Frequently Asked Questions
What are the signs that my furnace needs repair?
If you notice strange noises, uneven heating, higher energy bills, or a yellow pilot light, it’s time to schedule a furnace repair. These are signs your system may be struggling.
How long does a furnace repair take?
Most furnace repairs can be completed within a few hours. We aim to provide same-day service whenever possible, so your home stays warm without long delays.
What should I do if my furnace stops working suddenly?
Check your thermostat settings, circuit breaker, and air filter first. If everything looks fine but the furnace still won’t start, give us a call for immediate assistance.
Is it worth repairing an old furnace?
It depends on your system’s age and the repair cost. If repairs exceed half the price of a new furnace, replacement might be the better option. We’ll help you decide what makes sense.
How can I prevent future furnace problems?
Schedule regular maintenance at least once a year. Changing filters, keeping vents clear, and having professional inspections help prevent breakdowns and extend your furnace’s lifespan.
