Warning Signs

Furnace Symptoms That Need Diagnosis

These symptoms can come from controls, airflow, electrical, ignition, fuel, venting, or equipment concerns. A diagnosis identifies the relevant cause:

Furnace does not start or does not produce heat
Cold air continues after the system should be heating
Heating starts and stops repeatedly without reaching the setpoint
Unusual ignition, blower, rattling, or grinding noises
Breaker trips, controls reset, or the thermostat does not call for heat
Carbon-monoxide alarm, gas odor, smoke, or a burning smell
Safety Comes First

What Should I Do If a Carbon-Monoxide Alarm Sounds or I Smell Gas?

Leave the building and call emergency authorities from outside. If a carbon-monoxide alarm sounds or anyone has possible carbon-monoxide symptoms, go outside, call 911 or the fire department, and do not re-enter until responders say it is safe. If you smell gas, leave without operating switches or creating a flame, then call 911, the fire department, or the gas utility from outside. Furnace booking comes after the property is cleared for service.

This emergency guidance follows the U.S. Consumer Product Safety Commission carbon-monoxide guidance and PHMSA natural-gas emergency guidance.

Identify the System

Gas Furnace, Electric Furnace, Heat Pump, or Dual Fuel?

Florida homes can use different heating arrangements. Identifying the installed equipment prevents an AC, heat-pump, or auxiliary-heat problem from being mislabeled as a furnace problem.

1Gas Furnace
Uses fuel, combustion, venting, ignition, a heat exchanger, and a blower. Fuel and combustion concerns require professional service.
2Electric Furnace
Uses electric heating elements and a blower. Breakers, controls, elements, sequencing, and airflow can affect operation.
3Heat Pump
Transfers heat and normally provides both cooling and heating. Thermostat, outdoor-unit, refrigerant-side, defrost, electrical, and airflow clues can overlap.
4Dual Fuel
Combines a heat pump with a furnace. Controls determine when each heating source operates, so both systems and their coordination may need review.

Common Questions

Frequently Asked Questions: Furnace Repair & Installation

1Who repairs furnaces in St. Petersburg and Pinellas County?

Hales AC diagnoses and services gas and electric furnaces for St. Petersburg, Pinellas County, and nearby Tampa Bay homes. The technician identifies the heating equipment, checks the reported no-heat, ignition, airflow, electrical, control, or safety concern, and provides written options before approved work begins.

2What can I safely check before scheduling furnace repair?

Confirm that the thermostat is set to heat and above room temperature, check the furnace service switch and the correct breaker, inspect the filter, and make sure supply and return openings are not blocked. Do not open a combustion cabinet, relight equipment unless the manufacturer instructions permit it, or bypass a safety control.

3What affects furnace repair cost?

Cost depends on the heating equipment and fuel type, the diagnosed component or safety concern, access, parts, controls, venting, electrical or blower work, and whether separate duct, permit, or replacement work is required. Hales AC provides written options for the diagnosed scope before approved work begins.

4Should I repair or replace my furnace?

Repair may be practical when the diagnosed problem is isolated, the remaining components can operate safely, and compatible parts are available. Replacement deserves comparison when failures repeat, an unsafe heat-exchanger or venting condition cannot be corrected reasonably, parts are unavailable, or the furnace must be coordinated with broader cooling, airflow, electrical, or duct work.

5Is a furnace or heat pump a better fit for a Pinellas County home?

The right choice depends on the existing fuel and venting, electrical capacity, ductwork, home load, comfort priorities, cooling-equipment timing, and operating assumptions. A heat pump moves heat and can provide heating and cooling; a dual-fuel system combines a heat pump with a furnace. Hales AC compares the approved system scope rather than applying one answer to every home.

6How often should a furnace be inspected?

ENERGY STAR and the U.S. Consumer Product Safety Commission advise an annual professional heating-system check, preferably before the heating season. The applicable inspection can include controls, airflow, filters, fuel or electrical connections, combustion, venting, and the heat exchanger based on the equipment in the home.
