Texas Summer AC Tips

It's 105°F outside. Your AC is working overtime.

Here's how to survive without a $500 electric bill.

Before Summer Hits

March/April:

  • Schedule tune-up (before rush)

  • Change filter

  • Clear debris around outdoor unit

  • Check thermostat batteries


Doing this early = shorter wait times, better prices.

During Peak Summer

Daily habits:

  • Set to 78°F when home

  • 85°F when away (don't turn off completely)

  • Use ceiling fans (feels 4° cooler)

  • Close blinds on sunny windows


Weekly:
  • Check filter (change if dirty)

  • Ensure vents aren't blocked

  • Listen for unusual sounds


Monthly:
  • Hose down outdoor unit (gently)

  • Check drain line for clogs

  • Verify thermostat accuracy


Efficiency Tricks

Programmable thermostat:
Raise temp automatically when you're at work. Save 10-15%.

Seal leaks:
Check doors, windows, ductwork. Cool air escaping = money wasted.

Shade the outdoor unit:
But don't block airflow. Shade can improve efficiency 10%.

Run appliances at night:
Oven, dryer, dishwasher generate heat. Run after 8pm.

When to Call a Pro

Warning signs:

  • Not cooling to set temperature

  • Ice on coils or refrigerant lines

  • Strange smells (musty, burning)

  • Unusual noises (grinding, squealing)

  • Water pooling around indoor unit

  • Electric bill spike without usage change


Don't wait. Small problems become expensive replacements.

Texas-Specific Challenges

Extreme runtime:
Units run 10+ hours daily. More wear than northern climates.

Hard water:
Affects efficiency. Consider water treatment.

Dust/pollen:
Clogs filters faster. Change more frequently.

Power grid stress:
ERCOT peak times (2-7pm). Raising temp helps the grid and saves money.

Dirty filter (reduced life)$0 filter vs $5,000 compressor

Delayed repair$300 fix vs $8,000 replacement

Maintenance is always cheaper than replacement.
