AC Replacement in New Port Richey, FL
AC replacement is one of the most significant home comfort investments you’ll make in Florida. In a climate where your air conditioner runs eight to ten months per year, choosing the right system, and the right installer, directly affects your energy bills, indoor comfort, and long-term reliability.
R.J. Kielty Plumbing, Air, & Electric Inc. has helped homeowners and business owners across the New Port Richey area make smart AC replacement decisions since 1973. Our process goes well beyond swapping out old equipment. We size your new system precisely, install it to manufacturer specifications, and verify performance before we leave your property.




Our Comprehensive AC Replacement Services in New Port Richey
A proper AC replacement involves far more than disconnecting one unit and connecting another. Each step in our process is designed to ensure your new system performs at its best from day one and continues to deliver reliable cooling for years.
Precision Load Calculations for Proper System Sizing
An oversized AC unit short cycles, creates uneven temperatures, and wears out faster. An undersized unit runs constantly and never fully cools your home. Both waste energy and money.
R.J. Kielty’s technicians perform Manual J load calculations before recommending any equipment. This industry-standard method accounts for your home’s square footage, insulation levels, window orientation, duct layout, ceiling height, and local climate data specific to the Gulf Coast. The result is a system sized exactly for your property, not a guess based on what was there before.
Safe Removal and Disposal of Your Old AC Unit
Old air conditioning systems contain refrigerants, oils, and components that require careful handling. Our technicians recover all refrigerants according to EPA Section 608 regulations before disconnecting your existing equipment.
We remove the old condenser, evaporator coil, and any related components, then transport them for proper recycling or disposal. You don’t need to worry about leftover equipment sitting in your yard or hazardous materials being mishandled.
Professional Installation of High-Efficiency Air Conditioning Systems
The quality of an AC installation determines how well the system performs over its entire lifespan. Even the best equipment underperforms if it’s installed incorrectly. Studies from the Department of Energy confirm that improper installation can reduce system efficiency by up to 30%.
Our installers follow manufacturer guidelines and local building codes at every step. We secure all electrical connections, seal ductwork joints, mount components level and plumb, and verify proper airflow across the evaporator coil. We install systems from leading brands with SEER2 ratings that meet or exceed current federal efficiency standards.
Thorough Testing and Calibration for Peak Performance
Once your new AC system is physically installed, we test every function. Our technicians measure supply and return air temperatures, check refrigerant charge levels, verify thermostat operation, and confirm that the system cycles correctly.
Calibration matters because factory settings don’t always match real-world conditions. We adjust airflow, refrigerant levels, and control settings to match your home’s specific requirements. This step ensures you get the full efficiency and comfort the manufacturer intended.
Complete Safety Checks and Code Compliance Inspections
Every AC replacement we perform meets Florida Building Code requirements. Our team inspects electrical connections, verifies circuit breaker sizing, checks condensate drain lines, and confirms that the outdoor unit has proper clearances.
We also coordinate with local building inspectors when permits are required. This protects your investment and ensures your new system passes inspection without delays or callbacks.
Certified Refrigerant Management and Handling
Federal law requires EPA Section 608 certification for anyone handling AC refrigerants. All R.J. Kielty technicians hold current certifications. We recover, reclaim, and charge refrigerants using calibrated equipment and approved procedures.
If your old system uses R-22 (Freon), which was phased out of production in 2020, your replacement will use R-410A or the newer R-454B refrigerant. We’ll explain the differences and help you understand what each option means for long-term performance and service costs.
