While your heating system may be the last thing on your mind during the warmer months, summer is actually the perfect time to give it the attention it needs. Regular off-season maintenance ensures that your system stays efficient, reduces the risk of breakdowns, and helps you avoid costly repairs when you need heat the most. Here are the key steps to maintaining your heating system during summer.

1. Schedule a Professional Inspection

One of the best things you can do for your heating system is to schedule a professional inspection. A certified technician will thoroughly examine the unit, checking for worn-out components, cleaning internal parts, and testing system performance. This preventative measure helps detect small issues—like minor leaks or dirty burners—before they turn into expensive repairs in the middle of winter.

2. Clean and Replace Filters

Dirty or clogged filters force your system to work harder, reducing efficiency and increasing wear and tear. Replace disposable filters or clean reusable ones according to the manufacturer’s instructions. Doing this during summer helps improve airflow and keeps your system running smoothly year-round.

3. Check and Refill Heating Oils

If your system runs on heating oils, summer is an ideal time to check the oil levels and refill if necessary. Old or contaminated oil can lead to clogs and reduced efficiency. Keeping your oil fresh and tanks full also helps prevent moisture buildup, which can cause rust or corrosion inside the tank.

4. Adjust Your Thermostat Settings

Set your thermostat to a higher temperature or switch it to a summer mode to prevent the system from running unnecessarily. Consider installing a programmable or smart thermostat to automate temperature adjustments, which can save energy and reduce strain on the system.

5. Clean Around the Unit

Keep the area around your heating unit clean and free of debris. Remove dust, pet hair, and clutter that may have built up over the winter. A clean environment improves airflow and reduces the risk of fire hazards.

6. Test the System Briefly

Even during summer, it’s wise to run your heating system briefly to ensure it’s operating correctly. This can help you catch unusual noises, smells, or signs of malfunction early on. According to the U.S. Energy Information Administration, in the winter of 2022–2023, about 4.96 million households in the United States used heating oil (distillate fuel oil) as the main space-heating fuel.

By taking the time to maintain your heating system during the off-season, you’ll ensure a warmer, more efficient, and stress-free winter. Do you need heating oils for your energy system? Contact ABC Fuel Oil Co. Inc today for a free estimate.
