Frequently Asked Questions

We recommend having your air conditioner serviced at least once a year. It is ideal to have it checked in the spring before the cooling season begins. Regular maintenance helps your system operate efficiently. It can also prevent unexpected breakdowns.

First, check the thermostat settings. It should be set to “cool” and the temperature should be correctly set. Next, check the circuit breaker to see if it has tripped. Lastly, inspect the air filter to ensure it’s not dirty or clogged. If these steps don’t resolve the issue, turn off the unit. Contact our professional technicians at Groulx Mechanical Heating & Cooling for prompt and reliable service. Avoid attempting any repairs yourself. This could cause further damage or void your warranty.

Signs you need a repair include inadequate cooling, unusual noises, and strange odors. Frequent cycling on and off and higher-than-normal energy bills are also indicators. If your system is leaking water or refrigerant, it’s time to schedule a service appointment. Likewise,  if you experience uneven cooling in different areas of your home, you should also schedule an appointment. 

Regular maintenance improves the efficiency of your cooling system. Keep the air filters clean, seal any leaks in the ductwork, and use a programmable thermostat. Ensure your home has proper insulation. Lastly, avoid blocking vents to maintain adequate airflow around your unit.

Our maintenance services include a comprehensive inspection of the following:

  • Cooling System
  • Cleaning Essential Components
  • Checking Refrigerant Levels
  • Tightening Electrical Connections
  • Lubricating Moving Parts,
  • Ensuring the system operates efficiently. 

We also provide recommendations for any necessary repairs or improvements.

You should replace your furnace filters every 1-3 months. However, it still depends on the type of filter and the conditions in your home. Homes with pets, smokers, or allergy sufferers may require more frequent filter changes to maintain good indoor air quality and system efficiency.

A typical air conditioner installation usually takes one full day. However, it depends on the complexity of the installation and the specific requirements of your home. Our team works efficiently to ensure minimal disruption to your routine.
