Solutions — building managers and public bodies

Mechanical equipment noise: solutions for buildings and public bodies

A rooftop heat pump, chiller or fan is disturbing occupants or neighbours, and the municipality wants answers. Deflection takes charge of the project: acoustic study, manufacturing of panels, enclosures and silencers in Quebec, then installation.

Your situation

What you need to solve

Rooftop equipment disturbing the neighbourhood

Acoustic panels surround the equipment; an enclosure covers it completely.

A complaint or notice from the municipality

An acoustic study measures sound levels, identifies the sources and sizes the solution.

Vibration felt inside the building

Rails and spring isolators under the equipment stop transmission to the structure.

A project to hand over completely

Consultation, study, supply and installation in a single turnkey project.

Frequently asked questions

Building managers and public bodies

How do I reduce noise from a rooftop heat pump or chiller?

There are two solutions, depending on the noise level to be reached: acoustic panels surrounding the equipment, or an acoustic enclosure covering it completely. Both are made in Quebec by Deflection.

What should I do after a noise complaint from the municipality?

The first step is an acoustic study: it measures sound levels, identifies the sources and sizes the solution. Deflection can take charge of the whole project, from the study to installation.

Does Deflection offer installation?

Yes. Installation is offered as a turnkey option, carried out by RBQ-certified technicians, with flexible schedules (day, evening or weekend) to suit your site constraints.

What are your delivery times?

Acoustic panels, enclosures, silencers and anti-vibration rails are made in Quebec, which allows short lead times. For distributed products, lead time depends on inventory. Contact us with the details of your project: we reply within 24-48 business hours.
