The TXV meters refrigerant flow into the evaporator coil, maintaining proper superheat and protecting the compressor from liquid slugging. This kit is intended for air conditioning and heat pump applications and is installed by licensed HVAC technicians during new system commissioning or refrigerant-side service. The 920669A delivers an OEM-compatible replacement that restores proper metering device function in affected air handler units.\u003c\/p\u003e\n\u003cp\u003eThis TXV kit is rated for R-410A refrigerant systems at 2.5-ton capacity and is used in air handler installations for both air conditioning and heat pump configurations. It is suited for residential applications where the evaporator metering device has failed, is restricting flow, or must be upgraded as part of a system efficiency or refrigerant retrofit. Compatible model information from the manufacturer identifies specific GB5BM-series air handler units as the intended application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated for R-410A refrigerant — no cross-refrigerant substitution required\u003c\/li\u003e\n  \u003cli\u003e2.5-ton capacity matches common residential split-system sizing\u003c\/li\u003e\n  \u003cli\u003eDual AC and heat pump (AC\/HP) compatibility within the intended model range\u003c\/li\u003e\n  \u003cli\u003eOEM-style kit format includes components needed for a complete metering device replacement\u003c\/li\u003e\n  \u003cli\u003eDesigned for GB5BM-series air handlers per manufacturer specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on GB5BM-series air handler units, specifically part numbers 04304GD\/GB5BM-X30K-A and 904306GD\/GB5BM-X30K-B, per manufacturer specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by an EPA Section 608 certified HVAC technician. The refrigerant system must be recovered and the unit de-energized before replacing the TXV. After installation, the system must be evacuated to the required micron level before recharging with R-410A. Verify proper superheat and subcooling readings at startup to confirm correct valve operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Type\u003c\/strong\u003e: R-410A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 2.5 Ton\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Conditioning and Heat Pump (AC\/HP)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Air Handler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Model Series\u003c\/strong\u003e: GB5BM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Part Numbers\u003c\/strong\u003e: 04304GD\/GB5BM-X30K-A, 904306GD\/GB5BM-X30K-B\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WESTINGHOUSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 920669A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284095172914,"sku":"920669A","price":170.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278182.png?v=1781068452","url":"https:\/\/voomisupply.com\/products\/westinghouse-920669a-txv-kit-r-410a-2-5-ton-air-handler","provider":"Voomi Supply","version":"1.0","type":"link"}
