Mechanical Services

Commercial HVAC for buildings and businesses

Mechanical work is the equipment layer of a building: the rooftop units, boilers, pumps, air handlers, exhaust and make-up air that keep a space usable. When that equipment goes down, the business goes down with it, so the priority is a fast, accurate diagnosis and a realistic plan rather than a parts-swapping exercise.

We service and install commercial heating and cooling equipment throughout Des Plaines and the Chicagoland area for offices, retail, restaurants, warehouses, light manufacturing and multi-unit residential buildings.

For property managers and facility teams

If you are responsible for several buildings, the value is in predictability and paperwork. We document what was inspected, what was repaired and what we expect to need attention next, so you have something to show an owner or a board when you request a capital expense.

Visits can be consolidated across properties to keep scheduling and invoicing simple, and we are comfortable coordinating access with tenants and on-site staff.

Rooftop units, boilers and pumps

Rooftop packaged units carry most of the load in commercial buildings around here, and they fail in familiar ways: compressors and capacitors, economizer linkages, belts and bearings, condenser coils packed with cottonwood, and controls that were never commissioned properly. Boilers, circulators and pumps in older buildings need their own attention — low-water cutoffs, expansion tanks, zone valves and seals.

We repair what should be repaired and replace what has reached the end of its service life, with equipment sized for the load the building actually has today rather than what it had when the original unit went in.

Equipment planning and replacement budgeting

The least expensive equipment replacement is the one you plan. We can inventory what is installed, note approximate age and condition, and give you a straightforward sense of what is likely to need replacement in the next few years so it can be budgeted rather than absorbed as an emergency.

For renovations, build-outs and changes of use, we help work out what the space will need before the drawings are final — capacity, venting, gas and electrical service, and where the equipment can practically go.

Preventive maintenance and service agreements

A maintenance agreement puts filter changes, coil cleaning, belt and bearing checks, refrigerant verification, combustion checks and control calibration on a schedule. Agreement customers also get priority scheduling, which matters most on the first hot day of summer and the first hard freeze of winter, when everyone calls at once.

Where the work allows, maintenance and larger repairs are scheduled after hours or on weekends so your operation is not interrupted.

Larger residential mechanical systems

Bigger homes often carry commercial-grade complexity: multiple furnaces or air handlers, several zones, boilers for radiant floors, secondary water heaters and recirculation loops. The same crews that service commercial equipment handle these systems, and the same maintenance logic applies — a documented schedule beats waiting for the failure.
