ERVs are systems designed to be connected to the ducts that are part of your HVAC system. By way of two fans, ERVs draw clean, fresh air into a home or office and remove stale air. UltimateAir’s systems feature a patented heat exchanger which facilitates the transference of heat and moisture between the air streams.
How does a ERV work?
An ERV Captures Energy From Exhaust An ERV works by capturing the air that’s exhausted from your home and using that air to create the energy needed to ventilate your house. The ERV also treats the air the device ventilates into your house, instead of letting in humid Georgia air like a fan would.
Is an ERV system worth it?
In sum, an ERV offers more consistent ventilation and better control over how much fresh air you’re getting. It’s also easier on your utility bills.
Which is better HRV or ERV?
An HRV is a better choice if you often have an overly humid house during winter, while an ERV is superior if your house is too dry. An HRV will tend to increase humidity during the summer, while an ERV will help control it. It is best to leave the job of making the choice to our indoor air quality professionals.
What is a residential ERV?
Lifebreath Residential and commercial Energy Recovery Ventilators (ERVs) are the best choice for ventilating your home or workplace. These units are designed to provide fresh air into the building while exhausting an equal amount of stale air to the outside.
What are the benefits of an ERV?
Benefits of ERVs Improved Indoor Air Quality. When an ERV flushes stale air out of your home, it also flushes out the pollutants contained in it. Better HVAC Efficiency. Improved Moisture Control. Improved Odor Control. Easy Maintenance. Controlled Ventilation. Increased Comfort Levels.
Does ERV control humidity?
ERV ventilation solutions offer balance, humidity control and comfort. Did you know that nearly 90% of the energy used to cool a home is required to remove humidity? While similar to HRVs, ERVs also remove humidity from the air before it is brought into the home – greatly reducing cooling costs.
Do you need a humidifier with an ERV?
In winter, monitor the humidity level in your home. If humidity drops below 35% you should turn up your humidifier or set your ERV to a lower setting. When the air outside is extremely cold, you can expect to have condensation on the windows.
Does ERV save money?
ERV systems save energy by reducing the need to cool or heat outside air. Although energy consumption from fans can rise after an ERV system installation, the savings in heating and cooling energy generally far outweigh any increases.
How long does an ERV last?
Most ERVs are designed to last 20 years or more.
When should you use an ERV?
If your heating tends to dry the air (electric baseboard heaters, for example), an ERV is preferable. When Your Home Was Built: ERVs are recommended for homes built prior to the 1970s that usually have drier indoor air, because their construction allows humidity to escape outdoors.
How do I pick an ERV?
How To Choose An Energy Recovery Ventilator Energy transfer rating– what percentage of outbound energy is transferred to inbound air? Cost-of-Ownership– how much does it cost per year to operate? Moisture transfer efficiency– does the system effectively manage moisture and not just heat?.
How many ERVs do I need?
HRVs/ERVs are typically sized to ventilate the whole house at a minimum of . 35 air changes per hour. To calculate minimum CFM requirements, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by .
How much does an HRV cost?
Price: The starting MSRP of the 2022 Honda HR-V is $21,870. The top EX-L AWD model starts at $28,170. The Honda HR-V is an exceedingly practical choice in subcompact SUVs. It has one of the roomiest interiors in its class, it’s good on gas, and it has a solid record of good reliability and resale value.
Is an HRV system worth it?
Are HRV’s worth it? Although there are many answers to that question, perhaps the best answer is: Yes, it can improve your quality of life.
Do I need an HRV system?

Do I need a humidifier if I have an HRV?
Air humidification can represent an essential addition to an HRV unit. Controlling relative humidity and keeping it at around 50% is in fact fundamental for ensuring the health and comfort of the people who occupy indoor spaces.
Should I run my ERV in the summer?
In summer, the heat and humidity are outside and your ERV will keep most of it from getting inside with your ventilation air. However, if you have air conditioning and the indoor air is cooler and dryer than the outside air, it is generally a good idea to run your ERV intermittently throughout the day.
What should I set my ERV?
A typical ERV, though, can move 100 to 200 cubic feet per minute (cfm) of air. A typical house needs maybe 50 cfm (depending on which ventilation standard you go by). What many designers do is set the ERV to run intermittently, say 20 minutes out of each hour, to meet the ventilation needs of the house.
