How loud are mini splits?
Indoor heads run 19 to 30 dB on low, quieter than a whisper. Outdoor condensers are 45 to 55 dB, similar to a modern refrigerator. Night setback keeps bedroom zones especially quiet.

What do homeowners ask about Mini Splits?
Which brand is best?
Mitsubishi Electric and Daikin lead on reliability and parts availability in the U.S. LG and Fujitsu are also strong. The right pick depends on your zone count, budget, and whether you need hyper-heat performance. We're brand-neutral, we'll recommend based on your situation, not a vendor bonus.
Do mini splits heat as well as cool?
Yes, all modern mini splits are heat pumps that cool and heat. In San Diego's mild climate, heat performance is excellent year-round, you will not need backup heat for a well-sized system.
Can I install a mini split myself?
DIY kits exist, but refrigerant handling is EPA-regulated, a bad flare will leak and fail within a year, and warranty coverage is forfeited without a properly licensed install. A professional install done right the first time costs less than fixing a failed DIY job.
