When Should You Replace Your Air Conditioner?
It’s one of the most common questions we hear: repair or replace? Age is a factor, but it’s rarely the only one.
Five signs that replacement may be the better call:
- System age – A system that’s 10 to 15 years old is approaching the end of its typical service life and may be a candidate for replacement
- Frequent repairs – Recurring breakdowns often signal that a system is no longer reliable
- Rising utility bills – Aging equipment loses efficiency and draws more energy to deliver the same cooling
- An expensive repair – If a repair approaches or exceeds half the cost of a new system on a unit over 10 years old, replacement is typically the better investment
- R-22 refrigerant – R-22 is no longer produced or imported into the United States, making it increasingly expensive to source; systems that depend on it can become costlier to maintain
Our NATE certified technicians can inspect your system, walk you through the repair-versus-replace decision, and provide a free estimate if a new system makes sense. No pressure: just straightforward guidance from technicians who know the equipment.
Choosing the Right AC System for Your Mandeville Home
Selecting the right system matters as much as installing it correctly. Our comfort team carries extensive product knowledge and is Trane Variable Speed certified, which means we can assess whether a variable-speed system is the right fit for your home.
Variable-Speed Systems & Humidity Control
Unlike single-stage units that run at full capacity until they switch off, variable-speed systems modulate their output to match demand. In Mandeville’s high-humidity climate, that can translate to longer, lower-speed cycles that can pull more moisture out of indoor air, not just lower temperatures.
Sizing, SEER Ratings, & Local Climate
Proper sizing requires accounting for square footage, ceiling height, insulation, window placement, and local climate conditions. An undersized system runs constantly without reaching your target temperature. An oversized system short-cycles and leaves excess humidity behind. SEER (Seasonal Energy Efficiency Ratio) ratings are another key factor: the higher the rating, the less electricity the system needs to do its job. Our comfort team draws on more than 20 years of HVAC industry experience to guide that process for homeowners in Mandeville, Covington, and throughout St. Tammany Parish.

He was extremely professional and honest, even reviewing a previous invoice from another company for work that we had done to ensure we hadn’t already for what for he completed. I will absolutely call him again and will recommend him to friends and family.”Chrissy

“Edgar does Fantastic work! My employer had us get three price quotes on the work to be done at our store. NU Air gave us a more than fair offer to perform the work. Edgar went above and beyond my expectations in his service. In fact he was out in the rain installing our roof mounted Central Air! Thank You! I would highly recommend NU Air for commercial and residential.”Lee A.

“Edgar was quick to respond and provided us with options on a new system which were more competituve than the quotes we received. In 36 hours we were financed and cool with a system with the system we wanted for AC and heat.”Samantha

“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.
