As an HVAC contractor at Perry Aire Services, Inc, located in Arlington, VA, I’ve witnessed firsthand the critical importance of recognizing common signs indicating that your AC system requires professional repair. It’s tempting to try DIY solutions, but hiring a reputable HVAC contractor like Perry Aire Services, Inc is crucial to ensure the efficiency and longevity of your cooling system. In this blog post, I will outline some key indicators that should prompt you to seek professional AC repair services.

1. Insufficient Cooling

If you notice that your air conditioner isn’t cooling your home as effectively as it used to, it’s a clear sign of a problem. While it may be tempting to tweak settings or adjust vents, it’s important to resist the urge to fix it yourself. In such cases, contacting a professional HVAC contractor is essential. They possess the expertise to identify and resolve the underlying issue, whether it’s a faulty compressor, refrigerant leak, or another component malfunction.

According to renowned industry sources, such as the Air Conditioning Contractors of America (ACCA) and the U.S. Department of Energy, inadequate cooling can result from various factors, including improper installation, refrigerant problems, or clogged air filters. Entrusting the repair to an experienced professional will ensure accurate diagnosis and proper solutions.

2. Unusual Noises or Odors

Another telltale sign of AC system problems is the presence of strange noises or unpleasant odors emanating from the unit. Unusual rattling, buzzing, grinding, or squealing sounds may indicate worn-out parts, loose connections, or debris accumulation. Likewise, foul odors can be a sign of mold growth, burnt wires, or even pest infestation within the system.

Recognizing the importance of addressing these issues promptly, industry-leading organizations like the Heating, Refrigeration, and Air Conditioning Institute of Canada (HRAI) strongly advise seeking professional assistance. HVAC contractors have the necessary authority and knowledge to tackle such issues safely and effectively. At Perry Aire Services, Inc, we prioritize thorough inspections and utilize cutting-edge diagnostic techniques to identify the root cause of any disturbing noises or odors.

3. Frequent Cycling or High Energy Bills

Does your AC system seem to cycle on and off more frequently than usual? Excessive cycling can strain the components and lead to premature wear and tear. Additionally, if you’ve noticed a sudden spike in your energy bills without any significant change in usage, it’s indicative of an inefficient system that requires professional attention.

Reputed sources like the Energy Star program and the U.S. Environmental Protection Agency (EPA) assert that irregular cycling and high energy consumption are common signs of AC system problems. Attempting to fix these issues without the necessary expertise may result in further damage or even void your warranty. By hiring a professional HVAC contractor like Perry Aire Services, Inc, you can ensure that your system is thoroughly evaluated, optimized, and restored to its peak performance, leading to energy savings and reduced operating costs.

4. Poor Air Quality and Airflow

If you’ve noticed a decline in the air quality within your home, such as excessive dust, musty smells, or uneven airflow, it’s crucial to address these concerns promptly. Poor indoor air quality can lead to health issues, while compromised airflow can cause hot and cold spots, making certain areas uncomfortable.

Respected organizations such as the American Lung Association and the Environmental Protection Agency emphasize the importance of maintaining good indoor air quality. A professional HVAC contractor possesses the necessary knowledge and tools to assess your system comprehensively. By conducting thorough inspections, cleaning ducts, and identifying and eliminating pollutants, they can significantly improve your home’s air quality and ensure proper airflow throughout.


Recognizing the importance of promptly addressing AC system issues is essential for maintaining a comfortable and healthy living environment. While it may be tempting to tackle repairs yourself, entrusting the task to a professional HVAC contractor like Perry Aire Services, Inc in Arlington, VA, is the wisest choice. By doing so, you can rest assured that your AC system will be in the hands of experts who will efficiently diagnose, repair, and optimize its performance, ensuring long-term functionality and peace of mind.
