Generator Questions, Answered
Everything homeowners ask us before they book an assessment — sizing, fuel, permits, associations, timing, and what actually happens on install day. If your question is not here, call us and ask it directly.
Cost and value
How much does a whole-home generator cost installed?
There is no honest flat answer, and any company that gives you one over the phone is guessing. Installed cost depends on the size of the system, whether you are on natural gas or propane, how far the unit sits from your panel and fuel source, the condition of your electrical service, and whether your property needs an elevated pad. Every line is itemized in a written proposal after a free in-home assessment, with no pressure attached.
Why is propane more expensive than natural gas?
A natural gas installation ties into a line that is already at your house. A propane installation means adding a tank sized for meaningful runtime, plus the gas line, the pad, and the coordination with a propane supplier. That is real additional scope, and it shows up in the quote. It is worth knowing before you start comparing numbers between two houses on the same street.
Does a standby generator add value to my home?
It is a permanent, permitted improvement wired into the home’s electrical system, and buyers in this market understand what it is for. It also stays with the house. We would not tell you to buy one as an investment — buy it because you do not want to lose air conditioning for four days — but it is not money that disappears.
Do you offer financing?
Yes. Flexible payment options are available and we go over them during your free consultation.
Is there an annual cost to owning one?
Budget for routine maintenance the same way you would for an HVAC system — oil, filters, and a periodic inspection to keep the warranty intact and the unit ready. We will lay out what the maintenance schedule looks like for your specific model during the consultation.
Sizing
What size generator do I need?
Square footage is where people start, and it is the least useful number in the calculation. What actually determines size is your air conditioning load — how many units, what tonnage, and how they start. A 3,000 square foot home with two AC units and a pool pump may need more generator than a 5,000 square foot home with one. We run a load calculation at your house rather than estimating from the curb.
Can one generator really power my entire house?
For most Tampa Bay homes, yes — that is what whole-home coverage means. Central air, refrigeration, lights, well pump, security system, and Wi-Fi all stay on. For very large homes with heavy simultaneous loads, we either size up or use load management so the system prioritizes correctly. Either way you find out during the assessment, not after.
What is load management and do I need it?
Load management lets the system shed non-essential circuits for a moment when several large loads try to start at once — typically air conditioners. It means you can often run a whole house on a smaller, less expensive unit without noticing any difference. Whether it makes sense for you depends on how your loads are distributed.
Will a generator run my air conditioning?
Yes, as long as it is sized for that load from the beginning. This is the single most important question in the whole process, because in a Florida summer a generator that cannot run your AC has not solved your problem.
What if I add a pool or an addition later?
Tell us during the assessment. It is far cheaper to size for a load you are planning than to replace a unit two years in. We would rather spec correctly once.
Fuel
Natural gas or propane — which do I need?
Whichever reaches your address. Natural gas means effectively unlimited runtime with no refueling, which is why it is the first choice where it is available. Where gas does not reach your street, a properly sized propane tank is entirely dependable. We confirm what is actually available at your address during the assessment rather than assuming based on the neighborhood.
How do I know if I have natural gas?
If you have a gas range, gas water heater, or gas dryer, you almost certainly do. If you are not sure, we check as part of the assessment. Availability varies street to street in a lot of Tampa Bay, so a neighbor having it does not guarantee you do.
How long will a propane tank last?
It depends on the tank size and how heavily the system is loaded, which is exactly why we size the tank alongside the generator rather than defaulting to a standard size. The goal is enough runtime to get through a realistic multi-day outage without a mid-storm delivery.
Who handles the propane tank and the gas line?
We coordinate it as part of the project — tank placement, the gas line, and the permitting all move together. You are not managing three vendors.
Permits, inspections, and associations
Do I need a permit?
Yes. A standby generator installation requires electrical and gas permits and a final inspection. Anyone offering to skip that is exposing you on your warranty, your insurance, and your eventual home sale. We pull every permit as the licensed contractor of record.
