How to Completely Change Your Thoughts About HVAC

Welcome to my blog. My name is Betty, and I recently invested in a new heating and cooling system. It had been years since I had purchased our old system, and my husband was alive then. This was the first time selecting my own system. I did a lot of research and even considered taking our HVAC system off the grid. Now, that my house is the perfect temperature all the time, I'm ready to try something else -- so I decided to start a blog. Here, I am going to post a range of blogs on HVAC related issues as well as home repairs and other topics. I hope that you like it.

Understanding Split System Air Conditioning

by Eva Fisher

Split system air conditioning works as an alternative to window, wall or a centralised air conditioning system. Most of the time, it is called the ductless split, mini-split or the duct-free air conditioner, and it is adequate for cooling a standard home. This is without the need for any additional installation efforts and costs. Split conditioners do not need ductwork, and this lessens energy expenditures. Still, a lot of homeowners do not have enough knowledge about them and end up not choosing them.

Defining a Split System Air Conditioning?

The split system air conditioning has an indoor and outdoor unit. The installation of the unit to be located outside should be done on the rear or close to the room's exterior wall that you want to cool. The outdoor unit will have the compressor, capillary tubing or expansion coil and condenser coil. The indoor unit will house the air filter, cooling coil and long blower.


The internal thermostat controls the compressor. While the thermostat is able to detect warm air, the outdoor compressor gets activated. The compressor will circulate the refrigerant gas, adding pressure and refrigerant temperature while it compresses through a series of pipes. After that, the refrigerant will move the condenser for more processing.

Inside the condenser, the cooling system will remove the heat coming from a high-pressure gas while the gas changes its phase and turns into liquid. The chilled liquid will be pushed through the indoor tubing until the evaporator system is reached.

In your home, the evaporator fan will collect warm air, which will pass through the chamber that contains the chilled liquid refrigerant. The fan system will then blow this air, which is now cooler, back in the room, which will lower the space's overall temperature. In case the thermostat can still detect warmer air, the process will continue, and the refrigerant and excess heat pass to the outdoors again. It will go into the compressor again to start another cycle.


You can choose a multi-split system, which means more than one indoor unit is connected to the outdoor unit.

The split system air conditioning is cost-effective and efficient in cooling your home. The initial cost of this type of air conditioning unit is higher than the window type, but you will save more money on energy bills. The unit also lasts longer.

Now that you have an understanding of a split system air conditioning unit, you will not hesitate to have one installed.
