RenewAire EV Premium S

At a glance

• In its favour
• Plain fact
• Worth knowing
• Not stated by the maker

• In its favour: HVI-certified (HVI 2004797)Its airflow and efficiency were tested to the Home Ventilating Institute’s standard.
• Plain fact: 119 cfm at 0.4 in., 112 cfm at 0.5 in. of duct pressureCertified fresh air delivered, at HVI’s headline rating point and at the higher pressure many real ducts run at.
• In its favour: RenewAire’s own CO₂ control (CO2-W or CO2-D) is documented for the EV PremiumIt runs the unit on high above its trip point, which can be set from 500 to 1,500 ppm. Set it to 750.
• In its favour: Humidity control documented
• Plain fact: How it handles frost in very cold weatherNo defrost cycle. The brochure says there is no need for frost protection. RenewAire's frost policy says its plate cores work without condensing or frosting when it is warmer than -10°F outside and indoor humidity is below 40%. For colder or more humid conditions RenewAire points to standard defrost methods, and it sells an optional RH series electric duct heater (1-4 kW for this model, for indoor ductwork only).

Certifications

• HVI certified

  HVI 2004797

  The Home Ventilating Institute tested its airflow and heat recovery. The certified numbers on this page come from its directory. Find HVI 2004797 in HVI’s directory

• ENERGY STAR (Canada)

  Not on the list

  Not on Natural Resources Canada’s ENERGY STAR list when we checked. ENERGY STAR certifies HRVs and ERVs only in Canada, so a unit sold in the U.S. may never have been submitted; that isn’t a sign it’s less efficient. Its HVI numbers show its heat recovery and fan power. NRCan’s ENERGY STAR list (checked October 19, 2026)

Would it cover your home?

Tell it who sleeps in each bedroom. It’s checked against the 800 ppm goal the same way the app checks a unit an installer quotes.

Certified airflow

How much fresh air it delivers as the ducts push back. More duct pressure, less air: that’s why the installer’s duct design matters as much as the unit.

Lowest steady airflow (maker)

30 cfm

Highest airflow (maker)

130 cfm

Heat and moisture recovery

Sensible recovery (SRE) is the share of heat kept in winter, after the fan’s own heat is taken out; total recovery (TRE) counts moisture too, in summer.

• Plain fact: Keeps 66–74% of the heat at 32°FAcross the airflows HVI tested.
• Not stated by the maker: No very-cold (−13°F) test in the HVI directory
• Plain fact: Total recovery in summer: 60% at 95°FThe share of heat and moisture kept out on a hot, humid day.

HRV or ERV: which fits your home?

Turning up on CO₂

A CO₂ control can switch it to a higher speed when the bedroom needs air, then back. HouseExhale’s setting: up at 750 ppm, back at 650, never above 800.

• In its favour: RenewAire’s own CO₂ control (CO2-W or CO2-D) is documented for the EV PremiumIt runs the unit on high above its trip point, which can be set from 500 to 1,500 ppm. Set it to 750.

What RenewAire documents

• In its favour: Its own CO₂ control: CO2-W (wall) or CO2-D (duct)A relay that runs the unit on high above its trip point. Documented for the EV90, EV130, EV200, EV Premium and EV Premium+.
• In its favour: The trip point can be set from 500 to 1,500 ppmSo 750 is fine. The gap before it switches back can be 25 to 200 ppm. The factory setting isn’t published: check it.
• Plain fact: EV Premium: a contact between 24VAC and HIGH runs it on highWhen CO₂ drops it goes back to normal, or turns off if it was installed that way. Ask for normal.
• Worth knowing: EV90 and EV130: unpowered controls onlyNever connect power to their control terminals. On these the contact may switch the unit on and off, not up: ask.

Four ways to make it turn up by itself

• Its maker’s CO₂ controlMade for it

  RenewAire’s CO2-W or CO2-D, set to switch at 750 ppm, with the unit staying on its normal speed below that.

• A CO₂ control on its high-speed inputAsk your installer

  Its HIGH terminal takes an external control; RenewAire’s own sensor is the documented one.

• A night scheduleAsk your installer

  A timer on the HIGH input, or its touchscreen control on the EV Premium+.

• Your monitor and a smart-home relayAsk your maker first

  A dry-contact relay on the same HIGH input. Not documented by RenewAire.

