Emergency heating repairs when your furnace stops working in the middle of winter. AC installation and repair for systems that actually cool your home efficiently. Comprehensive maintenance plans that catch small problems before they become expensive emergencies.

Scituate’s coastal environment is tough on HVAC equipment. Salt air corrodes components faster, and humidity puts extra strain on cooling systems. Our maintenance includes the specific checks and cleaning your system needs to handle these local conditions.

The Dempsey Comfort Club gives you priority service, regular tune-ups, and member discounts on repairs. It’s designed for homeowners who want their systems maintained properly instead of waiting for things to break.

Dempsey Energy provides 24/7 emergency response for heating and cooling failures. During winter heating emergencies, our goal is same-day service because losing heat in a New England winter isn’t just uncomfortable—it can damage your home’s plumbing and create safety issues. Emergency calls get priority dispatch, and our technicians carry common repair parts to handle most problems on the first visit. Dempsey Comfort Club members receive priority scheduling for both emergency and routine service calls.
First, check your thermostat settings and make sure it’s set to heat mode with the temperature above your home’s current temperature. Verify the circuit breaker hasn’t tripped and replace the air filter if it’s dirty—a clogged filter can cause safety shutdowns. Check that your furnace switch is on and gas supply is connected if you have a gas system. If these basic checks don’t solve the problem, call for professional diagnosis. Heating system failures can involve gas connections, electrical components, or mechanical parts that require proper tools and expertise to repair safely.
HVAC systems in Scituate and coastal areas need maintenance twice yearly—spring AC tune-ups and fall heating system service. The salt air and high humidity near the coast accelerate corrosion and put extra strain on components, making regular maintenance even more critical than inland areas. During maintenance visits, our technicians clean coils affected by salt air, check for corrosion, test safety controls, and replace filters. This preventive approach catches problems early and extends equipment life in harsh coastal conditions. Most manufacturers require regular professional maintenance to keep warranties valid.
Several issues can cause an AC system to blow warm air instead of cooling. Low refrigerant levels from leaks prevent proper cooling, while dirty evaporator coils can’t absorb heat effectively. A malfunctioning compressor, clogged air filter, or faulty thermostat can also cause this problem. Sometimes the issue is as simple as incorrect thermostat settings or a tripped circuit breaker. However, refrigerant leaks and compressor problems require professional diagnosis and repair. Don’t ignore this issue—running a malfunctioning AC system can cause more expensive damage and leave you without cooling during hot weather.
Comprehensive HVAC maintenance includes cleaning and inspecting all major components, testing safety controls, checking refrigerant levels, and replacing air filters. For heating systems, this means cleaning burners, testing gas connections, inspecting heat exchangers, and verifying proper venting. AC maintenance involves cleaning coils, checking refrigerant pressures, testing electrical connections, and calibrating thermostats. In coastal areas like Scituate, we pay extra attention to components affected by salt air corrosion. Our service includes performance testing to ensure your system operates efficiently and safely, plus identifying potential problems before they cause breakdowns.
Proper HVAC sizing requires a detailed load calculation that considers your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. An oversized system cycles on and off frequently, wasting energy and failing to control humidity properly. An undersized system runs constantly, struggles to maintain comfort, and wears out faster. Our professional technicians use Manual J load calculations to determine the right capacity for your specific home and needs. Factors like Scituate’s coastal humidity and seasonal temperature swings affect sizing requirements, making professional assessment essential for optimal performance and efficiency.
