Make-up air, or MUA, refers to fresh outdoor air that is brought into a building to replace the air that has been removed by exhaust systems. This helps maintain proper air pressure balance inside the space, improves indoor air quality, and ensures efficient operation of HVAC systems. It is commonly used in commercial kitchens, industrial facilities, and other areas where large amounts of air are regularly exhausted.

just left us a 5 star review
Great, fast and professional service always!!
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.
Paradise Heating and Air was great to work with—professional, on time, and very thorough. They communicated clearly throughout the entire process and were upfront about pricing and exactly what they discovered was wrong. I’m very pleased with their service and will definitely use them again. Being on time was a huge plus as well!
Always on time and very well please explain everything that they did
Excellent service, on a Sunday, highly recommend :)
Very professional and knowledgeable. No need to look over their shoulder. Very satisfied with their work.
I had my new unit installed about a week ago. Johnathan was the best. It was effortless , perfect workmanship , on time. Explained everything! Thank you Paradise !! FIRST RATE. TOOK CARE OF ME ASAP. WILL USE IN FUTURE FOR NEW UNIT
Great service - always on time and very professional.
Excellent company! Jonathan and Matt were professional, friendly, and extremely efficient. They had my HVAC system replaced in 4 hours! If my other unit ever bites the dust, they will be the ones I call for a new one!! I highly recommend them.
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.
Johnathan was great! We had a moisture problem in our kitchen cabinets that were on an interior wall. He spent a good amount of time figuring out what was going on, gave us a solution and answered all of our questions. A very good experience!
Good service.
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!
My unit for upstairs had a major leak in the evaporation coils. Jonathan and Matthew came over and spent an hour here investigating and giving me my options. I decided to replace the whole unit and they were here on a Saturday replacing the unit. The knowledge that Jonathan possessed was second to none. The experience was excellent I will be using them again and I highly recommend them.
Update: May 2026 Paradise came and serviced my business and home this week per the service agreement I asked them to sign me up for. Excellent trustworthy people and processes yields a top level result. You can trust them too. Call them and see what I mean. 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.
Jonathan and his staff were very communicative! Would highly recommend.
Always knowledgeable, respectful, and right on time!
Jonathan has serviced our AC unit for many years and I continue to trust his expertise. I would recommend him to anyone seeking an honest and fair HVAC company.
Great service, price, and quality workmanship! Highly recommend! I will use them again.
If you are having any HVAC issues please do not hesitate to call Paradise Heating and Air. Mr. Jonathan and his team were quick and provided answers to all my questions. I appreciate how quick they came out and fixed my issue being that we have had some extremely hot temperatures lately. I look forward to working with them in the future. I will be recommending them to anyone who has an issue. Thanks again to Paradise Heating and Air.
Jonathan provided another on-time, courteous and professional annual maintenance service call. Paradise Heating and Air provides great service at a great value.
Honest and kind. Gave incredible price for work completed. Called and was able to come earlier than expected! Cannot recommend enough
Has spring service. Right on time, got it in good shape. Professional. Highly recommend!
He was on time and got the insulation job done quickly. I had contracted with another company who no-showed twice, so being able to call Paradise and get it done within a short time was great.
Excellent service, very kind, and very reasonably priced. Went the extra mile to help me out. Really appreciate you guys!
Jonathan and the Paradise team are the best. In my 50 yrs of home ownership, I haven't had anyone I've trusted more. My wife and I downsized recently, and Jonathan helped us upgrade old to new heating & air units, including thermostats and attic insulation. Paradise Heating & Air is a great company... glad we found them years ago.
Extremely nice, on time, helpful and explanatory. Very professional. Thank you
My unit was not working and they were working with my relatives. I asked if they would take a look at mine and they did with no problem. They told me what the problem was an within 2 days they had my unit up and running!
Tech was on time, very professional, courteous, knowledgeable addressed my concerns about the system. Will definitely be recommending Paradise Heating and Air.
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.
Called Paradise on a Sunday(Father's Day) and got a call back and service/ repair the same day. They explained what was needed and did the necessary repairs. I have a nice cool home again.
Professional, on time, fair prices, great job!
Love their service. They are very prompt and courteous. They get any issues resolved immediately and are amazing to work with!
They were a 10/10 I do recommend
Paradise was very responsive and was able to come same day. Very professional, nice and honest - would recommend to anyone!
Being a first time customer I was extremely impressed with how punctual and professional the technicians are. I highly recommend Paradise Heating and Air
Jonathan is highly technical, knowledgable, and efficient. I wish I had known his company years ago. I highly recommend Paradise for all heating and air needs.
Routine service plus setting changes plus education plus rec's for the future. Spent much more time than normal to satisfy my real needs.
Explained options in detail in a way that I easily understood. No pressure to do unnecessary work. Very nice and professional team.
One of our AC units decided to give up, or so we thought. We had several companies come out and give us a quote to replace our unit, all exceeding $13k. Paradise came out, and instead of just giving a price to replace it, they asked if they could tinker with the equipment. They had it fixed within 10 minutes!!! Paradise gave us a quote so we have an idea of the cost for when this ancient unit ACTUALLY dies, and it was $3k-$8k cheaper than our other quotes!!! They could have easily just given us a price for a new unit like everyone else. I appreciate that Paradise put forth the effort to figure out the problem, and saved us THOUSANDS!!!
Always on time, easy to communicate, finest quality of workmanship and character, affordable pricing. Highly recommended.
Jonathan was nothing more than stellar. Very engaging as well as very knowledgeable at his profession. I would highly recommend to anyone looking for HVAC services.
They scheduled me in a timely manner. The technician (Jonathan)was very professional, explained the system, and answered all my questions.
I was extremely impressed with Paradise Air and am very glad I found them. I have a very old HVAC system they needed some ducts and a condensate pump replaced. They were extremely thorough and clearly explained everything they planned on doing. The price was excellent given how much work they had to do in the crawlspace and the extra time they spent with me advising me on how to get as much out of my old system as I could. They weren’t there to try to sell me a new system. They were there to repair what I asked them to at a reasonable price and help me extend the life of my current system. I won’t even think of calling anyone else from now on.
Johnathan and his son were excellent in installing a new hvac system in our home we had to have redone. They also fixed our upstairs unit and blew new insulation in our attic. They kept our home cleaned up as well. Great communication, very prompt and super friendly. We are so happy we found them!
I recently had this company come out to my home because my unit wasn’t working, they had someone out the same day. Jonathan was extremely professional and knowledgeable, definitely recommend this company!!
We had Jonathan out to service our unit today. The service was quick and efficient! Jonathan’s experience speaks for itself! We highly recommend Paradise Heating and Air for all your HVAC needs. Trevor and Edna Cumbee-Montieth Hoover, AL
