HVAC Repair Guide for Phoenix Homeowners

No. It is a symptom. Refrigerant circuits are sealed, so if the charge is low it leaked, and the leak is the repair. A top-off without a leak search buys the same service call again next month; the refrigerant leak repair page explains how a leak is found.

Long enough to measure. Voltage, amperage, capacitance, pressures with superheat and subcooling, temperature split, plus a look at the drain and the airflow, take real time at the unit. A ten-minute verdict delivered from the driveway is a guess with a clipboard.

Once. If it trips again, leave it off and call, because a breaker that keeps tripping is protecting a motor, a compressor or wiring from a fault that resetting will not cure. The breaker page covers the usual causes.

On a system that age, particularly one running R-22, a compressor repair usually deserves a replacement conversation first. That is arithmetic rather than a sales script, and the repair-versus-replace guide lays it out. The final answer depends on the condition of everything else, which takes an on-site look.

That is your call and we will honor it. We will tell you if the failed part was a casualty of another weak component, because replacing a capacitor without noticing a dragging fan motor tends to mean a second visit. Then you decide, with the numbers in front of you.

Yes. Most of what fails on a split system fails on a package unit too, only hotter and on a roof. Leave the ladder to us; the rooftop unit guide explains how these systems differ.

It can tell you what usually is. It cannot measure your system, and Phoenix systems tend to fail in combinations. Use this guide to ask sharper questions, then have a technician put instruments on it.
