A reliable conditioning system is crucial throughout summer. As the temperatures rise, it’s important to make sure your unit is in tip-top condition. A poorly functioning air conditioner makes for an uncomfortable home, and it could also increase your utility bills significantly. 

Air conditioning systems come under increased pressure during extreme temperatures. To make sure your appliance is running at its peak, you should perform year-round maintenance. However, it is important to know how to maintain your system during high-usage periods to ensure a comfortable home and keep utility costs at a minimum. 

While some air conditioning maintenance can be carried out by a homeowner, hiring a professional HVAC technician to handle more significant repairs and maintenance is often beneficial. Here are the most important air conditioning maintenance tips to know for the summer. 

1. Clean the Filters

Air filters need to be changed regularly. Depending on the appliance, it could be as frequently as every three weeks. A common misconception is that people assume if they don’t use their air conditioner often, they don’t need to change the air filters as regularly. However, the reality is that if you don’t use your system much, dust, pollen, and other airborne allergens tend to gather and clog the filters. These pollutants are then dispersed around your home when the system is switched on. 

Some filters are designed to be cleaned, meaning you can extend their lifespan. Check the filter packaging for instructions on how to clean it. Typically, you can use a brush vacuum attachment and warm soapy water. While those who are less sensitive to allergens and pollutants may be resistant to these airborne contaminants, you must remember that they can also damage the air conditioner itself, causing the motor to overwork. 

Consult the owner’s manual and ensure that filters are changed regularly, especially as your system is being used more often during the summer.

2. Clean the Condenser Coils

Air conditioner condenser coils are important components for transferring heat. When dirt, dust, and other debris collect on coils, they become insulated, which reduces efficiency during the heat transfer process. Before summer, take a look at the coils in your unit and clean them if necessary. 

To clean the coils, ensure that your air conditioner is switched off. Spray the coils with a small amount of water and use a soft cloth to wipe away the dirt and dust. This keeps your unit in good condition and increases its efficiency.

3. Refill Refrigerant if Necessary

Air conditioners use refrigerant liquid (Freon™) to cool the air in your system. After years of use, refrigerant levels run low. Occasionally, there are leaks within the piping that cause the refrigerant to run out even faster. Signs that your refrigerant levels are low include a malfunctioning or inaccurate thermostat and warm air being dispersed instead of cool air.

Recharging refrigerant is relatively straightforward and only takes a few minutes. However, Freon™ is a hazardous material so exercise caution if you’re taking on this task yourself. It’s often more beneficial to hire a trained professional to recharge your refrigerant.

4. Clear Obstructions from Exterior Unit

The outside unit of your air conditioner must be kept clear of obstructions. After spring, vegetation and grass may have grown around the appliance, obstructing the airflow. This prevents the air conditioner from functioning properly and is likely to increase your utility costs. Inspect the unit regularly and ensure there is nothing gathered around it. 

As a rule, avoid planting trees or plants within two feet of the outside unit. This gives adequate space for the air conditioner to draw air from outside your home, contributing to increased temperature control.

5. Invest in a New System

At some point, every air conditioning unit reaches its expiry date. Although many systems can last up to 20 years, they often deteriorate much quicker from a lack of use and poor maintenance. If your system no longer works very well, it may be time to upgrade. 

Modern air conditioners are far more efficient than those from 10 to 20 years ago. Ductless systems are some of the most efficient on the market and take up a minimal amount of space. Investing in a Mitsubishi mini split system can give you custom temperature control for specific rooms within your home, allowing you to set different temperatures for various zones.

A Mitsubishi air conditioner comes with a choice of warranties. The standard 5-year warranty covers the parts for five years but protects the compressor for seven. If the system is installed in a residential single-family home and registered within 90 days of the installation, the owner can protect the parts and compressor for 10 years. If the system is installed in the same circumstances but registered by a Diamond Contractor or Ductless Pro within 90 days of installation, the parts and compressor can be warranted for 12 years.

At ComfortUp, we offer extended warranties on Mitsubishi products with no deductibles. This allows you to have peace of mind for an additional 3-, 5-, 7-, or 10-year period.
