What Our Clients Are Saying


Kyle M.


Justin and his team did a great job repairing our air conditioning units. We also had some dampers in our zoning system that weren’t opening and closing properly and they were able to fix those for us as well.



Sam J.


10/10 experience. Just-n-time came out to my Airbnb in the middle of the night, diagnosed and repaired the issue on the spot. Shoutout LJ for the professional & fast repair. Would recommend.



Olivia M.


Our ac went out last night (on a Friday) and I needed someone asap. Justin tried to help me override the thermostat to get some air until repairs could be made. Unfortunately, it didn’t work but they were able to show up first thing in the morning. They fixed my ac and gave me some useful info. I’m totally happy with their great customer service, punctuality, and their affordable prices. I will definitely recommend them to family and friends. You guys are awesome sauce.



Michael C.


Haris, Justin, and the entire crew were professional, prompt, and thorough. AC decided to break down overnight, and even though it was a stressful time, Just-N-Time made it an easy process. We decided to replace our entire AC system and duct work, and everything is now running smoothly. Thanks Haris for answering all of my questions and for your professionalism. Thanks Justin for overseeing the install and making sure everything was done correctly. Highly recommend them!



Steve A.


Had a blower fan go out and other companies wanting to charge for a whole new furnace, but not these guys! An HONEST approach to home repairs is such a refreshing thing to encounter these days. It’s rare! And Haris could not have been more polite, professional, and attentive. Great at what he does! Keep up the great work Just-N-Time! You guys rock! And you will be the people I call next time too.

April 11, 2022 Our 3rd year with Just-In-Time A/C and Heating, as previously stated, the relationship started from Next Door and we have not been disappointed- Harris has been the service tech for two years, he very knowledgeable and a great guy- So our Spring checkup is done—If you’re looking for dependable A/C Service — I strongly recommend Just-In-Time A/C and Heating— Thank you, Justin, Scarlett & Harris!!



Justin R.


They sent Haris out for our cleaning/maintenance of our system. He had all the answers to my questions, he was very friendly, and he stayed out of our way in a busy shop environment. I will be depending on Just-N-Time for all of our HVAC needs going forward.



Eddie N.


Wow. AC went out on hottest day of the month so far. Was supposed to come between 3-8 which usually means 9 He called and said could come early. Yippee. Got here at 9. Examined system and saw issues. Showed then to me and I kinda already knew problems since thus one has been nothing but problems every year. Wrong size installed. Wrong kind etc. ( I have a three story townhouse with three zones ). Told/ showed me options. I’m staying here at least 5 mot3 years and tired of the problems! New system that now has aluminum coil instead of copper that rusts ! Plus it’s the right kind! He and his great crew had it up and running in 6 hours ( they had to remove fence too in install outside unit ). Plus hauling it up four flights of stairs! Super nice guys. I even fed them. Lol. I couldn’t be happier! Highly highly recommend him and his team! GREAT JOB ! Plus warranty! Now I’ll be cool all summer and warm all winter! One happy camper ! Thanks Justin and team.



Mabel Romero


I can not say enough goods thing about this crew. It’s the middle of summer and our house was 98 degrees. We reached out last minute because our a/c broke and they were able to squeeze us in. This is what great customer service is all about. The rep kept in Contact with me through the day and when they finally arrived they fixed the issue within minutes. They didn’t leave until my home Cooled down. Thank you so much. Would highly recommend!!!



Cippy Estrada


Was pleased with the professionalism and quick response. Just the fact that he went into depth of what issue was. I recommend his service and work.



Anjulee Hinojosa


Justin was easy to reach and very responsive. He came out when we initially had our house inspected and quickly determined the issue and provided an estimated cost. When we closed, we had arranged for him to come out on a different day. When asked if he could complete the repair sooner, he was flexible and did so. Our home was cool in no time! I would highly recommend Just-N-Time to anyone.



Alvonda Michelle Howard


Scrolling through Nextdoor looking for a reliable A/C business – we noticed Just-In-Time A/C and Heating received several good reviews. We called Justin set-up an appointment for the next day. Justin analysis was a leak in the coil 🙁 — there was good news per Justin – a manufacturer warranty!!! He schedule the following day for replacing the coil, servicing the unit & replacing air filters etc. For us what was most important, a very professional job, Justin registering all our hardware so we may receive the entitle warranties & taking time to give a Honeywell thermostat best practice session. It was a wonderful experience and moving forward, Justin with Just-In-Time is our guy for all our A/C & Heating needs. Thank you so much Justin!!!
