Summer in Spring, Texas, is no joke. When the heat and humidity soar, the last thing you need is for your AC to give up the ghost. But before you panic and start dialing emergency AC repair numbers, take a deep breath. Many common AC problems have simple solutions.

Majestic AC is here to help you troubleshoot those cooling woes. We’ve compiled the top 5 reasons your AC might be struggling and what you can do about it.

1. A Dirty Air Filter is Choking Your System

Think of your air filter as your AC’s lungs. A clean filter allows for proper airflow, ensuring cool air circulates freely throughout your home. A dirty filter, however, restricts airflow, making your system work harder and less efficiently. This can lead to:

  • Reduced cooling: Your AC struggles to push cool air through the clogged filter, leaving your home feeling stuffy and warm.
  • Frozen evaporator coils: Restricted airflow can cause the evaporator coils to freeze, further hindering cooling and potentially damaging your system.
  • Increased energy bills: Your AC has to work overtime to compensate for the lack of airflow, leading to higher energy consumption.

The Fix:

  • Check your filter monthly. Hold it up to the light. If you can’t see through it, it’s time for a replacement.
  • Replace your filter every 1-3 months. This timeframe can vary depending on factors like pets, allergies, and the type of filter you use.
  • Consider upgrading to a higher-MERV filter. These filters trap more particles but may require more frequent changes.

2. Your Thermostat Needs a Check-Up

Your thermostat is the brain of your AC system. It tells your unit when to turn on and off and what temperature to maintain. A malfunctioning or incorrectly set thermostat can cause a variety of cooling issues.

  • Incorrect settings: Ensure your thermostat is set to “cool” mode and that the temperature is set lower than the current room temperature.
  • Dead batteries: Some thermostats require batteries. If the display is blank or unresponsive, try replacing the batteries.
  • Wiring issues: Loose or damaged wiring can prevent the thermostat from communicating with your AC unit.
  • Old age: Older thermostats can become less accurate and reliable over time.

The Fix:

  • Double-check the settings: Make sure the thermostat is set to “cool” and the temperature is set appropriately.
  • Replace batteries: If applicable, replace the batteries in your thermostat.
  • Consider a smart thermostat: Upgrading to a smart thermostat can offer more precise temperature control, programmable schedules, and remote access.
  • Call a professional: If you suspect a wiring issue or your thermostat is old and unreliable, contact Majestic AC for assistance.

3. Refrigerant is Low or Leaking

Refrigerant is the lifeblood of your AC system. It’s the substance that absorbs heat from your home’s air and releases it outside. If your system is low on refrigerant or has a leak, it won’t be able to cool effectively.

  • Signs of a refrigerant leak: Hissing or bubbling sounds coming from your AC unit, ice forming on the refrigerant lines, or a noticeable decrease in cooling performance.
  • Environmental concerns: Refrigerant leaks can be harmful to the environment.

The Fix:

  • Call a professional: Refrigerant leaks require specialized equipment and expertise to repair. Contact Majestic AC for prompt and reliable service.
  • Consider a system upgrade: If your system is old and uses an outdated refrigerant, it may be more cost-effective to upgrade to a newer, more environmentally friendly model.

4. Your Outdoor Unit is Dirty or Obstructed

Your outdoor unit (condenser) plays a critical role in releasing the heat absorbed from your home. If it’s dirty or obstructed, it can’t function properly, leading to reduced cooling.  Common culprits are dirt, debris, leaves, grass clippings, and even overgrown shrubs can block airflow and hinder heat dissipation.

The Fix:

  • Clear the area: Remove any debris or vegetation surrounding the unit. Maintain at least two feet of clearance on all sides.
  • Clean the fins: Use a soft brush or a garden hose with a gentle spray to clean the condenser fins. Be careful not to bend the fins.
  • Schedule professional maintenance: Majestic AC can perform a thorough cleaning and inspection of your outdoor unit to ensure optimal performance.

5. Electrical Issues Are Short-Circuiting Your Cool

Your AC system relies on a complex network of electrical components to function. Problems with wiring, capacitors, or the fan motor can prevent your system from cooling properly.

Signs of electrical issues include burning smells, unusual noises coming from the unit, or the system frequently tripping the circuit breaker.

The Fix:

  • Check the circuit breaker: If the breaker has tripped, reset it. If it trips again, there may be a more serious electrical problem.
  • Call a professional: Electrical issues can be dangerous. Contact Majestic AC for safe and effective repairs.
