Complete Furnace Repair Services

We Fix All Types of Heating Systems

Whether you have a gas furnace that’s not igniting, an oil system with burner problems, or an electric unit that’s not heating properly, we handle all of it. Our service includes diagnosing the root cause, repairing or replacing faulty components, and testing the entire system for safe operation.

Many Milton homes have older heating systems that need specialized knowledge. We work on furnaces from all major manufacturers and can source parts for systems that other companies might write off as “too old.” Regular furnace maintenance and tune-ups are also available to catch small problems before they turn into expensive emergency repairs.

Our Dempsey Comfort Club membership gives you priority scheduling and discounts on repairs and maintenance. It’s designed for homeowners who want to stay ahead of heating problems rather than just react to them when they happen.

How do I know if my furnace needs repair or replacement?

Most furnace problems can be repaired effectively, even on older systems. If your furnace is heating inconsistently, making unusual noises, or causing higher energy bills, a repair usually solves the issue. Replacement typically makes sense when repair costs approach 50% of a new system’s price, or when your furnace is over 15-20 years old and having frequent breakdowns. We’ll give you an honest assessment of whether repair or replacement makes more financial sense for your specific situation.

What should I do if my furnace stops working completely?

First, check your thermostat settings and make sure it’s set to heat mode with the temperature above your current room temperature. Check your circuit breaker to ensure power is reaching the furnace. If you have a gas furnace, make sure the gas valve is turned on. Check and replace your air filter if it’s dirty, as a clogged filter can cause the system to shut down. If these steps don’t restore heat, call for professional repair service. Don’t attempt to fix electrical or gas components yourself.

How long does a typical furnace repair take?

Most common furnace repairs take 1-3 hours to complete. Simple fixes like replacing a faulty thermostat, ignitor, or blower motor can often be done in an hour or less. More complex issues involving heat exchangers, gas valves, or control boards may take several hours. We carry common replacement parts on our service trucks, so most repairs can be completed during the initial visit. If a special-order part is needed, we’ll explain the timeline and can often provide temporary solutions to keep you comfortable.

Is it worth repairing an older furnace or should I replace it?

A well-maintained furnace can run reliably for 15-20 years or more. If your system is under 15 years old and the repair cost is reasonable, fixing it usually makes sense. For older systems, consider the repair cost versus remaining lifespan. If you’re spending several hundred dollars annually on repairs, or if major components like the heat exchanger need replacement, a new furnace might be more cost-effective. We’ll help you weigh repair costs against the benefits of a new, more efficient system.

Can I prevent furnace breakdowns with regular maintenance?

Regular maintenance significantly reduces the likelihood of unexpected breakdowns and extends your furnace’s lifespan. Annual tune-ups include cleaning components, checking electrical connections, testing safety controls, and replacing filters. This preventive approach catches small problems before they cause system failures. Most emergency calls we receive could have been prevented with routine maintenance. Our Dempsey Comfort Club includes scheduled maintenance visits and priority service, helping you avoid the inconvenience and expense of emergency repairs.

What's the difference between gas and oil furnace repairs?

Gas and oil furnaces have different components and potential issues. Gas furnaces commonly need ignitor replacements, gas valve repairs, or heat exchanger inspections. Oil furnaces typically require burner maintenance, fuel pump repairs, or oil filter changes. Both systems share similar components like blower motors, thermostats, and ductwork. Our technicians are trained on both fuel types and carry parts for gas and oil systems. The diagnostic process is similar, but the specific repairs and maintenance requirements vary based on your fuel source and furnace model.
