HVAC airflow problems should be taken care of immediately once they are noticed. It means that you need to know how to identify them so you can call for HVAC system repairs in St-Laurent or in Montreal area services in good time. Though signs may vary depending on the exact nature of the problem, here are some of the indicators that you may be having HVAC airflow issues:

  • Hot and cold spots within the space
  • Pressure imbalance i.e. you notice drafty areas, strange whistling or doors slamming on their own
  • Little to no air coming from the air conditioning units
  • Warm air coming from the AC system

Ignoring such signs will be bad for your system and also for your pocket and this is why you should always take action as soon as possible. In most cases, these issues are easy to resolve, and you may not need to call for HVAC repair service in Montreal  once you know about them and you know what to do in each case. Here is a brief look at some of the specific causes of these problems and the recommended remedy:

Obstructed condenser unit

Obstructed condenser unit is one of the common HVAC airflow problems, and also an easy fix which will not require you to call for heating repairs in Dollard-Des-Ormeaux or in Montreal area. Air conditioning units usually have a condenser unit which is usually placed in a mechanical room or outside the room.

It is common for the outdoor units to get obstructed with leaves and debris that the unit may have accumulated over time. The units in the mechanical rooms may also face obstruction due to other equipment or items stored in the same room. All you need to do to deal with this problem is clear the area around the unit and also remove the dirt and debris from the outside units.

Clogged filters

The work of the filter is to prevent dust and debris from accessing the unit’s core components, and when they are clogged, airflow problems are bound to ensue. Over time, the dust and the debris do accumulate to prevent smooth flow of air through the vents.

As a result, hot and cold spots may be noticed inside the rooms, and there is also the possibility of the air being stuffy due to the dirt present in it. The filters ought to be checked on a regular basis, but it is sad to note that most people never check and clear the filters until they notice a problem. A simple solution is to simply change the filters as recommended by the manufacturer.

Leaky or blocked ducts

When the dust and debris go past the filters, they are likely to accumulate somewhere along the ductwork. Remember, the ducts are generally too narrow and as such, they can easily get clogged with dirt and debris. When that happens, airflow is likely to be interfered with.

Leaky ducts due to cracks and holes will also cause a lot of air to leak out of the system, giving rise to more airflow issues. The solution is to call for regular duct inspection so that all the ducts may be cleaned and all leaks can be sealed.

Dirty coils

The work of the coils in an AC system is to get rid of the heat obtained from the spaces. The coils are normally part of the outdoor unit, and as such, it is possible for dirt and debris to accumulate on them over time. When this happens, the efficiency of the coils will be affected, and this will ultimately lead to airflow issues. Always ensure that the coils are cleaned regularly to avoid this problem.
