Industrial Air Conditioning Repair: How to Troubleshoot Common Problems


The invention of the air conditioner is credited to Willis Carrier in 1902. While Carrier’s “Apparatus for Treating Air” was initially created to solve a humidity problem that publishing companies faced, these days HVAC units are a necessity in many commercial buildings.

Part of owning a commercial HVAC system is knowing when to call industrial air conditioning repair services. The best way to determine what service you need is to first troubleshoot the issue. This way you can give the repair service more information about the problem, cutting down on the inspection time.

Low Refrigerant Equals Low Efficiency

If your unit is underperforming, or you’re noticing the air has a sticky quality, your unit might be low on refrigerant. Refrigerant levels are usually only low if there is a leak, or if it was undercharged at installation. Without enough refrigerant, your HVAC unit won’t be able to control the humidity of the air.

Unfortunately, the only way to truly tell if your unit is running low on refrigerant is to have a professional come and take a look. So simply keep an eye on the efficiency of your unit.

If you’re constantly needing to get a tech out to top up your refrigerant, it can be a sign of a bigger problem. This shows that there is most likely a leak that needs to be fixed, and if there are multiple leaks the unit might need to be replaced.

You might also notice changes in the airflow of your unit if you need to replace the filters. Clogged and dirty filters will make your unit work harder to push the air through, resulting in the air not cooling as efficiently.

Ventilation Issues

Ventilation issues can lead to your unit overheating or malfunctioning. If your vents are blocked by debris, the unit won’t be able to properly cool itself down, causing it to overheat.

A simple walk-through inspection will usually be more than enough to address this issue. Once you’ve located the obstruction you can clear it away and your unit will be able to ventilate itself.

If the vents haven’t been set up properly, you’ll need to contact a professional to come and fix them. The best way to determine if this is the problem is to inspect the vents to check which ones have ventilation problems and if there isn’t anything else causing the problem.

Industrial Air Conditioning Repair Made Easy

When it comes to industrial air conditioning repair, it’s always good to know how to troubleshoot common problems. While you should never try to fix an HVAC system without proper training, sometimes you only need to replace a filter to get your HVAC unit working again. Troubleshooting industrial air conditioning shouldn’t be dangerous, so if you’re unsure it’s best to call a professional.
