    As a large company, we connect directly with Christian Brothers for our HVAC needs when our in-house team needs the support for installs. I work directly with Dave and Adam from the estimation process, Daniel from the field troubleshooting aspect and Gilbert for field installations. All members of their respective teams have been very professional and hold safety to the upmost priority which is huge in my line of work. I would highly recommend Christian Brothers as an HVAC solution.

    Called this business regarding the AC to our Sales Dept no longer working. I Spoke with Chad, was super professional and polite! He patiently walked me through some basic troubleshooting and when that didn't work they got someone out much quicker than I expected! The technician Greg was on time and quickly corrected the problem, would definitely use this company again.
