There may be several reasons why your AC is not cooling evenly, and it's important to know when to call a professional HVAC contractor. Here are some of the common reasons why your AC may not be cooling properly and when it's time to hire a residential HVAC contractor.

Clogged Filter

One of the most common reasons is a clogged filter. A dirty and clogged filter can block the airflow, making it hard for the AC to circulate the cool air properly. It's best to change the filter regularly to avoid this problem, and if you notice dirty air filters, it's time to clean or replace them.

Dirty Coils

Over time, the coils inside the AC unit can accumulate dirt and debris, which can also block the airflow and decrease the effectiveness of the cooling system. This can cause uneven cooling and higher energy bills. In this case, it's important to have a professional clean the coils as part of regular maintenance.

Leaky Ducts

Leaky ducts can also lead to uneven cooling, as the cool air escapes through the holes and cracks. This can also cause higher energy bills, as the AC unit has to work harder to compensate for the loss. A professional HVAC contractor can diagnose and repair any leaks in the ducts, ensuring efficient cooling.

Incorrect AC Sizing

If your AC unit is too small or too big for your home or office space, it may not be able to cool evenly. An experienced HVAC contractor has the expertise to evaluate your cooling requirements and suggest the ideal size and kind of air conditioning unit that will deliver efficient and uniform cooling.

Blocked Condenser

The outdoor unit of the AC system called the condenser, can also get blocked with debris like leaves, grass, and dirt. This can restrict the airflow and decrease the efficiency and cooling capacity of the unit. A professional HVAC contractor can clean and clear any debris, ensuring the proper function of the condenser.

Uneven cooling is a common problem with air conditioning systems and can be caused by several reasons, like a clogged filter, dirty coils, leaky ducts, incorrect sizing, or a blocked condenser. While some of these issues can be resolved by simple maintenance tasks, some require the expertise of a professional HVAC contractor. Regular maintenance and timely repairs can ensure efficient and even cooling and prevent costly repairs and replacements in the future. If you notice any uneven cooling or suspect any issue with your AC unit, it's best to contact a reliable HVAC contractor to diagnose and fix the problem.
