When First Response conducts AC maintenance, the service typically covers a comprehensive check of your system to ensure it is running efficiently and effectively.

They’ll also check the thermostat to ensure it accurately gauges and controls the temperature. Additionally, tightening electrical connections is critical to prevent potential safety hazards and improve the unit’s reliability.

Some tasks included in an AC maintenance service:

• Inspect and clean the condenser coils to ensure they are not hindering the system’s efficiency.
• Check refrigerant levels, look for leaks, and recharge if necessary to keep the system running smoothly without overworking.
• Clean and adjust the blower components to ensure proper airflow and enhance the system’s overall efficiency.
• Examine ductwork for leaks, leading to energy losses and reduced system effectiveness.
• Lubricate motors and bearings to reduce friction and prevent overheating or wear.
• Test the system’s controls and safety mechanisms to ensure they function correctly, providing safe operation.
• Clear the condensate drain line to prevent water backup and potential water damage or humidity issues.

DIY AC Maintenance Tips

One of the most effective ways to save money on professional AC maintenance is by taking proactive steps to care for your unit yourself. Regularly keeping your air conditioner free from leaves and other debris, changing its filters, and ensuring that it is serviced annually by a professional can significantly extend its lifespan and enhance its efficiency.

These simple tasks can prevent more costly repairs and reduce the need for emergency service calls. If you are not comfortable doing it yourself, please call us.

Clean the Air Conditioner

One simple way to potentially save money and prolong the life of an AC system is to keep the outdoor unit clean. During normal operation, a fan in the outdoor unit pulls air through the condenser coil. Airborne dust, dirt, and debris from nearby foliage can get lodged in the coil fins, restricting airflow and affecting performance.

• Removing debris/foliage: Trim back or clear the area of shrubs or flowers that can restrict airflow to the unit. Physically remove any leaves or other debris that has accumulated near the unit’s base or is clinging to the side of the unit.
• Vacuum the coil fins: Once you have ensured the system is disconnected from power, vacuum the coil, which wraps around most of the outside of the unit, using a soft bristle brush attachment. Most AC coils comprise refrigerant tubing and thin metal “fins” that bend easily.
• Cleaning the coil fins: Once the system is disconnected from power, clean the coil fins with coil-cleaning chemicals and use a garden hose (DO NOT use a power washer – too much pressure can bend or damage the fins). They gently rinse dirt and debris from the coil, starting at the top and moving down.
• Cleaning the evaporator coil: The indoor evaporator coil also requires airflow for proper operation. However, we recommend leaving cleaning AC coils to a licensed technician because it is typically difficult to access.

Replace the Filter

One of the most manageable air conditioner preventative maintenance tasks you can perform is cleaning or replacing your system’s air filter. The air filter for your AC system will be located in or near your indoor unit. Whether it is a basic 1-inch filter, a larger, 4-inch media filter, or a more sophisticated electronic air cleaner or purifier, the filter should be cleaned or replaced periodically. These air conditioner filters can help indoor air quality by removing airborne particles and pollutants.

They can also help keep your system operating at its peak performance by reducing the buildup of dust, dirt, and other particles from accumulating on internal components like the blower motor.

How often to change air filters depends on several factors:

• The quality and type of filter
• Environmental issues such as pets and smoke from a fireplace, tobacco or cooking
• If you or family members suffer from allergies or asthma
• How often does the system run due to thermostat settings/personal preferences
• Use of a constant fan for air circulation

It’s a good idea to check and inspect your filter at least once every 2-3 months. Some filters, such as the wider 4-inch media filters, can last up to 1 year before replacing. Whenever possible, follow your manufacturer’s recommendations for filter maintenance. In general, to clean or replace your AC system filter, follow these steps:

Turn off system power at the thermostat, the breaker box, or the power shutoff switch on/near the indoor unit.

• The exact location of the filter can vary depending on the indoor unit. Look for the filter along the sides, top, or bottom of the blower cabinet. Depending on the model, the filter may be positioned horizontally or vertically. In some cases, especially on older models, the filter may be found inside the blower cabinet.
• Once you have ensured the system is disconnected from power, remove and inspect the filter for excessive dust buildup or debris. Clean the filter with a vacuum attachment or replace it with a new filter.
• Ensure the filter is positioned correctly and the airflow arrows point in the correct direction.
• Replace the cabinet cover and restore power.

Prepare for Winter

Preparing your air conditioner for winter is essential, mainly if your heating system includes a furnace that shares components like the blower motor with the AC unit. Ensuring your air conditioner is well-maintained in the spring can significantly enhance the performance and efficiency of your heating system during the colder months.

One crucial step is to schedule a professional maintenance check in the spring; this ensures your AC is ready for the summer and confirms that it’s in good shape to support your furnace in the winter. Additionally, setting your thermostat correctly when transitioning to heating mode is vital. If you have a furnace, ensure the thermostat is switched from cooling to heating and set to an efficient, comfortable temperature that won’t overwork the furnace, keeping your home warm and reducing wear on the system.

AC Maintenance Can Provide Many Benefits

Improved energy efficiency

A well-maintained AC can run more efficiently, reducing energy consumption by up to 15% and lowering utility bills.

Improved air quality

Regular maintenance can reduce allergens, dust, mold, and other air pollutants, helping keep your family safe and healthy.

Longevity

Regular maintenance can extend the lifespan of your AC system. Most AC systems last 10–15 years, but neglecting maintenance can shorten their lifespan by 50%.

Fewer repairs

Regular maintenance can help prevent issues before they become critical, reducing the number of emergency repairs needed.

Peace of mind

Regular maintenance can give you peace of mind, knowing your AC system won’t break down when needed.
