The right type of air conditioner for your home depends on the size of the space you are trying to cool. Here at GSM Services, we specialize in installing and repairing many different types of air conditioning systems.
Central air conditioning systems still represent the gold standard for home air conditioning. In most cases, the ductwork system that delivers cool air throughout the house will distribute heated air during winter months. A central air conditioning system is not sized by BTU output. Instead, cooling capacity is given in “tons.” A “ton” of cooling capacity equals the amount of heat absorbed by one ton of ice melting over a 24-hour period (roughly equal to 12,000 BTU).
Great gains in comfort and energy savings are possible when you replace an old central AC system with a new, high-efficiency unit. For example, a 10-year old AC system may only be operating at under 10 SEER, while new units are available that operate above 20 SEER. When air conditioning maintenance and repair isn’t providing the comfort or savings you want, it’s time to consider upgrading to new equipment. GSM Services will also help you evaluate building envelope improvements that help to reduce your air conditioning requirements.
Ductless mini-split air conditioners are usually designed to provide heating as well as air conditioning. In terms of cooling capacity, these units represent the middle ground between portable and whole-house air conditioning systems. However, this AC type typically has higher SEER ratings (greater efficiency) than other AC options.
The compact exterior module for a ductless air conditioning unit delivers refrigerant to an equally compact, wall-mounted air handler that blows conditioned air throughout a room. No unsightly window installation is required. Ductless units are sized by BTU. Larger units can supply refrigerant to more than one indoor air handler.
Consider ductless air conditioning if your home has no ductwork, if you need to cool an addition or converted attic, or if you like the super-efficient heating and cooling these systems can provide.
Portable air conditioning units are small enough to be purchased and installed by the homeowner. In the portable air conditioning category, you’ll find window units that are totally self-contained and floor models that need to be ducted to a window. Most portable air conditioners use refrigerant just like whole-house systems. A smaller number are “evaporative air conditioners” that provide cooling by evaporating water.
Portable air conditioners are sized by BTU (British Thermal Unit) output, with sizes ranging from 5,000 to 10,000 BTU. These appliances should also have EER and SEER ratings that measure energy efficiency (see sidebar).
Portable air conditioning units are much less expensive than other cooling equipment; but, remember that you’ll need multiple units to cool an entire house. Also consider the extra noise in each room and the fact that when installed, a window-mounted unit blocks the view and natural ventilation.
