When your furnace blows cold air, won't turn on, cycles constantly, or can't keep your home comfortable, All Year Heating & Air can inspect the system, explain the issue, and recommend practical repair options.
A furnace problem can make a home uncomfortable quickly, especially during cold evenings, early mornings, or when a tenant reports no heat. Some furnace symptoms are comfort problems, while others can point to safety or airflow concerns that should be checked by a professional.
Cold air from the vents can point to thermostat settings, airflow restrictions, ignition issues, burner problems, or a furnace that isn't producing heat properly.
If the furnace runs but the house never warms up, the issue may involve airflow, controls, the blower, burners, or a safety switch shutting the system down.
A furnace that won't start may have a thermostat issue, power issue, ignition problem, control board issue, or safety switch problem.
A furnace that turns on and off repeatedly may be overheating, struggling with airflow, receiving incorrect thermostat signals, or shutting down for safety.
Weak airflow can make rooms uncomfortable even when the furnace is running. Dirty filters, duct restrictions, blower issues, or system performance problems may be involved.
Banging, rattling, grinding, squealing, or buzzing sounds should be checked before they become larger mechanical or electrical problems.
A light dusty smell can happen after a furnace has been idle, but persistent burning odors, smoke, gas smell, or unusual odors should be treated seriously.
If the thermostat is blank, inaccurate, or not calling for heat, the issue may be with settings, batteries, wiring, controls, or the thermostat itself.
Hot and cold rooms can be caused by ducting, airflow, thermostat location, system sizing, or furnace performance issues.
A furnace working harder than normal may use more energy because of airflow restrictions, worn components, controls, or poor system performance.
Furnace problems can come from controls, airflow, startup components, safety switches, the blower system, or combustion-related parts. All Year Heating & Air can inspect the furnace, check the symptoms, and explain what's likely causing the problem before recommending repair.

Some furnace problems should be treated as safety concerns, not just comfort issues. Unusual smells, repeated shutoffs, burning odors, a yellow or unstable pilot flame, smoke, or suspected gas issues should be checked carefully.
If something feels unsafe: turn the furnace off if you can do so safely and call a professional.
If you smell gas: leave the home and contact the appropriate emergency or utility service from a safe location.
If a carbon monoxide alarm sounds: leave the home and call emergency services. Carbon monoxide is odorless and colorless — keep working CO alarms in the home and don't ignore an alarm.
We don't publish DIY repair steps for gas lines, burners, ignition components, flame sensors, heat exchangers, control boards, or other internal furnace parts. Furnace internals should be serviced by a professional.
A reliable furnace repair starts with a clear diagnosis. Our goal is to identify the issue, explain what we found, and help you make a practical decision.
We check the thermostat, airflow, startup sequence, visible system condition, and furnace operation to narrow down the cause of the problem.
You get a clear explanation of what we found, what it means, and which repair options make sense.
If repair is practical, we work to restore heat. If replacement or further evaluation is more sensible, we explain that before moving forward.
A furnace problem doesn't automatically mean the system needs to be replaced. Many issues can be repaired when the furnace is otherwise in good condition and the problem is isolated. In other situations, repeated breakdowns, safety concerns, poor performance, or expensive repairs may make replacement worth discussing. We diagnose the system first, explain the findings, and recommend repair when repair is practical.

Your furnace may blow cold air because of thermostat settings, restricted airflow, ignition problems, burner issues, or a component that's preventing the furnace from producing heat. If basic checks don't solve the issue, schedule a furnace repair diagnosis.
A furnace that won't turn on may have a thermostat problem, tripped breaker, power issue, ignition problem, control issue, or safety switch issue. A technician can inspect the system and identify the cause.
Frequent on-and-off cycling, also called short cycling, may be caused by airflow restrictions, a dirty filter, thermostat problems, overheating, or control issues. Short cycling should be checked because it can put extra stress on the system.
A light dusty smell can sometimes happen when a furnace is used after sitting idle, but a persistent burning smell, smoke, gas odor, or carbon monoxide alarm should be treated seriously. Turn the system off if you can do so safely and contact the appropriate emergency or utility service if there is a safety concern.
Repair may make sense when the issue is isolated and the furnace is otherwise working well. Replacement may be worth discussing if the furnace has repeated breakdowns, poor performance, high repair costs, parts issues, or safety concerns.
