Your HVAC (Heating, Ventilation, and Air Conditioning) system is the lifeline of comfort in your home, especially during scorching summer days.

However, like any complex system, HVAC units can encounter common problems during the summer months. From uneven cooling to frozen coils and thermostat malfunctions, these issues can disrupt your indoor comfort.

That’s where a professional HVAC contractor like Majano Heating and A/C comes in. With our expertise and experience, we can efficiently diagnose and fix common HVAC problems in summer, ensuring that your home stays cool and comfortable throughout the summer season.

Let’s discuss the five most common HVAC problems in summer and provide practical solutions to help you keep your system running smoothly throughout the hot months.

1. Air Conditioner Not Cooling Properly:

One of the most common HVAC problems in summer is when your air conditioner fails to cool your home adequately. This could be due to clogged air filters, refrigerant leaks, or a malfunctioning thermostat.

Start by checking and replacing your air filters regularly and ensure that vents are not blocked by furniture or curtains. If the problem persists, it’s best to consult a professional HVAC technician to diagnose and repair AC.

2. Uneven Cooling Across Rooms:

Another common HVAC problem is uneven cooling, where some rooms in your home feel warmer than others. This could be caused by ductwork issues, improper insulation, or a malfunctioning blower motor.

Professionals check for leaks or blockages in your ducts and seal any gaps to improve airflow. Adding insulation to attics or crawl spaces to help maintain consistent temperatures throughout your home.

3. Frozen Evaporator Coils:

If you notice ice buildup on your air conditioner’s evaporator coils, it indicates a problem with airflow or refrigerant levels.

Turn off your AC system and let the ice melt completely before inspecting for clogged filters or blocked vents. If the issue persists, it’s essential to have a professional HVAC contractor check and adjust refrigerant levels to prevent further damage to the system.

4. Thermostat Issues:

A malfunctioning thermostat can lead to inaccurate temperature readings or erratic cooling cycles. Professionals check the batteries in your thermostat and ensure it is set to the correct mode (cooling mode for summer).

If the problem continues, consider upgrading to a programmable thermostat for more precise temperature control and energy savings.

5. Loud or Unusual Noises:

Unusual noises such as grinding, banging, or rattling coming from your HVAC system indicate potential mechanical issues. These noises could be due to loose components, worn-out belts, or failing motors.

It’s crucial to address these issues promptly by scheduling a professional HVAC inspection and repair to prevent further damage and ensure efficient operation.
