Old homes with broken windows or that develop cracks over time might enable natural ventilation, but it compromises the temperature, humidity and energy costs. You need a home recovery ventilation system to keep the people living inside your home healthy. There are certain benefits of home ventilation systems:

  • Welcomes healthy and fresh air inside your home.

  • Removes the pollutants and irritants like carbon monoxide, volatile organic compounds present in your home, dust, mould and pet dander away from your home.

  • A cost-effective way of reducing energy consumption.

  • Maintain a constant temperature in your home.

To get the best advice on which ventilator to install, get in touch with our experienced professionals at Aire One Heating and Cooling.


Residential ventilation may occur naturally or mechanically, but specific mechanical systems must maintain indoor air quality levels in airtight houses. There are broadly two types of ventilators available for your home.

Heat Recovery Ventilators (HRV) transfer heat to condition incoming air. It is ideal for northern climates with a more extended cold-weather season, where excess moisture can be a problem.


Energy Recovery Ventilators (ERV) transfers both heat and moisture. It is suitable for both warmer and cooler climates.

  • How often should I service my boiler?
    A minimum of once a year is recommended. Heating systems come on an average of 3-8 times per hour during the heating season, these numbers can change dramatically in different style of homes and with different thermostats, but this is a rule of thumb in our industry. There is a lot of wear and tear on the appliance and setting can go out of calibration. Also, it is a requirement by most manufacturers and home insurance companies.
  • Can I add new zones to my existing boiler heating system?
    It depends if the btu output of the radiators has reached the maximum btu output the boiler can support. Having a professional to come out and calculate is your best bet.
  • How will I know if the boiler I select will work properly for my home?
    Each room will have a radiator and every radiator has a specific btu output . We calculate the total of the radiator btu outputs, match that with a heat loss/heat gain calculation for the home and that is how we size a boiler system for your home.
  • How does a boiler work to heat my home?
    A boiler is a device that heats water and then distributes the hot water throughout your home to warm the indoor air. There are two main types of boilers: hot water boilers and steam boilers. Hot water boilers heat water to a temperature of about 82 C. The hot water is then circulated through a system of pipes and radiators throughout the home. The radiators give off heat to the surrounding air, which warms the home. Steam boilers heat water to a temperature of about 100 C, which is the boiling point of water. The steam is then distributed through a system of pipes and radiators throughout the home. The steam condenses back to water on the radiators, which gives off heat to the surrounding air, warming the home. In both hot water and steam boilers, the water in the pipes cools and returns to the boiler after heating the interior spaces. The water is then reheated and recirculated throughout the home. Some boiler models also double as a water heater, eliminating the need for a separate water heater unit. The efficiency of a boiler is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. The AFUE rating is a percentage of the fuel that’s used to heat the water that heats the home. The higher the AFUE rating, the more efficient the boiler. Boilers with medium levels of efficiency have ratings of 90 to 93 per cent.
  • What is the average lifespan of a residential boiler?
    The typical residential boiler can last between 15 and 20 years. You can find the year your boiler was manufactured by checking the unit’s rating plate. You can also call the manufacturer and give them the unit’s serial number to find out how old your boiler is. If your boiler unit is more than 15 years old, you should consider replacing it with a new boiler, high-efficiency gas furnace or heat pump.
  • Are there any government rebates available for my boiler upgrade?
    Unfortunately, Ontario homeowners in the Tri-Cities area wanting to invest in a new boiler system for their homes aren’t eligible for rebates under the Home Efficiency Rebate Plus (HER+) program. Heat pumps are the only home heating system covered under HER+, whereby homeowners can get more than $10,000 in rebates on a heat pump installation. This program combines the Enbridge Gas rebate program and the Canada Greener Homes Grant.



Heat Recovery Ventilators (HRV) improve indoor air quality by blowing out the old air and bringing fresh air inside your home in an energy-efficient way. It does not require any external furnace or air conditioning for it to function. An HRV functions in the following way:

  • The old stale air from your house is made to pass through the HRV. The previously stored heat warms the plates of the heat exchanger.

  • As soon as the plates get heated up, the HRV introduces clean and fresh outdoor air inside your home.

  • The process is repeated cyclically, ensuring the pollutants get evacuated from your home and you are provided with fresh air all the time.



Energy Recovery Ventilators (ERV) transfer heat/cooling energy and water vapour to provide healthy air. It improves energy efficiency and increases cost savings while maintaining a consistent indoor temperature and circulating fresh air throughout your home. An ERV works on a similar principle as that of HRV. Still, it includes an added step of transferring moisture from the outgoing air into the incoming clean, fresh air to maintain the humidity in your home at a constant level. Our energy recovery ventilators also remove excess humidity to enhance comfort and efficiency.
