Boiler Maintenance & Tune Ups
Full Coverage Boiler Maintenance
When winter hits DuPage County, a well-tuned boiler means steady heat, lower bills, and peace of mind. At Hey Guy, we provide thorough boiler maintenance and professional tune-ups for cast-iron and high-efficiency (condensing) systems in Oakbrook Terrace, IL—keeping your hydronic heat safe, efficient, and reliable all season.
Why Annual Boiler Maintenance Matters
- Efficiency: Clean burners and heat exchangers help your boiler use less fuel.
- Reliability: Find issues early (ignition, circulators, zone valves) before they become breakdowns.
- Safety: Combustion and CO checks protect your home and family.
- Longevity: Annual service reduces scale/corrosion and extends system life.
What is a Boiler Tune-Up?
A meticulous checklist for hydronic performance.
Safety & Combustion Tests
We measure combustion, inspect the flue and draft, verify gas pressure, and test for carbon monoxide at the appliance and venting.
System Cleaning & Adjustments
We perform boiler cleaning (burners, flame sensor/igniter, heat exchanger surfaces), clear condensate traps/lines on condensing models, and calibrate controls.
Hydronic Health Check
We check the expansion tank, air separator/automatic vents, circulator pump operation, zone valves, and bleed radiators/baseboards for trapped air and even heat.
Water Quality & Pressure
We assess system pressure, look for signs of leaks, and make water-quality recommendations to limit scale and oxygen corrosion.
Smart Controls & Thermostat
We verify thermostat operation, setback schedules, and any outdoor reset or smart control settings for steady comfort and savings.

Frequent FAQs
How often should I schedule boiler maintenance?
Once per year (ideally in early fall) so your system is clean, safe, and tuned before the first hard freeze.
Do you service both cast-iron and high-efficiency boilers?
Yes! We maintain standard cast-iron units and condensing boilers.
Is a tune-up different from a repair?
Yes! A tune-up is preventive: cleaning, testing, and calibrating. A repair fixes an active fault (e.g., ignition, circulator, controls, leaks, etc.). If we spot a repair needed during maintenance, we’ll show you exactly what we found and the best next steps.
Do you service my neighborhood?
If you live in Chicago’s western suburbs, then most likely yes! While our main office is located in Oakbrook Terrace, we have clients all over the area from Lombard and Elmhurst, all the way down to Aurora and Bolingbrook!
Do you handle oil-fired boilers?
Yes! Oil systems are less common here, so call us with your details and we’ll guide you to the right solution.
