David Cueto was very informative and he explained a lot to me.....
5 Stars to their Tech, David C., the company owner that called me back to answer my questions and concerns, and the new receptionist that helped schedule my service. I noticed some water in my attic air-handler emergency drain pan and called Just-N-Time and they came out the next day. Turns out my drainage line was…
I think this was maybe the result of the tech assigned to us. The tech did not do a thorough job of inspecting our ACs for issues. He just noticed refrigerant leaked and he refilled it. He did mention he didn’t have a tool he needed to do the rest of the inspection and that would be another appointment. Definitely…
Thanks again Jus-N-Time for taking care of My Summrr Time tune up. I'm always happy with my many years of service. Sincerely Joe June 26th 2026... Another year keeping my system running perfectly. Thanks Just-n-Time
great service
Fair priced, honest quality work with no sales pressure and great communication and professionalism
I called several places and finally found a reputable shop willing to give me a preliminary quote AND come out within 30 minutes. LJ had a great attitude and educated me in the process. He was able to listen to the customer and was able to effectively do his job within 10-15 mins of being on-site. Payment was…
Had a difficult situation where the original AC contractor was thrown off the work......... Just-N-Time stepped in and helped me get up and running they inspected the system replaced a defective coil and found an underground coolant leak ......... all is good and appreciate the help from everyone involved !
Always on time. Through and explains. Very considerate , polite...doesn't mansplain
It seemed thorough and quick. Thanks to David
Great job
Very good service, knowledgeable and professional. The technician arrived on time and the price for our two units was reasonable. We highly recommend them.
Excellent service
Miguel Mendoza with Just-N-Time AC and Heating. Miguel was very professional and courteous!! I will definitely recommend and use some in the future.
The tech that came to our house, his last name was Cuesto (forgot his first name): positive, helpful, efficient and provided a truly pleasant experience, as well as useful, friendly and obliging service. This company deserves its high reviews. Recommended. Good job, Cuesto!
Very good work / reliable / make sure it's done right
I’ve been using JIT for years and Justin does quality work and listens to his customers to get the best outcomes.
David Cueto, was great he answered all my questions and was very professional
Just-N-Time was very professional, efficient and explained everything he needed to do without hesitation. He isolated the issue and the unit is working better than it ever was.
The Technician is very knowledgeable and cordial. He is offered explanations for the just done
David was thorough and provided video of what was happening in our attic with our HVAC system. He also provided some options for helping with mildew build for our house built in 1947.
LJ and his side kick did an excellent job.
Spring maintenance done. Quick and efficient. Very happy with their work. Provided right level of detail on current state of our systems and items that will need to be addressed in the near future.
Excellent & professional service. Thank you
I contacted this company as a referral from a friend. Our Ac system had been down since Saturday. They came out in less than 2 hours after I called. They repaired my system promptly. Justin explained the process thoroughly. So: My system is very old and needs to be replaced in time. It’s is functioning as it should…
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…
So happy that I found this company!
Laine was on time, friendly, knowledgeable and informative. Good service call.
Incredible service as usual, highly recommend this company!!!
Our technician was Laine and was very professional, arrived on time and explained all work needed before working on our unit. Highly recommend Just-N-Time air Conditioning!
My restaurant's dining room compressor & my blower fan for my karaoke room abruptly died. I was having issues with 2 other companies with crazy lead times (1-2 weeks) for compressors and blow fans..... Justin was super professional and ridiculously quick with replacing both the same day he came to do a diagnostic!…
Techs were great. They were nice. And very pleasant people.
I have been using Just-N-Time for almost 2 years now through their maintenance program and am consistently blown away by their timeliness, professionalism, quality of work, and value. They are always honest and helpful. What a great company.
LJ was on time, professional and knowledgeable. Great combo!
Justin replaces an old a/c for us, installed surge protectors on some other units, and fixed an issue with one. He is friendly and professional. I highly recommend his business! We have been using this company for regular maintenance checks. They are very responsive when we have an issue.
Justin, LJ, and Scarlett were all so helpful with the entire process. I don’t write reviews often mostly because of time, but these folks deserve it. If I could give them 10 stars, I would. We had our AC repaired in a very timely manner and what seemed to have been at a fair cost. I called around multiple places to…
They listened to what I was wanting and needed but also recommended what would work best are my size house. I was thinking of purchasing a three-and-a-half ton or a 4-ton unit but a 3 ton unit work best.
We use Just-N-Time AC +Heating for our company and personal use. They are very reliable and come out right away if we have an issue. It's hard to find honest companies no days so I am glad I finally found one.
After MANY reviews of an HVAC company, I honestly believe that JUST-N-TIME HVAC is the BEST you can get! I am so beyond impressed with the service/maintenance that we received tonight! Any of my Texas peeps really need to hire this company! $180. for annual maintenance which includes a 21 point inspection each time!…
Prompt response, professional and quality workmanship.
