California-based Axiom Cloud has added autonomous HVAC optimisation to its AI refrigeration platform.

The HVAC optimisation module follows field validation, marking the company’s first expansion into an asset class beyond refrigeration. The module autonomously identifies and resolves HVAC inefficiencies across rooftop unit fleets and implements fixes directly through existing building management systems and controllers without the need for manual intervention.

HVAC directly impacts occupant comfort, which can positively or negatively affect business metrics such as customer traffic, employee productivity and revenue. In addition, HVAC is one of the largest energy uses in commercial buildings, and rooftop units are a major source of avoidable waste. In retail grocery and convenience operations, those costs compound quickly and much of the waste is preventable.

For example, rooftop units commonly run at full capacity during off-hours when a building is empty, conditioning and replacing air as if the building was fully occupied. In buildings that rely on multiple rooftop units, it is not uncommon for adjacent units to work against each other, one heating and one cooling at the same time, consuming double the energy without changing the space temperature. These kinds of configuration failures can persist for months or years without triggering an alarm, silently driving up utility costs across an entire fleet of locations.

Axiom’s module identifies these conditions across a user’s portfolio, identifies units that are not working as expected, quantifies the financial impact of each problem, and resolves those that can be addressed remotely without the need for a technician to go on the roof.

“The waste hiding in commercial HVAC systems is not a technical problem, it is an operational problem,” said Amrit Robbins, CEO of Axiom Cloud. “Nobody is watching, so unit failures or egregious energy issues can silently persist for months or years without anyone noticing. Over the past year, we have demonstrated significant operational improvements and cost savings for our existing customers. The platform that is already optimising refrigeration across their enterprise covers this too; the same approach that works for refrigeration now works for HVAC.”

For existing Axiom users, the expansion means the platform already embedded in their facilities now covers HVAC with no new integration, no new vendor relationship and no new operational burden. The module has been in active beta across 17 facilities and 40 rooftop units, backed by a platform that has logged over 3400 system-years of HVAC operating data across all Axiom sites and customers before general availability. The module deploys entirely through software, connecting to systems already in place at each facility.

Trained on over 2000 site-years of field data and 124,000 hand-labelled system anomalies, Axiom’s AI-powered service delivers measurable business outcomes rather than just data visibility. The platform integrates seamlessly with existing infrastructure and is listed by the EPA and Carb as an indirect automatic leak detection provider.
