Everything Your HVAC System Needs

We handle emergency repairs when your heating system won’t turn on during a February cold snap or your AC stops working during a summer heat wave. Our technicians know how to diagnose problems quickly and get your system running again.

For installations, we help you choose the right system size and efficiency level for your home and budget. Massachusetts weather demands reliable equipment, so we focus on systems that can handle our climate extremes without constant breakdowns.

Regular maintenance through our Dempsey Comfort Club catches small problems before they become expensive emergencies. We clean, inspect, and tune up your system so it runs efficiently and lasts longer. Bristol County homeowners know that preventive maintenance saves money compared to emergency repairs, especially when you’re dealing with our harsh winters and humid summers.

We understand that HVAC emergencies don’t wait for convenient times. When your heating system fails during a winter storm or your AC quits during a heat wave, you need fast response. We prioritize emergency calls and work to get a technician to your home as quickly as possible, often the same day. Our goal is to restore your comfort before the situation becomes dangerous or unbearable. Dempsey Comfort Club members get priority scheduling, which means even faster response times during peak emergency periods.
If your AC is blowing hot air, first check that your thermostat is set to cooling mode and the temperature is set lower than the current room temperature. Check your air filter—a severely clogged filter can cause this problem. If these simple steps don’t fix it, you likely have a refrigerant leak, a failed compressor, or electrical issues that need professional diagnosis. Don’t keep running the system if it’s not cooling properly, as this can cause additional damage and higher repair costs. Call us for proper diagnosis and repair.
Several issues can prevent your heating system from starting. Check that your thermostat has power and is set to heat mode with the temperature set higher than the current room temperature. Make sure your circuit breaker hasn’t tripped and that your furnace switch is on. If you have a gas system, ensure the pilot light is lit. Clogged air filters can also prevent startup. If these basics don’t solve the problem, you’re likely dealing with ignition problems, sensor failures, or other mechanical issues that require professional repair to avoid safety hazards.
Massachusetts weather puts extra stress on HVAC systems, so regular maintenance is crucial. We recommend professional service twice per year—once before heating season and once before cooling season. This schedule catches problems before they cause system failures during extreme weather. Regular maintenance includes cleaning, inspection, filter replacement, and performance testing. Our Dempsey Comfort Club handles this scheduling automatically and provides priority service. Well-maintained systems last longer, run more efficiently, and are far less likely to break down when you need them most.
Proper system sizing depends on your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. Massachusetts homes need systems that can handle both frigid winters and humid summers efficiently. An oversized system will cycle on and off too frequently, wasting energy and failing to control humidity properly. An undersized system will run constantly and struggle to maintain comfortable temperatures. We perform detailed load calculations to determine the right size for your specific home, ensuring optimal comfort and efficiency year-round.
Consider replacement if your system is over 15 years old, requires frequent repairs, struggles to maintain comfortable temperatures, or causes dramatically higher energy bills. If repair costs exceed 50% of a new system’s cost, replacement usually makes more financial sense. However, newer systems with isolated problems often just need professional repair. We’ll give you an honest assessment of your system’s condition and help you understand the costs and benefits of repair versus replacement. Our goal is to recommend the option that makes the most sense for your situation and budget, not push unnecessary sales.
