Your System May Need Maintenance If You Notice These Signs

An air conditioning system or heat pump can continue operating even when it is losing efficiency. However, certain signs indicate that maintenance is recommended to help prevent a breakdown, excessive energy consumption, or premature wear.


J&J Climatisation can help if you notice any of the following signs:

  • your air conditioning cools less than before
  • your heat pump heats or cools less efficiently
  • the system runs longer to reach the desired temperature
  • airflow is weak or irregular
  • the unit is louder than usual
  • a bad odour comes from the unit or ducts
  • energy consumption increases without a clear explanation
  • some rooms are warmer or colder than others
  • filters get dirty quickly
  • the system has not been inspected for several seasons


These symptoms may result from poor maintenance, dirty filters, restricted airflow, and dust accumulation. Professional maintenance checks system condition and resolves issues early.

Our Air Conditioning and Heat Pump Maintenance Process

Proper maintenance relies on a structured approach. J&J Climatisation starts by discussing the type of system involved, the symptoms you have noticed, and how often it is used, whether it is central air conditioning, a heat pump, or an HVAC system.


Our team then checks the visible components and signs of performance loss, including filters, airflow, units, ducts, unusual noises, odours, or the general condition of the equipment.


Based on the situation, we perform the appropriate maintenance checks or interventions and clearly explain any recommendations if a potential issue is observed.


Once maintenance is complete, we verify the system’s general operation to make sure it better meets the building’s needs and helps improve comfort, reliability, and performance.

Frequently Asked Questions

Got questions about Air Conditioning and Heat Pump Maintenance in Laval?

We’ve got answers! Check out our FAQ section to learn more about heating, ventilation, and air conditioning.

  • How often should an air conditioning system be maintained?

    The frequency depends on the type of system, its age, how it is used, and the building environment. In general, regular maintenance helps maintain better performance and reduce the risk of breakdowns.


  • When should a heat pump be maintained?

    It is recommended to have a heat pump inspected before periods of heavy use, especially before summer or before winter, depending on how it is used. Maintenance may also be needed if performance decreases.


  • Why does my air conditioning smell bad?

    A bad odour may be caused by humidity, dust, dirty filters, or buildup in certain parts of the system. Maintenance helps identify the source of the problem.


  • Can maintenance reduce energy consumption?

    Yes, in many cases. A clean, properly inspected, and well-adjusted system can operate more efficiently than a dirty or neglected system.
