As the days grow longer and temperatures rise, it’s important to ensure your HVAC system is ready for the summer. A well-maintained HVAC system keeps your home cool and allows it to operate more efficiently, saving you money on energy bills and extending the life of your unit. 

Here are some essential HVAC maintenance tips to get your system in top shape for the summer months.

Replace or Clean Air Filters Regularly 

One of the simplest yet most effective maintenance tasks is to replace or clean your HVAC system’s air filters. Dirty filters restrict airflow, forcing your system to work harder and consume more energy. They can also reduce indoor air quality, aggravating allergies and respiratory issues. 

Check your air filters monthly and replace them at least every three months. If you have pets or live in a dusty area, you might need to replace them more frequently. A clean filter ensures your HVAC system runs smoothly and efficiently, providing better air quality and cooling performance. 

Consider using high-efficiency particulate air (HEPA) filters, which can further trap smaller particles and improve indoor air quality. According to the U.S. Department of Energy, consistently maintaining clean air filters can reduce your system’s energy consumption by 5% to 15%. 

Clean and Clear the Outdoor Unit 

Your HVAC system’s outdoor unit, the condenser unit, can quickly become clogged with dirt, leaves, and debris, impeding its efficiency. Keeping it clean ensures optimal airflow and heat exchange, which is critical for effective cooling. 

Start by turning off the unit’s power. Then, use a garden hose to gently wash away dirt and debris from its fins, taking care not to damage the delicate fins. Trim any nearby vegetation to ensure at least two feet of clear space around the unit for adequate airflow. 

Check the Thermostat Settings 

Your thermostat plays a vital role in maintaining comfortable indoor temperatures. Ensuring it is set correctly and functioning properly can significantly improve your HVAC system’s performance and energy efficiency. 

If you haven’t already, consider upgrading to a programmable or smart thermostat. These devices allow you to set schedules that adjust the temperature automatically, helping you save energy when you’re not home. For example, you can set the thermostat to a higher temperature during the day when the house is empty and cool it down before you return. 

Inspect and Clean the Evaporator Coils 

Evaporator coils are a crucial component of your HVAC system, responsible for absorbing heat from the air inside your home. Over time, these coils can accumulate dust and dirt, reducing their ability to absorb heat and cool your home efficiently. 

Check the evaporator coils at least once a year and clean them if necessary. You can use a soft brush to gently remove dust or a no-rinse coil cleaner for more thorough cleaning. This maintenance task might be more challenging, so don’t hesitate to call a professional if needed. Keeping the coils clean enhances cooling efficiency and prevents potential issues such as frozen coils, which can lead to costly repairs. 

Schedule a Professional Maintenance Check 

While there are many HVAC maintenance tasks you can handle yourself, some require the expertise of a professional. Scheduling an annual maintenance check with a team of qualified HVAC technicians, such as Apple Plumbing, Heating, & Air, can help identify and address potential issues before they become significant problems. You can visit their website at ApplePlumbing.com to learn more about the different types of HVAC services they offer, such as HVAC installation, maintenance, and repair. 

During a professional maintenance check, the technician will inspect and clean various components of your HVAC system, check refrigerant levels, and ensure everything functions correctly. This proactive approach enhances your system’s efficiency and can prolong its lifespan, giving you peace of mind throughout the summer.
