Mechanical Ventilation for Sealed Homes in Paradise
Paradise is one of the few residential communities in Southern Nevada where opening a window is genuinely impractical for most of the year. Airport noise from Harry Reid International's approach corridors, summer temperatures that peak above 110°F for weeks at a time, and the Strip's constant ambient sound keep windows closed on a near-permanent basis for most residents. The result is what building scientists call a tight building envelope — which is excellent for energy efficiency but creates an indoor air quality problem that only mechanical ventilation can solve. Stale air, elevated CO2, cooking odors, and moisture from daily activities accumulate in sealed homes without a mechanical fresh air supply. In Paradise specifically, the urban density adds pool chemical off-gassing from adjacent properties and vehicle emission infiltration from the heavy commercial traffic on Tropicana, Maryland Parkway, and Paradise Road.
Quick guidance: Paradise homes with permanently closed windows need mechanical ventilation — not just air filtration. An ERV (Energy Recovery Ventilator) brings in fresh outdoor air while capturing 70–80% of the cooling energy from the exhaust air stream, so you're not paying to cool fresh air from scratch. Call (702) 567-0707 to assess your home's ventilation needs.
What Air Ventilation Service Includes

- CO2 monitoring integration — Installing CO2 sensors to automate ventilation increase when occupancy or activity raises CO2 above 1,000 ppm.
Why Paradise's Urban Conditions Make Ventilation Non-Negotiable
Building tightness in Paradise exists on a spectrum. 1960s and 1970s ranch homes in Paradise Palms leak air at rates of 10–20 ACH50 (air changes per hour at 50 pascals of pressure) — these leaky homes get infiltration ventilation whether the occupants want it or not, though the source is uncontrolled outdoor air of variable quality. Newer construction and renovated homes in Paradise, particularly condos and townhomes built after 2000, can achieve 3–5 ACH50, which is tight enough to trigger ASHRAE 62.2's mechanical ventilation requirements. At these tightness levels, the building code requires mechanical fresh air supply — yet many homes in this range have only exhaust fans that create negative pressure, drawing unconditioned air through envelope gaps rather than providing truly fresh, filtered, conditioned air.
Paradise's urban heat island effect reaches its maximum intensity here — ambient temperatures 5–10°F above surrounding areas, with commercial buildings, asphalt parking lots, and the Strip infrastructure radiating heat at night. The conventional answer to summer heat in Nevada is to open windows at night to flush out accumulated heat. That strategy doesn't work in Paradise: nighttime temperatures at the urban core don't drop below 90°F during most July and August nights, and when they do, the airport, the Strip, and road traffic make fresh-air cooling by natural ventilation impractical. Mechanical ventilation with an ERV solves this by bringing in controlled amounts of fresh air at the right times — typically timed to when HVAC capacity can efficiently condition the fresh air load — without adding the noise and security concerns of open windows.
Pool chemical off-gassing is a specific Paradise concern that surprises residents. The combination of high pool density (many Paradise apartment complexes and condo communities share pools), high evaporation rates in the desert heat, and frequent chemical treatment creates chloramine and chlorine off-gas that drifts at low concentrations through adjacent properties. During summer months when pool chemical use peaks, this contributes measurably to indoor VOC levels for homes with inadequate envelope separation from pool equipment areas. An ERV with activated carbon pre-filtration on the outdoor air intake addresses this specifically.
What to Expect From a Ventilation Project
- Building tightness assessment — We evaluate construction type and era to estimate current infiltration level and determine whether ASHRAE 62.2 mechanical ventilation is required or strongly recommended.
- Fresh air requirement calculation — Using ASHRAE 62.2 formula: 0.01 CFM per sq ft of floor area + 7.5 CFM per person (estimated by bedroom count). A 1,500 sq ft 2-bedroom Paradise home requires approximately 37.5 CFM continuous fresh air supply.
- ERV/HRV selection — Selecting a unit sized for your calculated ventilation rate with appropriate sensible and latent effectiveness ratings for Las Vegas's hot-dry climate. ERVs (which transfer both heat and moisture) are preferred in our climate over HRVs, which transfer only heat.
