Common Reasons for an Under-Performing AC Unit

Is your air conditioning system struggling to beat Chicagoland’s sweltering summer heat? Have you noticed your home simply isn’t as comfortable as it used to be? If so, identifying and correcting the issue can improve your comfort and potentially put money back in your wallet. Here are a few key factors to consider when it comes to your under-performing AC system.

Poor Installation

Common mistakes during AC replacement or installation can cause even the most effective and efficient HVAC systems to underperform. In fact, improper installation can cause your cooling system to consume up to 30 percent more energy than necessary. This wastefulness means higher utility costs and less effective cooling when you need it most. Among the most common installation problems are leaky ducts, improper refrigerant charge and inadequate, restricted airflow.

Inadequate Maintenance

The simple fact is that poor maintenance is responsible for more underperforming and failing air conditioners than anything else. Every system experiences normal wear and tear, but the problems are only exacerbated without regular servicing. Clogged filters cause your system to work harder for lesser performance. Dirty or poorly adjusted blower components disrupt airflow and may decrease performance by up to 15 percent. Scheduled maintenance can alleviate these issues and ensure your system is always in optimal condition. As a bonus, it’ll also help you avoid costly AC repairs.

Improper Sizing

If your air conditioner is still under-performing despite being well-maintained, it’s likely your system is incorrectly sized for your needs. For best results, the capacity of your AC system should match the typical cooling needs of your home. A system that’s too small will often run constantly and struggle to achieve a comfortable temperature. Too large a system often causes short-cycling, excessive humidity and unpleasant temperature fluctuations. In either case, an AC replacement may be the best option for achieving more affordable and consistent cooling.

If your AC system just isn’t up to the task, it’s time to act before the problem becomes even worse. For more ways to maximize your air conditioning performance, check out Assurance Heating & Air Conditioning’s AC repairs and maintenance services or call 847-388-0316 today.
