📋

Maintenance

Quarterly and seasonal RTU maintenance under planned maintenance agreements.

When should a rooftop unit be replaced instead of repaired?

Replace when the RTU is 15–20+ years old, the compressor or heat exchanger has failed, it uses phased-out R-22 refrigerant, or repair costs exceed half of a new unit. A new high-efficiency RTU with an economizer cuts energy use substantially, and because we fabricate curb adapters in-house, the replacement usually drops onto the existing curb in a single day.

How much does a rooftop unit cost in Chicago?

Rooftop quotes are free. Price depends on tonnage, gas or electric heat, efficiency, curb work and crane access, so we survey the roof, measure the existing curb and quote the complete job — unit, curb adapter, crane, gas, electrical and start-up — as one number with no surprises. Maintenance-agreement customers save 15% on parts and labor.

Do you handle restaurant HVAC and make-up air?

Yes — it is a specialty. Restaurant kitchens need exhaust hoods, make-up air and dining-room HVAC to work as one balanced system; because we design and fabricate hoods, install make-up air units and service rooftop units, one company owns the whole airflow problem. Established accounts get a 2-hour emergency response when a unit fails during service.

Commercial HVAC & Rooftop Units — Frequently Asked Questions

Which rooftop unit brands do you install?

All brands — Trane, Carrier, Lennox, York, Daikin, Rheem, Goodman and others. We recommend the best fit for your building, budget and available rebates.

How long does an RTU replacement take?

Most single-unit replacements are completed in one day, including crane lift, curb adapter, gas and electrical connections and start-up.

Do you provide rooftop maintenance agreements?

Yes. Quarterly or seasonal RTU maintenance — filters, belts, coils, refrigerant, electrical and economizer checks — under planned maintenance agreements with 15% off parts and labor.

Can you fabricate a curb adapter for a different brand unit?

Yes. Daily Work Shop fabricates custom curbs, curb adapters and transitions so a new unit fits an existing opening without roof work.

Do you service RTUs 24/7?

Yes. 24 hours a day, 365 days a year, with a 2-hour emergency response for established accounts across Chicago and the suburbs.

What is a make-up air unit and do I need one?

A make-up air unit brings tempered fresh air into a kitchen to replace what the exhaust hood removes. Chicago code requires it for most commercial hoods; without it, doors are hard to open, the dining room is drafty and the hood does not capture properly.
