How Much Does Air Duct Cleaning Cost?

HVAC stands for Heating, Ventilation, and Air Conditioning. It is a system that controls the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.

There are several different types of commercial HVAC systems available in the market. They all work on the same basic principle: the system has a source of heat, a source for cool air, and a way to distribute the air throughout the space by fans and ducts.

HVAC systems include various components such as the furnace (for heating), air conditioner or heat pump (for cooling), ventilation system (which includes the air ducts), and thermostat for temperature control. The HVAC system is responsible for regulating indoor air quality, temperature, and humidity.

But sometimes problems occur that if left unaddressed leads to costly HVAC system repairs that can also increase air duct cleaning cost. Here we will look at common signs of duct cleaning in wilmington that must be addressed to ensure a comfortable office environment.

Signs your HVAC System Needs Repair

Preventative maintenance is important if you want to reduce air duct cleaning cost. Several tell-tale signs may indicate that your commercial HVAC system needs repairs. Read below to know them so you can act accordingly.

1. Strange Noise or Smell

Unusual noises or odors coming from the system, such as squealing or clanking sounds, or strange smells of burnt rubber or electrical faults.

There are many reasons why your HVAC system might be making unusual noises. Some of the most common causes include:

  • Loose or damaged parts. Over time, the parts in your HVAC system can wear down and become loose or damaged. This can cause them to rub against each other, making noise.
  • Blocked ducts. Blocked ducts can also restrict airflow, causing noise.
  • Low refrigerant levels. If the refrigerant levels in your HVAC system are low, it can cause the system to work harder, which can lead to noise.


Unusual noises from your HVAC system may be a sign of a more serious mechanical problem. If you notice any unusual noises, it’s best to have your HVAC system inspected by a qualified technician at Facilities USA as soon as possible.

2. Decreased HVAC Performance

Decreased performance, such as reduced temperature control, unusually high energy usage, or frequent system shutdowns. Some of the probable reasons for decreased HVAC performance include the following:

  • Dirty filters.Dirty filters can restrict airflow, making it harder for your HVAC system to heat or cool your home. It is recommended to change your air filter every 1-3 months, depending on the type of filter you have.
  • Blocked ducts. Blocked ducts can also restrict airflow, making it harder for your HVAC system to heat or cool your home. If you have any furniture or other objects blocking the ducts, move them out of the way.
  • Low refrigerant levels. Over time, the refrigerant levels in your HVAC system can decrease. This can cause your system to work harder, making it less efficient. If you think your refrigerant levels are low, you should have your HVAC system inspected by a qualified technician.
  • Old or damaged parts.Over time, the parts in your HVAC system can wear down and become damaged. This can cause your system to work less efficiently. If you think your HVAC system has old or damaged parts, you should have it inspected by a qualified technician.
  • Mechanical problems.In some cases, a reduced heating or cooling capacity may be a sign of a more serious mechanical problem with your HVAC system. If you notice a significant drop in performance, it’s best to have your HVAC system inspected by a qualified technician as soon as possible to reduce air duct cleaning costs.


If you notice that your HVAC system is not heating or cooling as well as it used to, it’s important to troubleshoot the problem as soon as possible. By identifying and fixing the problem, you can keep your HVAC system running efficiently and extend its lifespan.

3. Increased maintenance costs

Increased maintenance costs, such as frequent repairs or service calls to the system are another sign that your company’s HVAC system needs repairs.

Visible damage or wear to the system components, such as rust or corrosion on the system’s exterior or signs of leaking fluids.

You may also notice reduced air quality, such as the presence of mold or dust on the system’s air filters, which can affect the comfort and health of the occupants.

If you observe any of these signs, it’s important to contact a licensed HVAC specialist to diagnose and repair the problem. Neglecting to address these issues could result in higher energy costs, poor indoor air quality, and the risk of equipment failure, which could lead to significant downtime and costly repairs.

4. Water Seeping From the Unit:

An HVAC system leak may be indicated by water buildup around the unit. Leaks in air ducts can cause moisture problems, which can encourage the growth of mold and lower indoor air quality.

5. Notable Air Leaks:

Notable air leaks in the air ducts can cause a large loss of conditioned air, which lowers your HVAC system’s overall effectiveness. Drafts and hissing noises near the ducting are indicators that a leak may exist and has to be fixed. It is essential to quickly seal these leaks in order to preserve energy efficiency and guarantee adequate ventilation throughout your house.

How Much Does Air Duct Cleaning Cost?

The size of the HVAC system, the intricacy of the ductwork, the location, and the quality of service rendered are just a few of the variables that can significantly affect the air duct cleaning cost. The average cost of cleaning an air duct system might be anything from $300 to $1,000 or more. The following are significant parameters that affect the price:

  • Size Matters:

Larger HVAC systems with more ductwork will generally cost more to clean than smaller systems.

  • Accessibility of Ducts:

If the ducts are easily accessible, the cleaning process may be more straightforward and less expensive. In contrast, if the ducts are difficult to reach or require additional effort for cleaning, the cost may increase.

  • Extent of Contamination:

If the ducts are heavily contaminated with dust, debris, mold, or other pollutants, additional cleaning efforts may be required, impacting the overall cost.

  • Extra Services:

Some companies may offer additional services such as sanitizing, deodorizing, or applying antimicrobial treatments to the ducts, which can increase the overall cost.

  • Location and Regional Variations:

Prices for services, including air duct cleaning, can vary based on the cost of living and business expenses in different regions.

  • Company Reputation and Expertise:

Established and reputable companies may charge higher prices for their services, but they often provide more comprehensive and reliable results.

Don’t just go for the cheapest service since it may indicate poor quality or hidden expenses. It’s a good idea to get various quotations before picking a service provider, as well as inquire about the exact services provided and verify customer reviews and the company’s qualifications.

Also, remember that not everyone feels that regular cleaning of the air ducts is necessary. According to the Environmental Protection Agency (EPA), duct cleaning is not always required and should be evaluated on an individual basis, particularly in cases where there are specific issues like mold growth or an abundance of debris. A skilled HVAC technician can assist you assess whether air duct cleaning is necessary in your specific circumstance.
