How to Prepare Your AC for Texas Summer: Pre-Season Maintenance Checklist

Importance of Clean Filters for AC Performance

One of the simplest and most effective maintenance tasks you can perform is changing your air filter. Clogged or dirty filters reduce airflow, causing your AC to work harder and less efficiently. In Lewisville, Texas, where the heat can be intense, ensuring proper airflow is critical for maintaining your home’s comfort.

• Why it’s important: A clean filter improves indoor air quality, enhances system efficiency, and reduces wear and tear on your AC unit.

How to do it: Replace the filter every 1–3 months, especially during peak cooling season. For homes with pets or allergies, more frequent changes may be needed.

1. The Role of Coils in AC Efficiency

   Your AC has two sets of coils—the evaporator coil and the condenser coil. Over time, dirt and debris can accumulate on these coils, reducing their ability to transfer heat and leading to poor cooling performance.

   • Evaporator coils: Located inside the air handler, these absorb heat from the air inside your home. Dirt buildup here will cause the coils to freeze and the system to stop cooling.
   • Condenser coils: These are located outside your home and release heat absorbed by the evaporator coils. Keeping the area around the condenser clean ensures it can effectively release heat.

   How to maintain the coils:

   • Clean the condenser unit: Ensure no debris is blocking the outdoor unit. Trim any plants or branches that might obstruct airflow.

   Schedule professional cleaning: If you’re unsure how to clean the coils, it’s best to leave it to the professionals. Call Southern Comfort Mechanical for thorough coil cleaning.

Understanding Refrigerant and Its Role

Refrigerant is the lifeblood of your air conditioning system. It absorbs and releases heat, cooling your home effectively. If your AC is low on refrigerant, it can lead to inefficient cooling and increased energy costs.

Low refrigerant levels are one of the most common causes of an AC running but not blowing cold air, especially during the peak of summer.

Why You Should Check Refrigerant Levels:

• Low refrigerant levels: Could indicate a leak or undercharge, both of which can lead to system failure.
• Signs of refrigerant issues: If your AC is blowing warm air or has frozen coils, it may be time to check the refrigerant.

What to do:

Call a professional for a refrigerant checkup. Southern Comfort Mechanical will assess and recharge your system as needed to ensure optimal performance.

Ensure Accurate Temperature Control

Your thermostat controls the temperature of your home by regulating your AC system. Your thermostat must be working properly to maintain a comfortable environment.

• How to test: Set your thermostat to a comfortable temperature and check if the system responds quickly and efficiently.

The Importance of Sealed Ducts for Efficient Cooling

Leaky ducts can lead to a loss of cool air and a significant drop in your AC’s efficiency. In homes throughout Lewisville, Texas, proper ductwork inspection and sealing are vital to ensure the cool air stays where it’s needed.

• How to spot leaks: Check for visible holes or gaps in the ducts, particularly near joints.

What to do next: Call Southern Comfort Mechanical for a professional duct inspection. Our team can seal leaks and improve airflow, reducing energy waste.

Preventing organic Growth and Water Damage

Your AC unit’s condensate drain line helps remove moisture that is pulled from the air inside your home. If this line becomes clogged, it can cause water damage or lead to mold growth inside your system.

• Why it’s important: A clogged drain line can lead to water damage, mold growth, and other issues that could require costly repairs.

How to clean: Pour a mixture of water and vinegar or use a specialized cleaner to clear the line. If you’re unsure, have a professional handle it for you.
