What Is an AC Emergency?
An AC emergency is any sudden failure that compromises your comfort or safety, especially during extreme heat. AC emergencies could be:
- A complete system shutdown on a hot day
- Warm air blowing from vents despite a running unit
- Strange burning smells
- Loud, grinding noises
These are signs that your system may be on the verge of a more serious failure — or that it’s unsafe to operate.
If you have an AC emergency, turn off your system and call Service Today right away. We’re available 24/7 to respond to urgent repair needs, helping you restore comfort and peace of mind as quickly as possible.
Signs You Need Air Conditioning Repair vs. Replacement
It’s important to act quickly and request a service when you recognize any of these signs of needed air conditioning repair:
- Warm air: Your AC should always be a source of cool air. If you notice warm air blowing from your vents, your outdoor unit’s fan may need repair or replacement.
- Short-cycling: When your system frequently turns on and off, this is known as short-cycling, which puts a strain on your system and drives up your energy bills.
- Ice on the unit: If you see ice forming around your unit, you could have frozen evaporator coils. Replacing a dirty air filter may resolve the issue, or you could have leaking or low refrigerant.
- Strange odors: Air conditioners shouldn’t produce any strong odors during operation. Exhaust and burning smells often point to an issue with electrical components, while musty smells could mean mold.
- Poor airflow: Insufficient circulation can point to several issues, including a clogged air filter or a system that’s improperly sized for your home.
Common Causes of AC Breakdowns
Air conditioning units can break down for several reasons. Some of the most common include:
- A dirty air filter: In most cases, you can change these yourself. Replace them at least every three months. Otherwise, your AC can overheat and shut off.
- Thermostat problems: The thermostat controls when your AC turns on and off. When the thermostat malfunctions, your air conditioner does too.
- Evaporator coil problems: The coil absorbs heat to send cool air into the house. Debris on the coil can cause it to malfunction.
- Condenser coil problems: This coil can also have built-up dirt and debris interfering with optimal performance, resulting in higher energy costs.
- Leaking refrigerant: Refrigerant is an essential part of the AC system. If refrigerant leaks, the unit won’t cool effectively.
- System age: If your air conditioner is over 10 years old and breaks down frequently, we may recommend AC replacement instead of repair.
You should schedule annual air conditioning maintenance to reduce the risk of breakdowns and frequent repairs.

Frequently Asked Questions
Why is my AC making loud noises?
There can be multiple reasons for loud AC noises:
- Loud buzzing noises are likely the result of loose parts.
- Sharp shrieking sounds can be caused by leaking refrigerant.
- Clunking or banging noises may indicate a broken part.
Why does my AC smell bad?
Bad odors coming from your AC may be caused by:
- Musty odors: Mold and mildew
- Dirty sock odors: Dirty evaporator coils
- Burning odors: Overheating parts or electrical failure
How do you troubleshoot your AC?
If your AC is malfunctioning, you can troubleshoot it in several ways:
- Check the thermostat to ensure it’s set properly, with the fan on Auto and set to Cool.
- Check the electrical panel to see whether the AC unit has a tripped circuit breaker.
- Check and change your air filter.
How can I tell if my AC issue is serious or just a minor problem?
Even if the issue seems minor, it’s best to schedule a diagnostic. If your AC is making unusual sounds, blowing warm air, cycling frequently, or causing sudden spikes in your energy bills, call a professional.
Can running my AC with a known issue cause more damage?
Yes. Operating your air conditioner while it’s malfunctioning can strain other components and lead to more extensive and expensive damage. Always shut it down and call a professional if something seems off.
How much does AC repair usually cost?
Repair costs can vary depending on the issue, but Service Today offers upfront, flat-rate pricing with no surprises. We also provide estimates before any work begins so you can make an informed decision.
