If you’re cooling a room addition, garage, sunroom, or home without existing ductwork, a ductless mini-split air conditioning system may be the perfect solution. Davis Plumbing and Heating Inc. installs mini-split systems throughout Riverside County — Murrieta, Temecula, Menifee, Perris, Lake Elsinore, and beyond.

What Is a Ductless Mini-Split?

A mini-split consists of an outdoor compressor unit connected to one or more indoor air-handling units via a small conduit (containing refrigerant lines, electrical wiring, and a condensate drain). They require no ductwork — just a 3-inch hole through the wall for the conduit. Most units provide both heating and cooling (heat pump mode), making them year-round comfort systems.

Why Mini-Splits Are Ideal for Riverside County Homes

  • Perfect for room additions and ADUs — If your home has a garage conversion, guest house, or room addition that’s not connected to your central HVAC system, a mini-split is the most cost-effective comfort solution.
  • Excellent energy efficiency — Mini-splits have SEER ratings of 18–25+ (compared to 14–18 for central systems), significantly cutting cooling costs during long Riverside County summers.
  • Zone control — Each indoor unit has its own thermostat, so you only cool the rooms you’re using. Multi-zone systems can serve 2–5 rooms from a single outdoor unit.
  • No duct losses — Central AC systems lose 20–30% of cooling capacity through leaky ducts. Mini-splits deliver cooling directly to the space, with no duct loss.
  • Whisper quiet operation — Indoor units operate at 19–26 decibels — quieter than a library.

How Much Does Mini-Split Installation Cost in Riverside County?

  • Single-zone (1 indoor unit) — $2,500–$4,500 installed, depending on BTU size and brand.
  • Multi-zone (2–4 indoor units) — $4,500–$9,000+ installed.
  • Popular brands Davis Plumbing installs: Mitsubishi, Daikin, LG, Samsung, and Carrier.
