Ductless mini-split installation, repair, and maintenance for additions, finished basements, sunrooms, and older homes without ductwork, with room-by-room temperature control.
Ductless Mini-Split Services
Zoned Comfort Where Ductwork Falls Short
Ductless mini-split services provide efficient heating and cooling for spaces where traditional ductwork is impractical, too expensive, or simply not available. Many older Montgomery County homes heated by boilers have no ductwork for central air, and additions, finished basements, sunrooms, garages, and bonus rooms over garages often stay uncomfortable because existing systems cannot reach them effectively. A mini-split uses an outdoor heat pump connected by a small refrigerant line to one or more wall, ceiling, or floor units inside, each with its own thermostat. That zoning lets you heat or cool only the rooms you use, and because there are no ducts, there are no duct leakage losses. RLA Plumbing, Heating, and Air Conditioning installs, repairs, and maintains ductless mini-split systems 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 sizes each zone carefully, plans indoor unit placement for comfort, and provides fair, competitive pricing. Mini-split installation involves refrigerant line work, and Randy Aiken JR. is EPA Clean Air Act Section 608 Certified, Universal Classification, so every line set is charged and handled correctly.

Comfort Room by Room
Ductless Mini-Splits Installed for Efficient Comfort
Mini-splits deliver excellent comfort when sized and placed correctly. These practices guide every ductless project we complete across Montgomery County.
Ideal for Homes Without Ducts
Homes heated by boilers or baseboard systems often lack ductwork for central air. Mini-splits add efficient cooling and supplemental heating without tearing open walls and ceilings to install ducts throughout the house. Mini-splits operate very quietly.
Each Zone Sized Correctly
Oversized indoor units short cycle and leave rooms clammy, while undersized units struggle. We size each zone based on room size, windows, insulation, and sun exposure, so every space stays comfortable efficiently. Professional cleaning prevents odors.
Indoor Units Placed Thoughtfully
Placement affects airflow, comfort, and appearance. We position wall, ceiling, or floor units to distribute air evenly, avoid drafts on seating areas, and keep condensate lines and refrigerant piping as discreet as possible. Condensate lines need proper slope.
No Duct Losses
Traditional duct systems can lose significant heating and cooling energy through leaks and unconditioned spaces. Mini-splits deliver conditioned air directly into each room, avoiding those losses and improving overall efficiency. Inverter compressors adjust output smoothly.
Heating and Cooling in One System
Mini-splits are heat pumps, providing both summer cooling and winter heating. Cold-climate models continue heating efficiently in freezing weather, making them useful for additions and rooms that existing systems struggle to warm. Outdoor units need clear airflow.
Filters Kept Clean
Indoor mini-split units have washable filters that should be cleaned regularly, often monthly during heavy use. Dirty filters and coils reduce efficiency and airflow, so we show you how to maintain them properly. Some models offer smartphone control.

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!

How it works
How Ductless Mini-Split Service Works
Your ductless mini-split services begin with an evaluation of the rooms you want to heat or cool, including size, windows, insulation, sun exposure, and how each space is used. We discuss single-zone or multi-zone options, indoor unit styles and placement, outdoor unit location, and electrical requirements. You receive honest recommendations and fair, competitive pricing before installation or repairs are scheduled at a convenient time. Every zone is tested in both heating and cooling modes.
During installation, RLA Plumbing, Heating, and Air Conditioning mounts indoor and outdoor units, runs refrigerant and condensate lines neatly, connects electrical service, and tests every zone in heating and cooling modes. We explain remote controls and filter cleaning before leaving. To improve comfort further, our indoor air quality services add filtration and humidity control for homes throughout Blue Bell, PA and Montgomery County. Every zone is tested in both heating and cooling modes.
Common questions
Frequently asked questions
Can a mini-split heat my home in winter?
Yes. Mini-splits are heat pumps, and cold-climate models heat efficiently well below freezing. Many homeowners use them as primary heat in additions or as supplemental heat alongside boilers and furnaces. Rebates may help offset costs.
Are mini-splits a good option for homes with radiators?
Often, yes. Homes heated by boilers usually lack ductwork for central air. Mini-splits add efficient cooling without installing ducts, while radiators continue providing comfortable heat during winter. Line sets connect indoor and outdoor units. Clear pricing covers every zone.
How many indoor units will my home need?
It depends on room layout, size, and how you use each space. Open areas may need one unit, while separate bedrooms often need their own. A careful evaluation determines the right number. Wall units should avoid direct sunlight.
When should mini-split filters be cleaned?
Indoor filters are usually washable and should be cleaned about monthly during heavy use. Dirty filters reduce airflow and efficiency, and coils should be professionally cleaned periodically to prevent odors and buildup. Remote controls manage each zone independently.
Why is water dripping from my indoor mini-split unit?
Dripping usually comes from a clogged or improperly sloped condensate line, a dirty coil, or a frozen coil. Prompt service prevents water damage to walls, floors, and furnishings below the unit. Proper slope keeps condensate draining away from interior walls.
