HVAC Repair Chicago IL | Call Harrington Construction Services

Chicago's urban environment, with its pollen, dust, and pollution, combined with summer humidity, causes grime to build up on your outdoor unit's condenser coils. This acts like a blanket, forcing your system to work harder, increasing energy bills, and risking a breakdown. Our service includes a thorough cleaning using professional-grade solutions to safely remove debris, restoring proper airflow and system efficiency to handle our hot, humid summers.

Frozen components, like evaporator coils, are often caused by restricted airflow (from dirty filters or blocked vents) or low refrigerant levels—issues exacerbated by our cold winters. Yes, it should be treated as urgent. A frozen system can't heat your home and running it can damage the compressor. We'll safely thaw the unit, diagnose the root cause (like a leak or airflow problem), and perform the necessary repair to get your heat reliably restored.

We strongly recommend a bi-annual preventative maintenance plan. In spring, we focus on cooling: cleaning condenser coils, checking refrigerant, and ensuring your AC is ready for summer. In fall, we focus on heating: inspecting heat exchangers, checking airflow, and calibrating your furnace for winter. This proactive approach directly targets the dirt and strain that lead to the most frequent local breakdowns, saving you money on emergency repairs and high energy bills year-round.
