AC Installation in Orlando, FL
R.J. Kielty Plumbing, Air, Electric Inc. has been installing, replacing, and servicing AC systems across Greater Orlando since 1973. We’re a family-owned company with licensed technicians who understand exactly what it takes to keep Orlando homes and businesses cool, efficient, and comfortable year-round.
AC installation in Orlando is one of the most important investments you’ll make as a homeowner or business owner in Central Florida. With average summer temperatures regularly climbing above 90°F and humidity that makes it feel even hotter, a properly sized and professionally installed cooling system isn’t a luxury; it’s essential.



AC Installation Services We Offer in Orlando
Central Air Conditioning Installation
Central AC remains the most common cooling solution for Orlando homes. A central system uses ductwork to distribute conditioned air evenly through every room. R.J. Kielty installs high-efficiency central air conditioners with SEER2 ratings that meet or exceed current Department of Energy standards.
We assess your home’s layout, insulation levels, and existing ductwork before recommending a unit. If your ducts are leaking or undersized, we address that during installation. A properly sealed and insulated duct system can improve efficiency by 20% or more, according to the U.S. Department of Energy.

Ductless Mini-Split AC Installation
Ductless mini-splits are a smart option for homes without existing ductwork, room additions, garages, or sunrooms. Each indoor unit cools a specific zone, giving you independent temperature control in different areas of your home.
R.J. Kielty installs single-zone and multi-zone mini-split systems from leading manufacturers. These units are quiet, energy-efficient, and ideal for older Orlando homes where running new ductwork would be impractical or too expensive.
Heat Pump System Installation
Heat pumps provide both cooling and heating from a single unit. In Orlando’s mild winters, a heat pump handles the occasional cold snap without the need for a separate furnace. This makes heat pumps one of the most cost-effective year-round comfort solutions for Central Florida homeowners.
R.J. Kielty installs both air-source and ductless heat pump systems. We help you select the right capacity and efficiency rating based on your home’s size and your energy goals.
Commercial AC Installation in Orlando
Commercial properties have different cooling demands than residential homes. Office buildings, retail spaces, restaurants, and warehouses each require systems designed for their specific load, occupancy patterns, and ventilation requirements.
R.J. Kielty designs and installs commercial HVAC systems, including rooftop units, split systems, and VRF (variable refrigerant flow) systems. We work with property managers, business owners, and general contractors to deliver installations on schedule and within budget.
AC Replacement and System Upgrades
If your current AC system is over 10–15 years old, runs constantly, or requires frequent repairs, replacement is likely more cost-effective than another fix. Newer systems use significantly less energy. Upgrading from a 10-SEER unit to a 16-SEER system can cut your cooling costs by nearly 40%.
R.J. Kielty evaluates your existing equipment and recommends replacement options that fit your home and budget. We remove and dispose of your old system and complete the full installation, usually within a single day.
