Heater Repair in Long Island

A Family-Owned Heating Company in Business Since 1988

At AWS Plumbing, Heating & Cooling, we provide heating repair for residential and commercial properties across Long Island. Our technicians diagnose problems affecting furnaces, heat pumps, boilers, radiant heating systems, ductless equipment, and other gas, oil, and electric heating systems.

A heating symptom doesn’t always identify the failed component. No heat, repeated cycling, unusual sounds, or cold rooms may involve the thermostat and controls, ignition, airflow, circulation, electrical supply, or another part of the system. We inspect the equipment and isolate the problem before recommending a repair or replacement part.

If your heating system isn’t working properly, call us at (516) 217-2196 or contact us online to schedule an appointment.

Heating Equipment We Repair Across Long Island

Heating repair can involve more than a single appliance, particularly when boilers, radiators, zones, controls, and plumbing-related components operate together. We work with equipment from leading manufacturers, including Carrier and Bosch, and service both newer systems and mechanical equipment built to earlier standards.

Boilers & Hydronic Heating
Boiler repair may require testing the burner, ignition, water pressure, circulators, zone valves, controls, piping, or venting. For radiant and other hydronic heating systems, we also investigate cold zones, trapped air, circulation problems, pressure changes, and uneven heat at radiators or baseboard loops.

Furnaces
Our furnace repair process can include checks of the ignition, burners, flame sensor, blower components, thermostat, airflow, electrical controls, venting, and safety switches. We service gas, oil, and electric heating systems in homes and commercial properties.

Heat Pumps & Ductless Systems
Heat pump repair and ductless heating service may involve airflow, coils, electrical controls, thermostat settings, refrigerant performance, or operating-mode changes. We test the equipment to determine why it won’t start, won’t stay running, or isn’t producing sufficient heat.

Older Heating Systems
We service older and historic properties whose mechanical systems may operate according to earlier standards. When the equipment requires more than a standard repair, we also provide code violation removal services and modernization upgrades.

Vetted Heating Technicians You Can Trust

Inviting a technician into your home or business requires trust. At AWS Plumbing, Heating & Cooling, we fully vet, background check, and drug test technicians before sending them to a customer’s property.

We are fully licensed and insured, and we’re an EPA Certified Lead-Safe contractor. Our qualifications also include an A+ rating from the Better Business Bureau, Carrier Factory Authorized Dealer status, recognition as a Bosch Home Comfort Pro, and designation as a Home Depot Authorized Independent Provider. We received the Carrier President’s Award in both 2023 and 2024.

Warning Signs Your Heating System Needs Repair

Early warning signs can point to a developing problem before the system breaks down.

Your system may need professional attention if you notice:

• Ineffective or repeated heating cycles
• Indoor Air Quality Issues
• Cold rooms or heating zones
• Unusually large energy bills
• Unusual equipment sounds
• A boiler leak or loss of pressure
• A system that won’t start or stay running

If you suspect a gas leak, see smoke or fire, hear a carbon monoxide alarm, or observe an unsafe electrical condition, stop troubleshooting and take immediate safety action. Don’t restart or keep operating equipment that may be unsafe.
