Air Conditioning

Finding the Right Cooling System for Your Home

The most common type of air conditioning system in this area is a central forced air split-system. This system has an air conditioner or heat pump located outside of the building with either an indoor cooling coil attached to a furnace, or an indoor fan coil located in the basement or attic. Split-system central air conditioners come in a variety of efficiency ranges from 14 SEER to as high as 20+ SEER.

For areas that can’t be ducted, mini-split air conditioners are a popular choice. These consist of an outdoor unit piped to a small self-contained blower coil unit installed on the wall or ceiling. With efficiency levels as high as 26 SEER, mini-split systems can be a great choice for areas such as sun rooms, or other hard to cool areas.

Typically, over half of the energy used in your home goes to heating & cooling, so making the right decision about your home’s heating system can have a big effect on your utility bills — and your comfort. We carry a complete line of Energy Star® qualified equipment, with many systems qualifying for federal or local tax credits or rebates.

Popular Air Conditioning Systems

Central Air Conditioning Systems

Also known as a ducted air conditioning system, the central air conditioning system keeps the whole house or commercial space cool by distributing cool air through a network of ducts and vents. The ducts used by central systems can also be used to distribute heat during winter.

Mini-split Air Conditioners

Unlike central air conditioning systems, mini-split air conditioning systems do not need ducts to distribute cool air throughout a property. Instead, they are used to cool individual areas inside a house or building. The compressor and heat exchangers — the outdoor components of mini-split units — don’t have to be located directly behind the indoor portion, giving property owners the convenience of placing these outside components in a location where they will not be displayed prominently.

Packaged Terminal Air Conditioners

A Packaged Terminal Air Conditioner, or PTAC, is a self-contained, through-the wall appliance that is mounted through a hole cut into an exterior wall. They are like window units, but with no outdoor portion protruding from the wall outside.
