Heat Pump and Heating in Miami

About Johnstone Supply
Google's own description of this location is direct about what it is: a wholesale chain providing a large selection of HVAC and refrigeration parts, supplies, and equipment. Johnstone Supply, on SW 131st Ave in Miami, carries heating equipment supplier and air conditioning system supplier as its two listed classifications, both pointing toward parts and equipment distribution rather than a company that repairs a home cooling system directly. That distinction matters for a Miami-Dade homeowner: this location functions more as a resource for the contractors who do the actual repair or installation work than as a first call when an air conditioner stops running.
Hours run Monday through Friday from 7:30 AM to 5 PM, with both Saturday and Sunday closed, a schedule aligned with a business-to-business supply operation rather than one built around weekend or emergency residential calls. The address sits within reach of Miami Beach, Coral Gables, and Hialeah, the neighboring communities listed alongside the immediate Miami location, though the business itself is a supply point rather than a service area in the traditional sense.
A licensed HVAC contractor working anywhere in that broader area could plausibly source parts, refrigerant equipment, or replacement components here rather than special-ordering them elsewhere. For a homeowner facing a system failure during Miami's long cooling season or after a storm has interrupted power and strained equipment on restart, the more useful move is contacting a residential air conditioning contractor directly, one who might then turn to a supplier like this one for the parts needed to complete the job.
Calling (786) 249-4828 during posted weekday hours is how to check current inventory and find out whether individual customers, not just contractor accounts, are welcome to purchase on site.

Frequently asked questions about Johnstone Supply
Does Johnstone Supply repair home air conditioning systems?
No, the business describes itself as a wholesale chain providing HVAC and refrigeration parts, supplies, and equipment, and its classifications list heating equipment supplier and air conditioning system supplier rather than a repair or contracting service. Homeowners needing a repair visit should contact a licensed HVAC contractor instead.
What are the hours at the Johnstone Supply location in Miami?
This location is open Monday through Friday from 7:30 AM to 5 PM and closed on both Saturday and Sunday. That weekday-only schedule fits a supply business serving contractor accounts rather than a residential service with weekend hours.
Can individual homeowners buy parts from Johnstone Supply, or is it for contractors only?
The public listing does not specify whether walk-in individual customers are accommodated alongside contractor accounts, so anyone interested should call (786) 249-4828 during posted hours to ask directly. Its description as a wholesale chain suggests contractor accounts are the primary customer base.
Why would a Miami-Dade contractor use a supplier like Johnstone Supply?
As a wholesale supplier of HVAC and refrigeration parts, supplies, and equipment, this type of location lets a contractor source replacement components quickly rather than waiting on a special order, which matters when a Miami-Dade household is without cooling during a long, hot stretch of the year. The Miami location serves that role for contractors working near Miami Beach, Coral Gables, and Hialeah.
