Central Air Conditioner Links
You have many options for cooling a home. As well as conventional central air conditioners and ductless air conditioning systems, you can choose a window air conditioner for an individual room or a portable air conditioner. ConsumerSearch has separate reports on window air conditioners and portable air conditioners.
A heat pump is the closest alternative to air conditioning. Heat pumps heat homes in winter and cool them in summer. For some climates, experts recommend a combination of furnace, heat pump and air conditioning technologies. Heat pumps are not as effective as furnaces and air conditioners, so in most climates they are a single-product budget alternative to two units. The U.S. Department of Energy says that heat pumps are more effective at reducing humidity than central air conditioners. A trustworthy contractor can advise you whether a heat pump is a cost-effective and comfortable alternative for you.
Ceiling and portable fans are an obvious budget alternative to air conditioning. A combination of products and home improvement strategies may also be cheaper than air conditioning. Many websites have excellent advice. Those from government and environmental organizations are particularly useful. In most of the country, humidity bothers people as much or more than heat. A dehumidifier can help. See our report on dehumidifiers.
If you also need to replace a furnace, you can usually get a substantial discount if you also replace your air conditioning unit. We spoke to some installers who even offer free or at-cost air conditioning units for those buying and installing a new furnace unit. See our report on furnaces if you are considering replacing both at once.
