Need a furnace repair company near you? Reliance provides furnace repair in Sudbury. If your furnace has stopped heating, is making an unusual noise or is not working properly, our licensed heating technicians can diagnose the problem and explain the recommended repair.
When to Call for Furnace Repair
A furnace that will not turn on, blows cool air, heats unevenly or keeps turning on and off may need professional attention. Different problems can cause similar symptoms, so a technician needs to inspect the system before recommending a repair.
You can start with the safe checks in the “Does Your Furnace Need Repair?” section below. If those checks do not restore heat, call Reliance rather than attempting to work on the furnace’s gas, electrical or internal components.

Why Choose Reliance?
Your furnace troubleshooting checklist
Reliance Home Comfort™ is always just a phone call away in a home heating emergency. But sometimes, getting more heat to blow into your home is as simple as flicking a switch. Here are five things you can check before you give us a call. They may just save you the cost and inconvenience of an unnecessary house call.
- Check your thermostat setting. Is it on ‘heat’? You’d be surprised how easy it is to forget to make the change when the temperature drops.
- Check your furnace unit and make sure it’s turned on. You should find the switch on a nearby wall.
- Check your home’s breaker panel. Is the circuit breaker marked ‘furnace’ in the correct position?
- Check your furnace’s outdoor air vents. You’ll find these on the exterior of your home. Make sure they aren’t blocked by snow, ice, debris, or a nesting animal. (A thorough furnace vent inspection should be left to a professional.)
- Check your furnace filter. Most should be changed every three months or according to the recommendations of your equipment manufacturer. If you have 4- or 5-inch media filters, they can be changed every 6 months to a year, depending on manufacturer specifications.

- Create a clear space around your furnace or boiler.
- Schedule an annual furnace inspection and tune-up.
