Can a fresh air ventilation system be installed in a renovated house and how to install it？

 Can a  Be Installed in a Renovated House?

Whether you’re planning to remodel your home or build from the ground up, you’ll need a quality mechanical ventilation system. A steady supply of fresh air can increase indoor air quality, improve occupant comfort and reduce energy consumption.

A typical balanced ventilation system consists of two fans and two duct systems for both fresh air supply and exhaust air removal. This approach aims to bring fresh air into living rooms and bedrooms, and exhaust polluted indoor air from places like bathrooms and kitchens.

Ductwork

The ductwork that distributes air throughout your home is an important part of your heating and cooling system. It ensures that your living spaces stay at the desired temperature, which is crucial for comfort and energy efficiency.

Ducts are usually made of a combination of materials, such as tin, steel, sheet metal, fiberglass, and flexible plastic. They’re designed to be insulated, balanced, and sealed for maximum air travel.

If you’re renovating  a house has fresh air ventilation system, ducts need to be inspected to make sure they’re in good shape and don’t block your new system. They may also need to be rerouted to minimize bends, which can reduce airflow and cause rooms to get too hot or too cold.

You should also be aware that ducts can be damaged during renovations, which means they need to be replaced or repaired. They can also be prone to clogging, which can result in reduced comfort and increased energy costs.

 Fans

Adding fans to your home can improve indoor air quality. They can also help reduce your energy costs because they draw fresh, cool air into your home through vents in the roof and gable walls.

Depending on the model of fan, these fans can change the home medics air purifier three to six times per hour. A properly sized fan should deliver 2 to 3 CFM (cubic feet of air per minute) for every square foot of living space.

In colder climates, ventilation can be balanced with heat recovery by placing the fresh and exhaust fans next to each other. That way, outgoing house air will precondition the incoming outdoor air, reducing humidity and increasing the effectiveness of the ventilation system.

These systems are becoming more popular in the new home construction industry. They can make homes more attractive to buyers, who are concerned about the environmental impact of their new home and its energy efficiency.

Filters

Fresh air ventilation systems recirculate air pulled from a home, reducing energy bills. They also help maintain consistent temperatures throughout the house.

In addition to circulating air, some systems incorporate filters that trap pollutants in the air. They typically use MERV-13 or HEPA filters, which are designed to capture particles that measure 2.5 microns in size.

These units are often incorporated into the ductwork, though they can be placed in a vented area to remove smoke and other contaminants. They work by applying a high voltage to air, then putting an electrical charge on particles.

Pleated filters, which pack more filtration material into a smaller space, are more effective than fiberglass or disposable filters. They typically cost a few dollars more and do a better job of trapping allergens, like pollen and pet dander.

Vents

There are many types of vents that can be installed in a renovated house. These include supply and return fresh air ventilation system that connect to a duct system that delivers fresh air into the rooms where occupants spend the most time.

Some of these ducts can also be used to bring outside air into the home. In these cases, you’ll need a damper to control the airflow volume.

Another option is a motorized shutoff damper that will seal the duct from outside air when the blower motor isn’t running.

These dampers can be an effective way to ensure that stale air doesn’t build up and become trapped in the house.

Supply ventilation systems use fans to bring in fresh air and release stale air through cracks and air leakage sites. This is an effective way to help reduce radon levels and improve indoor air quality.
