“The Mystery Clicking Sound: How a Smart Thermostat Uncovered a Hidden Heating Problem”

December 30, 2023 Heating, HVAC Installations, Uncategorized - 0 Comments

Imagine coming home to a warm house every day, only to be greeted by a mysterious clicking sound. That’s exactly what happened to one of our customers who recently installed a Nest 3rd Generation Learning Thermostat. While the thermostat seemed to work fine at first, there was something lurking in the basement that needed our attention.

Our customer, Mr. Johnson, called us in distress. He explained that his newly installed Nest thermostat was causing a strange clicking noise in his mechanical room whenever it reached the desired temperature. Concerned, we sent one of our experienced technicians to diagnose the issue.

Upon inspection, our technician discovered that the issue lay beneath the surface. There was an ARGO Control Switching Relay (ARM-4P) installed in Mr. Johnson’s system, and these control boards are not compatible with Wi-Fi thermostats like the Nest.

To resolve the problem, we recommended adding an Isolation Relay, specifically the ARGO IR882. The theory behind this solution is to prevent the thermostat from drawing power from the existing control board, eliminating the clicking sound. Below is an image showing our connections.

Benefits of the Solution and Repair heating System:

  • Silent Comfort: The ARGO IR882 ensures that your heating system operates silently, without any mysterious clicking sounds disturbing your peace.

Our experienced technician, Wilson S., with over 10 years of HVAC expertise, handled Mr. Johnson’s case with precision and professionalism. He knew exactly how to diagnose the issue and recommend the right solution.
