Turn Off Power

The first step in any HVAC repair before beginning any repair work, a Fix-It 24/7 technician will ensure the power to the AC unit is turned off. This can typically be done by switching off the circuit breaker dedicated to the HVAC system.

Identify and Inspect Components

The first thing an expert HVAC technician at Fix-it 24/7 takes is a close look at the components of the zone panel. They verify wiring, electrical connections, and the circuit board. They look for signs of damage such as burnt wires, loose connections, or any visibly damaged parts.

When an AC zone panel breaks, it is often times due to a short from a “hot” wire touching a ground-wire or a spike in voltage.

Disconnect Wires

Fix-it 24/7’s licensed HVAC technician starts by disconnecting the main power source by removing the wires connected to the zone panel. Using caution, they ensure the wires are not touching any metal surfaces or other wires. They test the voltage of the wires to make sure the system is powered off.

Connecting Thermostat

After the power is turned off and the system is safe to work on, the thermostat is wired to the AC zone panel. This is so the thermostat can tell the unit what temperature the home is requesting so the panel can get the house to the right temperature.

Remove Static Pressure Sensors

Two sensors are involved: discharge and return air. The discharge sensor measures the air temperature exiting the unit, allowing for proper regulation. The return sensor detects the indoor air temperature, providing valuable information to the unit. In some cases, a return sensor may be unnecessary if the thermostat provides accurate readings. However, an inadequately insulated attic can affect return air temperature and accuracy. This unit required both a return sensor and thermostat input for improved accuracy due to the well-insulated attic.

Reconnect Wires

The technician will begin to connect the main power source wires to the appropriate terminals on the zone panel. They will ensure each wire is securely fastened and properly matched to the correct terminal. Starting with the discharge and return air sensors, then the thermostat wires for the AC zone control dampers, and then finally the AC condenser wire.

The wiring is zip tied to keep it neat. If the wiring moves around, it can touch which causes an electrical short and subsequently a breakdown.

Flood Switch Installation

Also known as a “flip switch”, this is wired up to the AC zone panel so that it can send error data to the thermostat. The flood switch monitors if the AC unit is flooding and is a failsafe to prevent further issues.

Perform a Function Test

Once all the wiring was connected, Fix-it 24/7’s expert HVAC technician turns the power back on to the AC unit. We ensure that the CDA, the brain to the unit and what controls functionality, is communicating data. We then perform a function test to ensure the AC zone panel is functioning properly. They will also check if the temperature control and zone settings are responding as expected.

Calibration and Thermostat Initialization

After power has been turned back on, the technician calibrates the AC zone panel settings with the thermostat. This ensures accurate temperature control and zoning.

On the thermostat, there were two new error codes. The AC zone control system needs to be recognized by the system. In the thermostat settings, the technician normally removes the old AC zone panel to add the new one. In this instance, the thermostat was reset to default settings because the old system was not removable otherwise.

Once the new zone control system was set up, there were new error codes pertaining to the outdoor unit. The thermostat was unable to communicate with the outdoor zone. To remedy that issue, the outdoor condenser was run through a cycle. By removing the plunger on the electrical disconnect which kills power to the unit, it reset the air conditioner.

Secure Zone Panel Cover

Once the repair work and testing were complete, the technician went back up to the attic where the AC zone panel is located. There, the technician finalizes all the wiring and securely fastens the zone panel covers back in place. They will ensure that all screws are tight to prevent any loose connections or potential hazards.

They will verify that the zone panel is functioning correctly and provide the desired temperature control in each zone, specifically looking at the return air and supply air temperature. The supply air temperature (outdoor) was 75 degrees and the return air temperature (indoor) was 57 degrees.