Which authority permits my address?
It depends where you live. Most of Hillsborough and Pasco is unincorporated and permits through the county. Addresses inside the City of Tampa, Temple Terrace, Plant City, New Port Richey, Zephyrhills and Dade City go through their own building departments. We confirm the right jurisdiction before anything is filed.
How long does permitting take?
It varies by jurisdiction and by time of year, and it is usually the longest single step in the project. That is the main reason we tell people to start before hurricane season rather than during it.
Will my HOA approve a standby generator?
In almost every case, yes. Standby generators are a familiar sight across Tampa Bay’s deed-restricted communities. Approval is a matter of submitting the placement drawings and product details the architectural review asks for, and we prepare that package as part of the project.
Do you handle the association paperwork too?
We prepare it. You submit it, because associations generally require the homeowner of record to file. We make sure what you submit is complete the first time.
Installation
How long does the whole process take?
On-site installation is usually one to two days. The full project — consultation, association review where it applies, permitting, equipment delivery, installation, and final inspection — typically spans a few weeks. Starting before hurricane season keeps you well ahead of the rush.
What happens during the free in-home assessment?
We walk the property, look at your electrical panel and service, calculate your actual load, identify where the unit can sit with proper clearances, confirm your fuel situation, and talk through what the project involves. You get a written proposal. There is no obligation and no pressure.
Where will the generator sit?
Somewhere that satisfies code clearances, keeps required distance from windows and openings, works with your fuel and electrical runs, and does not dominate your outdoor living space. On larger lots there is real flexibility. On tighter lots there is usually one right answer, and we will show you why.
Does my power get shut off during installation?
There is a planned interruption while we tie into the panel and set the transfer switch. It is scheduled, it is not all day, and you will know when it is happening.
My electrical panel is old. Is that a problem?
It is common and it is a normal part of the job, not a dealbreaker. We evaluate the panel during the assessment and handle any electrical work the installation needs under the same permit, as a Florida State Certified Electrical Contractor.
Do you use subcontractors?
The electrical work is performed under our own state contractor license. We tell you who is doing what before the project starts.
Living with it
How fast does it come on?
The transfer switch senses the outage and starts the generator in about ten seconds. You do not do anything. You do not have to be home.
Is it loud?
Generac home standby units are designed for residential settings, and the self-test mode runs at lower speed specifically to keep it quiet. It is audible when running under load — it is an engine — but it is built to live in a backyard on a normal street.
Does it run a test on its own?
Yes, on a schedule you choose. The self-test is short and confirms the unit will start when it actually matters. Picking a considerate day and time is part of the handover.
Can I monitor it from my phone?
Yes. Generac’s Mobile Link lets you check status and get maintenance alerts from anywhere. We set it up and walk you through it before we leave.
What maintenance does it need?
Oil and filter changes on a set interval, plus a periodic inspection — much like an HVAC system. Staying on schedule protects your warranty and, more importantly, means it starts the day you need it.
What is the warranty?
Every Generac standby generator carries a manufacturer’s limited warranty. Registering it correctly at commissioning matters, and we handle that as part of the install.
Working with us
What areas do you serve?
Hillsborough and Pasco counties — including South Tampa, Carrollwood, Westchase, Citrus Park, Keystone, Lutz, Land O’ Lakes, Odessa, Trinity, Brandon, Riverview and the surrounding communities.
Why buy from an authorized Generac dealer instead of a big-box store?
Because the equipment is the easy part. Correct sizing, code-compliant placement, permitting, panel work, gas coordination, inspection, and warranty registration are where installations go wrong — and a box on a pallet does not do any of that. One accountable Florida State Certified Electrical Contractor handles the whole project.
Do you install generators you did not sell?
We focus on complete installations of new Generac standby systems, from sizing through commissioning.
What is the first step?
A free in-home assessment. Call us or request a quote and we will schedule it.
