Signs You Need Furnace Repair

Most furnace problems don’t appear without warning. Your system will typically show clear indicators that something is wrong before it stops working altogether. Catching those signs early means a faster repair, lower cost, and no risk of losing heat in the middle of the night.

Call Advanced Plumbing, Heating and Air if you notice any of the following:

The furnace runs but the house isn’t reaching the temperature set on the thermostat
Airflow from vents is weak or noticeably reduced compared to normal
The air coming from vents feels cool or lukewarm instead of warm
The system is short cycling, turning on and off more frequently than normal
You hear unusual sounds such as banging, rattling, squealing, or rumbling when the system runs
There are burning smells, musty odors, or unusual scents coming from vents
The pilot light or ignition is failing to light or stays lit inconsistently
Your energy bills have increased without a change in usage habits
The system won’t turn on or responds inconsistently to thermostat adjustments

Vacaville winters may be mild compared to colder climates, but overnight temperatures drop enough that a furnace failure is a real problem. If your system is showing any of these signs, schedule a repair before the problem gets worse.

Common Furnace Problems We Fix

Furnace failures can originate in the mechanical components, electrical systems, ignition controls, or heat exchanger. Our technicians are trained to diagnose and repair problems across all major furnace types and brands.

Ignition and heating issues:

Faulty ignitors and pilot lights failing to light
Gas valve problems preventing proper fuel delivery
Flame sensor issues causing the burner to shut off immediately after igniting
Cracked or damaged heat exchangers reducing heating efficiency
Burner problems causing incomplete combustion or uneven heat

Mechanical failures:

Blower motor failures preventing heat distribution through the home
Belt and bearing wear causing noise and reduced airflow
Inducer motor failures affecting combustion and venting
Limit switch failures causing the system to shut down prematurely

Electrical and control issues:

Thermostat malfunctions causing erratic or unresponsive system behavior
Control board failures affecting ignition sequencing and system operation
Wiring problems creating intermittent failures or complete system shutdowns
Tripped high-limit switches from overheating or restricted airflow

Airflow and venting issues:

Clogged air filters causing the system to overheat and shut down
Blocked or damaged flue venting preventing safe exhaust
Ductwork leaks reducing heat delivery to living spaces
Pressure switch failures related to venting or inducer operation

Whatever your furnace is doing, we’ll identify the root cause and give you a clear explanation before any repair work begins.

Frequently Asked Questions

Why is my furnace running but not producing heat?

The most common causes are a faulty ignitor, a failed flame sensor, a tripped high-limit switch, or a gas valve issue preventing fuel delivery. Each of these prevents the burner from producing heat even when the blower is running. A technician can pinpoint the specific cause quickly with a proper inspection.

Is it safe to run my furnace if I smell something burning?

A faint burning smell at the start of heating season is often just dust burning off the heat exchanger and typically clears within a short time. A persistent burning smell, an electrical odor, or any smell that gets stronger over time is a different situation. Shut the system off and call for service. A cracked heat exchanger or an electrical problem requires immediate professional attention.

How long does a furnace repair typically take?

Most furnace repairs are completed in a single visit lasting one to three hours. If a specific part needs to be ordered, we’ll let you know upfront and schedule a follow-up as quickly as possible so your home isn’t without heat any longer than necessary.

What causes a furnace to short cycle?

Short cycling is most commonly caused by a clogged air filter restricting airflow and triggering the high-limit switch, an oversized furnace, a failing flame sensor, or a heat exchanger problem. It puts significant stress on the system and will shorten equipment life if not addressed. A technician can identify the specific cause and resolve it before further damage occurs.

How do I know if my furnace heat exchanger is cracked?

A cracked heat exchanger is a serious safety concern because it can allow combustion gases including carbon monoxide to enter the living space. Symptoms include soot around the furnace, headaches or flu-like symptoms in household members when the heat is running, visible cracks or rust on the heat exchanger itself, and a carbon monoxide detector alarm. If you suspect a cracked heat exchanger, shut the system off and call for service immediately.
