Common signs include uneven heating, strange noises, increased energy bills, frequent cycling, or a complete lack of heat. If you notice any of these issues, it's best to schedule a professional inspection.
2. How often should I have my furnace serviced?
We recommend scheduling annual maintenance before the colder months to ensure your furnace runs efficiently and prevent unexpected breakdowns. Regular servicing can also extend the lifespan of your system.
3. What should I do if my furnace stops working?
First, check your thermostat settings, air filter, and circuit breaker. If everything appears normal but the furnace still won’t turn on, contact a professional for a thorough inspection and repair.

The duration of a repair depends on the issue. Most common repairs can be completed within a few hours, but more complex problems may require additional time or parts. Our technicians strive to restore your heat as quickly as possible.

If your furnace is over 15 years old and frequently breaking down, replacement may be more cost-effective in the long run.

Our experts can assess your furnace and provide the best recommendation based on its condition.
