Air conditioner repair Montreal’s North Shore

What are the signs that my wall or central air conditioner needs to be repaired?

If you think your air conditioner is not working as well as it should, don’t delay. A small problem that isn’t fixed quickly can lead to more costly repairs and possibly even the complete replacement of your air conditioning system.

  • Air comes out hot: If your evaporator or vents are blowing hot air, check your thermostat first. Make sure it’s on cooling mode and set it lower than the current temperature of your home.  If your vents and evaporator are still blowing hot air, a compressor problem or restricted airflow may be the problem.
  • Reduced or insufficient airflow: Poor airflow can also be a sign that your air conditioner isn’t operating at peak performance and that a blockage is preventing air from flowing properly. It could be a clogged filter, a motor problem, or another problem that needs to be evaluated by an air conditioning professional.
  • Frequent cycling: Your air conditioner needs to be cycled regularly, regardless of the weather. While your cooling system may come on more frequently on warmer days, it should not turn on and off quickly and constantly. If you notice more frequent cycling, contact a professional right away. A simple tune-up may solve the problem.
  • High humidity: Normally, your air conditioner should regulate the humidity level automatically. During the summer, your humidity level should not exceed 55%. If your air conditioner is struggling to maintain an acceptable humidity level, you may want to call in a professional to find the problem.
  • Your air conditioner is leaking: Your air conditioner uses refrigerant (Freon) to cool your home, which can produce condensation when your air conditioner is running. However, water should not collect or seep into your home. If water is pooling or dripping on your floor, it is a sign that your cooling system is not working properly. This is a problem that should not be overlooked; a refrigerant leak can cause major damage to your air conditioner.
  • Bad odors: If you have bad odors coming from your air conditioning system, you need to fix the problem right away. By inspecting your air conditioner, a technician will be able to see the problem. UV germicidal lamps work wonders to eliminate the growth of mold and microbes (often responsible for bad odors). A good cleaning of the ducts and your indoor and outdoor units can also solve your odor problem.
  • Unusual noises: Most air conditioner models make little noise when they start up or operate. However, loud noises such as grinding, popping or buzzing can indicate a problem, such as a loose or defective part. This type of problem rarely goes away on its own; an air conditioning professional will be able to figure out what the problem is.
  • Your electric bill is higher than usual: Notice an increase in your energy bill even though you haven’t changed your cooling habits? This could mean that your air conditioner has to compensate and work harder to do its job properly. This usually means that your air conditioner is broken.
  • Frost forms on the outdoor unit: If you notice frost and ice on your ducts and outdoor unit, it’s likely that your refrigerant is leaking. Only a professional refrigeration technician will be able to find the leak, seal it, repair it and recharge the fluid according to the manufacturer’s recommendations.
