Everything Your System Needs

Emergency repairs when your system fails unexpectedly. Routine maintenance to catch problems before they leave you without heat or AC. Full system replacements when repair costs don’t make sense anymore.

New England weather is hard on HVAC equipment. Furnaces work overtime during long winters. Air conditioners struggle through humid summers. Regular maintenance keeps everything running efficiently and helps you avoid emergency calls during the worst weather.

The Dempsey Comfort Club gives you priority scheduling and regular maintenance visits. Your system gets checked before problems develop, and you get faster service when you need repairs.

Emergency response times depend on the season and current call volume, but most emergency calls get same-day service. During extreme weather when everyone’s systems are struggling, it might take longer, but Comfort Club members get priority scheduling. The best approach is calling as soon as you notice a problem rather than waiting until your system completely fails. Early intervention usually means faster service and lower repair costs.
A complete maintenance visit includes cleaning or replacing filters, checking electrical connections, testing safety controls, lubricating moving parts, and inspecting the heat exchanger or evaporator coils. Our technician also checks refrigerant levels on AC units and tests thermostat calibration. You get a report on what was done and any issues that need attention. Regular maintenance typically prevents about 80% of emergency breakdowns and keeps your system running efficiently.
Yes, Dempsey Energy services all major HVAC brands including older systems that other companies might not want to touch. Whether you have a high-end system or basic builder-grade equipment, the diagnostic and repair process is the same. Some older systems might need special-order parts, which can extend repair time, but most common problems can be fixed with standard parts that we keep in stock on our service trucks.
The general rule is if repair costs exceed half the value of your system, replacement makes more financial sense. Age matters too – systems over 15 years old often need frequent repairs that add up quickly. Our technician will give you honest recommendations based on the specific problem, your system’s age and condition, and what similar repairs typically cost. You’ll get options for both repair and replacement so you can make the decision that works for your budget.
First, check your thermostat settings and make sure it’s set to heat mode at the right temperature. Check your circuit breaker to see if it tripped. Look at your furnace filter – a completely clogged filter can shut down the system. If those basics don’t solve it, don’t keep trying to restart the system. Repeated restart attempts can cause more damage. Call for service and let a technician diagnose the real problem safely.
This usually means your outdoor unit isn’t working while the indoor fan keeps running. Common causes include a tripped breaker for the outdoor unit, a bad capacitor, low refrigerant from a leak, or a failed compressor. Don’t ignore this problem – running the system when it’s not cooling properly can damage expensive components. Turn off the system and call for service. A technician can diagnose whether it’s a simple fix or something more serious that needs immediate attention.
