Rheem HVAC Repair in NYC
AM Profs Inc diagnoses and repairs Rheem furnaces, central air conditioners, and light-commercial rooftop units across New York City. If an EcoNet-connected system is misreporting status, a furnace won't hold a call for heat, or an AC unit is short-cycling, we start from the actual fault.
24/7 urgent repair is available for Rheem furnaces and AC systems, including weekends and holidays.
Covered Equipment
Gas furnaces
Central air conditioners
Commercial rooftop units
EcoNet smart home controls
Heat pumps
Rheem and Ruud share manufacturing and many internal components, which often means faster parts sourcing across both brands.
Quick Answer
What is the most common Rheem repair issue in NYC?
The most common Rheem calls involve furnace ignition faults, AC units that run without cooling effectively, and EcoNet connectivity issues on newer systems. Because Rheem and Ruud share manufacturing facilities and many internal components, parts availability tends to be less of a bottleneck than with more proprietary brands.

Why Rheem Repairs Need Brand-Specific Service
One of the more interesting details in Rheem's history is a 1959 acquisition: Rheem bought the Ruud Manufacturing Company, uniting two of the most historically significant and closely related brands in the American HVAC industry — which is why the two brands' parts are so often interchangeable today.
Richard and Donald Rheem founded the company in 1925 in Emeryville, California, originally manufacturing galvanized steel water tanks before expanding into HVAC. The brand is currently owned by Paloma Industries, a Japanese water heater manufacturer that acquired Rheem in 1988.
What Makes The Brand Different
Shared parts with Ruud speed up repairs
Because Rheem and Ruud share manufacturing facilities and internal components, many OEM repair parts for furnaces and air conditioners are interchangeable between the two brands, which can meaningfully reduce wait times compared to more proprietary equipment.
Rheem's EcoNet platform ties thermostats, furnaces, and outdoor units together for monitoring and control, so a reported fault sometimes traces back to a connectivity issue rather than the equipment itself.
Rheem Systems We Service
Common symptoms, likely causes, what we check first, and when to call for each system type.
Gas Furnace
Common symptoms: Furnace won't ignite, cycles off early, or blows air that isn't warming up.
Likely causes: Ignitor failure, flame sensor fouling, pressure switch fault, or restricted airflow.
What we check first: Ignition sequence, flame sensor signal, pressure switch, and airflow.
What work is done: Ignitor or flame sensor replacement, pressure switch service, and airflow correction.
When to call: As soon as the furnace repeatedly fails to hold a call for heat.
Central Air Conditioner
Common symptoms: AC short-cycles, runs without cooling, or the outdoor unit hums without starting.
Likely causes: Capacitor failure, refrigerant leak, or a failing condenser fan motor.
What we check first: Capacitor readings, refrigerant pressures, and fan motor condition.
What work is done: Capacitor replacement, leak repair and recharge, and fan motor service.
When to call: If the outdoor unit hums without starting or the system won't cool the space.
Commercial Rooftop Unit
Common symptoms: Unit short-cycles or the served space isn't reaching setpoint.
Likely causes: Condenser fan motor failure, control-board fault, or refrigerant leak.
What we check first: Fan motor condition, control-board fault history, and refrigerant charge.
What work is done: Fan motor replacement, board diagnostics, and leak repair and recharge.
When to call: If the unit is short-cycling or not reaching temperature for the served space.
Frequently Asked Questions
Are Rheem and Ruud parts really interchangeable?
Largely, yes. The two brands share manufacturing facilities and many internal components since Rheem's 1959 acquisition of Ruud, which often makes parts sourcing faster than with more proprietary equipment.
What does EcoNet do on a Rheem system?
EcoNet connects thermostats, furnaces, and outdoor units for monitoring and control. A reported fault on the app or thermostat sometimes traces back to a connectivity issue rather than a mechanical problem with the equipment itself.
Why does my Rheem AC hum but not start?
That's a common sign of a failed run or start capacitor, or occasionally a seized condenser fan motor — both are straightforward to diagnose and replace.
Do you service Rheem commercial rooftop units?
Yes, alongside residential furnaces, AC, and heat pumps.
What areas of NYC do you cover for Rheem repair?
We schedule Rheem repair across Manhattan, Brooklyn, Queens, and the Bronx.
