Ductless Mini Split Installation Services

We install ductless systems for a wide range of home types across South Pasadena. Here are the main services we provide.

Single-Zone Mini Split Installation

A single-zone ductless system pairs one indoor unit with one outdoor condenser. It adds comfort to one room. Perfect for rooms that your central system doesn’t reach well. For instance, a converted attic, a detached garage, or a home office.

Multi-Zone Installation

A multi-zone system connects multiple indoor units to one outdoor condenser. Each room or zone gets its own temperature control. This setup works well for whole-home cooling, where adding full ductwork is not practical.

Wall-Mounted Units

Wall-mounted indoor units are the most common mini split type. They mount high on a wall to deliver quiet airflow. The line set runs through a small opening in the wall to the outdoor condenser. The plaster, trim, and ceilings remain undisturbed.

Floor-Mounted Mini Splits

Floor-mounted units sit near the base of a wall. They are a good option when wall space is limited or when the room has high ceilings that make a wall unit less effective. They also work well in rooms with large windows.

Ceiling Cassette Mini-Splits

These recess into the ceiling and distribute air in four directions. They are a strong option for open-plan homes with limited wall space. They are also more hidden than wall units and can cover a larger area.

Mini Split Heat Pump Installation

Heat pump mini-splits are a practical all-in-one replacement. They provide both cooling and heating, and also don’t use ductwork. They may be more costly upfront, but they deliver major energy savings.

Mini Split Replacement

If you have an older ductless system that is no longer running efficiently, we can replace it with a new unit in the same location.

Why Choose a Mini-Split Over Central AC in South Pasadena?

South Pasadena homes have specific characteristics that make mini-splits a better fit.

Local Historic Homes Cannot Always Accommodate Ductwork

Many South Pasadena homes were built before 1940. Adding central ductwork means cutting through plaster walls, removing crown molding, and lowering ceilings. On the other hand, a mini split runs on a small refrigerant line that passes through a three-inch opening.

You Get Zoned Comfort in Every Room

A central AC cools your entire home to a single temperature. A multi-zone mini-split lets each room run at a different temperature. Your bedroom, home office, and sitting room can be cooled separately. Rooms you are not using stay off, which reduces energy use.

One System Replaces Both AC and Furnace

If your air conditioner and gas furnace are both aging, replacing them separately would mean two large expenses. But if you get a heat pump mini split, you pay once for both needs.

Mini Splits Are Quieter Than Central Systems

Modern inverter mini splits run at very low decibel levels. Sometimes, lower than a quiet conversation. So, mini-splits more easily meet noise reduction standards in residential areas.

Efficiency Ratings Are Higher

Mini-splits operate at high SEER ratings that meet and often exceed Title 24 requirements. Because they deliver air directly without duct losses, they use less energy than a central system working through aging ductwork.

How to Choose the Right Mini Split for Your Home

Choosing the right system is more than picking a brand. Here are the factors that matter most.

  • Room size: Determines how many BTUs to target. A 500-square-foot open space requires about 12,000 BTUs. Oversizing or undersizing your system strains it and can waste energy.
  • Single-zone vs multi-zone: If you are cooling one room, a single-zone system is simpler and more affordable. If you need whole-home coverage, a multi-zone system is the right choice.
  • SEER2 rating: California requires a minimum SEER2 rating of 15.2 for new split system installations.
  • Refrigerant type: Low-GWP refrigerants such as R-454B or R-32 are more eco-friendly.
  • Mount type: Wall-mounted, floor-mounted, and ceiling cassette units all suit different room types.
  • Noise rating: Indoor units are rated in decibels. If the unit is going in a bedroom, look for units rated at 20 to 26 dB on their lowest setting.
  • Smart home compatibility: Most current mini split systems support Wi-Fi control. Some can work with Google Home, Amazon Alexa, and Apple HomeKit.
  • Historic district permit requirements: South Pasadena’s Planning and Building Division requires mechanical permits for mini split installations. Homes in historic districts may also require review of exterior condenser placement.

How Much Does a Mini Split Installation Cost?

A single-zone system costs between $3,000 and $5,000 installed. This covers the equipment, line set, and labor for a standard wall-mounted unit. Multi-zone systems range from $5,000 to over $15,000, depending on the number of indoor heads.

Mini split installation costs in South Pasadena vary based on the number of zones, the equipment selected, and the complexity of the installation.

Historic homes may increase costs if the line set needs to be routed discreetly to avoid damaging original walls or trim. Panel upgrades can also increase the final price.

About South Pasadena, CA

South Pasadena is a small incorporated city of about 26,000 people in Los Angeles County. It is bordered by Pasadena to the north and Alhambra to the south. The city holds a formal “City of Trees” designation, with street trees lining nearly every residential block.

The Arroyo Seco Parkway runs along the city’s western edge and was the first freeway built in the western United States. It is also listed on the National Register of Historic Places as a federal historic landmark.

South Pasadena has one of the most active historic preservation programs in the San Gabriel Valley. The city maintains a Cultural Heritage District and reviews proposed exterior changes to properties within it.

Top landmarks include:

  • Fair Oaks Avenue Farmers Market
  • Rialto Theatre
  • Arroyo Seco Parkway

Frequently Asked Questions

Is South Pasadena the same as Pasadena?

No. South Pasadena is a separate city with its own council, police department, and planning department.

South Pasadena borders Pasadena to the north, Alhambra and San Gabriel to the south, and San Marino to the east. Los Angeles (El Sereno and Highland Park) borders it to the west. Arcadia, Monrovia, and Temple City are a short drive east.

The main drawbacks are the upfront cost and visible indoor units. A multi-zone system that covers an entire home costs more than a basic central AC replacement. The indoor wall units are visible, which some homeowners prefer to avoid.

A well-maintained mini split lasts 15 to 20 years. Annual maintenance helps to ensure your system lasts as long as it should.

You should not place a mini split indoor unit directly above beds or seating. You should also avoid placing it near heat sources, such as a stove. Outdoor condenser units should not be installed in enclosed spaces with poor airflow or in direct contact with vegetation.

No. Mini splits are designed for continuous operation. Inverter compressors modulate their speed rather than cycling fully on and off. Therefore, running the system around the clock uses less energy than you might expect.

A 12×12 room is 144 square feet. So, you need about a 9,000 BTU unit. In South Pasadena, where summer temperatures can be high, a 9,000 to 12,000-BTU unit provides more reliable cooling during peak heat.
