Why Relays Fail and How We Replace Them

Relays are electromagnetic switches that cycle on and off constantly, eventually wearing out due to electrical arcing and mechanical stress. At AB Heating and Cooling, we use proper diagnostic equipment to accurately identify failed relays rather than replacing parts unnecessarily. Failed relays can prevent your system from starting, cause intermittent operation, or create clicking sounds without actually powering components. We use quality replacement relays rated for the correct voltage and amperage for your specific HVAC equipment. Our experienced technicians also inspect related electrical components like contactors and control boards that work with relays, addressing any underlying issues that may have contributed to the failure.
