Florida Electric Bills – What to Expect and How to Lower Your Costs

Last updated November 2018

One of the most common questions I get from people relocating to Tampa Bay – and even from locals buying their first home – is about electric bills. How much is electricity in Florida? Why is my bill so high? Is there anything I can actually do about it? I’m Barrett Henry with RE/MAX Collective, and after helping families buy homes across Brandon, Riverview, Valrico, and the broader Tampa Bay area, I’ve had this conversation hundreds of times. The short answer is that Florida electric bills are higher than most of the country, and air conditioning is the reason. The longer answer involves understanding your utility provider, knowing what drives your costs, and making smart choices – both when you’re shopping for a home and after you move in. This guide covers all of it.

Average Electric Bill in Tampa Bay by Home Size

These are realistic averages based on what I hear from homeowners across the Tampa Bay area. Your actual bill will vary based on the age of your home, your AC system, your thermostat habits, and whether you have a pool or electric water heater. But this gives you a solid baseline for budgeting.

If those summer numbers look high, welcome to Florida. The months from June through September are where your electric bill earns its reputation. I always tell buyers to budget for the summer peak, not the annual average – because the summer peak is what hits your bank account when you’re also paying for back-to-school, property taxes, and everything else.

Average Electric Bills in Tampa Bay by Month and Season

Tampa Bay has a subtropical climate, which means hot, humid summers and mild, dry winters. That seasonal swing drives a massive difference in your electric bill from month to month. Here’s what a typical billing cycle looks like for a 2,000-square-foot home in the Brandon area.

The pattern is clear: your AC basically hibernates from December through February, ramps up in the spring, and runs nonstop from June through September. July and August are typically the most expensive months, when outdoor temperatures hover around 91 degrees and humidity makes it feel like 100+. That’s when your AC is running 14 to 18 hours a day just to maintain 76 degrees inside.

TECO Energy vs. Duke Energy in Tampa Bay

Your electric provider in Tampa Bay depends on where you live – you don’t get to choose. The two main providers serving the area are Tampa Electric (TECO Energy) and Duke Energy Florida. Here’s how they compare.

If you’re buying a home in Brandon, Riverview, or Valrico, you’ll almost certainly be a TECO customer. TECO serves virtually all of Hillsborough County. Duke Energy covers parts of the surrounding counties. Rates between the two are fairly similar – the bigger factor in your bill is always going to be your home’s efficiency and your thermostat settings, not which utility serves your address.

Both providers offer budget billing programs that average your annual costs into equal monthly payments. This can be helpful for budgeting, especially if you prefer a predictable payment over the summer spike and winter dip cycle. Just know that you’ll settle up at the end of the year if your actual usage was higher or lower than the average.

Why Florida Electric Bills Are Higher Than Most States

Florida consistently ranks in the top 10 states for total monthly electric bills. It’s not because our electricity rates are outrageous – Florida’s per-kilowatt-hour rate is actually close to the national average. The issue is that we use a lot more electricity than most states, primarily because of air conditioning.

• AC runs 8-10 months per year – In most states, heating and cooling are seasonal. In Florida, your AC runs from March through November, and in the summer it runs nearly around the clock. Heating costs are minimal – most Floridians only run heat for a handful of days per year.
• High humidity increases AC workload – Your air conditioner doesn’t just cool the air, it removes moisture. Tampa Bay’s summer humidity levels regularly exceed 80%, which means your AC is working overtime just to dehumidify your home on top of cooling it.
• Older housing stock – Many homes in the Tampa Bay area were built in the 1970s through 1990s with insulation, windows, and ductwork that don’t meet current energy efficiency standards. These homes leak conditioned air and force the AC to work harder.
• Electric water heaters – Florida has a very high percentage of homes with electric water heaters rather than gas. An electric water heater is typically the second-largest energy consumer in a Florida home after the AC.
• Pool pumps – A significant number of Tampa Bay homes have swimming pools, and pool pumps draw substantial electricity – especially older single-speed models that run 8-12 hours per day.

The bottom line: your Florida electric bill is high because your AC is doing a lot of work for a lot of months. Almost everything you can do to lower your bill involves either making your AC work less or making it work more efficiently.

