How quickly can you reach Blackhawk from San Ramon?

Fast. Blackhawk borders Danville and San Ramon, so we are practically next door. Alamo is right there too. It is one of our quickest routes, which makes same-week scheduling easy even in the summer rush.

Half my house cools and half does not. What is going on?

On a multi-zone Blackhawk Carrier system, one half lagging almost always means a failed zone damper or zone board, not a failed AC. We test the zoning first so you are not quoted a compressor when a damper actuator is the real issue.

The Infinity board is expensive. Is it worth repairing?

If the rest of the system is sound, yes, even at the board price. If the equipment is near end of life we put both repair and replacement in writing so you can compare. We do not push you one direction over the other.

Carrier in Blackhawk

Carrier heating and cooling in Blackhawk.

Blackhawk sits right up against Mount Diablo, fully inland, and it gets hot in summer. The homes are large gated custom estates, mostly built from the 1980s through the 2000s, and they run multiple Carrier systems with extensive zoning. The combination of high cooling load and complex zoning is exactly what Infinity equipment is built for, and that is what we mostly find here.

A typical Blackhawk house has two or three Carrier systems, one or more dedicated to the upstairs bedroom wing that takes the afternoon heat. When a zone falls behind on a 100-degree day, the usual culprit is a zone damper, a zone board, or a charge issue on a long line set, not the compressor. We trace the full zoning layout before we point at the equipment.

Carrier and Bryant are the same equipment under different badges, and on these custom builds we see both. The parts are available and the build is good. The Infinity communicating boards and the variable-speed ECM modules are the costly parts, so on a no-cool call in peak heat I confirm the exact fault on the meter before I quote a board.

Common repairs we do

What we close on the truck.

Stuck zone damper in upstairs bedroom wing. On hot afternoons a stuck zone damper leaves the upstairs bedrooms warm while the main level stays comfortable. The actuator motor fails or the zone board loses the signal. We test both and replace the failed part. It is a much smaller repair than the symptom suggests.
Infinity variable-speed ECM blower failure. The variable-speed blower module on a Blackhawk Infinity air handler quits and airflow drops or stops, which a large two-story load feels right away. The module costs real money, so I verify the motor and the control signal before I replace it, and I check the harness for a simpler cause first.
Low charge on long refrigerant runs. These big estates have long line sets to the outdoor units, and a slow leak shows up as weak cooling when the heat peaks. We measure superheat and subcooling, locate the actual leak rather than topping off, and repair it so the charge holds through the summer.
