Emergency HVAC Service in Plymouth & the Twin Cities West Metro

An HVAC problem may require urgent attention when it creates a safety concern, leaves your home without heat during dangerously cold weather, causes extreme indoor temperatures, involves electrical problems, or could cause additional damage to the system or your home.

If you're unsure how serious the problem is, call us. We can help determine the appropriate next step based on what your system is doing and the conditions in your home.

Our phones are answered 24/7 so you can reach a real person when an HVAC problem occurs. We prioritize urgent heating and cooling problems and provide same-day service when technician availability allows.

Calling anytime does not necessarily mean a technician can be dispatched immediately, but our team can help assess the situation and determine the next available service option.

Start by checking that your thermostat is set to heat, the temperature setting is above the current room temperature, and the furnace has power. You can also check whether the furnace filter is severely restricted.

If the furnace still won't run, repeatedly shuts down, or isn't producing heat, it is time to have the system professionally diagnosed. During Minnesota winter conditions, a complete loss of heat can become urgent quickly.

A furnace can run without properly heating because of several issues, including ignition problems, airflow restrictions, control problems, failed components, or the furnace shutting itself down on a safety limit.

The important step is determining why the furnace isn't producing or delivering heat rather than replacing parts based on symptoms alone.

A suspected natural-gas leak should be treated as a safety issue. Do not attempt to diagnose or repair a suspected gas leak yourself. Leave the affected area and contact your gas utility or emergency services from a safe location for guidance.

Once the area has been determined safe, an HVAC technician can inspect furnace-related problems as appropriate.

Treat a carbon monoxide alarm as a potential safety emergency. Move everyone to fresh air and follow the alarm manufacturer's emergency instructions. Contact emergency services or the appropriate local authority from a safe location.

Do not rely on an HVAC appointment as the first response to an active carbon monoxide alarm.

An air conditioner can run without cooling because of airflow problems, a failed capacitor or motor, refrigerant problems, electrical issues, a frozen evaporator coil, compressor problems, or other equipment failures.

Because several different failures can create the same symptom, an accurate diagnosis is more useful than assuming the system simply needs refrigerant.

First verify that the thermostat is set to COOL and that the temperature setting is below the current indoor temperature. If the indoor fan is running but the air isn't getting cold, the outdoor equipment or refrigeration system may not be operating correctly.

If basic thermostat and filter checks don't resolve the problem, schedule an HVAC diagnostic rather than continuing to run a system that isn't cooling properly.

If the indoor blower is operating but the outdoor AC unit isn't, the problem could involve electrical power, controls, a capacitor, contactor, fan motor, compressor, or another component.

Avoid opening electrical panels or attempting capacitor repairs yourself. HVAC equipment can retain dangerous electrical energy even after power has been switched off.

Ice on the refrigerant lines or indoor evaporator coil can be caused by restricted airflow, dirty equipment, blower problems, refrigerant issues, or other system conditions.

Continuing to operate a frozen air conditioner can make diagnosis difficult and may contribute to additional problems. Turn off cooling and arrange for the cause of the freezing to be diagnosed.

Water around an indoor HVAC unit should not be ignored. A clogged condensate drain, drain-pan problem, frozen coil, or other issue can allow water to escape from the system.

If water is actively damaging ceilings, walls, flooring, or nearby electrical equipment, shut the system down when safe to do so and request service promptly.

Frequent short cycling can indicate thermostat issues, airflow restrictions, overheating, electrical problems, equipment sizing issues, or a system safety control shutting equipment down.

It isn't always an emergency, but repeated cycling should be diagnosed because it can reduce comfort and place unnecessary stress on HVAC components.

Heat pump problems can involve airflow, controls, electrical components, refrigerant, the outdoor unit, reversing valve, or other system components. In cold weather, the issue could also involve the system's auxiliary or backup heat.

If your heat pump can't maintain a safe or comfortable indoor temperature, schedule a professional diagnostic.

Some frost on an outdoor heat pump can be normal during cold weather, and the system periodically enters a defrost cycle to remove it.

A unit that becomes heavily encased in ice, doesn't appear to defrost, or stops heating the home properly should be inspected.

It depends on the problem. If you notice burning odors, unusual electrical behavior, significant leaking, heavy ice buildup, or equipment making severe or abnormal noises, shutting the system off may help prevent additional damage when it is safe to do so.

For suspected gas or carbon monoxide problems, leave the affected area and follow emergency guidance rather than remaining in the home to troubleshoot equipment.

Homeowners can usually verify thermostat settings, replace or inspect an accessible air filter, confirm that obvious HVAC switches haven't accidentally been turned off, and look for visible ice or water around the equipment.

Avoid opening electrical compartments, bypassing safety controls, handling refrigerant, or attempting repairs involving gas or combustion equipment.

No. A sudden HVAC failure does not automatically mean the furnace, air conditioner, or heat pump needs to be replaced. Some failures can be corrected by repairing a specific component.

Replacement may make more sense when equipment has a major failure, is near the end of its useful life, has recurring problems, or the cost and expected life of the repair no longer make financial sense. We diagnose the problem first and explain the available options before recommending replacement.

We prioritize urgent heating and cooling problems and provide same-day appointments when technician availability allows. Whether the repair can be completed during the initial visit depends on the diagnosis, parts required, equipment type, and availability of those parts.

Yes. Brass Tacks Plumbing, Heating & Cooling diagnoses urgent furnace and heating problems, including furnaces that won't start, aren't producing heat, repeatedly shut down, or aren't keeping the home warm.

Yes. We diagnose urgent air-conditioning problems such as an AC system that stops cooling, blows warm air, freezes up, leaks water, repeatedly shuts down, or has an outdoor unit that isn't operating correctly.

Yes. We diagnose heat pumps that stop heating or cooling, develop ice problems, fail to switch modes, make unusual noises, or cannot maintain the home's temperature.

Tell us whether the problem involves heating, cooling, or a heat pump; what the system is doing; when the problem started; whether you see water or ice; whether there are unusual sounds or odors; and whether the system is currently running.

You don't need to diagnose the problem yourself. Those details simply help us understand what you're experiencing.

During very cold Minnesota weather, don't wait until the indoor temperature has fallen dramatically before requesting service. Loss of heat can become more serious as the home cools and can eventually put plumbing and other parts of the property at risk.

Call as soon as you realize the furnace or heating system isn't recovering normally so the problem can be assessed.
