They are always quick to respond to a situation, find cost-effective solutions, and always are honest! They take the time to explain the issue to us in a way that makes sense!

I looked on yelp and found this company. I read the reviews and Paul messaged me back quickly and let me know he could send over a technician today. I was thrilled, it's been a miserable couple days with no ac! Alex came to fix my ac unit, which is located on the roof. He was very professional and had shoe coverings upon entering my home. This company is reliable and efficient. I am so thankful that Alex was able to fix my ac. I will call this company again when my unit needs maintenance. read less

Jesus came out to discuss the project and provide pricing. He was very professional, knowledgeable, and friendly (unlike the aggressive Nexgen salesperson). The installation team of Kevin and Irvin were great. These guys show up with a smile and are very thorough and clean with their work. If you're reading this I'm sorry you're having hvac issues as this can be very stressful especially in the summer or if you have kids/pets. I'd recommend checking out Jmartin for your hvac needs and avoiding nexgen. read less

Our sales rep (Alex) was very friendly and easy to work with. We received multiple quotes for central air and the pricing from J Martin was the most competitive overall. The install crew were great. Got to our house on time and knocked it out very quickly. Temps are going up (its 96 today) and they only had us down (no AC) for a really brief period. J Martin installed our whole house fan back in 2019 and I had the same positive experience. Very happy overall with customer service. I definitely would work with them again. read less

When I called to schedule a consultation, I was very pleased to hear that they were able to get a technician to review my house the next day. I would have thought during the summer they would be super busy or fully booked. Jesus came out to give a great quote and he also inspected our AC unit as a courtesy. He was very responsive and professional. He was also able to squeeze installation on the only weekday I have off!!! Rather than wait till the end of summer. Installation was super quick and the technician was very informative in showing me how the system works. If you every need your AC checked or if you ever consider adding a whole house fan to your home, don't hesitate to go with J Martin. Very satisfied with the service and professionalism.

My husband called and asked a lot of questions and they were very professional, pleasant, and helpful. After making our decision, we were able to schedule an appointment for inspection and installation for that same week. The two man team that did the installation were prompt, super polite and professional. They protected my hard wood floors, left no mess at all, and were done in less time than anticipated. They were also excellent at explaining the system and the controls to me. The system itself is easy to use and works really well. Hopefully we will see a difference on our electric bill now that we are using the whole house fan at night instead of air conditioning. read less

Caleb was super helpful walking us through the entire process, and we were thankful to take advantage of the no-interest financing the company offers. When it came time for installation, Santiago and Carlos had to be the two nicest, most conscientious people we've ever had do something for us.

I will never use another A/C company only J. Martin. I have never been more impressed by any service company. I have already recommended them to my friends and family.

This unit is 20 years old and now looks new. Anyway hope this post helps anybody trying to decide. You wont go wrong with this company and will want to post your own review afterwards.

I trusted other reviewers and can confidently say the reviews are real! I sent a request for service on Yelp on a Wednesday around 2pm and was on the schedule for the next day (Thursday) between 4-6pm. I was given a call around 5:30pm Thursday by Alex stating he was on his way. Once he arrived he noticed his ladder was a bit short for being able to reach my roof however he tried several other options before giving up and requiring me to schedule another appointment (which I greatly appreciated as I would not have been able to do so until next Wednesday). After Alex got on the roof he was able to notice two different issues causing my problem and had the tools and parts on his truck to repair both. This I also really liked as he didn't need to leave or schedule additional dates to repair. When he left before 8:00pm everything was working properly and I'm very happy! I even signed up for the yearly maintenance program they have as I was so happy with the service. Would definitely recommend. Timely, affordable, and professional. read less It is such a great feeling knowing that there are still honest, hard-working companies out there with professionalism and respect... read moreIt is such a great feeling knowing that there are still honest, hard-working companies out there with professionalism and respect in their core values. I was appreciative of Caleb's responsiveness and speedy service fixing our AC unit. He knew that we needed expedited service due to a home inspection and was able to accommodate our schedule. Upon evaluation, he was completely transparent with the data that he was reading from our unit and did not try to sell us on anything that we did not need. I appreciated his clear communication and respect for our yard and home as he navigated our property to identify the issue.

He recommended a whole new system. He had availability the next day and the following week. However since we wanted to do our due diligence and shop around we waited another 2 weeks to get more quotes.

They were very knowledgeable about the benefits and downsides of this type of fan, and were able to guide me through choosing the right one. I was quoted a price, and that never changed throughout the process. I appreciate knowing exactly what I'm paying ahead of time. The installers (Gerry and Luis, I think - I'm writing this review a little late) spent a lot of time in the attic finding as many choices as they could on location for the fan which I appreciated. Once I gave the go-ahead, they were able to install and clean up within 2.5 hours, which is must faster than I expected. Very professional, courteous, and cleaned up after themselves.

Potential cause of the problem was detected and further test is being performed. He'll be back to run another test to finalize the real cause and location of the problem. Right now our AC is working and giving us cool air. Hoping that it's not a major major problem later on. Thank you guys for your service! Will see you in couple of weeks!
