Why Mini-Splits Win in San Jose

Eichler and ranch homes throughout south SJ have low ceilings and original electrical. Three reasons Santa Clara County homeowners choose mini-splits over central HVAC:

1. Efficiency — modern inverter mini-splits run at 22+ SEER2. Old central units in Santa Clara County typically run 13-15 SEER2. The energy bill drops 30-50% in cooling-dominant California climates.
2. No duct losses — central HVAC ductwork in attics loses 20-30% of conditioned air through leaks and heat gain. Mini-splits deliver 100% to the room.
3. Zone control — heat the bedroom at night, cool the office during the day, leave unused rooms uncondoned. Central systems can't do this without expensive zoning.

DIY vs EasyPro vs Multi-Zone

Mr Cool DIY 5th Gen: pre-charged refrigerant lines with quick-connect fittings. Homeowner-installable for someone comfortable drilling exterior walls and running 240V circuit. We finish 60% of "DIY" installs after homeowners hit the electrical or refrigerant-line steps.

Mr Cool EasyPro: pro-install line. Higher SEER2 (up to 24), no quick-connects (refrigerant flared by installer). Always pro-installed.

Multi-zone: 1 outdoor unit, 2-5 indoor heads. Best for full-home conversion. Ducted multi-zone replaces central HVAC entirely.
