Smell gas or hear a carbon monoxide alarm?

Leave the house first. Call 911 or your gas company from outside, and do not flip switches on the way out. Call for furnace repair after the house has been checked and cleared.

Furnace and heater faults that need a technician

Check the thermostat, the filter and the breaker before you call. If they are fine, one of these is the likely cause.

The furnace will not ignite

The burners click and nothing lights, or the furnace starts and shuts off within seconds. A dirty flame sensor or a worn ignitor is the usual cause, and both are small repairs.

The heater blows cold air

On a gas furnace this often means the burners shut off because a clogged filter let the unit overheat. On a heat pump it can be the defrost cycle, which is normal for a few minutes and a fault if it lasts.

No heat at all

A tripped limit switch, a failed control board or a dead transformer. These need a technician with a meter.

Banging, squealing or rattling

Banging at start up, a squeal from the blower, or panels that rattle. Blower bearings and loose parts are common, and they are cheaper to fix before they fail.

The heater turns on and off every few minutes

Short cycling points to restricted airflow, a unit that is too big, or a thermostat fault.

Gas furnace or heat strips: what is in your house?

Look at the indoor unit. If there is a gas line and a flue pipe, it is a gas furnace. If the outdoor unit is a heat pump and the indoor unit has no gas line, the backup heat comes from electric strips, which draw a lot of power on cold nights. Tell us which one you have when you call.
Heat pumps have their own faults and their own page. Read the heat pump guide if that is your system.

What February 2021 taught Cedar Park about heating

Anyone who was here in February 2021 knows what a long freeze does to a house. Heaters ran for days, and many systems were not ready for it. A furnace tune up in the autumn checks the ignition, the flame sensor, the heat exchanger and the blower before you need them. See what a tune up covers.
If a freeze catches you without heat, the emergency steps cover what to do while you wait.

Cedar pollen and your furnace filter

Cedar pollen peaks from December to February, which are the same weeks the heater runs most. A filter that catches pollen fills quickly. A blocked filter makes the furnace overheat and shut down on its limit switch. Check the filter every month in winter, and change it when it looks grey.
Cedar season fills filters fast.
  1. A clean filter passes air freely
  2. A clogged filter makes the furnace overheat

Furnace replacement and installation

Gas furnaces often last 15 to 20 years. Replace one when the heat exchanger is cracked, because that is a carbon monoxide risk. Replace it when the repair quote is more than half the cost of a new unit, or when the heat is uneven and the furnace is near the end of its life.
Cedar Park winters are mild, so a high efficiency furnace takes longer to repay its extra cost than it would in a cold state. Ask us to compare a standard unit and a high efficiency one for your house. If the outdoor AC is also old, ask for a quote on the whole system. See how a new AC is sized and quoted.

Questions about furnace and heating repair in Cedar Park

Start with the thermostat, which should say heat with the fan on auto. Then check the filter. A clogged filter can make the furnace overheat and stop the burners while the fan keeps running. If the filter is clean and the air stays cold, call for a technician.

Once a year, in the autumn before the first cold snap.

No. A crack can let carbon monoxide into the house. Switch it off and call right away. Every house with a gas appliance should have working carbon monoxide alarms.

Often 15 to 20 years with yearly service. Our mild winters mean fewer running hours than in the north.

Yes. See the heat pump guide, or tell us what you have when you call.

Call the same number. Ask about after hours charges before you book. The emergency steps have more.

A dusty smell for the first hour or so is normal, because dust settles on the heat exchanger over the summer. If the smell lasts, or it smells like gas or burning plastic, switch the furnace off. For a gas smell, leave the house and call your gas company or 911.

Warning signs are soot around the burners, a yellow flame in place of a blue one, a carbon monoxide alarm sounding, or a new chemical smell. Only a technician can confirm a crack. Switch the furnace off if you suspect one.

Short cycling usually comes from a clogged filter, a dirty flame sensor, a poorly placed thermostat or an oversized unit. Replace the filter first. If it keeps cycling, call for a technician.

68°F when you are home is the common recommendation, with a few degrees lower when you are asleep or away. In Cedar Park that is enough for most nights.

It depends on the size, the efficiency and the venting. A typical gas furnace swap runs from a few thousand dollars up, and a high efficiency unit with new venting costs more. Ask for a free written quote with both options.

Furnaces made in the last couple of decades almost always use electronic ignition and have no standing pilot. An older unit may have one. If a pilot keeps going out, a technician should check the thermocouple and the gas valve.
