If your system is over 10-12 years old and needs frequent repairs, replacement usually makes more financial sense. When repair costs start reaching 50% of a new system’s cost, or if your energy bills keep climbing despite repairs, it’s time to replace. Also, if your AC can’t keep up with Louisiana heat even after repairs, the system is likely undersized or worn out beyond effective repair.
Most residential AC replacements take 4-8 hours for a straightforward swap. If we need to modify ductwork, upgrade electrical, or handle other complications, it might take a full day. We’ll give you a realistic timeline upfront. We know you need your AC working, especially during summer, so we work efficiently without cutting corners on the installation quality.
Size depends on your home’s square footage, insulation, window placement, and Louisiana’s specific climate demands. Bigger isn’t always better – an oversized unit won’t remove humidity properly and will cycle on and off too frequently. We do proper load calculations to determine the right size. Most Madisonville homes need between 2-5 tons of cooling capacity, but we measure rather than guess.
Costs vary based on system size, efficiency rating, and installation complexity. Basic units start around $3,000-4,000 installed, while high-efficiency systems can run $6,000-8,000 or more. We provide upfront pricing after evaluating your specific situation. Financing options are available, and remember that a more efficient system often pays for the difference through lower energy bills over time.
If your indoor and outdoor units are mismatched in age or efficiency, replacing both usually works better. Mixing old and new components can reduce efficiency and void warranties. However, if your indoor unit is newer and compatible, sometimes you can replace just the outdoor unit. We’ll assess your specific situation and recommend the most cost-effective approach that actually works.
Fall through early spring offers the best timing – you’re not desperate, contractors aren’t slammed, and you have time to research options. However, we handle emergency replacements year-round because Louisiana heat doesn’t wait. If your system fails during summer, don’t suffer through it. We stock common units and can usually get you back up and running quickly even during peak season.
