Residential Ventilation Services in Healdsburg, CA

Supply-Only Ventilation

This approach does the opposite. It brings fresh outdoor air into your home through a dedicated fan, creating positive pressure that pushes stale air out through building envelope leaks. You get to control where the fresh air comes from and can filter it before it enters your living space.

The advantage? Filtered fresh air delivery. The downside? In humid weather (hello, Russian River moisture), you’re bringing that humidity inside with no way to manage it. And like exhaust-only systems, you’re wasting energy by not capturing any heat or cooling from your outgoing air.

Balanced Ventilation with Energy Recovery

This is where things get smart. Balanced ventilation systems bring in fresh air and exhaust stale air in equal amounts. More importantly, they use an energy recovery core to transfer heat between the outgoing and incoming air streams without mixing them.

Energy Recovery Ventilators (ERVs) transfer both heat and moisture. In summer, your cool, dehumidified indoor air pre-cools and dries the hot, humid outdoor air before it enters your home. In winter, your warm indoor air preheats the cold outdoor air. You get fresh air without the massive energy penalty.

Heat Recovery Ventilators (HRVs) work similarly but only transfer heat, not moisture. They’re better for homes that need to shed excess humidity, like properties near Healdsburg Memorial Beach or along the Russian River where moisture is always a concern.

For most Healdsburg homes, especially in neighborhoods like Fitch Mountain residential area or along Healdsburg Ridge where homes are well-built and energy efficiency matters, ERV systems make the most sense. You’re following ASHRAE 62.2 requirements, meeting California Title 24 compliance, and actually lowering your heating and cooling costs compared to simpler systems.

How Proper Ventilation Solves Real Problems

Most people call us because they’re experiencing specific issues, not because they woke up thinking about air changes per hour. Let’s talk about the problems ventilation actually fixes.

Wildfire Smoke Management

If you’ve lived in Healdsburg through fire season, you know the drill. The sky turns orange, the Air Quality Index climbs into the unhealthy range, and you seal up the house. But what then? You’re trapped inside with whatever air quality you already had, and it slowly degrades.

A properly designed ERV or HRV system with MERV-13 or HEPA filtration gives you continuous fresh air even when outdoor air quality is terrible. The filters capture PM2.5 particulates (the most dangerous component of wildfire smoke) before they enter your home. You maintain healthy indoor air without opening windows or running your home into negative pressure that would suck smoke through every crack.

This matters a lot for properties in the Dry Creek Valley corridor and Alexander Valley areas where wildfire risk runs higher. But even downtown near the Plaza, smoke impacts everyone during fire season.

Bathroom and Kitchen Moisture

Every shower sends moisture into your home’s air. If that moisture can’t escape, it condenses on cold surfaces. You’ll see it on windows first, but it’s also condensing inside wall cavities where you can’t see it. That’s where mold grows.

Proper bathroom exhaust fans sized to CFM requirements (typically 50-80 CFM for standard bathrooms) and ducted all the way outside solve part of this. But whole-house ventilation ensures that moisture doesn’t just move from the bathroom to the bedroom. It actually leaves your home.

For older homes in Old Town Healdsburg or Victorian properties around University Street and Matheson Street, this becomes critical. These homes often lack the vapor barriers and wall insulation that modern homes use to manage moisture. Continuous ventilation helps protect your home’s structure.

Cooking Odors and Indoor Air Pollutants

Your kitchen range hood should exhaust at least 100 CFM for electric ranges, more for gas. But most homeowners don’t run their range hoods enough, and recirculating hoods that just filter and blow air back into the kitchen do almost nothing.

Continuous whole-house ventilation picks up where your range hood leaves off. It dilutes and exhausts cooking odors, combustion byproducts (if you have gas appliances), and VOCs from cleaning products before they build up to irritating levels.

Allergies and Indoor Air Quality

If allergies bother you more inside than outside, poor ventilation is likely part of the problem. Dust, pet dander, pollen that makes it indoors on clothes and shoes, and other allergens accumulate in stagnant air. An ERV or HRV system with proper filtration continuously dilutes these pollutants while capturing new ones before they enter.

For families with asthma or other respiratory conditions, this isn’t just about comfort. It’s about health. And when you combine mechanical ventilation with upgraded MERV-rated air filters in your HVAC system, you’re creating multiple layers of protection.

What a Professional Installation Involves

We don’t just bolt a fan to your house and call it ventilation. A proper whole-house ventilation system requires careful planning and execution.

System Sizing and Design

First, we calculate your home’s ventilation requirements using ASHRAE 62.2 formulas. These consider your home’s square footage, number of bedrooms, and existing infiltration rate. A 1,500-square-foot home with three bedrooms needs different airflow than a 2,500-square-foot home with four bedrooms.

