In the 100+ years since air conditioning was invented, engineering and technology advances have made them more versatile and considerably more energy efficient. As you search for the best system for your home, you may find that one of these types of refrigerated air conditioning systems works best for you.

Heat Pumps
A heat pump is a type of air conditioner that serves a dual purpose. It will cool a home as efficiently as an air conditioner will, but a heat pump will also heat it. These HVAC appliances have a reversing valve that changes the refrigerant flow from summer to winter. In the summer the refrigerant pulls the heat from the interior air and brings it outdoors. In the winter the refrigerant extracts the heat in the outdoor air and brings it inside.

Heat pumps do cost more than air conditioners, but given their dual function and high cooling and heating efficiency, they are a worthwhile HVAC appliance to consider if you live in a climate that doesn’t have severely cold winters.

Variable-Speed Air Conditioners and Heat Pumps
Variable speed air conditioners have the ability to change their running speeds based on the cooling demand. These systems use technology that senses the difference between indoor and outdoor temperatures and adjusts their running speed appropriately. They offer better indoor comfort, quieter operation, and lower energy bills, especially if the air conditioner uses a two-speed compressor. One of the most popular brands for these types of air conditioners is Trane.

A variable-speed air handler normally runs at a slower speed, which gives the system a chance to better distribute the cooled air. Although it’s running longer it uses less energy. It will also remove more airborne particles like dust and pollen. These systems start and stop slowly, a feature that allows all the cooled air in the ductwork to be blown into the rooms.

Ductless Mini Splits
These kinds of air conditioners don’t use ductwork to distribute the cooled air. They are some of the most efficient cooling systems because they blow directly from the indoor air handler, avoiding the thermal and air losses associated with conventional ductwork. Ductless mini splits are ideal solutions for cooling room additions, garages, or small standalone spaces. A larger ductless mini split can be expanded to cool an entire home.
