Why Redwood Heating & Air San Diego Is Dublin’s Preferred Heat Pump & Mini Split Company
We’ve built our reputation on master-technician diagnosis, not dispatching crews who guess. Gregory Hahn founded this company and still leads every technical decision, bringing 13 years of field experience and a Master Technician designation to every Dublin job. That matters in a city where the housing stock is almost entirely large 2-story tract homes built between 1990 and 2015, with HVAC systems that require real expertise to assess properly.
Our 428 verified customer reviews averaging 4.6 stars reflect that accountability. Dublin homeowners specifically mention our ability to diagnose zoning problems that other companies missed, particularly in the Dublin Ranch and Fallon Village neighborhoods where single-zone systems are the norm. We respond to Dublin calls with the urgency that 100°F+ heat demands, and we stock parts for Trane, Lennox, Goodman, and Rheem systems to minimize wait times.
We’re not a franchise sending whoever’s available. We’re founder-led, brand-agnostic, and we’ve seen the exact failure patterns that Dublin’s climate and housing stock produce. That predictability saves you money and repeat visits.
Our Heat Pump & Mini Split Services in Dublin
Heat Pump Repair
Heat pump repair in Dublin runs $150–$650 depending on the component failure. We see a distinct pattern in this market: Altamont Pass winds carry grassland dust that fouls outdoor condenser coils within a single season, causing efficiency collapse and compressor strain. In the 94568 zip code, we regularly get calls in July and August where the system runs constantly but can’t hold temperature. Gregory Hahn’s brand-agnostic training across nine major manufacturers means we diagnose whether it’s a refrigerant issue, a failed reversing valve, or simply a coil choked with debris, and we fix it without upselling a replacement you don’t need.
Heat Pump Installation
New heat pump installation in Dublin requires sizing for real cooling load, not Bay Area averages. Dublin sits 20–30°F hotter than San Francisco on the same summer day, and many homeowners relocating from the coast underestimate this. We size systems for the actual 100°F+ heat events that blow through the Altamont Pass corridor, and we account for the ductwork leakage common in pre-Title 24 homes. For Dublin Ranch and Fallon Village properties with original single-zone systems, we often recommend heat pump upgrades that pair with zoning solutions rather than repeating the builder’s mistake.
Mini Split Install
Mini split installation is our fastest-growing service in Dublin, and for specific local reasons. A single-zone mini split install runs $3,500–$7,500, with multi-zone systems scaling from there. The typical Dublin scenario: a 2002-built 2-story home where the original ducted heat pump was never designed to cool upstairs bedrooms independently. We recently serviced a home in Fallon Village where the original builder-grade single-zone heat pump couldn’t cool the upstairs master bedroom past 82°F on a 105°F July afternoon. We installed a Daikin multi-zone mini split system with three indoor units, one for the master suite and two for secondary bedrooms, zoning the second floor independently from the main level. The homeowners now keep each room at their preferred temperature without overworking the original ducted unit. This is the upgrade path we recommend most often in Dublin’s master-planned communities.
Mini Split Repair
Mini split repair in Dublin addresses the same dust and wind exposure as heat pumps, plus the specific vulnerabilities of ductless systems: refrigerant line insulation degradation from UV exposure, drain line clogging from fine particulate, and sensor drift from vibration in wind-prone installations. We service all major mini split brands, including Daikin, and we carry common components for faster turnaround. If your mini split is blowing warm air or displaying an error code, we’ll diagnose whether it’s a simple filter cleaning or a compressor issue, and we’ll give you an honest assessment of repair versus replacement.
Multi-Zone System Design
Multi-zone systems are the structural fix for Dublin’s most common HVAC complaint: hot upstairs bedrooms. We design these for the specific layout of Dublin’s large 2-story tract homes, typically 2,000–3,500 square feet with four upstairs bedrooms and an open-plan downstairs. Rather than fighting leaky ductwork and single-zone limitations, a multi-zone mini split gives independent temperature control per room. We’ve installed these in dozens of Dublin Ranch and Fallon Village homes, and the pattern is consistent: homeowners who’ve lived with 82°F upstairs for years are surprised by what proper zoning achieves. Our Heat Pump & Mini Split team handles the full design, load calculation, and installation.

