Navien Hydronic Air Handler & Hydro-Air Heating Service in Orange County
Aerosphere Electric is factory-trained and certified on Navien, and we service the HVAC side of Navien hydronic systems - the air handler, the hydronic coil, the blower and the controls that turn hot water into warm air in your house. If you have a hydro-air system in Orange County and the air coming out of the registers is cold, the problem is frequently on the air side rather than the heat source, and that is the half of the system we specialize in.

Common Navien Problems We Fix
What actually goes wrong with Navien equipment in Orange County, and what the repair really involves.
Cold air from a hydro-air system
The air handler blower runs but the registers blow cool. Usually an air-locked hydronic coil, a failed circulator feeding the coil, or a zone valve that is not opening - all air-side diagnostics.
Blower motor and ECM module failure
The most common hydro-air repair. The module fails more often than the motor and costs a fraction as much to replace.
Hydronic coil fouling and airflow loss
A dirty coil kills heat transfer. Output drops gradually until the system cannot keep up on a cold night.
Zone valve and thermostat wiring faults
One room that never heats is usually a zone valve or a wiring fault. As a C-10 electrician we trace the wiring instead of guessing at parts.
Air handler condensate and drain issues
In cooling mode the same air handler produces condensate; a blocked drain shows up as water damage before it shows up as an HVAC complaint.
