There are many options when it comes to buying and choosing HVAC systems. The most common one being the split system heating and air conditioning system. You find them in businesses and in residential homes. They are called split systems because they have components that are located inside and outside. Split systems cool refrigerant to create cool air and can have a gas furnace to produce heat. They are normally inexpensive and very efficient.
The indoor air is circulated by ducts and assisted with evaporator coils or fan coils. The system is controlled using a thermostat. Newer systems allow you to control your thermostat via an app on your smartphone, so you can be in control of your temperature even if you are away from your house or business.
A Hybrid heat split system is even more energy efficient because they utilize a heat pump. The pump has the capability to heat or cool refrigerant and is completely electrically powered. If you are attempting to heat or cool a large area, a duct free split system used with a split system can get push cold air or heat into hard to reach areas. If you do not have the space for a split system, packaged heating and AC systems are a viable option. They use a simple single unit, an AC or heat pump that merges with a fan coil or evaporator coil. It is a perfect alternative for temperature control in a small space.
