HVAC Repair Chicago IL | Call G & A Heating and Air Conditioning Solutions

In Chicago, our homes are sealed tight against the cold, which can trap dust, allergens, and pollutants in the ductwork. Over time, this circulates through your living spaces. Our professional air duct cleaning service removes this buildup, which can improve your indoor air quality, help your HVAC system run more efficiently, and may even reduce allergy symptoms for your family.

This is called short cycling, a common issue for Chicago furnaces. It's often caused by an oversized unit, a dirty air filter, or a faulty thermostat. Short cycling strains your system, increases wear, and raises energy bills. Our technicians can diagnose the exact cause—whether it's a simple fix like replacing a filter or a more complex issue—and provide a lasting repair to restore proper operation.

Carbon monoxide (CO) is a serious, silent danger from cracked heat exchangers or blocked vents. We recommend an annual professional furnace tune-up, which includes inspecting the heat exchanger, checking venting, and testing for CO. Our technicians are trained to spot early warning signs Chicago homeowners might miss. We also strongly advise installing and maintaining CO detectors on every level of your home as a critical backup safety measure.
