Busy day on the rooftop keeping commercial equipment running strong. 🔧❄️☀️

Worked on two rooftop units today troubleshooting compressor trips, checking electrical components, and inspecting overall system operation. These older RTUs still have plenty of life left when they’re properly maintained and serviced.

Preventive maintenance and fast diagnostics are key to avoiding costly downtime — especially heading into warmer weather.

If your commercial HVAC equipment is struggling, tripping alarms, or not keeping up, give Critical Heating & Hydronics LLC a call. We service residential and commercial systems.

Performed diagnostic evaluation of a residential air conditioning system due to evaporator coil freeze-up condition. Found restricted airflow caused by dirty air filter resulting in low evaporator temperature and icing of evaporator coil. Replaced air filter and allowed system to thaw and stabilize. Verified refrigerant pressures, superheat, subcooling, temperature split, and overall cooling performance. Added 0.6 lbs of R410A refrigerant to optimize system operation. System operating properly at time of service with acceptable cooling performance and humidity removal observed. Recommended continued monitoring of system operation and routine air filter maintenance.

Responded to a failed bearing assembly on a pump—caught it before it turned into a much bigger (and more expensive) problem. Removed the damaged components, installed a new bearing assembly, aligned everything properly, and verified smooth operation before putting it back into service.

These are the kind of issues that can sneak up if equipment isn’t being regularly inspected. A little noise or vibration today can turn into major downtime tomorrow.

If your system doesn’t sound or feel right, it probably isn’t.
