Everything Your System Needs

Whether your heating system won’t turn on, your AC is blowing hot air, or you need a complete system replacement, we handle it all. Our technicians work on all major brands and system types.

Regular maintenance keeps small problems from becoming expensive emergencies. We’ll check your system’s efficiency, replace filters, clean components, and catch potential issues before they leave you without heat or air conditioning.

For Swansea homeowners dealing with older systems, we’ll give you honest advice about repair versus replacement. Sometimes a simple fix gets you several more years. Other times, a new efficient system saves you money long-term.

We prioritize emergency calls, especially during extreme weather when your heating or cooling system failure affects your family’s safety and comfort. Most emergency calls in the Swansea area get same-day service, and we often have technicians available within a few hours. During peak seasons like the middle of winter or summer heat waves, response times may be longer, but Dempsey Comfort Club members get priority scheduling. We’ll always give you a realistic timeframe when you call and keep you updated if anything changes.
First, check your thermostat settings and make sure it’s set to heat mode with the temperature set higher than the current room temperature. Check your circuit breaker to see if it’s tripped, and make sure your furnace filter isn’t completely clogged. If you have a gas system, ensure the pilot light is lit. If none of these simple checks solve the problem, call us for service. Don’t attempt to repair gas connections or electrical components yourself. While you’re waiting for service, use safe alternative heating methods and keep interior doors open to circulate whatever warm air remains in your home.
Several factors help determine repair versus replacement. If your system is over 15 years old and needs frequent repairs, replacement often makes more financial sense. High energy bills, uneven heating or cooling, and constant cycling on and off are signs your system is struggling. When repair costs exceed 50% of a new system’s cost, replacement is usually the better investment. Our technicians will assess your system’s condition, explain your options honestly, and help you make the decision that works best for your budget and long-term comfort needs.
Yes, our technicians are trained to work on all major HVAC brands including Carrier, Trane, Lennox, Rheem, Goodman, York, and many others. We stock common parts for most systems and can usually complete repairs the same day. For older or less common brands, we may need to order specific parts, but we’ll explain the timeline upfront. Our experience with thousands of Bristol County homes means we’ve seen virtually every type of system and know the common issues with each brand and model.
Our maintenance service includes a complete system inspection, cleaning of key components, filter replacement, and testing of all safety controls. We check refrigerant levels, inspect electrical connections, clean condenser coils, and test thermostat operation. For heating systems, we inspect the heat exchanger, clean burners, and check venting systems. You’ll receive a detailed report of our findings and recommendations for any issues we discover. Dempsey Comfort Club members get additional benefits including priority scheduling, discounts on repairs, and extended warranties on our work.
Regular maintenance is the biggest factor in system efficiency. Clean filters, properly calibrated thermostats, and well-maintained equipment can reduce energy costs by 15-20%. Programmable or smart thermostats help by automatically adjusting temperatures when you’re away. Sealing air leaks around windows, doors, and ductwork prevent your system from working harder than necessary. If your system is older, upgrading to a high-efficiency model can significantly reduce energy costs. We can assess your current system’s efficiency and recommend improvements that make sense for your home and budget.
