The Aprilaire Model 1770 dehumidifier works throughout your entire home. It removes up to 300% more water per kilowatt hour than leading portable dehumidifiers. The Aprilaire 1750 and 1770 models differ only in capacity—the 1770 has a total removal capacity of up to 150 pints per day. The Model 1770 also features truly automatic control, so there is never a need to manually control the dehumidifier—just set it once and forget it. The best choice for healthy, comfortable air is the 1770 Whole House Dehumidifier installed in your new or existing heating and cooling system. The benefits and results speak for themselves.

What I like about the Aprilaire 1170:

The Aprilaire 1770 is a ductable dehumidifier that has all the same features as the popular 1750 model. What sets it apart, is an impressive AHAM  removal capacity of  150 pints per day. The color has been changed from beige to light blue, and it has an LED status indicator that lets you know when the unit is running, sampling, defrosting or in need of service. This dehumidifier is built to integrate into your homes’ HVAC system and requires some installation with ducting work. The dehumidifier comes with built in duct collars to easily attach to your HVAC system.

It has a built in air cycling feature which will trigger the blower in your HVAC system to turn on. This feature is helpful to help balance the humidity of the air throughout the entire home. Lastly, this unit has something I have never seen on any other dehumidifier, it has the ability to pull in air from the outside using its patented built in ventilation feature. The dehumidifier will dehumidify the incoming air from outside as it enters.

Aprilaire offers an accessory called the Living Space Control which can be used with this dehumidifier to monitor and control moisture in a specific location. This accessory looks like a thermostat on a normal HVAC.

What I do not like about the Aprilaire 1770:

As with all Aprilaire dehumidifiers, I wish it had a hygrometer on board rather than just a 15 position turn knob. This model does not come with wheels. It can be converted into a free standing unit in the event you need to dehumidify an isolated area.

In summary, if I was going to attach a dehumidifier to my HVAC system, I would purchase this one. Could I do the installation myself? Probably, but I would also consider having an HVAC professional come out and hook it up for me.
