Why Isn't My HVAC System Cooling? Troubleshooting Tips from AirClinic

Updated: Jun 15, 2023

Are you feeling the summer heat seeping into your home despite your HVAC system being turned on? It's frustrating when your cooling system fails to keep you comfortable, especially during scorching hot days. At AirClinic, your trusted HVAC service company in San Antonio, Hill Country, Dallas, and Fort Worth, we understand the importance of a well-functioning cooling system. In this blog post, we'll explore common reasons why your HVAC system may not be cooling effectively and provide troubleshooting tips to help you beat the heat.

1. Check Your Thermostat Settings:

Sometimes, the issue is as simple as incorrect thermostat settings. Ensure that your thermostat is set to "cool" mode and that the temperature is set lower than the current room temperature. If the thermostat uses batteries, replace them to rule out a power issue.

2. Inspect and Clean Air Filters:

Clogged air filters can restrict airflow and hinder cooling efficiency. Regularly inspect your air filters and clean or replace them if necessary. We recommend performing this maintenance task at least once a month to ensure optimal performance.

3. Clear Obstructions from Vents:

Obstructed supply and return vents can impede airflow, causing inadequate cooling. Check that furniture, curtains, or other items are not blocking the vents. Make sure all vents are open and unobstructed to allow cool air to circulate freely throughout your home.

4. Examine the Outdoor Unit:

Your HVAC system's outdoor unit plays a crucial role in cooling your home. Ensure that the unit is free from debris, such as leaves, grass, or dirt, that might obstruct the airflow. Trim any nearby vegetation to maintain adequate clearance around the unit. If you notice ice or frost buildup on the unit, it could indicate a refrigerant issue, and you should contact AirClinic for professional assistance.

5. Assess Ductwork for Leaks:

Leaky ductwork can lead to cooled air escaping before it reaches your living spaces. Inspect your ductwork for any visible leaks or loose connections. If you suspect a problem, our skilled technicians at AirClinic can perform a thorough inspection and provide duct sealing services for improved efficiency.

6. Verify the Condenser Unit:

The condenser unit is responsible for removing heat from the refrigerant. Ensure that it is clean and unobstructed. If you notice strange noises, such as rattling or grinding, coming from the unit, or if it fails to turn on, it's time to contact AirClinic for professional diagnosis and repair.

7. Schedule Regular Maintenance:

Preventive maintenance is key to ensuring your HVAC system operates efficiently and reliably. By scheduling regular maintenance with AirClinic, our experienced technicians can identify and address minor issues before they turn into major problems. Our comprehensive maintenance services will keep your system in top condition and extend its lifespan.
