A pre-summer maintenance guide to ensure your Mitsubishi Heavy Industries (MHI) air conditioning units run efficiently before temperatures rise.

As spring arrives and temperatures begin to climb, it’s time to get your air conditioning system ready for the warmer months ahead. Proper air conditioning maintenance ensures your Mitsubishi Heavy Industries (MHI) air conditioning unit runs efficiently, keeping your home or business cool, comfortable, and energy-efficient all summer long.

In this guide, we’ll walk you through the essential pre-summer air conditioning maintenance steps to help you avoid breakdowns, reduce energy consumption, and get the best performance from your system.

Clean or Replace Your Air Filters

One of the most important and easiest maintenance tasks is cleaning or replacing your air filters. Over time, filters collect dust, dirt, and allergens, which can reduce airflow and efficiency.

• Check your air filters every month and clean or replace them if necessary.
• A clogged filter can increase energy use, so keeping it clean helps lower bills.
• For allergy sufferers, a clean filter improves indoor air quality.

Inspect and Clean the Outdoor Unit

The outdoor condenser unit plays a crucial role in heat exchange and airflow, so keeping it free from debris is essential for peak performance.

• Remove any leaves, dirt, or obstructions around the outdoor unit.
• Use a soft brush or vacuum to clean the condenser coils.
• Ensure at least two feet of clearance around the unit for proper airflow.

Check the Refrigerant Levels

Low refrigerant levels can lead to poor cooling performance and higher energy costs. If you notice your MHI air conditioning unit isn’t cooling effectively, it may need a refrigerant top-up.

• Look for signs of leaks, such as ice buildup or hissing sounds.
  
  
• If you suspect a refrigerant issue, contact a professional HVAC technician for servicing.
  
  
• Regular maintenance can prevent costly repairs down the line.

Test the Thermostat and Controls

Your thermostat settings play a huge role in maintaining a comfortable temperature while keeping energy use in check.

• Set your thermostat to cooling mode and check if the system responds correctly.
  
  
• Consider upgrading to a smart thermostat for better control and energy savings.
  
  
• For business premises, programmable thermostats can help regulate cooling during peak hours.

Schedule a Professional Air Conditioning Service

While basic maintenance can keep your system running efficiently, an annual professional air conditioning service ensures your MHI air conditioning unit is in top condition.

• A professional technician can inspect electrical connections, lubricate moving parts, and check for system leaks.
  
  
• A pre-summer service helps prevent unexpected breakdowns during heatwaves.
  
  
• Regular servicing extends the lifespan of your air conditioning unit.

Why Prepare Your Air Conditioning in Spring?

Getting your air conditioning unit ready before summer means:

• Better energy efficiency, reducing electricity costs.
• Improved cooling performance, ensuring a comfortable home.
• Fewer chances of breakdowns, avoiding costly emergency repairs.
• Cleaner air quality, reducing allergens and pollutants indoors.

By following these simple air conditioning maintenance steps, you can ensure your Mitsubishi Heavy Industries air conditioning system is ready to keep you cool and comfortable when the hot weather arrives.

Upgrade or Replace Your Air Conditioning System

If your air conditioning unit is old or inefficient, now is the best time to upgrade to a new Mitsubishi Heavy Industries system. Modern air conditioners offer:

• Advanced energy efficiency to reduce electricity bills.
• Smart climate control for customised cooling.
• Quieter operation and better airflow for ultimate comfort.
