abc news

A well-functioning HVAC system is crucial for maintaining a comfortable indoor environment, especially during extreme weather conditions. However, there might be times when your HVAC system isn’t cooling or heating your home properly, leaving you feeling uncomfortable and frustrated. 

This blog post highlights the top reasons why your HVAC system might be underperforming and provides some useful tips to help you address these issues.

Clogged Air Filters

One of the most common reasons for an inefficient HVAC system is a clogged air filter. Air filters trap dust, pollen, and other airborne particles, preventing them from circulating throughout your home. Over time, these particles accumulate, reducing airflow and making it difficult for your HVAC system to heat or cool your home effectively. 

Check your air filters at least once a month and replace or clean them as needed. If this still doesn’t solve the problem, you should consider calling in a professional for HVAC services in Clarks Summit, PA.


Thermostat Issues

A malfunctioning thermostat could also be the reason behind your HVAC system’s poor performance. If the thermostat’s settings are incorrect or the device itself is faulty, your HVAC system may not receive accurate information, causing it to underperform. 

Ensure that your thermostat is set to the appropriate temperature and mode, and consider replacing it if it’s outdated or damaged.


Low Refrigerant Levels

Low refrigerant levels in your HVAC system can cause it to struggle with cooling your home. Refrigerant is the substance that absorbs heat from the air inside your home and releases it outside. 

If the refrigerant level is low, the system will have difficulty removing heat, resulting in inadequate cooling. Contact a professional HVAC technician to check for leaks and recharge the refrigerant in your system.


Dirty Condenser Coils

Located in the outdoor unit of your HVAC system, condenser coils play a crucial role in releasing heat from your home to the outside. 

Over time, dirt, leaves, and other debris can accumulate on the coils, reducing their efficiency and preventing your HVAC system from cooling your home effectively. Regularly inspect and clean your condenser coils to ensure they’re functioning optimally.


Obstructed Air Vents

Obstructed air vents can hinder the proper circulation of conditioned air in your home. Furniture, curtains, or other items placed too close to the vents may block airflow, causing your HVAC system to work harder than necessary to maintain your desired temperature.

To resolve this issue, make sure your air vents are clear of obstructions and allow for adequate airflow.


Ductwork Leaks

Leaky ducts can be a major cause of inefficiency in your HVAC system. Cracks or gaps in the ductwork allow conditioned air to escape before reaching its intended destination, resulting in uneven temperatures and increased energy consumption. 

Inspect your ductwork for any signs of damage and have it repaired or replaced as needed.


Inadequate Insulation

Poor insulation can also contribute to your HVAC system’s inability to maintain comfortable indoor temperatures. 

If your home isn’t well-insulated, heated or cooled air can escape easily, causing your HVAC system to work harder to compensate. Assess the insulation in your home and consider upgrading or adding more insulation to improve your HVAC system’s performance.


Aging HVAC System

An older HVAC system may simply be less efficient due to natural wear and tear. As your system ages, its components may begin to degrade, resulting in reduced performance. 

If your HVAC system is more than 10-15 years old, it may be time to consider upgrading to a newer, more energy-efficient model.



There are numerous reasons why your HVAC system may not be cooling or heating your home properly. Identifying the root cause of the problem is essential for finding the right solution. By regularly inspecting, cleaning, and maintaining your HVAC system, you can improve its performance and ensure a comfortable indoor environment all year round. If you’re unsure about the cause of your HVAC system’s issues or need assistance with repairs, don’t hesitate to reach out to a professional HVAC technician.
