Stay Cool with Quality AC Services 

In Stockton, air conditioning is crucial to comfort and air quality. Depending on the nature of the problem with an air conditioning system, it may require repair or replacement. Generally, an air conditioning unit that is not very old can be repaired. However, an old unit that needs a large and expensive repair may need to be replaced. This is especially true if you have repaired the system in the past and it isn’t working again. 

When it is time for new equipment, there are many options for energy-efficient, high-quality units to provide the comfort you need at a price that will fit your budget. Choosing the right size system and hiring a professional for the installation will ensure optimal performance and energy efficiency. 

Your new air conditioning system is a big investment. Of course, you want it to perform at peak efficiency throughout its entire lifespan. The best way to accomplish this is with regular professional AC maintenance. Staying current with air conditioning maintenance improves performance, energy efficiency, lowers home cooling costs, and extends the life of your system. 

Professional AC maintenance includes:

  • Check and change air filters – HVAC technicians check and change air filters during regular maintenance visits. In between visits, you should change the filter every one to three months, depending on use. 
  • Thorough cleaning – Dirt, dust, and other debris can create obstructions that decrease efficiency. Maintenance visits include cleaning the components of the system to improve performance and air quality. 
  • Clear away obstructions or debris – The area around the outdoor unit should be clear to allow for optimal airflow. Plants and other yard debris need to be cleared away from the unit. 
  • Check components – During maintenance visits, the technician will check the refrigerant level and mechanical components of the system to ensure that everything is working as it should. 

Another benefit of professional maintenance service is detecting small problems early. Your HVAC technician can alert you to any potential issues that are found during routine inspections and tune-ups. This enables you to fix any minor problems before they grow bigger and more expensive.
