​Is your HVAC system up to the task?

Air Duct Repair & Replacement Services

An entirely new HVAC system can be costly. There are times when it will be necessary to replace your system, but here at Smoak’s, we believe in forging long-term relationships with our customers. Therefore, we take all care to determine if we can make less-expensive repairs first rather than replacing an entire system.

​When we come to your house to perform a diagnostic of your HVAC system, we run through a standard series of tests, including:

  • Installing or troubleshooting the system
  • Inspecting easily accessible ducts for obvious air leaks
  • Inspecting the flue and venting locations
  • Checking the temperature across the system for proper fan speed
  • Checking airflow across the system
  • Checking CO2 at venting endpoints
  • Finding the source of the issue
  • Determining whether the system has enough life left to repair; if the system is old, it will probably need to be updated.
  • Ensuring your current or replacement system is the right size for your home or business.
  • If replacing, discussing the installation of an energy-efficient system, as this will result in lower energy bills over time and longer system life
  • Establish a routine preventative maintenance plan on your HVAC system to keep your system running smoothly for as long as possible.​

Several factors will invariably lead to new HVAC duct installation, such as an old system, a poor design, low-quality materials, or mold build-up.

Age of the System

A system installed correctly and with high-quality materials has a useful life expectancy of 8-12 years. Depending on your system’s age, replacing it might be more cost-effective than repairing it.


Mold in your home is serious; it can cause various illnesses, including respiratory, confusion, and general malaise. If your ducts are made of plastic and have mold, replacing them is a good idea.

Poor-Quality Materials or Design

​If the system in your house was built or remodeled using cheap materials, or if it is just a poor design, replacing those materials with high-quality ones will dramatically affect how efficiently your system operates. A substandard design may be salvageable with some specific repairs, but a replacement is probably the best solution if its design is inferior.

Why it is Important to Have Well-Sealed Ductwork

A well-functioning HVAC (Heating, Ventilation, and Air Conditioning) system is essential for making your residential or commercial property comfortable through the chilly South Carolina winters and hot Charleston summers. If you have leaky ductwork, no matter how energy efficient your unit is, it will not work correctly.

Leaky ducts are a significant reason behind inefficient systems, resulting in poor air distribution and high energy costs due to improperly sealed systems. Up to 40% of cooled air can be lost in your attic. If your ducts have cracks, holes, or gaps, bacteria, mold, and other harmful pathogens can enter your home or business.

An HVAC system constantly turning on and off as it tries to regulate your home’s temperature can put a great deal of wear and tear on the system, necessitating early repairs or even replacement.

How Do I Know if My Air Ducts are Leaking?

Several things will easily tell you if your ductwork is leaking. First, you might feel certain rooms in your home or business are rarely at the right temperature. You can put your hand or a tissue against a register and see if there is any airflow.

Too-cold or too-hot rooms might have little or no air coming through the registers. You might even notice there is always dust around your registers. And perhaps most apparent of all, your property’s heating and cooling bills are more expensive than usual.

Our team of experts at Smoak’s Comfort Control can help. Properly sealed and insulated ductwork will solve these inefficiencies while increasing the airflow within your home or business and improving air quality. It can also reduce safety hazards due to backdrafting, which is when combustion gases get released into the house instead of being vented to the outside.

The next thing to do is determine whether you should repair or replace your ductwork.
