It's 95°F in Stamford, and your AC just stopped working. Before you panic, here's what to check and how to get help fast.
5 Things to Check Before Calling for Repair
About 20% of emergency AC calls we respond to in Fairfield County turn out to be simple fixes the homeowner could have handled. Save yourself a service call fee by checking these first:
- Check your thermostat. Is it set to "Cool"? Is the temperature set below the current room temperature? Try setting it 5 degrees lower. If you have a programmable thermostat, check the schedule — it may have switched to a different setting.
- Check the circuit breaker. Go to your electrical panel and look for the AC breaker. If it's tripped, flip it off fully, wait 30 seconds, and flip it back on. If it trips again immediately, do not keep resetting it — call a professional.
- Check the air filter. A severely clogged filter can cause the evaporator coil to freeze, shutting down the system. If the filter is dirty, replace it, then wait 2–3 hours for the coil to thaw before restarting.
- Check the outdoor unit. Go outside and look at the condenser. Is the fan spinning? Is the unit making any sound? If it's silent and not running, the issue may be electrical. Also check if vegetation or debris is blocking airflow.
- Check the drain line. Many modern AC systems have a float switch that shuts the system down when the condensate drain is clogged. Look for standing water around your indoor unit. If you see it, the drain line needs clearing.
When to Call for Emergency Repair
Call a professional immediately if:
- The breaker keeps tripping (electrical issue — potential fire risk)
- You smell burning or see smoke near the unit
- The system is making loud grinding, screeching, or banging sounds
- Ice is forming on the refrigerant lines or outdoor unit
- You have elderly family members, infants, or pets who are at risk in the heat
- None of the DIY checks above resolved the issue

Repair vs Replace: How to Decide
Use the "$5,000 rule": multiply the age of your AC (in years) by the repair cost. If the result is over $5,000, replacement usually makes more financial sense.
For example: Your AC is 12 years old and needs a $500 repair. 12 × $500 = $6,000 → consider replacing.
Other signs it's time to replace rather than repair:
- System is 15+ years old
- Uses R-22 refrigerant (phased out, extremely expensive)
- Repair cost is 50% or more of a new system
- You've had 3+ repairs in the last 2 years
How to Stay Cool While Waiting for Repair
- Close blinds and curtains on sun-facing windows
- Use fans to circulate air (ceiling fans, box fans, portable fans)
- Avoid using the oven, dryer, or dishwasher (they generate heat)
- Stay hydrated and move to the lowest level of your home (cooler air sinks)
- If conditions become dangerous (elderly, infants, medical conditions), go to a public library, mall, or neighbor's home
