Is this an HVAC emergency?

It is urgent when a failed system threatens health or property. It can usually wait for a normal appointment when the home is safe and only less comfortable.

Emergency HVAC in South Gate: pick your system

What happens when you call us?

We ask what the system is doing, what kind it is and who is at home. We give you the next available opening during business hours. Then we arrive with the tools, find the fault, explain it plainly and give you the price before any work starts.

What if we are closed?

Nights and Sundays, use the safety steps on the emergency AC and emergency furnace pages. Life-safety problems always go to 911. You can also send the request form and we will call back during business hours.

We work from Paramount Boulevard, which keeps Paramount, Downey and Lynwood close. Traffic and the schedule still set the actual arrival, so ask when you call.

“Dealing with an AC that wasn’t blowing cold air during a heatwave was awful. Thankfully, they recharged my refrigerant and had it cooling again in no time.”

Emergency HVAC questions

Does Proair offer emergency HVAC service overnight in South Gate?

No. Our hours are Monday to Saturday, 9:00 AM to 5:00 PM, and we are closed Sunday. We say so plainly, because a false promise helps nobody at midnight. For a gas smell, a carbon monoxide alarm or anyone in medical danger, call 911 first.

What counts as an HVAC emergency in a South Gate rental?

The same risks apply: no heat or cooling with vulnerable people at home, gas, burning smells or water through a ceiling. Tell your landlord right away, in writing, with dated photos. About 54.7% of South Gate’s occupied units are rented, and the lease usually says who arranges repairs. Tenant attorneys or LA County’s tenant resources handle disputes.

Should I shut off my HVAC system during an emergency in South Gate?

Yes, in most cases. Turn it off at the thermostat if it is making grinding noises, tripping a breaker or blowing warm air, because running it can turn a small fault into a compressor failure. For a burning smell, also turn off the breaker. For gas, skip all of that and get outside.

Heat or cooling out right now?

Call Proair during business hours, Monday to Saturday, 9 to 5. Closed Sunday.
