An air conditioning system is an investment that should serve you for many years. Regular air conditioner maintenance not only helps you avoid costly repairs but also improves the system’s efficiency. Chicago and its surrounding areas experience a highly variable climate, which can accelerate wear and tear on HVAC equipment. To extend the lifespan of your air conditioner and ensure trouble-free operation, it’s essential to follow a few proven guidelines.
1. Regular Air Filter Replacement
Air filters are one of the most critical components of an HVAC system. Their primary function is to capture dust, pollen, and other contaminants that can reduce system efficiency. Neglecting air filters can lead to:
- Reduced airflow,
- Increased energy consumption,
- Excessive strain on the compressor.
To prevent these issues, it’s best to replace air filters every 1-3 months, depending on how frequently the air conditioner is used. Clean filters also ensure fresh, high-quality indoor air for your home.

2. Professional Air Conditioner Service at Least Once a Year
Even a well-maintained air conditioning system requires regular check-ups to ensure longevity and efficiency. A professional air conditioner service not only detects and resolves minor issues before they become major problems but also optimizes the entire system’s performance. A comprehensive inspection includes:
- Cleaning Coils and Fans
Regular removal of debris and dirt from the evaporator and condenser coils helps maintain proper airflow. Clean coils enhance cooling efficiency and reduce energy consumption by several percent. Fans must also operate without obstructions to ensure proper air circulation, which minimizes compressor strain.
- Checking Refrigerant Levels
Incorrect refrigerant levels can lead to decreased cooling efficiency and excessive energy usage. A professional service will precisely measure and, if necessary, refill the refrigerant, ensuring optimal system performance. Maintaining proper refrigerant pressure is also essential for preventing compressor overload and prolonging system lifespan.
- Electrical Wiring Diagnostics
The condition of electrical wiring and connections is crucial for system safety and stability. During an inspection, specialists check for insulation damage and ensure all connections are secure. Early detection of potential electrical issues helps prevent short circuits, power surges, and even fire hazards. Regular diagnostics significantly enhance the reliability of your HVAC system.
Additionally, technicians can conduct advanced diagnostic tests, including temperature sensor calibration and an analysis of energy consumption for individual system components. These tests help detect hidden issues that could eventually lead to significant failures.
It’s recommended to schedule a professional service at least once a year, ideally in spring before the air conditioner is used intensively during the summer. This ensures a comfortable indoor climate while minimizing the risk of unexpected, costly repairs during peak demand. Regular maintenance is an investment in a system’s long-term, trouble-free operation, leading to lower energy bills and reduced operational costs.
By working with local specialists like New Comfort Heating and Cooling, you can arrange convenient service agreements. Long-term cooperation with a trusted technician ensures comprehensive service and annual maintenance reminders.

3. Keeping the Outdoor Unit Clean
The outdoor air conditioning unit is exposed to dirt, such as dust, leaves, and small branches. These contaminants can restrict airflow and cause the system to overheat. To prevent these issues:
- Regularly clear debris around the unit,
- Clean the metal fins of the heat exchanger,
- Avoid covering the unit with decorations or plants.
Given Chicago’s unpredictable weather, it’s also important to remove snow from outdoor units during heavy snowfall.
4. Optimal Temperature Settings
Excessive strain on an air conditioning system shortens its lifespan. Setting the temperature too low can lead to premature wear of system components. The recommended indoor temperature is around 72-78°F (22-26°C). Additionally, you should:
- Use a programmable thermostat,
- Avoid sudden temperature changes,
- Keep doors and windows closed while the air conditioner is running.

5. Hiring Professionals for Installation and Repairs
Improper installation can result in leaks, refrigerant flow issues, and other technical problems. Professional air conditioner installation and air conditioner repair help avoid unnecessary costs and breakdowns.
