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.

“Edgar and crew installed a new electric panel at my house, they also moved a/c return and a few other things. They are reliable, the work was done when promised and they cleaned up the work area and even swept my floor. Thanks for the great work.”Lorena
-
“My AC went out on a Thursday night in the middle of the summer and after calling several HVAC companies who couldn't get to me until the following Monday, I called Nu-Air. Nu-Air arrived within a couple of hours and diagnosed my problem. Edgar walked me through my options and had estimates to me the same evening. Edgar located equipment at the distributor, picked it up, and worked late into the night to give my wife and I relief from the summer heat. I had my new AC system installed and the house cool before the other companies could even make it out to assess the situation. Nu-Air truly stands out in a world where customer service has mostly been lost.”Kevin
-
“If there were more stars, I would give them. Edgar and his assistant worked from 9:00 in the morning until 5:00 in the New Orleans heat to get my OLD unit working like it was new. They did an excellent job and were so courteous. AND, not only cleaned up there mess, but made sure the floor was swept better than I could do. I would DEFINITELY recommend them to anyone.”Stanley D.
