fritz, there could be an easy fix that you can handle yourself – so you can avoid the expense of a service call, especially at night—and free up our techs to help others.
Common Sources of Problems
Try these troubleshooting steps before you call:
- Check Your Thermostat
Make sure your thermostat is set to a temperature at least 5° above room temperature and set to “heat.” Is it the batteries? Try installing fresh ones.
- Check the System Switch
Did the switch for your heating system accidentally get turned off? You’d be surprised how often this is the source of the problem. Don’t overthink it, just turn it on.
- Check Fuses and Circuit Breakers
This is another common cause of a no-heat situation. Circuit breakers can easily trip. Check the breaker that your heating system is on, and turn it on if it’s off.
- Check Your Fuel Supply
If you haven’t checked your tank gauge in a while, there’s a good chance you’ve run out of fuel—especially if it’s been very cold recently, or if you’ve been spending more time at home during the day. If you’re out of heating oil, know that we’re on call 24/7 for emergency deliveries.
- Check the Air Filter
When the air filter on your furnace gets clogged, the system will shut down. Replace it and set a reminder on your calendar to check it once a month.
- Check the Boiler
If you have a steam boiler, check the water level gauge. It should be at least half-full. Call us if it isn’t. Have a hot water boiler? You can skip this step.
- Reset the System
If none of the previous steps work, push and hold the Reset button for 30 seconds. Only do this ONCE. Doing it more than once floods the combustion chamber with too much heating oil. That’s an expensive repair job on top of any other repairs you may need.
If none of these steps resolves the problem, call us and we’ll dispatch a technician to get you up and running as soon as possible.
An Ounce of Prevention
Some heating system problems are easy to prevent, and a tune-up is the best way to make sure your heating equipment is running properly, and at peak efficiency. Good maintenance not only helps keep heating costs down, but also prevents many of the problems that lead to breakdowns. A tune-up can also keep your warranty in effect: Good to keep in mind!
Whether you need an oil-fired equipment repair, or would like to schedule a tune-up, the experts at Marandola are always happy to help—we can even talk you through the steps above if you need moral support! We’re your neighbors, and we care about our reputation in the Litchfield County community. That’s why we go out of our way to exceed your expectations.
