Honeywell

Honeywell was founded in 1886, and developed one of the first automatic thermostats ever. In 1953 Honeywell released their, now iconic, T-86 round thermostat. The style remains popular even today, and now Honeywell produces a larger line of HVAC related products including whole-home HEPA filtration and humidity regulation. Honeywell has proven itself as one of the leaders in thermostat technology, and Thomasson Enterprises offers many of their products.
