How often should I service my AC in Miami?

At least once a year, and twice a year is better in South Florida than almost anywhere else. Systems here run close to year round with high humidity and salt air. A yearly tune-up keeps coils clean, catches a weak capacitor or a clogging drain line early, and keeps the manufacturer's warranty valid, since most warranties require documented maintenance.

Should I repair my air conditioner or replace it?

It depends on age, repair cost, and the condition of the rest of the system. A unit under about ten years old with one failed part is usually worth repairing. Past twelve to fifteen years, with repeated repairs or a failing compressor, the money is often better spent toward a new, more efficient system.

Why is my AC running but not cooling?

The most common causes are low refrigerant from a leak, a frozen evaporator coil, a dirty condenser, a failing capacitor, or a failed compressor. A clogged filter can also cause it. Beyond checking the filter, the system needs gauges on it to diagnose properly.

What size air conditioner do I need?

Sizing depends on square footage, ceiling height, insulation, window exposure and ductwork, not on what was installed before. Oversized systems cool quickly, shut off, and never run long enough to remove humidity, leaving a home that feels cold and clammy.

AIR SYSTEMS A/C is open Monday through Saturday from 8:00am to 7:00pm and Sunday from 8:00am to 5:00pm — seven days a week including weekends. We are not a 24-hour company, but calls during business hours get a fast response and same-day appointments are booked whenever the schedule allows.

New systems carry a 10-year manufacturer warranty on parts, plus 1 year of labor warranty from AIR SYSTEMS A/C on replacements and new installations. Financing is available on new systems.

Don't Wait For A Breakdown

Is Your System Trying To Tell You Something?

In Miami, an air conditioner works nearly year round. Small problems turn into expensive ones fast. If any of these sound familiar, call us before the system quits.

It runs but doesn't cool

Air is moving and the unit is on, but the house never gets comfortable. Often low refrigerant, a failing compressor, or a system too small for the space.

Warm air from the vents

Usually a refrigerant leak, a frozen coil, or a compressor that has stopped doing its job. This one rarely fixes itself.

Water around the air handler

A clogged condensate drain line backs up quickly in Florida humidity and can damage drywall, flooring and ceilings.

Grinding, rattling or squealing

New noises mean a mechanical part is failing. Catching it early is the difference between a repair and a replacement.

The power bill jumped

A system losing efficiency runs longer to reach the same temperature. The bill climbs before the unit ever fails.

It turns on and off constantly

Short cycling wears out the compressor, the most expensive part of the system, and it never properly removes humidity.

For Business Owners

When Downtime Costs You Money

A restaurant with a failed walk-in cooler is losing inventory by the hour. An office with no air conditioning sends people home. Commercial work is not just a bigger version of residential work, and we have been doing it for over a decade.

Our team handles walk-in coolers and freezers, rooftop units, duct detectors, and full mechanical installations — from a single changeout to projects in the hundreds of thousands of dollars. We pull our own permits and we do the work to code, every time.

Questions We Hear Every Week

Frequently Asked Questions

At least once a year, and twice a year is better here than almost anywhere else in the country. South Florida systems run close to year round with high humidity and salt in the air, which is much harder on equipment than a system that gets a winter off. A yearly tune-up keeps coils clean, catches a weak capacitor or a clogging drain line early, and keeps the manufacturer's warranty valid — most warranties require documented maintenance.

It comes down to age, the cost of the repair, and how the rest of the system is holding up. A unit under about ten years old with one failed part is usually worth repairing. Once a system is past twelve to fifteen years, is needing repeated repairs, or has a failing compressor, the repair money is often better spent toward a new, more efficient system that lowers the power bill. We will tell you honestly which side of that line you are on, and we will give you both numbers so you can decide.

The most common causes are low refrigerant from a leak, a frozen evaporator coil, a dirty condenser, a failing capacitor, or a compressor that has stopped working. A clogged filter can cause it too, which is the one thing worth checking yourself before you call. Beyond that, the system needs gauges on it — adding refrigerant to a system that is leaking is a temporary fix that costs more over time than finding the leak.

Yes. Walk-in coolers and freezers, rooftop units, duct detectors and full commercial mechanical work are a core part of what we do, alongside residential air conditioning. We understand that for a restaurant or a market, refrigeration going down is not an inconvenience — it is inventory walking out the door.

Yes. AIR SYSTEMS A/C, LLC holds Florida state license CAC033544 as a certified air conditioning contractor, and we are fully insured. We pull permits for the work that requires them, which is how you know the job will pass inspection and will not become a problem when you sell the property.

It depends on the square footage, the ceiling height, insulation, window exposure and how the ductwork is laid out — not on what was there before. Oversized systems are a common problem in Florida: they cool the air quickly, shut off, and never run long enough to pull the humidity out, which leaves a house that feels cold and clammy. We size the system for your building rather than simply matching the old one.

We are open Monday through Saturday, 8:00am to 7:00pm, and Sunday, 8:00am to 5:00pm — seven days a week, including weekends, which is when a lot of systems seem to pick to quit. We are not a 24-hour company, but calls that come in during business hours get a fast response and we book same-day appointments whenever the schedule allows.

We install Rheem, Goodman, T.G.M., Everwell and ComfortStar, and we service all major brands regardless of who installed them. Every new system comes with a 10-year manufacturer warranty on parts, and AIR SYSTEMS A/C adds 1 year of labor warranty on replacements and new installations — so if something needs attention in that first year, the visit and the work are covered. Financing is available on new systems.

We serve Miami-Dade and Broward counties and up into Boca Raton, working out of our shop in Opa-locka. That covers Miami, Hialeah, Doral, Miami Gardens, Aventura, Miami Beach, Coral Gables, Kendall, Homestead, Hollywood, Pembroke Pines, Fort Lauderdale, Coral Springs and the cities around them. If you are not sure whether you are in range, just call.
