Single-Zone Mini Split AC Installation for Garages

Many Virginia homeowners use their garages as gyms, workshops, or additional living areas. However, during much of the year, garage temperatures can exceed 90°F, making these spaces unusable without climate control. While adding central AC isn't typically allowed without full conversion and permitting, ductless mini split systems provide a cost-effective and code-friendly solution.

In many municipalities, these systems can be installed for dehumidification or full climate control with only minor upgrades—such as attic insulation and an insulated garage door—making them an ideal garage cooling option.

Ductless Mini Split Systems for Supplemental Cooling

Homes with undersized ductwork or hard-to-reach areas often struggle with uneven temperatures. In multi-story homes, the upper floors can be significantly warmer due to rising heat and thermostat placement on the main level. When ductwork upgrades aren't feasible, ductless mini splits offer a reliable alternative.

We install single-zone or multi-zone ductless systems to provide targeted cooling for problem areas like upstairs bedrooms or additions. These systems improve airflow, deliver balanced temperatures, and offer independent control of each room or zone.

Ducted Mini Split Systems: Central AC Replacement

Is your central HVAC system outdated, inefficient, or failing? Ducted mini split systems can replace your traditional setup using compact, quiet, and high-efficiency air handlers. These systems fit into the same locations as conventional air handlers and pair with high-SEER outdoor units for powerful and efficient performance.

With brands like Trane and Mitsubishi, you get modern features, outstanding dehumidification, and flexible installation—especially beneficial in tight or hard-to-condition spaces.

Whole-Home, Multi-Zone Mini Split Systems

Want lower utility bills and personalized comfort? Whole-home ductless systems allow for zone-by-zone climate control, cutting energy waste and increasing comfort. Each room gets its own thermostat, and inverter-driven technology reduces energy usage by up to 40%, according to Mitsubishi.

These systems eliminate duct loss and allow you to condition only the rooms in use. Compared to traditional zoning systems, ductless options are more efficient, easier to install, and more reliable.

Hybrid Mini Split Systems

Hybrid systems combine ductless condensing units with conventional air handlers to create cost-effective, high-efficiency HVAC solutions. Carrier's Performance Crossover System is one of our top recommendations for Northern Virginia homes, offering variable-speed performance, excellent heating in low temps, and minimal reliance on electric heat strips.

Mini Split AC FAQs

What is a mini split air conditioner?

Mini split AC systems offer flexible installation and high energy efficiency. Most are ductless and consist of an outdoor condenser and one or more indoor air handlers. They include key components like compressors, coils, and blowers, but don’t require ductwork like traditional central systems.

How much does a mini split AC system cost?

Prices vary based on brand, size, and installation needs. For a high-quality single-zone Trane/Mitsubishi or Carrier system, expect to pay $4,500–$8,500 including installation, permits, and electrical upgrades. Larger or luxury models may cost over $10,000.

What is the best mini split AC brand?

Mitsubishi mini splits are widely regarded as the most reliable, offering excellent warranties and long-term value. Carrier is also a trusted brand with great performance and parts support.

What size mini split system do I need?

Accurate sizing depends on a professional load calculation. Factors like insulation, window size, and room type all affect the required capacity. Bedrooms often need 6,000–9,000 BTUs, sunrooms 12,000–18,000 BTUs, and garages up to 30,000 BTUs. Always consult a licensed contractor for proper sizing.