Installing it

The maker’s facts an installer plans around. Your installer confirms them for your home.

Power

120 V, 60 Hz, single phase. Manual: 3.0 A for S, M and L. Submittal: 53 W for the whole unit, 0.85 A per motor, 15 A circuit. Comes with a 34 in plug-in cord and needs a grounded 120 V outlet nearby; the EV Premium SH version is hard-wired instead.

Duct connections

Four duct connections (outdoor air, exhaust, return, supply). The four duct connectors ship loose and the installer fits them; they take 6 in or 8 in round duct. Every duct run must be at least 40 in long. The manual and drawing don't say in words whether the ports are on the top or side.Scope: manual covers EV Premium S, M, L and their hard-wired H versions

Size

22 1/2 in long x 9 1/2 in wide x 23 3/4 in high (product page); the brochure and drawing give the width as 9 5/8 in (see notes). With hanging bracket: 25 1/2 in and 9 5/8 in overall.

Weight

32 lb (38 lb in its shipping carton, 30 x 22 x 15 in)

Mounting

Any position, as long as there is room to reach the controls and open the door at least 90 degrees. Horizontal is preferred so the hinged door swings down. Hangs from a bracket fixed across two wall studs (or anchored into concrete); the brochure lists ceiling or wall brackets.Scope: whole EV Premium series

Drain line

No drain is mentioned in the manual or submittal. RenewAire's brochure says the core has "No need for frost protection or condensate pans."Scope: brochure covers the whole EV Premium series

Cold weather

No defrost cycle. The brochure says there is no need for frost protection. RenewAire's frost policy says its plate cores work without condensing or frosting when it is warmer than -10°F outside and indoor humidity is below 40%. For colder or more humid conditions RenewAire points to standard defrost methods, and it sells an optional RH series electric duct heater (1-4 kW for this model, for indoor ductwork only).

Rebates

Federal tax credits ended for work after 2025. Some states and utilities still pay toward an HRV or ERV: rebates by state.

Filters

• Type: One spun-polyester filter in the outdoor air and one in the return air (the manual calls them mesh-type anti-microbial filters). An optional pleated MERV 13 for the outdoor air side ships loose.
• MERV: MERV 8 standard; MERV 13 optional (outdoor air side only)
• Size: 7 1/2 x 10 1/2 x 1 in (two)
• How often: Manual: replace both filters every 3 months, or more often if needed; don't clean them. Product page: inspect every 3 months and replace as needed.

Warranty

• Core: 10-year structural and performance warranty on the plate core. The warranty statement says that in years 3 to 10 a defective core is repaired or replaced at no charge, labor not included.
• Parts: Five years on residential products. The statement says five years from the date of manufacture, with defective parts repaired or replaced at RenewAire's option.
• Motor: No separate motor warranty is stated.
• Labor: Not covered ("THIS WARRANTY DOES NOT INCLUDE LABOR"); the installer's own warranty may cover it.
• Conditions: The unit must be installed and run per RenewAire's instructions and maintained. Keep proof of the installation date; without it, coverage starts 30 days after manufacture. Online registration is not required. Report defects to a RenewAire dealer or contractor. Filters are excluded.

Scope: the warranty statement covers RenewAire ventilation equipment generally; the 10-year and 5-year terms are on the EV Premium S page

Sound

RenewAire publishes sound power (how much sound the unit gives off), not a sones rating, from its own tests (AHRI 230/260, ISO 9614). Cabinet: 46 dBA at 39 CFM, 55 dBA at 125 CFM, 56 dBA at 172 CFM. At a room supply outlet fed by 5 ft of insulated flex duct: 43, 54 and 59 dBA at 40, 127 and 173 CFM. At a room return fed by 5 ft of flex: 50, 59 and 62 dBA at 40, 127 and 172 CFM. With 1 m of hard duct the room supply figures are much higher (73-76 dBA). These are not loudness at a set distance.

Nothing we checked for is missing.

Where the maker’s own documents disagree

• Width: the product page says 9 1/2 in wide, but the EV Premium brochure (07/26) and the NOV23 drawing say 9 5/8 in.
• Power conflict inside the submittal: the electrical table gives 53 W for the whole unit, but the performance table shows 137 W at maximum speed at 0.10 in. w.g. The manual gives 3.0 A.
