About Bessemer
HVAC service in Bessemer means tackling decades of retrofits and aging infrastructure. Solidly constructed homes from the pre-1960 era through modern development line the streets of Jonesboro, Pipe Shop, and the 19th Street downtown area — many originally built without central air and retrofitted over the years. Gas furnace safety is a particular concern in older Bessemer homes, where heat exchangers have had decades to develop cracks.
The Marvel City — Where Heat Pumps Are The Right Answer
Bessemer has more heat pump installations per capita than any other area we serve, and there is a reason: the 1960s-1980s housing stock in Jonesboro and Western Hills was mostly built without natural gas service, which means every heating upgrade is either electric strip heat or a heat pump — and for an Alabama climate with winter lows in the low 30s, a heat pump wins every time on operating cost. What we see over and over in Bessemer is a homeowner replacing an aging electric-only unit with a modern 16-SEER heat pump and cutting their winter electric bill by thirty to forty percent. That is not a sales pitch, it is a math problem, and the math favors heat pumps for almost every home in Bessemer.
95-Degree Days And Efficiency Drop
Bessemer runs about one to two degrees hotter than Gardendale in the summer, and that matters more than it sounds. Every SEER rating is measured at 95 degrees ambient — once the outdoor temperature climbs above 95, efficiency drops sharply, and on a 100-degree Bessemer afternoon, a nominally 16-SEER system may be delivering 12 SEER of real cooling. The fix is not to oversize. The fix is to install systems that handle high ambient conditions well, which usually means variable-speed compressors, properly sized condenser coils, and shade or ventilation around the outdoor unit. We route new Bessemer installs around the hottest exposures on the property, and we check for shade patterns before we pour a new pad.
Gas Furnace Safety — The Hwy 150 And Jonesboro Problem
The Bessemer homes that do have gas heat are mostly older, and they mostly have gas furnaces that are between twenty and forty years old. At that age, the heat exchanger is the thing you worry about. Cracked heat exchangers leak carbon monoxide into the living space, and they are not always visible without a camera inspection. Every fall, we run a furnace safety check that includes combustion analysis, CO testing at the supply register, and visual inspection of the exchanger with a borescope. If we find a crack, we tell you plainly, we shut the unit down, and we give you replacement options. We do not upsell furnace replacements we cannot see a reason for — but we will not let a family run a cracked exchanger through an Alabama winter either.
| Era | Style & Size | Common HVAC Issues |
|---|---|---|
| Pre-1960 | Jonesboro / historic core, retrofitted central air, 900–1,400 sq ft | Aging gas furnaces, window-to-central conversions, limited electrical capacity |
| 1960s–1980s | Western Hills / Academy Dr, brick and frame, 1,100–1,800 sq ft | Original ductwork deterioration, R-22 systems, thermostat upgrades needed |
| 1990s–present | Varied infill, 1,200–2,200 sq ft | Builder-grade aging, crawl space moisture, heat pump conversions from electric strip |

Field Notes from Bessemer
Heat pump replacement, Bessemer Pointe subdivision
“Twelve-year-old Goodman 14-SEER heat pump with a failing scroll compressor. Quoted a 16-SEER2 Trane XR variable-speed replacement with a matched AHRI-certified coil. Alabama Power rebate verified and applied. Old refrigerant recovered per EPA 608.”

Cracked heat exchanger, Jonesboro older frame home
“1970s-era 80% gas furnace. Borescope inspection revealed a hairline crack at the secondary exchanger. CO at the supply register tested at 85 ppm. Unit shut down immediately, red-tagged, replacement options presented. Homeowner chose a Rheem 90% two-stage.”
— Service note, Bessemer
Evaporator coil corrosion, Western Hills 1980s ranch
“R-22 system losing charge. Electronic detection + UV dye located formicary corrosion at the evap. Given current R-22 reclaimed pricing and the age of the outdoor unit, full system replacement presented as the better value option. Homeowner chose replacement.”

Mini-split retrofit, Abbott neighborhood 1940s bungalow
“Historic home with no existing ductwork and window units. Installed a Fujitsu 2-zone ductless system, one head in the main living area and one in the bedroom. Line set routed through a single wall chase.”
— Service note, Bessemer
Contactor and capacitor combo replacement, Raimund area
“No-cool service call. Contactor contacts heavily pitted and capacitor reading 18/3 on a 35/5-rated dual run. Replaced both. Measured amp draw within spec at startup. Documented the fix and added a photo to the maintenance record.”
— Service note, Bessemer
Electric strip heat to heat pump conversion, Western Hills
“Homeowner replacing a 1980s electric air handler. Installed a 16-SEER2 heat pump with variable-speed air handler and 10 kW auxiliary strip for emergency heat only. Winter operating cost dropped by about one-third based on the following month’s Alabama Power bill.”
— Service note, Bessemer
Condenser fan motor failure, Academy Drive
“Outdoor unit running, compressor tripping on high-pressure safety. Fan motor shorted to ground. Replaced with an OEM-matched PSC motor, verified capacitor on the new motor, cleaned the coil, and restarted under load. Head pressure back within spec.”
