Strange Odors

If you notice an odd or musty smell, it’s important to call Crystal. You could simply need new air filters, but it could also indicate stagnant water in your system, overheating parts, or a gas leak. To keep your employees safe and prolong the life of your air conditioner, it’s worth it to get it checked out.  

Inconsistent Air Flow

Do you have some offices that are cool while some are stifling? There could be leaks or cracks somewhere in the building’s ductwork. We will work quickly to locate the problem so everyone can enjoy the same level of comfort.

Extreme Energy Bills

Running a business is not cheap, so you’ll definitely feel the burn if your utility bills start to rise. Whether your commercial air conditioner was improperly installed, sized incorrectly for your space, or lack of maintenance is causing it run less efficiently, we will figure out the problem and fix it.


If your units are shutting off abruptly, there could be electrical components that are overheating and causing blown fuses. We can check your system to determine why this electrical issue is happening so your business can stay up and running.

Water Damage

The drain line is supposed to route excess water and condensation away from your HVAC unit, but if the drain line accumulates dirt, debris and algae, it can get clogged. This causes water to back up into the drain pan, which can eventually leak out. During regular maintenance we check and clean drain lines, but if you notice water damage on your ceiling, walls or floors, make sure to call us.
