  2. Expertise and Trust: your HVAC system is probably one of the most costly items in your home and you don’t buy one every day. See what your San Marcos neighbors are saying about our 5 Star Services over the last 3 decades.

I called the customer to let them know I was on the way, and they informed me that the system was throwing a code. When I arrived and turned the power back on to the system everything fired up and ran without turning off for 30 mins. I contacted the customer to let them know and offered our maintenance plan. They declined maintenance and will contact us if any more issues arise. System operational.

After performing the diagnostic on the living room system, I found that the primary drain line was backed up and tripping the safety float switch. I presented my findings to the client and proceeded to complete the repair on the drain. After the drain system was working properly again, I tested the system and then found that the battery capacitor had failed and was not sending the correct voltage to the motor and compressor. I presented the clients with their options, and they chose to have the capacitor replaced and sign up for maintenance on both systems. I completed the capacitor repair and the system is now fully operational.

Re-piped the primary drain line and installed a new safety float switch. I also installed a ball shut off on the other drain that ties into this one for clearing purposes. Cleared and treated the drain line and everything is draining properly at this time. Also found that the other system that controls the back offices is extremely undersized on return air. I informed Justin and I will be discussing with our Service Manager to find a good solution for this issue. We will send over an estimate in the next day or so.

After performing the diagnostic, I found the water was inside the wall at the floor level and the AC system was upstairs in a closet. The drain was not backed up, so I have determined that the AC is not the issue. The customer will call a plumber to further diagnose.

After performing the diagnostic, I found that the system that controls the back office is a solid block of ice and will need to thaw naturally before we can determine the problem. I also found that the drain for the system behind the bar is backed up and we will need to re-pipe it to clear and treat. They are going to call the owner and get approval for this, and we will complete the work when we return to take a look at the other system.
