During a recent heat wave in Crystal Lake, Illinois, our team completed an emergency next-day air conditioning replacement for a townhouse where the cooling system failed during extreme outdoor temperatures.
The project started as a regular maintenance visit. During the inspection, we found that the air conditioner was not operating. After testing the system, we confirmed that the compressor was shorted to ground. In simple terms, the compressor had failed internally and was no longer safe or practical to repair.
AC Failure Found During a Maintenance Visit
This happened during a period of extreme summer heat, with outdoor temperatures reaching over 100°F. For the residents, living without air conditioning in those conditions was extremely uncomfortable and potentially unsafe. Because of the urgency, we offered a next-day replacement of the outdoor air conditioner and indoor evaporator coil.
The following day, our team returned to the townhouse in Crystal Lake and completed the installation in about four hours. We installed a new high-efficiency Sinclair air conditioning system with the new R-454B refrigerant, replaced the indoor coil, and installed the required A2L mitigation board for the new refrigerant system.
New Sinclair High-Efficiency AC System with R-454B Refrigerant
After the installation was complete, we started the system, checked operation, and confirmed that cooling was restored to the home. The new system was running properly, and the residents had air conditioning again the same day.
This project is a good example of how important it is to act quickly when an older air conditioning system fails during a heat wave. In some cases, a simple repair is enough. But when a compressor is shorted to ground, especially during extreme weather, replacing the system may be the best option for safety, comfort, and long-term reliability.
Cooling Restored in About Four Hours

What happened during the maintenance visit that led to an emergency AC replacement?
During a routine maintenance visit, the air conditioner was found not to be operating. After testing, we confirmed the compressor was shorted to ground, meaning the compressor had failed internally and was no longer safe or practical to repair.
Why was replacement chosen over repair for the compressor short to ground?
Because the compressor had failed internally and shorted to ground, replacing the system was deemed the best option for safety, comfort, and long-term reliability, especially during extreme weather.
How quickly was cooling restored after the replacement?
Cooling was restored the same day, with the project completed in about four hours after the installation of the new system and components.
What refrigerant and system components were installed in the new AC?
We installed a new high-efficiency Sinclair air conditioning system with the new R-454B refrigerant, replaced the indoor evaporator coil, and added the required A2L mitigation board for the new refrigerant system.
What should homeowners do if their AC stops during a heat wave?
If the air conditioner stops during a heat wave, an inspection can determine whether a repair or replacement is the right solution, and urgent replacement options can be offered when safety and comfort are at risk.
