AC repair, zoning and heating service in Hoover, AL 35244
Hoover is the largest suburb in the metro, and the question we hear most here is simple: why is it so hot upstairs? We fix the airflow, the ducts and the equipment behind it.
Two-story homes built in the 1980s, 1990s and 2000s make up much of Hoover, and many run separate upstairs and downstairs systems. Zeltman Heating & Air repairs and replaces those systems, rebalances airflow and adds zoning where it helps, across 35244 and the rest of Hoover in both Jefferson and Shelby counties. We answer 24/7.
Why second floors in Hoover run hot
Heat rises, but that is only part of the story in a Hoover two-story. The upstairs system usually sits in an attic that bakes all afternoon, with ducts running across that same hot space. The bedrooms sit right under the roof. By late afternoon in July, the upstairs unit is fighting heat from above and from the floor below.
Many homes from the 1980s through the 2000s were built with modest return air upstairs, sometimes a single grille in the hallway. With bedroom doors closed, those rooms cannot push air back to the system, so supply airflow drops and they warm up. A larger return or jumper ducts between rooms can change that more than new equipment would.
Sizing plays a part too. Some upstairs units were picked by rule of thumb and are either too small for the heat load or so oversized that they short cycle and leave the air sticky. When we replace a Hoover system, we run a Manual J load calculation for each floor. Where one system serves both floors, zoning with motorized dampers can split the house into areas that each get their own thermostat.
Around Ross Bridge, Lake Cyrus and the neighborhoods off Valleydale Road, many of these homes are reaching their first or second replacement. That is a good moment to fix the airflow problems the original install left behind.
Hoover heating and cooling problems we fix most
Bedrooms that never reach the set point
When the hallway thermostat reads 74 and the back bedroom reads 79, the cause is usually return air, duct leakage or a weak upstairs blower.
Two thermostats working against each other
In homes with one system per floor, a cranked-down upstairs unit can overcool the stairwell and confuse the downstairs thermostat. Settings and airflow both need a look.
Attic units leaking water
Upstairs air handlers sit over finished ceilings. A clogged condensate line or rusted pan can stain drywall quickly, so we check the float switch on every visit.
Builder heat pumps nearing retirement
Heat pumps installed when these subdivisions were new are now old enough for compressor and reversing valve failures.
Sticky air after a short run
Oversized systems cool the air fast and shut off before removing moisture. Indoor humidity above 60% is a sign the system is not running long enough.

Valleydale Road and John Hawkins Parkway take us into the subdivisions spread across the rest of town. Hoover calls are routine for us, so a technician is often working somewhere nearby already.
Hoover crosses the line between Jefferson and Shelby counties, and that makes no difference to how we serve it. Call any hour and a person answers. Describe what each system is doing and which floor is affected, and we will tell you what to check and when we can arrive. For zoning and airflow projects, we book an unhurried visit to measure room by room. Homes near the edge of town in Vestavia Hills and Pelham are on the same routes.

Questions from Hoover homeowners
The upstairs system works under a hot roof with ducts in the attic, and many Hoover two-stories have small returns upstairs. Leaky ducts, closed bedroom doors and an undersized or oversized unit make it worse. We measure airflow and temperature in each room to find which of these is the cause.
It can be, if one system serves both floors and the temperature gap is large. Zoning uses motorized dampers and a thermostat for each area. It works only when the ducts and the equipment can handle it, so we check static pressure and sizing first.
Yes. We cover all of Hoover, including 35244, Ross Bridge, Lake Cyrus, the area around the Riverchase Galleria and the subdivisions off Valleydale Road and John Hawkins Parkway, whichever county your address falls in.
Not necessarily. If both are the same age and one has already failed, the other often follows within a few years. Replacing them together can make sense, but doing one now is fine. We test both and tell you how much life each one has left.
The DOE suggests about 78°F when you are home in summer. In a two-story, set the upstairs a degree or two lower than downstairs in the evening, and avoid big setbacks that make the attic system work all night to recover.
