Our AC quit on the hottest day of the week. They came out the same afternoon, explained exactly what failed, and had us cool again within two hours.
Heating systems here sit idle for months, so the first cold night often reveals the problem. The cause is usually an ignition issue, a safety switch, a blower problem, or on a heat pump, a refrigerant or defrost issue.
If you smell gas, leave the house and call your gas utility first. Safety always comes before comfort.
What You Notice
Common signs include:
The system tries to start and shuts off again
Cool air blowing from the vents
No sound from the furnace at all
A heat pump covered in ice
Rooms that never warm up
Could Also Be
Signs It Is This
The furnace clicks several times and then stops
You hear the blower but the air stays cool
The thermostat display is blank
Repeated on and off cycling
Is It Safe to Keep Running?
If you smell gas, leave the home right away and call your gas utility from outside. Do not use switches or flames.
Never use an oven or outdoor heater to warm your home. They can produce carbon monoxide.
What You Can Check Yourself
Check the thermostat is set to heat and the batteries are fresh
Replace a dirty air filter
Make sure the furnace switch and breaker are on
Make sure vents are open and unblocked
If the furnace still will not run, a technician should check the burner and safety controls.
Go Deeper
Why It Happens
A furnace needs air, gas, and a spark to run safely, with safety switches that shut it down when something is wrong. A fault in any one of them stops the heat, which is exactly how the system is meant to protect your home.
Parts Involved
Thermostat and control board
Igniter and flame sensor
Gas valve and burners
Blower motor and capacitor

What a Technician Does
A technician tests the controls, ignition, airflow, and safety switches, explains what failed, and gives you a written price before repairing it.
