High CFM capabilities suitable for large commercial spaces.
The unit is designed to handle electric heat kits, allowing for customizable auxiliary heating. Technical Specifications (RHQA 1220T)
When connecting the RHQA 1220T to a standard heat pump system, the typical terminal designations include: Rheem RHQA-1005BHS Furnace Q&A - JustAnswer
: Nominal airflow capacity (typically represents 1,200 CFM, designed for 3-ton cooling systems). 20 : Heating configuration or sequential design revision. rheem model no rhqa 1220t pdf
: These units are designed for horizontal or vertical airflow and are commonly used in residential and multifamily settings.
If your RHQA 1220T is 15-20 years old and has a major failure (such as a leaked evaporator coil, failed blower motor, or compressor burnout), replacement is often the most economical path. A modern air handler will be significantly more energy-efficient, quieter, and will come with a full manufacturer's warranty and readily available manuals.
An older blower motor can start to fail. Listen for high-pitched squealing (a sign of worn bearings) or grinding sounds. These noises mean the motor is working too hard and may need replacement.
(These are typical RHQE/RHQA-series characteristics; confirm exact numbers in the official manual for your precise SKU.) If you need the actual (installation, specs, or
: Third-party document libraries carry specific technical specification sheets for older residential lines.
Unfortunately, I couldn't find a publicly available PDF document that contains all the information mentioned above. However, you can contact Rheem or an authorized distributor to request a PDF copy of the product data sheet, installation manual, or service manual.
| | Likely Cause | Quick Diagnostic Step | | :--- | :--- | :--- | | System not cooling, outdoor unit not running | Thermostat or low-voltage wiring issue. | Check the thermostat display. Set the fan to "ON" to see if the air handler runs without the AC. If not, the thermostat may be faulty. | | System not cooling, outdoor unit runs | Low refrigerant, dirty coil, or dirty filter. | Check the air filter. If it's clean, you likely need a professional to inspect the refrigerant levels. | | Indoor blower runs constantly | Thermostat set to "ON," shorted wiring, or a stuck fan relay on the control board. | Set the thermostat to "AUTO" and see if it still runs. If it does, you may need a new control board. | | Water leaking from the air handler | Clogged drip pan drain line. | Find the drain line (a PVC pipe) and clean it out with a wet/dry vacuum or a brush. | | Air handler is very noisy/vibrating | Loose blower wheel or failing blower motor. | Unlikely to be a DIY fix. Call an HVAC technician to inspect the blower assembly. |

Finding the official PDF for a discontinued product like the RHQA 1220T requires persistence. Here are the best strategies:
First, the PDF ensures . The RHQA series often supports add-on cooling or electric heat strips. The manual provides the intricate wiring diagrams necessary to integrate these electric heat kits safely. Miswiring an air handler can result in catastrophic failure or fire hazards; the PDF schematic is the definitive safeguard against such errors.
Replace the filter. Inspect the evaporator coil and clean with a no-rinse foaming agent. Clogged condensate drain line
The Rheem RHQA 1220T is a 20-ton commercial air-cooled condenser unit, part of Rheem's commercial HVAC product line. It's designed to provide efficient and reliable cooling for large commercial spaces.
: Denotes the factory-installed auxiliary electric heat kit capacity. A "20" signifies 20 kW of electric heat capacity , designed to act as supplemental or emergency heat when outdoor temperatures drop below the heat pump's threshold.
