No heat?
Find the cause.
A complete heating-system diagnostic for ignition, controls, airflow, venting and furnace performance—followed by a clear repair option.
Secure application through Abode Financial. Get a credit decision in seconds.

Furnace repair starts with the full heating system.
A furnace that will not start, shuts down early, blows weakly or makes a new sound can have a thermostat, power, control, ignition, fuel, venting or airflow problem. The symptom alone does not identify the failed component.
Our diagnostic records the reported issue and checks the operating sequence before a repair is proposed. You receive the finding, intended repair and price for review before non-emergency work begins.
If there is a suspected gas leak, carbon-monoxide alarm, smoke or immediate safety risk, leave the affected area and contact emergency services or the utility first. Online booking is not an emergency-response substitute.
New system vs. keeping what you have.
Keep the current system
Good repair work starts
with the whole system.
Your air conditioner is more than the unit outside. Scroll through the system to see how each component works—and where our technicians look when comfort breaks down.
Condenser unit
The compressor and outdoor coil release heat collected inside your home. We test electrical components, refrigerant pressures, the fan motor and coil condition before recommending a repair.
- Warm air from vents
- Buzzing or hard starts
- Outdoor unit not running
Evaporator coil + blower
The cold evaporator coil absorbs indoor heat while the blower moves conditioned air through the home. Ice, restricted airflow or a tired motor can quickly reduce comfort.
- Frozen coil or water leaks
- Weak airflow
- Long cooling cycles
Ductwork + airflow
Even healthy equipment cannot perform through leaking, restricted or poorly balanced ducts. We check temperature split, static pressure, filtration and the air path—not only the machine.
- Hot and cold rooms
- Noisy registers
- High energy use
Thermostat + controls
Your thermostat, sensors and low-voltage controls tell every component when to run. A clean diagnosis separates a control problem from an expensive equipment problem.
- Blank or inaccurate display
- Short cycling
- System ignores settings

1-833-700-4822 →Why is my furnace running but not heating?
Possible causes include controls, ignition, fuel delivery, limit operation, airflow restrictions or a thermostat issue. A safe diagnosis requires observing the operating sequence.
Should I reset the furnace repeatedly?
No. One check of the thermostat, filter and normal power switch may be reasonable, but repeated resets can hide a fault or create risk. Arrange service when the problem returns.
Can I compare repair and replacement?
Yes. When equipment condition or repair cost makes replacement relevant, you can compare that option using the same documented system information.
