Heat & Cool the rooms you want to

Mini Split Heat Pumps have incredible efficiency, are long-lasting and an affordable solution for zoned air conditioning and heating in your home. The unique design of a mini split system allows for installations in older remodeled homes as well as new construction.

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. Mini Splits also dehumidify 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. These systems contain an indoor coil which, in turn, 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.

Check These Things Before Calling for Mini-Split Repair

Practically every week, on of our heat pump specialists arrives on a repair call only to find out that the problem was simple and might have been easily corrected by the owner. Before you call us, check these items to ensure you really need our professional services:

  • Remote Control Batteries: If your mini split heat pump uses a hand-held remote, check, and perhaps change the batteries.
  • Check Operating Mode: Check to make sure your system control is see to the correct mode: generally "Cooling" in summer and "Heating" in winter.
  • System Calling for Heating or Cooling?: Make sure that at least one zone is set to on and the desired temperature is set well below ambient for cooling operation, or well above ambient for heating operation.
  • Is the Power On: Check your circuit breaker to ensure that you have not had a nuisance trip and your heat pump system does have power.
  • Is the Outdoor Unit in Defrost Mode?: If you are operating in the heat mode, make sure that your system is not in “Defrost” mode. If it is, "defrost" should complete within a few minutes and heating operations should then resume.
  • Time Delay: If your breaker was off, after turning the power on, give it a few minutes: many systems have a built-in time delay.
  • Air Filters: Check your indoor unit filters. If your filters have not been cleaned lately, clean them now.
  • Contact Us for Service: If your system is still not running correctly, give us a call for prompt mini-split repair services!

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 then pumped back through a liquid line to the indoor coil and the cycle is repeated.

Mini splits contain 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 serves as a heater by absorbing heat from outdoor air and pumping it indoors. 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.
