Emergency HVAC Repair Services

At All-Temp, we understand that an HVAC issue can’t always wait for business hours. That’s why we offer 24/7 emergency services for HVAC systems, including boilers, heat pumps, furnaces, central AC, ductless mini-splits, and more! Our expert technicians provide fast response times and can diagnose the most complex issues to get you the necessary repairs.

Contact our team if you’re experiencing issues like:

  • No power: If your heating or cooling won’t turn on, you could have an electrical issue. This is considered an emergency, especially if outdoor temperatures are extreme or your home has vulnerable family members like older adults or infants.
  • Reduced airflow: Reduced airflow could result from clogs or other issues and can lead your system to overheat.
  • Leaks: Any leaks indicate that your HVAC isn’t operating properly. Whether it’s water or refrigerant, these leaks can damage your property and should be handled immediately.
  • Strange sounds: Odd noises like grinding or clanking often indicate that an internal component is loose or failing and should be fixed before the system suffers further damage.

All Temp has been our family's AC installation and service team for almost 24 years. They recently replaced my parent's complete system after it failed during the hottest week of the year. They did an excellent job and completed everything in less than 6 hours! Great…
