ADC Heating and Cooling | Professional HVAC Services in Chicago, IL

Many older Chicago homes struggle with stale air and allergens. Our new HVAC installations include advanced air filtration and ventilation options designed for our climate. We can integrate systems like high-MERV filters or whole-home air purifiers that actively capture pollen, dust, and pollutants, significantly improving the air you breathe indoors, especially during peak allergy seasons or when windows are sealed tight.

Yes, a refrigerant leak is a common issue in Chicago that causes poor cooling and higher bills. Our technicians use electronic leak detectors to precisely locate the source. We then repair the leak following EPA guidelines, evacuate the system, and recharge it with the correct amount of refrigerant. This repair restores efficiency, protects the compressor from damage, and ensures your unit cools effectively all summer.

Often, repairs can effectively solve issues like uneven heating/cooling or strange noises. Key signs it might just need a repair include the system being less than 10-15 years old, a single component failure (like a capacitor or fan motor), or a minor refrigerant leak we can fix. We'll provide a honest, neighborly assessment—if a repair makes sense for your situation and budget, that's what we'll recommend.
