A Complete Air Conditioner Maintenance Checklist

Hickory Heating and Cooling

20 August 2022

Most homeowners know their air conditioning systems should have regular maintenance to keep them running smoothly and efficiently. The best time to check your AC is in the spring before the weather heats up.

During a typical service call, professional technicians consult an air conditioner checklist to catch any problems that could affect your performance. This allows them to assess the condition of your unit and figure out the best solution.

Hickory Heating & Cooling LLC, the top HVAC contractor in Hickory, NC, wants you to know what to expect when your AC technician comes to your door. If you have any questions about the maintenance process and the condition of your air conditioner, don’t hesitate to ask. Any reputable contractor should be willing to guide you through the process and explain it in clear language.

Consultation With the Customer

A maintenance technician should not dive into an air conditioner maintenance checklist without talking to the customer about their experiences with the air conditioning system. Tell the technician about any problems you are experiencing and changes in your air conditioning usage since your last maintenance check-up.

Step 1: Changing the Air Filter

The air filter in an AC system keeps the air free of impurities that can damage the air conditioning system, wear out the blower motor, and make the air smell stale or moldy. If you have allergies, asthma, or respiratory conditions, a dirty filter could make them worse.

Step 2: Ensuring Proper Airflow

In addition to the air filter, other parts of the air conditioning system could become clogged or obstructed, preventing air from moving freely through the ductwork and around the evaporator or condenser coils.

The air conditioning system depends on the free movement of air to allow heat to dissipate outside while drawing heat into the evaporator coils for cooling to continue the cycle. If the coils become dirty or obstructed, the evaporator coils could freeze, and the condenser coils could overheat. Either way, they could sustain damage, and the air conditioner will no longer cool your house effectively.

Step 3: Making Sure Water Is Draining Properly

The indoor AC unit causes moisture to condense from the air. If that moisture cannot drain, it will cause the drain pan to overflow, flooding the area around the unit with water. The water could cause property damage, damage drywall, and promote mold growth.

An air conditioning maintenance technician will check your AC system for:

Any ice around the evaporator coils
Leaves, weeds, and branches around the outdoor AC unit
Problems with the fan blades or fan motor in the outdoor AC unit
Blockages in the ductwork

Step 4: Inspecting the Evaporator Coils

Your evaporator coils may need cleaning as often as every three months to prevent dirt buildup. If your evaporator coils freeze because of dirt and insufficient airflow, the maintenance technician will carefully thaw the coils and remove the ice to avoid damaging them. Whether or not there is ice present, the technician will clean off any dirt accumulation to ensure optimal contact with the air.

Step 5: Inspecting and Cleaning the Condenser Coils

The maintenance technician will clear away any plant material in the vicinity of the outdoor unit. Once they remove the offending vegetation, they will vacuum the coils and clean them with a solution. To prevent the condenser coils from overheating, the technician will lubricate the fan motor, check the blades, and test that the fan is working.

Step 6: Looking For Any Wiring or Electrical Problems

The air conditioner depends on wiring to connect the AC control panels and sensors to the blower and fan motors. If any connections fray or fail, the air conditioning system might stop working or behave unpredictably. At worst, a faulty connection could cause smoke, heat, or a fire.

Your AC technician will have diagnostic equipment on hand to check each circuit and repair any that aren’t working properly.

Step 7: Calibrating Sensors

If the temperature sensors in your air conditioning system fail, they could cause the system to stop working, work less efficiently, or work too hard, shortening the lifespan of your AC. The maintenance technician will check that your AC is operating well and that the air temperature it provides is in line with the thermostat reading.

Step 8: Cleanup and Performance Check

The last step of any air conditioner maintenance checklist is to test the overall performance of the cooling system and clean up any supplies, equipment, and remaining debris.

HVAC Maintenance

If you have an HVAC system, you should schedule two service calls: spring/summer servicing for your cooling system and a fall/winter service call for your heating system. Since your HVAC system uses the same ductwork to heat and cool your home, damage to the air conditioning system could cause problems for your furnace and heating system.

In addition to the air conditioner maintenance checklist, the furnace maintenance regimen includes an in-depth furnace inspection and winterization process.

If you're experiencing excess moisture or dampness in your home, you may already know the discomfort it causes. The air feels sticky, your furniture feels damp, and the risk of mold and mildew increases. This is where a dehumidifier comes in. In this guide, Hickory Heating and Cooling LLC will explain the benefits of dehumidifiers in your Hickory home. A dehumidifier not only improves comfort but also promotes a healthier indoor environment. Whether you're trying to reduce moisture or improve air quality, installing a dehumidifier can be a game-changer. Take advantage of these devices and call us to schedule a dehumidifier installation in Hickory, NC . 1. Dehumidifiers Help With Home Humidity Control in Hickory, North Carolina Controlling humidity in your home is crucial, especially in humid climates like Hickory's. High humidity can lead to a variety of issues, from increased energy bills to a growing presence of mold. A dehumidifier can address these problems by extracting excess moisture from the air, improving the overall comfort of your home. Here are some dehumidifier advantages you can expect when you invest in a dehumidifier for your home: Moisture control: Dehumidifiers help maintain optimal moisture levels, preventing rooms from feeling sticky or uncomfortable. Reduced condensation: They help reduce water droplets that form on windows, walls, and ceilings. Energy efficiency: By maintaining a consistent moisture level, your HVAC system won’t have to work harder, leading to lower energy costs. In Hickory, where summer humidity can make the indoors feel unbearable, a dehumidifier can be a relief. Whether you're facing wet weather or the humidity from cooking or showers, a dehumidifier keeps the air comfortable and fresh. 2. Dehumidifier Health Benefits: They Improve Air Quality and Reduce Mold Growth Did you know that mold thrives in areas with high humidity? With constant moisture in the air, mold can spread quickly in your home. This can negatively affect your health, especially if you're allergic or sensitive to mold spores. The health benefits of dehumidifiers are significant when it comes to mold prevention. Dehumidifiers reduce moisture levels in the air, creating an inhospitable environment for mold and mildew. Here's how they help: Improve indoor air quality: By controlling the humidity, dehumidifiers make it harder for mold spores and dust mites to thrive, improving the air quality in your home. Reduce mold growth: Lower humidity levels make it more difficult for mold to spread, which can protect your home’s structure and your health. Allergen reduction: Mold, dust, and other allergens can worsen respiratory issues, but dehumidifiers help minimize them by lowering moisture levels. If you're dealing with allergies or asthma, the health benefits of dehumidifiers are clear. They help keep your indoor air cleaner and fresher. 3. Stay Comfortable and Save Money With a Dehumidifier One of the biggest concerns for homeowners in Hickory is maintaining comfortable living conditions without high energy costs. Fortunately, dehumidifiers provide an energy-efficient solution for controlling humidity. They help your air conditioning system operate more efficiently by reducing the moisture load in the air. Here’s how a dehumidifier helps with energy efficiency: Improved HVAC efficiency: When your HVAC system doesn’t have to work overtime to cool moist air, it uses less energy. Comfortable temperatures: With the right humidity levels, your home will feel cooler, even when the temperature is high, reducing the need for air conditioning. Reduced running costs: Since your HVAC system doesn’t have to work harder to compensate for excess moisture, your energy bills could decrease.
