Ductless Mini-Split AC in Mt. Lebanon, PA

What Is a Ductless Mini-Split System?

A ductless mini-split consists of two main components: an outdoor condenser/compressor and one or more indoor air-handling units. Each indoor unit mounts high on a wall or ceiling, connected to the outdoor unit by a small conduit that houses refrigerant lines, a condensate drain, and electrical wiring. Because there’s no ductwork to install or modify, mini-splits adapt easily to additions, finished basements, sunrooms, and older homes in Mt. Lebanon.

How Ductless Mini-Splits Work

At their core, mini-splits use inverter-driven heat pump technology to transfer heat in or out of a space. In cooling mode, indoor units absorb warm air and transfer it outdoors; in heating mode, the process reverses. Variable-speed compressors modulate output to match the precise cooling or heating load, avoiding the on/off cycling of traditional systems and delivering steady indoor temperatures. Sureway Heating Cooling Plumbing ensures every installation is customized for optimal efficiency.

Is a Mini-Split Right for Your Home?

Ideal applications include:

• Finished basements prone to humidity and musty odors
• Sunrooms, home offices, and room additions without existing ducts
• Older Mt. Lebanon homes where ductwork installation would disrupt historic trim and plaster walls
• Zoned cooling and heating for families with varying temperature preferences

A professional load calculation ensures each indoor unit’s capacity matches room size, insulation levels, and local heating requirements. Sureway Heating Cooling Plumbing performs detailed assessments for precise sizing, from 9,000 BTU for small dens to 36,000 BTU for open-concept living areas.

Step-By-Step Installation Process

Sureway Heating Cooling Plumbing follows a streamlined, code-compliant process to ensure clean, reliable installations:

• Site Survey & Load Calculation: A certified technician evaluates each room’s square footage, window area, and insulation quality. Local building codes, including Mt. Lebanon permit requirements, are confirmed during this visit.
• System Design & Permit Submission: We draft a system layout and submit permit applications to Mt. Lebanon’s Municipal Building. Most residential permits issue within 5–7 business days.
• Indoor/Outdoor Unit Placement: Indoor units are mounted on vibration-damping brackets; outdoor condensers install on ground pads or wall brackets. Linesets and wiring run through discreet 3-inch wall penetrations.
• Refrigerant Charging & Startup: After leak testing and vacuum dehydration, the system is charged to precise specifications. Commissioning includes airflow measurements and system diagnostics.
• Customer Orientation: We review controls, maintenance tasks, and recommended operating modes. Each homeowner receives a detailed operations guide.
