How to Maintain Your Furnace During Summer

May 8, 2024

As the temperatures rise during the summer months, many homeowners may forget about their furnace or heater until colder weather returns. However, it is important to continue maintaining your furnace even during the summer to ensure that it remains in optimal condition for when you need it again. In this blog, we will discuss how to care for your furnace during the summer months to prevent potential issues and extend its lifespan.

How to Care for Your Furnace During Summer

When it comes to maintaining your furnace during the summer, there are several key steps you can take to keep it in good working order. By following these simple tips, you can help prevent costly repairs and ensure that your heating system is ready to go when you need it.

Clean or Replace Air Filters

One of the most important maintenance tasks for your furnace is to clean or replace the air filters regularly. Dirty or clogged filters can restrict airflow and cause your furnace to work harder, leading to higher energy bills and potential system failures. During the summer months when your furnace is not in use, it is a good time to check the filters and clean or replace them as needed. This simple task can improve airflow, indoor air quality, and overall efficiency of your heating system.

Check the Thermostat

Another important step in maintaining your furnace during the summer is to check the thermostat. Make sure that it is working properly and set to the appropriate temperature. Consider upgrading to a programmable thermostat if you do not already have one, as it can help you save energy and money by automatically adjusting the temperature based on your schedule. By ensuring that your thermostat is in good working order, you can prevent unnecessary strain on your furnace and promote energy efficiency.

Inspect and Clean Ductwork

During the summer months, when your furnace is not in use, it is a good time to inspect and clean the ductwork. Over time, dust, debris, and other contaminants can accumulate in the ducts, reducing airflow and affecting the overall performance of your heating system. Consider hiring a professional duct cleaning service to remove any buildup and improve the air quality in your home. Keeping your ductwork clean can also help prevent potential health issues and prolong the lifespan of your furnace.

Schedule a Professional Inspection

To ensure that your furnace is in good working condition, it is recommended to schedule a professional inspection and maintenance service during the summer months. A certified HVAC technician can check for any issues, clean components, lubricate moving parts, and perform necessary repairs or adjustments to keep your furnace running smoothly. Regular maintenance can help prevent unexpected breakdowns and extend the lifespan of your heating system, saving you money in the long run.

Check for Any Unusual Smells or Sounds

It is essential to pay attention to any unusual smells or sounds coming from your furnace, even during the summer months when it is not in use. Strange odors or noises could indicate a potential problem with the system that needs to be addressed promptly. If you notice any unusual smells, such as a burning or musty odor, or hear any loud or unusual noises, it is best to contact a professional HVAC technician to investigate and resolve the issue before it escalates into a more significant problem.

Cover and Protect Outdoor Unit

If your furnace includes an outdoor unit, it is essential to cover and protect it during the summer months when it is not in use. Covering the unit with a weatherproof tarp or cover can help prevent debris, dirt, and moisture from infiltrating the system and causing damage. Additionally, keeping the outdoor unit clean and free of debris can improve airflow and prevent potential issues when you turn your furnace back on in the fall. Taking these simple steps to protect your outdoor unit can help extend the lifespan of your heating system and improve its overall performance.


Maintaining your furnace during the summer is essential to ensure that it remains in good working condition and ready for use when colder weather returns. By following these simple tips, you can care for your furnace, prevent potential issues, and extend its lifespan. From cleaning or replacing air filters to scheduling a professional inspection, taking proactive steps to maintain your furnace can save you time, money, and stress in the long run.
