JMAC repaired our AC. They were informative, professional, kind and thorough. We had been using another AC company prior but decided to try JMAC because of all the great reviews. We have received the best service from Tanner, Brandon and Brent. So happy to have found a company that cares about doing great work and treating their customers well.
Lisa A.HVAC System Repair5 months ago Zach was my technician, excellent service. I actually met Zach 18 months ago at a client's house. Saw the excellent work he was doing for them and took a business card. Zach showed up to my house today. The service was excellent, the price was amazing. Thank you again.
Brad H.HVAC System Repair2 months ago Zach was awesome. Very knowledgeable and honest. He walked us through every step of what he would be doing during his visit and clearly explained our next steps. At no point did we feel like he was trying to take advantage of our situation. We will definitely recommend Zach and his company moving forward.
Emanuel S.HVAC System Repair4 months ago Showed up on time. Conducted themselves with professionalism in appearance, attitude, and job knowledge. Replaced my entire system in 5 hours. They answered all my questions and concerns. Price was competitive. Definitely recommend them to anyone needing AC services.
Ty C.AC Installation & Replacement3 months ago It was a fabulous experience, very professional polite workers. Craig greeted us and called me by my name all day long. We would highly recommend your company for repair or new installation.
Jamie W.AC Installation & Replacement8 months ago JMAC came exactly when they said they would for the install of 2 new heat pumps. They were very professional, polite, courteous, and cleaned up afterwards. It was an all day install of the 2 units, but they were done when they said they would be done. I highly recommend this company.
Susan B.Heat Pump Installationa month ago Zach was wonderful. He diagnosed the problem explaining what was wrong and what part needed replacing. He installed the new part and my A/C is running great. Zach was knowledgeable, courteous and professional. I will always call on JMAC for all my AC needs.
Sandra P.AC Repair3 months ago Brandon did an incredible job recognizing that it was a thermostat issue and not an A/C problem. Fixed in a matter of minutes. Always very professional and helpful.
Chad P.AC Repaira month ago Just came home from the hospital with my two day old son. Once we walked in the house, we found out that our air conditioning had broke. I called the 'emergency' HVAC company that the builder told me to contact. Even after I stated that there was a two day old baby in an 86° house, they told me they were unable to help me until later in the week. Jake came out and diagnosed the problem that same night. He then returned the next day with the new part and worked into the night to make sure my air conditioning was working for my wife and my newborn baby. JMAC has gained a customer for life.
Issac B.HVAC System Repair4 months ago Exceptional customer service throughout the entire process. We've had our units serviced by JMAC throughout the years and it was time to replace one. It was simple, affordable and we couldn't ask for a better experience.
Christian K.AC Installation & Replacement2 months ago Zach did a great job servicing our AC units and only did what was necessary. Absolutely no pressure to buy anything that was not needed. In fact he said we were doing well for a year or two.
Keith M.HVAC Maintenance5 months ago After much research using the certified companies through American Standard I chose JMAC to inspect my HVAC system. JMAC sent out Zach who was extremely professional and explained in detail on the inspection. After finding no issues, I was pleased with the service. Would recommend to anyone looking for a reasonable and educated HVAC company.
