We have been doing business with Zimmerman A/C for 40 years. We started with the founder Larry Zimmerman honest, hardworking, and a true craftsman. His son Luke carries on his legacy. They recently replaced a unit for us their crew arrived put down tarps covering the walkways they were using and installed the unit on a very hot September day. Afterwards I saw them vacuuming the whole walk way even though it had been covered I told them they didn’t need to do that as they had been up in the heat of the attic all day his response “it’s part of the job sir!” Also Carla in their office worked the schedule to get the install done sooner as we were expecting a visit from our kids. Quality American Standard products, honesty and craftsmanship (the unit they removed was put in by Larry, Luke’s Dad 19 years ago!) Great people I highly recommend them and won’t let anyone else touch my HVAC systems!

Spent over $15,000 and they didn’t install our AC unit correctly. We’re having ceiling leaks and water dripping outside our house. They put the drainage through our sink, which I believe is against state regulations. When there is a storm, our AC quits working for some reason because of the rain. It has caused extensive damage to my house. This is what happened to the ceiling— 4-6 years after the improper installation.

I love the assurance of having very skilled and professional people work on my air-conditioning units! Caleb with Zimmerman air-conditioning did an outstanding job of maintaining the units, explaining any findings, and then relaying options to me to make my units even better. He was very polite and well spoken.He’s a true asset to Zimmerman AC and I will be requesting him for our next maintenance visit next spring! Thank you Caleb! You deserve a raise!

Great experience with Zimmermann every time. Technician always explains every step and reason for repairs or service. Texas heat is miserable and everyone I know has their HVAC die at some point over the summer. But Zimmermann is always quick and friendly, unit back in service and pricing is always spot on.
