Fast, Reliable Emergency & Commercial HVAC Across Tujunga
When your furnace quits on a January night or your rooftop unit locks out before opening, you need someone who knows Tujunga, not just the Valley. We’re Meridian Heating & Air Los Angeles, and we’ve been responding to emergency calls in the 91042 and 91043 zip codes for nearly two decades. Anthony Moreno, our founder, still shows up on the job, whether it’s a midnight compressor failure off Foothill Boulevard or a commercial chiller issue near the Big Tujunga Canyon mouth. Call us at (877) 454-5066 for emergency service or a free estimate.
Why Meridian Heating & Air Los Angeles Is Tujunga’s Preferred Emergency & Commercial HVAC Company
Tujunga isn’t flat Valley. The elevation, the canyon winds, and the post-fire ash load here create HVAC problems you won’t find in Burbank or Glendale. We’ve spent 19 years learning those differences the hard way, on actual service calls.
Our 286 verified reviews average 4.8 out of 5 stars, and a solid share of them come from Tujunga homeowners and small business owners who’ve called us back multiple times. They mention the same things: Anthony shows up on the job, diagnoses the real problem instead of pushing a replacement, and knows how their specific system behaves in this microclimate.
Response time matters in emergencies. We’re based in Los Angeles with routes that prioritize the foothill communities, and our Emergency & Commercial HVAC team carries the parts and tools to handle most same-day repairs on the brands we see most in Tujunga: Trane, Lennox, Goodman, and Rheem.
We also understand the local housing stock. Tujunga’s post-WWII ranch homes and bungalows, many originally built with wall furnaces or floor heaters, have ductwork retrofits that create chronic airflow problems. We don’t treat them like standard new construction because they aren’t.
Our Emergency & Commercial HVAC Services in Tujunga
24/7 Emergency HVAC
Furnace failures at 2 a.m. Compressor lockouts during a Santa Ana wind event. We take emergency calls seriously because Tujunga’s temperature swings don’t wait for business hours. That January hard frost at 1,500 feet elevation isn’t theoretical, it’s what your heat pump is fighting at midnight. Our emergency line connects directly to Anthony or a senior technician, not a call center.

Commercial HVAC
Small-to-mid-size commercial properties in Tujunga, from retail strips along Foothill Boulevard to office spaces near the canyon mouth, need systems that handle real dual-season loads. We install, repair, and maintain package units, split systems, and controls for businesses that can’t afford downtime. Our commercial work includes load calculations that account for Tujunga’s diurnal temperature swings, not just summer cooling peaks.

Rooftop Unit Service
Rooftop units in Tujunga fight a uniquely hostile environment. The canyon geography funnels Santa Ana winds directly across flat commercial roofs, packing condenser coils with dust and debris while the units run at high ambient temperatures. We responded to a 24/7 emergency call on Foothill Boulevard where a Trane condenser locked out after a Santa Ana event packed its coils with ash and debris. Assessment showed compressor overheating from restricted airflow; we cleaned the coils, verified charge, and installed a pre-filter screen to extend intervals between cleanings. That kind of field experience shapes how we approach every rooftop unit in this zip code.

Chiller Service
Commercial chillers in Tujunga face the same ash and debris load as rooftop units, plus the added strain of serving buildings that may have been expanded without corresponding chiller capacity upgrades. We service and repair chillers from major manufacturers, with particular attention to condenser water loops and cooling towers that clog faster here than in flat Valley locations.

Annual Maintenance
Standard quarterly maintenance schedules fail in Tujunga. The 2009 Station Fire and subsequent burn cycles in the Verdugo and San Gabriel foothills above the community mean periodic ash and particulate events measurably shorten filter service intervals and coat condenser coils far more than in flat Valley cities. Our annual maintenance program for Tujunga properties includes post-fire-season coil cleaning as a standard recommendation, not an afterthought. This isn’t upselling, it’s what the local conditions actually demand.

