It compresses low-pressure refrigerant vapor into a high-pressure, high-temperature gas and circulates it through the condenser and evaporator coils, driving the entire refrigeration cycle that removes heat from your home. This unit is matched to the displacement, voltage, and refrigerant specifications your Lennox system was designed for.\u003c\/p\u003e\u003cp\u003eCommon signs of a failing compressor include a system that runs but no longer cools, hard-starting or repeated tripping of the breaker, loud clattering or grinding noises, warm air at the supply registers, and the outdoor unit that hums but will not start. Electrical failures such as a grounded or open winding, or mechanical seizure, all point to compressor replacement.\u003c\/p\u003e\u003cp\u003eInstalling the OEM \u003cstrong\u003e11C29\u003c\/strong\u003e is critical because compressor replacement is one of the most labor-intensive HVAC repairs, and a mismatched aftermarket unit can cause improper oil charge, poor efficiency, and premature failure. The factory compressor arrives with the correct internal oil charge and terminal configuration, ensuring proper capacity, warranty compliance, and long service life for your Lennox equipment.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081137766771,"sku":"LNX-11C29","price":389.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-compressor-11c29","provider":"National HVAC Parts","version":"1.0","type":"link"}
