We had Miguel Mendoza come out on a Saturday at 8 PM. Miguel came in super clutch and identified and fix the issue with our A/C unit. Miguel was professional and knowledgeable enough to explain everything in terms that we were able to understand, and he showed a high level of professionalism all around.



Cami McLendon


Miguel Mendoza Was awesome. He informed us on some issues that need to be fixed and what the purpose of the part/repair is. Thank you! Will use your company again 🙂



George Soto


I came home from being out of town to no “AC” at my home. I was worried as it was a Sunday. I contacted LJ from Just-N-Time and he was responsive and came out the same day. My family was grateful that we can get superior service even on a Sunday! Thanks LJ!



Adam Coulon


Quick to come out even though I just needed maintenance. Miguel Mendoza was great. Really laid back and explained the condition of my system. Price was very reasonable.

Miguel arrived 30 mins before appointment time. So glad to see his van, on a very warm day. He was able to diagnose and solve a wiring issue quickly. We were cooling within an hr.
Highly recommend Just-n-time.



Carmen Duron

Gan Libisono


We had Miguel coming in to service our AC and couldn’t be happier with his professionalism and his honesty. Another AC company had checked our AC and declared that we needed to spend $20K to replace our unit. Wanting to have a second opinion, we called Just N Time. When Miguel came, I already had a sense of how professional he is. He checked our AC and we ended spending a few hundred dollars based on his suggestion. Miguel explained what he did and gave honest review of our unit. He was not trying to sell us anything but when asked, suggested what plan that will be good for us. Because of him, we plan to stick to Just N Time for our AC/heating unit. Thanks Miguel!
