No cool or heat in the whole home, ran diagnostics on the system. While performing diagnostics found, we are not getting 240 to the air handler or the outdoor unit. Recommend electrician to take a look at the breaker/circuit going into the air handler. While testing found very dirty, blower wheel, very rusty, capacitor to blower, dirty heat strip kit, drain line, ran along the ground, and in a bad condition, extremely dirty, condenser coil, tested and found that the compressor is grounded, causing the breaker to trip and the capacitor is swelled. Based on our findings today, it might be time to think about getting a brand new system.
