JMS Air Conditioning and Heating

Very professional and responsive. Other duct installers refused to perform the service during summer months but JMS gave us a reasonable quote and start date. Ultimately, the date was postponed for one day by JMS, but this didn't cause us any inconvenience. The work was done quickly and quietly, improving the air flow throughout the house and increasing the efficiency of our AC system, resulting in a small decrease in energy costs.

Their price for this was fair and the guy doing the work was professional and friendly. However, it took me several attempts to get these guys to come out here. There were at least two appointments that they completely ignored or missed and these are days I took time off work to come home early. They didn't give me any reasonable explanation. The guy who gave me a fairly high quote on an entire system install using a mediocre brand and its the only brand they sold. I eventually went with another company and got a much better price on a more comprehensive, higher quality system. I would say shop around before using JMS.

Very well! They went above & beyond to insure passing grades for efficiency and local permits.

Great! I'd work with this company again.

JMS team arrived right at the agreed upon time to replace the faulty coil. They used tarps to protect my wood floor and also wore "booties" when in the house. Menooa and Victor were very neat. Menooa kept me informed as the work progressed. Ohad, the project manager called the day before the work began to ask if I had any questions and also followed up with me after the work was done. JMS mailed me the warranty on the parts and labor so I would have for my records. I will use them again in the future.

I am the property manager of an older Spanish-style duplex in the Miracle Mile, and one of the EXTREMELY old furnaces needed to be replaced, so the owner decided to replace both of them with modern forced-air units, which also required bringing the heating systems up to code. This required some serious new duct work between the basement and two units, which was tricky as each unit occupies a separate story.
I got two companies to come out and give me an estimate. The first company (from Angie's List) would not even touch this job; the basement was too small and tight, and the difficulty of installing two units in the tight space as well as installing the new duct work was just too much, so he turned down the job flat.
However, when JMS came out, the estimator Tony acknowledged that it would be difficult, but it was doable. He submitted his estimate promptly the next day (mid-November). The owner and I decided on a start date the following month (Mid-December), when one of the units was unoccupied and JMS was available for the estimated three days installation time. Ohad, the project supervisor, came to the duplex to take measurements, and the installation began the following week. Communication was clear, schedules were made, and they stuck to them.
The installation team, Manooa and Victor, arrived on time and started doing their thing ? they were very courteous, professional, AND CLEAN! Aside from some unavoidable fine dust that needed to be wiped down or vacuumed, at the end of each day they truly left no trace, and put moved items back in their spots. The tenants were very appreciative. Manooa let me know what was going on, if there were any problems, and how they were doing time-wise. When it turned out that the installation needed an extra fourth day to finish, I knew midway through the third day and could reschedule things accordingly.
After the fourth day each unit had a great new heating system (JUST in the nick of time, as it got really cold over the holidays). However, on New Year's Eve, the upstairs heater ? only two weeks old ? did not work! We called JMS to see if they could come out (on an almost-holiday), and Ohad did! It turns out our old wiring had blown a fuse INSIDE the furnace, so Ohad replaced the fuse and rewired a few things. It is still going strong!
From start to finish, this company was clear, professional, communicative, and responsive. This was a big project with a big cost outlay and the owner had put it off because it was such a pain. However, the entire experience ? which really could have been a big, inconvenient headache for everybody ? went really smoothly. Two big thumbs up!

I contacted JMS for a second opinion after a technician from another local AC company, told me that my problem would require a new electronic board and new motors. I was told that the board and motors were dysfunctional and the entire board and motors needed replacing.  After a $5,000 repair quote, I contacted JMS for a second opinion.
Eduardo R., the service technician, was a godsend! He was honest, efficient, and professional, and had my system operational in less than an hour. A freon depletion was addressed and my total bill was about $500. Eduardo told me that my electronic board and motors were in perfect condition and were not in need of replacement! What a relief!
There are honest businesses out there, and this is definitely one of them! Thank you to Eduardo and to the entire team at JMS!

Great.  He covered a great deal in detail.  He took the time to  make sure i understood everything.   Seemed completely professional and put me at ease.

It went great! Everybody who came to the house was a professional, and clearly well-versed.

