Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

We know the difference between a year-round residence on Greenway Drive and a seasonal A-frame off Knight Avenue that’s been buttoned up since March. That distinction changes what we bring, what we expect to find, and how we protect your floors and furniture before we open a single panel. Paul Adeyemi built Morton’s Air Duct Cleaning on the idea that families deserve to know exactly what will happen inside their homes and exactly what it will cost. In Big Bear City, that means planning for rodent contamination, wildfire smoke residue, and original flexible duct that has not aged gracefully at 6,750 feet.
Why Morton’s Air Duct Cleaning Is Big Bear City’s Preferred Air Duct Cleaning Company
Big Bear City homeowners call us back because we treat seasonal cabins with the same care as full-time residences. Our technicians arrive in uniform with shoe covers and drop cloths already in hand, background-checked and trained to the Cedarwell C.A.R.E. values. We have found that families in the Moonridge area and along Sugarloaf Boulevard particularly appreciate the photo we send before leaving, proof that the clean-up is complete and the home is left better than we found it.
Dispatch from our Inland Empire office means we coordinate arrival windows that respect mountain driving conditions, not rush-hour freeway estimates. When snow closes Highway 18 or 330, we communicate directly rather than leaving you guessing. The 365-Day Done Right Promise applies to every Big Bear City job, stamped on the work order, not offered only if you ask. And a live person answers the phone 24/7, because a furnace that smells like smoke on a Friday night in January does not wait for business hours.
Air Duct Inspection in Big Bear City
Air Duct Inspection in Big Bear City begins with understanding whether your cabin has been occupied continuously or sealed through multiple seasons, because that history determines what we expect to find. Our inspection covers all accessible supply and return runs, the air handler cabinet, exterior vent screens, and the condition of original duct materials. For a typical Big Bear City inspection, expect $150-$250; if video scoping of buried runs is needed, that extends to $300-$400. We provide a written report with photos before recommending any cleaning or repair.
Seasonal-Reopening Assessments
Cabins vacant for months need a different protocol. We check exterior vents first, because unscreened openings are how mice and squirrels enter. Then we inspect the air handler for nests, droppings, and carcasses before the blower motor distributes contaminants through the house. In Big Bear City, this step is not optional; it is standard practice.
Post-Wildfire Smoke Evaluation
After major San Bernardino National Forest fire events, we inspect return-air systems for ash infiltration that standard filter changes miss. Fine particulates settle in duct-board and flex duct interiors, then recirculate when the system restarts. Our inspection identifies whether cleaning will suffice or if damaged duct sections require replacement.
Residential Air Duct Cleaning in Big Bear City
Residential Air Duct Cleaning in Big Bear City addresses the specific damage done by alpine freeze-thaw cycles, seasonal vacancy, and wildfire smoke exposure that flatland systems rarely face. Our process uses Rotobrush agitation tools with HEPA negative-pressure containment, followed by sanitization when rodent contamination is present. A typical full-system residential clean runs $350-$650; cabins with extensive contamination, crushed flex duct, or multiple HVAC zones reach $800-$1,200. Every price is written and agreed before work begins.
Protecting Your Home During Service
We lay drop cloths from the entry to the air handler and cover furniture near registers. Shoe covers stay on until we exit. For homes with pets, we use quieter tool settings where possible and confirm product choices are pet-safe. Nap schedules matter; we ask about them when booking.
Sealing After Cleaning
Cleaning removes what is inside, but the real fix often happens after. We reseal collar connections, replace deteriorated flex runs, and install vent screens where missing. In Big Bear City, this sealing work prevents the same contamination from recurring the next time the cabin sits empty.
Trusted Brands We Service in Big Bear City
Our vans carry professional-grade equipment from Rotobrush, Nikro, and Aprilaire, brands chosen because they perform at altitude and handle the heavy debris loads common in mountain duct systems. Rotobrush brush-and-vac systems agitate decades of accumulated particulate without damaging fragile original duct-board. Nikro HEPA extractors maintain negative pressure to prevent cross-contamination during rodent-removal jobs. Aprilaire media filters and air cleaners integrate with older HVAC systems common in 1970s A-frames. We stock common replacement collars, flex duct, and vent screen sizes specifically for the cabin construction era dominant in Big Bear City, so most repairs finish same-day without waiting for parts from down the mountain.
