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. Emergency repairs, routine maintenance, new installations, and everything in between.

Our Dempsey Comfort Club gives you priority scheduling and regular maintenance that catches problems before they become expensive emergencies. Members get faster response times and the kind of proactive service that keeps systems running longer.

We work on all major HVAC brands and systems. Gas furnaces, heat pumps, central air, ductless systems. If it heats or cools your home, we know how to fix it, maintain it, or replace it when the time comes. And because we also handle plumbing, we can take care of related issues without you having to coordinate multiple contractors.

We offer 24/7 emergency service because HVAC problems don’t wait for business hours. Most emergency calls get same-day response, and our Dempsey Comfort Club members get priority scheduling. When you call with a heating or cooling emergency, we’ll give you a realistic timeframe and stick to it. We understand that losing heat in winter or AC in summer isn’t just uncomfortable – it can be dangerous for your family.
It depends on the age of your system, the cost of repairs, and how often you’re calling for service. Generally, if your system is over 15 years old and repair costs are more than half the price of replacement, it’s time to consider a new system. We’ll give you honest advice based on what we see, not what makes us the most money. Sometimes a repair is the smart choice, sometimes replacement saves you money long-term. We’ll explain both options clearly so you can make the right decision for your situation.
Our maintenance service includes cleaning and inspecting all major components, checking refrigerant levels, testing safety controls, lubricating moving parts, and replacing filters. We also check your ductwork for leaks and test your thermostat calibration. Most importantly, we catch small problems before they become expensive repairs. Regular maintenance typically extends your system’s life by several years and keeps it running efficiently, which saves you money on energy bills.
Yes, we service and repair all major HVAC brands including Carrier, Trane, Lennox, Rheem, Goodman, and others. Our technicians stay current on training for different manufacturers and carry parts for the most common systems. If you have an unusual or older system, we can usually source the parts you need. We’ll let you know upfront if there are any limitations with your specific equipment.
We serve Wrentham and the surrounding Norfolk County communities including Franklin, Norfolk, Plainville, Medway, and nearby areas. We know the local building codes, understand the climate challenges specific to this region, and have built relationships with local suppliers for faster parts availability. Our service area is designed so we can respond quickly to calls and provide consistent service to our established customer base.
Call for emergency service if you have no heat when it’s below 40 degrees, no cooling when it’s above 85 degrees, if you smell gas near your furnace, or if you hear unusual loud noises from your system. Also call immediately if your carbon monoxide detector goes off or if you see ice forming on your AC unit. For less urgent issues like inconsistent temperatures or higher energy bills, regular service scheduling is fine. When in doubt, call us – we’ll help you determine if it’s truly an emergency.
