It ensures consistent evaporator coil temperatures

We recommend reusing existing OEM clamps or sourcing new stainless steel spring clamps to ensure a leak-proof connection to the condensate trap

preventing unnecessary wear on the outdoor condenser unit

Improved System Efficiency: Modern spark ignition pilot technology eliminates the gas waste of constant-burn standing pilots

Most 40VA transformers fail due to a downstream short in the 24V wiring or a seized contactor coil pulling excessive amperage
