Some furnace problems are annoying, others can damage equipment or affect safety if you ignore them. Call for professional furnace heating repair if you notice:
If you want a deeper checklist before you call, read our guide on signs your furnace needs repair before winter, then schedule service if any of those symptoms look familiar.
When you contact Hot Cold Air, our dispatcher asks a few quick safety questions about gas odors, carbon monoxide alarms, and visible damage. If something sounds unsafe, we will advise you to turn the system off and ventilate the space while we arrange an urgent visit.
During the visit, the technician checks the thermostat, electrical supply, gas line, ignition system, burners, flame sensor, blower motor, heat exchanger, flue, and air filter. For heat pumps, we also inspect the outdoor unit, refrigerant circuit, and defrost controls. The goal is to find the root cause, not just reset the fault.
Once the issue is confirmed, you receive clear repair options with straightforward pricing before any work begins. You will see what needs to be fixed now, what can wait, and what it would cost to replace the system if that is the smarter long term choice.
Most common furnace repair parts, such as igniters, flame sensors, control boards, capacitors, and motors, are stocked on our trucks. We complete the repair, verify gas pressures and electrical readings, and test several full heating cycles to confirm stable operation and correct airflow.
If you approve the repair, your diagnostic fee is credited back. You only pay for the approved work and any parts used, not for the initial troubleshooting.
Before leaving, the technician explains what caused the failure, shows any worn components, and gives simple maintenance tips, such as filter changes or thermostat settings, to help you avoid repeat issues.
Real fixes for no-heat calls, short cycling, gas odors, and uneven rooms. Our licensed technicians diagnose quickly, replace failed parts (igniters, flame sensors, control boards), and restore safe, efficient heating across Chicago and the suburbs. See how a proper repair brings your system back within spec.
At Hot Cold Air, we believe furnace repair pricing should be simple and transparent. Before any work starts, you receive a clear written estimate, so you know exactly what is included and what your options are. If you approve the repair, the diagnostic fee is applied to the job.
The main components of your furnace repair quote include:
Factors that can affect furnace repair cost include:
To avoid unexpected expenses, it is important not to skip regular maintenance. Annual furnace checks and tune ups help catch small issues early, keep your heating system running efficiently, and reduce the risk of costly emergency repairs. At Hot Cold Air, we always provide a full estimate before work begins, so you can plan your budget with confidence and never worry about hidden charges.
Our team provides residential furnace repair for single family homes, townhomes, and condos throughout Chicago and the suburbs. We service all major furnace and heat pump brands, including Carrier, Trane, Lennox, Goodman, Bryant, American Standard, Payne, and many others.
Gas furnaces are the most common heating system in the Chicago area. Typical problems include failed igniters, dirty burners, faulty flame sensors, pressure switch errors, and cracked or leaking vent pipes. We perform combustion checks, verify gas supply and venting, and make sure your system heats efficiently while keeping carbon monoxide levels within safe limits.
Electric furnaces and electric air handlers rely on heating elements, sequencers, and relays instead of burners and gas valves. If your electric furnace is blowing cold air, the issue may be a failed element, tripped limit switch, or airflow restriction. We test each component, reset or replace faulty parts, and confirm that the blower and heater stages work together correctly.
Some homes still use oil furnaces or older heating equipment. These systems need careful cleaning and precise adjustment to operate safely. Our technicians can clean burners and heat exchangers, replace nozzles and filters, and advise you when repair is no longer cost effective compared to replacement.
Heat pumps move heat instead of creating it, which makes them efficient but sensitive to airflow and refrigerant problems. We handle heat pump repair for issues such as icing in winter, stuck reversing valves, noisy outdoor units, and systems that run constantly but do not reach temperature. We also check auxiliary heat strips to keep your home warm during extreme cold.
Most emergency calls begin as small issues that could have been caught during a seasonal tune up. Annual maintenance keeps burners clean, confirms safe operation, and helps your furnace run more efficiently, which can reduce energy costs and extend equipment life.
Our technicians check safety controls, clean or adjust components, verify airflow and temperature rise, and document any developing problems so you can plan ahead. Learn more about our furnace maintenance service and schedule a tune up before the first serious cold snap.
Hot Cold Air is based in Northbrook and serves homeowners throughout Chicago and the surrounding suburbs. Our service area includes communities such as Glenview, Deerfield, Buffalo Grove, Wheeling, Arlington Heights, Wilmette, Evanston, Lincolnwood, Schaumburg, and many nearby neighborhoods.
Because our vans are distributed across the region and supported by local service hubs, we can usually reach you quickly even during peak cold spells when many furnaces fail at the same time.
We’ve got answers. From repair costs to system lifespan and emergency service — here are the most common questions homeowners ask about furnace repair:
Start with the basics. Make sure the thermostat is set to heat and above room temperature, the furnace switch is on, the breaker is not tripped, and the air filter is not completely clogged. If the system still does not start or shuts down after a few seconds, a safety device may be locking it out, and you should schedule service.
There are several common causes. The thermostat fan setting may be on instead of auto, which runs the blower even when the elements are off. Heating elements or sequencers can fail, or a limit switch can open because of restricted airflow. If the air stays cool for more than a few minutes after startup, turn the system off and have a technician check it.
The cost varies based on the issue, but we provide upfront estimates before starting any work. Common repairs range from $150 to $600.
A furnace that will not start may have no power, a loose door switch, thermostat wiring issues, a failed control board, or a safety lockout after repeated failed ignition attempts. Avoid repeatedly resetting the breaker or cycling power, as that can stress components. A professional can read fault codes, test the ignition sequence, and identify the exact reason the system is not turning on.
Short cycling often points to overheating from a dirty filter, blocked vents, or restricted ductwork. It can also be caused by a malfunctioning flame sensor, pressure switch, or oversized furnace that brings the home up to temperature too quickly. Regular maintenance helps prevent these problems, and our technicians can adjust or repair the system if short cycling is already happening.
Yes. We provide 24 hour furnace repair and emergency heating repair across Chicago and the suburbs. If you lose heat during extreme cold, smell gas, or get a carbon monoxide alarm, call us right away and we will prioritize your visit.
Most manufacturers recommend professional maintenance once a year. In the Chicago climate, a fall tune up is ideal, so the furnace is clean, tested, and ready before the first hard freeze. Many homeowners combine a repair visit with a full tune up so the system leaves the appointment in as close to like new condition as possible.
Yes — all our repairs come with a written warranty on both labor and parts.
Do not wait for a complete breakdown on the coldest night of the year. If your system is noisy, unreliable, or already without heat, schedule furnace repair now.
