Frequently Asked Questions About Mini Split Service in Ontario, CA

Repairing a refrigerant leak typically ranges from $200 to $500 depending on the location of the leak (indoor flare joint vs outdoor coil) and the amount of refrigerant required to correctly recharge the system.

Our technicians clear the drain, check for underlying causes like dirty filters or low refrigerant, and prevent recurrence.
Yes a correctly designed multi-zone mini split system can efficiently heat and cool an entire home in California. Our technicians perform a proper load calculation to determine the right system size and zone configuration for your specific home, ensuring every room stays comfortable year-round.
A single-zone system typically takes 4 to 6 hours to install. Multi-zone systems can take 1 to 2 days depending on the number of indoor units, the complexity of the pipe routing through walls, and electrical upgrades required.
