Castle Air Conditioning & Heating is based in Fulshear and covers the Greater Houston metro area — west through Katy, Richmond and Sugar Land, across the inner loop from Memorial and the Heights down to Bellaire and West University, and southeast to Pearland, Clear Lake, Webster, Seabrook and Galveston. Call or text (713) 667-7606 and we will tell you honestly whether you are inside the area.

Find your area

We are based in Fulshear. The area runs west to Katy and Richmond, across the inner loop, and southeast to the Bay Area and Galveston — a little over 70 miles end to end. Everything listed here is somewhere we actually run calls, not a list padded out to look bigger.

These are the places we are in most weeks. Each one has its own page covering what actually changes locally — the age of the housing, the systems we see most, and how a call out there tends to go.

Everywhere else we cover

We are out here just as often, with the same technicians, the same trucks and the same chance of a same-day appointment when you call early:

  • Sugar Land
  • Memorial
  • Southwest Houston
  • Meyerland
  • Galleria
  • River Oaks
  • West University
  • Rice Village
  • Midtown
  • Central Houston
  • Pearland
  • Clear Lake
  • Webster
  • Houston Bay Area

Your address changes the job more than you would think

Houston is not one climate and it is certainly not one kind of house, so the same symptom gets a different diagnosis depending on where you live.

On the coast — Galveston, Seabrook, Clear Lake, Webster — salt in the air corrodes outdoor condenser coils and cabinets far faster than it does inland. A unit that would be middle-aged in Katy can be visibly eaten through down there. Coastal systems need rinsing and inspecting more often, and coil condition is the first thing we look at.

Inside the loop — the Heights, River Oaks, Bellaire, West University, Rice Village, Meyerland — the housing is older and so is a lot of the ductwork. Undersized returns, attic runs that were never sealed properly and systems squeezed into spaces they were never designed for are routine. Replacing the equipment without looking at the duct it breathes through usually disappoints people.

Out west — Fulshear, Cross Creek Ranch, Katy, Richmond, Sugar Land — the homes are newer and mostly two storeys, and the complaint we hear most is that upstairs will not keep up in August. That is usually a balance and airflow problem rather than a dying system.

What we do across the whole area

Wherever you are on that list, you get the same services: AC service and repair, emergency and same-day repair, preventative maintenance, installation and replacement, heating service and repair, heat pumps and ductless mini-splits. We have been doing it since 1975, we are an American Standard Customer Care Dealer, and we are licensed under TACLA #00051749C.

We quote on the house rather than from a price list, because sizing, ductwork and access change the job. Financing is available subject to approved credit.
