Marietta Commercial AC Repair

Critical HVAC Systems is proud to be a top provider of Commercial AC Repair in the greater Atlanta area. From new installation, to AC Repair to ongoing maintenance prevention programs, we make sure all your HVAC needs are met.

We take a preventative approach to solving our customer’s problems.  However, even with the best preventative maintenance measures in place mechanical device will fail at some point.  When it does, we work with our customers to provide the least cost solution for their business.  We refuse to nickel and dime customers with unnecessary repairs or bait and switch tactics.  We take every effort to provide the best long-term solution, and are often able to repair equipment other providers have condemned.

When repair efforts have been exhausted or are no longer cost effective, equipment replacement becomes the best option.  We will work with you to develop a plan to quickly and efficiently replace your equipment in the lowest cost, least intrusive manner to your business.  This normally happens when projected repair costs exceed 30% of the cost of a new unit, and the unit has surpassed 50% of its useful life expectancy.  We attempt to avoid this at all costs, but will provide ROI analysis and multiple options allowing you to make the best decision for your business.
