Mini Splits

Stay comfortable all summer & winter

Mini Split Heat Pumps have incredible efficiency, are long-lasting, and are an affordable solution to zoned cooling and heating in your home. The unique design of the mini split system allows for installations in older remolded homes as well as new construction. R-Mech offers mini split service relied upon in and around Kansas City

Mini Split for Cooling

In the winter, a mini split draws heat from the outside air and circulates it into your home. In the summer, it reverses the process and draws heat from your interior air and releases it outdoors. It also dehumidifies the indoor air as it cools it.

The mini split serves as an air conditioner by absorbing heat from indoor air and pumping it outdoors.

How these Systems Work to Cool Your Home
  • The mini split contains an indoor coil which contains a very cold liquid refrigerant. As indoor air passes over the indoor coil, the refrigerant-cooled coil absorbs heat from the air and so quickly cools that air.
  • The cooled air cannot hold as much moisture as it did at a higher temperature. The excess moisture condenses on the outside of the coil, resulting in the dehumidification of the air.
  • The cooled, dehumidified air is then forced (by a fan) to circulate throughout the space.
  • At the same time, the absorption of heat by the refrigerant turns the refrigerant from a liquid into a vapor.
  • A compressor pumps the heat laden vapor through a vapor line to an outdoor coil which discharges the heat extracted from the indoor air.
  • As the heat is discharged, the vapor is cooled and changes back into a liquid refrigerant.
  • The refrigerant is pumped back through a liquid line to the indoor coil and the cycle is repeated.

Mini Split for Heating

The mini split contains a reversing valve which reverses the flow of refrigerant and thus allows the mini split to serve as a heater during cold weather.

A mini split system serves as a heater by absorbing heat from outdoor air and pumping it indoors.

How these Systems Work to Heat Your Home
  • As the outdoor air passes over the outdoor coil, heat from that air is absorbed by the refrigerant contained inside the coil.
  • The absorption of heat changes the refrigerant from a low-temperature liquid to a low temperature, low-pressure vapor.
  • The vapor then passes through a compressor where it is compressed into a high pressure, high temperature vapor.
  • The hot vapor then circulates into the indoor coil.
  • As indoor air passes over the indoor coil, it absorbs heat from the coil. The warmed air is then redistributed through the space.
