Cooling your home is a relatively straightforward process. Central air conditioners accomplish this by converting the hot air that is outside your home into the cold air that is then pumped throughout your house using the condenser coils. Central air conditioners are one of the most common types of air conditioning units available on the market today.
If, for whatever reason, a central air unit doesn't appeal to you, there are other ways that you can cool down your home without having a bulky unit that sits outside your house. Below are a few of the "alternative" ways to cool down your home that you may not have thought of before. If you have any questions, contact an HVAC company that is familiar with these types of units to discuss your next AC installation.
The idea of a geothermal system is a relatively new concept; and these systems work by driving long pipes into the ground and using the energy from the earth to cool down your home. One of the main advantages to this is the fact that a geothermal system can both heat and cool your home depending on what time of year it is, so you won't need an independent furnace in the wintertime. In addition to this, the energy savings are substantial. The only energy that is actually needed is what you need to power the motor, which means that once the original cost of a geothermal AC installation is covered, you should reap the financial benefits for years to come.
In years past, you used to have to install a bunch of ductwork to cool down any kind of expansion onto your home, or you would have to install a window unit that doesn't always match with your interior decor. Now, you can cool your home down using a ductless mini split that is attached to an exterior wall, which will convert hot air directly into cool air through a pipe, or you can install one on an interior wall and integrate it into your existing AC system. Ductless mini splits are not cheap, but there are a lot less expensive than installing vent systems and ductwork to only extend your system a few more feet and cool down an auxiliary space.
While this type of unit is not technically that different from a central AC system, variable air units have one major difference to your standard AC unit: the ability to change energy consumption. Similar to the way that dual-stage furnaces work, a variable air system will operate at a lower power level for regular temperatures, but when the numbers start to go up, it'll switch on a higher gear to tackle the hotter weather. Conventional AC systems can only ever turn on or off, while variable air systems can save a significant amount of energy by operating at different speeds.
