Make Up Air Systems (MUA)

Make Up Air System (MUA) Installation
Simply stated, a make up air unit pulls air into your space from outdoors and conditions it to the indoor temperature, to replace air that's pulled out by your exhaust equipment. Without it, you get back drafting, poor temperature control, negative air pressure and air quality problems. They are also used to provide hallway pressurization in multi family buildings such as condos and apartments to ensure the air and smells from the various suites are not pulled into the hallways.
Weiss Johnson offers a full slate of service, repair and replacement options to ensure your building’s equipment is always operating efficiently and properly.

What Our Customers Say About Us
"The guys were very friendly. They took lots of care and attention when removing the old furnace and replacing it with the new one to not damage anything along the way. Once finished they took the time to explain the operation and go through any questions we had. I would definitely use them again."
- Kyle J.

"This review is for Noel who came to my home to see why our electric air cleaner was not working. He was punctual and super friendly. Found the problem within 15 minutes. Had the part ordered, and 9 days later it literally only took him 3 minutes to replace it for us!"
- Joy H.

"Booking an appointment for a furnace checkup was a very quick and simple phone call. The technician was on time as promised, very knowledgeable and professional. It gave us piece of mind that our 10 year old furnace was in good working order."
- Nicolas L.
