ERV/HRV System Installation & Service in Los Angeles, CA
An ERV (Energy Recovery Ventilator) or HRV (Heat Recovery Ventilator) brings fresh outdoor air into your home while capturing most of the energy from the air being exhausted – so you’re not paying to heat or cool air that just gets thrown away. In Los Angeles, where homes are sealed tighter than ever for energy efficiency, these systems solve a real and growing problem: Air Quality & Ventilation issues like stale, humid, or pollutant-loaded air that has nowhere to go. If your family is dealing with persistent stuffiness, condensation on windows, or elevated indoor CO2 levels, an ERV or HRV is almost certainly part of the answer.
At Meridian Heating & Air, Anthony Moreno handles ERV and HRV installations personally – as he has for nearly two decades of residential and commercial HVAC work across Los Angeles. You won’t get a subcontractor who’s never touched one of these units before. Call us at (877) 454-5066 to talk through what your home actually needs, or read on to understand how these systems work and what they cost here in the Los Angeles market. Our ERV and HRV work falls under our broader Air Quality & Ventilation in Los Angeles service – a category we treat as seriously as any heating or cooling install.
ERV vs. HRV: Which One Does Los Angeles Homes Actually Need?
This is the first question worth answering clearly, because the wrong choice leads to problems down the road.
An HRV transfers heat between the outgoing and incoming air streams. That’s useful in cold climates where the goal is keeping heat inside during winter. An ERV does the same thing with heat, but it also transfers moisture – which means it can help maintain balanced humidity levels year-round. In Los Angeles, that distinction matters a lot.
Most of the year, Los Angeles sits in a dry, mild-to-warm climate. But the coastal zones – think Santa Monica, Culver City, and Mar Vista – deal with marine layer moisture that pushes indoor humidity up during morning hours. Further inland toward the San Fernando Valley or East LA, the challenge flips: the air is drier, and homes can dip to uncomfortably low humidity in winter months when the heat runs constantly. A Humidifier Install may also help in these conditions. An ERV handles both extremes better than an HRV in most Los Angeles conditions because it manages moisture transfer in both directions. There are exceptions – homes with serious moisture problems or certain commercial applications where an HRV is the right call – and that’s exactly why Anthony assesses each installation individually rather than defaulting to one product.
We work with units from Daikin and Bryant, among others, and we’ll match the system to your actual floor plan, existing ductwork, and the specific How to Improve Indoor Air Quality? (Los Angeles, CA) challenges in your neighborhood before anything gets installed.
When You Need an ERV or HRV System
- Persistent stale or stuffy air despite HVAC running normally. In tightly built homes across Los Angeles – especially newer construction in areas like Playa Vista or mid-century remodels in Silver Lake that have been weatherized – the HVAC recirculates the same indoor air without bringing in fresh air. An ERV or HRV creates controlled ventilation without opening windows to smog or noise.
- Condensation on windows or walls during cooler months. When moisture has nowhere to escape, it settles on the coldest surfaces in the home. In coastal neighborhoods from Westchester to Long Beach, this happens regularly between October and March. Left unaddressed, it leads to mold growth inside wall cavities – a problem Anthony has seen in more than a few older homes during air quality assessments.
- Elevated CO2 or VOC readings on indoor air monitors. If you’ve run a home air quality monitor and seen CO2 climb above 1,000 ppm when the family is home, or if you’ve had flooring, paint, or furniture off-gassing after a renovation, you need mechanical ventilation – not just an air purifier.
- Allergy or asthma symptoms that worsen indoors. This is counterintuitive because people assume outdoor air is the problem in Los Angeles. But sealed homes concentrate pet dander, dust mites, and cooking byproducts to levels far higher than outside. Controlled fresh-air exchange dilutes those concentrations without just flushing conditioned air out the window.
- A recently completed home renovation or new construction. California’s Title 24 energy code increasingly requires mechanical ventilation in new builds and major renovations. If your contractor left a ventilation gap in compliance, or if you want to meet the spirit of the code rather than just the letter, this is the right time to install.
- Commercial spaces with occupancy concerns. Offices, medical suites, and retail spaces in Los Angeles have air quality obligations that go beyond residential. Stuffy conference rooms and high-occupancy spaces benefit directly from the controlled fresh-air delivery that ERV and HRV systems provide.
Our ERV/HRV Installation Process
We don’t do cookie-cutter installs. The process below reflects what actually happens on a Meridian job, not a generic sales pitch.
- Home assessment and air quality baseline. Before we recommend any unit, Anthony walks the home or commercial space to understand the existing HVAC layout, duct access points, square footage, ceiling height, and how well-sealed the envelope is. In Los Angeles, we also factor in neighborhood-specific conditions: coastal humidity, proximity to freeways (which affects outdoor particulate counts), and local building permit requirements. This step usually takes 45 to 60 minutes and shapes every decision that follows.
- System selection and sizing. ERV and HRV units are rated in cubic feet per minute (CFM), and getting the size right matters as much as it does with any air handler. Undersized units don’t provide adequate fresh air exchange; oversized units can depressurize the home or over-dry the air in already-dry inland Los Angeles neighborhoods. We size the unit to ASHRAE 62.2 standards, California’s default ventilation guideline for residential construction.
