Heed These Signs You Need AC Repair

Throughout the summer, homeowners may experience issues with their systems and be looking for AC repair in Collierville, TN. Recognizing the signs that your AC needs repair is essential to prevent breakdowns and ensure your comfort during the hottest months.

How do you know when your system is in need of repairs? Here are a few key signs that indicate your AC requires professional attention and repair.

Increased Energy Bills

A sudden spike in your energy bills without a logical increase in power usage could be a sign of a malfunctioning AC system. Aging or inefficient AC systems use more energy to provide the same cooling output. As AC units age, their efficiency can decline due to wear and tear, outdated technology, and reduced performance of components such as compressors and motors.

An AC system that is too large or too small for the space it’s cooling can be another reason for reduced efficiency. An oversized unit might cool the space quickly, but turn off before adequately dehumidifying the air. An undersized unit will run longer but struggle to maintain the desired temperature.

Weak Airflow and Lack Of Cooling

There are a multitude of reasons for this issue. One of the most common causes is a dirty or clogged air filter. Dirty filters restrict the airflow making it harder for the AC system to push air through. This can lead to reduced cooling efficiency and uneven temperature distribution. Similarly, blocked or closed air vents can prevent airflow and stop cool air from reaching the desired areas of your home.

Another possibility is the evaporator coils inside the indoor unit have frozen. If this happens, they won’t be able to absorb heat effectively, leading to weak airflow and reduced cooling. Other possible issues are low refrigerant levels, dirty condenser coils, leaky ducks, or an undersized AC unit. Consult a professional to determine which issue you’re experiencing.

Strange Noises

Strange noises coming from an air conditioning unit can be a sign of various issues, ranging from minor concerns to potentially larger problems. These are a few noises that may be reason for concern.

  1. Rattling or Banging
  • Loose components such as fan blades, screws, or bolts, can cause rattling or banging noises when the AC is running.
  • Foreign objects that find their way into the unit, such as leaves or twigs, can cause rattling as the fan blades hit them.
  1. Squealing or Screeching:
  • If the blower motor belt is loose, worn, or misaligned, it can produce a squealing or screeching noise.
  • Worn or damaged blower motor bearings can also create high-pitched noises.
  1. Clicking or Tapping:
  • Some clicking or tapping noises are normal during the AC’s start and stop cycles.
  • Clicking sounds can also occur due to electrical issues such as relay problems.

Paying attention to these signs can help you catch AC issues early and avoid major breakdowns or costly repairs. Regular maintenance and prompt AC repair are essential to keep your system running smoothly, maintain energy efficiency, and ensure your comfort throughout the year.
