Arrived in Smithville for AC Repair, Upon my arrival I performed a 6 month checkup on one straight cool furnace system. Before starting the evaluation the customer asked that I look into a beeping sound coming from the attic space. I found that the leak breaker on her water heater is the alarm she is hearing. This has nothing to do with any of our equipment and she will be calling a plumber to take a look at it. Completing the evaluation I replaced the cartridge for the iFLO pro and found everything to be operating properly in on the performance and safety aspects of the equipment.
