HVAC Services Bolingbrook IL | Call O'brien Heating & Air Conditioning

Common signs include unusual noises like banging or whistling, uneven heating in your home, a sudden increase in your energy bills, or the pilot light frequently going out. These issues are common with aging systems in our climate. Our technicians can diagnose the problem, whether it's a faulty pump, a leak, or sediment buildup, and provide a reliable repair to restore safe, efficient heat.

We recommend a professional cleaning at least once a year, ideally in the spring before peak cooling season. In Bolingbrook, pollen, grass clippings, and dust can quickly clog condenser coils, forcing your system to work harder, reducing efficiency, and leading to higher bills and potential breakdowns. Regular cleaning is a key part of preventative maintenance that extends your unit's lifespan and keeps it running smoothly.
