    For suction line temperature at the coil? That'd work. I would have it break the call to the compressor though, not the AHU. Reason being, you'd still want the blower to run so the evaporator can...

    Did any of these "contractors" look at the duct work or check airflow? You could have a collapsed return somewhere, coil could be dirty, blower motor not performing to specs, etc.

    Best way to prevent freezing up is changing filters often, keeping all registers open, and having your systems serviced once a year. Installing pressure switches probably isn't cost effective if...

    I wouldn't ask the homeowner anything, what do they know?

    Pop the panel off the coil and inspect yourself to see if it has a piston or TXV - every time.

    What was your temperature split?
