What we do

Built for Florida — not just
the brochure version of it.

95° afternoons. Three-hour thunderstorms. Salt air on the coast and humidity that won’t quit. Our crew has seen all of it — and built service plans that handle the worst of it without padding the bill.

Most calls

AC repair & replacement

Capacitors at 2am, full-system replacements that last fifteen years, and everything in between. Every brand, written quote first.

  • Capacitor & compressor repair
  • Refrigerant leak detection (R-410A / R-32)
  • SEER2 high-efficiency installs
See pricing
Heating

Heating & furnaces

Tampa gets cold a dozen nights a year — but when it does, you want heat that works. Heat pumps, gas furnaces, electric backup.

  • Furnace repair & safety check
  • Heat pump installs & service
  • CO & combustion analysis on every visit
See pricing
Air quality

Indoor air quality

Florida humidity is half a comfort problem and half a mold problem. We fix both with whole-home filtration, UV-C, and dehumidifiers.

  • MERV-13 filter cabinets
  • UV-C germicidal lamps
  • Whole-home dehumidifiers
See pricing
Smart home

Smart thermostats & zoning

A Nest installed wrong will freeze your evaporator coil. Installed right, it pays for itself in 18 months of power bills.

  • Nest, Ecobee, Honeywell pro installs
  • Two-zone damper systems
  • C-wire adapters & sensors

Why Thermalux

Family-owned, flat-rate,
and a little stubborn about it.

Marcus and Linda Hayes started Thermalux out of their garage in Seminole Heights in 2012, because they were tired of watching neighbors get gouged on Sunday-afternoon AC repairs. Ten years and five trucks later, we still won’t pay our techs commission — nobody on our crew ever benefits from selling you something you don’t need.

Flat-rate quoted in writing — no “time & materials” surprises
Every tech is background-checked, drug-tested, NATE-certified
Zero commission. Zero scripted upsells. Ever.
If we can’t fix it right, the service call is free

Upfront price

Signed in writing before any wrench moves. No “and one more thing…” at the end.

Same-day fixes

Most calls before 2pm get a tech on-site the same afternoon — often faster.

10-yr warranty

New installs covered ten full years. Parts, labor, refrigerant — no asterisks.

Fixed or it’s free

If we can’t diagnose and fix your system properly, you don’t pay for the visit.

My AC died on a Saturday afternoon — 94 outside, kids melting. Called at 2pm, tech was at the door by 3:30 with cold air blowing by 4:15. Fair price, no upsell. These guys are our HVAC company for life.

Got three quotes for a full system replacement. Thermalux was the middle bid — but the only one who explained sizing, SEER ratings, and warranty terms in plain English. Install was clean, on time, and the new unit cut our July bill by 31%.

I’ve had the Comfort Club plan for two years. They show up on time twice a year, catch things before they break, and never try to sell me what I don’t need. I’ve spent $0 on emergency repairs since signing up.

Installed a whole-home dehumidifier and UV-C system for us. My wife’s summer allergies were brutal — she’s been off her allergy meds for three months. Tech was patient with every dumb question I asked.

They quoted me $215 for a capacitor. Another company tried to sell me a $9,400 new system the day before for the same problem. Saved me roughly $9,200. Honest crew.

First HVAC company that didn’t talk down to me. Marcus walked through every option, sent the quote by text, didn’t pressure me when I said I wanted to think on it. We hired them a week later.