HVAC Inspection
Buying a home or commercial property in Tujunga? Our inspections focus on the legacy issues this housing stock presents: undersized ductwork from wall-furnace retrofits, oversized replacement units installed without proper load calculations, and heat exchangers compromised by years of condensation and soot buildup. We document what we find with photos and plain-language explanations, so you know what you’re walking into.

Trusted Brands We Service in Tujunga
We work on your brand, not just ours. Anthony has factory training or deep field experience on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Tujunga customers, that means we stock common parts locally and can often source same-day replacements for less common components through our distributor relationships. We don’t try to sell you a new system because we don’t have the part for your existing one. Whether it’s a 15-year-old Goodman furnace in a Foothill Boulevard bungalow or a Trane rooftop unit serving a commercial strip, we’ve worked on it before.
Common Emergency & Commercial HVAC Problems We See in Tujunga Homes
- Condenser coil fouling from post-fire ash and Santa Ana dust. The canyon geography drives debris directly into outdoor units, causing high-pressure cutouts and premature compressor failures. Standard quarterly maintenance schedules miss the ash load entirely; we see units that ran fine in April lock out by July.
- Undersized or deteriorating ductwork from post-WWII wall furnace retrofits. Many Tujunga homes had central air added decades after original construction, with duct runs squeezed through attics and crawlspaces that were never designed for it. The result is chronic airflow imbalance, hot and cold rooms, and systems that short-cycle themselves to death.
- Furnace heat exchanger and burner issues from improperly sized replacements. When oversized units get installed without proper load calculations, they cycle on and off too quickly, never reaching steady-state operation. Condensation builds in the heat exchanger, soot accumulates on burners, and efficiency drops while safety risks rise.
- Compressor failures from high-ambient operation during Santa Ana events. Tujunga’s outdoor temperatures spike during canyon wind episodes, but the bigger problem is the debris load that restricts airflow just when the unit needs it most. We’ve replaced compressors that failed not from age, but from running head pressures 30% above design.

FAQs — Emergency & Commercial HVAC in Tujunga
We can often repair wall furnaces and floor heaters from the 1950s and 1960s, provided parts remain available for the specific manufacturer and model. If the heat exchanger is cracked or the unit has been retrofitted with unsafe modifications, we’ll recommend replacement and explain whether your existing ductwork can handle a modern forced-air system or if a mini-split heat pump makes more sense for your bungalow’s layout. Call (877) 454-5066 for a free assessment.
At minimum, condenser coils in Tujunga need professional cleaning once annually, timed for late fall after fire season ends. Standard quarterly maintenance schedules designed for flat Valley cities miss the fine mineral ash that settles here from burn zones above the community. We also recommend checking and replacing filters every 30–60 days during active ash events, rather than the typical 90-day interval. Call (877) 454-5066 to schedule post-fire-season coil cleaning.
High-pressure lockouts on Tujunga rooftop units almost always trace to restricted condenser airflow from Santa Ana debris and post-fire ash accumulation, sometimes compounded by overcharging or failed condenser fans. The canyon wind pattern here packs coils faster than in Burbank or Glendale. We clean the coils, verify refrigerant charge with subcooling and superheat measurements, and often install pre-filter screens to extend cleaning intervals. Call (877) 454-5066 for emergency diagnosis.
Crawlspace ductwork from post-WWII retrofits can often be cleaned if the metal or flex runs are intact and properly sealed, but we frequently find deterioration, disconnection, or original sizing that’s 30–40% too small for the current system. We inspect with cameras, test airflow at each register, and give you honest numbers: cleaning and sealing versus full replacement with properly sized runs. Many Tujunga homes benefit from partial replacement of the worst sections rather than full gut jobs. Call (877) 454-5066 for a crawlspace duct evaluation.
Yes, we provide 24/7 emergency HVAC service for both residential and commercial properties in Tujunga, including rooftop units, chillers, and package systems.
