In Illinois, an HVAC installation usually ranges from $5,000 to $18,000, depending on factors such as the size of your home, the type of system, and the complexity of the installation. High-efficiency systems and additional features can drive the price higher, but they often result in long-term energy savings.
An AC repair usually ranges from $150 to $2,000, depending on the issue and the specific parts that need to be replaced. Minor repairs, such as fixing a thermostat or cleaning coils, tend to be on the lower end, while more complex issues, like compressor or refrigerant problems, can push expenses higher.
