Air Conditioning

Why do I need to add refrigerant to my system?

You should not need to regularly add refrigerant to your system. Air conditioning systems do not use up refrigerant like a car uses gas. If your system is low on refrigerant it means that it has leaked out or was not charged correctly to begin with.

Air Conditioning

What type of filters should I use?

Premium pleated filters can do a good job filtering small particles, but can reduce airflow and make your system inefficient. This is called pressure drop. Cheap fiberglass filters have less pressure drop but can let smaller particles through. We sell a middle of the road pleated filter and washable electrostatic filters, but we highly recommend Trane® Clean Effects™. Clean Effects™ has the lowest pressure drop with the highest efficiency possible.