Biggest Energy Hogs in a Florida Home

If you want to lower your electric bill, you need to know where the money is going. Here’s a rough breakdown of energy consumption in a typical Tampa Bay home.

Your AC is responsible for roughly half your electric bill. Your water heater is a distant second. If you have a pool, the pump comes in third. Everything else combined – lights, appliances, electronics – accounts for maybe a quarter of your total bill. This means the biggest savings opportunities are in cooling efficiency, water heating, and pool pump optimization. Turning off lights is good practice, but it won’t put a meaningful dent in a $300 summer electric bill.

How to Lower Your Electric Bill in Tampa Bay

I’ve organized these tips by category, starting with the highest-impact changes and working down to the smaller stuff. Some of these are free, some cost money upfront but pay for themselves, and some are investments that make sense when you’re already replacing equipment.

Air Conditioning – The Big Wins

• Set your thermostat to 78F when you’re home – Every degree below 78 adds roughly 6-8% to your cooling costs. Setting the AC to 72 degrees in a Florida summer isn’t just expensive – it’s making your system work at near-maximum capacity all day.
• Raise the temp when you’re away – Set it to 82-85F when nobody is home. A programmable or smart thermostat handles this automatically. There’s no reason to cool an empty house to 76 degrees.
• Change your air filter every 30-60 days – A dirty filter restricts airflow and forces your AC to work harder. This is the cheapest, easiest thing you can do, and most homeowners don’t do it often enough. Filters cost $5-$15 each.
• Get your AC serviced annually – A professional tune-up ($80-$150) keeps refrigerant levels correct, coils clean, and the system running efficiently. A neglected system uses 10-25% more energy than a well-maintained one.
• Seal your ductwork – Leaky ducts in a Florida attic can waste 20-30% of your cooled air before it ever reaches your living space. Duct sealing costs $300-$1,000 and is one of the best returns on investment for energy savings.
• Add attic insulation – Florida attics can reach 140-160 degrees in the summer. If your insulation is thin or compressed, heat radiates down into your living space and your AC fights it all day. Bringing your attic insulation up to R-30 or R-38 costs $1,000-$2,500 for a typical home and can reduce cooling costs by 10-20%.
• Use ceiling fans – Fans don’t cool the air, but they create a wind-chill effect that lets you set your thermostat 2-4 degrees higher while feeling just as comfortable. A ceiling fan costs about 1 cent per hour to run. Your AC costs 20-40 cents per hour.

Water Heating

• Lower your water heater to 120F – Most water heaters ship set at 140F, which is hotter than necessary and wastes energy maintaining that temperature 24/7.
• Insulate your hot water pipes – Foam pipe insulation costs about $10 for a whole house and reduces heat loss as water travels from the heater to your faucets.
• Consider a heat pump water heater – These use 50-65% less electricity than a standard electric tank water heater. They cost more upfront ($1,200-$2,500 installed) but pay for themselves within 2-4 years in Florida’s climate. If your current water heater is approaching 10 years old, a heat pump model is worth considering as a replacement.
• Use cold water for laundry – Modern detergents work fine in cold water. Switching to cold-water laundry can save $50-$100 per year on water heating alone.

Pool Pump Savings

• Upgrade to a variable-speed pool pump – This is one of the best energy investments a pool owner can make. Variable-speed pumps adjust their speed based on demand and use 50-70% less electricity than single-speed models. A variable-speed pump costs $800-$1,500 installed and typically pays for itself within 1-2 years. Florida law now requires variable-speed pumps on new pool construction and pump replacements.
• Reduce pump run time – Many pool owners run their pump far longer than necessary. Most residential pools in Florida only need 6-8 hours of circulation per day. Experiment with reducing your run time gradually and monitoring water clarity.
• Run the pump during off-peak hours – Running your pool pump overnight or in the early morning avoids the peak demand period and can be slightly cheaper if your utility offers time-of-use rates.

