Inspect and Replace Filters Regularly

A clogged or damaged filter can significantly reduce your air conditioner’s efficiency and lead to increased energy consumption and potential damage to your equipment. To ensure optimal airflow and performance, inspect your filters at least once a month and replace them as needed.

1. Check for Visible Dirt and Damage: Carefully remove the filter and examine it for dirt buildup and potential damage. A clogged filter can inhibit airflow and cause your system to work harder, decreasing efficiency.

2. Replace Filters as Needed: If your filter is visibly dirty or damaged, replace it immediately. Most disposable filters need replacement every 1-3 months, while some reusable filters can last longer with proper cleaning and maintenance.

Clean and Inspect Your Outdoor Unit

Your outdoor unit or condenser plays a crucial role in dissipating the heat absorbed from your home’s indoor air. A dirty or blocked outdoor unit can reduce efficiency, leading to increased energy consumption and potential system failure.

1. Remove Debris and Obstructions: Visually inspect your outdoor unit for leaves, branches, and other debris that might obstruct airflow. Keep a clear space of at least 2 feet around the unit to facilitate optimal heat dissipation.

2. Clean the Condenser Coil: Gently clean the condenser coil using a soft brush or a garden hose, taking care not to damage the delicate fins. Ensure the unit is off before cleaning and allow it to dry completely before turning it back on.

Schedule Professional System Inspection and Maintenance

Partnering with Climate Experts for a professional system inspection and maintenance can help identify and resolve potential issues before they escalate, ensuring optimal performance and efficiency throughout the summer season.

1. System Check and Calibration: Climate Experts will inspect your HVAC system, calibrate your thermostat, and check the refrigerant levels to ensure everything is operating optimally.

2. Inspect and Clean Internal Components: During professional maintenance, technicians will examine and clean your system’s internal components, such as the evaporator coil, blower motor, and electrical connections, which can all impact system performance.

Check and Seal Your Ductwork

Your HVAC system’s ductwork can harbour air leaks, leading to decreased system efficiency and a waste of energy. Ensuring your ductwork is sealed can significantly improve your system’s performance and reduce energy costs.

1. Look for Visible Signs of Leaks: Examine your ducts for visible signs of leaks, such as gaps, tears, or disconnected sections.

2. Seal Leaks and Cracks: Seal any identified leaks and cracks in your ductwork with mastic sealant or metal-backed tape. Ensure connections at vents and registers are secure and properly sealed.

Upgrade to a Programmable or Smart Thermostat

Using a programmable or smart thermostat can help you optimize your air conditioning for maximum efficiency, reducing energy consumption and costs during the summer season.

1. Set Customized Cooling Schedules: A programmable thermostat allows you to create customized cooling schedules based on your daily routine, ensuring your home stays comfortable while minimizing energy waste.

2. Optimize Temperature Settings: Smart thermostats can learn your preferences and adjust the temperature accordingly, maximizing comfort and efficiency. They can also provide valuable insights into your home’s energy usage patterns, helping you make informed decisions on energy consumption.


Preparing your HVAC system for the summer season is a vital task to maintain a comfortable and energy-efficient home. By inspecting and replacing filters, cleaning your outdoor unit, scheduling professional system inspections and maintenance, sealing ductwork, and upgrading to a programmable or smart thermostat, you can ensure optimal HVAC performance and prevent potential system breakdowns during the hottest months of the year.
