San Antonio runs on cooling. Summers are long and hot, so AC service is close to a year-round business. Spring can bring hail and heavy rain, which turn into roof, flooding and plumbing calls.
A hard freeze is rare, but when it comes it finds bare pipes. Many local homes sit on concrete slabs, so a slab leak is a common plumbing job, and the water here is hard, which shortens the life of water heaters.
Limestone-lot homes near Alamo Heights, tracts near the bases and newer Hill Country builds all carry different equipment and ages.
In Texas, AC work, plumbing and pest control each fall under a separate state license, so your pages should show the ones you hold and nothing else.
Lead sites can sell one customer to several firms, so independent trades win by naming the area, the job and the license. A click from Boerne is wasted if your only truck is in Stone Oak.
