Emergency Heat Pump Service in Raleigh, NC

24/7 emergency heat pump service — we answer your call

Emergency Heat Pump Service for Raleigh-Durham Homeowners

Heat pumps are the workhorses of Raleigh-area comfort — handling both heating and cooling through North Carolina’s unpredictable weather. When your heat pump fails, you lose your entire HVAC system, not just heating or cooling. Icy Hot provides emergency heat pump service around the clock, every day of the year. Call (919) 673-7667 and a real person will answer and dispatch a technician to your home.

Heat pump emergencies can happen in any season. A failed compressor in January leaves you without heat. A refrigerant leak in July means no cooling. And because heat pumps use both refrigerant and electrical systems, diagnosing the root cause requires specialized training that our NATE-certified technicians bring to every service call.

When to Call for Emergency Heat Pump Service

Some heat pump issues can wait for a scheduled appointment. Others cannot. Call for emergency service if you experience any of the following situations:

Complete System Failure

If your heat pump won’t turn on at all — no fan, no compressor, no response to thermostat adjustments — check your breaker panel first. If breakers haven’t tripped and the thermostat has power, you likely have a failed contactor, control board, or capacitor. Call for emergency service, especially during extreme temperatures.

Ice Buildup That Won’t Defrost

Heat pumps naturally frost over during winter operation and run defrost cycles to clear ice. But if your outdoor unit is encased in solid ice for more than 2 hours, the defrost cycle has failed. Running an iced-over heat pump damages the compressor and fan motor. Do NOT try to chip ice off the unit or pour hot water on it — call a technician.

Refrigerant Leak Signs

Hissing or bubbling sounds near the outdoor or indoor unit, warm air from vents when heating or cooling is on, ice forming on refrigerant lines, or a sudden drop in performance all suggest a refrigerant leak. Refrigerant is essential for heat transfer — without it, your heat pump cannot heat or cool. Leaks worsen over time and can damage the compressor if the system runs low.

Electrical Burning Smell

A burning or acrid smell from your heat pump’s indoor or outdoor unit indicates overheating wiring, a failing motor, or a burned-out capacitor. Turn the system off at the thermostat and the breaker, and call for emergency service. Do not restart the system until a technician has inspected it.

Loud Grinding, Screeching, or Banging

Metal-on-metal grinding usually means failing compressor bearings — a catastrophic failure if not addressed quickly. Screeching indicates a worn fan motor bearing or slipped belt. Banging can be a loose component inside the compressor. All of these sounds warrant immediate shutdown and service.

What to Do While Waiting for Emergency Service

  • Check the thermostat — Verify it’s set to the correct mode (Heat or Cool) and the temperature is set above (or below) the current room temp. Replace batteries if applicable.
  • Check the breaker panel — Reset any tripped breakers once. If they trip again immediately, do not keep resetting — there’s an electrical fault.
  • Switch to Emergency/Auxiliary Heat — If your heat pump won’t heat but the air handler works, switching to EM HEAT activates backup electric heat strips. This is expensive to run but prevents freezing while you wait for repair.
  • Don’t force a defrost — Never pour hot water on a frozen outdoor unit or try to chip ice off with tools. You can damage refrigerant lines and fan blades.
  • Keep vents and returns clear — Make sure furniture, rugs, and curtains aren’t blocking airflow. Restricted airflow makes any heat pump problem worse.
  • Note what happened — When did the problem start? What sounds or smells did you notice? Was there a power outage? This information helps our technician diagnose faster.

Emergency Heat Pump Repair vs. Replacement

Not every emergency ends with a repair. Sometimes replacing your heat pump is the smarter investment. Here are the factors our technicians help you evaluate:

  • Age — Heat pumps typically last 10-15 years. Emergency repairs on a 12+ year old unit may not be the best investment when a new system offers better efficiency and a full warranty.
  • Compressor Failure — Compressor replacement costs $1,500-$3,000+. For units over 8 years old, full system replacement often makes more financial sense.
  • Refrigerant Type — If your system uses R-22 (Freon), which was phased out in 2020, refrigerant costs are prohibitively high ($100-$175 per pound). Upgrading to a modern R-410A or R-454B system is the smart long-term choice.
  • Efficiency Gains — A heat pump from 2010 might be rated at 13 SEER. Today’s units reach 18-22 SEER, potentially cutting your energy bills by 30-40%.
  • Don’t Rush — Emergency repair can stabilize your system while you take time to evaluate replacement options. We’ll never pressure you into a decision at 2 AM.