Lighting and Appliances

• Switch all bulbs to LED – If you haven’t already, replace every incandescent and CFL bulb in your home with LED. LEDs use 75-80% less energy and last 15-25 times longer. A whole-house LED conversion costs $30-$80 and saves $100-$200 per year.
• Unplug or use power strips for electronics – TVs, gaming consoles, phone chargers, and cable boxes draw power even when they’re “off.” This phantom load can add $50-$100 per year. Smart power strips that cut power to idle devices are a simple fix.
• Run your dishwasher and washing machine with full loads – Half-loads use nearly the same amount of energy as full loads. Wait until you have a full load to run these appliances.
• Use your dryer’s moisture sensor – If your dryer has a moisture sensor or auto-dry setting, use it. Timed drying often runs longer than necessary, wasting energy and wearing out clothes faster.
• Keep your refrigerator at 37-40F and freezer at 0-5F – Colder settings waste energy without meaningfully improving food preservation.

Windows and Insulation

• Close blinds and curtains on sun-facing windows – Direct sunlight streaming through windows heats up your rooms and makes your AC work harder. This is free and immediate.
• Consider window tinting or solar film – Window tinting can block 40-70% of solar heat gain through your windows. Professional installation costs $5-$12 per square foot and can noticeably reduce cooling costs in rooms with large windows or western exposure.
• Upgrade to impact or double-pane windows – If you’re already replacing windows for hurricane protection, the energy savings are a bonus. Double-pane low-E windows significantly reduce heat transfer compared to single-pane windows common in older Florida homes.
• Seal gaps around doors and windows – Weatherstripping and caulking around exterior doors and windows prevents conditioned air from escaping. A $20-$50 investment in weatherstripping materials can make a noticeable difference.

Smart Thermostats and Energy-Efficient Upgrades

A smart thermostat is one of the easiest and most effective upgrades you can make. Models from brands like Nest, Ecobee, and Honeywell learn your schedule, adjust temperatures automatically, and let you control your AC from your phone. The typical cost is $130-$250 installed, and most homeowners save 10-15% on their cooling costs – which in Florida can mean $150-$300 per year. That’s a payback period of less than a year in most cases.

Beyond the thermostat, here are other energy-efficient upgrades worth considering for a Florida home:

• High-efficiency AC system (16+ SEER) – If your AC is more than 10-12 years old, a newer high-efficiency system can reduce cooling costs by 20-40%. A new system costs $4,000-$8,000 installed but pays dividends every month in a Florida climate. Look for SEER ratings of 16 or higher.
• Radiant barrier in the attic – A radiant barrier is a reflective material installed in your attic that reflects heat away from your living space. It costs $500-$1,500 and can reduce cooling costs by 5-10% by keeping your attic temperature significantly lower.
• Heat pump water heater – As mentioned above, these cut water heating costs by 50-65%. In a state where you’re heating water year-round, the savings add up fast.
• Variable-speed pool pump – Already covered, but worth emphasizing. If you have a pool and a single-speed pump, this upgrade pays for itself faster than almost anything else on this list.
• ENERGY STAR appliances – When it’s time to replace your refrigerator, dishwasher, or washing machine, choose ENERGY STAR-rated models. The savings per appliance are modest ($20-$80 per year each) but they add up across multiple appliances over time.

Solar Panels in Tampa Bay – Pros, Cons, Costs, and ROI

Tampa Bay gets an average of 244 sunny days per year, which makes it one of the better locations in the country for solar energy production. Solar panel installations have become increasingly common in Brandon, Riverview, and Valrico over the past several years, and the cost has come down significantly. But solar isn’t right for every home or every homeowner, so let’s look at the real numbers.

Cost of Solar Panels in Tampa Bay

A typical residential solar installation in the Tampa Bay area runs 6 to 10 kilowatts (kW) in size, which is enough to offset 60-100% of an average home’s electricity usage. The cost breakdown looks like this:

The federal solar Investment Tax Credit (ITC) currently allows you to deduct 30% of the cost of a solar installation from your federal taxes. Florida also offers a property tax exemption for solar panels – meaning the added value of solar panels to your home is exempt from property tax assessment. There’s no state sales tax on solar equipment in Florida either.

Solar ROI and Payback Period

For most Tampa Bay homeowners, the payback period on a solar installation is 8 to 12 years after the federal tax credit. With panels warranted for 25 years, that means 13-17 years of essentially free electricity after you’ve recouped your investment. The exact payback depends on your electricity usage, system size, roof orientation (south-facing is ideal), shading, and how you finance the system. Homes with high electric bills ($200+ per month) see faster payback periods.

