When you ensure your HVAC system is maintained, you won’t only be able to save money, but also energy. These essential maintenance services will also extend the unit’s lifespan, and save you money by preventing the need for early replacement. If you are unsure about how to get started or what maintenance tasks need to be done, use the information here.
Keep in mind, if you are planning on doing the maintenance yourself, you need to make sure to shut the power to the system off before getting started. If you aren’t confident in doing it yourself, then hire the professionals.
Remove Debris in and Around the Exterior Unit
The first step when maintaining your HVAC system is to remove the fan cage on the exterior compressor/condenser. You can use a wrench or screwdriver to take off the fasteners and to lift the fan grill or cage off of the top of the exterior unit. Then, you can either clean the leaves and other debris from the interior of the unit by hand, or you can use a wet/dry vacuum.
Clean the Fins
Use your garden hose and spray the fins from the inside out to blast away any dirt or debris that are between them. Don’t ever use a pressure washer to do this, since the pressure may cause damage to the fins. If you notice that the fins are especially dirty, then use a fin cleaning spray, which can typically be purchased at a home improvement store.
Straighten Out the Fins
Any reduction of air flow through your system’s fins can reduce overall efficiency. This means you need to carefully straighten any bent fins with a butter knife or a fin-straightening tool. Make sure that you do this gently so that the tubing that is embedded in the fins isn’t damaged.
Clean around the Unit
After you have finished cleaning the inside of the exterior unit, you will need to rake any debris and leaves accumulated around it. Make sure all vegetation is removed. Leave at least two feet of space in every direction to ensure proper airflow.
Clean the Evaporator Coil
You can use a soft brush to dust the coil off and remove any debris that have accumulated. Then spray the coil with a special cleaner. The liquid will drip off into the drain pain, which can be cleaned with hot water, soap, and a little bleach.
Then pour a 50/50 mixture of bleach and water down the drain. This will help clear out any dirt inside and reduce algae growth.
Change the Filter
You need to change the filter in your system regularly. If you have pets or kids, you may need to change it more often than what is recommended by the manufacturer. Also, be careful if you are using HEPA or air purifying filters since they can reduce the airflow into the system significantly.
The maintenance tips highlighted here will help ensure your system remains efficient and that it operates properly. You should also schedule professional maintenance with a professional at least once a year to ensure there are no serious issues with your system.
