Extend Your AC’s Life: Essential Maintenance Tips

August 27, 2025

In Whitby, Ontario, where the temperature can vary significantly, maintaining a comfortable indoor environment is essential. Air conditioning (AC) units play a crucial role in keeping your home or business comfortable year-round. However, neglecting maintenance can lead to reduced efficiency, higher energy bills, and a shorter lifespan for your AC unit. At Lazzaro Gas HVAC, we believe that regular maintenance is key to extending your AC’s life and keeping it running efficiently. Below, we’ll explore essential maintenance tips to ensure your AC system operates at its best.


1. Schedule Regular Professional Inspections


Regular professional inspections are the cornerstone of effective AC maintenance. We recommend scheduling a professional check-up at least once a year, ideally in the spring. During these inspections, our skilled technicians at Lazzaro Gas HVAC thoroughly examine your system, ensuring that every component is functioning correctly. Early detection of minor issues can prevent costly repairs or replacements down the line.


2. Change Air Filters Frequently


Air filters play a significant role in maintaining your AC’s efficiency by trapping dust, pollen, and other airborne particles. Over time, these filters can become clogged, reducing airflow and causing your system to work harder. Changing your air filters every 1-3 months, depending on usage and the presence of pets or allergies, can keep your AC running smoothly and improve indoor air quality.


3. Keep the Outdoor Unit Clean


The outdoor unit of your AC system can accumulate debris such as leaves, dirt, and grass clippings, which can obstruct airflow and reduce efficiency. Regularly inspect and clean the area around your outdoor unit. Gently remove debris from the unit itself using a garden hose, ensuring the power to the unit is off before doing so. A clear and clean outdoor unit promotes better performance and extends the life of your AC.


4. Check and Clean Coils


The evaporator and condenser coils in your AC unit play a vital role in heat exchange. Over time, these coils can accumulate dirt and reduce the system’s ability to absorb and expel heat. During professional maintenance visits, Lazzaro Gas HVAC technicians clean these coils, enhancing energy efficiency and preventing overheating that can damage your system.


5. Inspect Thermostat Settings


Ensure that your thermostat is functioning correctly and set to a comfortable temperature. An improperly set thermostat can lead to overworking your AC. Consider upgrading to a programmable thermostat for more precise control over your home’s climate. Programmable thermostats allow you to set different temperatures for different times of the day, optimizing energy usage and enhancing comfort.


6. Seal and Insulate Ductwork


Leaky or poorly insulated ducts can cause significant cooling loss, forcing your AC unit to work harder than necessary. Have a professional inspect your ductwork for leaks or inadequate insulation. Sealing and insulating ducts can greatly improve the efficiency of your cooling system, reduce energy bills, and enhance overall comfort.


7. Check Refrigerant Levels


Low refrigerant levels can impact your AC’s performance and lead to system failure. If your AC isn’t cooling effectively or you notice ice forming on the coils, it may indicate a refrigerant issue. Our experts at Lazzaro Gas HVAC can identify and rectify refrigerant problems, ensuring your system runs efficiently and effectively.


8. Monitor System Operation


Stay vigilant about how your AC system operates. Listen for unusual noises, such as squealing or grinding, which could indicate a mechanical issue. Also, note any changes in cooling efficiency or unusual spikes in energy bills. Promptly addressing these issues can prevent further damage and costly repairs.


Regular maintenance is the key to extending the life of your AC system. With these essential maintenance tips, you not only enhance your system’s lifespan but also improve energy efficiency and indoor comfort.
