Isaac and Wilson diagnosed and fixed my heating unit quickly and efficiently. They were both professional and resprctful.
OUTSTANDING service. Faced with some obstacles, they took the time to sort everything out and properly charge my ac system and instal my new Nest. Could not be more pleased.
Tina of JMS has alway been helpful and friendly. The service technician Raymond is a true professional and sincere. Thank you for the excellent service. —-Robert B.
Thank you guys for coming and changing my old thermostat for a Nest and also for changing my old A/C filter. Isaac did a wonderful job explaining to me how to use the new thermostat and also gave me good advise and recommendation about my A/C unit. Not to leave aside all the test and analysis he did on my info unit to check if it was running efficiently, he also cleaned the coil of my old unit. If you guys want a reliable and professional service, don't hesitate and give them a call.
Very professional and personable.
Isaac was very helpful.
We just used JMS for the LADWP AC optimization program and our technician Isaac was so courteous, thorough, knowledgeable and professional, I was absolutely thrilled with the exp. He took the time to install and explain everything in full detail and made sure he was as neat as possible without me having to ask. He was a great reflection of the company and I hope to use them in the future for all my HVAC needs! Thank you JMS for your help!!! ??????????
Great service. Came on time, set realistic expectations about how long it would take to get everything done, talked me through what was being done and most importantly the tech properly did everything and confirmed it was working before leaving. Would not hesitate to recommend.
Isaac was very Good and Helpful, Im happy I called JMS. I would use them again.
