Extended Promotion

Hey customer!

Due to high demand, we've extended our Humidifier promo to the end of January.  Do you have one of those dingy, old, unhygienic, unsanitary drum humidifiers? If you do, we have a December special for you. For a limited time, we are offering a 30% discount on the replacement of your old humidifier.  We will replace your old humidifier with a new Cascade humidifier for a special price of $420 from our regular retail price of $600. That is a $180 savings!

If you’re interested please don’t hesitate to call us and book an appointment at your earliest convenience.

Some restrictions apply: Promotion is only available to existing Humidifier owners and does not include the cost of a Condensate Pump if necessary​​​​​

Happy New Year to all our Customers!

Now that the holidays have passed and the dust has settled from all the festive joy, we would like to remind all our customers to first check and then clean or replace their air filters in their Furnaces. This is a time during the season when we experience an uptick in service calls due to neglected air filter.  To avoid the hassle and pain of an unnecessary and expensive service call, we are asking everyone to take a minute and look at their air filters. Pictured below (L) is a dirty filter, and (R) is a clean one.

remember to take care of your filter
