The standard air conditioning systems for commercial facilities in Chicagoland are packaged rooftop units, many of which are heat pumps that also provide heating during the winter. As we move into the fall, we recommend business owners assess the performance, condition, and age of their rooftop units so they can make decisions about whether it’s time to have them replaced. If commercial air conditioning repair in Chicago, IL becomes too expensive, it’s better to arrange early to have new rooftop units installed.
When should you replace a rooftop AC unit instead of repairing it?
- If the unit is 15 years old or more, repair costs often outweigh replacement costs
- Cooling performance issues (uneven cooling, high humidity) that persist despite repairs
- Noticeable rise in energy consumption or utility bills without increased usage
- Excessive noise or mechanical strain, indicating internal wear beyond repair
