Heat pump installation in Birmingham, AL
A heat pump is the only heating and cooling system in a large share of Alabama homes, so getting it right shows up on every power bill. We size it to your house, match it to your ducts and set it up for our cold snaps.
A heat pump installation starts with a Manual J load calculation, a look at the ductwork and a decision on backup heat. Today's split heat pumps run on A2L refrigerant, R-454B or R-32 in most lines, and carry SEER2 and HSPF2 ratings. Zeltman Heating & Air explains each option in plain terms and gives you the full installed price before any work is scheduled.
What a well-planned heat pump installation looks like
A heat pump moves heat instead of making it, so in mild weather it delivers far more heat than the electricity it uses. Birmingham winters are mostly mild with short, sharp cold snaps, which suits a heat pump well. The installation choices decide how it behaves on the few nights that drop into the 20s or the teens.
The capacity decision rests on an ACCA Manual J load calculation. It weighs your insulation, windows, orientation and floor area, not the tonnage printed on the old unit. An oversized heat pump short cycles in summer and leaves the house clammy, while an undersized one leans on backup heat every winter morning.
Next is the balance point, the outdoor temperature where the heat pump alone can no longer replace the heat the house is losing. Below it, backup heat makes up the difference. We size the electric strips, or pair the heat pump with a gas furnace as a dual fuel system, so the backup covers the gap without waste.
The equipment itself has changed. Current split heat pumps run on the newer A2L refrigerants, which call for matched coils, careful line set work and, in some air handlers, built-in leak sensors. Each model carries a SEER2 cooling score and an HSPF2 heating score, and we explain what those mean for your bills instead of pushing the highest one.
What we check before quoting a heat pump
- Manual J load calculation for heating and cooling
- Duct size, static pressure and return air capacity
- Electrical panel capacity and breaker sizing for the strips
- Existing line set size, length and condition
- Pad location, drainage and room for winter defrost water
- Air handler or furnace compatibility with A2L refrigerant
- Backup heat type and the balance point for your house
- Thermostat compatibility with heat pump staging
What heat pump installation costs in Birmingham
$6,380 to $13,940
A matched heat pump and air handler for a single-story ranch with usable ducts sits near the lower end. Variable-speed equipment, larger homes, duct changes and electrical upgrades push the price up. Your written price covers equipment, labor and startup, and you have it before anything is scheduled.

- Size and staging
- Single-stage, two-stage and variable-speed heat pumps differ in price, comfort and how well they hold heat output in cold weather.
- Indoor equipment
- Replacing the air handler along with the outdoor unit costs more than an outdoor-only swap, but a matched pair is what the efficiency figures assume.
- Ductwork condition
- Undersized returns or leaky attic ducts may need work so the new system can move the air it was designed for.
- Electrical work
- Some older panels need a new breaker, a disconnect or wiring upgrades to carry the heat pump and its strips.
- Line set and access
- A long or damaged line set, a steep lot or an attic air handler adds labor and materials.
How a heat pump installation goes, start to finish
Home visit and load calculation
We take room measurements, open the panel, check the ducts and ask which rooms never feel right.
Options and a written price
You get two or three equipment choices with their SEER2 and HSPF2 figures and the full installed price for each.
Installation day
Most replacements take a day. We set the pad, replace or flush the line set, install the indoor unit and wire the controls.
Vacuum, charge and startup
We pull a deep vacuum, release and weigh in the refrigerant, then test heating, cooling and a forced defrost.
Walkthrough and registration
We show you the thermostat settings, the filter and what normal defrost looks like, and help register the manufacturer parts warranty.
When a new heat pump makes sense
Your heat pump is 12 to 15 years old or more
Units that age often need a reversing valve or compressor, and that repair can cost a large share of a new system.
It still runs on R-22
Recharging R-22 is expensive since production ended in 2020, so any leak repair on those systems deserves a hard look.
You heat with electric strips alone
Replacing straight electric heat with a heat pump usually cuts heating costs, with the strips kept for backup.
Comfort has slipped
Hot upstairs rooms, clammy summer air or long winter run times can point to an aging or poorly sized system.
Your gas furnace and AC are both due
A heat pump with strip or furnace backup can replace both, depending on your gas and electric costs.
Bills keep climbing
If energy use has grown year over year with no change in habits, the system may be losing efficiency.
Heat pump installation across the Birmingham metro
Shelby County subdivisions in Helena, Chelsea and Pelham are full of builder-grade heat pumps reaching the 12 to 18 year mark, many in two-story homes with a separate system upstairs. Replacing both at once can simplify scheduling. We still size each one on its own, because the upstairs and downstairs loads are rarely equal.
In older homes in Crestwood, Huffman and Center Point, the existing ducts often run through a crawlspace or a low attic and were designed for a smaller, older system. We check them before quoting, since a new heat pump on undersized ducts never reaches its rated efficiency. Installs are scheduled from our base on 15th Avenue North at a time that works for your household.
Areas we cover most often
We repair and replace equipment from these manufacturers, plus most other makes.
Questions about heat pump installation in Birmingham
It depends on insulation, windows, layout and duct condition, not just floor area. We run a Manual J load calculation to find the heating and cooling load, then pick equipment that covers it without oversizing. Copying the old unit's tonnage often repeats an old mistake.
Yes. Since the EPA transition, new split heat pumps ship with R-454B or R-32 instead of R-410A, which can no longer go into new installs. The indoor coil and outdoor unit must be matched for the new refrigerant, which affects whether existing indoor equipment can stay.
SEER2 is the cooling efficiency score and HSPF2 is the heating score, both from the newer federal test method. A higher figure means less electricity for the same comfort. In Birmingham, cooling hours outnumber heating hours, so we weigh both figures rather than chasing the top heating number.
Sometimes, if it is young, compatible with the new refrigerant and matched to the outdoor unit. Often the old air handler is as old as the outdoor unit and not approved for A2L refrigerant, so replacing both gives a matched system that can deliver its rated efficiency.
Most straight replacements take one full day. Jobs that add ductwork, electrical upgrades or a new line set through finished walls can take a second day. The written price includes the planned install days, so you can arrange your week.
It can be in two-story homes, homes with humidity complaints and houses where one room never matches the rest. Variable-speed units run longer at low speed, which pulls more moisture in summer and holds steadier heat in winter. For a small, simple ranch, two-stage equipment is often enough.
