FAQ

Who repairs Simon-Aire PTAC units in Manhattan?

Our technicians provide professional Simon-Aire PTAC repair throughout Manhattan for units installed in apartments, hotels, offices, healthcare facilities, and commercial properties. Because we regularly work with through-the-wall systems, we inspect the complete unit—including airflow, controls, electrical components, heating, cooling, and drainage—before recommending a repair. Contact our team to schedule experienced Simon-Aire PTAC service.

Why is my Simon-Aire PTAC running but not cooling the room?

A Simon-Aire PTAC may run without cooling effectively because of restricted airflow, a dirty coil, a weak fan motor, an inaccurate sensor, a thermostat issue, a compressor fault, or another refrigeration problem. In our experience, similar symptoms often have different causes, so we test airflow, temperatures, controls, and refrigeration performance together rather than replacing parts based on guesswork. Contact our team for professional cooling diagnostics in Manhattan.

Why is my Simon-Aire PTAC blowing air but not producing heat?

The cause depends on whether the unit uses electric resistance heat, a heat pump, or a hydronic heating assembly. A failed heating element, valve, sensor, thermostat, relay, control board, wiring connection, or heat-pump component may prevent proper heating. Our technicians identify the exact Simon-Aire configuration, test the full heating circuit, and recommend the appropriate repair.

What does the error code on my Simon-Aire PTAC mean?

An error code points to the system where the unit detected an abnormal condition, but it does not always identify the exact failed component. The meaning can also vary by model and control package. Send our team the code together with a photo of the model and serial label, or schedule a visit so we can test the related sensors, controls, electrical circuits, and operating conditions.

Can a Simon-Aire PTAC be reset, or does it need repair?

A reset may clear a temporary electronic fault, but it will not correct a failed motor, sensor, heating component, compressor, control board, or wiring problem. If the code returns, the unit shuts down again, or heating and cooling do not resume normally, the underlying fault should be diagnosed. Our technicians can reset the controls safely, test the system, and repair the actual cause.

Can I use a wall thermostat with a Simon-Aire PTAC?

Some Simon-Aire models support wall thermostats or remote control options, but compatibility depends on the model, voltage, control board, wiring configuration, and thermostat type. Our experience shows that incorrect thermostat wiring can create intermittent operation or damage the controls. Contact our team with the model number, and we can verify compatibility and arrange professional thermostat installation or repair.

Can Simon-Aire replace an old McQuay, Ice Air, Islandaire, or Applied Comfort PTAC?

Simon-Aire manufactures exact-replacement PTAC chassis for many legacy systems, including selected McQuay, Ice Air, Islandaire, Applied Comfort, ClimateMaster, Trane, and other configurations. Compatibility still depends on sleeve dimensions, voltage, capacity, airflow direction, heating type, and existing controls. Our technicians can inspect the old unit and installation and help determine whether a Simon-Aire replacement will fit correctly.

Is it better to repair or replace an older Simon-Aire PTAC?

Repair may be practical when the cabinet, coils, compressor, fan assembly, and main electrical systems remain in good condition and compatible parts are available. Replacement may be the better option when the unit has repeated failures, severe corrosion, major refrigeration damage, or obsolete controls. Contact our team for an inspection, and we will evaluate the complete system and explain the most sensible long-term option.

Are replacement parts available for Simon-Aire PTAC units?

Parts and accessories are available for many Simon-Aire models, including hydronic heat assemblies, wall sleeves, louvers, room enclosures, touch pads, remote controls, motors, sensors, and other components. Availability depends on the exact model, series, voltage, and age. Send our team a clear photo of the identification label so we can help identify compatible parts and arrange professional repair.

Where can I find the model and serial number on a Simon-Aire PTAC?

The model and serial number are usually printed on an identification label attached to the chassis, often behind the front cover or near the electrical compartment. Because Simon-Aire manufactures many exact-replacement configurations, this information is essential for finding the correct manual and parts. Send our team a photo of the label and control panel so we can prepare more accurately for the service visit.

Why is my Simon-Aire PTAC leaking water into the room?

