How long does an AC installation take?

A straightforward residential changeout onto existing sound ductwork is usually a single day. Ductwork repairs, difficult air handler locations, or commercial jobs can take longer, and AIR SYSTEMS A/C confirms which applies before work begins.

What size air conditioning system do I need?

Sizing depends on square footage, ceiling height, insulation, window exposure and ductwork, not on the previously installed unit. In South Florida the common error is oversizing, which cools quickly but never runs long enough to remove humidity, leaving a home cold and clammy.

Do you offer financing on a new AC system?

Yes. Financing is available on new systems from AIR SYSTEMS A/C.

Do you pull the permit for AC replacement?

Yes. Air conditioning replacement requires a permit in Miami-Dade and Broward, and AIR SYSTEMS A/C handles permitting and inspection, with 879 permits pulled to date.

What does the AC warranty cover?

The manufacturer covers parts for 10 years on new equipment. AIR SYSTEMS A/C adds a 1-year labor warranty on replacements and new installations, so in the first year both the part and the labor are covered. Most manufacturer warranties require documented annual maintenance to remain valid.

& Replacement

A new system is a fifteen-year decision. We size it for your building rather than matching whatever was there before, pull the permit, and back the work with a full year of labor on top of the manufacturer's warranty.

What's Covered

The Warranty, In Plain Numbers

10Years on parts

Manufacturer warranty on every new system we install. Keep up with maintenance and it stays valid.

1Year of labor

Our own warranty on replacements and new installations. If it needs attention in that first year, the visit and the work are on us.

879Permits pulled

We permit the work and it passes inspection — which is what stops it becoming a problem when you sell the property.

Financing is available on new systems. Ask when you call and we will walk you through the options.

Sizing

Bigger Is Not Better in Florida

The most common mistake in South Florida is an oversized system. It cools the air quickly, satisfies the thermostat, and shuts off — never running long enough to pull the humidity out. You end up with a house that feels cold and clammy at the same time, a compressor that short-cycles itself to an early death, and a power bill that does not match the comfort.

We size on the building: square footage, ceiling height, insulation, window exposure, and how the ductwork actually runs. Not on what was there before, and not on a rule of thumb.

Existing ductwork inspected, not assumed
Old equipment and refrigerant removed properly
Permit pulled and inspection scheduled
System started, charged and verified before we leave

Timing

When Replacement Beats Another Repair

Nobody wants to hear it, and we are not going to tell you it is time when it is not. These are the situations where the money genuinely goes further on a new system.

Past twelve to fifteen years

Florida systems work harder than almost anywhere. Past that mark the efficiency has usually dropped enough that a new unit pays back part of itself monthly.

The compressor has failed

The single most expensive part. On an older system, replacing it often costs a meaningful fraction of a whole new unit.

Repairs are stacking up

Third or fourth call in two seasons. Each one is affordable on its own; together they are a down payment on equipment that will not fail again next month.

A leak in the evaporator coil

A leaking coil is a large repair. On an older system it is usually the moment to price both options side by side.

The bill keeps climbing

A system losing efficiency runs longer for the same result. If the bill rose but nothing else changed, the equipment is telling you something.

You are renovating anyway

If walls or ceilings are open, that is the cheapest ductwork will ever be. Worth doing the system at the same time.

Before You Buy

Installation Questions

A straightforward residential changeout — new equipment onto existing, sound ductwork — is usually a single day. If the ductwork needs work, if the air handler is in a difficult spot, or if it is a commercial job, it can run longer. We will tell you which one you have before we start, not partway through.

It depends on square footage, ceiling height, insulation, window exposure and ductwork — not on what was installed before. Matching the old unit repeats whatever mistake was made last time, and in South Florida the usual mistake is oversizing, which leaves a house cold and humid at once. We work it out from the building.

Yes, financing is available on new systems. A replacement is rarely something people plan for, and it usually happens in the worst week of the summer. Ask when you call and we will go through what is available.

Yes. AC replacement requires a permit in Miami-Dade and Broward, and we handle it — 879 permits pulled and counting. Unpermitted work tends to surface at the worst possible moment, usually during a sale or an insurance inspection.

Two separate things. The manufacturer covers parts for 10 years on the equipment. AIR SYSTEMS A/C covers labor for 1 year on replacements and new installations — so in that first year, both the part and the visit to fit it are covered. Most manufacturer warranties require documented annual maintenance to stay valid, which is worth knowing on day one rather than year six.
