Understanding Your AC System

A solid grasp of how your air conditioning system functions is essential for maintaining it properly and spotting potential issues before they escalate. Here’s a breakdown of the key components of your AC system and how they work together to keep your Dallas-Fort Worth home cool and comfortable:

Outdoor Unit

The outdoor air conditioning unit is typically located on the ground outside your home and plays a critical role in the heat exchange process. Here’s what it includes:

  • Compressor: This is the heart of your air conditioning system. The compressor compresses the refrigerant, which raises its temperature and pressure, enabling it to carry heat from inside your home to the outside.
  • Condenser Coil: After the refrigerant is compressed, it flows through the condenser coil where it releases the heat it’s carrying into the outside air. As the refrigerant cools, it turns back into a liquid form.
  • Fan: The fan in the outdoor unit blows air over the condenser coil to help dissipate the heat more quickly. Proper airflow is crucial for the efficient operation of the condenser coil.

Indoor Unit

Located inside your home, often in a basement or utility closet, the indoor unit is responsible for cooling your home’s air. It includes:

  • Evaporator Coil: This coil absorbs heat from your home’s air, cooling it as the air passes over. The refrigerant inside the evaporator coil evaporates as it absorbs heat, becoming a gas again.
  • Air Handler: The air handler contains a fan that circulates air throughout your home. It blows the indoor air over the cooler evaporator coil and then redistributes the now-cooled air back into your home through the ductwork.


Refrigerant is the substance that your AC system uses to transfer heat from the inside of your home to the outside. It circulates between the indoor and outdoor units, continuously evaporating and condensing in a closed loop. This cycle of evaporation and condensation is key to how your AC cools your home.


The thermostat is the control center of your AC system. It monitors the temperature in your home and tells the AC system when to turn on and off based on the temperature settings you choose. It is essential for maintaining comfort and ensuring that your AC doesn’t run more than necessary, which helps save on energy bills.

Regular Cleaning and Care

Maintaining your air conditioning system through regular cleaning and care is crucial for optimal performance, especially in the demanding climate of the Dallas-Fort Worth area. Here’s a detailed look at some essential maintenance tasks that can help keep your AC running smoothly.

Clean or Replace Air Filters

One of the easiest, yet most crucial, maintenance tasks is managing the air filters:

  • Frequency: It’s recommended to check your air filters at least once a month, especially during peak usage seasons. Replace or clean them as needed, depending on the type of filter your system uses.
  • Impact: Clean filters ensure unobstructed airflow, which is essential for the efficiency of your system. A clogged filter forces the AC to work harder to circulate air, increasing your energy bills and putting additional stress on the system, which can shorten its lifespan.
  • DIY Tip: Air filter replacement is a simple task that most homeowners can do themselves. Filters are usually accessible via a slot on the indoor unit or the return air duct.

Keep the Area Around Outdoor Units Clear

The outdoor unit of your AC system needs plenty of room to “breathe”:

  • Clearance: Ensure that there’s at least two feet of clearance around the unit. This space is necessary for adequate airflow and to allow for easy access during maintenance or repairs.
  • Debris Management: Regularly inspect the area around your outdoor unit. Remove any leaves, dirt, and debris that could obstruct the air intake. During fall and spring, check more frequently as leaves and pollen are more likely to accumulate.
  • Landscaping Considerations: Be mindful when landscaping around your outdoor unit. Avoid planting high-maintenance vegetation that could drop leaves or seeds into the unit. Opt for gravel or small stones around the base to discourage plant growth and keep the area dry.

Clean the Coils

The coils are critical components of your AC system, and keeping them clean is key to maintaining efficiency:

  • Evaporator and Condenser Coils: Over time, both sets of coils can become coated with dust, pollen, or other debris. This buildup insulates the coils and reduces their ability to absorb and expel heat.
  • Cleaning Process: For the outdoor condenser coils, you can often use a garden hose to gently wash away dirt (make sure the unit is turned off first). Indoor evaporator coils might be less accessible and require professional cleaning during your annual maintenance visit.
  • Frequency: Inspect the coils annually and clean them as needed. If you live in an area with high dust levels or have foliage nearby, you might need to clean the coils more frequently.

Seasonal Tune-ups

To ensure your AC system is ready to handle the Dallas-Fort Worth heat efficiently, scheduling seasonal tune-ups with a professional is essential. Here’s what to expect and why these check-ups are crucial:

Schedule Professional Maintenance

Professional maintenance is akin to a health check-up for your AC system. Regular tune-ups keep it running smoothly and can prevent costly breakdowns. Ideally, schedule these inspections in the early spring, just before the heavy cooling season begins. A typical professional service call from a qualified HVAC technician at BV Air Conditioning & Heating should include:

  • Checking Refrigerant Levels and Testing for Leaks: Proper refrigerant levels are vital for efficient operation. Too little refrigerant can lead to reduced cooling power and overworked components, while too much can cause damage to the compressor. Technicians will check for the correct amount and inspect for any leaks, which can be harmful to the environment and decrease the efficiency of your system.
  • Tightening Electrical Connections: Loose connections can cause erratic performance and even pose safety risks. During the tune-up, a technician will ensure all electrical components are snug and operating safely.
  • Lubricating Moving Parts: Lack of lubrication can cause increased friction in motors and bearings, leading to premature wear and tear. This simple step helps parts move smoothly, reducing electricity usage and preventing unnecessary strain on your system.
  • Inspecting the Condensate Drain: The condensate drain can become clogged with algae, dirt, and debris over time, which might lead to water damage and increased humidity levels inside your home. Clearing this line ensures that moisture collected by your AC is properly expelled outside, maintaining indoor air quality and comfort.

Check Thermostat Settings

The thermostat plays a crucial role in how effectively and efficiently your AC operates. Here’s what to consider:

  • Calibration: Ensure your thermostat is correctly calibrated to reflect the actual ambient temperature. This ensures your AC doesn’t overwork by cooling your home more than necessary or underperform by not cooling enough.
  • Upgrading to a Smart Thermostat: If you’re still using a traditional thermostat, consider upgrading to a smart thermostat. These devices offer advanced features like learning your temperature preferences and adjusting automatically to save energy. They can also be controlled remotely through your smartphone, allowing you to adjust settings on the go or monitor your home’s temperature from anywhere.
  • Energy Management: Smart thermostats provide detailed energy consumption reports, helping you understand your usage patterns and make informed decisions about how you cool your home. This can lead to significant savings on your energy bills, especially during the peak summer months when AC systems are most heavily used.

Seasonal tune-ups and thermostat management are foundational to maintaining your air conditioning system’s efficiency and reliability. These steps not only ensure your system is prepared to provide maximum comfort but also help in reducing your overall energy expenditure, making them an indispensable part of your home maintenance routine.
