ERV/HRV System in California, CA

ERV/HRV System in San Jose, CA

An energy recovery ventilator (ERV) or heat recovery ventilator (HRV) brings fresh outdoor air into your home while simultaneously exhausting stale indoor air – all without throwing away the energy you’ve already paid to heat or cool. In San Jose’s climate, where homes stay buttoned up for cooling season most of the year and air quality and ventilation issues build quietly behind closed windows, these systems solve a problem that a standard HVAC unit simply can’t touch. If your home feels stuffy, smells musty, or someone in the household deals with persistent allergies or respiratory issues, an ERV or HRV installation is worth a serious look.

At Crestview Heating & Air California, Marcus Feldman has been working with ventilation systems across San Jose for nearly two decades. As both owner and Service Manager, Marcus is involved in every job at the field level – not just on paper. Our team has installed and serviced ERV and HRV units across neighborhoods from Willow Glen to Berryessa, and we know how San Jose’s specific building stock and seasonal patterns affect what system works best and where.

What’s the Difference Between an ERV and an HRV?

This is the first question most San Jose homeowners ask, and it’s the right one to start with. Both systems use a heat exchanger core to transfer energy between outgoing stale air and incoming fresh air. The key difference is moisture.

An HRV (Heat Recovery Ventilator) transfers heat only. It pulls warmth from the exhaust air and uses it to pre-condition the incoming fresh air, but it doesn’t carry humidity along with it. That makes HRVs a strong choice when you want to exhaust excess moisture – think bathrooms, kitchens, or homes with high interior humidity.

An ERV (Energy Recovery Ventilator) transfers both heat and moisture. In San Jose, where summers are dry and homeowners often run humidifiers in winter to keep indoor air from getting too arid, an ERV holds onto that humidity rather than flushing it out. For most San Jose residential installs, ERVs tend to perform better on an annual efficiency basis – but that depends on your home’s specific conditions, which is exactly the kind of assessment Marcus walks through during an on-site evaluation.

Both systems run quietly in the background, typically tied into your existing ductwork, and both recover somewhere between 70% and 85% of the energy that would otherwise be lost in a simple exhaust-only ventilation setup.

When You Need an ERV or HRV System

Not every home in San Jose needs a recovery ventilator, but more do than people realize. Modern construction standards have made homes significantly tighter over the past 20 years – great for energy bills, but hard on air quality. Here are the situations where we most commonly recommend an ERV or HRV installation:

Persistent stuffiness or stale odors indoors. If you’ve had your ducts cleaned and your filters changed but the air still feels dead, the problem is usually ventilation rate – not filtration. A recovery ventilator introduces measured fresh air continuously, which no filter can do on its own.
Allergies or asthma that seem worse at home than outside. San Jose’s Valley heat keeps allergens concentrated indoors during cooling season when windows stay shut. ERV and HRV systems dilute indoor pollutants by cycling in outdoor air, which in most neighborhoods is meaningfully cleaner than recirculated indoor air.
New construction or a recent major renovation. Fresh building materials, adhesives, and paints off-gas VOCs (volatile organic compounds) for months after installation. Homes in newer San Jose developments like Evergreen or the Almaden Valley area frequently show elevated VOC readings for the first year. A recovery ventilator flushes that out steadily without spiking your energy bill.
Elevated CO2 or humidity readings. If you’ve had an indoor air quality test and your CO2 is above 1,000 ppm or your relative humidity swings significantly, a whole-home ERV or HRV is usually the most cost-effective fix.
A very tight, well-insulated home. Homes with spray foam insulation or newer double-pane window packages in San Jose often have infiltration rates low enough that mechanical ventilation is the only reliable way to hit ASHRAE 62.2 ventilation standards.
Home offices or rooms with multiple occupants. Since the remote work shift, we’ve seen a real uptick in calls from San Jose homeowners whose dedicated home offices feel stuffy by midday. Adding ventilation to a room with sustained occupancy makes a noticeable difference.

Our ERV/HRV System Process

We don’t sell systems without understanding the home first. This is the sequence Marcus and our team follow on every ERV or HRV job in San Jose:

Whole-home ventilation assessment. Before recommending a system or quoting a price, we assess your existing HVAC setup, duct layout, current ventilation rate, and the specific areas of the home with the worst air circulation. For many San Jose homes built before 2005, the existing ductwork needs a basic evaluation to confirm it can support balanced ventilation without pressure issues.
System selection and sizing. We size the unit to your home’s square footage and occupancy load, not to what happens to be on a distributor’s shelf. We work with brands including Trane and Lennox, and we’ll match the unit to your existing equipment where possible to simplify maintenance and controls down the road.
Installation and duct integration. Our technicians connect the ERV or HRV unit to your supply and return ductwork, or in some cases run dedicated ventilation duct runs to key areas of the home. We core through exterior walls for the fresh-air intake and exhaust terminations, seal everything properly, and verify that the penetrations are weather-tight – important in San Jose given the occasional heavy winter rain events the South Bay sees.
Balancing and commissioning. This step is where a lot of installations cut corners, and we don’t. We use airflow measurement tools to balance the supply and exhaust sides of the system so the unit is neither over-pressurizing nor under-ventilating the home. A poorly balanced ERV or HRV can actually create air quality problems rather than solve them.
Controls setup and walkthrough. We set up whatever control interface comes with the unit – whether that’s a dedicated controller, a smart thermostat integration, or a tie-in to your existing Trane or Lennox system – and walk you through how to adjust ventilation rates, check filter status, and schedule seasonal service.
Post-installation air quality check. On larger residential installs, we do a basic CO2 and humidity spot-check after the system has run for at least 30 minutes to confirm the ventilation rate is performing as expected before we close out the job.

