AC Repair in Tomball & Spring, TX

Common AC problems we fix

Houston-area systems run hard most of the year. Here’s what a failing AC looks like, what’s safe to check yourself, and where we start.

• AC running but blowing warm air

  The fan moves air, but it isn’t cold. Common causes are a dirty filter or coil choking airflow, an outdoor unit that isn’t running (often a failed capacitor or contactor), or low refrigerant from a leak. Make sure the thermostat is on COOL with the fan on AUTO, and check the filter. If the outdoor fan isn’t spinning, turn the system off and call us. Adding refrigerant without finding the leak only buys time, so we find the leak first.

• AC won’t turn on

  Nothing happens at the thermostat, or the indoor unit runs and the outdoor unit stays quiet. It can be thermostat power or settings, a tripped breaker or outdoor disconnect, a float switch that shut the system off because the drain backed up, or a failed capacitor or control board. Check the thermostat’s batteries and mode. If a breaker has tripped, read the breaker note below before you reset it.

• Frozen coil or ice on the refrigerant line

  Ice on the indoor coil or the copper line outside almost always means restricted airflow (a dirty filter, a weak blower, closed vents) or low refrigerant. Turn cooling off, run the fan to thaw it, and replace the filter if it’s dirty. Don’t chip at the ice. If it freezes again, call us.

• Water leaking around the indoor unit

  Most leaks come from a clogged condensate drain, a cracked drain pan, a missing or failed float switch, or a frozen coil melting. If water is pooling or reaching a ceiling or floor, shut the system off and call us. More in how to prevent a clogged AC drain.

• Short cycling

  The system turns on and shuts off every few minutes. That can be a system that’s too big for the house, an airflow restriction, low refrigerant, a thermostat in the wrong spot, or electrical parts on their way out. We find which one before replacing anything.

• Noisy outdoor unit

  Buzzing or humming often means a capacitor, contactor or motor struggling to start. Grinding or squealing points to worn fan motor bearings. Rattling is usually a loose panel or debris. If it’s grinding or you see smoke, shut it off and call us.

• Breaker keeps tripping

  Reset the breaker once. If it trips again, leave it off and call us. Repeated trips point to a shorted part, a failing motor, or a compressor pulling too much current, and resetting it over and over can make the damage worse.

Repair or replace? How we help you decide

Most AC problems come down to one part, and a repair makes sense. Sometimes it doesn’t. Here’s what we weigh with you:

• The age and condition of the system
• Whether the failure is a small part (a capacitor, contactor or drain) or a major one (the compressor or a coil)
• A refrigerant leak that keeps coming back
• How many repairs the system has needed lately
• Comfort problems a repair won’t fix, like rooms that never cool down

If a repair is a bad bet on older equipment, we tell you so. When replacement makes more sense, here’s how we plan a system replacement.
