The Spring Checklist for Your March AC Projects

March is perhaps the best time to start maintenance projects on air conditioning systems. If homeowners are prepared, they reduce the risk of problems when the sticky summer months arrive.

Typically, the work required will be a mix of professional and DIY tasks. We’ll dive into some springtime maintenance projects that will ensure a smooth-running air conditioning system all summer long.

Replace air filters

This may seem obvious, but replacing any faulty parts is the first step towards maintaining an air conditioner and preparing it for the summer months. Start by discarding any dirty, old air filters. A build-up of dirt and debris can block the flow of air and ultimately increase the workload of a cooling system. Replacing existing air filters with new ones can significantly decrease the risk of any wear and tear occurring to the air conditioner.

Plus, replacing an existing air filter with a high-quality filter has many benefits. While installing a filter that can manage allergens may cost slightly more, it’s beneficial in the long run.

Replace electrical parts

You should also check electrical parts such as the contactors and capacitors. These are usually the most heavily used parts of an air conditioning system and can also experience wear and tear over time. It’s best to contact an experienced professional when it comes to handling electrical components to avoid any costly or dangerous mishaps.

Replace the entire system if needed

It may be worth replacing the entire air conditioning system in some cases. If a system has been in place for over 12 years, it may be time to contact a contractor to install a brand-new air conditioner. Furthermore, if homeowners find that they are carrying out frequent repairs, it is another sign that it’s time to replace the old unit.

Use compressed air

A simple DIY trick that most homeowners can do in the springtime is clean out their AC system using an air compressor. This method helps keep general dirt and debris out of the system, ensuring that it is running smoothly. For precise results, the air compressor should have a nozzle on the end that helps blow air into a focused area of the air conditioner. Some of the places to target include the pipes, fans, and evaporator coils.

Conduct a chemical clean

Another spring-cleaning project for air conditioners is to give them a chemical clean. In some cases, corrosive materials can appear on the internal parts of an air conditioning unit, which are difficult to clear with an air compressor or vacuum. Handling chemicals can be a risky ordeal, so we highly advise caution. For this reason, it’s best to contact a professional service to complete the job. That way, the job is guaranteed to be completed to a high standard. Plus, experts can pinpoint any other issues that may need closer inspection.

Seek professional assistance

Most homeowners aren’t aware of how air conditioning units function. Therefore, hiring a professional service to maintain an AC system can have many benefits. As a consequence, they are more likely to make mistakes. While you can undertake some simpler cleaning projects, it’s best to leave the more complex tasks to the professionals.