Water leakage can result from a blocked condensate path, a dirty evaporator coil, a cracked drain pan, incorrect chassis pitch, a frozen coil, or excessive moisture. Based on our experience with Manhattan PTAC installations, the visible leak may travel along the cabinet before appearing indoors. We inspect the drain system, coil, pan, airflow, and installation angle to locate the source and prevent damage to walls and flooring.

Why is my Simon-Aire PTAC making a loud rattling, grinding, or buzzing noise?

Rattling may come from loose panels, a blower wheel, motor mounts, or debris, while grinding can indicate bearing or motor wear and buzzing may point to a relay, transformer, compressor, or electrical connection. Our familiarity with compact PTAC layouts helps us separate normal vibration from a developing mechanical or electrical failure. We operate the unit, trace the sound, and identify the component that needs adjustment or replacement.

Why does my Simon-Aire PTAC keep turning on and off?

Frequent cycling may be caused by restricted airflow, an inaccurate room sensor, thermostat problems, overheating, control-board faults, or a safety device opening the circuit. In our experience, short cycling often involves more than one condition, such as a dirty coil combined with incorrect temperature readings. We test the full operating cycle, airflow, controls, electrical load, and temperature changes before recommending a repair.

Why is the fan on my Simon-Aire PTAC not working?

A failed fan motor, capacitor, control board, relay, wiring connection, damaged blower wheel, or obstruction can stop the fan. Since poor airflow can lead to overheating or coil freezing, the unit should not be operated for long in this condition. Our technicians test the motor circuit, control signal, blower assembly, and related electrical components to identify the correct repair.

Why does my Simon-Aire PTAC smell musty when it runs?

A musty odor usually develops when moisture and dust collect on the evaporator coil, filter, drain pan, insulation, or internal cabinet surfaces. In humid or high-occupancy Manhattan buildings, replacing the filter alone may not solve the problem if condensate is draining poorly. We inspect the moisture source, drainage, coil condition, and airflow and clean accessible components to reduce the chance of the odor returning.

Why is my Simon-Aire PTAC freezing up?

Ice may form because of restricted airflow, a dirty filter or coil, a weak fan, an inaccurate sensor, or a refrigeration fault. Our experience shows that assuming every frozen coil needs refrigerant can lead to an incorrect repair. We first inspect airflow, fan performance, temperature readings, controls, and coil condition, then test the refrigeration system if necessary. Turn the unit off until the ice melts and the cause is identified.

How often should a Simon-Aire PTAC be serviced?

Service frequency depends on operating hours, occupancy, indoor air quality, and building type. Units in hotels, healthcare facilities, rental buildings, and busy offices usually need more frequent attention than lightly used residential systems. Based on the PTAC systems we service in Manhattan, routine inspection of filters, coils, drains, fans, controls, and electrical connections can reduce unexpected breakdowns and maintain steadier heating and cooling.

Can you service multiple Simon-Aire PTAC units in one building?

Yes. We service individual Simon-Aire units and groups of PTAC systems in apartment buildings, hotels, offices, healthcare facilities, and other properties. Our experience with multi-unit projects allows us to coordinate access, inspect units efficiently, document their condition, identify recurring faults, and prioritize urgent repairs. Property managers can contact our team to arrange scheduled maintenance or building-wide Simon-Aire PTAC service.

Why is my Simon-Aire PTAC using more electricity than usual?

Higher energy use can result from dirty coils, restricted airflow, a weak fan motor, inaccurate thermostat readings, damaged heating components, refrigeration problems, or long operating cycles. In our experience, several smaller efficiency issues often combine to increase consumption. We evaluate airflow, temperatures, controls, electrical performance, and component condition to determine whether cleaning, repair, or replacement is the most practical solution.

What information should I provide when scheduling Simon-Aire PTAC repair?

Provide the model and serial number, voltage, displayed error code, and a clear description of the symptoms. Photos of the identification label, control panel, wall sleeve, and any visible leakage or damage are also helpful. Because Simon-Aire offers many exact-replacement and heating configurations, this information allows our experienced technicians to identify the system more accurately and prepare for the service visit.
