Keeping Your HVAC System Free and Clear

After our heater stopped working altogether last winter, we realized that it might be time to consult with a professional. We called a family friend who is also an HVAC contractor and he came out right away to see what he could do. After taking a look at things, he told us that our vents were almost completely blocked with dust and dirt. He recommended a vent cleaning company to come out and help, and they removed loads of debris the next day with specialized suction tools. After that, our HVAC system ran almost perfectly. This blog is all about the importance of keeping your HVAC system free, clear, and functional.

How To Know If An Air Conditioner Unit Needs Repairing?

During the summer months, an air conditioning unit becomes essential for a comfortable living environment. However, like any mechanical device, air conditioners may encounter issues over time. This is why it is crucial to identify the signs that indicate a need for air conditioning unit repair. Thus, ensuring optimal performance and preventing potential breakdowns. As such, this article explores common indicators that suggest that an air conditioner requires attention. By understanding these signs, individuals can take timely action to maintain a cool and comfortable indoor atmosphere.

Insufficient Cooling

One primary indicator of an air conditioning unit in need of repair is a noticeable decrease in cooling performance. If the home doesn't cool as before, or if certain areas remain warmer than others, it may indicate a problem with the air conditioner. Possible issues include a faulty compressor, refrigerant leaks, or a malfunctioning thermostat.

Strange Noises

Unusual sounds coming from the air conditioning unit are often cause for concern. For instance, grinding, squealing, rattling, or banging noises may indicate loose or worn-out components. These sounds could result from belt issues, motor problems, or debris interfering with the fan blades. As such, a professional assessment is crucial to preventing further damage.

Frequent Cycling

Frequent on-off cycles, known as short cycling, can be a sign that the air conditioning unit needs repair. Short cycling may be caused by a malfunctioning thermostat, a clogged air filter, or an improper refrigerant charge. It not only compromises home comfort but also strains the system, leading to increased energy consumption and potential damage.

Leaks or moisture

The presence of leaks or moisture around the air conditioning unit should not be ignored. Refrigerant leaks not only impair cooling capacity but also pose health risks. This is because moisture buildup may indicate a blocked or damaged drain line. This means it can potentially cause water damage and mold growth. As it happens, mold that flows in breathable air can be hazardous to your health.

Unpleasant Odors

Foul odors emanating from the air conditioning system may indicate mold or bacterial growth within the unit or ductwork. These odors compromise air quality and may pose health hazards. Musty, moldy, or pungent smells when the air conditioner is running are a red flag. This will require urgent professional inspection and cleaning. 


There are many conditions that may affect the functioning of an air conditioning unit. Whether it is insufficient cooling or bad odors, all of the issues mentioned in this article require the intervention of a professional. As such, it's important for individuals to know when to call an expert to take care of the issue before it leads to further damage or health hazards.
