An HVAC emergency occurs when an issue with your heating and cooling system threatens your safety. Examples include a system breakdown during extreme temperatures, foul odors, or an electrical issue. If you’re worried about your system's performance and wondering whether it’s urgent, this guide from Brothers will help you determine what’s considered an HVAC emergency and what’s not.

If you think you have an emergency, don’t delay. Schedule emergency service now!


WHAT’S CONSIDERED AN HVAC EMERGENCY?

What’s the difference between regular and emergency HVAC services? Your safety is always the deciding factor. Old age, damage, and lack of maintenance are among the usual culprits behind an emergency. If you fit even one of these scenarios, it’s time to call for professional help.


UNSAFE INDOOR TEMPERATURES

North Carolina is a hot and humid state, and temperatures can reach 100 degrees Fahrenheit in the middle of summer. If your cooling system isn’t working, you could face dehydration or heatstroke. Elderly adults, adults with chronic conditions (like heart disease), and young children are at higher risk for heat stroke.


ACTIVE LEAKS

What’s considered an HVAC emergency when it comes to leaks? All of them, as you should never see a leak coming from your HVAC system. While some leaks are minor and may stem from a clogged drain pan, others can pose a safety threat.

Examples include a refrigerant or oil leak. Refrigerant and oil are flammable under the right conditions, and an oil leak can cause widespread damage wherever it goes.


FOUL ODORS

You should never smell burning, chemical, or rotten egg odors from your cooling or heating system. These are all serious indicators of a deeper problem that could cause a fire or result in carbon monoxide poisoning. Leave your home immediately if you smell any of these odors. You should also call 911 or call your local gas company.


CARBON MONOXIDE ALARM GOES OFF

If your carbon monoxide detector goes off, whether it’s due to your HVAC or not, you need to evacuate the home and call 911. Carbon monoxide has no odor, yet it is extremely hazardous. Signs of carbon monoxide poisoning include dizziness, headaches, and difficulty breathing.


YOU SENSE IMMEDIATE DANGER

When in doubt, bring in an HVAC professional. If your heating and cooling system is acting strangely, calling a technician will always be your best bet.

Carbon monoxide alarm goes off

Emergency

Evacuate immediately and call 911. Do not stay inside to troubleshoot the HVAC system.

Active leaking around HVAC equipment

Usually an emergency

Turn the system off if safe to do so and schedule service before damage gets worse.

Uneven room temperatures

Usually not an emergency

Schedule normal service unless the temperature becomes unsafe for your household.

Slightly weak airflow

Usually not an emergency

Check the filter and vents first. If the issue continues, schedule a regular HVAC appointment.

HVAC failure during mild weather

Usually not an emergency

Book service soon. It may not require an emergency unless your safety, health, or property is at risk.

Give us a call if you suspect any of these issues in your home, and we’ll send a knowledgeable technician to address them as soon as possible. Your air conditioning and heating system has many working parts that can experience issues, often seemingly out of nowhere.


HEALTH AND PROPERTY RISKS TO BE TREATED AS EMERGENCIES

There are a few more specific situations that you should consider as HVAC emergencies.


NO HEAT DURING COLD NIGHTS

North Carolina may not get the heavy snow seen in other states, but it can still get extremely chilly during storms, with sleet and moderate snowfall occurring a few times per year. A no-heat situation on a freezing night can put families at risk and cause frozen pipes.


REPEATED HVAC FAILURE

Ongoing HVAC failure is a major issue for homeowners and landlords. Both pose serious risks, as they likely won’t provide heating or cooling in extreme temperatures. Repeated failures can also make it difficult to attract tenants if you’re renting out your place.

3 MECHANICAL WARNING SIGNS YOU SHOULDN’T IGNORE

What’s considered an HVAC emergency that people often overlook? The following issues may not seem like a big deal, but they can increase the risk of mechanical failures.


1. SQUEALING SOUNDS

When your HVAC system is struggling, you may hear screeching or squealing sounds. These noises usually indicate internal components, such as motor bearings, coming loose and rubbing together.


2. GRINDING AND BANGING SOUNDS

These sounds likely mean a fan motor is on its way out. This issue might occur when your motor’s bearings start to come loose due to a lack of lubrication or age.


3. FROZEN OUTDOOR UNIT

In some cases, icy build-up can form on your outdoor unit during fall or winter. However, clogged condenser coils or dirty filters can block airflow, which leads to frost.

All of these issues can lead to complete system failure. Brothers offers emergency HVAC repair to fix problems and get your heating and cooling system working right away.


WHEN SHOULD I PUT MY HVAC IN EMERGENCY MODE?

Use the system’s emergency mode in freezing temperatures if you have no other way to stay warm. This mode mainly applies to heat pumps when the main unit isn’t working or can’t keep up in extreme conditions.


HOW LONG CAN YOU BE WITHOUT HEAT IN NORTH CAROLINA?

Various factors impact how long you can go without heat. These include indoor temperatures, household health risks, and overnight lows. In NC and SC, mild winter days are usually manageable, even without a functional HVAC system. However, freezing nights in the middle of winter can quickly create urgent situations, especially for vulnerable people like the elderly or children.


AT WHAT TEMPERATURE WILL PIPES FREEZE?

Pipes can freeze when temperatures fall below freezing, with the highest risk at or below 20 degrees Fahrenheit for several hours. Frozen pipes can result in restricted water flow, leaks, and backed-up drains.


HOW MUCH DOES EMERGENCY HVAC COST?

That depends on what needs to be done. We’re proud to offer transparent pricing, personalized quotes, discounts, and financing options to help you manage the costs. You will always receive a free quote before we start any work.


ARE EMERGENCY HVAC REPAIRS WORTH THE COST?

Yes, emergency HVAC repairs are always worth it. A damaged HVAC system can put your family at risk or expose you to a hazard, so it’s better to get it fixed rather than wait for the situation to get worse.


WHAT ISN’T AN HVAC EMERGENCY?

Now that you know what’s considered an HVAC emergency, it’s time to narrow down what isn’t. The following issues are frustrating but manageable with a fan for support or extra blankets until you can schedule service during normal business hours.

  • Uneven room temperatures

  • Slightly reduced airflow

  • Dirty filter

  • Minor thermostat issues

  • HVAC failure during mild weather

  • Neighborhood power outage


WHEN YOU SHOULD CALL AN HVAC CONTRACTOR
