Top 5 Signs Your AC Needs Immediate Repair This Summer

Summer heat can be relentless, and a fully functioning air conditioning (AC) system is essential to maintain comfort and safety. Knowing the signs that indicate your AC needs repair can save you from discomfort and high repair costs. Here’s a detailed guide on the top 5 signs your AC needs immediate attention and steps to improve your HVAC system's performance.

1. Unusual Noises Coming from the Unit

Hearing strange sounds like grinding, squealing, or banging from your AC? This is one of the most obvious indicators that something is amiss. These noises often signal issues with internal components such as belts, motors, or fans.

Example: Imagine settling down for a movie night, only to hear a persistent squeal from your AC. It’s distracting and often points to a worn-out belt that could snap if not addressed.

Action Steps:

• Turn Off the Unit: Prevent further damage by turning off your AC.
• Inspect for Visible Damage: Look for any visible signs of wear or damage.
• Contact a Professional: Reach out to HVAC experts like Roger Newman Heating & Cooling to diagnose and fix the problem.

2. Weak or Warm Airflow

If your AC is blowing weak or warm air, it’s failing to perform its primary function. This could result from issues like a failing compressor, low refrigerant levels, or blocked vents.

Anecdote: Last summer, my neighbor noticed warm air coming from her AC. After a quick check, we found the outdoor unit was covered in debris, restricting airflow.

Action Steps:

• Check Thermostat Settings: Ensure it’s set to “cool” and at the desired temperature.
• Inspect Vents and Filters: Clean or replace clogged filters.
• Seek Expert Help: Have a technician check for refrigerant leaks or compressor issues.

3. Frequent Cycling

An AC that frequently turns on and off, known as short cycling, often indicates underlying problems. This could be due to an oversized unit, thermostat issues, or refrigerant leaks.

Example: Consider your AC turning on for just a few minutes, then shutting off repeatedly. This not only wears out the system but also fails to cool your home efficiently.

Action Steps:

• Check Thermostat Placement: Ensure it’s not in direct sunlight or near heat sources.
• Inspect Air Filters: Replace if dirty, as they can cause the system to overheat.
• Consult HVAC Professionals: Get a thorough system evaluation to address short cycling.

4. Unpleasant Odors

Foul or musty smells coming from your AC can indicate mold growth, burned-out wire insulation, or even pest infestations within the unit.

Anecdote: A client once complained of a musty smell every time they turned on their AC. Upon inspection, we found mold growing on the evaporator coils.

Action Steps:

• Change Filters Regularly: To prevent mold and bacteria buildup.
• Schedule Regular Maintenance: Professional cleaning of coils and ducts.
• Use Deodorizers: Consider installing a UV light system to kill bacteria and mold.

5. High Humidity Levels

Your AC should reduce humidity levels indoors. If you notice sticky or damp air, it’s a sign your AC isn’t working correctly.

Example: One hot July, I noticed my home felt more humid than usual despite the AC running. It turned out the evaporator coil was clogged, preventing proper dehumidification.

Action Steps:

• Check for Clogs: Ensure condensate drains and pans are clear.
• Inspect System Size: An undersized unit may struggle to dehumidify properly.
• Call in Experts: Have a professional evaluate and possibly recalibrate your system.

Key Questions to Ask Your HVAC Expert

When seeking professional help, it’s crucial to ask the right questions to ensure you receive quality service:

• What is causing the issue, and what are the repair options?
• How long will the repair take, and what are the costs involved?
• Are there any preventative measures to avoid future problems?
• Do you offer maintenance plans or service agreements?
