Walpole covers about 21 square miles and has a varied housing stock that reflects its growth over three centuries. In the South Walpole Historic District, you'll find Cape Cods, ranches, and colonials on tree-lined streets with mature landscaping. East Walpole, near the landmark Francis William Bird Park, has a mix of classic single-family homes and some newer development. The downtown area has seen steady investment in recent years, with local shops and restaurants giving the center of town a real neighborhood feel.
Because Walpole has such a wide range of home styles and ages, HVAC needs vary quite a bit from one part of town to another. A 1950s ranch in South Walpole might need a furnace swap and new ductwork, while a recently built colonial off Route 1A could benefit from a high-efficiency heat pump system. We take the time to evaluate each home individually rather than pushing a one-size-fits-all solution. Our services cover everything from straightforward AC repairs to ground-up installations for new construction and major renovations.
At just five miles southwest of Norwood, Walpole is one of our closest service areas. That means shorter response times for emergency calls and easy scheduling for routine maintenance visits. Whether you're prepping your furnace for winter or your central air for a July heat wave, Dalelis has you covered.
When your HVAC system starts making strange knocking, grinding, or loud gurgling noises, it is a clear sign that a component is failing and getting ready to break down. While the unit may still be operational, you should turn it off immediately to prevent further damage. When you hear abnormal noises, reach out to James A. Dalelis Plumbing & HVAC as soon as possible for urgent diagnostics.
If your HVAC system is blowing cold air in the winter while the heater is on, or hot air in the summer when the AC is on, it's time to reach out for emergency HVAC repair. When your system is pushing out air that matches the temperature outside, you're likely dealing with blocked airflow or a broken compressor. Contact James A. Dalelis Plumbing & HVAC and our team will inspect and repair your system right away.
If cool or warm air is only trickling from your vents instead of blowing with full force, it signals that the system is struggling and requires emergency HVAC repair. Weak airflow is typically a sign of components that are malfunctioning or completely worn out. Issues like clogged air filters, dirty coils, failing blowers, or obstructions in the ductwork could cause this problem. If your HVAC system is giving out weak air flow, contact James A. Dalelis Plumbing & HVAC right away.
It's normal for HVAC systems to run more frequently during extreme temperatures, but the time between cycles should stay roughly consistent. If your HVAC system is turning on or off more often than usual, you're likely dealing with a serious issue that needs emergency repair or even replacement. Contact James A. Dalelis Plumbing & HVAC for emergency HVAC services.
If your home is becoming increasingly hot during a summer heatwave, or if your furnace fails to provide heat during a Massachusetts cold snap, you are likely facing an HVAC emergency. In these moments, it is important to take two simple, immediate steps:

Fast, efficient, and professional. I went to turn my heat on and realized my boiler wasn’t working. It was a Friday before a long holiday weekend but James had one of his guys there first thing Monday morning and my heat was back up and running in just a few hours! Thank you so much!! Highly recommend
Met with me on short notice and took the time to talk about all options, but brief and to the point.
Helped me make a better decision.
Went above and beyond so the work got done in a timely manor and we're very satisfied with the results.
Thank you, James & Crew.
Excellent service. Responded quickly to confirm my appointment and the work was completed quickly the same day. We will be using this company for our yearly heating maintenance.
I had a great experience working with James and his team to install our new boiler and water heater. He worked to understand our needs, gave us solid advice, and provided a competitive bid with no extras or upsells (and no BS!). His work was very professionally done, and it was obvious that he took great pride in his work and in providing the most useful components. He also took the time to explain the work, how the equipment worked, and made sure the settings were what we we were looking for. All in all a great experience, and we will be working with him again.

Because we're based in Norwood, just about five miles from Walpole, we can typically reach your home faster than most competitors. For urgent situations like a furnace failure in winter or a broken AC during a heat wave, we prioritize same-day service whenever possible.
Most Walpole homes use forced hot air systems with a gas furnace, though older neighborhoods also have a fair number of boilers and hydronic baseboard systems. We service all types and can help you decide whether to repair your current system or upgrade to something more efficient based on your home's layout and your budget.
Heat pumps have become a strong option for Massachusetts homeowners, especially with available MassSave rebates. Modern cold-climate heat pumps work effectively even during Walpole's coldest months and can reduce your heating costs compared to oil or electric resistance heat. We can assess your home and walk you through the numbers.
We install whole-home air purifiers, HEPA filtration upgrades, and UV germicidal lights that integrate with your existing HVAC system. Many Walpole homeowners, particularly those with allergies or respiratory concerns, find that improved air filtration makes a noticeable difference in daily comfort.
