We offer same-day service for most emergency calls in Mandeville and surrounding areas. When your AC goes out during a Louisiana heat wave, we understand it’s not something that can wait until next week. We prioritize emergency calls and typically have a technician to your location within a few hours of your call. For non-emergency repairs and maintenance, we can usually schedule service within 24-48 hours. The key is calling us as soon as you notice a problem rather than waiting for a complete system failure.
Our maintenance service includes a complete system inspection, cleaning of key components, filter replacement, refrigerant level check, electrical connection inspection, and testing of all safety controls. We also check your thermostat calibration, inspect ductwork for leaks, and clean the condensate drain. After the service, you get a detailed report of what we found and recommendations for any issues that need attention. Regular maintenance typically extends equipment life by several years and helps prevent the majority of emergency breakdowns we see in the Mandeville area.
Yes, you get a clear price quote before we start any repair or installation work. Our technician will diagnose the problem, explain what needs to be done, and give you the total cost upfront. No surprise charges, no hidden fees, and no inflated prices after the work is completed. For larger jobs like system replacements, we provide detailed written estimates that break down equipment costs, labor, and any additional materials needed. You’ll know exactly what you’re paying and can make an informed decision about moving forward with the work.
Several factors help determine whether repair or replacement makes more sense for your situation. If your system is over 10-12 years old and needs frequent repairs, replacement often becomes more cost-effective. High energy bills, uneven cooling, strange noises, and poor air quality are also signs your system may be failing. We’ll assess your current equipment, explain your options, and help you understand the long-term costs of repair versus replacement. Sometimes a simple repair gets you several more years of reliable service. Other times, investing in a new system saves money and headaches in the long run.
The right system size depends on your home’s square footage, insulation levels, window types, ceiling height, and Louisiana’s climate factors. An oversized system will cycle on and off frequently, wasting energy and failing to remove humidity properly. An undersized system will run constantly and struggle to keep your home comfortable during peak summer heat. We perform detailed load calculations that account for your specific home’s characteristics rather than just using square footage rules of thumb. Proper sizing is critical for efficiency, comfort, and equipment longevity in our humid climate.
Yes, we provide comprehensive commercial HVAC services for businesses throughout Mandeville and St. Tammany Parish. This includes restaurants, retail stores, offices, medical facilities, and other commercial properties.

We understand that HVAC problems can shut down your business, so we prioritize commercial emergency calls and work around your business hours when possible. We also provide preventive maintenance contracts to help avoid costly breakdowns during peak business periods.
