How does Erv work with air conditioning?

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.

Is an ERV necessary?

For starters, positive pressure systems generally rely on your HVAC system’s blower fan. An ERV doesn’t need to. While the ERV contains a fan that’s less powerful than your HVAC fan, it’s still powerful enough to ventilate your entire home. That might seen like a minor difference, but it’s huge.

Where should HRV vents be placed?

Rangehoods and fans should vent directly outside, not into your ceiling space, so this could be something worth changing, even if aren’t looking to have a ventilation system installed.

Does ERV filter air?

When an ERV flushes stale air out of your home, it also flushes out the pollutants contained in it. Additionally, the ERV filters the outside air, capturing contaminants such as pollen, dust, and other outdoor pollutants before they can get inside your house. This leads to improved indoor air quality.

Should ERV run continuously?

To maintain air quality set the ERV controls to the intermittent on off cycle. This continuous intermittent setting should be maintained all year round. If you have a party or are cooking food with odours you can turn the control to high for an hour or so.

Will an ERV remove humidity?

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.

Does an ERV replace an air conditioner?

Energy Recovery Ventilators Pre-Cool Fresh Air

How does an ERV do this? It isn’t because there’s an extra air conditioning system cooling down the incoming fresh air. Or ice, or cold water, or anything like that.

Where should ERV be placed?

The fresh air intake should be located where fresh air circulates, and away from driveways, range hood exhausts, furnace flue and laundry vents. The stale air from the home should come from a wall close to the kitchen, within one foot of the ceiling and 10 feet away from an oven.

How often does an ERV exchange the air?

about every six months

How often is it necessary to service an ERV? We recommend about every six months.

What is better HRV or ERV?

The best option between an HRV and an ERV depends on your climate and specific needs. If your house is too humid in winter (above 60% RH) then an HRV is the better choice, as it would surely get rid of excess humidity while an ERV would tend to keep it at a high level.

Can ERV reduce radon?

An ERV can reduce radon levels by adding fresh air and creating positive air pressure. Negative air pressure in lower levels of buildings produces a force that pulls soil gases inside the structure. If the negative air pressure can be reduced, the radon levels will also decrease.

What is an ERV radon?

An energy recovery ventilator (ERV) removes stale, polluted air from the home and replaces it with fresh outside air. National Radon Defense Dealers are trained to install an ERV to work with your existing heating and cooling systems.

Does air exchanger remove radon?

While an air exchanger typically isn’t installed as a radon mitigation system, a running air exchanger will reduce radon levels in the home*, because stale indoor air is replaced with fresh outdoor air.

Does HVAC help with radon?

This study shows that even the most standard ventilation provided by an HVAC system can reduce levels. The impact of radon is statistical and improvements can continue to be gained at levels below the current 4.0 pCi/l action level.

Is radon gas worse in summer or winter?

To answer that question, yes, radon levels in a home tend to be higher during the winter. And those higher levels of radon gas can lead to an increased chance of lung cancer. While indoor radon gas levels are generally higher during winter, sometimes the summer can have higher indoor radon levels.

Does running furnace fan reduce radon?

In many homes, blowing air in through an existing central furnace is quite practical. The use of an exhaust fan to pull air out of the house may decease the interior air pressure and draw more radon inside.

Does rain cause more radon?

Certain types of weather can have a greater impact on your home’s radon levels. Wind and rain storms create the largest variables of radon levels when testing for radon gas. Rainier days tend to result in noticeably higher radon levels. This is because rainy days are often coupled with lower barometric pressure.

What are symptoms of radon poisoning?

A persistent cough could be a sign that you have radon poisoning.

  • Persistent cough.
  • Hoarseness.
  • Wheezing.
  • Shortness of breath.
  • Coughing up blood.
  • Chest pain.
  • Frequent infections like bronchitis and pneumonia.
  • Loss of appetite.

What time of year is best to test for radon?

Ideal Conditions for Testing Your Home for Radon

The best time to test is during the fall or winter months since your home is closed up and windows are not kept open. As a result, radon levels will be the highest during these cold months.
