Residential split systems are the modern way to efficiently heat and cool your home. Split systems utilize central air conditioning and heating units, but divide them into two parts: an outdoor unit that houses the compressor, coil and fan, and an indoor unit that contains an airstream circulation fan and an evaporator coil or blower. This setup allows for greater control over each area of the home, allowing you to customize temperatures and provide energy efficiency improvements that result in lower energy bills. With residential split systems, you can rest assured knowing you’re staying comfortable—without hurting your wallet.