- Duct design and connection point planning. Most Los Angeles homes have either a central ducted HVAC system or a combination of ducted systems and mini splits. We plan the ERV or HRV duct connections to pull exhaust air from bathrooms and kitchens – where pollutants concentrate – and deliver fresh air to bedrooms and living areas. This isn’t always straightforward in older homes in neighborhoods like Koreatown or Highland Park, where duct layouts were designed decades before mechanical ventilation was a consideration.
- Installation day. Anthony leads the physical installation, including unit mounting, duct connections, exterior intake and exhaust terminations, and electrical connection. We use weatherproof termination caps rated for Southern California’s UV exposure, which matters more than most installers acknowledge. Interior duct runs are sealed with mastic, not just tape. Every penetration in the building envelope gets properly flashed and sealed.
- Commissioning and airflow verification. After installation, we measure airflow at each supply and exhaust point to confirm the system is moving the right volume of air. We also check for any pressure imbalance in the home that could affect how doors close or how the existing HVAC operates. If something’s off, we adjust before we leave.
- Owner walkthrough and filter maintenance schedule. ERV and HRV systems need periodic filter cleaning or replacement – typically every three to six months in Los Angeles given the particulate levels here. Anthony walks you through exactly what your unit needs, where the filters are, and what the warning signs of a clogged core look like. We don’t want a call six months from now because nobody explained the maintenance.
ERV/HRV System Pricing in Los Angeles
ERV and HRV installation in Los Angeles typically runs between $1,800 and $5,500 for a complete residential installation, including the unit, ductwork, terminations, and commissioning. Commercial installations vary more widely based on building size and complexity.
| Scope | Typical Price Range (Los Angeles) |
|---|---|
| Standalone ERV/HRV unit + basic duct connection (existing ductwork used) | $1,800 – $2,800 |
| Full installation with new dedicated duct runs (1,200-2,000 sq ft home) | $2,800 – $4,200 |
| Larger home or complex duct layout (2,000+ sq ft, multi-story, or attic access challenges) | $4,000 – $5,500+ |
| Commercial small office ERV installation | $3,500 – $7,000+ |
What moves the price in Los Angeles specifically:
- Attic access and clearance. Many San Fernando Valley homes have low-pitch roofs with minimal attic clearance. Running duct in those spaces takes significantly more labor than a home with a full attic in, say, Northridge or Granada Hills.
- Exterior wall penetrations. Stucco construction, which covers a large percentage of Los Angeles homes, requires more work to cut, flash, and seal cleanly than wood or vinyl siding.
- Unit brand and CFM rating. Units from Daikin or York at the higher CFM range cost more than entry-level units, and for larger homes that’s often the right call.
- Permit requirements. The City of Los Angeles requires a mechanical permit for ERV and HRV installations in most cases. Permit fees vary by jurisdiction – LA City, LADWP-connected projects, and county unincorporated areas each have slightly different processes. We pull the permit; that cost is included in your estimate.

FAQs – ERV/HRV System in Los Angeles
What’s the difference between an ERV and HRV, and which is right for Los Angeles?
An ERV transfers both heat and moisture between incoming and outgoing air; an HRV transfers heat only. For most Los Angeles homes, an ERV is the better fit because it handles the humidity variation between dry inland air and coastal marine layer conditions more effectively than an HRV. In homes with chronic excess moisture problems – rare in LA but possible in certain hillside or below-grade spaces – an HRV might be the stronger choice. Anthony makes this call after assessing the space, not before. Call (877) 454-5066 if you want a straight answer about your specific home.
How much does ERV/HRV installation cost in Los Angeles?
Most residential installations in Los Angeles run between $1,800 and $5,500 depending on home size, existing ductwork, and the complexity of routing exterior penetrations through stucco construction. Homes in denser neighborhoods like Echo Park or Boyle Heights with limited attic or crawl space access tend to land in the mid-to-upper end of that range due to labor time. Commercial jobs are priced separately based on building specs. Estimates are free – call (877) 454-5066 and we’ll give you an honest number.
Will an ERV or HRV work with my existing HVAC system?
Yes, in most cases. ERV and HRV units can be connected to existing ducted HVAC systems, tied into dedicated duct runs, or in some configurations operated as standalone units with their own supply and exhaust paths. The integration approach depends on your current system layout and what brand of equipment you’re running. We have experience with Daikin, Bryant, York, Rheem, and six other major brands, so compatibility is rarely an issue. What we won’t do is force a connection that compromises your existing system’s performance.
Do I need a permit for ERV/HRV installation in Los Angeles?
In most cases, yes. The City of Los Angeles requires a mechanical permit for ERV and HRV installations because they involve penetrations in the building envelope and connections to the HVAC system. Permit requirements vary slightly between LA City, unincorporated LA County, and municipalities like Burbank or Culver City. Meridian pulls the permit as part of every install – it’s included in your estimate and protects you if you ever sell the home. Call (877) 454-5066 for details specific to your neighborhood.
How often do ERV and HRV filters need to be replaced in Los Angeles?
In Los Angeles, plan on How Often to Replace HVAC Air Filter? (Los Angeles, CA) — every three to four months — rather than the six-month schedule manufacturers suggest for cleaner-air markets. The particulate levels here – especially near freeways in areas like Boyle Heights, Compton, or the 405 corridor – load filters faster than average. A clogged core drastically reduces the system’s efficiency and can eventually damage the heat exchange element. We walk every customer through their specific unit’s maintenance requirements before we leave the job site.
