Keep your HS29-036-2 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The HS29-036-2 is a three-ton R-22 residential outdoor condensing unit. The unit uses R-22 refrigerant requiring EPA 608 certified technicians for any refrigerant circuit service. The HS29-036-2 and HS29-036-2P are successive production revisions of the same three-ton HS29 platform. Most service components including the run capacitor and contactor are shared between both revisions. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Lennox OEM parts for the HS29-036-2 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

HS29-036-2: Three-Ton R-22 Outdoor Condensing Unit Service
Annual capacitance testing of the dual run capacitor before the cooling season is the most cost-effective preventive maintenance step for the HS29-036-2. Match all microfarad values from the installed capacitor label before ordering a replacement. The central air conditioner repair help section covers capacitor testing and contactor diagnosis for this platform.
Most Replaced Parts on the HS29-036-2
Dual Run Capacitor for the HS29-036-2
The dual run capacitor provides starting and running torque for both the compressor and outdoor fan motor in a single can. A capacitor reading more than 10% below its rated microfarad value causes the compressor to hard-start, accumulating heat in the motor windings. Match all three microfarad values from the installed capacitor label before ordering.
HS29-036-2 Contactor
The contactor closes the 240-volt compressor power circuit at every cooling cycle start. Pitted or burned contact surfaces generate heat that transfers to the compressor motor terminals. Replace a contactor with visibly eroded contacts before compressor winding damage occurs.
Outdoor Fan Motor for the HS29-036-2
The outdoor fan motor pulls air through the condenser coil. Test the run capacitor before ordering a replacement motor, as a failed capacitor produces identical slow-start symptoms at a fraction of the motor replacement cost.
High-Pressure Switch for the HS29-036-2
A high-pressure switch that trips repeatedly under normal ambient conditions points to a blocked condenser coil, failed fan motor, or refrigerant overcharge rather than a failed switch diaphragm.

HS29-036-2 Parts FAQ
What is the HS29-036-2 and what ton size is it?
The HS29-036-2 is a three-ton R-22 residential outdoor condensing unit from Lennox’s HS29 series. The unit uses R-22 refrigerant requiring EPA 608 certified technicians for any refrigerant circuit service.
Why does my HS29-036-2 hum but not start?
A unit that hums but does not start has most commonly failed at the dual run capacitor, which cannot provide adequate starting torque to the compressor or fan motor. Test the capacitor with a digital capacitance meter before testing any other component.
What is the difference between the Lennox HS29-036-2 and the HS29-030-1P?
The HS29-036-2 is a three-ton unit while the HS29-030-1P is a two-and-a-half-ton unit in the same Lennox HS29 R-22 product line. The run capacitor carries different compressor-section microfarad ratings between the two tonnages. Never substitute capacitor specifications between the 036 and 030 configurations.
How often should I test the capacitor on the HS29-036-2?
Test the capacitor annually before the cooling season. A reading more than 10% below the rated microfarad value indicates a weakening capacitor that should be replaced before it fails under peak summer load.
