The best time to install an air conditioner in your home is typically in the spring or fall when temperatures are moderate. A/C installation during the summer, when temperatures are high, can lead to increased energy bills as the unit works harder to cool your home. Likewise, A/C installation during the winter can cause it to work harder to combat the cold weather and may lead to increased energy bills.
