HVAC Services Kalamazoo MI | Call Kalamazoo Cooling & Heating

Protection starts with prevention. We recommend an annual HVAC maintenance check, which includes inspecting your furnace heat exchanger for cracks—a primary source of CO leaks—and ensuring proper venting. We also strongly advise installing UL-listed carbon monoxide detectors on every level of your home. Our technicians are trained to identify and repair potential CO hazards specific to older systems common in Kalamazoo neighborhoods.

First, check your thermostat settings and ensure the power to the unit is on. If it's still not working, a common issue with Kalamazoo boilers is a loss of water pressure or a failed circulator pump. You can try checking the system's pressure gauge; if it's low, you may need to repressurize it. For safety and to prevent further damage, we recommend calling us immediately. Our local team can often provide same-day emergency service to diagnose and repair your boiler heating system quickly.

Watch for unusual signs like a yellow burner flame (it should be blue), soot around the appliance, persistent strange odors, or excessive moisture on windows. For boilers, listen for kettling (rumbling or banging noises) or notice inconsistent heat between radiators. These can indicate issues ranging from a cracked heat exchanger to mineral buildup, which are serious safety and efficiency concerns. If you notice any of these, schedule a service call with us right away to keep your home safe and warm.