We perform Manual J load calculations to understand how ventilation impacts your overall heating and cooling loads. This helps us select ERV or HRV equipment that delivers the required CFM without oversizing (which wastes energy and money) or undersizing (which fails to meet code and leaves you with poor indoor air quality).

Equipment Selection

Not all ERV and HRV equipment performs equally. We look at energy recovery efficiency (the percentage of heat and moisture transferred between air streams), fan efficacy (measured in CFM per watt), and noise levels. Nobody wants a ventilation system that sounds like a jet engine.

For Healdsburg homes, we typically install systems with 70-85% energy recovery efficiency. Higher efficiency means lower operating costs and better comfort. We also make sure the unit can accommodate MERV-13 filters at minimum, with the option to upgrade to HEPA if needed during wildfire season.

Ductwork and Distribution

The ventilation system needs its own dedicated ductwork separate from your heating and cooling system. We install supply air ducts to deliver fresh air to living areas and bedrooms, and exhaust air ducts to remove stale air from bathrooms, laundry rooms, and kitchens.

Duct sizing matters. Undersized ducts create pressure drop, reduce airflow, and make the system noisy. We use sheet metal ductwork where possible for durability and seal all connections with mastic sealant, not just tape. For attic installations common in Healdsburg homes, we make sure ducts are properly insulated with vapor barriers to prevent condensation.

Fresh air intake and exhaust outlet locations matter too. We locate them to avoid short-circuiting (where exhaust air immediately gets pulled back in) and to keep exhaust away from windows, doors, and outdoor living spaces. For properties with tight lot lines near downtown or along Healdsburg Avenue, this takes careful planning.

Controls and Integration

Modern ERV and HRV systems integrate with your existing HVAC system and smart thermostats. We can set them up to run continuously at low speed, ramp up when indoor CO2 levels rise, or coordinate with your heating and cooling equipment to maximize efficiency.

For homes with ventilation controls and timers, you’ll have the ability to override the system when needed (like during extreme wildfire smoke events when you want to minimize outdoor air intake temporarily). Humidity sensors can trigger additional ventilation when moisture levels spike.

Title 24 Compliance and Permits

All our installations meet California Title 24 requirements and local Healdsburg building code. We pull proper permits, submit energy compliance documentation, and coordinate inspections. This protects you during home sales and ensures your system qualifies for any available rebates.

Maintenance and Long-Term Performance

A ventilation system isn’t install-it-and-forget-it. Regular maintenance keeps it running efficiently and protects your investment.

Filter Replacement

This is the big one. Ventilation system filters need replacement every three to six months depending on outdoor air quality and system runtime. During wildfire season in Sonoma County, you might need to change filters monthly. We offer filter replacement services, or we can show you how to do it yourself. It’s not complicated, but it needs to happen consistently.

Core Cleaning

The energy recovery core should be cleaned annually. This involves removing it from the unit and either vacuuming it or washing it with mild detergent, depending on the manufacturer’s requirements. A dirty core reduces efficiency and airflow.

Duct Inspection

Every few years, we recommend inspecting ventilation ductwork for accumulated dust, signs of moisture intrusion, and seal integrity. Duct sealing that fails allows unconditioned attic or crawlspace air into your system, defeating the purpose of having balanced ventilation.

Airflow Testing and Balancing

Over time, airflow rates can drift from design values. We can perform airflow testing to verify your system still meets ASHRAE 62.2 requirements and rebalance if needed. This involves measuring CFM at supply and exhaust points and adjusting dampers.

Energy Efficiency and Operating Costs

One of the biggest concerns homeowners have about ventilation is cost. Will running a ventilation system constantly spike your PG&E bill?

With a properly sized ERV or HRV system, the answer is usually no. In fact, you’ll typically spend less on heating and cooling than you would with exhaust-only or supply-only ventilation, even though you’re bringing in more fresh air.

Here’s why. Energy recovery. An ERV with 75% efficiency recovers three-quarters of the heating or cooling energy that would otherwise be lost. During a Sonoma County summer when outdoor air is 95°F and your indoor air is 75°F, the ERV pre-cools incoming air to about 80°F. Your air conditioning only needs to handle that 5° difference, not the full 20° difference.

In winter, the same principle applies. Instead of heating 35°F outdoor air to 70°F, you’re heating 55°F air to 70°F. That’s a huge difference in energy consumption.

The fan power consumption matters too, but modern EC (electronically commutated) motors are remarkably efficient. Most residential ERV systems consume 50-150 watts, less than a couple of light bulbs. Run continuously, that’s $5-15 per month at typical PG&E rates.

For homes with solar panels (increasingly common in neighborhoods around Healdsburg Ridge and Fitch Mountain), ventilation system energy consumption barely registers. You’re producing way more power than the ventilation system uses.
