Common Questions

My AC stopped working during a Katy heatwave. How quickly can you help?

We understand how urgent an AC failure is in our Texas heat. For Katy residents facing no cooling or poor airflow, we prioritize emergency service calls to diagnose the issue promptly. Our team is experienced in rapid troubleshooting of common local problems like capacitor failures, refrigerant leaks, or clogged condensate drains to restore your comfort as soon as possible.

Do you handle both electrical panel upgrades and EV charger installation?

Yes, we provide a complete electrical service. Many Katy homes with older panels need an upgrade to safely support new additions like an Electric Vehicle charging station. We can assess your current panel, perform any necessary repairs or a full installation of a new unit, and then properly wire and install your EV charger, ensuring everything is up to code and functions safely.

What plumbing issues do you commonly repair for homeowners?

We frequently assist Katy homeowners with repairs for leaky faucets, running toilets, clogged or slow drains, and garbage disposal jams. We also handle more significant projects like water heater repairs or replacements, sewer line issues, and sump pump failures. Our approach is to diagnose the root cause and provide a lasting repair, not just a quick fix.
