The People Behind the Work

Lakeland housing runs from 1950s and 60s concrete-block ranches on the south side to 1980s slab-on-grade subdivisions to the newer stucco builds out toward County Line Road. The block houses matter most to us. A lot of them started with window units and got central air added later, and the return path almost never got sized correctly when that happened. One undersized central return in a hallway ceiling, a filter grille choking on static, and the system makes up the difference by pulling attic and wall-cavity air through every gap in the return chase. That is how insulation fiber and raw attic dust end up in a system that has a clean filter in it. The newer subdivisions have their own pattern: insulated flex run over vented trusses, boots that were never sealed to the ceiling drywall, and vapor jackets torn by a staple or pinched flat by a strap.

Central Florida interior, Polk and east Hillsborough counties, runs air conditioning close to continuously from March into November, so duct systems here log far more operating hours than in most of the country. Attic temperatures over vented trusses reach 120-140F in summer while supply air is in the 50s, so insulated flex duct and fiberglass ductboard plenums sit at a permanent condensation risk anywhere the vapor jacket is torn, a strap has pinched the liner, or a boot is unsealed at the ceiling drywall. The pattern across this region is microbial growth at the air handler and first few feet of supply, dust mud on wet duct interiors, and musty odor the first hour of operation in the morning. Add agricultural and construction loads: Plant City strawberry fields and plant nurseries, Polk phosphate and sand haul roads, citrus grove dust, oak and bahia grass pollen in February-May, and heavy summer mold spore counts. Most of our calls start with one of three complaints: morning smell, dust settling back on furniture within a day of cleaning, or a room that never keeps up.

On site, the crew connects a truck-mounted vacuum to the trunk near the air handler and puts the system under negative pressure before anything else happens. Every register and return gets sealed off so the airflow pulls in one direction. Then we work the runs with rotating brushes and compressed-air whips, supply side and return side, and pull the blower wheel and evaporator area for inspection. We open the plenum where we need to see it. We photograph before and after so you are not taking our word for it. We work on Carrier, Trane, Lennox, Goodman, Rheem and American Standard equipment, and on both metal trunk and flex systems. If we get in there and the ducts are clean, we say so and we do not clean them. That happens often enough on houses under ten years old. Sometimes the real fix is the filter and how often it gets changed, or sealing leaking boots and return chases so the system stops drinking attic air, or clearing a loaded evaporator coil that is the actual source of the odor. On cost: the number moves with how many supply runs you have, whether the air handler is in a crawl-tight attic or a garage closet, whether the system is flex or sheet metal, and whether we find microbial growth that needs treatment beyond mechanical cleaning. A 2,400-square-foot house with eighteen runs and an attic handler is a different day than a three-ton system in a utility room.
