Ductless Mini Splits


Hatfield Brothers Mechanical is a leading regional installer of Ductless Mini Split Air Conditioners to Keep You Comfortable All Year Long…

Our Ductless split installations are done by our own factory trained technicians who have extensive experience in their trades and in our products.  Our clients can have full trust and confidence in their ability.  They specialize in providing quick, dependable and quality service and are knowledgeable and courteous.

Sometimes there are areas in your home you would like to cool but their design has neither duct-work nor registers present. In areas like this we suggest using a mini-split system that places a self contained air handler in the room to provide the cooling. Also, mini-splits are available as heat pumps, which can provide both heating and cooling. Many systems today allow up to four air handlers to be attached to one condenser, allowing us to provide numerous options for cooling an area or series of rooms. Mini-split systems are energy efficient and excellent for sun rooms or homes with hydronic heating.

What is a Mini-Split?

Mini-splits are heating and cooling systems that allow you to control the temperatures in specific rooms. Mini-split systems have two main components -- an outdoor compressor/condenser and an indoor air-handling unit (evaporator). They are easy to install usually requiring only a three-inch hole through a wall for the conduit; which houses the power and communication cables, copper tubing, and a condensation drain line, linking the outdoor and indoor units.

Hatfield Brothers are experts on Mini-split systems, and are a great solution for houses with “non-ducted” heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They are also more energy efficient that other air conditioning systems.

We are proud to be able to provide the highest quality Ductless Mini-Split systems at the most competitive rates in the industry!
