Like most people, you probably don't think about your indoor air quality until you start to feel sick. But did you know that the air in your home can be up to five times more polluted than the air outside? You can look into the energy efficiency of an energy recovery ventilator (ERV) as an effective solution to better the air quality in your home.

What is an ERV?

What is an ERV

An energy recovery ventilator (ERV) is a device that recovers heat from exhaust air and uses it to preheat incoming fresh air. The benefits of an ERV include improved indoor air quality, reduced energy use, and reduced HVAC costs. An ERV can be used in homes that are not airtight and is no stranger to an open window, and it can be retrofitted to existing homes. ERVs can be installed by a homeowner, but it is advisable to consult with a contractor to ensure the correct size and type of ERV is selected.

How do I know if my home needs an energy recovery ventilator?

If you are considering an energy recovery ventilator (ERV) for your home, you may be wondering if your home needs one. You can consult air-conditioning engineers or qualified HVAC contractors to perform a home energy audit.

During a home energy audit, the contractor will inspect your home and determine where your most considerable energy losses are. The audit will also include a blower door test to measure the airtightness of your home. If your home is leaky, an ERV may be a good investment and bring a significant improvement and reduce energy costs.

Today’s homes that experience airstream leaks lose energy through cracks and openings in the walls, ceilings, and floors. This reduces the energy efficiency of your home and can drain energy savings. An ERV can help reduce the amount of energy lost through leaks, raise the energy standard of your home, and improve the indoor air quality in your home.

Are there benefits to an ERV besides money?


While you want to protect your HVAC unit and improve its durability, an ERV can do more than strengthen it and reduce your energy costs. One way to decide if an ERV is right for you is to consider the size of your home, the climate, and, most importantly, your family’s health and susceptibility to allergies. Contaminants, pollen, mould spores, and odours pose a higher risk if your air filtration system or HVAC unit isn’t working correctly.

An ERV can improve the air quality in your home by exchanging stale air for fresh air. This can help to reduce allergies and asthma symptoms, as well as improve your overall comfort. If you decide that an ERV is suitable for you, there are various models to choose from. It's essential to select a model compatible with your home's HVAC system. If you're not sure how to choose an ERV or have any other questions about them, please contact a professional for more advice.

There are other benefits to an ERV that help with health and comfort. An ERV can also help reduce moisture levels in your home, preventing the growth of mould and mildew. If you open your windows frequently, an ERV can help ensure that the air in your home is fresh and healthy. If you live in a very hot or cold climate, an ERV can help ensure that your home is comfortable year-round.

ERVs can be expensive to install, but they can save you money in the long run by reducing your energy consumption. Consult a professional if you're unsure if an energy recovery ventilator is suitable for you. A contractor or HVAC specialist can help you determine if an ERV is a right solution for your home.

Can I install an ERV myself?

ERV myself

If you are considering an energy recovery ventilator for your home, you may be wondering if you can install it yourself. The answer is yes, you can install an ERV yourself, but it is not always a simple process.

Before you begin, you will need to measure the size of your home’s ventilation system and determine the type of ERV you need. You can find this information in the owner’s manual or on the manufacturer’s website.

Once you have the right ERV, you will need to shut off the power to your home’s ventilation system and remove the old ventilation system. Wear gloves and safety goggles when working with the old ventilation system, as it may contain asbestos.

Next, you will need to install the new ventilation system. This may involve drilling holes in your home’s roof or walls, and you will need to be sure that the system is properly sealed to prevent leaks.

Once the ventilation system is installed, you will need to connect it to your home’s heating and cooling system. This may require the services of a professional HVAC technician. Once the system is installed, you will need to run a test to ensure it is working correctly. Be sure to follow the manufacturer’s instructions for testing the system.

We all want to live comfortably and breathe indoor air that doesn’t make us sick. We also want to prevent money losses to drafts, cracks, and lousy ventilation air. An ERV can build up the immunity of your home and avoid long-term damage to you, your house, and your loved ones in the long run.
