AC Contactor Replacement in Central Oklahoma
A burned contactor is the number one reason an air conditioner will not start on the hottest day of the year. I have been replacing contactors across central Oklahoma for 45 years, and every summer the pattern is the same: 100-degree temperatures, the AC stops cooling, and when I open the disconnect there is a contactor with pitted, burned contacts that finally gave out under the load.
Contactors are inexpensive to replace, but they are critical. A buzzing, chattering contactor is not just annoying. It is running your compressor at reduced voltage and accelerating its wear. Catch it early and you save yourself a much bigger repair bill.

Why Oklahoma Is Hard on Contactors
Central Oklahoma summer heat means your AC contactor opens and closes more times per season than in a milder climate. Add in the electrical storms that roll through Kingfisher County from April through August, and you have a recipe for accelerated wear. Voltage spikes from lightning can pit contacts in a single strike. The SureSwitch solid-state upgrade eliminates the pitting problem entirely by using electronic switching instead of physical contacts.
Contactor buzzing? Do not wait until it fails completely. Call 405-375-4822 for same-day service.

Frequently Asked Questions
What is an AC contactor and what does it do?
The contactor is an electrical switch inside your outdoor unit that connects and disconnects power to the compressor and condenser fan motor every time the thermostat calls for cooling. It opens and closes hundreds of times a season, which eventually causes the copper contacts to pit and burn. A bad contactor is the single most common reason an AC will not start on a hot day.
How do I know if my AC contactor is bad?
Signs include: the outdoor unit does not come on when the thermostat calls for cooling, you hear a loud buzzing or chattering from the outdoor unit, or the system runs constantly without shutting off. A buzzing contactor has pitted contacts and is failing. Do not wait until it stops working entirely.
How much does a contactor replacement cost in Oklahoma?
Single-pole contactors run 89-09. Double-pole contactors are 39-69. Three-phase commercial contactors are 29-99 depending on amperage. The SureSwitch solid-state upgrade is 81 installed and eliminates the pitting problem entirely since it has no moving contacts.
What is the SureSwitch upgrade and is it worth it?
The SureSwitch by Emerson is a solid-state electronic contactor with no moving parts. Standard contactors pit from arcing every time they close. The SureSwitch eliminates arcing entirely. It costs more upfront at 81 vs 89-69 for standard, but can last the remaining life of the system with no further replacement. Worth it on newer systems.
Can a bad contactor damage my compressor?
Yes. A pitted contactor with high resistance causes voltage drop to the compressor, which means the motor runs hotter and draws more amps than it should. Over time this leads to premature compressor failure. Replacing a 49 contactor proactively is far cheaper than a ,295 compressor replacement.
Do you charge a dispatch fee and diagnostic fee?
Yes. There is a 9 dispatch fee for all service calls and a 11 diagnostic fee. The diagnostic fee is credited toward your repair or replacement if you accept an estimate within 14 days.
