Emergency AC Repair: What to Do When Your AC Dies

What to Do When Your AC Stops Working in Austin

Your AC just quit. The house is getting warmer by the minute, and outside it is 100 degrees in Central Texas. Before you panic, before you start Googling "emergency AC repair Austin" on your phone while sweating through your shirt, take a breath. There are a few things you can do right now to protect your home, your family, and your HVAC system.

At CG Service Pros, we handle emergency AC calls across Austin and the surrounding areas every summer. Most homeowners do not know the difference between an inconvenience and a true emergency, and that confusion often leads to bad decisions, unnecessary costs, or worse, waiting too long when something dangerous is happening.

This guide walks you through exactly what to do when your AC dies, what counts as a real emergency, basic troubleshooting you can try yourself, and when it is time to call a professional.

What Qualifies as a True AC Emergency

Not every AC problem is an emergency. A system that is running but not cooling as well as usual can probably wait until the next business day. But certain situations require immediate attention.

Health and Safety Risks

• Extreme heat with no cooling. When outdoor temperatures exceed 95 degrees and you have no air conditioning at all, this becomes a health concern. Heat exhaustion and heat stroke are real risks, especially for elderly family members, young children, and pets. Austin regularly hits 100 to 110 degrees from June through September.
• Burning or electrical smells. If your system smells like it is burning or you notice a strong chemical odor, shut it off at the breaker immediately. This could indicate an electrical short, overheating motor, or melting wires, all of which are fire hazards.
• Sparks or tripped breakers. If your AC keeps tripping the circuit breaker or you see sparks near the indoor or outdoor unit, stop trying to restart it. Repeated breaker trips mean something is drawing too much power, and forcing it back on can cause a fire or destroy the compressor.
• Water flooding. A small amount of condensation near your indoor unit is normal. Water pouring across your floor is not. A clogged drain line or frozen evaporator coil can cause significant water damage to your home if not addressed quickly.

Situations That Can Wait

• The AC is running but the house is a few degrees warmer than the thermostat setting
• Unusual noises that come and go, with the system still cooling
• A gradual decline in cooling performance over several days
• One room is warmer than others

If your situation falls in the "can wait" category, you should still schedule a service call soon, but it does not require emergency after-hours pricing.

Immediate Steps When Your AC Fails

Before you call anyone, run through these steps. They take about 10 minutes, and in some cases they will solve the problem entirely.

Step 1: Check Your Thermostat

This sounds obvious, but it catches more homeowners than you would expect. Verify that your thermostat is:

• Set to "cool" mode (not "heat" or "off")
• Set at least 3 degrees below the current room temperature
• Set to "auto" for the fan, not "on" (the "on" setting runs the fan continuously without cooling)
• Displaying properly, with no blank screen or error codes

If your thermostat screen is blank, replace the batteries. If it uses hardwired power, check the breaker. A dead thermostat means no signal to your system.

Step 2: Check the Circuit Breakers

Your HVAC system typically uses two breakers: one for the indoor air handler and one for the outdoor condenser. Head to your electrical panel and look for any tripped breakers. If you find one, flip it fully off, then back on.

Step 3: Check the Air Filter

A severely clogged air filter can cause your system to freeze up and stop cooling entirely. Pull out the filter and look at it. If you cannot see light through it, it is too dirty. Replace it or remove it temporarily to allow airflow while you troubleshoot.

In Austin, where pollen, dust, and pet dander are constant challenges, filters should be changed every 30 to 60 days during heavy use months.

Step 4: Check the Outdoor Unit

Go outside and look at your condenser unit. Check for:

• Debris. Leaves, grass clippings, or other material blocking the fins
• Ice. Frost or ice on the refrigerant lines or the unit itself, which indicates a refrigerant leak or airflow problem
• The fan. Is the outdoor fan spinning? If not, the unit may have a bad capacitor or fan motor
• Standing water. Normal condensation drains away. Pooling water around the base could indicate a drainage issue

If everything looks normal but the fan is not running, you likely have a capacitor or contactor issue. This requires a technician.

Step 5: Keep Your Home Cool While You Wait

If you have confirmed that your AC needs professional help, take these steps to keep your home as comfortable as possible:

• Close all blinds and curtains, especially on south and west facing windows
• Turn on ceiling fans and any portable fans you have
• Close doors to rooms you are not using to concentrate cooling in a smaller space
• Avoid using the oven, stove, or dryer, which all add heat to your home
• Stay hydrated, especially children and elderly family members
• If temperatures inside exceed 90 degrees and you have vulnerable family members, consider relocating temporarily

Common Causes of Sudden AC Failure in Austin

Understanding what caused the failure helps you communicate with your technician and sets realistic expectations for the repair.

Capacitor Failure

The most common cause of sudden AC failure in Central Texas. Capacitors store and release electrical energy to start and run the compressor and fan motors. Austin's extreme heat puts tremendous stress on capacitors, and they frequently fail during the hottest part of summer. A bad capacitor usually means the outdoor unit hums but the fan does not spin.

Typical repair cost: $150 to $400 including parts and labor.

Refrigerant Leak

If your system has been gradually cooling less effectively and then stops entirely, a refrigerant leak is likely. Refrigerant does not "run out" under normal circumstances. If levels are low, there is a leak somewhere that needs to be found and repaired before recharging.

