Reviews
5 orange stars.
Our AC went out today (Sunday) and after calling several places, they were able to come out within 30 minutes of calling. Our tech, Darien was courteous, efficient and solved the problem within 2 hours. It’s insane not to have AC in Tucson so I’m so glad that this business operates 24/7 here! Thank you sooooo much!!!!

There’s a reason for all the 5-star Williamson’s reviews. They tell you what they’re going to do. They do it, and they charge a fair price for doing it. Every person we dealt with at Williamson’s was courteous, knowledgeable, honest, and helpful. They also treat your home with respect, and clean up after themselves.

FAQs

Frequently Asked Questions

What are some common plumbing repairs?

Some of the most common plumbing repairs we handle include leaking faucets, clogged drains, running toilets, damaged pipes, and water heater issues. Many of these problems start small but can lead to water damage or higher utility bills if left unaddressed. Our plumbers diagnose the issue and complete repairs with proper materials and methods to restore reliable performance.

What should I do in case of a plumbing emergency?

If you experience a plumbing emergency, shut off the main water supply if it is safe to do so, then contact a licensed plumber right away. Quick action helps limit water damage and prevents further issues. Our team provides emergency plumbing services to address burst pipes, severe leaks, backups, and other urgent problems when immediate help is needed.

What causes a running toilet?

A running toilet is typically caused by a worn flapper, faulty fill valve, or improper float adjustment. When these components fail, water continues to flow into the tank and bowl rather than shutting off. Ignoring a running toilet can waste significant amounts of water over time. A professional repair restores proper operation and prevents unnecessary water loss.

Why isn’t my air conditioning unit cooling my home effectively?

Poor cooling performance can result from restricted airflow, dirty coils, low refrigerant levels, thermostat issues, or failing components. In Tucson’s heat, even minor problems can quickly affect comfort. Regular maintenance helps prevent many of these issues, but when cooling problems persist, a professional inspection is the best way to identify and correct the underlying cause.

Can I fix plumbing or HVAC issues myself?

Some basic tasks, such as changing air filters or checking visible leaks, are manageable for homeowners. However, most plumbing and HVAC repairs require specialized tools and training. Attempting complex repairs without proper knowledge can worsen the problem or create safety risks.

Unlicensed repairs may also void manufacturer warranties. Licensed HVAC professionals use OEM parts and follow approved repair procedures to maintain warranty validity and ensure safe, reliable operation.

What can I do to extend the life of my plumbing and HVAC systems?

Routine maintenance plays a major role in system longevity. HVAC systems benefit from bi-annual inspections, one before the cooling season and one before the heating season. Plumbing systems should receive annual inspections, along with periodic water heater flushing.

Being mindful of what goes down your drains, addressing small issues early, and avoiding overworking your HVAC system all help reduce wear and extend equipment life.

Are plumbing issues related to hard water?

Yes, hard water can contribute to plumbing problems over time. Mineral buildup can restrict pipes, reduce water heater efficiency, and affect components like valves and fixtures. Professional inspections help identify mineral-related wear early and recommend solutions to protect your system.

When should I replace my HVAC system rather than repair it?

Replacement may be worth considering if your system is older, requires frequent repairs, or no longer meets your comfort needs. A professional evaluation helps compare repair costs, efficiency improvements, and long-term reliability so you can make an informed decision.
