Call dispatch: (956) 555-0199 Shutoff guide
  1. 01

    Water pouring in

    Find the curb meter box out front or the main ball valve by the water heater and turn it a quarter turn until the lever sits across the pipe.

    Shut off first
  2. 02

    AC blowing warm with ice on the line

    Set the thermostat system switch to OFF and the fan to ON. That thaws the coil instead of burning out the compressor while you wait for us.

    Thermostat off
  3. 03

    Rotten egg smell near the furnace

    Do not touch a light switch. Get everyone outside, then call our line or 911 from the street. We treat gas calls as first priority.

    Get out, then call

Reviews from homeowners and facility managers across Hidalgo County, shared after the job is complete.

Emergency AC Repair

Our AC motor seized on a Sunday afternoon when it was 102 degrees out. Castillo's emergency dispatch arrived in 38 minutes with the exact capacitor and fan motor in the truck. Upfront price was honored to the cent.

Dr. Ronald Garza North McAllen

Whole-Home PEX Repipe

Two other plumbers wanted to tear up our hardwood flooring for a slab leak. Carlos Castillo scoped it with a camera, found the line, and rerouted everything through the attic in one day. Outstanding workmanship.

Elena & Hector Cantu Edinburg

Commercial Tankless Conversion

Our bakery's water heater failed at 5:00 AM before our bread bake. They had a commercial tankless unit delivered and firing by 8:30 AM. Saved thousands in spoiled dough.
