Backup Power Since 1976 CAC029376

Home Generators

In Florida the reason to want backup power is the air conditioning, and the air conditioner is also what decides how big the generator has to be. Get that decision right and the whole project changes shape.

The Straight Answer

The Air Conditioner Sizes The Generator

Lights, a refrigerator and a few outlets are a small electrical load. A central air conditioner is not, and its starting surge is larger still. In a Florida outage the cooling is the whole point, which means the AC drives the generator size and therefore most of the cost.

That is why this belongs on an HVAC company's site rather than being purely an electrical question. Whether your system is single-stage or inverter-driven, whether a soft starter can reduce the surge, and whether one ductless head could cover the occupied part of the house are all decisions that change the generator you need.

Get those right and the project can be substantially smaller. Skip them and you buy capacity for a house you are not going to be living in at full tilt during a hurricane anyway.

What Prompts The Call

What An Outage Actually Costs You

Worth ranking these honestly before sizing anything, because the first one is a safety matter and the others are inconvenience or expense.

The House Gets Dangerous

Heat and humidity make a sealed Florida house genuinely unsafe within hours, and it is worse for the very young, the elderly and anyone unwell.

Medical Equipment

Oxygen concentrators, CPAP and refrigerated medication. Where this applies, backup power stops being a comfort purchase and the sizing conversation changes.

Well Pumps And Sump Pumps

No power means no water on a well, and no sump means water where you do not want it. Both are motor loads that need accounting for.

Food, Work And Security

A full freezer, a home office that has to function, and alarm and camera systems that go blind. Real costs, but the ones to weigh last.

Worth knowing: before you price anything, decide honestly what has to keep running. Whole-home backup with central air is the largest and most expensive answer. For many households, essential circuits plus a single ductless head keeping one or two rooms comfortable does the actual job for a fraction of the cost, and a soft starter on the existing compressor can cut the surge enough to drop a generator size. That conversation is worth having before anyone quotes you equipment.

Three Levels Of Backup

What Each One Actually Covers

The middle option is the one most people should look at first and the one least often presented.

What You Are Weighing Portable plus inlet Standby, essential circuits Standby, whole home
What it powers A handful of circuits you choose Selected circuits, permanently wired Everything, including central AC
Runs central air conditioning Rarely. Usually a mini-split at most Sometimes, with a soft starter Yes. This is what the size buys
Automatic or manual Manual. Someone has to be home Automatic within seconds Automatic within seconds
Fuel Petrol you have to store and fetch Natural gas or propane, continuous Natural gas or propane, higher draw
When this is right Short outages, someone always home Most households, honestly Medical need, or a house you cannot leave
Worth knowing: two things that get missed and only show up when you need the thing. First, fuel supply capacity. A generator sized correctly on paper will still stumble if the gas meter or propane tank cannot deliver the flow under full load, and that gets discovered during the first real outage rather than at commissioning. Second, exercise. A standby generator that never runs will not start when it matters, so ask what the self-test schedule is and who is checking it. Both belong in the quote, not the small print.

The Total Comfort Way

How We Approach It

The first two steps decide the size and therefore the price. Everything after that is execution.

STEP 01

Priorities Before Equipment

What genuinely has to run, in what order, and for how long. This conversation moves the cost more than any product choice, and it happens before anyone looks at a catalogue.

STEP 02

Load Study Including Starting Surge

Running loads measured and the air conditioner's starting surge accounted for specifically, since that peak rather than the steady draw is what sets the generator size.

STEP 03

Fuel Supply Verified

Gas meter capacity or propane tank and regulator sizing checked against the generator's demand under load, rather than assumed from the connection being present.

STEP 04

Transfer Switch And Placement

Transfer switch specified and installed, panel work carried out under the appropriate electrical licence, and the unit sited with clearance and storm exposure in mind.

STEP 05

Commissioned Under Load, Exercise Set

Tested transferring an actual load rather than merely starting, then the self-test schedule configured and explained so the thing is still working next hurricane season.

Common Questions

Generator Questions

It can, and that is the single biggest factor in what the system costs. A central air conditioner draws a large running load and a much larger starting surge, and the generator has to cover the surge.

There are cheaper routes to a cool house during an outage. A soft starter reduces the surge. A single ductless head cooling the rooms you are actually using needs a fraction of the capacity. We would rather work through those than sell you the largest unit in the range.

Essential circuits suits most households better than they expect, and it is the option least often put in front of them.

Whole-home backup earns its cost where there is a medical requirement, a well and sump to keep running, or a property that cannot simply be left. Otherwise, powering the parts of the house you will genuinely occupy during a storm is both cheaper to buy and cheaper to fuel.

Natural gas where the supply exists, because it does not need refilling and does not run out mid-outage. Propane where it does not, with the tank sized for the days you want to cover.

In both cases the question is delivery capacity rather than availability. A meter or regulator that cannot supply the flow the generator wants under full load will cause it to stumble, and that only reveals itself when the power is actually off.

Annually as a minimum, plus the automatic weekly or monthly self-test that the unit runs itself.

This is the part people neglect and it is the reason generators fail to start. An engine that has sat unused for two years is not reliable backup, it is decoration. If nobody is going to look after it, that is worth factoring into the decision before buying rather than after.

On natural gas, effectively as long as the supply holds, with pauses for oil and service intervals on a long outage. On propane, until the tank runs down, which is arithmetic you should do before you need it.

Work out your realistic worst case in days, not hours, and size the fuel accordingly. A generator that covers eighteen hours of a four-day outage has solved the easy part of the problem.

Not with a standby unit. It detects the outage and transfers automatically within seconds, which is much of the point for a property you might be away from during a storm.

A portable with an inlet connection is different: someone has to be there to set it up and start it. That is a real limitation for anyone who evacuates, and it is worth being clear-eyed about before choosing the cheaper option.

Home Generators

Sized For What You Actually Need.

Serving East Central Florida since 1976 under Florida HVAC licence CAC029376, with electrical work carried out under the appropriate licence. Priorities agreed before equipment, starting surge measured rather than estimated, fuel delivery capacity verified, and the unit commissioned transferring a real load with its exercise schedule set. If essential circuits and a mini-split would do the job, that is what we will recommend.
