When your HVAC system isn’t working as it should (especially during the colder months in Northern Michigan) it’s easy to panic. But not every issue is an emergency. Knowing the difference can save you stress, money, and even keep your family safe. Here’s a guide to help you identify what’s urgent, what’s not, and how Mammoth Mechanical can assist every step of the way.
What Counts as an HVAC Emergency?
Some situations need immediate attention, especially during Northern Michigan’s harsh winters. If you experience any of these, it’s time to call for emergency HVAC service:
Your Furnace Completely Breaks Down in Winter
When the temperature outside drops, a non-functioning furnace isn’t just uncomfortable– it can quickly escalate into a serious problem. Without heat, your home’s temperature may fall to unsafe levels, leading to frozen or burst pipes, and even putting your family’s health at risk.
What to Do: Ensure your thermostat is set to “heat” and the temperature is higher than the current room temperature. Replace the batteries if necessary. Sometimes a tripped breaker can cut power to the furnace. Reset it if needed.
If these quick checks don’t solve the issue, don’t wait. Contact an HVAC professional right away for emergency repairs to restore your heat. While waiting for assistance:
- Use space heaters safely to maintain some warmth.
- Bundle up with blankets and close off unused rooms to conserve heat.
- Never use an oven or grill for heating, as it’s dangerous.
You Smell Gas or Burning Odors
A gas leak smells like rotten eggs and requires immediate action to prevent a life-threatening situation. Burning odors might mean the system is overheating, components are melting, or there’s a wiring issue– all of which pose serious safety risks.
What to Do: Turn off the furnace using the shut-off switch located near the unit. If you suspect a gas leak, don’t risk staying inside. Leave the house immediately and avoid turning on lights or using electronic devices, as they could ignite the gas.
- For a gas leak: Contact your gas company or 911 to report the issue.
- For burning smells: Contact Mammoth Mechanical or another trusted HVAC professional for an urgent inspection.
Your Carbon Monoxide Detector Goes Off
Carbon monoxide (CO) is an odorless, colorless gas that can build up in your home due to a malfunctioning furnace or blocked ventilation. Exposure to CO can be deadly, making this an emergency situation.
What to Do: Shut down your HVAC system, gas water heater, or any other appliances that might produce CO. Immediately get everyone (including pets) out of the house. Contact 911 to report the situation and get guidance.
Once cleared by emergency services, call a local HVAC company to inspect and repair your furnace or ventilation system to prevent future risks.
Unusually Loud Noises From Your System
Strange sounds like banging, squealing, or grinding often indicate a serious mechanical issue. These could stem from a loose or broken component, motor failure, or even debris in the system. Ignoring these sounds can lead to further damage and costly repairs.
What to Do: Continuing to run the system can cause additional damage. Use the shut-off switch or turn off the breaker connected to your HVAC unit. Check for loose parts or debris around the unit, but don’t attempt to repair anything yourself. If possible, record the sound on your phone. This can help professionals identify the problem faster.
Contact Mammoth Mechanical for a thorough inspection and repair. Let us know about the noise you heard and any observations you made to help diagnose the issue quickly.
Non-Emergencies: Heating Issues You Can Handle Alone or Plan to Fix Later
Not every HVAC issue needs immediate attention, but that doesn’t mean you should ignore it. Here are some common heating problems, what might be causing them, and how to resolve or plan for them.
Uneven Heating Between Rooms
What’s Happening:
- Blocked vents or furniture covering registers.
- Dampers (internal HVAC components that direct airflow) may be closed or unbalanced.
- An unbalanced system or inadequate insulation could also contribute.
What to Do: Ensure nothing is blocking vents (like furniture or curtains) and that they’re fully open. Adjust dampers to redirect airflow evenly to problem areas, and close off unused rooms. If the problem persists, our team can balance your system or recommend other fixes.
Higher Heating Bills
What’s Happening: Your system may be running inefficiently due to clogged filters, lack of maintenance, or aging components. Drafts or poor insulation could also make your system work harder.
What to Do: Dirty filters make your system less efficient. We recommend replacing them every 1-3 months during heavy use. Seal drafts with weatherstripping or caulk to keep heat inside.
Regular HVAC maintenance ensures your system runs efficiently. We’ll clean components, check for wear, and make necessary adjustments to optimize performance.
Thermostat Issues
What’s Happening: Dead batteries can prevent the thermostat from communicating with your system. Miscalibration or malfunctioning parts can also cause incorrect readings.
What to Do: Replace the batteries or reset the thermostat. If these steps don’t work, we can inspect and repair or replace your thermostat. For added convenience and efficiency, ask us about installing a programmable or smart thermostat that helps lower energy bills.
Weak Airflow
What’s Happening:
- Often caused by a clogged air filter or obstructions in your ducts.
- Could also indicate a more serious issue, such as a failing blower motor.
What to Do: A dirty filter is the most common culprit. Swap it out and see if the airflow improves. Look for anything blocking your vents, registers, or duct openings. If airflow remains weak, give us a call. We’ll check your ducts, blower motor, and other components to pinpoint the issue.
Proactive Tips to Avoid HVAC Emergencies
A little maintenance goes a long way toward preventing costly breakdowns:
- Schedule Annual Tune-Ups: Regular furnace maintenance can catch small problems before they turn into big ones.
- Replace Air Filters Regularly: Dirty filters strain your system, leading to higher energy bills and potential damage.
- Install Carbon Monoxide Detectors: A must-have for any home with a furnace.
- Address Issues Early: Don’t wait for a minor issue to become an emergency.

HVAC Emergency FAQs
My carbon monoxide detector hasn’t gone off, but I feel lightheaded– what should I do?
If you suspect carbon monoxide exposure, evacuate your home immediately, even if the detector hasn’t alarmed. Call 911 and avoid re-entering your home until emergency services declare it safe. Contact an HVAC professional to inspect your system for leaks or ventilation issues.
Why is my heat pump blowing cold air in the winter?
This could be normal defrost mode, but if it lasts longer than 10 minutes or your home isn’t staying warm, it may indicate a problem with the compressor, refrigerant, or thermostat. While not always an emergency, it’s best to schedule a service call promptly.
Is it safe to run my HVAC system after a minor flood?
No, even minor flooding can damage electrical components or introduce contaminants into your system. Shut off power to your HVAC unit and call a professional to assess the damage before turning it back on.
Should I try resetting my furnace during an emergency?
Resetting the furnace once can sometimes resolve minor glitches. However, repeatedly resetting it during an emergency can damage the system further. If a single reset doesn’t work, turn it off and contact a professional.
Why is water pooling around my outdoor heat pump in winter?
Water pooling can occur when your heat pump defrosts. However, if the water freezes and restricts airflow or the unit becomes encased in ice, it may need immediate service. Call a professional to assess and prevent further damage.
Can I run my furnace fan if the heating element is broken?
Yes, running the fan can help circulate air while waiting for repairs, but it won’t provide heat. Make sure you’re using safe supplemental heating options and call for emergency furnace service.
Should I call for emergency service if my gas furnace pilot light keeps going out?
If your pilot light repeatedly goes out, it’s a sign of a malfunctioning thermocouple or gas valve. While not always an emergency, gas-related issues can become dangerous if ignored, so call a professional promptly to diagnose the problem.
How can I tell if it’s safe to stay home during an HVAC emergency?
Stay home only if you have a safe alternative heat source and no risks like gas leaks, carbon monoxide, or dangerously low indoor temperatures. If you’re uncertain, evacuate and contact emergency services for guidance before arranging HVAC repairs.
