The World's Most Trusted HVAC Controls & Thermostats
Brand history, product range & what we stock
Honeywell has been the world's most recognized name in HVAC controls since 1906, producing the thermostats, gas valves, ignition controls, and sensors that regulate millions of heating and cooling systems globally. The HVAC controls division, now operating as Resideo Technologies under the Honeywell Home brand, maintains the same engineering standards and product quality established over more than a century of controls innovation. Honeywell products are specified by HVAC OEMs worldwide as the default control components in their equipment.
National HVAC Parts stocks 8,500+ genuine Honeywell HVAC control parts including gas valves, hot surface igniters, thermocouples, thermostats, pressure switches, relays, zone controls, and damper actuators. Our Honeywell inventory covers both the standard Honeywell Home product line and the Resideo professional products catalog, including the high-volume VR8200, VR8300, SV9502, and SV9601 gas valve families, as well as the complete TH and CT thermostat lines.

Common questions about Honeywell OEM replacement parts
Resideo Technologies is the company that separated from Honeywell International in 2018 to take over the home and building controls business. Honeywell Home is Resideo's brand name for residential products. The products are the same proven Honeywell controls — only the corporate parent changed. OEM part numbers remain identical.
The most frequently replaced Honeywell gas valves are the VR8200A/C/H series (standing pilot), VR8300 series (electronic ignition), SV9502/SV9602 SmartValve series, and the SV9500/SV9600 SmartValve II series. Search by your furnace model or existing gas valve part number to find the correct replacement.
Yes. We stock Honeywell commercial controls including the W7100 and W7220 economizer controls, T7300 commercial thermostats, W973 and W7459 enthalpy controls, and a range of Honeywell commercial damper actuators, VAV controllers, and pneumatic-to-electric transducers.
White-Rodgers (now Emerson) and Honeywell are the two dominant gas valve manufacturers, and in some cases cross-references exist for equivalent valve sizes and specifications. However, gas valves are safety-critical components and should only be substituted with exact OEM-specified replacements. Contact our team to confirm compatibility.