- Duct design — Planning balanced supply and exhaust duct pathways that distribute fresh air throughout occupied spaces rather than directly short-circuiting to the exhaust.
- Installation and commissioning — Installing the ERV, running duct, connecting to the HVAC system or providing standalone distribution, and measuring actual airflow at supply and exhaust points to verify balanced operation.
- Controls setup — Configuring ventilation schedule, boost mode for cooking and bathing, and CO2-based demand control if monitoring is installed.

Common Questions About Air Ventilation in Paradise
Why can't I just crack a window if I want fresh air?
You can — but in Paradise specifically, the calculus is unfavorable. July and August outdoor temperatures stay above 100°F until late afternoon and above 90°F most nights. Airport noise keeps windows closed for comfort in most of the community. Vehicle and commercial activity on nearby corridors means outdoor air quality near busy roads is actually worse than indoor air quality with basic filtration. An ERV gives you fresh air — filtered, partially conditioned — without any of those trade-offs.
What's the difference between an ERV and an HRV, and which is better for Paradise?
Both transfer heat between incoming and outgoing air streams. An ERV also transfers moisture — when hot humid outdoor air comes in, the ERV transfers some of that moisture to the dry exhaust air, which reduces the humidity load on your air conditioning system. An HRV transfers heat only. In Las Vegas's desert climate, the summer outdoor air is hot but dry — moisture transfer in an ERV during summer actually helps reduce cooling load slightly. In winter, the ERV retains indoor humidity that would otherwise be purged with an HRV. For most of the year and most homes in Paradise, an ERV performs better than an HRV.
My Paradise apartment has only one exhaust fan in the bathroom. Is that adequate ventilation?
For a sealed apartment, almost certainly not. Building code requires bathroom exhaust fans, but the standard requirement — 50 CFM intermittent or 20 CFM continuous — is a code minimum, not an optimal indoor air quality target. A single bathroom fan cannot provide balanced ventilation: it creates negative pressure that draws air through envelope gaps, not the filtered, distributed fresh air supply that balanced mechanical ventilation provides. If you're in an apartment without ERV, your options are limited to what the building management controls. For Paradise landlords, adding ERV to apartment buildings is an air quality and habitability improvement worth discussing with us.
How much does an ERV cost to operate monthly?
The ERV unit itself runs on a small motor — typically 20–80 watts depending on size and speed setting. That's less than $10 per month in electricity. The energy cost of ventilating with an ERV versus opening windows is where the real savings appear: an ERV recovers 70–80% of the cooling or heating energy from the exhaust air stream, so the net energy cost to condition fresh air is roughly 20–30% of what it would cost to condition the same volume of outdoor air directly. In Paradise's 100°F+ summers, that recovery makes mechanical ventilation far more efficient than any alternative that involves direct outdoor air contact.
Air Ventilation Technical Guide for Paradise Homes
ERV Performance in Hot-Dry Climates
Energy Recovery Ventilators work through a heat exchange core — typically a cross-flow or counterflow configuration using paper, polymer, or aluminum plates — that brings incoming and outgoing air streams into thermal contact without mixing them. In cooling mode (summer in Paradise), the 110°F incoming outdoor air passes adjacent to the 75°F exhaust air in the core, warming the exhaust slightly while cooling the incoming air substantially. A unit with 75% sensible effectiveness cools that 110°F incoming air to approximately 84°F before it enters the home — a 26°F pre-cooling that significantly reduces the burden on the air conditioner.
Las Vegas's hot-dry climate makes ERV performance superior to many other regions because the low humidity means the latent heat load (moisture removal) on the air conditioning system is already relatively low. The ERV's moisture transfer in summer — moving some humidity from outdoor air into the dryer exhaust stream — reduces, but doesn't eliminate, the latent load. The primary benefit in our climate is sensible heat recovery: pre-cooling incoming air in summer and pre-heating it in winter. In practice, a properly sized ERV paired with a high-MERV filtration system provides a complete mechanical ventilation solution for sealed Paradise homes without meaningful AC penalty.
