In the most recent survey, more than 16,000 readers who bought central air conditioning units -- including conventional systems and heat pumps -- between 2008 and 2015 reported on whether the units needed repairs. Of the nine brands of conventional central air systems listed, five have repair frequencies between 20 and 24 percent; three brands have repair frequencies of 27 percent or higher. This is an update from a previous survey that was published in 2014.
