Furnace repair & maintenance you can trust
Keep your furnace running safely and efficiently with expert repairs and tune-ups.
Whether your furnace has stopped working entirely or you simply want to prevent problems before they start, our certified technicians diagnose and fix issues quickly and honestly. And with a Summers & Smith maintenance plan, you can keep your system running at peak performance while catching small problems before they become expensive emergencies.
Signs your furnace needs service
Furnaces rarely fail without warning. Catching the early signs of trouble can save you from an inconvenient mid-winter breakdown and a much larger repair bill. If you notice any of the following, it's worth booking a service call.
- Unusual noises like banging, rattling, or squealing
- Short cycling, turning on and off frequently
- Uneven heating or cold spots throughout your home
- A yellow instead of blue burner flame
- Rising energy bills without a change in usage
- A furnace that's more than 15 years old
The value of preventative maintenance

The majority of no-heat emergencies we're called out for could have been prevented with regular maintenance. A professional tune-up cleans and inspects the components most likely to fail, verifies safe operation, and keeps your furnace running at the efficiency it was designed for.
Annual maintenance also protects your manufacturer warranty, most warranties require documented yearly servicing, and it gives our technicians a chance to flag worn parts before they leave you in the cold.
Honest, transparent repairs
When something does go wrong, you deserve a straight answer. Our technicians diagnose the real problem, explain your options clearly, and give you an upfront price before any work begins. We'll never pressure you into a replacement you don't need, and if a repair is the smarter choice, we'll tell you.
