Beat the Summer Heat With a Properly Sized New Air Conditioner
Central air conditioner installation and replacement, sized correctly for your home, with efficiency options explained clearly and installation done to manufacturer standards.
AC Installation & Replacement
New Cooling Systems Sized for Your Home
AC installation and replacement determines how comfortable, efficient, and dependable your home will be for the next 15 years or more. Replacing an air conditioner involves more than swapping equipment. Proper sizing depends on square footage, insulation, windows, sun exposure, and ductwork, not simply matching the size of the old unit. An oversized system cools quickly but short cycles, leaving homes clammy during humid Pennsylvania summers, while an undersized system runs constantly and struggles on the hottest days. Matching the outdoor condenser with the indoor coil and furnace or air handler also affects efficiency and warranty coverage. RLA Plumbing, Heating, and Air Conditioning installs and replaces central air conditioners for homes and businesses in Blue Bell, PA and surrounding Montgomery County communities. Owned and operated by Randy Aiken JR., a Registered Master Plumber with more than 30 years of industry experience, our team explains efficiency ratings and options honestly, provides fair, competitive pricing, and installs systems with careful attention to refrigerant charge, airflow, and drainage.

New Cooling, Installed Right
AC Installations That Deliver Lasting Comfort
A new air conditioner only performs as well as its installation. These practices guide every AC installation and replacement we complete across Montgomery County.
Sizing Based on Your Home
Proper sizing considers insulation, windows, sun exposure, and ductwork, not just square footage or the old unit's size. Correct sizing prevents short cycling and humidity problems common with oversized systems in Pennsylvania homes. Matched systems protect manufacturer warranties.
Matched System Components
Outdoor condensers, indoor coils, and furnaces or air handlers should be matched for rated efficiency and warranty coverage. Mismatched components can reduce performance and create problems that appear years after installation. Condensate pumps protect finished basements.
Efficiency Explained Clearly
SEER2 ratings measure cooling efficiency, and higher ratings lower operating costs. We explain how efficiency choices affect upfront cost and long-term savings, so you choose a system that fits your budget honestly. Old refrigerant is recovered responsibly.
Refrigerant Charge Verified
Incorrect refrigerant charge is one of the most common installation mistakes, reducing efficiency and shortening compressor life. We verify charge and airflow during startup, so your new system operates the way manufacturers intended. Proper sizing improves humidity control.
Drainage Protected From the Start
Air conditioners remove gallons of moisture daily during humid summers. We install proper condensate drains, traps, and pumps where needed, protecting basements, attics, and ceilings from water damage. Higher SEER2 ratings reduce summer electric bills.
Fair, Competitive Pricing
Our pricing is straightforward and competitive, with clear explanations of equipment, labor, and options. You receive honest recommendations rather than pressure toward expensive features your home does not need. Manual J calculations guide proper sizing.

We have depended on Randy's expertise for multiple home projects. He is our first call whenever a need arises with our plumbing or HVAC. In addition to knowing his stuff and never steering us wrong, he is also reliable and trustworthy. We couldn't recommend RLA more!
Beth Wood
Highly recommend Randy! My 2-year-old decided our toilet was the appropriate place to dispose of a baby spoon and, unsurprisingly, the toilet did not agree. When the plumber who initially worked on the system left without finishing the job, Randy came over and had everything working perfectly again in no time. He was knowledgeable, efficient, and clearly knew what he was doing. If you’re looking for a reliable plumber—or have a toddler who likes to test the limits of your plumbing—I would definitely recommend him!

Common questions
Frequently asked questions
How do I know what size air conditioner I need?
Proper sizing depends on insulation, windows, sun exposure, ductwork, and layout, not just square footage. A load calculation provides an accurate answer, while matching the old unit's size can repeat past mistakes. Electrical disconnects are installed to code.
Why does my home feel clammy even when the AC runs?
Oversized air conditioners cool rooms quickly and shut off before removing enough humidity. Dirty coils and airflow problems also reduce moisture removal. Correct sizing and maintenance help homes feel comfortable, not just cool. Duct leaks waste new system efficiency.
What does SEER2 mean?
SEER2 measures cooling efficiency under updated federal testing standards introduced in 2023. Higher ratings lower operating costs, though savings depend on how much you run your system during summer. Most replacements finish in one day.
Should I replace my furnace and air conditioner together?
Replacing both at once ensures matched components, consistent efficiency, and coordinated warranties. If your furnace is relatively new, replacing only the air conditioner with a properly matched coil can also work well. Clear pricing covers equipment and labor.
When will AC installation be finished?
Most residential replacements are completed in one day, depending on equipment type, ductwork changes, and electrical upgrades. New installations in homes without ductwork take longer, and we provide a timeline upfront. Outdoor units are leveled on proper pads.
