What Qualifies as an HVAC Emergency?

When your heating or cooling system stops working, a prompt response can protect your home and health. Below are examples of HVAC emergencies we respond to with 24/7 service:

Water Leaks Near Your HVAC System
Shut down the system and call for help if you notice active leaking or signs of water damage.
Suspected Gas Leak
If you smell gas, evacuate and contact the fire department. Once safe, contact Logan Services if the leak may be HVAC-related.
Carbon Monoxide or Smoke Alarm Activation
Exit the home and call 911 if alarms are sounding. Open windows and turn off your HVAC system only if it’s safe. Call us if a furnace or system issue is suspected.
No Heat or No Cooling
If your HVAC system stops working entirely, especially during extreme temperatures, this qualifies as an emergency. Call us for immediate repair.
Operational Issues Within Warranty
If your system was installed by Logan Services within the past year and you’re experiencing a malfunction, we provide 24/7 warranty support.

What to Expect During Emergency Service

When you schedule emergency HVAC service with Logan Services, you can expect fast communication, expert troubleshooting, and respectful in-home service. During your call, our customer service team will assess your situation, confirm technician availability, and provide an estimated arrival window. When the technician arrives, they will conduct a thorough on-site diagnosis to identify the problem and clearly explain your repair or replacement options. If an immediate fix isn’t possible, we may provide a temporary solution or stabilize the system until a full repair can be completed. We also strive to offer free, same-day estimates and financing guidance to help manage unexpected costs. Throughout the visit, our team uses protective gear and maintains a clean workspace, ensuring your home is treated with care.

You’ll receive knowledgeable service, clear communication, and reliable support every step of the way—because your comfort and safety are always our top priority.

What to Do When Demand is High

If we’re at full capacity and unable to dispatch a technician immediately, it’s likely that other providers are experiencing similar demand. In the meantime, you can take safe, proactive steps to troubleshoot the issue and maintain comfort until professional help becomes available:

Check and Replace the Air Filter
A clogged or dirty filter can restrict airflow and cause cooling issues. Make sure your system has a fresh filter installed.
Perform a Hard Reset of Your HVAC System
Turn off the breakers for both your furnace and air conditioner. Leave them off for 3–5 minutes, then restore power. This can reset system controls and resolve minor faults.
Inspect for Ice Buildup
If you see ice on your indoor or outdoor units, turn off cooling mode immediately. Keep the fan setting on to help circulate air and speed thawing. We cannot perform a proper diagnosis until the system is fully thawed.
Use Fans for Air Circulation
Running the fan (without cooling mode) can help maintain airflow throughout your home until service is available.
Monitor Indoor Temperature Gaps
Smaller temperature differences between your thermostat setting and indoor conditions may be normal, especially during extreme outdoor heat.
Call for Status Updates
Our team can provide wait time estimates and notify you if an earlier appointment becomes available.

Emergency HVAC Financing Options Available

Unexpected HVAC breakdowns can put stress on your household finances, especially when repairs or replacements are urgent. Logan Services offers flexible financing options to help you manage these costs without delay. Our plans include low monthly payments, deferred interest options, and quick approval processes through trusted lending partners. Whether you need emergency repairs or a full system replacement, our financing solutions are designed to fit your budget and restore comfort quickly.

Preventing Future HVAC Emergencies

Avoiding emergency HVAC situations often comes down to being proactive rather than reactive. Consistent upkeep and seasonal attention to your system’s condition can significantly reduce your risk of costly breakdowns. Start with regular filter changes every 1–3 months to maintain proper airflow and system performance. Book seasonal tune-ups to catch small issues—like worn components or refrigerant imbalances—before they turn into bigger problems. Verify that your thermostat is properly programmed and functional year-round. Watch for ice buildup or water leaks and shut off your system if they appear to prevent further damage. Knowing how and when to perform a breaker reset can also help restore functionality without needing a service call. And remember, even a high-quality system has limits—being aware of weather-related strain can help set realistic expectations.

For year-round peace of mind, consider enrolling in a Logan Services HVAC maintenance plan. Our plans include routine inspections, priority scheduling, and exclusive discounts, helping you avoid costly surprises and extend the life of your system. With these habits in place, you’ll extend system lifespan, avoid mid-season failures, and keep your comfort uninterrupted.

HVAC Emergency Frequently Asked Questions

What Qualifies as an HVAC Emergency?

Any situation involving no heating or cooling, active leaks, smoke or carbon monoxide alarms, or suspected gas leaks can be considered an HVAC emergency.

Can I Do Anything Before a Technician Arrives?

Yes. You can check your air filter, reset the system at the breaker, and turn off cooling mode if ice is present on your unit.

Why Do I Need to Turn Off the AC If There's Ice?

Running your air conditioner while ice is present can worsen the issue and damage the system. Turning it off allows the ice to thaw so a technician can inspect the unit and identify the root cause without obstruction.

Is It Normal for My HVAC System to Struggle in Extreme Heat?

Yes. During high outdoor temperatures, your system may not achieve large temperature drops. This is expected behavior and not always a sign of failure.

What If I Smell Gas or Suspect a Carbon Monoxide Issue?

Leave the home immediately and call 911. Once safe, notify Logan Services if the source may be related to the HVAC system.
