AC Installation & Replacement | Tampa Bay

In this climate a system has two jobs: lower the temperature and remove moisture. An oversized unit does the first quickly and then shuts off before it has run long enough to do the second. The house ends up cold and clammy at the same time, the compressor short-cycles, and the equipment wears out faster than it should.

Sizing is determined by a load calculation covering square footage, ceiling height, window area and orientation, insulation levels, duct condition and infiltration. Square footage alone is not a calculation, which is why two houses of identical size can legitimately need different equipment.

What a replacement involves beyond the box

The outdoor condenser and indoor air handler are the visible parts, but a replacement also has to consider the line set, the drain, the electrical supply and the duct system. Reusing an undersized or leaking duct system with new equipment is a common way to spend money on a system that still does not perform. Where the duct system is the real constraint, the equipment change alone will not fix it.

Refrigerant transition

The industry has been moving away from R-410A toward lower global warming potential refrigerants including R-454B and R-32. Equipment and refrigerant handling requirements are changing with it. The practical implications for a homeowner are about serviceability and future parts availability rather than performance, and it is worth asking what a new system uses before committing.

Efficiency ratings and what they mean here

Efficiency standards for new equipment have tightened, and the ratings are calculated under test conditions. What a system actually delivers depends on the installation: correct charge, sealed ducts, adequate return air and a clean coil. A high-efficiency unit installed badly will underperform a standard unit installed properly, which is why the installation quality matters more than the badge on the box.

When to call

The system has failed and is beyond economical repair
Your system is over fifteen years old
Rooms never reach the setpoint despite running constantly
The house feels cold and clammy at the same time
You are building or renovating and need a system designed
You are replacing a system and want efficiency improved

How the work is handled

Load calculation covering the building envelope and orientation
Assess the duct system, electrical supply and drain
Select equipment matched to the calculated load
Permit, install and charge the system to specification
Verify airflow, charge and temperature split before handover

What affects the cost

We do not quote a number before seeing the property, because the same job on two similar houses can need different work. These are the factors that move the scope:

Calculated load and the equipment capacity it requires
Efficiency tier selected and the refrigerant the system uses
Whether the duct system needs repair, sealing or replacement
Line set, drain and electrical work required
Access to the attic for the air handler
Permit requirements and any load management or controls added

Frequently asked questions

How long does a new AC system last here?

Typically twelve to fifteen years, and often at the lower end because a system in this climate runs far more hours annually than in milder regions. Attic-installed air handlers also operate in extreme heat, which shortens component life further.

Do I need a bigger system for a bigger house?

Capacity follows the calculated load, which depends on insulation, window area, orientation and duct condition as much as square footage. Two identically sized houses can legitimately need different equipment, which is why the calculation comes before the quote.

Should I replace the ductwork at the same time?

If it is leaking, undersized or poorly laid out, yes. New equipment connected to a bad duct system delivers most of the same problems. It is usually cheaper to address both together than to revisit the ducts afterwards.

What refrigerant will a new system use?

The industry has been transitioning from R-410A to lower global warming potential refrigerants including R-454B and R-32. This affects serviceability and future parts availability more than performance, and it is worth asking before you commit.
