We went out to a service call for a local business this week that two other companies told them that they had a refrigerant leak in their evaporator coil and that they needed to buy a new system. Opened up the system and found the cause of their low pressure to be just a plugged up and dirty evaporator coil.
A dirty evaporator coil can cause you to have low pressures that can make it look like you may be low on refrigerant as well as it can cause the system to freeze up. When diagnosing a system you have to always check the airflow before the refrigerant charge, without proper airflow the refrigerant charge doesn’t matter.
After a good cleaning of the coil and the blower assembly this system was back up and running properly and cooled down the space in no time.
As a small family owned hvac company we believe in quality over quantity and take plenty of time on each call to properly diagnose and provide cost friendly options. In this case we saved this customer thousands and got them up and running in just a few short hours.
For all of your comfort needs give us a shout at 830-358-6209, we would love to show you what On Point service looks and feels like.
