Heat and dust put extra strain on an air conditioner here.
Long stretches of high outdoor heat leave little room for a cooling system with a small fault. A low refrigerant charge, weak capacitor, failing condenser fan, restricted airflow, or a compressor that is beginning to struggle can go unnoticed in milder conditions. During a Tye afternoon, that same system may run without bringing indoor temperatures down because it cannot release enough heat outdoors.
Windblown dust adds another load at the outdoor unit. Dust on the condenser coil restricts the transfer of heat and raises operating pressure, so a unit works harder even when its mechanical parts are sound. In Tye, we separate a dirty or obstructed outdoor coil from a refrigerant, fan, compressor, or airflow problem rather than treating every no-cooling call as the same repair.
Heat also puts electrical parts under sustained load. We check capacitors, contactors, and wiring connections while the system is operating, because an electrical component that seems acceptable during short, moderate-weather cycles can fail when cooling demand stays high.
