Wholesale HVAC equipment, parts & supplies
Gaston HVAC contractors can use Mar-Hy for OEM parts, controls and equipment supply. For a service call, retain the installed equipment model and component number so the repair request can be separated from any broader replacement discussion.
For contractors and trade purchasers. Serving Gaston from our Milwaukie, Oregon location.

Equipment planning & local resources
A motor, board or electrical component needs more identification than a general size or visual match. Include the manufacturer markings and equipment identity, with clear photographs where helpful. If a system replacement is also being considered, identify that as a separate request with the indoor combination and controls rather than attaching a new outdoor model to the repair list.
Equipment documents and supply resourcesUse Gaston’s official municipal website to locate the current department contact for site or project questions. Keep the property address and proposed equipment scope with that discussion; the equipment and parts request can be developed separately with Mar-Hy.
City of Gaston official resourcesOfficial application requirements and approvals come from the responsible jurisdiction. These resources are optional project references, not prerequisites for an equipment quote.
