Whole home air conditioners are not necessarily inexpensive, especially since they also require additional costs for professional installation. According to the website Cost Helper, the cost for both the air conditioning unit and installation can run between $3,000 and $8,000. The units are primarily sold through contractors and dealers.
Air conditioners typically run well under most circumstances, but they do require regular maintenance and cleaning. You'll need to clean the air filter and condenser coils on a regular basis and must deal with issues such as leaks or poor airflow. In addition, the air conditioner should be inspected by a professional contractor at least once a year for professional cleaning and repair. This may also mean additional costs.
While many newer air conditioners are quieter than their predecessors, almost all air conditioners are noisy to some extent. Some homeowners may find the noise annoying, especially at night or if small children are sleeping. The air conditioner unit may also rattle if placed on an unstable surface or near other flexible surfaces that vibrate when the unit is operating.
Running an air conditioner can drive up home utility costs, particularly during periods of especially hot or humid temperatures when the air conditioner is likely to be run more often. According to the Energy Star website, heating and cooling costs can average about $1,000 per year for the typical homeowner. While this can be lowered by using the air conditioner less often, running an air conditioner versus not using one will have an effect on your home energy costs.
