Recessed ceiling cassettes or low-profile units are also available, and creative placement or custom cabinetry can make them less noticeable while still providing efficient cooling and heating.

61. I noticed you mention energy savings and room-by-room control. Is there an average cost range for installing mini splits in a two-story LA house, and how does it compare to upgrading to a new ducted system?

    1. Installing mini split systems in a two-story Los Angeles home typically costs between $5,000 and $12,000, depending on the number of zones and complexity. In comparison, upgrading to a new ducted system usually ranges from $8,000 to $18,000, especially if new ductwork is needed. Mini splits offer more control and efficiency, while ducted systems can better suit whole-house needs. Exact costs depend on home layout and preferences.

62. Can you explain how the installation process for a mini split works in older Los Angeles homes that don’t have any existing ductwork? I’m wondering if it’s a big project or pretty straightforward.

    1. Installing a mini split in older Los Angeles homes without existing ductwork is usually more straightforward than installing central air. The system just needs small holes in the walls for refrigerant lines and wiring, so there’s minimal disruption to your home’s structure. Most installations take a day or two, making it a relatively quick and clean project.

63. You mention energy savings with mini splits, but how do the installation and long-term maintenance costs compare with traditional central HVAC systems for a typical LA home?

    1. Mini split systems usually have a higher upfront installation cost than central HVAC, mainly because each indoor unit requires separate installation. However, they are more energy efficient, which leads to lower monthly utility bills. Maintenance for mini splits often costs less over time since there’s no ductwork to clean or repair, but you’ll need to service each indoor unit individually. Overall, long-term costs can be lower, especially if you use zoned cooling and heating effectively.

64. When comparing the long-term savings of installing a mini split versus sticking with window units in a small Silver Lake bungalow, what kind of payback period should a homeowner realistically expect?

    1. For a small Silver Lake bungalow, upgrading from window units to a mini split system often results in lower energy bills due to improved efficiency. Typically, homeowners see a payback period of 5 to 8 years, depending on usage habits, insulation quality, and energy rates. The exact timeframe may vary, but mini splits generally provide noticeable long-term savings and enhanced comfort.

65. If a mini split unit stops cooling a particular room, what are some common repair issues I should ask the contractor to check for before considering a replacement?

    1. If your mini split stops cooling a specific room, ask the contractor to check for issues like low refrigerant, a dirty or clogged air filter, blocked or leaking refrigerant lines, electrical connection problems, or a malfunctioning indoor unit fan. Many of these can be repaired without needing a full replacement.

66. For homeowners on a tight budget in Los Angeles, are there any incentives or rebates available that could help offset the cost of installing a mini split system?

    1. Yes, homeowners in Los Angeles may qualify for incentives and rebates to help reduce the cost of installing a mini split system. Local utilities like LADWP and SoCalGas often offer rebates for energy-efficient HVAC upgrades. Additionally, statewide programs sometimes provide extra incentives for high-efficiency systems. It’s a good idea to check these programs’ eligibility requirements and consult with your contractor, who can often assist with the application process.

67. You mention mini splits are energy efficient, but do you have any info on how much they might actually lower utility bills in Los Angeles compared to a traditional central AC system?

    1. Mini split systems can lower utility bills in Los Angeles by 20% to 40% compared to traditional central AC, especially in homes that only need to cool certain rooms. The exact savings depend on your home’s insulation, how often you use the system, and whether you opt for high-efficiency models. Many users notice a significant reduction in summer electricity costs after switching.

68. How does the installation process for mini split systems differ in older bungalows compared to newer condos in LA? Are there specific challenges when retrofitting these systems into homes with unique architecture?

    1. Installing mini split systems in older bungalows often comes with challenges like thicker walls, limited access to electrical systems, and the need to preserve unique architectural features. Newer condos typically have easier access for wiring and mounting units, but may have HOA restrictions. Retrofitting older homes usually requires more careful planning to hide lines and avoid damage to original details.
