Heat pump and AC replacement in Trussville, AL 35173
Trussville has grown fast, and the systems that went into its newer subdivisions are reaching the age where they start to fail. We help you decide what to repair, what to replace and when.
Most of our Trussville calls come from two-story homes in the newer subdivisions, where builder-installed heat pumps and air conditioners are aging out. Zeltman Heating & Air diagnoses the failure, tells you plainly whether the system is worth repairing and quotes a correctly sized replacement when it is not. We also work on the historic Cahaba Project homes, and we answer 24/7.
Builder systems in Trussville's newer subdivisions
Trussville's large newer subdivisions filled in quickly, and many homes went up with the same builder-grade equipment. That made sense on day one. Now a lot of those systems are aging out together, and neighbors often see failures within a few seasons of each other: a heat pump that ices over and stays that way, an upstairs condenser with a leaking coil, or a blower motor that quits in July.
A failure on an aging builder system raises a fair question. Is this the first of many repairs, or a one-time fix? We weigh the age, the refrigerant, how often the system has needed help and what the repair costs next to a replacement. If a capacitor fails on a healthy unit, we replace it. If an older system needs a compressor, we lay out the replacement numbers instead.
The other side of Trussville is much older. The 1930s Cahaba Project homes in the historic district were built long before central air. Some still have very limited ductwork, and many have been retrofitted over the years. For those houses, ductless mini-splits or carefully planned duct runs often work better than forcing a large system into a small attic.
Signs a Trussville builder system is wearing out
Heat pumps that ice up and stay iced
A failed defrost control, a bad sensor or a low charge leaves the outdoor coil frozen. The house loses heat while the unit struggles.
Repeat refrigerant top-offs
If the system needs refrigerant every summer, there is a leak, often in an aging indoor coil. Topping it off only delays the bill.
Blower motors failing in summer
Indoor blower motors on builder systems work hard in attic heat. Weak motors show up as low airflow before they stop.
Power bills climbing with no change in use
An aging system loses efficiency as coils get dirty and parts wear. Next to a new unit meeting the current 14.3 SEER2 minimum, the gap can be large.
Upstairs units losing ground
When the second-floor system can no longer hold the set point on hot afternoons, worn parts and leaky attic ducts are usually both involved.

Questions from Trussville homeowners
It depends on the failure and the age. A capacitor, contactor or defrost board on a healthy system is worth fixing. A failed compressor or a leaking coil on an older unit usually points toward replacement. We price both so you can decide with real numbers.
Yes. Those 1930s homes were built without central air, so ductwork is often limited or retrofitted. We repair existing systems and often suggest ductless mini-splits or carefully planned duct runs that fit the house without major changes.
Yes. We cover all of Trussville, AL 35173, in both Jefferson and St. Clair counties, including the historic district, the homes along Main Street, the Trussville Springs area and the subdivisions off Chalkville Mountain Road.
New residential split systems now use A2L refrigerants such as R-454B or R-32 under the EPA's 2025 transition. If your current system runs on R-410A, it can still be repaired, but any replacement will use the newer refrigerant and matching equipment.
Some frost is normal, and the unit should clear it during a defrost cycle. If ice builds up and stays, the defrost control, a sensor, low refrigerant or a stuck reversing valve may be the cause. Switch to emergency heat if you have it and call us.
