When Chicago summers turn up the heat, your air conditioning system becomes your best friend. But without proper care, that friendship can quickly sour — leading to higher energy bills, poor cooling, and expensive repairs. At Chicago Comfort HVAC Services, we believe prevention is better than cure. With the right maintenance routine, you can keep your AC running smoothly, extend its lifespan, and ensure year-round comfort.
Here are the top 7 AC maintenance tips every homeowner should follow.
1. Replace or Clean Your Air Filter Regularly
One of the simplest yet most important maintenance tasks is checking your air filter. A clogged filter restricts airflow, forcing your AC to work harder and consume more energy.
- When to Replace: Every 1–3 months, depending on usage and indoor air quality.
- Benefits: Improved efficiency, better air quality, and reduced wear on your system.
Our team at Chicago Comfort HVAC Services can recommend the best filter type for your system and lifestyle.
2. Keep the Outdoor Unit Clear of Debris
Your AC’s outdoor condenser unit needs adequate airflow to operate efficiently. Over time, leaves, grass, dirt, and other debris can build up around it.
- Tip: Keep at least 2–3 feet of clearance around the unit.
- Seasonal Care: After storms or heavy winds, check for debris.
By keeping the area clear, you ensure optimal heat exchange and prevent unnecessary strain on your AC.
3. Schedule Annual Professional Tune-Ups
Even the most hands-on homeowner can’t replace the value of a professional inspection. During a yearly AC tune-up, our certified technicians:
- Clean coils and components
- Check refrigerant levels
- Inspect electrical connections
- Test thermostat calibration
- Lubricate moving parts
Annual maintenance not only boosts efficiency but also helps detect issues before they turn into costly repairs.
4. Clean the Evaporator and Condenser Coils
Dust and grime buildup on your coils can reduce the system’s ability to absorb and release heat. This forces your AC to work harder, increasing energy consumption.
- DIY Care: Gently rinse coils with a garden hose (low pressure) and remove large debris.
- Professional Care: Have coils thoroughly cleaned during your annual tune-up.
At Chicago Comfort HVAC Services, we use industry-approved methods to clean coils without damaging delicate fins.
5. Check and Clean the Condensate Drain
The condensate drain removes moisture collected during the cooling process. Over time, algae and dirt can clog the drain, causing water leaks and humidity issues.
- DIY Method: Flush with a mixture of warm water and mild soap or vinegar.
- Warning: If you notice persistent water pooling, call a professional.
A clean drain prevents mold growth and protects your home from water damage.
6. Optimize Thermostat Settings
Your thermostat plays a big role in how efficiently your AC runs.
- Ideal Summer Setting: Between 74°F and 78°F when you’re home, higher when away.
- Upgrade Option: Install a programmable or smart thermostat to automatically adjust temperatures based on your schedule.
A properly set thermostat can significantly cut cooling costs without sacrificing comfort.
7. Inspect Ductwork for Leaks and Blockages
Leaky or clogged ducts can waste cooled air, forcing your system to work harder. Signs of duct problems include uneven cooling, higher bills, and visible dust around vents.
- DIY Check: Look for disconnected sections or gaps in accessible duct areas.
- Professional Fix: Our team can seal leaks and clean ducts for improved airflow.
Well-maintained ducts ensure you get the most out of your AC’s performance.
