Whether you are retrofitting your office, or adding an addition where ducts are not feasible, ductless mini split heat pumps are a great idea. However, trying to install one on your own isn’t recommended. There are tools needed that a homeowner or commercial space maintenance personnel likely won’t have, and if the installation is off at all it can lead to loss of energy and the system not operating correctly.
Installing a Ductless Mini Split
The mini split system is a two part system, both an indoor air handling unit and an outdoor power unit condenser/compressor. A conduit power line is run between the two and contains the refrigerant and suction tubing along with a condensation drain.
To install, an HVAC professional will drill a 3-inch hole and running the copper line, mount the indoor unit and place the outdoor unit on its recommended concrete pad. Then they’ll set the gauges and couplings, vacuum the lines, insert the refrigerant and test for leaks. While some split systems may claim to be a “quick connection,” these vital steps still must be done by a professional in order to guarantee the unit and system is operating correctly.
Installing a ductless mini split will add flexibility to a home’s zoning, giving you the option to heat or cool just one room or area. This offers significant savings on your energy costs. The amount of money for the installation by a professional HVAC contractor will likely be recouped in the first few months of operation. Further, if there is any leak in your line later, the HVAC contractor can then fix it easily.
Having a professional HVAC or commercial air conditioning installation is the best bet for top efficiency of a ductless air conditioner.
