Why Crestview Heating & Air California Is Mentone’s Preferred Air Quality & Ventilation Company
We’ve built our reputation in Mentone by showing up prepared for rural properties with longer driveways, detached workshops, and HVAC systems that face genuine winter heating loads. Our 4.8-star average across 250+ customer reviews includes feedback from Mentone homeowners who needed ERV systems that wouldn’t freeze up on south-facing roofs and dehumidifiers sized for monsoonal humidity spikes in older ranch homes with minimal attic ventilation.
Owner Marcus Feldman still serves as Service Manager, which means the person quoting your ventilation upgrade is the same person who’ll make sure your ERV ducting doesn’t terminate where canyon condensation can ice it solid. We’ve been in the HVAC industry for nearly two decades, and that tenure matters in Mentone, where a technician trained on valley design temperatures will undersize your heating capacity and leave you paying for auxiliary heat all January.
We carry factory-trained compatibility across nine major brands, including Trane, Lennox, and Rheem, so your existing equipment never limits what we can recommend. Your system, our specialty. From emergency calls to commercial buildouts, we handle the full scope.
Our Air Quality & Ventilation Services in Mentone
Air Filtration
Mentone’s canyon location means pollen, dust, and wildfire particulates funnel through Mill Creek Canyon with surprising intensity during Santa Ana wind events. We install whole-home media filters and electronic air cleaners that capture particles before they circulate through duct systems already stressed by temperature swings. For homes near Mentone Boulevard or Mill Creek Road, we typically recommend MERV 13–16 filtration paired with sealed ductwork, because the same gaps that draw cold canyon air in winter pull contaminated outdoor air year-round. A whole-home air filtration installation in Mentone generally runs $1,850–$4,200 depending on cabinet size and whether your furnace can handle the static pressure.
ERV/HRV System Installation
Energy recovery ventilators and heat recovery ventilators are essential in Mentone’s older, leakier homes, but placement here is everything. We’ve seen ERV exhaust ducts installed on south-facing roofs where winter condensation freezes solid by morning, blocking airflow for days. Our team sizes ERV/HRV capacity for your home’s actual envelope leakage, not a textbook assumption, and we route ducting to avoid the freeze zones that Mentone’s cold-air drainage creates. ERV/HRV installation in Mentone typically costs $2,400–$5,800. For homes with propane heating, we specify HRVs over ERVs to avoid transferring combustion byproducts back into fresh air streams.
Dehumidifier Installation
Mentone’s summer monsoonal flow brings humidity spikes that standard air conditioners, especially older units in post-war ranch homes, can’t adequately remove. We install whole-house dehumidifiers integrated with your existing duct system, sized for the combined load of outdoor humidity and moisture generated by propane combustion in vented appliances. Undersized units are a common problem we correct in Mentone, where contractors using valley humidity assumptions install equipment that runs constantly without reaching setpoint. Whole-house dehumidifier installation in Mentone runs $1,600–$3,900.
UV Air Purifier Installation
UV-C lamp systems target biological growth on cooling coils and in drain pans, but in Mentone they face an added challenge: propane combustion byproducts accelerate UV lamp degradation in homes with vented heaters or water heaters. We specify higher-grade quartz lamps with extended warranties for propane-heated homes, and we position them where they’ll see maximum coil exposure without premature failure. UV air purifier installation in Mentone typically costs $650–$1,400 per air handler.

Your system, our specialty, whether it’s a decade-old Goodman in a Mentone bungalow or a newer Rheem modulating furnace on acreage off Crafton Avenue.
Common Air Quality & Ventilation Problems We See in Mentone Homes
- ERV ducts freezing on south-facing roofs. Mentone’s cold-air drainage from Mill Creek Canyon creates overnight freeze conditions that valley contractors don’t anticipate. We route ERV exhaust to north or east exposures, or specify insulated risers with drain traps where roof penetration is unavoidable.
- Crawlspace duct leaks pulling canyon air. Many Mentone homes were built with unsealed ductwork in vented crawlspaces. In winter, these gaps draw 28°F air directly into your supply stream. We seal with mastic and proper mechanical fasteners before adding any ventilation equipment, or the new system fights itself.
- Dehumidifiers undersized for monsoonal loads in poorly ventilated attics. Ranch-style homes with original soffit ventilation and no ridge vents trap humidity. A dehumidifier sized for standard conditions runs continuously without reaching target humidity. We assess attic ventilation as part of every dehumidifier quote in Mentone.
- UV lamps degrading prematurely in propane-heated homes. Combustion byproducts from vented propane appliances create a harsher environment for UV lamps. We specify extended-life lamps and check combustion appliance venting as standard practice in Mentone’s propane-served properties.
Pricing for Air Quality & Ventilation in Mentone, CA
Honest pricing for Mentone’s market, calibrated for rural access and the heavier-duty equipment that canyon climate demands:

We Also Serve Cities Near Mentone
Our service radius includes Redlands, Yucaipa, Highland, and Calimesa. Each has different design conditions than Mentone’s canyon microclimate, and we size accordingly. A heat pump that works in Redlands will likely need upsizing for Mentone’s winter heating load. We know the difference because we’ve worked in all four communities.

FAQs — Air Quality & Ventilation in Mentone
Your heat pump was likely sized using Redlands or San Bernardino design temperatures, which don’t account for Mentone’s cold-air drainage from Mill Creek Canyon. When overnight lows drop into the upper 20s, an undersized heat pump can’t maintain setpoint without auxiliary heat, which costs roughly 3x per BTU. We recalculate heating loads using Mentone-specific design temperatures and often find homes need 20–30% more heating capacity than valley sizing suggests. Call (844) 560-6978 and we’ll audit your system against actual local conditions.
Yes, absolutely. An ERV in a home with leaky crawlspace ducts will exhaust conditioned air through those leaks while trying to bring in fresh air, cutting efficiency by 30% or more. In Mentone, unsealed ducts also draw freezing canyon air directly into your supply stream in winter. We seal with mastic and mechanical fasteners as a prerequisite step. Duct sealing for a typical Mentone ranch home runs $1,200–$2,800, and we bundle it with ERV installation when possible.
Probably, if your home is a mid-century ranch with original attic ventilation. Mentone’s summer monsoonal flow brings humidity spikes that older air conditioners, especially those sized for dry-heat assumptions, can’t adequately remove. We see indoor humidity holding above 60% in July and August even when the AC runs constantly. A whole-house dehumidifier integrated with your duct system handles what your AC can’t, and protects against mold in poorly ventilated attics common in Mentone’s housing stock. Call (844) 560-6978 for a humidity assessment.
No, and this matters for safety. A persistent propane combustion smell indicates incomplete combustion or venting issues that need immediate professional attention, not masking with air purification. UV lamps target biological growth on coils, not combustion byproducts. In Mentone’s propane-served homes, we check combustion appliance venting before installing any UV system, and we specify extended-life lamps because propane byproducts do accelerate normal UV degradation. If you smell propane, call your gas provider first, then call us for a combustion safety check.
Yes. We regularly run dedicated ventilation to detached workshops and outbuildings on Mentone’s larger parcels, using inline fans, mini-split-based fresh air systems, or dedicated ERV runs depending on how you use the space. Workshop ventilation in Mentone faces the same canyon microclimate challenges as your main home, plus the complication of longer duct runs. We size for the actual distance and insulation, not guesswork. Call (844) 560-6978 and we’ll walk your property with you.
