Utilizing the basic concept that liquid expands into gas before cooling down again, various AC systems can keep your home or office comfortable year-round. Some models like geothermal heating systems also serve this function.
Packaged heating and cooling systems combine both a heater and air conditioner into one convenient unit, and connect easily with any house’s supply and return ducts through one wall hole.
Ductless Mini-Split Systems
Ductless mini-split systems (also called ductless heat pumps) are energy-efficient AC units that don’t require ductwork in your home in order to function. Available with various cooling capacities measured in British Thermal Units guide to different types of airconditioners , homeowners can select one suitable to cool their homes and rooms. Indoor units, which are typically wall-mounted, connect to an outdoor compressor via refrigerant tubing and electrical wiring. Cooled air is then distributed throughout your home or room by an outdoor fan with humidity removal capabilities. Ductless systems also offer heating in winter by drawing heat from either ground source heat sources or your existing central system.
Installing ductwork into an older home, renovated home addition or sunroom can be a costly renovation project. A ductless system allows air to be delivered directly into each room for direct conditioning without needing costly ducts.
When building a new house, installing a ductless system may be the ideal way to ensure whole-home comfort. Ductless systems are more energy-efficient than packaged systems because they do not waste energy when cooling multiple rooms at the same time; indeed, EnergyStar-rated ductless systems will further guarantee savings.
Ductless systems provide the ideal solution for hard-to-cool spaces in your house, such as garage workshops, sunrooms, second story rooms and attics that don’t have enough room for ductwork or are left without heating during wintertime. In such areas it can be challenging to stay comfortable, sometimes leading to musty odors in these hard-to-cool zones.
Central Air-Conditioning Systems
Central AC, also known as forced-air systems or ductless mini-splits, work by distributing cool air throughout your home or office using an intricate network of ducts and vents. A blower circulates this cool air while a thermostat controls temperature. Although these systems usually incur higher initial costs compared to packaged units or mini-splits, they offer cost-effective long-term solutions in homes with existing ductwork as well as greater energy efficiency than older systems.
Split AC systems like these are the most commonly utilized type of central AC, featuring an outdoor condenser/compressor unit connected to an indoor evaporator coil holding refrigerant, connected by a line set or copper tube and connected via blowers that push air through ductwork for cooling and dehumidification.
Due to their energy efficiency, affordability, and ease of installation, this type of air conditioner has become increasingly popular over other options. A model with an impressive seasonal energy efficiency rating (SEER), which measures how much cooling a device provides per watt of electricity used is optimal; minimum SEER allowed in the United States is 14, but more efficient options can reach 25 SEER ratings.
Evaporative Air Conditioners
Evaporative air conditioners rely on water evaporation to produce cool indoor temperatures, similar to what happens when you place a wet cloth over your forehead on a hot day: as its liquid evaporates it cools your head.
An evaporative air conditioner automates this basic concept in order to efficiently lower air temperatures in homes or other settings. According to this guide to different types of air conditioners, a typical machine typically includes a fan, reservoir for water storage, thick pads soaked with liquid layers for increased surface area and controls to fine tune results. When hot air comes into the machine through these cooling pads water molecules evaporate and cause its temperature to drop significantly.
Cooled air is then distributed throughout your home or business’s interior and outdoor spaces, saving both energy and money while being eco-friendly due to not using refrigerant gas or compressors that deplete earth’s ozone layer. Evaporative cooling offers many advantages both energy efficiently and environmentally.
Portable Air Conditioners
Portable air conditioners are smaller versions of window AC units that don’t need permanent installation, making them a great cooling option for homes that either cannot fit one through neighborhood restrictions or don’t have enough windows to fit them. Many portable ACs are designed to be moved from room to room easily; some even provide battery power instead of traditional electrical outlets.
Most portable ACs feature a single exhaust hose to evacuate heat and moisture produced during cooling processes, which makes installation and use simpler, cheaper and generally uses less energy. Some models even come equipped with remote controls, timers, fan settings and more for added convenience.
Portable ACs featuring dehumidifier features can significantly lower indoor humidity levels and are therefore perfect for humid areas. These units contain a reservoir that collects excess condensation water that needs to be manually emptied periodically; some even come equipped with an easily accessible bucket that can be drained when the “water full” light illuminates.
