🚨 ANOTHER HOSPITAL EMERGENCY SERVICE CALL! 🚨

The Welsh Air Systems team responded immediately to a sterile processing room that was alarming and not maintaining proper negative room pressure.

🏥 These critical spaces are designed to maintain negative pressure to control airflow and help isolate contaminants from surrounding areas. When the pressure is out of range, it needs attention fast.

After troubleshooting the system, we determined there was a lack of exhaust airflow from the room. We located the exhaust fan on the roof and found the culprit:

🔧 Worn/loose drive belt
⚙️ Minor fan adjustments needed
💨 Insufficient exhaust airflow

We replaced the belt, made the necessary adjustments, balanced the airflow, and brought the room pressure back into the acceptable range. ✅

And here’s a good maintenance reminder: loose belts don’t just slip—they polish pulleys to a mirror shine! A small maintenance item can quickly turn into a critical airflow problem.

🚨 Critical environment. Immediate response. Problem solved.

🚨 CHILLER DOWN — LARGE EVENT IN PROGRESS!

Today, the Welsh Air Systems team received an emergency service call for a chiller down with no A/C during a large event.

⏱️ We responded within 45 minutes and quickly found the issue: the chilled water flow switch was out of calibration and not sensing water flow, preventing the chiller from operating.

🔧 We recalibrated the flow sensor, restored proper operation, and blew down the chilled water pumps for good measure to help ensure proper flow throughout the system.

❄️ Chiller back online. A/C restored. Event back in business!

When critical equipment goes down, response time and accurate diagnostics matter.

🚨 THIS is why maintenance & inspections matter! 🔧❄️

While performing a routine maintenance and inspection, we noticed excessive bearing noise coming from this fan motor. We pulled out the camera to document the noise for our customer and recommend replacement… and caught the fan failure happening on video! 😳🎥

What started as an abnormal noise quickly turned into a complete failure right in front of us.

Catching problems like this before they cause additional damage or an unexpected shutdown is exactly why preventative maintenance is so important. 👀🛠️

✅ Inspect
✅ Identify
✅ Document
✅ Recommend
✅ Prevent unexpected downtime

Don’t wait until your equipment quits to find out there was a problem.

🚨 ANOTHER RESTRICTED FILTER DRIER! 🚨

The Welsh Air Systems team is replacing another severely restricted filter drier caused by improper installation practices from another contractor. 🔧❄️

When proper procedures aren’t followed during installation—especially while brazing refrigerant piping—contamination and oxidation can be introduced into the system, eventually creating restrictions and costly problems. ⚠️

We’re correcting the issue, cleaning up the refrigerant circuit, and getting this system back to operating the way it should. 💪🧰

Quality installation matters just as much as the equipment you buy.

And remember…
