Frequently Asked Questions
How much does heating repair cost in Raleigh, NC?
Heating repair costs in the Raleigh area typically range from $150 to $900, depending on the specific problem and system type. Common repairs like ignitor replacement run $150 to $300, a blower motor replacement costs $400 to $900, and a thermocouple replacement is usually $100 to $250. Most HVAC companies charge a diagnostic fee of $89 to $150 that is often waived if you proceed with the repair. After-hours or weekend emergency calls may add $100 to $200 to the total. At Icy Hot Heating & Air Conditioning, we provide upfront pricing before any work begins so there are no surprises — call (919) 673-7667 to schedule a diagnostic.
Why is my heater running but not blowing warm air?
Several issues can cause a heating system to run without producing warm air. The most common culprit is a dirty air filter — when the filter becomes clogged, airflow drops so dramatically that the heat exchanger overheats and trips the high-limit safety switch, shutting down the burners while the blower continues running. Other causes include a malfunctioning thermostat set to fan only mode, a faulty ignitor or pilot light that prevents the burners from lighting, low refrigerant in a heat pump system, or a broken reversing valve that keeps the heat pump stuck in cooling mode. Check your filter and thermostat settings first. If those are fine, the issue likely requires a licensed technician to diagnose safely — schedule a visit and we’ll pinpoint the issue.
What are the most common furnace problems?
The five most frequent furnace problems our technicians see in the Raleigh-Durham area are: (1) dirty or clogged filters causing overheating and short cycling, (2) faulty ignitors or flame sensors that prevent the burners from lighting, (3) worn blower motor bearings that cause loud squealing and eventually blower failure, (4) cracked heat exchangers that pose carbon monoxide risks — especially in furnaces over 15 years old, and (5) thermostat wiring issues or dead batteries causing communication failures. Most of these problems are preventable with annual maintenance. Icy Hot Heating & Air Conditioning’s tune-up service includes a thorough inspection of all five of these common failure points.
How do I know if my heat exchanger is cracked?
A cracked heat exchanger is one of the most serious furnace problems because it can leak carbon monoxide — an odorless, colorless gas — into your home. Warning signs include a yellow or flickering burner flame (it should be steady and blue), soot buildup around the furnace, a strong chemical or formaldehyde-like smell when the system runs, excessive condensation on windows near the furnace, and frequent headaches or flu-like symptoms among household members during heating season. A cracked heat exchanger is not a DIY diagnosis — it requires a professional inspection with a combustion analyzer or camera scope. If your furnace is over 15 years old, we strongly recommend scheduling an inspection before each heating season.
Why does my heating system keep turning on and off (short cycling)?
Short cycling — when your heater runs for only a few minutes before shutting off and restarting — wastes energy and accelerates wear on components. The most common cause is a clogged air filter restricting airflow, causing the system to overheat and trip the safety limit switch. Other causes include an oversized system that heats the space too quickly, a malfunctioning thermostat or misplaced temperature sensor, a failing flame sensor (in gas furnaces), or a refrigerant leak in heat pumps. Start by replacing your air filter — this solves the problem roughly 40% of the time. If the issue persists, call Icy Hot Heating & Air Conditioning at (919) 673-7667. Short cycling should be addressed promptly because it dramatically shortens equipment lifespan.
Is it worth repairing a 20-year-old furnace?
In most cases, investing in major repairs on a 20-year-old furnace is not cost-effective. At that age, the system is already past its expected lifespan of 15 to 20 years, and even if one component is repaired, other parts are likely nearing failure as well. A 20-year-old furnace also operates at significantly lower efficiency than modern models — older units are typically 70-80% AFUE compared to 95-98% for today’s high-efficiency furnaces, meaning you are losing 20-30 cents of every heating dollar up the flue. However, minor repairs under $300 — like replacing a thermocouple or flame sensor — may be reasonable to buy time while you budget for replacement. Icy Hot provides honest repair vs. replace recommendations based on the specific condition of your equipment.
How quickly can a heating repair technician come to my home?
Response times vary depending on the season and time of day. During peak heating season (December through February), most Raleigh HVAC companies schedule standard repairs within 24 to 48 hours. Emergency no-heat calls typically receive same-day or next-morning service. Icy Hot Heating & Air Conditioning offers 24/7 emergency heating repair service throughout the Raleigh, Durham, Cary, and surrounding Triangle communities. For emergency no-heat situations, call (919) 673-7667 any time — day or night. To avoid the rush, scheduling your annual maintenance in early fall ensures your system is inspected and tuned before the coldest weather hits.
