Condensing MUAs

Improve air quality while lowering cost

Good indoor air quality starts with proper ventilation. Make-up air (MUA) units play a key role in maintaining a healthier, more comfortable space for occupants.

Upgrading to a high-efficiency condensing MUA unit not only helps you improve air quality but also uses less energy and lowers your operating costs.

Incentives for condensing MUA upgrades

Take advantage of higher incentives for energy efficiency upgrades—it’s the perfect opportunity to improve both your building’s air quality and energy performance.

Limited-time offer: Get incentives up to $21,000† per unit.

Limited-time incentives are available only for projects with purchase orders submitted by Sept. 30, 2025 and installations completed by Oct. 31, 2025.

How do condensing MUAs work?

MUA units take in fresh air from outdoors. The air first passes through filters and dampers to regulate how much air is brought in, removing dust, debris, smoke and other contaminants in the process. It’s then heated with a gas-fired heat exchanger before being blown as tempered air into a space.

Condensing MUA units are similar to non-condensing models, but with much more efficient burners and multiple heat exchangers that extract more waste heat. With less natural gas needed to heat the air, condensing MUAs provide the same level of output for a lower cost.
