HVAC

Commercial HVAC upgrades, planned before the next failure plans them for you.

Heating and cooling is commonly the largest load in a commercial building and the most expensive equipment to replace. A planned replacement leaves room to consider heat pumps, right-sizing, controls and the electrical service.

The plan

Start with an equipment register.

List every major unit with its type, capacity, age, refrigerant, service history and the meter that feeds it. The register shows which units are near end of life, which are oversized, and which can be grouped into one project.

Heat pumps

What decides whether a heat pump fits.

Heating load and climate

The building's heating load and the design temperature for the location. Modern cold-climate units are designed for northern winters.

Electrical service

Converting gas heat to electric adds load, so panel and service capacity are checked first.

The tariff

Higher winter electric use changes the bill shape. We model it on the actual rate, including demand.

Local rules

Some cities set building performance standards that favor electrification. See our regulatory guides.

With solar and storage

Plan HVAC with generation, not after it.

A heat pump conversion raises electric load, which changes how much solar the building can use on site, and a battery can hold back the new peak electric heating or cooling creates. Planning them together avoids sizing an array for a building that is about to change.

Questions

Commercial HVAC: common questions

When is the best time to upgrade HVAC?

+

At the end of the equipment's life, planned in advance. A failure in peak season forces a like-for-like replacement at whatever the market charges that week.

Will a heat pump raise my electric bill?

+

Electric use rises when heating moves off gas, and the bill shape changes. Whether total energy cost rises or falls depends on the tariff and the equipment, so we model it on the building's actual rate.

How is an HVAC project funded?

+

Projects are delivered owner-funded, financed or third-party funded. Which structure applies, and who pays, owns the equipment and receives the benefit, is set in the project agreement after underwriting. Utility incentives and, in some states, financing programs such as C-PACE may apply; we confirm what is open in your territory.