Pros and Cons of Solar Panels

Here’s my honest assessment based on what I’ve seen from homeowners in the Tampa Bay market.

Pros

• ✓ Dramatically lower electric bills – Many solar homeowners see 60-100% reductions in their electric bills, keeping only the base utility charge
• ✓ Protection against rate increases – Electricity rates have historically increased 2-3% per year. Solar locks in your energy cost for 25+ years
• ✓ Federal and state incentives – The 30% federal tax credit plus Florida’s property tax and sales tax exemptions significantly reduce the net cost
• ✓ Increased home value – Studies show solar panels add roughly $10,000-$20,000 to a home’s resale value, and the property tax exemption means you don’t pay tax on that added value
• ✓ Tampa Bay sunshine – 244 sunny days per year means strong, consistent energy production
• ✓ Low maintenance – Solar panels have no moving parts and require very little maintenance beyond occasional cleaning

Cons

• ✗ High upfront cost – Even after the tax credit, you’re looking at $10,000-$21,000 out of pocket or financing costs
• ✗ Roof condition matters – If your roof is more than 10 years old, you may need to replace it before or during solar installation, adding significant cost
• ✗ Not all roofs are suitable – Heavily shaded roofs, north-facing roofs, or roofs with complex angles may not produce enough energy to justify the investment
• ✗ HOA restrictions – While Florida law protects homeowners’ right to install solar panels, some HOAs try to impose aesthetic restrictions on panel placement. Know your rights and your HOA’s rules before committing
• ✗ Net metering changes – Utility companies periodically revise their net metering policies, which can affect how much you’re credited for excess energy your panels send back to the grid
• ✗ Hurricane exposure – While modern panels are rated for high winds, severe storms remain a concern. Your homeowners insurance should cover solar panel damage, but verify this with your carrier
• ✗ Leased vs. owned complications – If you lease solar panels rather than buying them, the lease can complicate a home sale because the new buyer has to assume the lease or you have to buy out the contract

My take: if you own your home, have a newer roof with good southern exposure, plan to stay for at least 8-10 years, and have the budget for it, solar is a strong investment in the Tampa Bay area. If you’re planning to sell within a few years, or if your roof needs replacement, the math probably doesn’t work right now.

How Electric Costs Affect Home Buying Decisions

As a real estate agent, I see electric costs influence home buying decisions more than most people expect. Here’s what I tell my clients to think about when evaluating a home’s energy profile.

• Ask for the seller’s electric bills – Request 12 months of utility bills during your due diligence period. This gives you a real-world picture of what the home costs to cool and power. If the seller’s summer bills are $400+ on a 2,000-square-foot home, that’s a red flag that the AC system, insulation, or ductwork may need attention.
• Check the AC system age – The AC unit is listed on the home inspection report with its manufacture date. A system that’s 12-15 years old is approaching the end of its useful life in Florida and will likely be less efficient than a modern system. Factor a $4,000-$8,000 AC replacement into your budget if the system is aging.
• Evaluate the windows – Single-pane windows in a Florida home are a major energy liability. If the home has original single-pane windows from the 1980s or 1990s, your cooling costs will be significantly higher than a comparable home with double-pane or impact windows.
• Look at the insulation – Your home inspector should check attic insulation depth and condition. Many older Florida homes have R-13 or less in the attic, when R-30 to R-38 is recommended. Inadequate insulation means higher electric bills year after year.
• Consider the lot orientation – A home with large, unshaded west-facing windows will absorb significantly more solar heat in the afternoon, driving up cooling costs. Mature trees providing shade on the west and south sides of a home can reduce cooling costs by 10-25%.

I always remind buyers: the mortgage payment is only part of the cost of owning a home. Electric bills, insurance, property taxes, and maintenance all add up. A home that’s $20,000 cheaper but costs $150 more per month in electricity isn’t actually saving you money. Understanding the full picture before you make an offer is part of buying smart.

Energy-Efficient Home Features to Look For

If keeping energy costs low is a priority – and in Florida it should be – here are the features I tell my buyers to look for when shopping for a home.

