Generally, your air conditioner should be serviced at least once a year, ideally before the peak cooling season. If your air conditioning unit is over 10 years old, you might want to consider servicing your air conditioner every 6 months — once in spring and once in autumn. Older units are more prone to wear and tear, and regular check-ups can help extend their lifespan and maintain efficiency.
Recommended Servicing Frequency
Annual Professional Maintenance
Most HVAC experts recommend having your air conditioning system professionally serviced once a year.
The best time for this is during the spring, before the cooling season kicks into high gear. This annual tune-up will prepare your system for the summer months and help catch any potential issues before they become major problems.
Biannual Maintenance for Older Units
If your AC unit is over 10 years old, you might want to consider biannual maintenance—once in the spring and once in the fall. Older units are more prone to wear and tear, and regular check-ups can help extend their lifespan and maintain efficiency.
Monthly Homeowner Checks
In addition to professional servicing, you should perform basic checks on your AC system every month.
This includes changing the air filter, inspecting the thermostat, and checking the outdoor unit for debris. Regularly cleaning vents and listening for unusual noises can also help you catch small issues before they escalate.
Why Regular Air Conditioning Maintenance Is Important
Your air conditioning system works tirelessly to combat hot summers and keep your home cool. It battles against intense heat and humidity, constantly cycling refrigerant to extract warmth from your indoor air. This continuous effort puts a strain on its components, making regular maintenance crucial for peak performance.
Regular maintenance ensures:
Optimal Performance: Prevents breakdowns, improves efficiency, and reduces energy consumption.
Extended Lifespan: Regular check-ups can help identify and address potential issues early on, prolonging the life of your unit.
Cost Savings: Regular maintenance can help you avoid costly repairs in the long run.
What Does Air Conditioning Maintenance Involve?
Maintenance typically involves a series of checks and tasks to ensure your system is operating efficiently and safely. While some tasks can be handled by homeowners, professional maintenance is essential for thorough cleaning, inspections, and repairs.
Basic Maintenance Checks You Can Perform
While some maintenance tasks should be left to professionals, there are a few simple checks you can do yourself to keep your air conditioning in good shape.
Change the Air Filter: Regularly replace your air filter every 1-3 months, depending on usage and filter type. This will help prevent dust buildup and maintain efficient airflow. A clogged filter can reduce cooling efficiency and increase energy consumption. Most filters are located in the indoor unit, often behind a return air grille. You simply slide the old filter out and replace it with a new one of the same size.
Inspect the Thermostat: Ensure your thermostat is working correctly and set to the appropriate temperature. If you have a programmable thermostat, check the settings to make sure they match your daily schedule.
Clean the Outdoor Unit: Clear any debris or obstructions around the outdoor unit (condenser) to ensure proper airflow. Make sure there's at least two feet of clearance around the unit to prevent overheating. If you find any plants or objects encroaching on this space, trim them back or move them away.
Clean Vents and Registers: Regularly clean vents and registers to remove dust and dirt, which can restrict airflow and reduce cooling efficiency. Wipe them down regularly to ensure your system can distribute air efficiently.
Listen for Unusual Noises: Listen for unusual noises like banging, rattling, or hissing. These could indicate underlying issues such as loose parts or refrigerant leaks that require professional attention. Normal operating sounds should include a gentle hum from the fan and compressor.
Professional Air Conditioning Servicing and Maintenance
While the tasks above are great for regular upkeep, professional maintenance goes a bit deeper. Here’s what a technician typically checks during a service visit:
Refrigerant Level Check/Recharge: Check that refrigerant levels are adequate for optimal performance and ensure there are no leaks. Low refrigerant can reduce cooling efficiency and damage the compressor.
Electrical Component Inspection: Checks for wear or damage in wiring, contacts, capacitors, and relays.
Coil Cleaning: Removes dirt and grime from the evaporator and condenser coils to improve airflow and heat exchange.
Drain Cleaning: Prevents water damage and high humidity by clearing the condensate drain, which is responsible for removing the moisture your unit extracts from the air.
Belt and Motor Inspection: Ensures these components are in good condition to prevent breakdowns, including tightening or replacing them if necessary.
Additional Tips for Air Conditioner Care
Even without professional assistance, you can take proactive steps to maintain your air conditioner's efficiency and ensure comfortable temperatures throughout the year.
Use a Programmable Thermostat: A programmable thermostat is a smart investment. It allows you to set temperatures to match your daily routine, so your air conditioner isn't working overtime when you're not home. This saves energy and reduces wear and tear on your system.
Choose a High-Quality Air Filter: Think of your air filter as your air conditioner’s first line of defence. A high-quality HEPA filter traps more dust, pollen, and other airborne particles, keeping your air cleaner and your system running more efficiently. Remember to check and replace your filter regularly, especially during periods of heavy use.
Schedule Professional Maintenance Annually or Biannually: Even if your air conditioner seems to be running fine, an annual or bi-annual check-up is essential for optimal performance and longevity.
Address Issues Promptly: Don't ignore unusual noises, leaks, or reduced cooling. Contact a professional for prompt repairs.
Noticeable Issues Requiring Professional Attention
If you experience any of the following symptoms, it's time to call in a professional air conditioning technician:
Ineffective Cooling: If your home isn't reaching your desired temperature, even with the air conditioning running, it could indicate a problem.
Unusual Noises or Smells: Strange sounds like banging, rattling, or screeching, along with unpleasant odours, are potential signs of underlying issues. Early detection can prevent further damage and costly repairs.
Frequent Cycling: If your air conditioning unit is turning on and off frequently (short cycling), it could strain your system and increase energy bills.
Water Leaks: Puddles around your outdoor unit suggest a possible refrigerant leak or clogged drain, requiring immediate attention.
Final Thoughts
By following these guidelines and scheduling regular maintenance, you can ensure your air conditioning system operates efficiently, reliably, and comfortably throughout the year. Remember, investing in proper maintenance now can save you money and hassle in the long run.