Typical repair cost: $200 to $1,500 depending on the location and severity of the leak.

Compressor Failure

The compressor is the heart of your AC system. When it fails, the system cannot cool at all. Compressor failures are often caused by running the system with low refrigerant, electrical issues, or simply age. This is the most expensive component to replace.

Typical repair cost: $1,500 to $3,000. At this price point, you should discuss with your technician whether replacement makes more sense than repair, especially if your system is over 10 years old.

Frozen Evaporator Coil

Restricted airflow from a dirty filter, closed vents, or low refrigerant can cause the evaporator coil to freeze solid. When this happens, the system cannot absorb heat from your home's air. You may notice ice on the refrigerant lines or water around the indoor unit as the ice melts.

What to do: Turn the system to "fan only" for 2 to 4 hours to let the ice melt. If it freezes again after restarting, you have an underlying issue that requires professional diagnosis.

Electrical Issues

Wiring problems, contactor failure, or control board malfunctions can all cause sudden shutdowns. These are especially common in older Austin homes with aging electrical systems. If your AC is cycling on and off rapidly (called short cycling), an electrical issue is usually the cause.

How Emergency AC Repair Pricing Works

Emergency or after-hours service typically costs more than a standard service call. Here is what to expect in the Austin market.

• Standard service call (business hours): $75 to $150 trip charge, plus parts and labor
• After-hours or weekend service: $150 to $250 trip charge, plus parts and labor at standard rates
• Holiday service: Up to $300 trip charge

The trip charge gets the technician to your door. Parts and labor for the actual repair are on top of that. Some companies waive the trip charge if you proceed with the repair.

How to Choose an Emergency AC Repair Company

When your AC fails and you need help fast, it is tempting to call the first company that pops up on Google. Take five minutes to vet them first.

What to Look For

• Licensed and insured. In Texas, HVAC contractors must hold a TDLR (Texas Department of Licensing and Regulation) license. Ask for the license number.
• Transparent pricing. A reputable company will give you a trip charge upfront and provide a written estimate before starting any work.
• Reviews. Check Google reviews. Look for recent reviews that mention emergency or after-hours service specifically.
• Warranty on work. Any quality repair should come with a warranty on both parts and labor.
• No pressure to replace. Be cautious of any technician who immediately recommends a full system replacement without thoroughly diagnosing the problem first.

Red Flags

• Refusing to provide a written estimate
• Quoting a "flat rate" repair without diagnosing the problem
• Pressuring you to replace the entire system on an emergency call
• Unable to provide a license number
• Demanding full payment before starting work

Preventing Emergency AC Breakdowns

The best emergency is the one that never happens. Most sudden AC failures in Austin are preventable with regular maintenance.

Schedule Seasonal Tune-Ups

A professional HVAC tune-up in early spring catches worn capacitors, low refrigerant, dirty coils, and electrical issues before they cause a failure during peak heat. Think of it as preventive medicine for your AC system.

Change Filters Regularly

In Austin's dusty, pollen-heavy environment, plan on changing your filter every 30 to 60 days during the cooling season (April through October). Set a recurring reminder on your phone.

Keep the Outdoor Unit Clear

Maintain at least 2 feet of clearance around your outdoor condenser. Trim back bushes, remove leaves and debris, and rinse the fins with a garden hose a couple of times per season.

Address Small Problems Early

That unusual noise or slight decrease in cooling performance is your system telling you something is wrong. Fixing a $200 problem now prevents a $2,000 emergency later.

Consider a Maintenance Plan

A maintenance plan with a trusted HVAC company gives you priority scheduling, regular inspections, and discounted repairs. When everyone else is waiting 3 days for a technician in the middle of July, maintenance plan members get bumped to the front of the line.

Frequently Asked Questions

How long can I safely go without AC in Austin during summer?

For healthy adults, a day or two without AC is uncomfortable but not dangerous. For elderly family members, children under 5, people with heart conditions, and pets, the risk of heat-related illness increases significantly once indoor temperatures exceed 90 degrees. If your home reaches that point and you cannot get same-day repair, relocate vulnerable family members.

Should I try to fix my AC myself before calling a professional?

You can and should try basic troubleshooting: checking the thermostat, resetting breakers, replacing the air filter, and clearing debris from the outdoor unit. Do not attempt anything involving electrical components, refrigerant, or opening up the unit. AC systems run on high voltage, and refrigerant handling requires an EPA certification.

Is it worth paying for emergency after-hours AC repair?

It depends on the situation. If temperatures inside your home are dangerous and you have vulnerable family members, yes. If the AC stopped at 8 PM and overnight temperatures will drop into the 70s, you can usually wait until morning and save the after-hours surcharge. The temperature forecast is your best guide.

How do I know if I should repair or replace my AC?

If your system is under 10 years old and the repair costs less than half the price of a new system, repair is usually the right call. If it is over 15 years old, uses R-22 refrigerant (which is being phased out), or the repair exceeds $3,000, replacement makes more financial sense. We break this down in detail in our AC repair vs. replacement guide.

What information should I have ready when I call for emergency AC repair?

Have the following ready: your system's make and model (found on the data plate on the outdoor unit), the age of the system, a description of what happened (did it stop suddenly or gradually), any error codes on your thermostat, and whether you have tried any troubleshooting steps. This helps the technician prepare and can speed up the repair.
