Customer Feedback Honeywell Home Thermostat RTH221B1039

William Moscow

Our old, analog thermostat was lately the source of a gas furnace issue, and when the repairman arrived, he took one look at it and suggested that we replace it. Naturally, he offered to install the digital thermostat he had in his truck for us for $240, but we respectfully declined and chose this far less expensive alternative. This thermostat has performed admirably for us thus far. It doesn’t have any fancy features; it simply has a single software that runs continuously, and there is no phone access or anything of the kind. Nevertheless, it serves our purposes. We simply wanted a thermostat that we could set and forget about, and thus far, things are going well.

This thermostat was the ideal choice for us because it can be set for various temperatures throughout the day. We didn’t need anything fancy or with lights, and this was quite simple to install and use. There are a few excellent YouTube videos that show you how to install the until and configure it after. Additionally, I believe this device reads the real temperature in the home far more precisely than the old thermostat, which only provided the current temperature (which was always off by 4-6 degrees). You’ll be content with this if you’re not searching for something with incredible bells and whistles.

Malika Kazan

The thermostat is working well. Basic, straightforward, and effective. My only complaint is that less than a month after I bought it on Amazon, it is currently advertised as $3.00 cheaper than when I got it when it was sold at 33% off its original price.

The RTH221B Programmable Thermostat is Simple to Use, just as the box claims. The directions are straightforward, but you probably won’t even need them given how easy and straightforward the design is. Despite not being the most cutting-edge technology (it lacks Bluetooth), it can be programmed for the night, day, and daily away settings. Who needs their thermostat to be Bluetooth enabled? I advise you to set it and forget it. Additionally, the price is unbeatable; for $20, you simply can’t go wrong. Finally, Honeywell is the manufacturer. a reputable business with a lengthy history. I heartily endorse this product.
