When your air conditioner breaks down in the middle of a Plano, TX summer, it can feel like a crisis. With temperatures regularly topping 100°F from June through September, a failed AC isn’t just uncomfortable — it can be dangerous, especially for elderly residents, young children, and pets.
At Expedition HVAC, we’ve been responding to emergency AC repairs across Plano and the greater DFW area for over 20 years. Here’s what you should do — and what to expect — when your AC gives out.
Step 1: Don’t Panic — Check the Simple Things First
Before you call anyone, run through these quick checks:
- Check your thermostat — Make sure it’s set to “Cool” and the temperature is set lower than the current room temperature. Check the batteries too.
- Check your circuit breaker — A tripped breaker is one of the most common causes of AC failure. Locate your electrical panel and look for any breakers in the “off” or middle position.
- Check your air filter — A severely clogged filter can cause your AC to freeze up and stop working. A disposable filter should be replaced every 1–3 months.
- Check the condensate drain line — If your AC shuts off but the unit looks fine, the condensate drain may be clogged, triggering a safety shutoff.
Step 2: Know the Warning Signs Before Total Failure
Most AC units don’t fail without warning. Watch for these signs that a breakdown is coming:
- Warm air blowing from the vents even when the system is running
- Weak airflow from registers
- Strange noises — clicking, banging, grinding, or squealing
- Ice forming on the outdoor unit or refrigerant lines
- Unusually high electric bills with no change in usage habits
- Humidity buildup indoors — your AC helps control moisture, and if it’s struggling, you’ll feel it
Step 3: Keep Your Home Safe While You Wait for Repairs
While waiting for your HVAC technician, here are some ways to stay safe in the Plano summer heat:
- Close blinds and curtains on south and west-facing windows to block solar heat gain
- Run ceiling fans counterclockwise in summer to create a cooling effect
- Avoid using the oven — cook on the stovetop, grill outside, or order in
- Stay hydrated and check on elderly neighbors
- Consider a local cooling center if your home becomes dangerously hot
Common AC Repairs in Plano, TX
Our technicians handle hundreds of AC repair calls across Plano every summer. Here are the repairs we see most often:
- Refrigerant recharge — Low refrigerant (Freon or R-410A) causes weak cooling and is often a sign of a leak
- Capacitor replacement — Capacitors start and run your AC motors. They fail frequently in the Texas heat
- Contactor replacement — The contactor controls power to your compressor and fan motor
- Compressor issues — The compressor is the heart of your AC. Failures are serious but often diagnosable
- Frozen evaporator coil — Usually caused by restricted airflow or low refrigerant
- Clogged drain line — Causes water damage and system shutdowns
Repair or Replace? How to Decide
Use this simple rule of thumb: multiply the age of your system (in years) by the repair cost. If the result exceeds $5,000, replacement is usually the better investment. For example:
- 10-year-old system + $600 repair = $6,000 → Consider replacement
- 5-year-old system + $600 repair = $3,000 → Repair makes sense
Our technicians will always give you an honest assessment. Because our team is paid salary — not commission — we have no incentive to recommend a replacement when a repair will do.
