Introduction
When temperatures in Florence, AL drop below freezing, both your plumbing and heating system are put to the test. Burst pipes, frozen water lines, and stressed furnaces are all common winter emergencies in North Alabama. The good news? With preparation and awareness, most cold-weather damage can be avoided.
At BTI Plumbing & HVAC, we help Shoals-area homeowners winterize their homes and keep heat flowing through the coldest nights. Here’s what happens when extreme cold hits—and what you can do to protect your home.
1. How Freezing Temperatures Affect Your Plumbing
When water inside your pipes freezes, it expands by nearly 9%. That expansion can create enormous pressure inside the pipe—often enough to crack or burst it.
At highest risk:
- Outdoor spigots and hose bibs
- Uninsulated pipes in attics, basements, or crawlspaces
- Pipes along exterior walls
Prevention tips:
- Disconnect garden hoses and install insulated faucet covers.
- Open cabinet doors under sinks to let warm air reach pipes.
- Wrap exposed plumbing with pipe insulation or heat tape.
- Let faucets drip slightly overnight when temperatures are below 25°F.
Why it matters locally: Florence’s fluctuating winter temperatures cause freezing, thawing, and refreezing cycles—making older plumbing systems especially vulnerable.
2. Stress on Older Furnaces and Heating Systems
Just like your pipes, your furnace works overtime during extreme cold. Constant operation puts strain on older or poorly maintained units, often leading to system shutdowns or cracked heat exchangers.
Signs your heating system is under stress:
- Uneven heating or weak airflow
- Strange noises (rattling, banging, or whistling)
- Higher energy bills without improved comfort
How to prevent furnace failure:
- Replace air filters monthly during heavy use.
- Keep vents unblocked by furniture or curtains.
- Schedule an HVAC inspection before cold fronts arrive.
- If your system is 15+ years old, consider an efficiency upgrade before winter peaks.
3. Overnight Prep Before a Hard Freeze
Extreme cold events in the Shoals often come overnight when temperatures drop fastest. Preparing before you go to bed can mean the difference between a minor chill and a major repair bill.
Quick overnight checklist:
- Set the thermostat to at least 68°F—don’t turn the heat off to “save money.”
- Keep interior doors open for better heat circulation.
- Close garage doors to protect pipes near shared walls.
- Cover or insulate outdoor vents and spigots.
- If traveling, have a neighbor check the property or shut off the main water supply.
4. When to Call for Emergency Service
If your pipes stop flowing, your heater shuts down, or you see water pooling inside, call a professional immediately. Delaying repairs during a freeze can multiply damage.
Call BTI Plumbing & HVAC right away if you notice:
- No water flow or frozen lines
- Water stains on walls or ceilings
- Loud banging (“water hammer”) in pipes
- Furnace blowing cold air or cycling constantly
Our 24-hour emergency service ensures Florence homeowners get help fast when winter hits hardest.
5. Bonus: Simple Winter Energy Savings
While protecting your home from cold damage, you can also cut energy waste.
- Seal drafts around windows and doors.
- Use a programmable thermostat to maintain consistent heat.
- Add attic insulation to keep warmth inside.
These small steps reduce heating costs while easing stress on your system.
