They worked on my AC and were very helpful and friendly. Definitely recommend them!!
Largo’s housing stock is heavily concentrated in the 1970s and 1980s, meaning the city has one of the highest densities of aging AC systems in the Tampa Bay area. Many homes are single-story concrete block construction on slab foundations, which simplifies some aspects of installation but often comes with ductwork embedded in tight attic spaces.

Largo also has a significant number of manufactured and mobile homes that require specialized AC installation approaches different from traditional site-built homes. Retirement community residents in Largo are frequently making their final system replacement and want equipment that will last reliably for the long term.

Largo AC installations benefit from the relatively uniform housing stock, which means our technicians know exactly what to expect in most homes. Duke Energy serves all of Largo, and high-efficiency system upgrades can meaningfully reduce monthly bills for retirees on fixed incomes. The concrete block, slab-on-grade construction common in Largo makes for durable homes, but the ductwork in the attic is often the weak link after 40-plus years of Florida heat exposure.

A Goodman GSXC18 single-stage 15.2 SEER2 with proper ACCA Manual J sizing runs $5,800 to $6,200 installed in a typical 1,600 square foot Largo ranch home. Annual cooling cost on Duke Energy Florida rates runs about $1,050. Lifespan: 10 to 12 years on inland exposure. Total 15-year cost including a likely partial replacement at year 11: roughly $23,800.
A Daikin DZ20VC variable-speed 20.5 SEER2 with the same Manual J sizing runs $11,400 to $12,800 installed. Annual cooling cost drops to about $680 thanks to inverter modulation that runs at 30 to 100 percent output continuously instead of cycling on and off. Lifespan: 14 to 16 years. Total 15-year cost: roughly $21,800. The Daikin pays back its premium in 9 to 11 years on energy alone, plus delivers humidity control that matters for the older Largo ranch homes where original windows leak Gulf-influenced humidity straight into conditioned space. For seasonal residents or rental properties, Goodman is the practical choice.
Largo housing stock runs from 1960s 1,200 square foot ranch homes to 2010s 2,400 square foot townhomes, each with different load characteristics. Generic ton-per-square-foot rules under-size or over-size the equipment by 20 to 35 percent depending on era. We run a full ACCA Manual J on every Largo install that accounts for actual window orientation, attic R-value (often R-11 on the original 1960s builds vs R-30 on newer construction), and infiltration measured at the front door. Right-sized equipment runs longer cycles, pulls more humidity, and lasts longer through Pinellas summers.
Full Manual J load calc included free on every install estimate.
Original Largo ductwork in the 1960s and 1970s ranch homes is now 50 plus years old. Sheet-metal trunks have settled, gaskets have shrunk at boot connections, and supply runs often leak 25 to 35 percent of conditioned air into the attic plenum. Installing a new high-efficiency Daikin or Goodman on this ductwork wastes 30 percent of the efficiency rating. We perform a static pressure test plus a smoke-pencil leak check on every Largo install and quote duct repair separately. Newer 55-plus townhomes typically have intact R-6 flex that may only need minor sealing at boot connections.
Static pressure + smoke-pencil duct check on every install.
Most Largo homes have air handlers in unconditioned attic space that hit 130 to 140 degrees in summer. This shortens motor and capacitor life by 30 to 40 percent compared to closet-mounted installs. We recommend either upgrading attic insulation around the air handler enclosure or specifying enhanced-spec motors and capacitors built for high ambient temperatures. We also include an overflow safety switch and a redundant condensate drain pan on every Largo install: a clogged primary drain in an attic unit causes $4,000 to $8,000 in ceiling drywall damage when the secondary overflow is not installed.
Attic insulation review plus overflow safety on every Largo install.

Effective January 1, 2026, every new residential AC system manufactured in the United States ships with R-454B refrigerant instead of R-410A. R-454B has 78 percent lower global warming potential and an A2L mildly flammable classification, which requires updated installer training, leak detection sensors on indoor air handlers, and refrigerant line set diameters sized to the new specification. For Largo homeowners weighing whether to repair a 12-year-old R-410A system or replace now, the new R-454B equipment ships with 12-year compressor warranties from Daikin and 10-year parts from Goodman. R-410A refrigerant cost will climb sharply through 2026 and beyond. Florida South minimum SEER2 is 14.3. Duke Energy rebates and IRA HEEHRA credits up to $2,000 on qualifying heat pump versions stack with our pricing.

