Make-Up Air Unit (MAU)

« Back to Glossary Index

A Make-Up Air Unit (MAU) is an HVAC device specifically designed to bring fresh, conditioned air into a building to replace air that has been expelled or exhausted. Unlike standard ventilation systems, it conditions the incoming air (heating, cooling, humidifying, or dehumidifying it) to maintain indoor air quality and comfort, while also ensuring the pressure balance within the building. These units are often used in spaces like commercial kitchens, manufacturing facilities, and laboratories where large amounts of air are frequently exhausted.

They were great. Came out on a Thursday and looked at my system. Went over all of my options of repairs or replacements. Explained both the advantages and disadvantages of both options in detail so I could make an informed decision. Came back out the following Monday to do the work. Very friendly and knowledgeable staff.

We were in dire situation last last summer when our AC system went off with no repair really feasible. We took some time to shop around despite of awful heat in the house. Johnatan from Paradise Heating and Air is honest, articulate, skillful professional. He offered the best value and cost, the easiest ways to pay, and great service plan. I would recommend everyone to contact Johnatan and Paradise Heating and Air for the AC service.

Daniel Maddox

Jonathan and the guys did a fast and efficient job fixing our ac. Always a worry when it goes out at the start of summer in Alabama. I highly recommend paradise heating and air to fix your ac problem. Communicated arrival time, explained the issue thoroughly, also didn't break the bank! Thanks again paradise!

J. Chapman

Jonathan was great to work with. He came within a couple of hours after I called at around 4pm. and had us operational around 12 the next day (because he didn’t have a motor for my condensor and had to get one the next day). Will definitely use him again.

Nichole Pompey

Johnathan and his son came out quickly and repaired my air conditioner. He explained very clearly what the issue was and temporarily fixed my air while we waited on the warranty part from the manufacturer. Service and hospitality was excellent!

Hector Orozco

Linda Thompson

Jonathan and his helper were awesome. Keeping us informed as to what they were doing as they replaced our heating and air units. They were pleasant to have around and did a great job. They not only left the areas clean they hauled off all the old equipment. We would highly recommended them to everyone.

Kevin

Thank you Paradise Heating and Air for your quick response, great customer service and fair price!

Mary Cavett

Paradise has become our go-to HVAC company. We have used them for several smaller repairs and they always provides a reasonable price and didn’t try to upsell replacing our 30 year old unit before we were ready. Then, when we were finally ready to replace our unit we got quotes from Paradise and several other companies. Paradise was by far the best value not only in terms of price but also unit brand and warranty. We even ran all of the quotes through AI and his came in 1st in terms of value, price and ROI! Great company overall - can always trust them to provide great, high quality work and reasonable prices.

Nancy Hollaway

Our AC was struggling a bit. Had another HVCA company come check it out first. Their recommendation was a whole new replacement unit. Bare minimum a $6000 repair job. Got a second opinion from Jonathan’s company, Paradise. All the unit needed was refrigerant. Saved us thousands !! We would recommend Paradise every day of the week and twice on Sunday.

Jonathan was very professional and knowledgeable, with a great personality. I will be doing business in the future with his company. I immediately signed up with the company’s annual service plan.

Martha Neighbors

Paradise Heating & Air was conscientious about scheduling and doing a thorough job in installation and servicing.

Dwight McPeak

Quick response for broken AC. Found the problem quickly and was able to fix on the same visit. They also recommended some improvements based on another issue I was having. Overall great experience.

I had paradise come out to get me started with their paradise maintenance package, and had them take a look at my attic because we had concerns with our insulation not being adequate. They didn’t try to over sell work I didn’t need, and were honest with what exactly was needed to get us back on track. Techs Jonathan and Matthew came out for the initial inspection and service and came back to do the attic insulation. They were patient and knowledgeable (I ask a lot of questions) and took their time. They found all the places that my system was leaking (out and in) air, fixed them, and then filled the attic. They kept the house clean and were respectful and had great attitudes the entire time. They have definitely earned my business, and I would recommend them to anyone looking for HVAC work. They are AWESOME!

Polly Norris

I honestly cannot tell you just how highly I recommend these folks. Five stars are not enough! They are friendly, professional, very competitively priced and a real pleasure to work with. I've had them out twice, once for a split unit in my sunroom and then today for my main unit and both times they did an exceptional job.

We have had Jonathan and his capable team working on our A/c and Heating for several years. They are punctual, well mannered and reasonably priced. The work they have done including an A/C replacement has always been outstanding.

5 stars! Look nowhere else for all of heating and cooling needs. Jonathan is amazing - experienced, reasonable and reliable. Look nowhere else!

SteelCityScreenPrint

Paradise answered my call late at night and made me an appointment for first thing in the morning and even showed up early. They crawled under my rental house through the dirt and mud to inform me that my landlord had me living in a dangerous environment. He was upfront and honest about everything and let me know the steps I needed to do to get my family out of this situation. No bandaid fixes from these guys, they do things in a professional manner and I couldn’t be more appreciative. Top notch customer service. Highly recommend!

Nae Nae

I’ve used them several times now and they are always quick to respond, very polite and honest. I would highly recommend them.

Rory Chrane

From the first phone call, I was impressed, I spoke to Jennifer and on a follow up call, I spoke to Gracie. Both are related to the owner Jonathan who came out today and gave me a breakdown and an idea of what is needed and proposed how to go about doing a mini split, which I’m excited to get done, so much so that I wanted to give a review, even before the work begins which I’m sure will be excellent. He recommended a good brand Mitsubishi and explained why he chooses them, giving a very detailed explanation. Jonathan was very personable and efficient and I look forward to the job being completed and future business with this company.

Melanie Authement

Honest and kind. Gave incredible price for work completed. Called and was able to come earlier than expected! Cannot recommend enough

John DiOrio

Jon and his team have renewed my faith in the HVAC industry. They service two homes with aging Heating & Cooling systems, and they've gone above & beyond in both cases. From surveying the attics for proper insulation, to accessing the basements and crawl space for any issues that might need to be addressed, I'm confident I'm in good hands with Paradise Heating & Air.

Perry Koonce

Jonathan provided another on-time, courteous and professional annual maintenance service call. Paradise Heating and Air provides great service at a great value.

Ruthie McNeil

I was fortunately able to get an appointment for the next day. Jonathan & Austin were prompt and kept me advised of their arrival. They quickly found the problem with my "heat" and were able to fix it without problems. They were very friendly and professional, and I felt that their pricing was fair and reasonable. Thanks again, Guys! UPDATE: I once again had a very good visit from Paradise Heating & Air - they are very prompt and reliable and do an efficient job - thanks once again! I definitely recommend these nice guys!!!

Jonathan was fantastic to work with!

Jennifer and Gracie were also stellar! Will call them back and recommend to our friends!
