What Our Clients Say

Just got a complete residential AC/Heater system installed by Matt, Brandon and James of Sig Cox. They were professional, on time, responsive, helpful, friendly and courteous. They were preceded by an excellent tech to diagnose my problem and by staff in the Augusta office - sales, business/admin, even staff from the commercial side, who got the ball rolling!

After an expensive false start with another contractor and two stressful, hot days, Sig Cox helped me be confident about what the problem was, my options and my final decision,...and the installation crew more than confirmed my decision!
- Mark Inouye
SigCox was excellent! We had an issue and Doug Coleman was able to get a tech out to us quickly. Cory was a very nice, informative, and knowledgeable tech that took care of the issue quickly and had our lower unit up and running.

I highly recommend sigcox.
- Jennifer Gillahan
Brandon and Josh did a wonderful, professional job with the installations of our new HVAC system. Beginning with the presentation of options from manager Doug Coleman to the total cleanup and removal in our garage, the process was expert and seamless.

Always on time and reliably keeping us in the loop at every stage, the experience could not have gone better. I would recommend them to anyone.
- Helen Vaughn
We have been using Sig Cox Heating and Air Conditioning to maintain our HVAC system and do the repairs if needed for a few years now. They are very responsive, professional, timely and do a good job overall. The technicians that come home take their time, explain the process they work on, give recommendations and direct us to get the best use of our system.

Corey completed our maintenance twice and he has been very professional and thorough. I have been satisfied with the other technicians by this company also. Highly recommend them!
- Duygu Minton
I had an issue with my system and being from out of town thought it would be a hassle. But dealing with this company made it so easy.

From the manager to the technicians, it was all handled so professional and the people were helpful and courteous! Definitely happy I chose to use them!
