Mini Split Units

Ductless, mini split-system air-conditioners (mini splits) have numerous potential applications in residential, commercial, and institutional buildings. The most common applications are in multifamily housing or as retrofit add-ons to houses with "non-ducted" heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions and small apartments, where extending or installing distribution ductwork (for a central air-conditioner or heating systems) is not feasible.

Like central systems, mini splits have two main components: an outdoor compressor/condenser, and an indoor air-handling unit. A conduit, which houses the power cable, refrigerant tubing, suction tubing, and a condensate drain, links the outdoor and indoor units.

The main advantages of mini splits are their small size and flexibility for zoning or heating and cooling individual rooms. Many models can have as many as four indoor air handling units (for four zones or rooms) connected to one outdoor unit. The number depends on how much heating or cooling is required for the building or each zone (which in turn is affected by how well the building is insulated). Since each of the zones will have it's own thermostat, you only need to condition that place when someone is there. This will save energy and money.

Goyette Mechanical has been on the front line of sales and installation of these innovative air conditioning systems. Goyette offers multiple brands and sizes for any and all applications.


We install closed loop geothermal systems professionally designed and engineered to optimize efficiency and comfort.

There are four major types of closed loop systems. Horizontal loops, vertical loops, slinky loops, and pond loops.

In horizontal geothermal ground loops, several hundred feet of five to six feet deep trenches are dug with a backhoe or chain trencher. Piping is then laid in the trench and backfilled. A typical horizontal ground loop will be 400 to 600 feet long for each ton of heating and cooling. Because of the amount of trenching involved, horizontal ground loops are most commonly used for new construction.

In vertical geothermal ground loops, a drilling rig is used to drill 150 to 300 foot deep holes in which hairpin shaped loops of pipe are dropped and then grouted. A typical vertical ground loop requires 300 to 600 feet of piping per ton of heating and cooling. Vertical loops are typically more expensive than horizontal loops, but are considerably less complicated than drilling for water. Less piping is also required for vertical geothermal ground loops as opposed to horizontal loops as the earth's temperature is more stable at depth.

Slinky coil geothermal ground loops are gaining popularity, particularly in residential geothermal system installations. Slinky coil ground loops are essentially a more economic and space efficient version of a horizontal ground loop. Slinky coils, as you might expect, use overlapped loops of piping laid out horizontally along the bottom of a wide trench. Depending on soil, climate and your heat pumps' run fraction, slinky coil trenches can be anywhere from one third to two thirds shorter than traditional horizontal loop trenches.

Geothermal Pond Loops If at least a ? acre by 8 ft deep pond or lake is available on your property, a closed loop geothermal system can be installed by laying coils of pipe in the bottom of a body of water. However, a horizontal trench will still be needed to bring the loop up to the home and close the loop. Due to the inherent advantages of water to water heat transfer, this type of geothermal system is both highly economical and efficient.
