Furnace Repair & Replacement in Birmingham, AL

A furnace in Alabama sits idle most of the year, then gets asked to work on the coldest night of the winter. That is usually when they fail. Precision Services repairs and replaces gas and electric furnaces across Birmingham, McCalla, Bessemer and Hueytown, on every major brand, whether we installed it or not. We are licensed for gas work, our line answers 24/7, and you get an upfront price before anything starts.

Furnace Repair in Birmingham

Most furnace calls come down to a part, not the whole system. The ones we run most often: no heat at all, a furnace that starts and then shuts off after a minute or two, a blower that runs without ever warming the house, ignition and pilot faults, and thermostats that never call for heat in the first place.

Because our crews are in-house and multi-trade, one call covers it. If the fault turns out to be electrical, such as a tripped breaker or a bad limit circuit, that is the same crew. If you heat with a heat pump rather than a furnace, see our HVAC services instead.

No Heat? Check These Before You Call

Gas Furnace Safety: Cracked Heat Exchangers and Gas Leaks

If you smell gas, leave the house first and call from outside. Do not flip switches on or off on your way out. Call your gas utility, then call us.

The heat exchanger is the metal wall between the burner flame and the air blown into your house. When it cracks, combustion gases, including carbon monoxide, can reach that air. A cracked heat exchanger is a safety problem rather than a comfort problem, and a furnace with one should be shut down until it is repaired or replaced.

Warning signs worth taking seriously: a burner flame that is yellow and lazy rather than crisp and blue, soot around the furnace, a strong smell when the heat runs, or people in the house getting headaches or feeling unwell only when the heat is on. Every home with gas heat should have working carbon monoxide detectors.

We are licensed for gas work and we do not cut corners on it. If we find a cracked heat exchanger, we show you what we found and give you both the repair and the replacement numbers.

Furnace Problems We Repair

• Ignition and flame sensor faults. The most common failures on a modern furnace. A dirty flame sensor will light the burner and then shut it down seconds later.
• Short cycling. The furnace starts, runs briefly, and stops. Usually airflow, a dirty flame sensor, or a safety switch doing its job.
• Blower and motor problems. Air that never gets warm, or no air movement at all.
• Limit and pressure switches that trip and lock the furnace out.
• Condensate problems on high-efficiency furnaces, where a blocked drain shuts the system down.
• Cracked heat exchangers, handled as the safety issue they are.
• Thermostat and control faults, including smart thermostats wired wrong for the system they are running.

Repair or Replace Your Furnace?

Our rule of thumb: under 10 years old, repair it. Past 15 with a major failure, especially a cracked heat exchanger or a failed blower assembly, replacement usually wins. In between, it comes down to the repair cost against the condition of the rest of the unit. We show you both numbers and let you decide, rather than pushing a system you do not need yet.

Furnaces generally last around 15 to 20 years, and often longer here simply because they run so little. That cuts both ways: a furnace in Alabama can be old and still healthy, or old and quietly unsafe. The heat exchanger is what decides which. Financing is available through Wells Fargo.

Furnace Installation & Replacement

When a furnace is past saving, we size the replacement to the house rather than matching whatever was there before. We will also tell you honestly whether a furnace is still the right answer for your home. Most houses around Birmingham do well on a heat pump, some do better on gas, and some are best on a dual-fuel setup that uses both. We will tell you which one you have, and what each actually costs to run here rather than a national average. For heat pumps and whole-system replacements, see our HVAC services.

Come summer it is the other half of the same system. If the cooling side is the problem, see our AC repair page.

Emergency Heating Service, 24/7

No heat on the coldest night of the year is a real emergency, especially with young kids, elderly family or pets in the house. Our line answers 24/7, and because our crews are in-house, one call gets you the diagnosis and the repair. Call (205) 807-6319.

A Fall Tune-Up Prevents Most of This

Nearly every no-heat call we run in January could have been caught in October. A heating tune-up covers the burners and flame sensor, the heat exchanger inspection that matters most on gas heat, the blower, the electrical connections, the filter and the safety controls. Book it before the first cold snap, when everyone calls at once. See our HVAC maintenance options.
