How quickly can you respond to HVAC emergencies in Randolph?

What's included in the Dempsey Comfort Club membership?

The Dempsey Comfort Club provides regular maintenance visits to keep your HVAC system running efficiently and catch potential problems before they become expensive repairs. Members get priority scheduling, which means faster response times when you need service. The program is designed for homeowners who want to take a proactive approach to their HVAC system rather than waiting for breakdowns. Specific benefits and pricing details are discussed when you inquire about membership.

Do you work on all brands of HVAC equipment?

Yes, we service all major HVAC brands and most residential heating and cooling systems. Our technicians have experience with furnaces, heat pumps, central air systems, ductless mini-splits, and boilers from manufacturers like Carrier, Trane, Lennox, Rheem, and others. Whether you need repairs on an older system or maintenance on newer equipment, we have the tools and knowledge to handle the work properly.

How do I know if I need HVAC repair or replacement?

Age, efficiency, and repair frequency are the main factors. Systems over 15 years old that need frequent repairs or aren’t keeping your home comfortable may be better candidates for replacement. Rising energy bills, uneven heating or cooling, and constant cycling on and off are also signs your system isn’t working efficiently. Our technicians can evaluate your current system’s condition and help you understand whether repair or replacement makes more financial sense for your situation.

What should I expect during an HVAC service call?

Our technician will first listen to your description of the problem, then inspect your system to diagnose the issue. You’ll get a clear explanation of what’s wrong, what needs to be fixed, and what it will cost before any work begins. We’ll test the system after repairs to make sure everything is working properly and explain any maintenance steps you can take to prevent future problems. The goal is to leave you with a working system and a clear understanding of what was done.

Do you provide estimates for new HVAC system installations?

Yes, we provide detailed estimates for new installations after evaluating your home’s heating and cooling needs. The estimate process includes measuring your space, assessing your current ductwork, discussing your comfort preferences and budget, and recommending appropriate equipment options. You’ll receive a written estimate that breaks down equipment costs, installation work, and any additional components needed. This gives you the information you need to make an informed decision about your new HVAC system.