Frequently Asked Questions

What are signs of a heat pump emergency?
Signs that require immediate emergency service include complete system failure during extreme temperatures (below 32°F or above 95°F), solid ice buildup on the outdoor unit lasting more than 2 hours, a burning or electrical smell coming from either the indoor or outdoor unit, hissing sounds indicating a refrigerant leak, and loud grinding or screeching noises from the compressor or fan motor. If anyone in your home experiences headaches, dizziness, or nausea alongside unusual system behavior, leave the home and call 911 first — while heat pumps don’t produce carbon monoxide, electrical failures can create dangerous conditions.
What should I do if my heat pump is frozen solid?
Do not chip ice off the unit with tools or pour hot water on it — both can damage refrigerant lines and fan blades. First, check whether the defrost cycle is running (you’ll hear the compressor change tone and the outdoor fan stop briefly). Check that airflow around the outdoor unit isn’t blocked by debris, leaves, or snow. Make sure the unit is elevated off the ground and hasn’t settled into standing water. If the unit remains encased in ice after 4 hours, the defrost timer, defrost control board, or reversing valve has likely failed and needs professional repair. In the meantime, switch to EM HEAT on your thermostat to keep your home warm using backup electric heat strips.
What is the difference between emergency heat and auxiliary heat?
Auxiliary heat (AUX) activates automatically when outdoor temperatures drop below approximately 35°F and the heat pump alone can’t keep up with demand. The backup electric heat strips supplement the heat pump, which continues running. Emergency heat (EM HEAT) bypasses the heat pump entirely and runs only the electric resistance heat strips. EM HEAT should only be used when the heat pump itself is broken — it costs 2-3 times more to operate than a heat pump because electric resistance heating is far less efficient. If your thermostat shows AUX heat frequently above 40°F, your heat pump may need service. If you’re running EM HEAT, call for repair as soon as possible.
How much does emergency heat pump repair cost?
Emergency heat pump repair costs vary depending on the issue. After-hours diagnostic fees typically range from $150-$300. Common repair costs include: capacitor replacement ($150-$400), contactor replacement ($150-$350), fan motor replacement ($300-$800), defrost board replacement ($200-$500), and compressor replacement ($1,500-$3,000+). After-hours labor typically carries a 30-50% premium over standard business hours rates. At Icy Hot, we provide upfront pricing before starting any work, so you know exactly what you’ll pay before giving approval — even in the middle of the night.
Why is my heat pump not heating in cold weather?
Several issues can cause a heat pump to stop heating in cold weather. The most common is an iced-over outdoor unit where the defrost cycle has failed. Low refrigerant charge reduces heating capacity significantly — if you notice the system running constantly without reaching the set temperature, a refrigerant leak may be the cause. A failed reversing valve can leave the system stuck in cooling mode, blowing cool air when it should heat. Defrost board failure prevents the unit from clearing normal frost buildup. Failed supplemental heat strips mean the system can’t keep up when temperatures drop below 35°F. Heat pumps do lose efficiency as temperatures drop, but a properly functioning unit should still heat your home in Raleigh’s typical winter conditions (lows in the 25-35°F range).
Is a refrigerant leak in my heat pump dangerous?
Refrigerant itself has low direct toxicity, but it can displace oxygen in enclosed spaces like small mechanical rooms, creating a suffocation risk. The bigger immediate concern is damage to your heat pump — running a system with low refrigerant charge forces the compressor to work harder and overheat, leading to premature and expensive compressor failure. From an environmental standpoint, R-410A (the most common modern refrigerant) is not ozone-depleting but is a potent greenhouse gas. Older systems using R-22 (Freon) are both ozone-depleting and increasingly expensive to recharge ($100-$175 per pound). Refrigerant leaks always require professional repair — the leak must be located, repaired, the system evacuated of moisture, and recharged to the manufacturer’s exact specifications.
How long do heat pumps last, and when should I replace instead of repair?
Heat pumps typically last 10-15 years with proper maintenance. Consider replacement over repair if: the compressor fails on a unit older than 10 years (compressor replacement costs $1,500-$3,000+), your system uses R-22 refrigerant (phased out in 2020, making recharges prohibitively expensive), or the repair cost exceeds 50% of a new system’s price. Modern heat pumps rated at 18-22 SEER offer dramatically better efficiency compared to older 13 SEER units — potentially reducing your energy bills by 30-40%. During an emergency, our technicians can stabilize your current system with a repair while you take time to evaluate replacement options. We provide honest assessments and will never pressure you into replacing a system that has good years of service remaining.
