Frequently Asked Questions

Got questions? We’ve got answers

What qualifies as an HVAC emergency?

HVAC emergencies include: no heat in freezing weather, no AC in dangerous heat, gas leaks, carbon monoxide detector alarms, electrical burning smells, water leaks causing damage, or complete system failures affecting safety or health.

How fast can you respond to an emergency?

We prioritize emergencies and aim to have a technician at your door within 1-2 hours. During extreme weather, we work around the clock to help as many customers as possible.

Do you charge extra for after-hours service?

For maintenance plan members, there are no after-hours fees. For non-members, a small after-hours service fee applies, but we believe fair pricing during emergencies is important.

Can you fix my system the same day?

In most cases, yes! Our trucks are fully stocked with common parts. If a specialized part is needed, we’ll provide temporary solutions to restore comfort while ordering the part for permanent repair.

What if I need a replacement instead of repair?

If replacement is the best option, we can often install a new system within 24-48 hours. We’ll discuss all options, pricing, and financing to help you make the best decision.

Are emergency repairs warrantied?

Absolutely! All our repairs come with a warranty on parts and labor. We stand behind our work whether it’s an emergency call or scheduled service.
