Fast, Reliable Air Quality & Ventilation Across Alamo
Air quality and ventilation in Alamo means dealing with real inland heat, wildfire smoke, and the unique demands of large custom homes built between the late 1960s and early 1990s. We’re Crestview Heating & Air California, and we’ve spent nearly two decades helping homeowners in the San Ramon Valley breathe easier — from retrofitting ERV systems on private cul-de-sacs off Livorna Road to upgrading attic ductwork in hillside estates where summer temperatures turn unconditioned spaces into 150°F ovens. If your home is over 3,000 square feet with original ductwork struggling against July heat events, we understand the problem because we’ve solved it in Alamo before. Call us at (844) 560-6978 for a free estimate on your air quality or ventilation project.
Why Crestview Heating & Air California Is Alamo’s Preferred Air Quality & Ventilation Company
Our Air Quality & Ventilation team doesn’t treat Alamo like every other Bay Area suburb. We know that ZIP code 94507 sits in a heat trap behind the coastal hills, where summer afternoons routinely hit 100–105°F — often 25–30°F hotter than San Francisco the same day. That local knowledge changes how we size filtration, specify ERVs, and diagnose duct leakage.
We’ve earned a 4.8-star average across 250+ customer reviews, and Alamo homeowners specifically mention our willingness to crawl through 150°F attics to find the real source of airflow loss. Owner Marcus Feldman serves as our Service Manager, so the accountability isn’t delegated to a dispatcher you’ll never meet. When we quote a MERV-13 upgrade or an ERV retrofit for your custom home, Marcus reviews the static pressure calculations personally.
Our familiarity with Alamo’s private roads and hillside lots means we arrive prepared for homes with multi-zone systems, smart-home integrations, and the long duct runs that define this market. We stock parts for Trane, Lennox, Rheem, and Goodman systems to minimize return trips.
Our Air Quality & Ventilation Services in Alamo
ERV & HRV Systems
Energy Recovery Ventilators and Heat Recovery Ventilators are the right solution for Alamo’s tight, well-insulated custom homes where you need fresh air without dumping conditioned air outside. We retrofitted an ERV system for a custom home on a private cul-de-sac off Livorna Road where the existing ductwork in the unconditioned attic was losing 30% of airflow. Our team installed a Zehnder HRV with MERV-13 filtration, matching the static pressure to the original duct design and integrating it with the homeowner’s smart-home system via a Lennox iComfort thermostat. For Alamo’s 3,000–6,000+ sq ft homes, we size ERV capacity to the actual cubic volume, not a rule-of-thumb formula.
Air Filtration & MERV-13 Upgrades
Fall Diablo winds push hot, dry offshore air and wildfire smoke through the San Ramon Valley, making high-efficiency air filtration a near-necessity in Alamo rather than an upgrade. We install MERV-13 and better filtration systems that capture smoke particulates without choking airflow in older ductwork. Many Alamo homes we service have 1-inch filter slots originally designed for fiberglass pads; we retrofit 4-inch or 5-inch media cabinets that maintain proper static pressure while delivering hospital-grade filtration.
Ventilation Install & Duct Retrofits
Original ductwork in Alamo’s late-1960s-to-early-1990s homes is frequently undersized for modern high-efficiency equipment and inadequate for true cooling loads. On a 103°F summer afternoon, attic temps can reach 150°F+, and duct leakage or poor insulation in those spaces can account for a third of cooling loss before conditioned air ever reaches the living area. We seal with mastic, upgrade insulation to R-8 or better, and resize returns when negative pressure is pulling unfiltered attic air into living spaces.
Whole-House Humidifier & Dehumidifier Installation
Alamo’s hot, dry summers and occasional winter dampness in valley-floor homes create opposite humidity problems depending on season and elevation. We install Aprilaire and Honeywell steam and bypass humidifiers for hillside homes with forced-air heating that strips moisture all winter, and whole-house dehumidifiers tied to your central system for valley-floor properties with basement moisture issues. Both integrate with smart thermostats from Lennox, Trane, and other major brands.
