When To Call for Emergency HVAC Repairs
HVAC issues don’t always happen during business hours. If your heating or cooling system fails at an inconvenient or dangerous time, Cahill is ready to respond. Below are a few situations that warrant an emergency call:
- No heat during freezing temperatures: In a Chicago winter, a lack of heating isn’t just uncomfortable, it can be dangerous, especially for young children, seniors, and pets.
- No cooling during extreme heat: Excessive indoor heat can be dangerous in the summer.
- Burning smells or smoke from your HVAC unit: This could signal an electrical issue or overheating component that needs urgent attention.
- Unusual noises or loud banging sounds: These may point to a serious internal problem that could worsen quickly if not addressed.
- Water leaks around HVAC equipment: Leaks can cause water damage or indicate a frozen coil or condensate line blockage.
- Carbon monoxide alarm triggered: If your CO detector goes off, leave your home and call for emergency service immediately. This is a critical safety issue.

Emergency HVAC FAQs
If your system is working (though not perfectly) and no safety issues are present, it’s usually okay to wait. Examples include uneven temperatures, minor noise, or dirty filter alerts. Turn off the HVAC system if you detect burning smells, smoke, or strange sounds. If it’s a heating issue, use blankets and close off unused rooms to retain heat. For cooling issues, use fans and stay hydrated until help arrives.When should I wait for normal business hours instead of calling for emergency services?
