Fast, Reliable Emergency & Commercial HVAC Across Ashland
When the Diablo winds blow and your wall furnace gives out in January, or your rooftop unit fails during a 95-degree October afternoon on E. 14th Street, you don’t have time to wait on a dispatcher in another county. We’re Northstar Heating & Air, and we answer our own phones. Daniel Okafor, our owner and lead technician, has been handling emergency and commercial HVAC calls in Ashland and the surrounding East Bay flatlands for over ten years. From the tract homes near Ashland Avenue to the small commercial strips along Mission Boulevard, we know the 94578 ZIP code’s particular challenges: original wall furnaces, slab foundations that complicate ductwork, and the permitting quirks that come with being unincorporated Alameda County. Call (855) 600-3322 for emergency response or to schedule a free estimate.
Why Northstar Heating & Air San Francisco Is Ashland’s Preferred Emergency & Commercial HVAC Company
Three hundred fifty-seven customers have left reviews, and our average sits at 4.9 stars. That number includes plenty of Ashland homeowners who found us after bad experiences with out-of-area contractors who didn’t understand how permits work here.
Because Ashland is unincorporated, every HVAC permit routes through the Alameda County Building Department in Hayward, not a city office. Daniel has pulled hundreds of these permits. He knows the inspectors, the typical turnaround times, and the documentation that prevents delays. Contractors based in San Jose or even across the line in San Leandro often lose days figuring this out. We’ve seen it happen on jobs we were called in to fix.
Our response time to Ashland typically runs under 45 minutes during emergency hours. We’re coming from San Francisco, but we know the 880 corridor and surface routes through San Leandro well enough to avoid the worst bottlenecks. For commercial clients on Mission Boulevard or near the Ashland BART corridor, that matters when a chiller failure threatens inventory or employee safety.
Daniel personally handles every emergency call. Not a trainee. Not a subcontractor whose name you won’t remember. The same technician who owns the company, stakes his reputation on the outcome, and answers directly if something needs follow-up.
Our Emergency & Commercial HVAC Services in Ashland
24/7 Emergency HVAC
Ashland’s climate lulls people into thinking they don’t need urgent HVAC service, then the Diablo winds arrive. We’ve taken emergency calls at 11 p.m. from families on Dolores Avenue whose wall furnaces failed during a cold snap, and from restaurants on E. 14th Street with walk-in coolers compromised by failing condensers. Our Emergency & Commercial HVAC team carries the parts and tools to handle most same-night repairs on York, Daikin, Bryant, and American Standard systems. Daniel answers the phone directly after hours, so you’re explaining the problem once, to the person who will actually show up.

Commercial HVAC
Ashland’s commercial strip along Mission Boulevard and the smaller retail pockets near Mattox Road rely on rooftop units and split systems that see heavy use during those sudden heat events. We service package units, VAV boxes, and controls for offices, restaurants, and light industrial spaces in the 94578 area. Because we’re certified on nine major brands, we don’t need to subcontract or order unfamiliar parts. A decade of doing this right means we’ve worked on the specific equipment installed in Ashland’s 1960s-era commercial buildings and the newer systems going into renovated spaces.

Rooftop Unit Service
Flat roofs and low-slope commercial structures dominate Ashland’s commercial corridors, and rooftop units are the standard solution. These systems take a beating from Bay Area salt air combined with the dust and debris that Diablo winds carry from the Central Valley. We perform refrigerant leak detection, compressor replacement, economizer repairs, and full changeouts. Daniel has replaced RTUs on Ashland buildings where the original unit was installed before current seismic strapping requirements, a detail out-of-area crews sometimes miss.

Chiller Service
While Ashland isn’t dense with high-rise chiller plants, several medical offices, data rooms, and light industrial facilities in and near 94578 depend on small-tonnage chillers for critical cooling. Chiller failures don’t offer the grace period that comfort cooling might. We handle refrigerant reclamation, compressor rebuilds, and control troubleshooting on systems from multiple manufacturers. For facilities that can’t tolerate downtime, we coordinate temporary cooling while repairs proceed.

Trusted Brands We Service in Ashland
We maintain active certification and hands-on experience with nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Ashland customers, this means no referral runarounds when your system needs work. We stock common parts for York and Daikin systems locally, and our supplier relationships let us source Bryant and American Standard components with next-day turnaround in most cases. Nine major brands, one company, one technician who knows your equipment. That’s the difference between getting back online quickly and waiting for a third-party parts chase.
Common Emergency & Commercial HVAC Problems We See in Ashland Homes
- Wall furnace ignition failures in original units. Many Ashland homes near Ashland Avenue and surrounding streets still rely on wall furnaces installed in the 1950s and 1960s. These units lack modern safety controls, and when the pilot or ignition system fails during a cold Diablo wind night, families are left without heat in homes with no alternative heating source.
- Mini-split overloads during sudden heat spikes. Homeowners who’ve added ductless systems to compensate for the lack of central air find those units working at maximum capacity when temperatures jump from 65°F to 95°F in a single afternoon. Improperly sized systems or blocked outdoor coils fail under that strain.
- Crawl space duct deterioration. The modest tract homes in 94578 often have partial crawl spaces where flexible ductwork was added during later renovations. Rodent activity and moisture from the flatlands’ clay-heavy soil degrade these ducts, leading to sudden airflow loss that owners mistake for equipment failure.
- Commercial thermostat and control failures after power fluctuations. Ashland’s older commercial electrical infrastructure, particularly along Mission Boulevard, can deliver voltage sags during peak demand that scramble programmable controls and leave rooftop units running inefficiently or not at all.
