Whether you are dealing with a mid-summer cooling outage or a mid-winter deep freeze, James A. Dalelis Plumbing & HVAC is here for you. We provide reliable, after-hours emergency HVAC repair services throughout Norwood and the surrounding areas.

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.
An HVAC issue becomes an emergency when your heating or cooling system stops working in extreme temperatures or when the problem poses a risk to your home or safety. Common HVAC emergencies include:
If your comfort, safety, or equipment is at risk, treat it as an HVAC emergency.
Call right away if your home has lost heating or cooling in unsafe temperatures or if the system is showing signs of electrical issues, unusual noises, or complete failure. The sooner we diagnose the problem, the faster we can prevent equipment damage and restore comfort.
Dalelis offers fast-response emergency HVAC service. Whether the issue happens at night, early morning, or over the weekend, our team works hard to get a technician out as quickly as possible to stabilize the situation and get your system running again.
It’s best to turn it off. Running a malfunctioning furnace, boiler, AC, or heat pump can cause further damage or create safety risks. Shut the system off and call us so we can diagnose the issue safely.
If the system is not heating or cooling, turn it off to prevent damage. Check that your thermostat has power, confirm filters aren’t severely clogged, and make sure no breakers are tripped. If you smell burning or hear electrical noises, leave the system off and call us immediately.
