Ductless Heat Pumps

A Heat Pump is an all-in-one heating and air conditioning system that works year-round to keep you comfortable. During warmer months, a heat pump works as a normal air conditioner. It extracts heat from inside the home and transfers it to the outdoor air. In colder weather, however, the process reverses—the unit collects heat from the outdoor air and transfers it inside your home. Even when the air outside feels extremely cold, the air still contains some heat. The heat pump pulls the heat from this cold outdoor air and sends it inside to warm your home. When there’s not enough heat in the outside air to meet the demand of the thermostat setting, an electric heater supplements the outdoor air to warm the home. Extremely efficient, this process produces two to three times more heat than the energy it uses. However, keep in mind, if you do not use much heat and you are thinking about replacing your system, a heat pump is more expensive to purchase up front and you will only receive a return on the heating portion of your investment when the system is in the heat mode. Additional electrical requirements may also come into play when switching to a straight cool/electric heat system.

HVAC- heating, ventilation, and air conditioning- It is a system that provides different types of heating and cooling services to residential and commercial buildings. Its function is to provide thermal comfort, humidity control and acceptable indoor air quality.

A ductless mini split system is composed of an indoor air handler/evaporator (fan coil), and outdoor condensing unit and an approximate 2.5-3″ conduit that accommodates the power (wiring), refrigerant line sets and a PVC condensate line (drain). s an indoor fan, referred to as the head, and an outdoor compressor unit. Many styles of air handler/evaporator (fan coil) are readily available depending upon your projects needs. Ductless units can be either 1:1 Single mini-split systems or Multi-split systems that can heat/cool multiple rooms.

Ductless split systems can replace a traditional central ducted system or be used in addition to a central ducted system. It works in much the same way as a traditional air conditioner or heat pump, using an outdoor condensing unit, indoor air handler/evaporator (fan coil) with an outdoor condenser, attached to refrigerant line sets and a condensate drain line. The condenser is installed outside the home or business typically on a code approved surface. The conduit is then run from the outdoor unit to the individual room within the structure that you choose, even an attic or garage. Depending upon the system design, the use of wall-mounted interior units, ceiling mounted units, recessed fa coils, floor mounted air handlers are then installed and secured in the appropriately desired spaces to control cooling, heating and humidity as needed and designed. One or a series of indoor units and refrigeration lines are used to transfer the cooled air from the outdoor condenser to the indoor units of your choice. It works in reverse with heated air in the winter. Units can be placed in any rooms you like and because each unit is individual, you control the specific temperature in that room instead of needing to set one thermostat for the entire house. As a result, you save money by cooling or heating only the space you are using. One of its greatest advantages is TRUE ZONING!

Most systems have a lifetime of 10 to 15 years, with gas furnaces lasting 20-25 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. If you live near bodies of water or the ocean, your system’s life expectancy may be drastically shortened due to the harsh environment. If your system is over 10 years old, you should have your system checked for maintenance or replacement.

In general, the sound generated by a ductless air handler (sometimes referred to as a head) is equivalent to whispering in a library (between 21 and 30 decibels). The sound from an outdoor unit is more like normal conversation (60 decibels) but is less than a conventional air conditioning condenser.

Installation of a ductless mini split air conditioner is more complicated than a window unit but far less complicated than installing a central air conditioner. But, don’t let that fool you. Ductless systems are very sensitive pieces of equipment and are quite unforgiving when mistakes are made. Small mistakes lead to HUGE problems with ductless systems. It is always best to have any AC system installed by licensed, trained professionals. Homeowner installations and using unlicensed individuals most often will void the manufacturer warranty on your new investment. Call us for a certified installation with one of our manufacturer trained technicians – we will make sure that the installation was done correctly. We will evacuate, pressure test, perform a thorough vacuum and charge with your system with refrigerant as needed for your particular installation followed by start up and commissioning reports on your system.
