No heat? Check the thermostat batteries first

Before paying for a furnace service visit, start with the thermostat. Weak or dead batteries may keep it from calling for heat.

No heat? Check the thermostat batteries first. Depending on the company, a service visit can cost one hundred dollars or more, even when dead batteries are the only issue. Weak batteries can leave the screen blank or faded, and the furnace may never receive the call for heat. Fresh batteries take only a few minutes. Fresh batteries and still no heat? Bernie’s is ready to help. Call 773-900-6248.

Tell Us What Your Furnace Is Doing

Describe the symptom when you call. Have any visible error code and furnace model number ready, and tell us when the problem started and which rooms or units are affected. The technician checks the system, explains the findings and discusses the work required. You receive the repair price before work begins.

Furnace Will Not Start

Thermostat, ignition, electrical and other faults can prevent heating. Tell us whether the thermostat calls for heat and whether the furnace attempts to start.

Furnace Starts, Then Stops

A control may shut the furnace down when it detects a problem. Ignition, airflow and other conditions can cause similar patterns, so inspection comes before a component recommendation.

Cool Air, Noise or Weak Airflow

Explain whether the furnace starts, when the noise occurs and whether airflow has changed throughout the home. Thermostat settings, heating faults and blower conditions can all affect these symptoms.

Component Checks Depend on the Diagnosis

Similar symptoms can have several causes. These component checks help identify the fault before a repair is recommended; the work and timing depend on your equipment, its condition and parts availability.

Igniter Failed

A damaged hot-surface igniter can prevent the burners from lighting. A furnace that tries to start without a flame needs ignition-system testing before an igniter is replaced.

Dirty Flame Sensor

A furnace that lights and shuts down can have a flame-sensing problem. Ignition, airflow and other safety-control conditions can produce similar symptoms. Testing determines whether the sensor needs cleaning, repair or another action.

Blower Motor Issues

Noise or weak airflow can involve motor bearings, a capacitor, the blower wheel or an electronic motor control. The diagnosis determines the repair and parts needed. If the concern requires ductwork service, ask about a specialist referral; Bernie's does not provide duct cleaning, repair, sealing, insulation or installation.

Pressure Switch

A pressure-switch error can involve venting, the inducer, condensate drainage or the control itself. The technician checks the cause of the error before recommending work.

Heat Exchanger Crack

Heat-exchanger concerns need an equipment-specific assessment. Ask about the confirmed fault, the condition of the furnace, parts availability and any applicable warranty before choosing repair or replacement.

Thermostat Problems

Wiring, batteries, settings or communication problems can affect the call for heat. Describe what the thermostat displays so its operation can be checked alongside the furnace.

Preparing for a Chicago Service Visit

Bernie's operates from 3704 N Cicero Ave. When booking, tell us where the equipment is located, which unit is affected and how the technician can reach it. Mention entry requirements and parking arrangements before the visit.

Chicago Bungalows (1910-1940)

Low basement ceilings and equipment near water heaters can affect access. Describe the furnace location and clear a path to it before the visit.

Two-Flats & Three-Flats

Identify the affected unit and whether each apartment has its own furnace. Discuss building access, shared equipment spaces and any need to coordinate with a tenant or property manager.

Greystones & Old Victorians

Homes with radiators may use steam or hot-water boilers instead of a furnace. Tell us which type of system you have so the appropriate service can be discussed.

Downtown Service Note

For downtown locations (Loop, River North, Streeterville, Gold Coast, etc.):

Deposit confirmed when booking

Discuss equipment access, building entry and parking when booking. Ask whether any deposit or parking-related charge applies.

Downtown access and parking can affect service timing. Call to confirm current availability and estimated arrival time for your building.

Equipment and Access Across Chicago

Home layout, renovations and the type of heating system can affect the inspection. Share these details when requesting service; the neighborhood alone does not identify the fault.

Jefferson Park

If a furnace cycles before the home warms up, describe the pattern and any error code. Airflow, ignition and control conditions need diagnosis before work is recommended.

Logan Square

In a renovated greystone, tell us about changes to the equipment or layout. Heating performance and system sizing need assessment rather than assumptions from the building's age.

Portage Park

A bungalow's older furnace may be repairable, but age alone does not establish its condition or remaining life. Review the confirmed fault, parts and proposed repair cost.

Avondale

Two-flats can have tight basement equipment spaces. Identify the affected unit and describe clearance and entry arrangements when you call.

Lincoln Park

For newer controls or high-efficiency equipment, have the model information and any displayed error code ready. Ask about service for your particular system.

Belmont Cragin

Describe the heating problem and ask about the diagnostic charge, proposed repair price and any applicable fee terms before booking.

Frequently Asked Questions

Why is my furnace not heating?

Thermostat, ignition, electrical, airflow and control faults can all prevent heating. Tell us what happens when the thermostat calls for heat. The technician diagnoses the system before recommending a repair.

How much does furnace repair cost in Chicago?

The cost depends on the fault, parts required and work involved. Ask about the diagnostic charge when you book. Bernie's explains the findings and provides the repair price before work begins.

Should I repair or replace my furnace?

Start with a diagnosis. Review the confirmed fault, system condition, previous repairs, proposed cost, parts availability and any applicable equipment warranty. A problem does not by itself establish that the whole furnace needs replacement.

Do you charge extra for downtown Chicago service?

Any downtown deposit or parking-related charge is confirmed when booking and documented in the written estimate. Providing parking may affect that charge.

What's wrong if my furnace is blowing cold air?

Thermostat settings, ignition problems, heating faults or airflow conditions can affect air from the vents. Explain whether the furnace starts and whether the problem affects the whole home; similar symptoms need different repairs.
