Here's what one customer had to say ...

Ontario Soft Water (OSW) just finished installing a furnace/air conditioner/humidifier, water heater and water conditioner in my house. Excellent job. I couldn't have asked for it to go any better. this was not a trivial installation job. The new piping and ductwork was done meticulously. After reviewing many HVAC (Heating/Ventilation/Air-Conditioning) web sites, I understood that it's not the equipment that defines the success of an installation, it's the skill of the installers.
