Why is my water bill suddenly so high?

A spike often indicates a hidden leak, running toilet, slab leak, or irrigation issue. A licensed plumber can locate and fix the source before damage worsens.

What are signs of a slab leak in my home?

Warning signs include unexplained high water bills, warm spots on floors, low water pressure, or the sound of running water. Slab leaks should be addressed immediately.

How long do water heaters last in Texas?

Traditional tank water heaters typically last 8–12 years in North Texas due to hard water and heavy use. Tankless systems may last longer with proper maintenance.

How often should AC be serviced in Texas?

In North Texas, AC systems should be professionally serviced twice a year—once in the spring and once in the fall. Regular maintenance helps improve efficiency and extends the life of your unit.

Is it normal for my AC to run all day in Dallas heat?

During peak summer temperatures, it’s normal for AC systems to run longer. However, constant operation may indicate undersized equipment, insulation issues, or mechanical problems that should be checked.
