(Based on 34 reviews)

Reviews show a mixed experience: some long-time trade customers mention helpful, thorough counter support and timely ordering. Others report frustration with contractor-only purchasing, tone at the counter, and warranty handling expectations. Positive notes cite on-schedule deliveries and staff going out of their way on occasion. Feedback suggests experiences vary by visit and situation.

Was denied a purchase because I wasn't a contractor.

Rude as hell… If I’m ever in the area again, I’ll make sure to steer clear of this place. Smh

Frequently Asked Questions

This location operates as a wholesale distributor and generally sells to licensed contractors. Some items may require account status or proof of trade. If you are not a contractor, consider contacting a local HVAC company to source the needed parts. Policies can vary, so calling ahead is recommended.

Contractors can use the official website’s store page to view local inventory after signing in to their account. You can also call the branch counter for part lookups. Availability may change during the day, so confirm pickup timing before arriving.

Bring the model and serial numbers of the equipment, clear photos of the existing part, and any manufacturer part numbers. This helps the counter quickly identify compatible replacements and confirm what’s in stock. If a special order is needed, they can advise on lead times.

Warranty handling typically follows manufacturer and distributor policies and may require documentation from a licensed contractor. Processing can vary by brand and part type. It’s best to call ahead with serial numbers and purchase details to understand next steps.
