HVAC system replacement and repair in Pelham, AL 35124
Many Pelham subdivisions were built from the 1980s through the 2000s, and the equipment that came with those homes is due for replacement. We replace systems with a load calculation, matched indoor and outdoor parts and ducts that can carry the air.
If your Pelham home still has its original builder system, it is likely near or past the end of its working life. Zeltman Heating & Air replaces those systems with equipment sized by a Manual J load calculation, checks the ductwork before installing and explains your options with prices. We also repair systems that still have life left, and we answer 24/7.
What replacing an original Pelham system should involve
Homes in Pelham's 1980s through 2000s subdivisions, including Ballantrae, often still have equipment the builder chose. Much of it was sized by square footage and installed quickly. After years of Alabama summers, many of these systems are reaching the point where a major failure costs nearly as much as starting over.
A good replacement starts with the house, not the old label. We run a Manual J load calculation using your insulation, windows and layout. That often shows the original system was oversized, which explains short cycling and a clammy feel in summer. A properly sized system runs longer, pulls more moisture and keeps indoor humidity closer to the 30% to 50% range.
We also inspect the ducts. New equipment connected to leaky or undersized ducts never reaches its rated efficiency, and a modern blower can get noisy when the ducts restrict it. Fixing the worst duct problems during the replacement costs far less than coming back for them later.
Current split systems meet SEER2 minimums, 14.3 for most central air, and use A2L refrigerants such as R-454B or R-32. New equipment also comes with a manufacturer parts warranty, which we help you register.

Signs your Pelham system is due for replacement
Major repairs on an older system
A failed compressor or leaking coil on a system past 15 years usually costs too much to justify. We show both prices side by side.
Short cycling and sticky air
An oversized builder unit cools fast and shuts off before it dries the air. Replacement is the time to correct the size.
R-22 equipment still in service
Some older Pelham homes still have R-22 systems. Recharging them is costly because production ended in 2020.
Uneven rooms that never improved
If certain rooms have always been warm, the cause may be duct design. A replacement is the moment to fix it.
Rising bills and frequent service
A system that needs help every season and costs more to run each summer has usually reached the end of its useful life.

I-65 takes us south from our base on 15th Avenue North to Pelham, and US-31 and Pelham Parkway carry us across town. Ballantrae, the neighborhoods near Oak Mountain State Park and the streets in between are all on our usual routes. Neighboring Alabaster and Helena are close by as well.
A replacement starts with a weekday visit to measure the house, check the ducts and look at the existing equipment. You get options with prices in writing, and nothing is ordered until you choose. If your system fails outright in a heat wave, a person answers 24/7, and we work to get you cooling again, even if that means a temporary repair while the new system is scheduled.

Questions from Pelham homeowners
Look at age, refrigerant and the size of the repair. If the system is past 15 years, uses R-22 or needs a compressor or coil, replacement usually wins. If it needs a capacitor or a drain cleaning, repair it. We show you both numbers before you decide.
Not necessarily. We run a Manual J load calculation instead of copying the old size. Many original builder systems were oversized, and a correctly sized replacement can run quieter, control humidity better and cost less to operate.