Ask for Jeff Berg!! He is one of the best, if not the best technician I have worked with at JMS or anywhere else.  Not only is he extremely knowledgeable about the system, but he is extremely clear and articulate  about the repairs, very calmly discussing what needs to be done and why.  He is also a great salesman for the company --he explained very clearly the cost benefit of becoming a preferred customer (preferred service priority along with other discounts) vs. calling for service on an incident by incident basis.
We have been customers of JMS over the last 18 years --their prices are on the high side.  The work Jeff did on this job was for a rental property for which I didn't want to spend the for premium preferred service.  It didn't matter, however, because Jeff provided A level service --figured out electrical issues, brought the maintenance up to speed and got the whole system working perfectly again.  
I will continue to work with JMS in the future.  Jeff did a great job!

Marco B, the service man, arrived early.  He was very friendly and got right to work, offering to help me clear an area that he needed access to.  I retained their services after receiving a call offering a $49 rate per ac unit.  He was here for a long time.  When it was done, he showed me a photo of mold that had accumulated on one of my machines.  He recommended that I install an Air Scrubber system into my AC unit to keep the air clear that runs through that unit.  The machine was very expensive ($1275), but he said he uses one himself because he has bad allergies.  My daughter has bad allergies and asthma also, so I thought it was worth it.  I was also impressed with Marco because he spoke very intelligently about my entire system and even drew me diagrams to make it easier to understand.  He included the cleaning of the mold for free, saving me a couple hundred dollars.  We also discussed the ages of each of my systems and he knew immediately, having taken photos of all dates.  So, even though I spent a lot more than I anticipated, I thought JMS's services was very good and would highly recommend them.

I have been using them for years.  They are reliable and when I need them they come and do it and whenever I had a problem they come out and fix it.  I am a regular customer with them for several years.

They were excellent. They did everything quickly. It was a simple job, but they were fantastic.

That service turned out excellent. I was very pleased with the entire set up. They were accommodating and I am hoping that the unit works as good as it looks, I have not got to use it yet.

JMS came to repair my central air conditioning and the technician let me know that the component he replaced wore out prematurely because the system was being over-strained by old inadequate duct work. Years ago when we upgraded our central A/C with a more powerful unit, the company that did the installation didn't bother to let me know that the old ducts were inadequate for the new system. Neither did other companies that had done repairs in subsequent years.
JMS was the first to alert me to this situation. They replaced the return ducts with larger well insulated ones and the improvement was dramatic. The air flow increased markedly and the whole system is so quiet now that the fan is no longer straining to circulate the air. I am impressed with their professionalism and results.

Very polite, nice guys in the sales phase and installation.  Showed up on time to start, and the work seems well done.  I would use them again, but, the buyer needs to beware, and follow up on everything.

a) Speed of the job was a high priority to me due to temperatures, second only to quality of job.  At time of sale, I was told they could certainly finish in two days, and probably in one if they could work a bit late, say 6pm.  They quit at 3:30 on first day because, according to installers, not all the materials had been ordered.

b) Day 2, I was out running errands, but when I got back at 3:15, they were gone.  It looks like installation is complete except for one item (see next comment).   The guy who is supposed to do "start up" originally would be here when they finished; then, he changed that to around 5pm; then, a call from the office said he'd gone on other side of town, could I be available next day (too many hot nights already).  The system is not yet charged with refrigerant.  I guess none of their team of 3-5 installers can do that.  I asked if someone else could come today and start the system.  The original lead guy came and got it going.

c) At time of sale and taking measurements I was assured that they could get equipment in and out of access port to my crawl space.  Then, it turned out they couldn't and proposed cutting a bigger hole and covering it with plywood.  Not thrilled, I insisted on a proper job of it.  The guy to do this was supposed to come on Thursday, but came Friday, to take measurements.  Piece was finally done and installed on Tuesday.

It looks like the missteps were due to several instances of bad communication across different players.  Nothing that couldn't be fixed, but I needed to follow up on several items to be sure the right job was being done, which is how I discovered the missed communications. 

Would I use them again?  Yes, I would. When all done, I?m pleased with the job, and they were very attentive to following up on a number of things, in spite of the communication slips.
