Understanding The Causes and Solutions For HVAC Emergencies

There are many reasons the heating, cooling, ventilation, and air conditioning systems of Charlotte homeowners fail. 

This article describes common HVAC emergencies, both causes and solutions. 

Four Common HVAC Emergencies In Charlotte

Residential heating and cooling systems fail for a variety of reasons. 

Here are the four most common causes of HVAC failure in Charlotte, North Carolina.

  1. Leaks
  2. Lack of maintenance
  3. Poor installation
  4. Component failure

Leaks within a heating and cooling system are the main cause of HVAC emergencies, but it isn’t the only reason. 

While the issues listed above are the four most common problems associated with home comfort system failure, there are solutions to each and every one of them.

Refrigerant Leaks Can Lead To System Malfunction


Refrigerant leaks often are a result of small holes in refrigerant lines or cracks in the coils.

As pressure increases, the coolant begins to leak.

These leaks can be recognized by a hissing sound, high energy bills, or low airflow.

Long cooling cycles, loss of cold air, or odd smells may also be an indication of a refrigerant leak.

Leaks can be caused by a number of things.

Damage to the A/C unit, normal wear and tear, or even mild vibrations can cause holes in the line to appear.

How does one resolve a refrigerant leak?

The only solution to a refrigerant leak is to call in the help of a certified HVAC technician.

Refrigerant leaks are hazardous chemicals that need to be handled by trained professionals.

A qualified technician can find the leak and repair it.

Lack of Maintenance 

A lack of maintenance is the second leading cause of HVAC failures.

Charlotte homeowners who invest in regular maintenance have fewer problems than those who don’t.

Over time dust, dirt, and other debris can build up in the system causing it to break down. 

Without proper maintenance, certain system elements are affected.

Coils, air filters, and even compressor fans can become dirty and damaged.

When this happens the system cannot function properly.

Charlotte residents can take matters into their own hands by ensuring the area around the HVAC unit is kept clean and free of dust and grime and by changing air filters regularly.

A certified service technician can perform routine maintenance and cleaning to maximize system performance. 

Poor Installation

HVAC systems that are installed poorly are almost guaranteed to fail.

There are multiple electrical and mechanical elements that need to be connected and installed properly.

Should a system fail as a result of faulty installation, a licensed technician can fix the issue.

The certified technicians at My Air Today are Charlotte’s number-one choice for HVAC installation.

Component Failure 

A heating, cooling, ventilation, and air conditioning system has many components.

Compressors are often the victim of regular wear and tear, as are the fan controls.

With excessive use, these components can corrode and wires can become worn.

This issue is common when systems are too large or are constantly turned on and off.

The solution to component failure is simple.

HVAC technicians who are insured, licensed, and bonded can diagnose and repair the issues they find. They are also knowledgeable to determine if the system needs a simple repair or an entire replacement.
