Massachusetts winters don't leave much room for a heating system that isn't working. Stardust HVAC repairs residential and commercial heating systems in Lawrence and throughout the Merrimack Valley, including furnaces, boilers, heat pumps, and ductless systems.
We diagnose the problem, explain what's going on, and give you clear repair options so you can get heat back in your home.
Signs Your Heating System Needs Repair
Call for service if your system won't turn on, blows cold air, short cycles, makes banging or squealing noises, has uneven heat between rooms, or your energy bills have jumped without explanation. A pilot or ignition that won't stay lit, radiators that stay cold, or a thermostat that doesn't seem to control the system are also common reasons for a heating repair call.
Heating Systems We Repair
We work on gas furnaces, hot water and steam boilers, heat pumps, and ductless mini-split systems. Each type has its own common failure points. Furnaces often have ignition, flame sensor, blower, or pressure switch issues. Boilers may have circulator, expansion tank, or control problems. Heat pumps can have defrost or reversing valve issues.
For details, see our pages on furnace services, boiler services, and heat pump services.
When to Treat It as an Emergency
No heat during freezing weather can lead to frozen pipes and unsafe conditions. If you smell gas, leave the home immediately and call your gas utility or 911 from outside before calling for HVAC service. For a heating system that has stopped working, call us at 978-626-3794 — we're available 7:00 AM to midnight every day.

Heating Repair FAQs
Why is my furnace blowing cold air?
Common causes include an ignition or flame sensor problem, a dirty filter causing overheating, a thermostat setting, or a gas supply issue. A technician can diagnose it safely.
What should I check before calling for heating repair?
Check that the thermostat is set to heat, the breaker or service switch is on, and the filter isn't clogged. If it still doesn't work, call for service.
Do you repair boilers and furnaces?
Yes. We repair furnaces, boilers, heat pumps, and ductless heating systems.
