Contact Heat and Air Controls

Our team works from the United States. Email us at support@heatandaircontrols.pro.

We answer on business days. Because we check messages in order, which can take a day during busy periods, include the details below so we can reply at once.

What to include

• Your system. Heat only, residential HVAC, or radiant floor heating.
• The voltage and the thermostat or control model, if you know it.
• Your wiring, including whether you have a C-wire.
• Your order number for shipping or return questions.

If you can, attach a photo of the old wiring and the wiring diagram label.
