Did you know that maintained units, especially 6-10 ton rooftop units, can last 15-20+ years, while ignored units may fail in 7-9 years.

All commercial units, at minimum require professional maintenance twice a year (biannually), ideally in the spring and fall.

Regular, proactive service ensures efficiency but more importantly extends the 15-20 year lifespan of the unit, and prevents costly, unexpected downtime.

Do you need reliable monthly filter change outs or an automatic start up and winter service? At CAS we offer maintenance contracts custom to your business’s needs.
