Modern Cooling Technology for Baton Rouge Homes

AC replacement becomes necessary when repair costs exceed half the unit’s value or when systems exceed 12-15 years of operation. Older units lose efficiency ratings, causing energy bills to climb 20-35% above normal levels. Modern air conditioning systems use variable-speed compressors and smart thermostats that adapt to your home’s specific cooling demands.

Our installation process includes load calculations that determine exact tonnage requirements for your square footage. Oversized units cycle on and off frequently, wasting energy and failing to remove humidity effectively. Properly sized systems run longer cycles that maintain consistent temperatures while removing moisture that makes Louisiana heat feel oppressive.
