Mini Split HVAC Systems
Precision Comfort Without the Ducts
Mini split systems help you take control of your comfort with an energy-efficient ductless heating and cooling solution.
Mini Splits Explained
Mini splits are known for their energy efficiency and ease of installation, particularly in homes without existing ductwork.
They allow you to control temperatures independently in different zones of your home.
In the diverse climate we see in southeastern Pennsylvania and northern Delaware, mini splits provide efficient cooling to combat the region’s high humidity, and heat and reliable heating even in freezing temperatures.
Mini Splits are best for:
- Older and historical homes where the architecture or historical preservation constraints make installing extensive ductwork impractical
- New additions, such as sunrooms
- Garages converted into living spaces
- Expanded kitchen areas

Mini Split vs Ducted HVAC Systems
Mini Split System
Mini splits are modern, ductless heating and cooling systems that can last between 15 and 20 years with proper care.
They have an outdoor compressor unit connected to one or more indoor air handling units. To connect it to the outdoor unit, a small conduit runs through a three-inch hole in the wall.
Mini splits can be installed on an exterior or interior wall, as long as the line can be run from the compressor to the indoor unit through a wall, basement, etc, you’re good to go.
These systems offer higher efficiency, easier installation, and flexible zoning but may not blend seamlessly with all interior designs.
Mini split systems are ideal for homes without existing ductwork, additions, or areas needing independent temperature control.
Choose a mini split if…
- Extending the ducts is difficult because your addition is detached or far from the main house
- Cutting into walls is unfeasible because they’re load-bearing or protected historical structures
- You prefer zone-specific temperature control to enhance energy efficiency
- Installation speed and minimizing home disruption are priorities for you
A mini split is not ideal if…
- You have multiple large areas that requires uniform heating and cooling
- You prefer a completely integrated system with no visible indoor units
- You are looking for a system that can seamlessly blend with your existing interior design without any visible changes
- Your home already has an efficient and functional ducted system
Ducted HVAC
Traditional ducted HVAC systems use a central unit to heat or cool air, which is then distributed throughout the home via a network of ducts.
The main components include the furnace to heat the air, the AC unit to cool the air, the blower fan that circulates the air, and the network of ducts that deliver the air to various rooms.
These systems rely on a single thermostat to regulate the temperature, providing uniform climate control throughout the home.
If your home already has a duct system installed, you can potentially get an extension done for add-ons or rooms that need a little more airflow.
Choose a ducted HVAC duct extension if…
- The room you’re trying to heat/cool is large, and/or ductwork can be easily routed to it
- You prefer not to have visible indoor units
- Your existing HVAC system is sufficiently powerful to handle more rooms
- You value having a single, unified system to manage the climate control in your home
Ducted HVAC is not ideal if…
- Your home does not already have ductwork or the infrastructure to easily add it
- You have space constraints that make routing ductwork difficult or impossible
- You want a quick and easy installation process
- You prefer individual control over the temperature in different rooms or zones
- You are looking for a more energy-efficient solution for specific rooms
Mini Splits for Homeowners in Southeastern Pennsylvania and Northern Delaware
Living in southeastern Pennsylvania and northern Delaware means experiencing a wide range of weather conditions, from hot, humid summers to cold, snowy winters.
Mini split systems offer significant benefits for these varied climates…
- During the summer, mini splits provide efficient cooling to combat the region’s high humidity and heat.
- During the winter, they deliver reliable heating even in freezing temperatures.
With zone-specific temperature control, you can adjust the climate in individual rooms, enhancing comfort and energy efficiency.

How much does a Mini Split Cost?
The cost of a mini split system can vary widely based on several factors, including the number of indoor units and the complexity of the installation.
On average, the cost can range from $1,500 to $8,000 or more.
Single-Zone Systems
Typically cost between $1,500 and $3,000, including installation. These systems are ideal for small spaces or individual rooms.
Multi-Zone Systems
Range from $4,000 to $8,000 or more, depending on the number of indoor units and the complexity of the installation. These systems can provide climate control for multiple rooms or zones within a building.
Installation Costs
Vary based on the difficulty of the installation, including the distance between the indoor and outdoor units and any necessary electrical or structural modifications. Installation costs can range from $500 to $2,500 or more.
Operating Costs
Mini splits are generally more energy-efficient than traditional systems, which can result in 30% to 40% lower energy bills. However, regular maintenance is necessary to ensure optimal performance and longevity.

Maintenance Requirements for Mini Splits
Other than the monthly filter cleaning, mini split maintenance is nothing more than an annual servicing of the units.
If your mini split supplements your ducted HVAC system, just let the technician know, and they’ll be able to perform maintenance for both systems in the same visit!
Cleaning Filters
Mini splits have washable filters. They should be cleaned monthly to keep air flowing and indoor air clean.
Cleaning involves removing the filters from the indoor units and washing them gently with water.
Servicing the Outdoor Unit
The outdoor component of a mini split system also requires annual checks. It should be kept clear of debris, leaves, and dirt, which can obstruct the condenser coils and reduce the system’s efficiency.
A professional should check the refrigerant levels and inspect the electrical connections annually.
Checking the Indoor Unit
In addition to filter cleaning, the technician will check for signs of condensation or leakage.
They will also clean the coils to ensure dust doesn’t reduce efficiency.
The Kauffman Choice: Mitsubishi Mini Splits
Kauffman Gas explicitly installs Mitsubishi mini split systems for their excellent energy efficiency and reliability.
You can choose between single-zone and multizone, which can power up to 5 indoor units, although larger models can power up to 11.
Their ductless cooling and heating systems follow ENERGY STAR guidelines, which means they’re far more energy efficient than the U.S. government’s minimum standards.
The average wall-mounted air handler is 12x32x9 inches. The average outdoor unit for one to two handlers is 24x32x12 inches. After that, they get a little wider—up to two feet deep instead of one.
Mini Split Installation Process: What to Expect
Each Mitsubishi unit typically takes less than a day to install.
Even multi-zone systems can be set up in just a few days.
1. Site Assessment
A technician assesses the best spots for the indoor and outdoor units.
For the indoor unit, the technician measures the square footage of the space and takes a heating/cooling load calculation to make sure the unit is the right size for the space. After that, it’s just a matter of choosing where in the room to install the unit based on orientation and preference.
For the outdoor unit, considerations include avoiding direct sunlight and ensuring adequate space for the outdoor unit.
2. Installing the Units
Indoor units are typically mounted on walls or ceilings. They require only a small hole (about three inches in diameter) through the external wall for the conduit.
The outdoor unit is placed on a stable level surface made from a concrete pad or wall brackets.
3. Connecting Indoor and Outdoor Units
The conduit connects the indoor unit to the outdoor unit. It houses the power cable, refrigerant tubing, and a drain for condensation.
4. System Testing
Once installed, each unit is tested to ensure it operates efficiently and effectively cools or heats the designated zones.
