We’ve been climbing the East Bay hills to reach Kensington homes for 13 years. Gregory Hahn founded this company and still leads every technical decision, which means when our truck pulls up on Arlington Avenue or Colusa Circle, the person diagnosing your system holds a Master Technician designation, not a training manual from a single-brand factory. Kensington’s hillside streets, tight lots, and pre-WWII housing stock create HVAC puzzles that flatland crews rarely encounter. We know the crawl spaces, the plaster walls, and the marine layer that rolls through Colusa Circle most summer mornings.
Why Redwood Heating & Air San Diego Is Kensington’s Preferred AC Repair & Installation Company
Our reputation in Kensington was built one hillside job at a time. Homeowners here research before they call, and 428 verified reviews averaging 4.6 stars give them something concrete to trust. Many of those reviews mention Gregory Hahn by name, the same technician who founded the company 13 years ago and still shows up when the diagnosis is complex.
Response time to Kensington averages under 90 minutes during business hours. We don’t dispatch from a central warehouse across the Bay; our East Bay routing puts us on Arlington Avenue or up Colusa Circle quickly. That matters when your compressor fails during a September heat spike and your 1920s bungalow traps heat like a brick oven.
We service your brand. Nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Kensington homeowners with mixed systems, older units, or equipment installed by previous owners get brand-agnostic diagnosis instead of a sales pitch for replacement.
Our AC Repair & Installation Services in Kensington
AC Repair
Coastal salt air and marine layer moisture cause outdoor condenser coils to corrode and leak refrigerant within 5-7 years in Kensington, half the lifespan of inland units. We see this on Arlington Avenue and throughout the 94530 zip code. Our repairs address the root cause, not just the symptom. We’ll check coil integrity, test for micro-leaks, and recommend corrosion-resistant coatings where appropriate. Most repairs run $175–$765.
AC Installation
Nearly every installation in Kensington is a retrofit. Pre-WWII homes with wall or floor furnaces have no ductwork, so we design ductless mini-split systems or engineer compact duct runs through tight crawl spaces. We serviced a 1930s Tudor on Arlington Avenue where the original floor furnace was rusted through from decades of coastal moisture. The homeowner wanted central AC, so we retrofitted a ductless mini-split system with an ember-resistant exterior condenser cover, sealed all attic penetrations with fire-rated caulk, and installed a MERV-13 whole-home filter to address smoke concerns, a job only feasible with a heat pump that also handles heating. Installations range $4,130–$8,850.
AC Replacement
When corrosion or age finally wins, replacement demands more than swapping boxes. In Kensington’s 1920s–1950s housing stock, we evaluate whether your existing refrigerant lines can be reused, whether plaster walls will tolerate new line sets, and whether your electrical panel can handle modern efficiency standards. We size systems for moderate cooling loads, real heating demand, and the wildfire-season filtration upgrades that hillside homeowners rightly expect.
Refrigerant Recharge
Low refrigerant in Kensington usually means a leak, not normal consumption. The marine layer accelerates coil pitting at outdoor units, particularly on north-facing slopes where moisture lingers. We leak-test with electronic detectors and nitrogen pressure tests before recharging. Adding refrigerant without finding the leak is a temporary fix that wastes your money and damages your compressor.

Trusted Brands We Service in Kensington
We stock parts and have factory training on Trane, Lennox, Goodman, and Rheem systems commonly found in Kensington homes. Many hillside houses still run 15-year-old Trane XL units or early Lennox Merit systems installed during the last major replacement cycle. Our multi-brand fluency means we don’t force-fit a single manufacturer’s solution onto your specific house. If your Goodman condenser needs a new contactor or your Rheem coil is leaking, we carry the component and complete the repair in one visit. Fast turnaround matters when you’re managing indoor air quality during wildfire season.
Common AC Repair & Installation Problems We See in Kensington Homes
- Corroded condenser coils from marine layer moisture. The salt-laden fog that rolls through Kensington’s hillsides eats copper and aluminum. We find pinhole leaks in coils as young as five years old, far earlier than manufacturers expect for standard inland installations.
- No existing ductwork in pre-WWII homes. Craftsman bungalows and Tudor revivals on Colusa Circle and surrounding streets were built with wall furnaces or gravity heaters. Retrofitting central air means either creative mini-split placement or surgically threading ductwork through original plaster.
- Wildfire ash clogging condenser fins and degrading filters. Kensington sits in the East Bay hills at the edge of a Very High Fire Hazard Severity Zone, the same ridge system scarred by the 1991 Oakland Hills firestorm, meaning HVAC work here uniquely demands ember-resistant vent covers, tightly sealed ductwork to block smoke intrusion, and whole-home filtration upgrades that a flatland neighbor in Richmond or El Cerrito simply wouldn’t prioritize. Technicians working Kensington regularly find that homeowners who lived through or near the ’91 firestorm have strong opinions about attic vent screens and smoke-tight duct sealing, a hyperlocal cultural driver for air-quality upgrades that shapes nearly every service call on the hill.
- Improper mini-split installations by crews unfamiliar with hillside homes. Running refrigerant lines through plaster walls and tight crawl spaces requires experience with Kensington’s specific housing stock. We’ve corrected jobs where lines were kinked, drains improperly sloped, or outdoor units placed without ember protection.

FAQs — AC Repair & Installation in Kensington
Kensington’s hillside elevation channels the marine layer off the Bay directly through the neighborhood, keeping summer highs mild enough that air conditioning is almost never installed, but the persistent coastal moisture accelerates corrosion on outdoor condenser coils and heat exchanger components, shortening equipment life compared to drier inland East Bay cities. Salt-laden fog accelerates pitting in copper tubing and aluminum fins. We recommend corrosion-resistant coatings and more frequent coil cleaning for Kensington installations. Call (844) 875-9451 to schedule an inspection.
Yes, through ductless mini-split systems designed for your specific layout. We’ve installed dozens in Kensington’s craftsman bungalows, running refrigerant lines through exterior walls or tight crawl spaces without destroying original plaster. The outdoor condenser sits on a concrete pad with ember-resistant screening. Call (844) 875-9451 for a free design consultation.
If your home is in or near Kensington’s Very High Fire Hazard Severity Zone, ember-resistant vent covers and tightly sealed ductwork are essential upgrades that we strongly recommend. Standard vent screens melt or allow ember intrusion during wildfire events. We install 1/8-inch mesh ember-resistant covers and seal attic penetrations with fire-rated caulk as part of our hillside installation protocol. Call (844) 875-9451 to assess your current venting.
Heat pumps from Trane, Lennox, and Rheem perform exceptionally well here because Kensington’s moderate heating season and mild cooling demand match their efficiency curves. We size for heating load first, cooling second, since many Kensington homes use the same system year-round. Gregory Hahn selects equipment based on your specific house, not a brand promotion. Call (844) 875-9451 to discuss options.
Once yearly, ideally in early spring before wildfire season begins. The marine layer accelerates coil corrosion and ash accumulation from regional fires strains filtration systems. Our tune-ups include coil cleaning, refrigerant level verification, ember-screen inspection, and filter evaluation. At $95–$235, it’s the cheapest insurance against a mid-summer failure. Call (844) 875-9451 to schedule.