• Newer AC system (under 8 years old) with 16+ SEER rating – This is the single biggest factor in your cooling costs
• Double-pane or impact-resistant windows – Better insulation and less heat transfer than single-pane
• Adequate attic insulation (R-30 or higher) – Keeps attic heat from radiating into your living space
• Sealed and insulated ductwork – Ducts running through an unconditioned attic lose enormous amounts of cooled air if they’re not properly sealed
• Programmable or smart thermostat – Allows automatic temperature adjustments based on your schedule
• LED lighting throughout – Indicates the home has been updated and the owner pays attention to efficiency
• Variable-speed pool pump – If the home has a pool, this saves $50-$100+ per month compared to a single-speed pump
• Solar panels (owned, not leased) – Owned solar panels add value and reduce or eliminate electric bills
• Light-colored roof – Reflects more sunlight and reduces attic temperatures compared to dark shingles
• Mature shade trees on the west and south sides – Natural shading reduces solar heat gain significantly
• Concrete block (CBS) construction – Better thermal mass and insulation properties than wood-frame construction in Florida’s climate

A home with most of these features will cost noticeably less to cool than a comparable home without them. Over 10-20 years of ownership, the cumulative savings on electric bills can amount to $15,000-$40,000 or more. That’s real money, and it’s one of the reasons I push my buyers to look beyond the kitchen countertops and pay attention to what’s behind the walls and on the roof.

Frequently Asked Questions About Florida Electric Bills

What is the average electric bill in Tampa Bay?

For a typical 2,000-square-foot single-family home in the Brandon/Tampa Bay area, the average electric bill runs $130-$180 per month on an annual basis. During summer months (June through September), bills typically spike to $220-$320 per month due to heavy AC usage. Winter months (December through February) are much lower, usually $85-$130. Your specific bill depends on your home’s age, AC efficiency, insulation quality, thermostat settings, and whether you have a pool.

Why is my Florida electric bill so high in the summer?

Air conditioning is the primary reason. When outdoor temperatures reach 90+ degrees with 80%+ humidity from June through September, your AC system runs 14-18 hours per day to maintain a comfortable indoor temperature. AC accounts for 40-55% of your total electric bill, and that percentage climbs even higher in the summer months. The combination of extreme heat, high humidity, and long cooling seasons makes Florida summers expensive for every homeowner.

What temperature should I set my thermostat in Florida?

The Department of Energy recommends 78F when you’re home and awake, and 82-85F when you’re away or sleeping. Every degree below 78 adds roughly 6-8% to your cooling costs. Most of my clients settle on a range of 76-78 during the day and 74-76 at night with ceiling fans running. Using a smart thermostat that automatically adjusts when you’re away makes a significant difference.

Are solar panels worth it in Tampa Bay?

For homeowners who plan to stay in their home for 8-10+ years, have a newer roof with good southern exposure, and can afford the upfront investment (or favorable financing), solar panels are generally a strong investment in Tampa Bay. The area gets 244 sunny days per year, the federal tax credit covers 30% of installation costs, and Florida offers property tax and sales tax exemptions for solar. The typical payback period is 8-12 years, with 25-year panel warranties providing 13-17 years of essentially free electricity after that.

Does TECO offer any programs to help lower my electric bill?

Yes. TECO Energy offers several programs for residential customers, including a free home energy audit, rebates for high-efficiency AC systems and heat pump water heaters, a budget billing program that averages your costs into equal monthly payments, and a time-of-use rate option that gives you lower rates during off-peak hours. Check with TECO’s website or customer service for current program availability and eligibility requirements, as programs change over time.

How much does a pool add to your electric bill in Florida?

A pool pump typically adds $40-$100 per month to your electric bill, depending on the pump type and run time. Older single-speed pumps running 8-12 hours per day are at the high end. A variable-speed pump running the same hours uses 50-70% less electricity. If you also heat your pool during the cooler months, add another $50-$150 per month from October through March. For more on pool ownership costs, see my pool homes guide for Brandon FL.

Want to Find an Energy-Efficient Home in Tampa Bay?

Electric bills are one of those costs that most buyers don’t think about until after they’ve closed – and by then it’s too late to factor it into the purchase decision. I help my clients evaluate the full cost of homeownership before they make an offer, and that includes understanding what a home is going to cost to cool. Whether you’re looking for a newer, energy-efficient home that keeps your bills low, or you’re evaluating an older home and want to know what upgrades will have the biggest impact, I can help you make a smart decision.
