Your gas heater breaking down isn’t just inconvenient—it’s urgent. Especially when coastal Massachusetts temperatures drop into the single digits and your family’s comfort and safety are on the line.
That’s exactly why we built our gas heater repair service around what you actually need: fast response, skilled technicians, and transparent pricing. No runaround, no surprises, just your heat restored quickly and safely.
When we finish your repair, you’re not just warm again—you’re confident your system is running efficiently and safely. You know exactly what was wrong, what we fixed, and what it cost before we started the work.
Dempsey Energy started as a small family oil company right here in Plymouth County. We’ve been keeping Mattapoisett homes warm for over three decades, so we know exactly what coastal winters can throw at your heating system.
Our NATE-certified technicians aren’t just skilled—they understand the unique challenges of heating homes near the coast. Salt air, temperature swings, and those brutal nor’easters that can knock out power for days.
We’re the team your neighbors call when their gas heater quits at 2 AM or when they want maintenance that actually prevents problems instead of just fixing them after they happen.
First, we diagnose the problem completely. Our technicians inspect your entire gas heating system—not just the obvious issue. We check the ignition system, gas connections, heat exchanger, and airflow to understand what’s really going on.
Next, we explain exactly what needs fixing and provide upfront pricing before we touch a single component. No work starts until you approve both the repair plan and the cost.
Finally, we complete the repair using quality parts designed for your specific system. We test everything thoroughly—ignition, gas flow, heat output, and safety systems—to make sure your heater is running properly and safely before we consider the job finished.

Every gas heater repair includes a full system inspection, not just a quick fix. We examine flame sensors, gas valves, ignition systems, and heat exchangers to catch potential problems before they leave you without heat.
Mattapoisett’s coastal climate demands reliable heating systems. Between the salt air that can corrode components and temperature swings that stress your equipment, your gas heater works harder than systems inland. That’s why our service includes checking for corrosion, testing safety systems, and ensuring your unit can handle whatever Massachusetts weather brings.
You also get our maintenance plan options, emergency service availability, and the peace of mind that comes from working with technicians who’ve been serving Plymouth County families for over 30 years.

For urgent but non-emergency repairs—like reduced heat output or unusual noises—we can usually schedule service within 24 hours.
Every gas heater repair includes a complete system inspection, not just fixing the immediate problem. We examine your ignition system, gas connections, heat exchanger, flame sensors, and ventilation to ensure everything is operating safely and efficiently.

Call for repair if your gas heater is less than 15 years old and the repair cost is less than half the price of a new unit. Signs that repair makes sense include isolated problems like a faulty thermostat, dirty flame sensor, or worn ignition component.
Consider replacement if your gas heater is over 20 years old, requires frequent repairs, or if repair costs exceed 50% of a new unit’s price. Also consider replacement if your heating bills have increased significantly or if your system can’t maintain comfortable temperatures.
We’ll always give you honest advice about whether repair or replacement makes more financial sense. Our goal is solving your heating problem in the most cost-effective way, not selling you services you don’t need.
Safety is our top priority with every gas heater repair. We test for gas leaks using electronic detection equipment, inspect all gas connections and fittings, and verify proper combustion and ventilation.
We also check your carbon monoxide detectors, examine the heat exchanger for cracks or corrosion, and test all safety controls including flame sensors and gas valves. These safety systems are designed to shut down your heater if dangerous conditions develop.
After completing any repair, we perform a full operational test to ensure your gas heater is not only working properly but operating safely. We’ll also explain any safety concerns we find and recommend solutions to keep your family protected.
