Essential Tips for Servicing Your AC: Keeping Cool and Efficient

As temperatures rise, ensuring your air conditioning (AC) system is in optimal condition becomes crucial. Regular servicing not only extends the lifespan of your unit but also enhances its efficiency, helping you stay cool without spiking your energy bills. Here are some essential tips on how to service your AC to keep it running smoothly and efficiently.

“Energy efficiency is the fastest, easiest way to save energy and money.” – Ernest Moniz, an American Nuclear Physicist and former Government Official

Clean or Replace Air Filters Regularly

One of the simplest yet most effective maintenance tasks is cleaning or replacing the air filters. Dirty filters can obstruct airflow, reducing the system’s efficiency and allowing dirt to accumulate in the system, potentially causing overheating. Inspecting the air filter every month, according to the blog, Spring Cleaning: Air Filters, is a good practice to get into – making it easier to keep track of when to switch out. Depending on your AC model and usage, filters should be cleaned or replaced every three months.

Steps to Clean/Replace Air Filters:

• Turn off the AC unit.
• Locate the filter compartment, usually found behind the return air grille or within the unit itself.
• Remove the filter and inspect it for dirt and debris.
• For reusable filters, rinse them with water and let them dry completely before reinstalling.
• Replace disposable filters with new ones if they appear clogged or damaged.

Inspect and Clean the Coils

The evaporator and condenser coils are vital components of your AC system. Over time, they can collect dirt, reducing their ability to absorb and dissipate heat. Keeping these coils clean ensures efficient operation and prevents strain on the system.

Steps to Clean the Coils:

• Turn off the AC unit and disconnect the power supply.
• Access the Condenser coil outside (usually behind the outdoor unit).
• Use a soft brush or a vacuum cleaner with a brush attachment to remove loose dirt and debris.
• For stubborn dirt, apply a coil cleaner and let it sit for the recommended time before rinsing with water.
• Indoor coils should be cleaned by a professional to prevent any accidental damage to drains, pipes and cables.

Check the Thermostat Settings

Ensure your thermostat is working correctly and set at a comfortable temperature. Consider upgrading to a programmable thermostat if you don’t already have one. This allows you to set temperature schedules that align with your daily routine, enhancing energy efficiency.

Thermostat Maintenance Tips:

• Replace the batteries if the thermostat is not hardwired.
• Keep the thermostat away from heat sources like direct sunlight or appliances.
• Regularly dust and clean the thermostat’s components.

Examine the Condensate Drain

The condensate drain allows moisture collected from the air to be expelled outside the unit. Over time, algae and mould can clog the drain, leading to water damage and increased humidity levels in your home.

Steps to Clear the Condensate Drain:

• Locate the drain line, typically a PVC pipe.
• Use a wet/dry vacuum to remove any blockages.
• Pour a mixture of bleach and water (1:1 ratio) into the drain to prevent algae and mould growth.
• Ensure the drain is clear and water flows freely.
• If you cannot access the drain pipes easily, consider upgrading to a serviceable drain connection to allow easy cleaning.

Inspect the Ductwork for Leaks

Leaky ducts can lead to significant energy loss, making your AC work harder to cool your home. Regularly inspecting and sealing any leaks in the ductwork can improve efficiency and reduce energy costs. Also, fixing air duct leaks, as mentioned by the blog, How to Check Air Ducts for Leaks, saves you money and helps your home stay comfortable as it prevents air from leaking into parts of your home that you don’t need to cool.

Ductwork Inspection Tips:

• Check for visible tears or holes in the ducts.
• Feel for air escaping from joints or seams.
• Use silver tape or duct tape cover any leaks.
• Consider professional duct cleaning and sealing services if needed.

Ensure Proper Insulation

Insulating your home and ductwork helps maintain the desired temperature without overworking your AC unit. Proper insulation minimises heat gain during summer and heat loss during winter, contributing to overall energy efficiency.

Insulation Tips:

• Check the insulation levels in your attic, walls, and floors.
• Add or replace insulation where necessary.
• Ensure the ductwork in unconditioned spaces (like attics and crawl spaces) is properly insulated.

Maintain the Outdoor Unit

The outdoor condenser unit requires sufficient airflow to operate efficiently. Ensure the area around the unit is clear of debris, plants, and obstructions that could impede airflow.

Outdoor Unit Maintenance Steps:

• Trim any vegetation within two feet of the unit.
• Remove leaves, dirt, and debris from the unit’s exterior.
• Clean the fins with a garden hose, being careful not to bend them.
• Ensure the unit is level to avoid operational issues.
• If the unit is close to a fence or obstruction an air deflector should be installed to allow the air to properly ventilate from the outdoor unit. Magnetic Airbenders can be purchased from Clean Air Living.

Schedule Professional Maintenance

While many maintenance tasks can be done by homeowners, scheduling regular professional maintenance is essential for comprehensive care. HVAC technicians can identify and fix potential issues before they become major problems, ensuring your system runs efficiently.

Professional Maintenance Checklist:

• Inspect refrigerant levels and adjust if necessary.
• Replace refrigeration caps, seal valves.
• Check for and repair any leaks.
• Test and calibrate the thermostat.
• Inspect electrical components and connections.
• Lubricate moving parts.
• Clean and inspect the blower motor and fan.

Monitor Energy Usage

Keeping an eye on your energy bills can help you detect any sudden increases in consumption, which might indicate an issue with your AC system. Regular monitoring allows you to address problems promptly and maintain efficiency.

Energy Monitoring Tips:

• Compare your energy usage month-to-month and year-to-year.
• Invest in an energy monitor to track real-time consumption.
• Address any unusual spikes in energy use by scheduling a professional inspection.

Stay Informed

Understanding your AC system and staying informed about best maintenance practices can help you keep your unit in top shape. Regularly reading the user manual, attending to minor issues promptly, and staying updated on new maintenance techniques can make a significant difference.
