Check These Steps Before Calling for Emergency Repairs

Before assuming the worst, troubleshoot common HVAC issues for a few minutes. Some problems have simple solutions that can save time and money without a service call.

• Make Sure the Thermostat is Set Correctly

Your thermostat is the brain of your HVAC system, and a simple setting adjustment might fix the issue.

If the heat isn’t working, ensure it’s set to “heat” and that the temperature is higher than the current room temperature.

If the air conditioner isn’t cooling, set the thermostat to “cool” and check that it’s lower than the room temperature.

If the system doesn’t respond, the thermostat batteries may be dead. Try replacing them and restarting the system.

• Check the Power Supply

A tripped breaker or blown fuse can shut down your heating and cooling system. Go to the electrical panel and check if any breakers have flipped. If you find one, reset it and see if the system turns back on.

If the breaker trips again immediately, do not reset it. This could indicate an electrical issue that requires professional attention.

• Inspect the Air Filter

A dirty or clogged air filter can restrict airflow and cause the system to shut down as a safety precaution. If it has been more than 30 to 60 days since the last filter change, replace it and try running the system again.

Look for Ice or Blockages on the Outdoor Unit

If the air conditioner isn’t working, check the outdoor condenser unit. Leaves, dirt, or ice buildup can prevent it from functioning properly. If ice is present, turn off the system and let it thaw before restarting.

• Listen for Unusual Noises

Strange sounds coming from the system may indicate loose components, motor issues, or airflow problems. If you hear banging, screeching, or rattling, turn off the unit and call for professional repair.

If none of these steps restore function to the system, it’s time to call for emergency HVAC repair.

When to Call for Emergency HVAC Repairs

Some HVAC issues require immediate service to protect your home, your health, or your system from further damage. Here are the most urgent situations where calling a professional is necessary.

No Heat in Cold Weather

If the heating system stops working in freezing temperatures, it can lead to burst pipes, increased humidity, and dangerous indoor conditions. A furnace or heat pump that won’t turn on should be repaired as soon as possible.

No Air Conditioning in Extreme Heat

During a heatwave, indoor temperatures can rise dangerously fast, especially in homes with children, elderly residents, or pets. If the air conditioner stops cooling, emergency service is necessary to restore a safe and comfortable environment.

Burning Smells or Gas Odors

A burning smell from an HVAC system could mean overheating components or electrical wiring problems. If the odor is strong or persistent, turn the system off immediately and call for service.

A rotten egg smell could indicate a gas leak. If this happens, leave the house immediately and contact the gas company before calling an HVAC technician.

Unusual Sounds

Loud banging, grinding, or screeching noises often signal serious mechanical issues, such as a failing motor, loose parts, or compressor failure. Running the system in this condition can cause further damage, so turning it off and scheduling a repair is the best course of action.

Water or Refrigerant Leaks

Water pooling around the indoor unit could be due to a clogged condensate drain, frozen evaporator coils, or a cracked drain pan. Refrigerant leaks, which may cause hissing sounds or reduced cooling performance, should also be addressed immediately, as they can pose health and environmental risks.

What to Expect from an Emergency HVAC Repair Service

Knowing what to expect when calling for emergency service can help you feel more prepared.

• Immediate Response
  • A professional technician will respond as quickly as possible and assess the situation over the phone to determine the urgency of the repair.
• On-Site Diagnosis
  • Once on-site, the technician will inspect the system, identify the problem, and provide a clear explanation of the issue and potential solutions.
• Efficient Repairs
  • Most emergency repairs can be completed on the same visit, as technicians carry common replacement parts. If a major repair is needed, options for temporary solutions or expedited ordering of necessary components will be discussed.
• Transparent Pricing
  • Reliable HVAC professionals will provide upfront pricing before proceeding with any repairs, ensuring no hidden fees or surprises.

How to Prevent HVAC Emergencies

While some breakdowns happen unexpectedly, regular maintenance and preventative care can significantly reduce the likelihood of sudden failures.

• Schedule Routine Maintenance: A seasonal HVAC tune-up ensures that all components are working properly, helping identify minor problems before they become major repairs.
• Change Air Filters Regularly: Keeping filters clean improves airflow, reduces strain on the system, and prevents overheating or freezing of components.
• Monitor Energy Bills: A sudden increase in energy usage without a change in routine can signal inefficiencies or mechanical issues that should be checked by a technician.
• Listen for Warning Signs: Unusual noises, inconsistent temperatures, or frequent cycling on and off often indicate that the system needs professional attention. Addressing these issues early prevents unexpected breakdowns.