UV Air Purifier Installation
For Alamo homeowners concerned with microbial growth on coils and in drain pans — a real issue when systems run hard for months of 100°F+ weather — we install UV-C lamps at the coil and return. We specify lamp intensity to your system’s airflow rate, not a generic wattage, because an underpowered UV light in a 5-ton system is decorative.

Trusted Brands We Service in Alamo
We service and stock parts for nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Alamo specifically, we see a lot of Lennox and Trane systems in the custom-home market, with Rheem and Goodman common in the semi-custom builds from the 1980s. Our factory training across all nine brands means we’re not guessing when we integrate a new air purifier or ERV with your existing equipment. We carry common filtration media, UV lamps, and ERV core replacements on our trucks, so most Alamo service calls don’t require a parts run that leaves you waiting.
Common Air Quality & Ventilation Problems We See in Alamo Homes
- Duct leakage in superheated attics destroys ventilation efficiency. On 100°F+ days, attic temperatures in Alamo hillside homes reach 150°F+, and leaky flex duct or poorly sealed metal connections bleed conditioned air into that oven. We find 25–35% loss routinely on homes with original 1970s–1980s ductwork.
- Smart-home integration gaps frustrate premium homeowners. Alamo’s custom estates often have automated climate zones, and a noisy or dumb ERV that won’t sync with a Control4, Crestron, or Lennox iComfort system becomes an expensive paperweight. We specify whisper-quiet units with proper BACnet or Wi-Fi integration.
- Undersized original return ducts cause negative pressure. Many Alamo homes were built with returns sized for 3-ton systems that have since been upgraded to 4 or 5 tons. The resulting suction pulls unfiltered attic air through ceiling penetrations, defeating your filtration investment.
- Wildfire smoke events overwhelm standard 1-inch filters. The 2020 and 2022 fire seasons taught Alamo residents that fiberglass or basic pleated filters can’t handle smoke particulate loads. We upgrade to 4-inch MERV-13+ media with pressure-drop calculations to protect your blower motor.

FAQs — Air Quality & Ventilation in Alamo
You need it because Alamo’s fall Diablo winds routinely push wildfire smoke through the San Ramon Valley even when fires are hundreds of miles away, and standard filters can’t capture PM2.5 particulates. Between smoke events, MERV-13 also traps pollen, dust mites, and the fine particulate that gets stirred up during our hot, dry summers. We install 4-inch media cabinets that handle MERV-13 without restricting airflow in older systems. Call (844) 560-6978 for a free estimate on upgrading your filtration.
An ERV will work if your ductwork is properly sealed and sized for the additional static pressure, but many Alamo homes need duct modifications first. We measure actual airflow and leakage before recommending an ERV, because installing one on a leaky system just wastes energy recovering conditioned air that never reaches your rooms. For the Livorna Road project, we sealed and insulated the existing trunk before adding the Zehnder unit. Call us to assess your specific duct configuration.
Yes, most modern whole-house dehumidifiers integrate with smart thermostats including Lennox iComfort, Trane ComfortLink, and popular third-party platforms. We specify units with dry contacts or Wi-Fi modules that report humidity data and accept setpoint commands from your automation system. For Alamo’s premium homes with Control4 or Crestron, we coordinate with your integrator to ensure the dehumidifier appears as a controllable zone.
Your best options are an ERV/HRV with insulated duct runs, or relocating ventilation equipment to conditioned space, because standard fans in 150°F Alamo attics fail prematurely and perform poorly. We often install ERVs in mechanical closets or basement areas with short, sealed duct connections to avoid the attic entirely. When attic installation is unavoidable, we use high-temperature-rated flex duct with R-8 insulation and radiant barrier wrapping. Call (844) 560-6978 to discuss your home’s layout.
You’ll know if your current system has weak airflow at distant registers, noisy returns, or if your contractor had to install a restrictive 1-inch filter because nothing else fits. We measure static pressure across your system and compare it to manufacturer specifications for the air purifier you’re considering. Many Alamo homes built in the 1970s and 1980s have returns sized for 3-ton systems that are now inadequate; we provide a written airflow analysis with any purifier quote. Call for a free assessment.
