The HVAC Controls & Thermostats category covers the brains of the system—everything that tells equipment when and how to run. From simple non-programmable thermostats to connected smart stats, zoning panels, and OEM control boards, this section is built for technicians and advanced homeowners who want precise comfort, higher efficiency, and reliable operation on every job. Correct controls selection protects equipment, improves IAQ options, and reduces nuisance service calls throughout the year.
Here you’ll find programmable and Wi-Fi thermostats, communicating controls, zoning systems, defrost controls, fan centers, sequencers, relays, transformers, pressure switches, and sensor packages that support both traditional and modern HVAC platforms. We focus on field-proven controls that integrate cleanly with heat pumps, gas furnaces, air handlers, mini-splits, rooftop units, and light-commercial equipment, so you can handle replacements, upgrades, and retrofits with confidence.
When selecting HVAC controls and thermostats, go beyond matching stages. Confirm system type (heat pump vs conventional), fuel source, number of stages, common wire availability, zoning requirements, dehumidification or IAQ outputs, and accessory loads. For control boards, always verify OEM part numbers, wiring diagrams, and any required setup for blower profiles, fan delays, and safety circuits. Use the Compare tools on this page to review compatibility, features, display type, connectivity, and warranty.
Pro tip: Before upgrading controls, document existing thermostat wiring, equipment model and serial numbers, outdoor sensors, add-on humidifiers, dehumidification, and ventilation controls. Take clear photos of the old thermostat terminals and control board connections. Share those details and we can help you choose a matched thermostat, zoning kit, or control board package that installs smoothly and supports future add-ons.
