Arlington Heights mixes a dense, walkable downtown of mid-rise residential, retail and restaurant buildings with office and medical buildings along its main roads and industrial and flex space toward its southern edge.
Mixed-use downtown buildings are their own HVAC challenge. Ground-floor restaurants need kitchen exhaust and make-up air that doesn’t fight the systems upstairs, rooftops are crowded and hard to reach, and work has to happen without disrupting tenants and storefronts below.

Q&AQuestions
Arlington Heights commercial HVAC questions.
Answers specific to Arlington Heights. For more, see all 36 commercial HVAC questions.
Gas smell? Leave the building, don’t touch switches, and call the gas utility or 911 from outside. CO alarm? Get everyone out and call 911. No heat in freezing weather? Call us, and never use ovens or grills indoors for heat.
How do you replace a rooftop unit on a crowded downtown building?
With planning. A downtown change-out usually involves a crane, a scheduled lot or street closure, a curb adapter if the new unit has a different footprint, and coordination with the electrical and roofing trades.
Velocity HVAC-R plans the lift, the curb and the controls together so the unit goes up, connects and runs in as short a window as possible.
What matters most for HVAC in medical office buildings?
Ventilation, filtration and humidity, along with comfort. Exam and procedure rooms need enough outside air, filters suited to the system, and humidity kept in a reasonable range year-round.
We check that the equipment delivers what it was designed to and that maintenance keeps it there.
