Your HVAC System Has Been Asleep Since October

Wake it up before it wakes you up — at 2am in July.

Spring HVAC startup isn't glamorous. It's filter replacements, belt checks, coil inspections, and a cooling tower that's been sitting stagnant for five months. Skip this and you're not saving time — you're borrowing it from August.

Rooftop Units (RTUs)

Filter replacements are obvious. What gets missed: dirty evaporator coils, worn belts, and refrigerant levels that drifted over winter. A unit that turns on isn't a unit that performs.

Airflow restriction caused by dirty coils means longer run cycles, higher utility bills, and accelerated wear. It also means your tenants in Suite 204 will notice before you do.

Cooling Towers

Standing water plus five months equals bacterial growth. Legionella doesn't care about your Q2 budget. Drain, clean, and treat before startup — every time. This is not optional, and it is not a place to value-engineer.

Controls & Thermostats

Setpoints drift. Schedules get overwritten. Someone always adjusted something over winter. Recommission your building automation system before tenants start complaining about the temperature.

1) Get the HVAC contractor on the calendar now

Spring scheduling fills fast. If you haven't already, call your mechanical service vendor this week. Properties that schedule early get morning appointments. Properties that wait get emergency rates.

2) Walk the rooftop before the rain

Fifteen minutes with your phone camera. Drains, RTU surrounds, any standing water or debris. If you find something, you're ahead of it. If you don't, you still have documentation.

3) Brief your tenants

If you're doing any mechanical work that affects building temperature or noise, a short email heads-up reduces complaints by about 80%. Takes three minutes. Saves an afternoon of calls.

A good HVAC partner doesn't just keep a building comfortable. They keep your phone quieter.

The best commercial mechanical vendors in DuPage County share a few things in common: they show up on time, document their work clearly, and communicate before problems become surprises.

That communication gap — between we serviced it and here's exactly what we found and what we recommend — is where most expensive surprises happen. When evaluating your vendors this spring, that documentation habit is the thing to test.

Q: “Should I be power washing rooftop equipment or is that the HVAC contractor's job?”

Great question — and the short answer is: it depends on what's being cleaned and who you ask.

HVAC technicians service the mechanical components: coils, refrigerant, electrical, controls. They're not typically cleaning RTU casings, rooftop surfaces, drain areas, or building facades around rooftop penetrations.

That's where a commercial power washing contractor comes in. Cleaning the exterior of rooftop equipment, the surface around it, and the drains that serve it is exterior maintenance — and it directly affects how efficiently your HVAC runs.

If your rooftop looks like five years of neglect, it probably is. And that accumulation is doing real work against your mechanical efficiency.
