Heating Emergencies We Handle

Some heating problems can wait for a scheduled appointment. Others become more pressing when the system stops producing heat, repeatedly shuts itself down, or begins showing signs of a potentially unsafe failure. Northern Air diagnoses urgent heating problems in Fort Collins and determines what needs to be addressed to restore proper operation.

Complete Loss of Heat

If the heating system is running without producing heat, or will not start at all, we can troubleshoot the equipment to determine what interrupted operation. Depending on the system, the cause may involve ignition, electrical components, controls, circulation, or another mechanical failure.

Furnace Breakdowns

Furnaces can fail because of ignition problems, blower issues, electrical faults, overheating, failed controls, and other component problems. When a furnace failure cannot reasonably wait for a standard appointment, our technicians can diagnose the issue and determine the appropriate heating repair.

Boiler Heating Failures

A boiler that stops heating or circulating hot water can leave a property without adequate heat during freezing weather. We troubleshoot boiler pressure, circulation, controls, ignition, leaks, and related components when determining what caused the failure. Northern Air also provides dedicated boiler services for hydronic heating equipment.

Heat Pump Problems

Heat pumps can experience electrical, refrigerant, airflow, defrost, and control problems that interfere with heating. If your system suddenly stops keeping up or will not operate, our technicians can evaluate the equipment and determine whether heat pump service is needed.

Electrical and Control Failures

A heating system that repeatedly trips a breaker, will not respond to its controls, or shuts down unexpectedly may have an electrical or control-related problem. Avoid repeatedly resetting breakers or restarting equipment that continues to fail. Our technicians can test the system to locate the source of the problem.

What to Do When Your Heat Goes Out

If your heat suddenly stops working, a few basic checks can help you understand what is happening without taking apart the equipment. Start by confirming that the thermostat is set to heat and that the temperature setting is above the current indoor temperature. You can also check whether the furnace or heating system has power and whether an accessible air filter is heavily clogged.

If the system still will not heat, repeatedly shuts down, trips its breaker again after being reset, or shows signs of an electrical or mechanical problem, stop troubleshooting and request service. Avoid opening equipment panels or attempting to repair internal heating components yourself.

During a prolonged outage, keep exterior doors closed and limit unnecessary heat loss while waiting for service. If indoor temperatures are approaching freezing, take appropriate steps to protect plumbing as well. Northern Air’s 24/7 emergency HVAC services are available for urgent heating and cooling problems, with a 24/7 answering service for requests outside regular business hours.

Why Our Customers Keep Coming Back When the Heat Goes Out

An unexpected heating failure can be stressful, especially when temperatures are falling quickly. Customers who already know Northern Air have a team they can call again when their furnace, boiler, or other heating equipment suddenly stops doing its job.

  • 24/7 answering service. Heating problems do not follow business hours, so customers can reach our answering service around the clock when an urgent issue develops.

  • Experience that stays on the team. Northern Air technicians average 14 years with the company, giving returning customers access to an established team with substantial hands-on HVAC experience.

  • Troubleshooting across heating systems. Our technicians work with furnaces, boilers, heat pumps, controls, and related equipment, which helps when the cause of a heating failure is not immediately obvious.

  • Residential and commercial response. Customers can turn to Northern Air for urgent heating problems at home as well as unexpected failures affecting commercial properties.

  • NATE-certified technicians. Our technicians receive technical training that supports accurate diagnosis when a heating system fails unexpectedly.

  • Support after the emergency is resolved. Customers can continue working with the same company for future repairs, maintenance, and equipment needs instead of starting over with a different HVAC provider.

Don’t Wait Out a Heating Failure

When the heat is gone and Fort Collins temperatures are falling, waiting to see if the system starts working again can leave your property getting colder by the hour. Northern Air can diagnose the failure, determine what needs attention, and work to restore heat to your home or business.

If your heating system has stopped working or developed a problem that cannot wait for a routine appointment, request emergency heating repair with Northern Air. Our 24/7 answering service is available when urgent heating problems happen outside normal business hours.
