The Musty Smell From HVAC: How To Solve It

HVAC Musty Smell

Customers are turning away from this musty smell

Customers are more likely to leave if they smell bad food, mold, mildew, or in the restrooms. Your business could be in serious trouble if you have persistent odors in your retail store, restaurant, or health club.

Psychologists who study the effects of odors on people have found that they quickly become accustomed to them. Your employees may not notice an odor as quickly as you do, but customers will notice it as soon as they enter the room. They will walk out of the door in a hurry.

Is there an odor coming from your HVAC system

It can be difficult to fix odor problems, as the causes may not always be obvious. You’ve likely already tried cleaning products and deodorizers to get rid of an unpleasant smell.

These remedies may not be enough to stop the spread of odors in your space. There are two things that can lead to unpleasant odors in your home:

  • Unmaintained HVAC equipment which retains moisture and emits a musty odor.
  • A poorly designed HVAC airflow could push air in an unfavorable direction, causing unpleasant odors to be spread to the areas your customers are using (e.g. the bathroom to the dining room).

You can eliminate musty odors from your space by proper inspection and maintenance

You should call an expert to inspect your HVAC system if you notice an odor. Inadequate maintenance of exhaust systems blocked vents or filters, and clogged drain lines may lead to water leaks that can cause a buildup of moisture and grime, which can then create a musty smell.

These issues can be addressed by regular maintenance so that odors don’t plague your space or drive customers away.

You will lose business every day you sit and wait for deodorizers or scented candles to work. Yelp reviews will show that customers are complaining about the unpleasant smell at your restaurant.

Airflow is the key to controlling odors

HVAC systems circulate air throughout buildings. Air is removed from spaces by exhaust fans, clothes dryers, and built-in vacuums. Air conditioners, heating systems, and ventilation systems may supply air or push air into a space. Negative airflow occurs when there is more air being removed from an area than there is air being supplied.

Positive airflow is produced when there is more air being pushed into your space than is removed by the exhaust. A positive airflow is generally good for comfort. However, there are situations where a negative flow of air is necessary.

This is why it is so important for your business. Because air movement can also move odors. A properly designed HVAC airflow can use air pressure conditions to move odors away from customers.

HVAC professionals can accomplish this by making sure that the air that is being exhausted from the problem (or smelly) zone is more than the replacement (also known as makeup air). This is a great way to get rid of bad odors or musty stenches that could be affecting your business.

Here are some examples of HVAC design that eliminates odors

  • Commercial Kitchen: Ventilation systems should be designed so that there is negative pressure in the kitchen. This will prevent strong odors from lingering. The conditioned air is drawn from the dining area toward the kitchen. This prevents odors from moving from the kitchen to the dining area, where customers are eating.
  • Restrooms: It needs negative airflow to allow clean air to flow in and for smelly air to be drawn out by an exhaust fan. Those offensive odors can spread to other areas, where they could be offensive to your customers.
  • Water treatment: facilities, as well as chemical plants, can create odor problems on a larger scale and require specialized odor control devices. These devices might not work if the ventilation system of the facility uses negative airflow to stop odors escaping before they can be captured by the odor control device.

Certified professionals like AC company Fort worth will inspect and evaluate all heating, cooling, ventilation equipment. An inspection might reveal that certain design changes are necessary to ensure air flows in the right direction. You will need to hire a contractor who has the experience and skills to create an effective solution.

There are many reasons HVAC airflow should be controlled

You can also control odors by preventing air from flowing between different areas in your building. Negative air pressure can be used to prevent the spread of odors and other contaminants.

  • Kitchens must be designed to ensure worker safety and health, as well as odor control. The kitchen should have negative airflow to reduce the hazards of smoke and fire and remove any air pollutants from cooking appliances that could cause breathing problems for your employees.
  • Hospitals Keep people with communicable diseases in isolation rooms under negative pressure. The negative pressure prevents airborne bacteria and viruses from entering the room. Only filtration systems that capture contaminants draw air out of the room.
  • Manufacturing facilities that work with hazardous materials must create areas of negative airflow to protect workers from chemical fumes.
  • Health clubsMoldy locker rooms in health clubs can not only make customers sick but also cause them to lose business. A healthy airflow system in a gym moves air from the fitness area toward the dry portion of the locker rooms, then towards the wet shower area where it is eventually expelled by a powerful exhaust. This design prevents unpleasant odors and dangerous mold growth.