Trusted Brands We Service in Dublin
We service and stock parts for Trane, Lennox, Goodman, and Rheem systems, among others. Gregory Hahn is factory-trained or experienced across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That multi-brand fluency matters in Dublin, where the builder-grade systems installed during the 1990s–2000s construction boom span multiple manufacturers. We’re not locked into selling one brand’s solution. If your existing system is a Lennox and a mini split retrofit with Daikin equipment makes more sense, we’ll tell you. We keep common components in stock to minimize downtime for Dublin customers, and we source less common parts quickly through our supplier network.
Common Heat Pump & Mini Split Problems We See in Dublin Homes
- Upstairs hot spots in 2-story tract homes. Original single-zone heat pumps in Dublin Ranch and Fallon Village were sized for the total square footage, not the actual cooling load distribution. When 105°F air pours through the Altamont Pass, the upstairs gains heat faster than a single zone can remove it. We fix this with multi-zone mini split retrofits, not larger single-zone units.
- Condenser coil fouling from Altamont Pass dust. The same winds that make Dublin hotter than the coast carry fine grassland debris that coats outdoor coils. A dirty coil can reduce heat pump efficiency by 20% or more, and in Dublin we see systems that were cleaned a year ago already choked again. Annual tune-ups are essential here, not optional.
- Ductwork leakage wasting conditioned air. Original ductwork in pre-2005 Dublin homes predates tighter Title 24 sealing requirements. We’ve tested systems where 30% or more of cooled air leaks into attics before reaching rooms. Mini splits bypass this entirely by delivering conditioned air directly.
- Refrigerant leaks in aging builder-grade systems. Heat pumps installed during the 2000s construction boom are now 15–20 years old. Copper line sets degrade, flare connections loosen from thermal cycling, and R-22 systems face refrigerant scarcity. We evaluate whether repair or replacement is the sound investment.
Pricing for Heat Pump & Mini Split in Dublin, CA
We’re upfront about what heat pump and mini split work costs in Dublin. These are the ranges we quote for typical jobs:

| Heat Pump Repair | $150–$650 |
| Mini Split Install (single zone) | $3,500–$7,500 |
| Tune-Up | $80–$200 |
What moves the needle within these ranges? For repairs, it’s parts: a capacitor replacement runs at the low end, while a compressor or reversing valve replacement pushes toward the high end. For mini split installs, the number of indoor units, electrical run length, and whether we need to upgrade your panel are the main variables. Multi-zone systems for full 2-story homes in Dublin Ranch typically fall in the $8,000–$14,000 range depending on zones and capacity. We don’t quote over the phone for installs, we do free in-home estimates with load calculations. Call (844) 875-9451 to schedule.

FAQs — Heat Pump & Mini Split in Dublin
Your 2002 heat pump was likely a single-zone system sized for total square footage, not actual cooling load distribution, and Dublin’s 100°F+ heat waves through the Altamont Pass overwhelm it. The upstairs gains heat faster than ducted air can remove it, especially with original ductwork that leaks into the attic. A multi-zone mini split retrofit is the structural fix we recommend most often for Dublin Ranch and Fallon Village homes. Call (844) 875-9451 for a free assessment of your specific layout.
A single-zone mini split install in Fallon Village typically runs $3,500–$7,500, with multi-zone systems for full 2-story homes starting around $8,000. Most Fallon Village properties need at least two zones upstairs to solve the hot-bedroom problem, and we often add a third for the downstairs living area. We do free in-home estimates with exact load calculations for your floor plan. Call (844) 875-9451 to schedule.
Mini splits are often the better choice for Dublin homes built before tighter Title 24 duct sealing requirements, because they bypass leaky ductwork entirely and deliver conditioned air directly to each room. For Dublin’s 1990s–2000s tract homes with single-zone systems, a mini split retrofit solves the upstairs hot spot problem that ducted upgrades can’t fully address. We evaluate each home individually, but the pattern in Dublin Ranch and Fallon Village strongly favors zoning with mini splits. Call (844) 875-9451 to discuss your specific situation.
We recommend annual tune-ups for Dublin heat pumps, timed before the wind season that fouls condenser coils. The Altamont Pass dust accumulation here is more severe than coastal Bay Area markets, and we’ve seen coils choked within a single season. Our tune-ups run $80–$200 and include coil cleaning, refrigerant check, electrical testing, and filter assessment. Call (844) 875-9451 to schedule before peak summer demand.
Yes, mini splits integrate cleanly with existing ducted systems in Dublin Ranch homes, and this is our most common retrofit approach. We typically zone the upstairs with wall-mounted mini split units while keeping the original ducted heat pump for downstairs service, reducing the load on both systems. This hybrid approach costs less than full replacement and solves the specific upstairs cooling failure that Dublin Ranch homeowners experience. Call (844) 875-9451 for a free estimate on your home’s layout.
