Customer Testimonials

Extremely professional team, on time and knowledgeable. Our plumber Max was amazing! This team is on our go to list


Raul and Jacob were Very reasonable and understood my position. And we're willing to work with me.They took care of my problems one step at a time to not over burden me.


Superb service! Lorenzo came and completed all the work on the same day that I called. My A/C unit was giving me some trouble on a very hot day. He was eager and confident in the work I had explained that I needed.Needless to say, my A/C was up and running in tip top shape after he came out. I cannot thank him enough for being reliable,honest and having a quick turnaround fix. He didn't even charge me an arm and leg. He was very fair on his fees. After all that, he also called me to follow up with the unit the next day!!! I'm very impressed. Thank you again Lorenzo!


I can't say good enough things about on time Elmer A/C service. My A/C went out and the house was at 80% and climbing. On top of all that my two month old daughter just received her shots and had a fever. I wasn't able to call till 9pm and they were there within 30-40 min. The technicians were able to get the A/C up and running. These guys truly care about what they are doing and really took care of me and my family.
