RO systems typically have a pre-filter, a reverse osmosis membrane, and a post-filter. The pre-filter takes out larger particles like sediment and rust, while the reverse osmosis membrane takes out smaller particles and dissolved solids. The post-filter gets rid of any remaining impurities and improves the taste and smell of the water.


RO systems are often used to clean drinking water for your home. They can get rid of a wide range of impurities, including bacteria, viruses, and heavy metals, as well as dissolved solids like salt and minerals.

  • 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.



RO systems remove dissolved solids that other types of filtration systems, such as activated carbon filters, can't. They are also very efficient, with some systems able to remove up to 99% of impurities. 



Maintaining your reverse osmosis is easy when you follow a few easy steps from the manufacturer recommendations. Some of the filters should be changed annually and some every 3 to 5 years depending on your water usage. We offer reverse osmosis system maintenance to homes in Kitchener-Waterloo, Cambridge, Guelph, Woodstock and surrounding areas.

Top Notch Customer Service

Eric is amazing! He arrived right at the beginning of our appt window and was friendly and professional from the get go! He got to work quickly and didn't even mind my barrage of questions! The customer service from Aire One was top notch as well. It was easy to book (and reschedule) my appt both via phone and online chat. I received an update email the day before, narrowing my service window to a 2 hour time slot....nice! I also received another email when Eric was on his way. How refreshing to have such a smooth experience:)
