Essential Maintenance Steps

To make sure your air conditioning system works well and lasts longer, it’s important to regularly maintain it. This involves doing certain maintenance activities that can help prevent expensive fixes, boost the system’s efficiency, and extend its life. 


Here are some key actions to ensure your AC remains in excellent condition:

  • Filter Replacement

Changing or cleaning your AC filters regularly is crucial for good airflow and system performance. You will find the filter in the return valve or air intake unit. 

If you have pets or live in a dusty place, it is recommended to change the filter every month. There are different kinds of filters such as fiberglass, vacuum, or HEPA, and each one needs regular cleaning to work properly.

  • Coil Cleaning

Dirt on evaporator and condenser coils makes them less efficient. Cleaning them regularly is important. 

Use a soft brush and special cleaner for indoor evaporator coils, and a garden hose for outdoor condenser coils. If they’re really dirty, consider hiring a professional to clean them thoroughly.

  • Refrigerant Level Check

Ensuring that your air conditioner has enough refrigerant is key to efficient operation and energy savings. Your AC won’t cool efficiently and will use more electricity if refrigerant levels are not checked often. 

This is why it’s essential to have a professional assess and fix the refrigerant amount, as this task demands specific expertise and tools.

  • Ductwork Inspection

Checking your air ducts for leaks or blockages is essential for them to work best. Leaks can increase your energy bills by allowing air to escape, and blockages can degrade the air quality in your home.  

For complicated systems or big blockages, you might need a professional to clean your ducts, ensuring better airflow and a more comfortable home environment.

  • Inspecting Electrical Components

Checking the AC system’s electrical parts, like wires, connections, and capacitors, is crucial for its safe use. If these components are not working properly, the system might not work efficiently, could break down, or even become a hazard. 

By regularly checking these parts for any wear or damage, you can fix or replace them as needed. This ensures the AC system stays reliable and safe, reducing the chance of it suddenly stopping working.

  • Testing Thermostat and Controls

It’s important to check and adjust the thermostat and system controls to make sure the AC is working right and keeping the temperature where you want it. If the thermostat isn’t working properly, it can cause the cooling to be off and lead to higher energy bills. 

By testing and calibrating the thermostat, you can make sure it’s running efficiently and catching any problems early to avoid bigger issues later on.

Professional Inspections

Regular professional inspections are essential for maintaining your air conditioner in peak condition. These inspections ensure your AC operates efficiently and prolongs its lifespan.

When to Schedule

Experts recommend having a professional check on your air conditioner in spring and fall to prepare for summer and winter. 

Regular maintenance with a trusted technician is key to keeping it running smoothly throughout the year. If your AC starts acting weird, making noises, or isn’t cooling right, get help from a pro right away.

What to Expect

During a maintenance visit, technicians check the unit, clean parts like coils and fins, and test how it works. This service usually takes 1-2 hours, depending on the AC’s condition.

While regular maintenance might cost initially, it saves money by avoiding big repairs later and won’t majorly disrupt homeowners’ daily lives.

Benefits of Expert Review

Professional technicians are crucial for AC maintenance because they can help make the unit last longer and prevent sudden breakdowns. 

They safely manage electrical parts and coolants, keeping homeowners safe. Regular professional service improves efficiency and greatly increases safety at home.


Taking care of your AC by cleaning, checking, and getting professional inspections helps it last longer and work better. Regular maintenance saves energy, keeps the air clean, and reduces repair needs. 

Understanding the balance between tackling maintenance yourself and knowing when to seek professional help is key to preventing issues. Consistently maintaining your air conditioning unit helps it operate smoothly, which conserves energy and maintains a comfortable temperature in your home all year round.
