  • I would recommend this business

They took care of us as soon as possible - same day and before it got too hot. Called several other places that never returned the call! Sam answered the phone and made me feel like he was personally going to see that my issue was taken care of immediately. Great personal service. Omar identified the problem right away and fixed it and gave us good advice on filters in the attic versus the house.

Customer Testimonials

We have had the opportunity to work with Service First for years, our first experience with Service First was when they came to our home to address a problem that had already cost us substantially.
3 other companies tried and failed to turn up a solution.
Service First found the issue, fixed the issue, and charged us fairly for the work.
Since then they have continued to work with us to provide a solid plan for our business and residential needs.

The Technicians have always been courteous, and respectful when they come to our home or are helping our staff with AC problems at our place of business.

Thanks for the great work.

First off, Service First was able to see me 30 minutes after I called. You don't get that kind of service from my experience. As soon as I made the appointment, I received a call about 10 minutes later informing me that Miguel, the technician, was on his way. Impressive!

Once Miguel got here, he spent a lot of time educating me on the system, helping me understand through a logical thought process on how to test the system and identify the problem. He was very knowledgeable and looked at the system from multiple angles before coming up with his diagnosis. He got the system up and running and gave me the information I needed to make an educated decision on what to do with my heater in the future.

Thanks, Miguel. This was a great first experience with Service First. You outdid yourself and really put Service First on the map as a trustworthy HVAC service provider. You deserve to be commended for all your hard work this winter without letting quality slip. You really do put the customer first.

Amazing company. Rudy arrived at 9:00 PM and patiently explained the issue with my AC and my options. It was 98 degrees in my house. The next morning Johnny and Javier arrived with a new system. I am most impressed by how highly the technicians spoke of the owner. This is a sign of a great company. Treat the employees great and they will treat customers great. It was well over 110 degrees in the attic. Johnny and Javier never complained. They even kept a great attitude while they worked through a technical issue. In less than 24 hours, and a completely new central air system later, I am sitting in my 73 degree house. I am more than satisfied, I am impressed.

The a/c went out and our home was hot and very miserable. We called Service First and we were able to schedule them the same day to come out between 8pm and 10pm and they arrived promptly @ 8pm. Thank you Rudy for your professionalism and for doing a great job! He had our a/c working in no time! Go to know that when this emergency....there was a company we could count on in our moment of distress!!

I have had the best experiences with Service First. They are a great company and I would recommend them to anyone. My technician, Rudy, has been out several times now, and has done excellent and exceptional work. He is always very friendly and courteous as well. Service First sent him out pretty much immediately after I called. He is an honest man and this is an honest company. Thank you Rudy, and thank you Service First!

I can't say enough wonderful things about this company! After getting the run around for 2.5 days from 2 other well known companies (John Wayne and Will Fix It) I called Service First at 1:00 am on a Sunday morning. (Memorial Day weekend) They answered the phone immediately and said a technician would be here in 20 minutes. It was storming outside by the time the technician, Adrian, got here but he got here in 15 minutes and had our AC cooling our house within 30 minutes! After all the multiple phone calls from the other 2 companies promising someone was on their way for over 2 days we were extremely happy that Service First not only came out but under bad weather conditions, after 1 am on a Sunday and had our AC working in under 30 minutes....oh, and the bill was about half of what we expected it to be. I'd say service like that can't be beat and is extremely hard to find these days! I will recommend Service First to everyone and will continue to use them whenever we need AC service! Thank you, Adrian, for coming to our aid when the other companies let us down.
