Plumbing Troubleshooting & DIY Fixes

Leaky Faucet
A dripping faucet is one of the most common plumbing issues we see in Lubbock homes. It’s often caused by a loose handle or worn internal parts.
DIY fix: Turn off the water supply and gently tighten the handle or visible fittings. If the drip continues, stop and call a professional.

Garbage Disposal Smells
Odors usually come from food buildup inside the disposal, especially after heavy use.
DIY fix: Run cold water while grinding ice cubes and a few citrus peels to help clean and freshen the unit.

Low Water Pressure
Low water pressure is often caused by mineral buildup in faucets and showerheads, which is common in West Texas.
DIY fix: Remove the faucet aerator or showerhead and soak it in vinegar to dissolve debris, then rinse and reinstall.

Slow Draining in Sinks or Tubs
Slow drains are usually caused by hair, soap residue, or everyday buildup.
DIY fix: Use a drain stopper or small plastic drain snake to remove visible debris, avoid chemical drain cleaners.
Heating Troubleshooting & DIY Fixes
Furnace Not Turning On
When the temperature drops in Lubbock, a furnace that won’t start can be stressful. Sometimes the issue is something simple.
DIY fix: Check that the thermostat is set to “heat” and that the furnace switch and breaker are on.
Weak or No Airflow
Poor airflow often points to a clogged air filter or blocked vents.
DIY fix: Replace the furnace air filter and make sure vents are open and unobstructed.
Furnace Blowing Cold Air
This can happen if the system hasn’t fully warmed up or the settings aren’t quite right.
DIY fix: Confirm the thermostat is set to “auto” instead of “on” to allow proper heating cycles.
Strange
Noises
Rattling or banging sounds can be unsettling, especially during cold nights.
DIY fix: Carefully check for and tighten any loose exterior panels, do not open internal components.
Air Conditioning Troubleshooting & DIY Fixes

AC Not Cooling
When Lubbock summer heat hits, an AC that isn’t cooling properly is more than uncomfortable.
DIY fix: Make sure the thermostat is set to “cool” and replace the air filter if it’s dirty.

Weak Airflow
Limited airflow can make your home feel warmer than it should.
DIY fix: Check vents throughout the home and remove any furniture or blockages.

AC Leaking Water
Water leaks often come from a clogged condensate drain line.
DIY fix: Turn off the system and gently clear visible debris from the drain line opening.

Strange AC Noises
Buzzing or rattling noises may come from debris around the outdoor unit, a common issue in windy West Texas conditions.
DIY fix: Turn off power and clear leaves or debris from around the outdoor AC unit.
DIY vs. Professional Help
At Lowery, DIY troubleshooting is a great first step for small issues. These simple checks can save time and help you understand what’s happening in your home.
That said, knowing when to stop is just as important. If a task feels unsafe, requires special tools, or doesn’t solve the problem, continuing could lead to bigger and more expensive repairs. Professional service ensures the issue is fixed correctly and protects your home, your comfort, and your equipment.