Balancing Ventilation in Multi-Room Layouts
Balanced ventilation requires equal CFM supply and exhaust — but where you supply fresh air and where you exhaust stale air matters as much as the total volume. In Paradise's 1960s and 1970s homes, which often have linear floor plans with bedrooms at one end and living areas at the other, a common mistake is supplying fresh air only in the common area where the air handler is located while exhausting only from the bathroom. This pattern puts the bedroom occupants furthest from the fresh air supply. We design ventilation duct layouts that supply fresh air to sleeping areas — where people spend the most hours in a 24-hour cycle — and exhaust from kitchens and bathrooms where pollutant generation is highest. Getting the distribution right makes the same total CFM ventilation rate far more effective.
Paradise Neighborhood Ventilation Profile
Paradise's diverse housing stock creates meaningfully different ventilation starting points across neighborhoods.
- Paradise Palms (1960s mid-century residential) — These homes are among the leakiest in the area, with 10–15 ACH50 typical. They receive "accidental" infiltration ventilation through envelope gaps, but that infiltration is uncontrolled — hot, potentially contaminated outdoor air drawn through insulation gaps rather than filtered fresh air supply. The ventilation rate may accidentally exceed ASHRAE minimums, but the quality of the air supplied is poor. An ERV in a Paradise Palms home is less about providing adequate quantity and more about providing quality: controlled, filtered, partially conditioned fresh air that replaces random infiltration.
- Maryland Parkway and Tropicana corridor (1980s–1990s construction) — Moderate tightness. High vehicle traffic on adjacent roads means CO levels and fine particulate are elevated in outdoor air near these properties. ERV with activated carbon pre-filter on the intake strongly recommended for homes within 200 feet of these corridors. Exhaust fan adequacy often needs assessment in mid-rise apartment buildings here.
- Convention Center District and condo buildings (2000s–2010s construction) — Tightest construction in Paradise. Newer condos may have mechanical ventilation specified in the original design, but it may not be functioning adequately or may have been disabled. We assess existing ventilation equipment condition before recommending new installations.
My 1960s Paradise Palms home is drafty. Do I still need mechanical ventilation?
Drafty old homes do get ventilation air, but it's uncontrolled and of uncertain quality. In summer, the "fresh air" infiltrating through gaps in a Paradise Palms home has traveled over 110°F roof surfaces and through attic cavities before reaching occupied space. In winter and when winds come off busy corridors, it carries road dust and vehicle exhaust particulate. An ERV replaces random infiltration with controlled, filtered, partially conditioned fresh air at a predictable rate. It also gives you control: you can boost ventilation when cooking, reduce it during high outdoor pollution events, and monitor CO2 to ensure adequate air exchange without wasting conditioned air through unnecessary over-ventilation.
Is there any issue with locating ERV supply and exhaust vents close to the airport approach path?
The outdoor air intake for an ERV should be located away from known pollution sources per ASHRAE 62.2 guidelines — specifically, not near vehicle exhaust, plumbing vents, or known contamination points. Airport approach corridors do add jet exhaust particulate to outdoor air quality, which is why we always specify a MERV 13 or HEPA-level filter on the ERV's outdoor air intake for Paradise homes near the airport. This filtration step captures combustion particulate before it enters the ventilation airstream. The ERV's exhaust discharge should also be placed to avoid re-ingestion — typically on a different wall face from the intake, with adequate separation.
Air Ventilation Priorities for Paradise Homes
Paradise's combination of airport noise, urban heat, and dense commercial activity creates a sealed-home lifestyle that's rational for comfort but problematic for air quality without mechanical ventilation. The typical Paradise home runs its HVAC on recirculation all summer — which is efficient for cooling but means the same indoor air cycles through the system hundreds of times without meaningful fresh air exchange. CO2 builds, cooking odors persist, and any indoor pollutant source (off-gassing furniture, cooking byproducts, pool chemical infiltration from shared amenities) concentrates over time. An ERV with a MERV 13 pre-filter on the outdoor intake solves this directly: it exchanges stale indoor air for fresh outdoor air continuously, at a rate calibrated to ASHRAE 62.2 standards, while recovering 70–80% of the cooling energy from the exhaust stream. For Paradise residents who intend to stay long-term, this is the indoor air quality upgrade that makes sealed-home living genuinely comfortable and healthy rather than just tolerable.
