A & R Heating & Air Conditioning | Licensed HVAC Repair in Milwaukee, WI

Common signs include a yellow or flickering flame instead of blue, soot around the furnace, excessive moisture on windows, or a stale, stuffy smell. Since carbon monoxide is odorless, it's crucial to have your furnace inspected annually by a certified technician like ours at A & R Heating & Air Conditioning. We check for cracks in the heat exchanger, proper ventilation, and install CO detectors to keep your Milwaukee home safe.

Ice buildup on your outdoor unit often indicates issues like low refrigerant levels, blocked airflow from dirty filters, or a malfunctioning defrost cycle. In Milwaukee's cold climate, this can strain your system and lead to breakdowns. Don't try to chip the ice off yourself—it can damage coils. Our technicians at A & R Heating & Air Conditioning will diagnose the root cause, recharge refrigerant if needed, and ensure proper defrost operation to prevent future ice problems.

For Milwaukee homes, we recommend biannual maintenance: a furnace check in fall to prevent carbon monoxide risks and an AC tune-up in spring to avoid ice buildup. Our service includes cleaning components, testing safety controls, checking refrigerant levels, and ensuring efficient operation. This proactive care from A & R Heating & Air Conditioning helps extend your system's life, improve energy efficiency, and reduce emergency repairs during extreme weather.
