We Answer When You Call

A lot of companies advertise emergency service. Fewer actually deliver it consistently. At Five Star, 24/7 availability isn’t a marketing line, it’s how we’ve operated for nearly 40 years in the Palatine area. When you call after hours, on a weekend, or on a holiday, you’ll reach someone who can dispatch a technician to your home. We know how quickly a failed AC can make a house uncomfortable, and we treat after-hours calls with the same urgency and professionalism as any scheduled appointment.

What Counts as an AC Emergency

Some situations clearly can’t wait: a complete system failure during a heat advisory, a home with young children or elderly residents who are vulnerable to heat, or a cooling system that’s cycling on and off rapidly and showing signs of a serious electrical issue. Others sit in a gray area. If you’re not sure whether your situation warrants an emergency call, go ahead and call us. We’d rather help you make that determination over the phone than have you spend the night in an uncomfortable or unsafe home.

Fast Diagnosis, Not Just a Fast Arrival

Showing up quickly matters, but it’s only half of the equation. Our technicians arrive stocked with commonly needed parts so that in many cases we can complete the repair in a single visit rather than diagnosing the problem and scheduling a return trip. Before any work begins, we’ll walk you through exactly what’s wrong and what it will cost to fix it. Even in an emergency, you won’t be pressured into approving work you don’t fully understand.

Frequently Asked Questions
Is there an extra charge for emergency or after-hours AC service?
After-hours service calls may carry a different rate than standard scheduled appointments. When you call, we’ll be upfront about any applicable fees before dispatching a technician so there are no surprises when the invoice arrives.
Response time depends on current call volume and your location within our service area, but we work to reach emergency calls as quickly as possible. When you call, we can give you a realistic estimate of how long it will be before a technician arrives.
Close blinds and curtains to block direct sunlight, move to the lowest level of your home where it tends to stay cooler, and stay hydrated. If anyone in the household is showing signs of heat exhaustion, such as dizziness, nausea, or confusion, seek medical attention immediately rather than waiting for the AC repair.
