Why Mandeville Homeowners Call Nu-Air Heating & Cooling, LLC First
We service all makes and models of HVAC equipment, so whatever system you have, we can work on it. Our emergency availability isn’t a third-party answering service routing calls to whoever’s on a dispatch board that night. It’s us: your local team, available any hour because we know what a South Louisiana summer without AC actually means.
Edgar is active in the St. Tammany Parish community and has built this business on repeat customers and neighbor referrals, not on volume from a national network. A locally based technician familiar with Northshore housing and climate conditions can move through diagnostics faster than someone dispatched from outside the area. NATE certification means our technicians are tested against a national standard for HVAC knowledge and repair quality. That matters most when the situation is urgent and the margin for a misdiagnosis is narrow. Customer satisfaction is guaranteed on every service call.
What Happens When You Call for Emergency Service
We answer the phone. From there, we get a technician to your property as quickly as possible, equipped to diagnose a wide range of HVAC failure types on the visit. Our goal is to identify the failure and address it during the same visit whenever possible, though outcomes depend on the specific situation and parts involved.
We start with on-site diagnostics to pinpoint the failure before attempting any repair. Common emergencies include total loss of cooling, refrigerant leaks, compressor failure, electrical faults causing repeated breaker trips, and water pooling near the indoor air handler. If replacement is the better path, we provide free estimates for replacement equipment so you can make an informed decision without pressure.
In Mandeville’s heat and humidity, a same-day or same-night response can be a genuine health matter for households with elderly residents, young children, or anyone with a medical condition affected by heat. We take that seriously.

“He really took his time explaining all of its features and what to expect from him and his service team.”Elizabeth G.

“Great communication and swift service! And a cool house!”Tova H.

“Edgar, the owner, came out originally to diagnose one of my A/C units not working. He quickly diagnosed the problem as a damaged circuit board, which he was able to retrieve from his supplier and replace within a couple of hours. However, while examining the unit, he found that the evaporator coil was leaking. He recommended replacing it, and said he could come out in a couple of days to do that job. In the quote he provided, he included a free charge of freon to the system to get through the next couple of days as long as we used him to replace the coil. In the meantime, I checked pricing from another HVAC company, and it was slightly less than Edgar's quote. Edgar showed up with an assistant on Thursday morning as promised and had the new coil in within about 3 hours. I was very pleased with the work and professionalism.”John W.

“Fantastic service, amazing attention to detail, very honest!”Wayne A.

“I would highly recommend Nu-Air! Called them on a Sunday morning when our A/C stopped working and thankfully Edgar came to check out it out. He had the part to us the next morning by 10am. He and Diego worked quickly to get our AC back up and running. They were very polite, respectful and professional! I have learned my lesson, forget the expensive home warranty (that came with the sale of the house) that in the end does not pay for itself. Instead, set up yearly maintenance with Nu-Air at 1/2 the cost of the warranty and catch any issues ahead of time. Thank you Edgar and Diego!!”Kelly H.
