A ductless mini-split system consists of one or more compact indoor air handlers paired with an outdoor compressor. Refrigerant lines and a condensate drain connect the two through a small wall opening—no bulky ductwork required. Key components include:
Indoor unit with inverter-driven fan and coil
Outdoor condenser/compressor with high-efficiency variable-speed technology
Wall-mounted remote controls or smartphone integration
Multi-zone capability for independent temperature settings in each room
Benefits for Brookline Homes
No Ductwork Disruption: Historic Brookline rowhomes often lack space for traditional duct runs. A mini-split system installs with minimal wall or ceiling intrusion—ideal for plaster walls or low clearances.
Zoned Comfort Control: Bedrooms over storefronts, finished basements and attic studios each have their own air handler, so occupants can customize cooling and heating to suit individual preferences.
Quiet Operation: Indoor units operate as low as 19 dB—comparable to rustling leaves—which makes them perfect for nurseries along Pioneer Avenue or work-from-home rooms on Brookline Boulevard.
Energy Efficiency: Seasonal Energy Efficiency Ratios (SEER) up to 30 and Heating Seasonal Performance Factors (HSPF) above 12 translate to significant energy savings, especially important during Pittsburgh’s humid summers and cold winters.
Flexible Installations: Single-zone units can cool a spare bedroom or attic suite, while multi-zone setups can serve entire first floors, small retail spaces on Brookline Boulevard, or home additions.
Our Ductless Mini-Split Services
Consultation & Custom Sizing
Every Brookline structure has its own quirks—ceiling heights, window orientations, insulation levels and occupancy patterns. The experts at Sureway Heating Cooling Plumbing perform a detailed Manual J load calculation to determine correct unit capacity (generally 20–25 BTU per square foot). We review zone layouts, electrical requirements and aesthetic considerations to propose a configuration that balances performance and budget.
Professional Installation Process
Site Preparation: We evaluate wall locations, electrical panels and condensate routing.
Refrigerant Line and Wiring: A small 3-inch hole connects indoor and outdoor units without cutting ducts or rafters.
Indoor Unit Mounting: Concealed metal brackets anchor each air handler, maintaining a low profile on interior walls.
Outdoor Condenser Placement: On-grade pad or wall-bracket mounting ensures optimal airflow and noise reduction.
System Commissioning: Refrigerant charging, leak testing, airflow balancing and full operational demonstration complete the install.
Repair & Seasonal Maintenance
Routine maintenance keeps ductless systems running at peak efficiency. Our checklist includes filter cleaning, condensate drain flushing, refrigerant-level inspection and firmware updates on smart-enabled units. For unexpected issues—frozen coils, communication errors or loss of cooling—Sureway Heating Cooling Plumbing offers same-day diagnostics and repairs using OEM parts.

Brookline Case Studies
Brookline Historic Rowhouse
A 1,200-sq-ft late-19th-century home on Groveton Street lacked ducts and had uneven heat distribution. Sureway Heating Cooling Plumbing installed a two-zone Mitsubishi system—an 18,000-BTU unit in the living room and a 9,000-BTU unit in the second-floor master bedroom. Result: summer cooling costs dropped by 25%, and winter heating was extended by two degrees without additional fuel.
South Winebiddle Street Condo Addition
Converting an attic to a home office required discreet comfort control. A single-zone Daikin unit with wall-hung indoor head delivered 12,000 BTU cooling and 12,000 BTU heating. Noise levels remained below 22 dB, preserving quiet work conditions. Installation was completed in one day by the Sureway Heating Cooling Plumbingteam.
