A depot town's housing stock, a century wide
Old Town Tomball grew up around the railroad depot, and its blocks still hold the spread: early-1900s cottages, mid-century one-stories, and newer infill side by side. Many of the oldest homes are pier-and-beam with retrofit ductwork — or no ductwork at all.
That range means the honest answer is different house to house. A shiplap cottage may be best served by ductless mini-splits and an electrical safety pass; a 1960s ranch may need duct replacement before any new condenser makes sense. We diagnose before we quote, every time.
Homes that never had ducts
Forcing retrofit ductwork into a small cottage costs ceiling height and efficiency. Ductless mini-splits condition these homes room by room without butchering the structure.
Century-spanning electrical
From legacy wiring in the oldest homes to 1960s panels in the ranches, electrical safety is the first checkpoint. Our Master Electrician inspects and remediates with City of Tomball permits.
Pier-and-beam comfort loss
Raised floors lose conditioned air downward. Underfloor insulation and sealing recover comfort the equipment can't deliver alone.

Old Town Tomball questions we hear the most
My Old Town Tomball cottage has no ducts — what are my options?
Ductless mini-splits are usually the honest answer: room-by-room conditioning without sacrificing ceiling height or cutting up a historic structure. Qualifying units also earn CenterPoint incentives.
Is the wiring in my older Tomball home safe for new equipment?
That's the first thing to verify. Our Master Electrician inspects the panel and branch circuits before any new mechanical load is added, and remediates with City of Tomball permits.
Who issues permits in Old Town Tomball?
The City of Tomball — this is inside the city limits, unlike the unincorporated communities nearby. Avatex handles the city paperwork and inspections.
Why is my pier-and-beam home hard to keep comfortable?
Raised floors lose conditioned air downward and pull in outside air at the edges. Underfloor insulation and sealing usually recover more comfort per dollar than an equipment change.
