Ductwork, furnace and AC replacement in Bessemer, AL 35020
A lot of Bessemer homes still run the ducts they were built with, and some run systems well past their prime. We help you sort out what to keep, what to fix and what to replace.
Bessemer has early 1900s homes near the historic downtown and 1950s through 1970s ranches in the outer neighborhoods. In both, we often find original ductwork and old furnaces or R-22 air conditioners. Zeltman Heating & Air tests the system, checks gas furnaces for safety and explains repair and replacement options with prices. We cover all of 35020 and answer 24/7.
Old ducts and older systems in Bessemer homes
Near the historic downtown, many Bessemer homes date to the early 1900s. They were heated by other means long before central air existed, so any ductwork came later. In the outer neighborhoods, 1950s through 1970s ranches usually got their ducts when they were built, and in many of those homes the same ducts are still carrying air today.
Old ducts fail quietly. Joints loosen, tape dries out, insulation falls away and sections pull apart in the attic or crawlspace. A system can run for hours and still leave rooms warm because a share of the air never arrives. Before quoting new equipment, we test for leaks and look at the condition of the main trunk and the returns.
The equipment is often old too. We still find air conditioners running R-22, and with R-22 production ended in 2020, a leak means expensive refrigerant. Gas furnaces that have been in service for decades raise a safety question as much as a comfort one, because a cracked heat exchanger or blocked flue can leak carbon monoxide. Homes with gas appliances should have working CO alarms.
When a system is past its prime, we say so plainly. A new system sized with a Manual J calculation, paired with ductwork that has been repaired or replaced, shortens run times and evens out temperatures from room to room.

What we find most in Bessemer homes
Leaky original trunk lines
Decades-old metal trunks and branch runs separate at the joints. Cooled or heated air ends up in the attic or crawlspace instead of the rooms.
Old gas furnaces with safety questions
Rust, soot around the burners and flame rollout are warning signs. We check the heat exchanger and flue and measure CO.
R-22 air conditioners leaking
Recharging an R-22 system is expensive now that the refrigerant is no longer made. A leak is often the point to plan a replacement.
Undersized returns
Older homes often have one small return for the whole house. Low return air strains the blower and starves the coil.
Systems patched for years
Replacement parts on a worn-out unit add up. When repairs come every season, we lay out the replacement cost next to the repair history.

I-459 links Bessemer with Hoover, and Ninth Avenue North is one of the main roads through town, along with the streets around the historic downtown and the Bessemer Hall of History. Hueytown is right next door, and a technician working in one is often close to the other.
Call any hour and a person answers. If the furnace smells odd, the CO alarm sounds or you see soot or scorch marks near the burners, shut the furnace off, get everyone outside if the alarm is going and call 911 or your gas company first, then us. For a planned duct or system replacement, we book a weekday visit to measure and test before quoting.

Questions from Bessemer homeowners
It depends on condition. If the main trunk and most runs are sound, sealing and reconnecting the bad sections may be enough. If the ducts are rusted, crushed or badly undersized for the system, replacement is usually the better long-term fix. We test before recommending either.
Age alone does not make a furnace unsafe, but older units need a careful check. We inspect the heat exchanger for cracks, check the flue and measure carbon monoxide. If we find a dangerous problem, we shut the furnace down and explain why.
If it runs well, keep maintaining it. If it develops a leak or a major failure, replacement usually makes more sense because R-22 production ended in 2020 and recharging is costly. Planning ahead lets you choose the timing instead of replacing in a heat wave.
