Common Plumbing Problems and Their Fixes
Plumbing issues can range from minor leaks to major system failures. Here are some of the most frequent problems and how they can be resolved.

A dripping faucet may seem harmless, but it can waste hundreds of gallons of water per year, increasing utility bills.
Causes of a Dripping Faucet:
- Worn-out rubber washers or O-rings
- Corroded valve seat or seals

How to Fix It:
- Replace worn washers and O-rings.
- Inspect the valve seat and clean out any mineral buildup.

How to Fix It:
- Use a plunger or drain snake to remove blockages.

Weak water pressure can make daily tasks like showering, washing dishes, and laundry frustrating.
Possible Causes:

- Hidden leaks in the plumbing system

How to Fix It:
- Clean aerators and showerheads to remove debris.

Common HVAC Problems and Their Fixes
A malfunctioning HVAC system can lead to uncomfortable indoor temperatures, high energy bills, and poor air quality. Here’s how to identify and fix common issues.

Unusual sounds like banging, squealing, or rattling often indicate mechanical problems.
Possible Causes:
- Loose or broken components (fans, belts, or motors)
- Ductwork leaks or obstructions
