Already know it is not a DIY fix? TLS Air Conditioning & Insulation offers same-day diagnosis across Tampa Bay and Southwest Florida, with a $125 diagnostic fee credited toward your repair if you move forward. Call (833) 857-7283 or request a free estimate online. Keep reading if you want to narrow down the cause first.
Find the symptom that best matches your home. These are possible causes, not a diagnosis. A TLS technician can check whether the problem starts with the AC system, ductwork, or attic insulation.
A few safe checks can help you describe the problem when booking AC service. Stop if you smell burning, see smoke, or a breaker trips again after one reset.
Set the thermostat to Cool, choose a temperature below the room reading, and set the fan to Auto. Replace weak thermostat batteries and check the indoor and outdoor breakers. If the AC still will not start, a full condensate drain pan may have triggered its float switch.
Replace a dirty air filter and make sure supply vents and return grilles are clear. Weak airflow can point to a blocked filter, blower problem, or damaged ductwork. Airflow that feels normal but blows warm needs a closer AC diagnosis.
From a safe distance, check for leaves or plants blocking airflow. Note whether the outdoor fan runs while the indoor blower is on. Do not open the service panel or touch electrical parts. Tell the TLS technician what you observed so they can test the cause.
A working air conditioner may struggle if heat enters through the attic or cooled air escapes through the ducts. In Tampa Bay and Southwest Florida, check the whole cooling system before deciding the AC needs replacing.
Thin or damaged attic insulation can add heat to upstairs rooms. Leaky, crushed, or disconnected ducts can leave some rooms warm even when the air at other vents feels cold. TLS can check insulation levels, duct condition, and airflow alongside AC performance.
A dirty filter, duct leaks, insulation gaps, or aging equipment can increase cooling costs without an obvious breakdown. Water stains or a musty smell may point to moisture near the AC, ducts, or attic insulation. Find the moisture source before replacing affected material.
If you find unfamiliar loose insulation in an older attic, do not handle it. Some vermiculite insulation may contain asbestos. Have the material assessed by a qualified specialist before work disturbs it.
If you smell burning, see smoke, or the breaker keeps tripping after you reset it once, shut the system off at the breaker and call. Don’t keep resetting it.
TLS Air Conditioning and Insulation has cooled and protected Tampa Bay and Southwest Florida homes for 11 years. Seth Hoerig founded the company as a family-owned operation, and we still run it that way, with our own trained technicians and no subcontractors on any job.
We diagnose AC problems correctly the first time, and that is what sets us apart. Our technicians walk into a Florida attic in July and know within minutes whether a symptom traces to the AC, the ductwork, or the insulation around it, a distinction most homeowners cannot make alone and one most companies skip entirely.
We provide troubleshooting and repair service across Tampa Bay and Southwest Florida from seven offices: St. Petersburg, Tampa, Sarasota, Venice, Punta Gorda, North Port, and Pinellas Park. Same-day diagnosis is standard across that territory, not an upsell.
We hold Florida licenses CAC1822364 for HVAC work and EC13016589 for electrical work, and we back every diagnosis with a $125 fee that gets credited straight to your repair. That is how we earn the call before we earn the job.
If your symptom points to something beyond a filter change or a breaker reset, here is where we can help next:
AC repair, for the issues in the symptom table above that need a technician
AC installation, when repair no longer makes sense for your system’s age or repair history
Ductless mini split installation, for garages and rooms without existing ductwork
Duct sealing, when the diagnosis points to heat gain in the ductwork rather than the AC unit
Attic insulation, when the cause traces back to the attic instead of the AC
Full AC services overview, if you are not sure which service fits your symptom
Our technician checks the system, explains what failed, and shows you the findings before recommending a repair. That may include a test reading or photo when it helps clarify the problem.
With seven offices across Tampa Bay and Southwest Florida, we offer same-day appointments when available. Before approved work begins, you receive a written, fixed price.
Some comfort problems start in the ductwork or attic rather than the AC equipment. TLS can assess all three, so you get a clear recommendation for the problem affecting your home.
Call or book online and describe the symptoms. We offer same-day appointments when available.
A technician checks the AC and tests the likely cause. We also assess ductwork or attic insulation when the symptoms point there.
We show you the relevant test reading, photo, or failed part and discuss your repair options.
We provide a written, fixed price before repair work begins.
Many common repairs finish in one visit. We test the system afterward to confirm it operates properly.

A hot room, water leak, or AC that will not start can have different causes. Let TLS check the system, explain the findings, and give you a written price before you approve the repair.
If air is coming out but it’s not cold, the problem is usually refrigerant, the compressor, or a dirty coil. If barely any air is coming out at all, it’s more likely the filter, the blower, or the ducts. One Florida addition worth checking: if the air at the register is genuinely cold but the house still won’t cool, the equipment may be fine, and the attic may be adding more load than it can keep up with.
Most often a failed capacitor or contactor, occasionally a seized motor. One detail that narrows it down: is the indoor blower still running while the outdoor unit sits completely silent? That pattern points at the electrical components rather than the motor itself. Do not open the service panel. The capacitor holds a charge even after the power is off.
In Florida this is almost always a clogged condensate drain line, since the humidity means the system produces a lot of water and the line stays damp enough for biological growth to build up. A float switch is supposed to shut the system down before the pan overflows. If yours didn’t, that’s a separate fault to check.
Usually moisture sitting on the evaporator coil or in the drain pan, which is a Florida standard rather than a Florida exception. A musty smell can also come from wet attic insulation venting into the living space, and that’s a different trade entirely. One test: does the smell show up only when the system is running?
This is the question the whole page exists to answer, so here’s the direct answer: usually it’s neither a broken AC nor a broken duct, it’s load. A Department of Energy study measured an attic dropping from R-38 to R-30 adding 5,100 Btu/h of cooling load, close to a full additional ton. The common response to this symptom is a quote for a bigger AC, but ACCA guidance holds that oversizing is worse than undersizing where humidity control matters. Have the attic checked before you accept a quote for a larger system.
A system working exactly as designed against a leaky attic or leaky ducts will produce a rising bill with no fault code. Check the causes cheapest first: the filter, then duct leakage, then attic R-value, then the equipment’s age. In a Florida Solar Energy Center study, repairing leaky ducts alone cut cooling energy use by 17.2% across 46 homes.
Check the indoor and outdoor breakers, the outdoor disconnect switch, and whether the thermostat lost its schedule or its batteries during the outage. Some systems have a built-in delay of several minutes before the compressor restarts after power returns, so give it a few minutes before assuming something’s wrong. If the breaker trips repeatedly after an outage, stop resetting it and call.
Yes to the thermostat, the breaker, the filter, clearing debris from the outdoor unit, and making sure vents are open. No to anything behind the service panel, refrigerant, wiring, and the compressor. The reason: capacitors hold a charge even after the power is off, and refrigerant handling is federally regulated under EPA rules. If you smell burning, see smoke, or the breaker keeps tripping, shut it off at the breaker and call.
