Your home should hold one temperature — in every room.
Volta designs HVAC systems the way an engineer would: load calculated, airflow measured, efficiency modeled. We commission every install with data you can read.
Average rating across the systems we installed last quarter.
What we do
Full-system comfort, measured and verified.
AC install & replacement
High-SEER2 systems sized with a Manual J load calc — not a guess off the old unit's nameplate.
Heat pump conversions
Swap gas for an inverter-driven heat pump. We model your bills before you commit to anything.
Smart thermostat setup
ecobee and Nest installs wired to your equipment, geofenced, and tuned to your real schedule.
Indoor air quality
MERV-13 filtration, fresh-air ventilation, and whole-home humidity control that you can actually feel.
Tune-ups & diagnostics
We meter superheat, subcooling, and static pressure on every visit. You get the numbers in writing.
Ductwork & airflow
Sealing, balancing, and redesign so the back bedroom stops running ten degrees off the thermostat.
How it works
We treat your house like an engineering problem.
Most comfort complaints aren't a broken unit — they're an undersized return, a leaky duct run, or a system that was never sized right. We find the real cause, then fix it once.
Diagnose the whole system
We measure airflow, refrigerant charge, and envelope load. The data tells us what's wrong — before we quote.
Engineer the right fit
A correctly sized system, modeled efficiency, and a flat price. No upsell theater, no surprise change orders.
Install & commission
Clean install, vacuum to spec, commissioning report. We don't leave until the readings are in range.

Neighbors who stopped fighting their thermostat.
“They actually measured airflow in every room instead of just selling me a bigger unit. My upstairs is finally the same temp as down.”
“The commissioning report alone sold me. Real numbers, no hand-waving. The heat pump cut my winter bill by a third.”
“Showed up in the window, wore booties, walked me through the readings. First HVAC company that treated my house like an engineering problem.”
Service area
Cooling the metro east side.
Local crews, local response times. If you're within 30 minutes of our Northgate shop, we can usually be out the same day for emergencies.
