Is your air conditioner no longer cooling?

An air conditioner that no longer cools can be caused by clogged filters, a dirty coil, insufficient airflow, or a thermostat issue. In some cases, the cause may also come from an electronic board, a fan, a refrigerant leak, or a faulty component in the outdoor unit. AirGreen provides a clear diagnosis to identify the true source of the problem.

Find the fresh air

Is your air conditioner leaking?

A water leak can quickly cause damage in a condo, plex, house, or business in Montreal. The most common causes are a clogged drain, a poor slope, a defective condensation pump, or a dirty indoor unit. Sometimes, the installation also needs to be corrected to ensure proper water drainage.

Protect my home

Is your air conditioner making noise?

An unusual noise can come from a dirty turbine, vibration, a loosely fixed external support, a , or a worn bearing. Debris in the outdoor unit or the presence of ice can also cause abnormal sounds. AirGreen checks the source of the noise to prevent the problem from worsening.

Find the silence

Is your air conditioner freezing?

An air conditioner that freezes often indicates lack of airflow, a dirty coil, a clogged filter, insufficient refrigerant level, or a ventilation problem. Continuing to use a frozen unit can make the situation worse. AirGreen can inspect the system and offer you the most logical solution.