ERV/HRV System Pricing in San Jose

ERV and HRV installation costs in San Jose vary depending on system size, duct access, and how much new ductwork is needed. Here’s an honest look at the ranges we see in the field:

Scope of Work	Typical Range (San Jose Market)
ERV or HRV unit only (equipment cost)	$600 – $1,400
Standard residential install (tie into existing ductwork)	$1,800 – $3,200
Install with new dedicated duct runs	$2,800 – $4,500
Commercial or multi-unit ERV/HRV installation	Quoted on-site; typically starts at $4,000+
Annual maintenance / filter service	$120 – $220

The biggest cost variables in San Jose are attic access and existing duct condition. Homes in older neighborhoods like Cambrian or Rose Garden sometimes have duct systems that need minor modifications before a recovery ventilator can be balanced properly – that adds labor but we always walk you through it before any work begins. Newer construction in North San Jose or around the Alviso area tends to have cleaner duct layouts and often installs more straightforwardly.

Why San Jose Homeowners Choose Crestview Heating & Air California

There’s no shortage of HVAC companies in the South Bay, and we don’t take it for granted when someone calls us. What we hear consistently from customers – across 250+ reviews that average 4.8 out of 5 stars – is that they stayed with us because Marcus shows up, because we don’t oversell, and because 19 years of field experience means we’ve seen the edge cases that trip up less experienced crews.

ERV and HRV installation isn’t as common as AC repairs or furnace swaps, and not every HVAC company gets enough reps with these systems to do them well. At Crestview, we’ve installed and serviced recovery ventilators from Downtown San Jose to the foothills near Almaden, in everything from 1960s ranch-style homes to newer multi-story builds. The range of systems we work with – including equipment from brands like Trane, Lennox, and Goodman – means we can integrate a ventilation unit with almost any existing HVAC setup without having to tell a customer their system isn’t compatible.

Marcus’s role as Service Manager isn’t a title – it means he’s still out in the field, still doing quality checks, and still accountable when something needs to be made right. That’s different from how most HVAC companies of our size operate, and it’s something 250+ San Jose customers have noticed.

We’re also part of your home’s long-term HVAC picture. ERV and HRV service doesn’t end at installation – filters need to be cleaned or replaced, cores need periodic inspection, and controls sometimes need updating as smart home systems evolve. We handle all of that.

ERV/HRV System Maintenance: What to Expect

Recovery ventilators are low-drama once they’re properly installed, but they do need periodic attention. The filters on most residential ERV and HRV units need cleaning every three to six months, depending on how dusty your home runs. The heat exchanger core itself should be inspected annually – dust and lint accumulate over time and reduce efficiency noticeably if left unchecked.

In San Jose, pollen season runs roughly February through May, and we see filter loading accelerate during that window. If anyone in your household has seasonal allergies, it’s worth scheduling a filter check in late spring rather than waiting for a fixed annual date.

We offer annual maintenance visits for ERV and HRV systems. During a maintenance call, we clean or replace filters, inspect the core and housing, check airflow balance, verify exterior terminations are clear of debris, and confirm the controls are functioning correctly. These visits cost $120-$220 depending on system type and filter count, and they keep the unit running at peak efficiency – which directly affects your HVAC energy costs since a clogged ERV core forces your heating and cooling system to work harder.

FAQs – ERV/HRV System in San Jose

How much does ERV or HRV installation cost in San Jose?

A standard residential ERV or HRV installation in San Jose typically runs between $1,800 and $3,200 when tying into existing ductwork, or $2,800 to $4,500 if new dedicated duct runs are needed. The equipment itself costs $600 to $1,400 depending on brand and capacity. The biggest variables are how accessible your existing ductwork is and whether any modifications are needed for proper airflow balance. Call (844) 560-6978 for a free on-site estimate – we’ll give you a firm number before any work starts.

Is an ERV or HRV worth it in San Jose’s climate?

Yes, for most San Jose homes – especially those built or renovated after 2000. San Jose’s climate keeps homes sealed for a significant portion of the year, which causes CO2, VOCs, and humidity to build up indoors. An ERV or HRV introduces controlled fresh air continuously while recovering 70-85% of the energy in the outgoing air, so you’re not paying to condition fresh air from scratch. Homes with allergy sufferers, home offices, or high occupancy in specific rooms see the most immediate benefit.

Can an ERV or HRV be added to my existing HVAC system?

In most cases, yes. The majority of San Jose homes with central ducted HVAC can accommodate an ERV or HRV installation by tying the unit into the existing supply and return duct system. Homes with Trane, Lennox, Goodman, or most other major-brand equipment can typically be integrated without replacing any existing HVAC components. We assess duct layout and system compatibility during the free estimate visit to confirm the right approach before we recommend anything.

How often does an ERV or HRV need servicing in San Jose?

Filters should be cleaned or replaced every three to six months, and the heat exchanger core should be inspected once a year. San Jose’s pollen season – roughly February through May – tends to accelerate filter loading, so a mid-spring check is worth adding to your schedule if you have allergy-sensitive household members. Annual maintenance visits from Crestview run $120-$220 and cover filters, core inspection, airflow balance check, and controls verification. Call (844) 560-6978 to set up a maintenance plan.

What’s the difference between an ERV and an HRV for a San Jose home?

An HRV transfers heat between outgoing and incoming air but exhausts moisture, making it better suited for homes with excess humidity concerns. An ERV transfers both heat and moisture, which preserves indoor humidity levels – a meaningful advantage in San Jose’s dry summers when homeowners often work to maintain comfortable humidity indoors. For most San Jose residential applications, an ERV performs better on a year-round basis, but the right choice depends on your home’s specific humidity profile. We walk through that during the assessment so you’re not guessing.
