Commercial HVAC maintenance for Miami businesses
A rooftop unit that fails on a Saturday in August costs a business far more than a scheduled visit. A service agreement puts filters, belts, coils and drains on a calendar so the failures happen less and on your terms.

Commercial HVAC maintenance in Miami is a service agreement that schedules visits for rooftop units and split systems, usually quarterly, covering filter changes, belt checks, coil cleaning, drain and condensate pan service, electrical tests and a refrigerant check. Our Medley head office and SW 117th Ave service office keep the schedule and send the manager a written summary after each visit.
The job
What a commercial agreement covers that a one-off visit doesn't
Commercial systems run long hours under heavy load, often on roofs no one looks at between failures. Filters load quickly, belts stretch and glaze, condenser coils pack with debris, and condensate drains clog and back up into ceilings. Each is predictable, and each is cheap to deal with on a schedule.
An agreement also gives the building a record: the same readings taken visit after visit, so a failing compressor or a slow refrigerant leak shows up as a trend long before it shuts the business down.

What we see on this job
Quarterly service agreements
Most Miami commercial sites do best with quarterly visits because of how hard the equipment runs. Each visit follows the same checklist: filters, belts, coils, drains, electrical connections, amp draws, refrigerant pressures and controls. Two of the four visits include a full condenser coil cleaning ahead of and after the hottest months. The manager gets a written summary of each unit's condition and any repairs we recommend, priced separately and approved before any work is done, so there are no surprises on the invoice.
Filter and belt programs
Filters and belts are the maintenance items that make the most difference and are most often skipped. We record each unit's filter sizes and belt numbers, bring the right ones to every visit, and change them on a schedule suited to the site: a restaurant or a dusty warehouse loads filters faster than an office. Belts are checked for tension, wear and alignment and replaced before they slip or snap and stop the blower in the middle of a busy day.
Multi-site accounts
Businesses with several locations across Miami-Dade can put every site on one agreement with one schedule and consistent reporting. Each location gets its own unit list, access notes and contact, and the visits are routed so technicians cover nearby sites together. Repairs are quoted per site, and invoices can be matched to each location's purchase order or cost center. Emergency calls at any site go through the same 24/7 dispatch line as everything else, and the technician arrives with that site's unit list and access notes.
Local conditions
Timing visits around Miami's rainy season
Miami's rainfall climbs from about 5 inches in May to nearly 10 inches in June and stays high through September, which is when rooftop drains, condensate pans and curb seals are tested hardest. A spring visit that clears drains, checks pans and inspects curbs before June is the one that most often prevents a ceiling leak in a store or restaurant during the wet months.
