AC Installation in Tequesta, FL: A Homeowner's Guide to Getting It Right

Tequesta's proximity to the Atlantic coast and the Loxahatchee River means humidity levels routinely stay above 70 to 80 percent for much of the year. That's not just uncomfortable — it affects how your air conditioning system must work to keep your home livable. In humid subtropical climates like South Florida, an oversized AC unit is nearly as problematic as an undersized one. A system that's too large will cool your home quickly but shut off before it can properly dehumidify the air, leaving you with that clammy, muggy feeling even when the thermostat reads 75°F.

Proper Manual J load calculations are the standard method HVAC contractors use to determine the correct system size in BTUs for your specific home. This calculation takes into account your home's square footage, ceiling height, insulation values, window placement and type, local climate data, and even the number of people typically in the house. In Tequesta, where summer design temperatures and high latent heat loads from moisture are both significant, skipping or shortcutting this step is a red flag.

For most single-story homes in the 1,500 to 2,500 square foot range common in Tequesta's Jupiter Inlet Colony and surrounding neighborhoods, systems typically fall in the 3-ton to 4-ton range — but that's not a rule. Every home is different, and your quote should reflect a calculated recommendation, not a guess based solely on square footage.

As of January 2023, the Department of Energy updated efficiency standards for residential air conditioners. Systems sold in the Southeast U.S., including all of Florida, must now meet a minimum SEER2 rating of 15.2 for single-stage split systems. SEER2 is a revised testing metric that more accurately reflects real-world efficiency than the older SEER scale, so you'll see slightly different numbers when comparing older equipment to newer units.

For Tequesta homeowners served by Florida Power & Light (FPL), efficiency matters beyond just your monthly utility bill. FPL periodically offers rebate programs for qualifying high-efficiency equipment — typically systems reaching certain SEER2 thresholds above the minimum. These programs change, so confirming current availability directly with FPL or through your contractor at the time of installation is the right approach. We can't promise specific rebate values here, but it's worth asking about during your intake process.

In practical terms, a system in the 16 to 18 SEER2 range tends to hit a reasonable sweet spot for Tequesta's climate, balancing upfront equipment cost against long-term energy savings. Variable-speed or two-stage compressor systems in this range also offer better dehumidification — a meaningful benefit in a coastal Florida community where humidity control is nearly as important as temperature control.

In Palm Beach County, AC replacement is a permitted activity. This means your contractor must pull a permit before installation begins, and a county inspector must sign off on the completed work. This isn't a bureaucratic inconvenience — it's a safeguard that protects you as a homeowner. A permitted and inspected installation means the work meets Florida Building Code standards, and it protects your home's resale value. An unpermitted AC installation discovered during a home sale can create serious legal and financial complications.

The permit process in Palm Beach County typically involves the contractor submitting plans or equipment data to the county building department, paying permit fees, and scheduling an inspection after installation is complete. For straightforward system replacements (same tonnage, same location), the timeline from permit application to inspection approval often runs one to three weeks, though it can vary based on the county's current workload.

As a homeowner, you have every right to ask your contractor: 'Will you be pulling a Palm Beach County permit for this installation?' If the answer is anything other than a clear yes, that's a serious concern. Reputable contractors in Tequesta and the broader Jupiter area build permit coordination into their standard workflow. Make sure any quote you review includes this step, and ask for the permit number once it's issued.

Many Tequesta homes, particularly those built in the 1970s through the 1990s, have ductwork that was sized for older, less efficient systems — or that has simply degraded over decades in Florida's heat and humidity. Duct leakage is one of the most common culprits behind high energy bills and rooms that never seem to cool properly, and it's often invisible without a proper inspection.

Before or during your AC installation, a quality contractor should assess your existing duct system. Key questions include whether the ducts are properly sealed at joints, whether the duct sizing matches the new system's airflow requirements, and whether insulation on ducts running through the attic is intact. Attics in Tequesta can reach 140°F or more in the summer — poorly insulated ducts running through that environment are giving away a significant portion of your cooling capacity before it ever reaches your living space.

If your ducts need work, that's important information to have before finalizing a system selection. A new high-efficiency system paired with leaky or undersized ductwork won't perform the way the specifications suggest. Some contractors offer duct testing using a blower door or duct pressurization test to quantify leakage — this is worth asking about, especially in older homes.

Walking into a quote review without the right information puts you at a disadvantage. Here's what to have on hand before you evaluate any AC installation proposal for your Tequesta home:

**Your home's square footage and age.** This gives a contractor a starting point for load calculations and helps flag whether your existing ductwork is likely to need evaluation.

**Your current system's age, tonnage, and model if available.** Usually found on the outdoor unit's data plate. This helps determine whether the new system is being sized appropriately or just matched to the old one without analysis.

**Recent FPL bills.** Utility usage history tells a lot about how hard your current system is working. Significant increases in kWh consumption over prior years can point to efficiency loss.

**Your home's insulation situation.** Especially relevant in attic spaces. Poor insulation dramatically increases the load on your AC and affects which system size and efficiency level makes sense.

**Any comfort complaints.** Rooms that are always too warm, humidity issues, or excessive noise all provide clues about whether the current system or ductwork is the root cause — and what a replacement needs to address.

Having this information ready doesn't just help contractors give you a more accurate proposal — it helps you evaluate whether the proposals you receive are genuinely tailored to your home or just templated estimates.

Tequesta is served by contractors based in Jupiter, Palm Beach Gardens, and throughout northern Palm Beach County. The local market is competitive, which is good for homeowners — but it also means the range of quality varies. A few things to verify before committing:

First, confirm the contractor holds a current Florida State Certified or Registered Mechanical Contractor license. You can verify this quickly on the Florida Department of Business and Professional Regulation (DBPR) website. This license is separate from a general contractor's license and specific to HVAC work.

Second, confirm they carry both general liability insurance and workers' compensation coverage. In Florida, workers' comp requirements for contractors are strict, and you don't want exposure if someone is injured on your property.

Third, ask specifically about their experience with Palm Beach County permitting. Contractors who work regularly in this county will know the local inspection process and build it into their timeline without surprises.

Finally, ask about manufacturer relationships. Many manufacturers have authorized dealer programs that come with extended warranty options — sometimes 10-year parts warranties that require professional installation and registration. A contractor who is an authorized dealer for the brand they're proposing can often offer better warranty support than one who is not.
