🛠️ HVAC Depot Pro Tip
The 10M23 / 103881-01 is a 3/8-inch liquid line service valve. Do not confuse it with the larger suction-line service valve that may be installed on the same condenser or heat pump.
Before ordering, verify:
- Cat # 10M23
- Part # 103881-01
- 3/8-inch line size
- Liquid line application
- Existing valve configuration
- Connection type
- Outdoor unit model number
- Equipment serial number
- Refrigerant requirements
Service valves may look very similar externally, so always match the OEM part number and equipment model rather than relying only on line size.
Equipment / Model Compatibility
The Lennox 10M23 / 103881-01 is used with select Lennox outdoor HVAC equipment, including compatible:
- Lennox air conditioners
- Lennox heat pumps
- Outdoor condensing units
- Central air conditioning systems
- Select 13ACX Series equipment
- Select XC13 Series equipment
- Other Lennox systems specifically calling for 103881-01
Always verify the complete equipment model and serial number before ordering.

Michel & Siso are very knowledgeable and explain everything to where I could understand! Amazing experience! Thank you will always come here for any AC needs. Trustworthy and excellent customer service.

Happy Shouts From Our Thrilled Customers
William Bartlett
Cecil really saved me with troubleshooting tips over the phone. Thought I was going to have to replace the blower motor and ended up only needing a motor run capcitor. Thank you and God bless!
Riley Connolly
Cecil and Fidel were absolutely amazing and so helpful. We were happy they were open on Sunday, but was impressed with their knowledge and willingness to make sure we had everything we needed. If you need parts or service or install, I would recommend.
Cole Meger
Our AC went out during the hottest stretch of summer, and with a one-year-old at home, we were desperate for a quick fix. These guys came through big time — not only did they source the part faster than anyone else in the area, they also walked me through DIY troubleshooting while I waited. Trustworthy, knowledgeable, and run by a solid local family. As someone who owns rental properties nearby, I’ll be sourcing all my HVAC parts from them moving forward. Highly recommend!
Carl T. Droste
Had a power outage last night and during the 100 degree heat today noticed that the AC was not blowing any cold air. Pulled the capacitors to have them checked and also took video of the relay making noise even with the breaker was off. The proprietor and her staff were very friendly and helpful. She had the video analyzed and confirmed something was wrong. She checked one of the capacitors was a little low. Capacitor replacement is the biggest ticket item for HVAC repair. It is hundreds of dollars with the a capacitor only about $20.
Fuzzy Wuzzy
Cecil and his family have been a life saver. I walked in with very little knowledge on parts let alone how to repair my unit. All I had was my brother in FL who knows more than I do and Cecil at HVAC Depot. With 2 young kids at home I couldn't afford to wait for a HVAC tech. Cecil walked me through what I needed to know, even after hours when the shop closed. I successfully repaired the fan motor and replaced the capacitor. Thank you HVAC team for being totally awesome. Prices were amazing and I'm forever going to support this small family business. You and your family are what Texas is all about!!!
Linda Robinson
I called HVAC Depot and was absolutely blown away by the fast, courteous and exceptional service. They were very knowledgeable about explaining what they were doing and what had happened to the ac system. If you ever need a HVAC team they are best and they won’t hesitate by coming out and they won’t leave until you are happy with the service. Thank you so much for your excellent service. Kudos to you Michelle for your amazing customer service.
Paul Hamer
My AC went out in our home on Friday night. I went out and got the capacitor details and took them here first thing Saturday morning. Lady at the counter was friendly and had the capacitor I needed! When I got home, I installed the capacitor and AC is all good!!
Jeff Ledesma
Awesome support and had everything I needed for an older unit! Then helped me out with the DIY!! Air conditioning back up and running at 100%!!
Thanks for everything
