Air Balancing

Air balance is one aspect of your HVAC system that determines whether or not the unit is working at its peak efficiency. A building that has been balanced has equal airflow and conditioning in every room, ensuring that the temperature throughout is consistent. To balance a building, our technicians will test the ducts and airflow to create a baseline and then make small adjustments before retesting. This goes on until the airflow has been balanced.


Economizers are devices that make your HVAC system more efficient. They help save energy costs by using air from outside to cool indoor air, gauging when the outside air temperature and humidity are cooler than the inside air.

Economizers can provide the following benefits:

  • Savings on your energy bill
  • Reduced carbon footprint
  • Improved indoor air quality

Our expert technicians will happily review your circumstances to determine if an economizer is right for your building.

AC Filters

If you are noticing increased allergy symptoms in your home or rising energy bills, it may be time to replace your AC air filter. An air filter is designed to trap dust, allergens, and other debris before it enters your air conditioning system. A new filter will not only improve the air quality in your building, but will prevent unexpected breakdowns within your system and improve the unit’s efficiency. Our All Pro Plumbing, Heating, Air & Electrical technicians can determine whether you need a new air filter, and will handle the installation, all at a great price with friendly service.

System Performance Testing

There are several performance tests that help our San Bernardino County cooling service technicians improve the efficiency and comfort levels of your HVAC systems.

Some of these tests include:

  • Airflow Testing: This test ensures that airflow is moving efficiently throughout your home and there are no blockages or disruptions in the system.
  • Energy Efficiency Testing: Using special calculations, we are able to determine if your cooling system is working efficiently. The goal is to produce the highest amount of energy at the lowest cost for you.
  • Indoor Air Quality Testing: If the air quality in your building is not optimal, you will experience increased allergy symptoms and other adverse effects. We run tests to make sure that your indoor air quality is the best it can be.
