Commercial HVAC
Commercial HVAC & AC Services in Miami
Zaldak Maintenance keeps commercial air conditioning and HVAC systems running for condos, offices, retail, restaurants and multifamily buildings across Miami-Dade and South Broward — repairs, scheduled preventive maintenance and 24/7 emergency response, performed by our own licensed in-house technicians rather than subcontractors.
Why commercial AC in Miami needs a plan, not a phone number
In South Florida, cooling isn't a comfort feature — it's uptime. A rooftop unit that fails on a July afternoon empties a restaurant, sends office tenants home and puts a condo board on the phone. The cost of a breakdown is almost never the repair itself; it's the hours of downtime, the emergency premium and the damage that spreads while you wait.
That's why we treat commercial HVAC as a system to be managed, not a series of emergencies to react to. Scheduled inspections catch failing capacitors, dirty coils and refrigerant drift before they become outages, and a documented service history makes every future repair faster and cheaper.
What we handle
- Rooftop package units, split systems, mini-splits and VRF for commercial spaces
- Diagnostics and repair — compressors, capacitors, contactors, fan motors, thermostats and controls
- Preventive maintenance: coil cleaning, refrigerant checks, condensate line clearing, belt and filter programs
- Air handlers, ductwork sealing and airflow balancing
- Condo and multifamily common-area systems, hallway and amenity cooling
- Restaurant and retail cooling where humidity and heat load run high
- 24/7 emergency AC repair with priority dispatch for plan members
How it works for property managers
One call opens a work order. We confirm scope, send a licensed technician, quote anything beyond the service visit before we touch it, and close the ticket with photos and notes you can forward to a board or an owner. For portfolios, we keep an asset list per building — make, model, age, service history — so you're never starting from zero.

FAQ
Questions we get asked
Is a broken AC considered an emergency in Florida?
For a commercial property, usually yes. When indoor temperatures climb in Miami heat, occupants, tenants, food storage and electronics are all at risk, and health-code and lease obligations can be triggered within hours. We treat a no-cooling call in an occupied building as an emergency and dispatch 24/7.
How much does commercial AC repair cost in Miami?
It depends on the system and the failure — a capacitor or contactor is a small job, a compressor or refrigerant leak is a larger one. We diagnose first and quote the repair before any work starts, so you approve a known number. Buildings on a maintenance plan pay less over time because small issues are caught before they become big ones.
What is the '$5,000 rule' for air conditioning?
It's a common rule of thumb: multiply the unit's age in years by the repair estimate. If the result is over roughly $5,000, replacement is usually the better investment. We'll tell you honestly which side of that line your equipment is on.
How often should commercial HVAC be serviced?
In South Florida's year-round cooling season, most commercial systems should be inspected quarterly, with coil cleaning and refrigerant checks at least twice a year. Heavier-use spaces like restaurants benefit from monthly filter and condensate attention.
Do you offer HVAC maintenance contracts?
Yes. Our maintenance plans cover scheduled inspections, priority emergency response and preferred repair rates across one building or an entire portfolio. See the Maintenance Plans page for how they're structured.