Common Air Duct Cleaning Problems We See in Big Bear City Homes
- Active rodent nests in supply and return ducts. Unscreened exterior vents on long-vacant cabins let mice and squirrels enter duct runs directly. We regularly find nests packed against blower motors and carcasses decomposing in flex duct low points, which standard filter changes cannot address and which create health hazards when the system restarts.
- Crushed or separated original flexible duct. Fiberglass duct-board and flex installed in the 1950s through 1980s degrades under Big Bear City’s extreme temperature swings. Runs collapse behind registers, separate at collar connections during HVAC start-up, or crush in attic spaces where snow load and freeze-thaw cycles stress the materials.
- Wildfire smoke and ash infiltration in return-air systems. The San Bernardino National Forest wildfire corridor repeatedly blankets Big Bear City in fine particulates. Ash pulls through return vents, settles in air handlers, and embeds in duct interiors. Surface register cleaning leaves this source contamination untouched; full system agitation and HEPA extraction are required.
- Disconnected runs feeding remote rooms. Original cabin HVAC design often used long flex runs to heat back bedrooms in A-frame layouts. Decades of alpine conditions cause these to sag, disconnect, or develop leaks that rob airflow and allow unconditioned attic air into the system.
Pricing for Air Duct Cleaning in Big Bear City, CA
Most Big Bear City homeowners pay between $350 and $650 for a complete residential air duct cleaning, with larger multi-zone cabins or commercial properties running $500-$1,200. Inspections cost $150-$250, or $300-$400 with video scoping. What moves a job toward the higher end: active rodent contamination requiring Tyvek suits and full respirators, crushed flex duct replacement, multiple HVAC zones, or severe smoke-ash loading after major fire events. We do not price per vent; that model invites bait-and-switch tactics we refuse to use. One flat price per system, agreed in writing before any work starts, every time.

FAQs About Air Duct Cleaning in Big Bear City
The combination is specific to seasonal mountain cabins. Mice and squirrels enter through unscreened exterior vents during vacancy and build nests or die in duct runs, while wildfire smoke particulates from San Bernardino National Forest events settle in return-air systems and reactivate when heated. A standard filter change addresses neither source; full duct inspection, agitation cleaning with HEPA containment, and sanitization are required. Call (323) 918-4345 for an exact quote - estimates are free.
Original flex duct from that era often cannot withstand agitation cleaning after decades of alpine freeze-thaw degradation. We inspect first; if the material is intact, we clean carefully. If it is crushed, separated, or deteriorating, we recommend section replacement, which we can complete same-day with stocked materials. The written price includes either scenario before work starts.
For seasonal-reopening jobs, yes. Active rodent nests, droppings, and carcasses carry hantavirus and other pathogens that require PPE under OSHA guidelines. This is standard protocol on virtually every Big Bear City vacancy job, unlike flatland homes where simple dust loading is the norm. We protect our technicians so we can safely protect your home.
Fine ash and particulates penetrate standard filters and settle in duct interiors, air handlers, and blower motors. When the system restarts, these recirculate through the home. In Big Bear City’s chronic exposure zone, this residue accumulates over multiple fire seasons and requires professional agitation and HEPA extraction to remove, not surface wiping of registers.
We protect floors and furniture with drop cloths, inspect all accessible runs and the air handler, then use Rotobrush agitation tools with Nikro HEPA negative-pressure extraction to remove debris from supply and return ducts. We sanitize when rodent contamination is present, replace damaged flex sections, reseal collar connections, install missing vent screens, and send a photo of the completed clean-up before leaving. The 365-Day Done Right Promise covers everything. Call (323) 918-4345 to schedule.
