Frequently Asked Questions
What does a contactor do?
It’s the switch that turns your outside AC unit on and off when the thermostat calls for cooling. Bad contactor = AC won’t turn on, or worse, won’t turn off.
Do ants really cause contactor problems?
Yes, more than you’d think in Tampa. Sugar ants and crazy ants nest inside the housing. Their bodies short the contacts. We find ant-damaged contactors weekly from June to October.
Is contactor replacement the same as capacitor?
Different parts, same $279 flat price. Capacitor = starts compressor. Contactor = switches power to compressor. Both can fail independently, sometimes together.
How long does replacement take?
30-45 minutes typical, including diagnostic. Same-day service across Tampa Bay.
Will replacing the contactor fix my AC?
If the contactor is actually the issue, yes. We diagnose first to confirm, we won’t sell you a part you don’t need.
How do I prevent future contactor failures?
Annual maintenance (Therapy Plan member pricing 15% off) catches early pitting. Surge protector ($469) prevents storm damage. Sealing outdoor unit prevents ant entry.
