What is Considered an HVAC Emergency?

Not every HVAC problem requires an emergency response, but some situations shouldn’t wait for a regular appointment.

You may need emergency service if:

  • Your heating system stops working during dangerously cold weather
  • Your air conditioner stops cooling during extreme heat
  • Your equipment is making unusual sounds and experiencing a loss of operation
  • You smell burning or gas that indicates a potential safety concern
  • You suspect you have a refrigerant leak that requires immediate attention

If you are unsure whether your situation requires emergency HVAC repair, it is better to have a professional evaluate it than to attempt a repair yourself.

Emergency Heating and Cooling Problems We Handle

Thornton provides 24/7 emergency HVAC service for urgent heating and cooling problems affecting homes and light commercial properties. Whether your system has stopped working, is no longer providing adequate temperature control, or is showing signs of a serious mechanical or electrical problem, our technicians can evaluate the equipment and determine the appropriate next step.

Emergency Heating Services

Heating problems can become urgent quickly during the inevitable Chicagoland cold snaps. The team at Thornton can resolve all sorts of emergency heating issues, including:

  • Furnace failures or complete loss of heat
  • Boiler problems affecting heating operation
  • Heat pump heating failures
  • Ductless heating system problems
  • Sudden equipment failures that leave a property without adequate heat
  • Serious mechanical or electrical issues affecting system operation

Our technicians will assess your system to identify the issue and determine whether you need emergency heating repair or a new furnace, heat pump, or boiler. Our goal is to address your immediate problem with the solution that makes sense for your home.

Emergency Air Conditioning Services

A major cooling failure can quickly make your home uncomfortable during extreme summer heat. Thornton is here for all your urgent air conditioning problems, including:

  • Major AC system breakdowns
  • Complete loss of cooling
  • Serious equipment problems affecting system operation
  • Sudden airflow loss
  • Refrigerant-related problems requiring professional attention
  • Electrical or thermostat issues preventing the system from operating

Depending on the condition of your cooling system, our emergency air conditioner repair services may be able to get it working again or let you know if you need a new AC installed. We’ll explain the problem you’re experiencing and work to fix it as quickly as we can.

What to Do and Not to Do When Your HVAC System Fails

If your HVAC system suddenly stops working, do not attempt any electrical, refrigerant, or mechanical repairs on your own. These system components require professional knowledge and, in some cases, specialized equipment to diagnose and service safely.

However, if your system stopped operating and there is no immediate safety concern, you can check your thermostat settings to see if there’s a quick fix or setting change. But if you notice smoke, sparking, a strong unusual odor, or other potential hazards, then you should contact HVAC professionals and potentially first responder emergency services if there are sparks or any other immediate dangers.

When you need to call for emergency HVAC repairs, it’s helpful to have basic information on hand, like what type of equipment you have, whether the system stopped suddenly, and anything unusual you noticed before the failure. This gives our technicians useful context they’ll need when evaluating the problem and figuring out how to fix it.

What to Expect During an Emergency HVAC Service Call

We offer 24 hour HVAC repair because we’re equipped to respond to urgent heating and cooling problems outside standard business hours. Emergency hours are available 24/7, including evenings, weekends, and when a typical HVAC appointment may not be available.

During an emergency service visit, our technician will:

  • Evaluate your HVAC system to find the source of the problem
  • Assess the equipment condition and identify the appropriate repair
  • Explain the recommended work before proceeding
  • Answer questions about the problem and available options
  • Perform the repair if the issue can be addressed during the visit
  • Assist you in understanding your options if a new system is needed

Our certified technicians are trained to work on a range of heating and cooling equipment brands and models. With more than 60 years in the industry, the Thornton team brings decades of technical knowledge and professionalism to every emergency service call.

Our techs are equipped to address a broad range of HVAC needs. While the availability of specific parts or repairs can vary depending on your equipment and the nature of your emergency, our stocked service vehicles help technicians address your HVAC emergencies as efficiently as possible.

Call Thornton for 24/7 Emergency HVAC Service

Some HVAC problems can wait for a scheduled appointment. Others cannot. A sudden heating or cooling failure can leave you unsure of what to do next, especially if it occurs outside normal business hours. If that happens, it’s important that you don’t panic and have someone to call. Our 24/7 team of experts is ready to help get your system working again.

You deserve to know what is happening with your HVAC system and what your options are when something goes wrong, so contact us to speak with our team about the heating or cooling issue you’re experiencing, and we’ll take care of the emergency repairs needed to get your heating or air conditioning system up and running again.
