How To Clean HVAC Coils: Tips For Maintaining Peak Performance

The home’s HVAC (Heating, Ventilation, and Air Conditioning) system provides ultimate comfort during all seasons. While this system works efficiently, there are some ifs and buts that exist with it. The HVAC coils are delicate and may be subject to damage sometimes. Dirt, dust, and other waste materials can stick to it and hamper its functioning. This causes a silent decrease in its performance without anyone noticing it.

But, not to worry – there is a solution to keep the HVAC coils in top shape. It is to ensure that the heating and cooling system lasts long and works well. Let’s learn more about HVAC service and how it leads to better functioning. Prepare to simplify HVAC coil care and make your home’s HVAC system run better while saving energy.

Reasons To Clean HVAC Coils?


HVAC coils are essential for the heat change process. They either cool or warm up the air that moves through the system. Dirty coils can significantly impact the system’s efficiency and lead to a range of issues, including:

  • Dirty and junk build-ups act like blockers. They lower the coil’s ability to move heat well. This makes the HVAC system use more energy.
  • A system with dirty coils uses more power to reach the desired temperature, using extra energy and making your utility costs grow.
  • Dirty coils can help grow mold and bacteria. These things may spread into your home areas as well. It can cause breathing problems and allergies, making the air inside bad to breathe.
  • Dirty coils can put a lot of pressure on a system and wear it out early. This higher the chances that the system will have problems or break down entirely.

Tips For Maintaining HVAC Coils For Better Functioning

Now that we know why cleaning HVAC coils is crucial, let’s look at some tips to clean them for your system to run well.

Regular Inspection

Begin by checking your HVAC system regularly with your eyes. Look for any dirt, dust, or trash on the coils. If you see a big pile up, it is time to plan for cleaning. However, ensure the power to your HVAC system is off before you start any cleaning. It is vital for your safety and to stop the system from getting spoiled when you clean it.

Remove Debris

Use a brush or vacuum cleaner to gently clean away any obvious mess from the coils. Be careful so you don’t break the fragile fins on the loops.

Use The Coil Cleaner

Get a good coil cleaner that is made for HVAC systems. These cleaners are made to break up and get rid of tough dirt or grime from the coils. Use the instructions given by the manufacturer to apply and mix the cleaner correctly.

Clean With Water

Once you have put on the coil cleaner, wash it off with water. This assists in getting rid of any leftover cleaning stuff and makes certain that the coils are clean and set to work their best.

Straight Bent Fins

Check the fins on the coils for any bending or harm. If you see any bent fins, carefully fix them using a fin comb. This part is crucial for keeping the coils working well with the air.

Call For Professional Maintenance


Sometimes, homeowners can do a few cleaning and care tasks. However, it is best to have professional HVAC maintenance done at least once every year. A trained helper can check, find possible problems and clean deeply with special tools. They can utilize their extra skills too.

Keep Changing Air Filters Regularly

Unclean air filters can help create a pile of trash on HVAC coils. Get into the habit of changing or cleaning your air filters often so you can keep good airflow and not make it hard on the coils.

Monitor Your Surroundings

Ensure the space around your HVAC machine is neat. Cut plants or leaves that might stop the air from reaching the system. Doing this easy thing can stop dust and rubbish from piling up on the coils.

Invest In UV Lights

Look at putting in UV lights in your HVAC system. These lights are made to kill bacteria and mold. It stops them from growing on the coils. UV lights can be an excellent addition to your HVAC cleaning plan.

Check Refrigerant Levels

Always watch the coolant levels in your heating and cooling system. When the refrigerant is low, it can make coils freeze up. This stops them from working well. If your cooling or heating isn’t working well, get a professional to check the refrigerant and refill it.

Monitor Thermostat Settings


Watch your thermostat settings closely so they match what you need for your comfort. Making regular changes and a good thermostat help your HVAC system stay in good shape. It stops extra work on the coils that could damage them over time.

Consider Coil Coatings

Check out the possibility of using coating on pipes to give a shield against dirt and trash. These coverings can lessen the build-up of dirt on coils, making them last longer and needing deep cleaning less often.

Seal Ductwork Leaks

Bad ducts can let in dust and dirt into the HVAC system. It adds to coil clutter. Fix any holes or gaps in your ducts to keep them clean and work better, making everything run smoother while stopping dirt from getting onto the coils.

Learn About DIY Maintenance


Learn the simple HVAC care tasks that can be done at home. It is essential to have experts do regular cleaning, but knowing how to change air filters and check coils helps with taking care in between professional checks.


Taking time to keep your HVAC coils clean and working well is worth it for making your heating/cooling system last longer. By using these tips, you can ensure your HVAC system works really well. This will keep it comfortable for many years while saving energy too. Routine care helps you save on energy costs and also makes your home’s air healthier. Don’t wait until your HVAC system starts to have problems, make coil maintenance a priority now.
