AC Installation in New Port Richey, FL

Central AC remains the most popular cooling solution for homes and businesses in the New Port Richey area. R.J. Kielty installs complete central air conditioning systems, including the outdoor condenser, indoor air handler, thermostat, and all necessary ductwork connections.

Our technicians perform a Manual J load calculation before recommending a system size. This ensures your new unit matches your home's square footage, insulation levels, window placement, and local climate conditions. An oversized unit short-cycles and wastes energy. An undersized unit runs constantly and never reaches your desired temperature. Getting the size right matters more than most homeowners realize.

Ductless mini-splits are an excellent option for homes without existing ductwork, room additions, converted garages, or older properties along neighborhoods like Beacon Square and Gulf Harbors where retrofitting ducts isn't practical.

Each mini-split system includes an outdoor compressor and one or more indoor air-handling units mounted on walls or ceilings. They provide zone-based cooling, which means you only condition the rooms you're using. R.J. Kielty installs single-zone and multi-zone configurations from top manufacturers, and we size each system based on the specific space it serves.

Older AC systems rated at 10 SEER or below cost significantly more to operate than modern high-efficiency units. Upgrading to a 16 SEER or higher system can reduce your cooling costs by 30–50%, depending on your current equipment and usage patterns.

R.J. Kielty installs variable-speed and two-stage AC systems that adjust output based on real-time demand. These units maintain more consistent indoor temperatures, reduce humidity more effectively, and run quieter than single-stage systems. We also install smart thermostats that pair with your new high-efficiency unit for even greater energy saving.

Businesses along US-19, the Little Road corridor, and throughout the New Port Richey commercial district rely on R.J. Kielty for commercial AC installation. We install rooftop units, split systems, and packaged HVAC systems for offices, retail spaces, restaurants, and warehouses.

Commercial AC installation requires different load calculations, zoning strategies, and equipment than residential work. Our team has over 50 years of experience sizing and installing systems that handle the unique demands of commercial spaces, from high-occupancy restaurants to temperature-sensitive server rooms.
