What Our Boiler Services Include

From a quick seasonal tune-up to a full system replacement, McNally’s offers comprehensive boiler services designed to keep your Montgomery home warm and your energy bills in check. Boilers that receive regular maintenance simply perform better and last longer, which is why we recommend scheduling a checkup before the heating season kicks in.

Here’s what we typically cover during a boiler service visit:

  • Thorough inspection of burners, heat exchanger, and venting components
  • Checking and calibrating pressure and temperature controls
  • Flushing and bleeding radiators or baseboard units as needed
  • Testing safety valves and system controls
  • Identifying and addressing any signs of corrosion or wear

When a repair or full replacement makes more sense than continued maintenance, we walk you through your options clearly and honestly. Our goal is to help you make a well-informed decision, not to upsell you on something you don’t need. Be sure to check our current promotions for any available savings on boiler services or new installations.

Frequently Asked Questions

How often should I have my boiler serviced in Montgomery, IL?

Most boiler manufacturers and HVAC professionals recommend an annual tune-up, ideally in early fall before the heating season begins. Given how hard Montgomery winters can push a heating system, staying on a regular maintenance schedule helps catch small issues before they turn into bigger problems. Schedule a service visit with McNally’s to get on the calendar before the cold sets in.

What are signs that my boiler needs repair or replacement?

Common warning signs include unusual noises like banging or kettling, uneven heat distribution throughout your home, a sudden spike in your heating bills, or visible signs of corrosion or leaking around the unit. If your boiler is more than 15 to 20 years old and requiring frequent repairs, replacement is often the more cost-effective path. Our team can assess your system honestly and help you weigh your options.

Does McNally's install new boilers in homes around Oswego and Aurora too?

Yes, McNally’s Heating and Cooling serves Montgomery and the surrounding communities including Oswego, Aurora, and North Aurora. If you’re in the area and need a new boiler installed or your current system evaluated, we’re happy to help. Reach out to schedule a visit at your convenience.

Is a boiler more efficient than a forced-air furnace for heating my home?

Boilers and furnaces both have their strengths, and the right choice depends on your home’s layout, existing infrastructure, and personal comfort preferences. Boilers circulate hot water through radiators or baseboard heaters, which many homeowners find produces a more consistent, comfortable heat with less air circulation. If you’re weighing your heating options, our technicians can walk you through the pros and cons based on your specific situation.

What should I do if my boiler stops working in the middle of winter?

If your boiler goes out during a cold Montgomery winter, don’t wait. McNally’s offers emergency HVAC services to help get your system back up and running as quickly as possible. In the meantime, check your thermostat settings, make sure the pilot light is lit if applicable, and verify that your circuit breaker hasn’t tripped.