Largo AC installations start at $6,500 for a Goodman Value system in a standard concrete block home. Because most Largo homes are single-story and between 1,000 and 1,800 square feet, system sizes typically range from 2 to 3.5 tons, keeping equipment costs moderate. Manufactured home installations have different pricing structures and typically start around $5,500 to $7,500 depending on the configuration. For site-built homes, most Largo homeowners invest between $6,500 and $11,000, choosing between Goodman and Daikin based on their budget and efficiency priorities. Ductwork replacement, if needed, is the most common factor that adds to the base installation cost in this area.
A: AC sizing depends on your home’s square footage, insulation, window count, and layout. A rough guide is 1 ton per 500 square feet in Florida, but that varies. In Largo, where most homes are concrete block with flat or low-slope roofs built in the 1970s to 1980s, insulation quality and ductwork condition are key factors. An undersized unit will run constantly and never cool properly. An oversized unit will short-cycle and create humidity problems. We perform a Manual J load calculation to determine the exact size your Largo home needs.
A: Most standard AC installations in Largo are completed in one day, typically 6 to 10 hours. concrete block with flat or low-slope roofs homes from the 1970s to 1980s usually have straightforward access to the air handler and ductwork. If we are replacing ductwork or moving the air handler, it can take a second day. We schedule the work to minimize disruption and always clean up before we leave.
A: We install Goodman as our Value and Premium tier and Daikin as our Elite tier. Both brands are well-suited for Largo’s climate and concrete block with flat or low-slope roofs homes. Goodman offers excellent reliability at a great price point, while Daikin provides top-tier efficiency that pays for itself through lower Duke Energy bills. We help Largo homeowners choose the best match for their budget and home layout.
A: Yes. In Florida, your AC runs 8 to 10 months per year. Upgrading from a 10 SEER unit to a 16 SEER2 unit can cut your cooling costs by 30 to 40 percent. For a typical Largo home powered by Duke Energy, that translates to $600 to $1,200 in annual savings. concrete block with flat or low-slope roofs homes from the 1970s to 1980s often have older, less efficient systems, making the upgrade impact even bigger. Most high-efficiency systems pay for themselves within 5 to 7 years.
A: Yes, we offer flexible financing for Largo homeowners. Plans include 0% interest for qualified buyers, low monthly payments, and terms up to 72 months. We work with multiple lenders so we can find an option that fits your budget. No one in Largo should suffer through a Florida summer because of upfront costs.
A: Use the $5,000 rule: multiply the age of your system by the repair cost. If it exceeds $5,000, replace it. In Largo, where systems from the 1970s to 1980s are now 15-25 years old, many homeowners are hitting that threshold. Also consider that older units often use R-22 refrigerant, which is phased out and expensive to recharge. A new system will lower your Duke Energy bill and come with a full manufacturer warranty.
A: SEER2 measures how efficiently an AC converts electricity into cooling. Higher SEER2 means lower operating costs. The minimum for new installations in Florida is 15 SEER2. We recommend 16 SEER2 or higher for Largo homes because the energy savings are significant given Florida’s long cooling season. Largo homeowners on Duke Energy often see the biggest bill reduction from an efficiency upgrade.
A: Yes, AC installations in Largo require a Pinellas County building permit and inspection. We handle all the permitting paperwork as part of our installation service. Our license (CAC1819196) is current and in good standing with the state of Florida. Skipping the permit can void your warranty and create problems when you sell your home.
A: A properly installed and maintained AC system in Florida typically lasts 12 to 18 years. Largo’s heat, humidity, and inland heat and dust are hard on equipment, so regular maintenance is critical. We offer maintenance plans that include two tune-ups per year, priority scheduling, and discounts on repairs to help your new system last as long as possible.
A: Yes, we serve every Largo neighborhood across ZIPs 33770, 33771, 33773, 33774, and 33778, including Belleair Bluffs, Bardmoor, West Bay, and Belleair Country Estates, plus the streets near Largo Central Park, Heritage Village, and the Florida Botanical Gardens. Average response time from our Tampa shop is about 45 minutes via Veterans Expressway south to Ulmerton Road west.
A: Same-day full installation is rare because Pinellas County requires a mechanical permit and we want the load calc and ductwork check done right before equipment is ordered. Same-day FREE diagnostic estimate is standard. Most Largo full installs schedule within 5 to 7 days once the permit clears. For an emergency no-cool situation we can often stabilize with a temporary repair while the new install is staged.
A: Probably not without repair. Original Largo ductwork in the 1960s and 1970s ranch homes is now 50 plus years old with sheet-metal trunks that have settled, shrunk gaskets, and supply runs leaking 25 to 35 percent of conditioned air into the attic. Installing a new high-efficiency Daikin or Goodman on this ductwork wastes 30 percent of the efficiency rating. We perform a static pressure test plus a smoke-pencil leak check on every install and quote duct repair separately so you see the full picture before equipment is ordered.
A: Yes. Pinellas County requires a mechanical permit on any AC install. We pull the permit at the Pinellas building department, schedule the inspection, and meet the inspector. We honor Goodman, Daikin, Carrier, Lennox, and Trane manufacturer warranties when we install or service the equipment, plus a 1-year parts and labor warranty on every install.
A: Yes. The in-home estimate is genuinely FREE in Largo. No diagnostic fee, no service-call fee for AC installation estimates. The $279 minimum applies only to APPROVED repair labor on existing systems, not new install estimates. If you decide not to proceed, you owe nothing.
