Preventing Frozen Pipes and HVAC Line Freeze-Ups During Winter Storms
Protect Your Home Before Freezing Temperatures and Sleet Arrive in North Texas
As winter approaches and forecasters predict sleet and freezing temperatures in the McKinney and North Texas region, homeowners face a threat that goes beyond just staying warm: frozen pipes and HVAC system failures. At Crow’s Heat & Air, we’ve served the Collin County community for over 30 years, and we’ve seen firsthand how quickly a winter storm can turn a comfortable home into a freezing nightmare when pipes freeze and heating systems fail. The good news is that frozen pipes and HVAC condensate line freeze-ups are largely preventable. With proper preparation and knowledge, you can protect your home, maintain your comfort, and avoid emergency repair bills that can easily exceed $5,000. This guide walks you through practical steps to safeguard both your plumbing and heating system before dangerous winter weather strikes.
Understanding the Frozen Pipe Crisis
Water expands when it freezes, creating tremendous pressure inside your pipes. When pipes freeze and burst, water damage can devastate your home quickly and expensively. But pipes aren’t the only victims of winter freeze-ups. Your HVAC system produces condensation that must drain away through condensate lines. When these lines freeze, your furnace automatically shuts down as a safety measure, leaving your home without heat during the coldest nights. The pipes most vulnerable to freezing include those in unheated spaces like attics, basements, and garages, as well as pipes running along exterior walls with little insulation. HVAC condensate lines are equally vulnerable, especially if they’re routed outdoors or through unheated spaces.
Insulate Vulnerable Pipes and HVAC Lines Now
The most effective prevention starts with proper insulation. Before temperatures drop, wrap exposed pipes in foam insulation sleeves or fiberglass insulation. Pay special attention to pipes in unheated areas: under sinks near exterior walls, in crawl spaces, basements, garages, and attics. For your HVAC system, ensure your condensate lines are properly insulated. If lines run outdoors, this becomes even more critical. Consider installing heat tape around vulnerable condensate drain lines. Heat tape activates automatically when temperatures drop, providing just enough warmth to keep water flowing and prevent ice blockages. This is one of the most cost-effective investments you can make to prevent winter HVAC failures.
Maintain Consistent Heat and Airflow
Never completely shut off your heating system during freezing weather, even if you’re leaving town. This is one of the most common mistakes homeowners make. Maintaining consistent indoor temperatures keeps pipes warm. During extreme cold snaps, leave your thermostat at the same setting day and night, even if it slightly increases your heating bill. The cost is negligible compared to frozen pipe repairs. Additionally, open cabinet doors under sinks to allow warm air circulation around plumbing. Close garage doors and seal any gaps, cracks, or openings where cold air might infiltrate and chill your pipes.
Professional Inspection Before the Deep Freeze
The best time to prevent problems is before winter arrives. Schedule a professional HVAC inspection with Crow’s Heat & Air before freezing temperatures hit. Our licensed technicians can identify vulnerable condensate lines, check pipe insulation, verify proper drainage slope on condensate lines, and ensure your furnace is operating efficiently. We’ll clean condensate lines to remove debris, algae, or mineral deposits that could clog lines and cause backups. Regular maintenance is your first line of defense against winter emergencies.
Prepare for Extreme Cold with Emergency Knowledge
If a freeze does occur, know the warning signs: little or no water pressure, visible frost on pipes, bulging pipes, or gurgling sounds. If you suspect frozen pipes, turn off the main water supply first, then apply gentle heat using a hair dryer or heat lamp. For your HVAC system, check your condensate drain for ice buildup. If you see an issue, call a professional immediately rather than trying to DIY a fix that could cause further damage.
