Yes. Refurbished ecobee3 thermostats meet all of the same performance expectations and requirements as new ones – from the inside out. If an ecobee3 cannot meet our exactly quality standards, for whatever reason, we won’t sell it. Our standards don’t change – only the price does.
Our thermostats are long lasting, durable products and we believe that good technology shouldn’t go to waste. So, we decided to take the time to refurbish these devices and offer them at a great price to help more people experience life with ecobee3. We believe it’s the right thing to do. For both our customers and our environment. Happy people. Happy planet.
Here’s how we ensure top-notch quality: Returned ecobee3 thermostats are first inspected and tested by our manufacturing engineers to identify any damage or component issues. Any issues are repaired with new parts. The thermostat then goes through the same quality assurance test as a new ecobee3. By the end of the process, there’s no difference between a refurbished ecobee3 and a new one.
Absolutely. Every refurbished ecobee3 is built to last and comes backed by a solid one-year warranty. In short: if your refurbished ecobee3 doesn’t work the way you want it to, we’ll do everything we can fix the issue. If we can’t fix it – we’ll replace it.
We want you to love ecobee as much as we do, so we offer a 30-day money back guarantee. If you are not totally satisfied with your refurbished ecobee3 – for any reason – simply return it to us in its original condition within 30 days and we’ll happily give you a full refund of the purchase price. No questions asked. Shipping and handling charges are non-refundable.
