Ductless Mini Split Installations​

Mini split air conditioners work similarly to other types of air conditioners in that they compress and expand refrigerant to pull away heat and moisture from the air. There are some significant differences between mini split air conditioners and other types of air conditioners, and they include:

Heat Pumps​

 How are ductless air conditioners, or mini split air conditioners, capable of heating and cooling without needing large indoor and outdoor units? The secret lies in energy-efficient heat pumps. They take advantage of heat’s tendency to move from warm areas to cool areas. In doing so, they are capable of heating and cooling while using a lot less energy.


As with a traditional heating and cooling system, mini split systems have indoor and outdoor components. In this case, however, the indoor and outdoor units are connected by suction lines, which draw away condensate, refrigerant lines, which facilitate the transfer of warm air, and power lines, which keep everything working correctly.

Indoor Units​

With a mini split air conditioner, outdoor units are mounted on outside walls. There are also compact indoor units, which may be mounted on floors, ceilings or high up on walls. These units have blowers that deliver heated and cooled air to a specific area.

Commonly Asked Residential HVAC Questions

Your home is cooled and heated by a residential HVAC system, which can feature solutions like air conditioning systems, furnaces, thermostats, heat pumps and ducts, along with the corresponding controls intended to enhance the comfort in your home. HVAC simply stands for heating, ventilation, and air conditioning systems. Without a residential HVAC system working properly in your home, you wouldn’t have the heat you need in the winter or the cool air we all crave during a summer heatwave.

There is no single answer for how much a new residential HVAC system costs. The total price comes down to your requested features, the size of the space, and what type of solutions we recommend in order to optimize the comfort of your home for you and your family.

As the HVAC industry has evolved and improved, we now have different types of residential HVAC systems available to homeowners. Generally speaking, a residential HVAC system is built from the following requisite parts: condensing unit, evaporator coil, furnace, refrigerant lines, thermostat, and vents. Depending on the type of system, your home might be equipped with both interior and exterior HVAC components. Typically, homeowners will choose from the following four categories of residential HVAC systems:

  1. Duct-free split system
  2. Traditional HVAC split system
  3. Humidity control, which includes humidifiers and dehumidifiers
  4. Zoned systems

The best residential HVAC system for your project is going to vary based on your needs. For the most accurate information for your project, contact our team of experts today.

There is a pretty straightforward formula to help you determine how to size your residential HVAC system. Typically, it requires approximately 25 BTUs to effectively cool a single square foot of your home. Keep in mind that this simple formula is a great starting point, but doesn’t take into account details like high volume rooms (think living room, den, kitchens). For these spaces, it’s a good idea to reserve an additional 500 BTUs. If the air conditioning system you’re considering is measured in tons, rather than BTUs, just remember this quick conversion: t ton = 12,000 BTUs.
