How to Prepare Your HVAC for Winter Weather
Winter can sneak up on you. One day you’re enjoying crisp air and blue skies, then suddenly—bam!—temperatures plunge, pipes groan, and your furnace groans louder. At Kingstar HVAC, we know how a cold snap can turn a small oversight into a big emergency.
We’ve helped countless homeowners avoid frozen coils, burst pipes, and furnace failures. Let’s walk through what you can do right now to keep your home safe, warm, and headache-free all season.
Why Winter Prep Matters ❄️
Your HVAC system is like the heart of your home. When winter hits, it works overtime. If it’s not ready, you risk more than just chilly toes:
- Frozen Coils: Low temps can freeze the refrigerant in your system, leading to cracks or leaks.
- Burst Pipes: Uninsulated pipes expand and burst, causing water damage and expensive repairs.
- Fire Hazards: Dirty filters and blocked vents force your furnace to work harder, which can overheat components.
- Emergency Breakdowns: The last thing you want is a furnace failure on a frigid night, scrambling for emergency hvac help.
A little prevention goes a long way. A tuned-up system also runs more efficiently, saving you money and extending its lifespan.
DIY Winterization Steps
Not every task requires a toolbox full of gadgets. Many steps are simple, safe, and can be done in an afternoon.
1. Change Your Air Filters
Think of your filter as your HVAC’s lungs. A clogged filter suffocates the system. For most homes, change it every 1–3 months in winter, or more if you have pets or allergies.
- Remove the old filter (note size)
- Insert new filter, arrow pointing toward the blower
2. Insulate Exposed Pipes
Look for any copper or PVC pipes near exterior walls. Use foam pipe sleeves or wrap towels and secure with zip ties. This helps prevent freezing and bursting.
3. Clear Outdoor Units
Remove leaves, snow, or debris from around your outdoor condenser. Keep at least two feet of clearance. If you use a heat pump, never cover the unit completely—this can trap moisture and cause rust.
4. Check Your Thermostat
Test your thermostat before the first cold night. Set it to “heat,” and make sure it clicks on. If you have a programmable or smart thermostat, set a schedule to save energy.
5. Inspect Vents & Registers
Walk through your home and make sure all vents and registers are open and unblocked. Furniture or drapes can block airflow, making your system work harder.

Prevention & Maintenance
The best way to avoid winter emergencies is regular care:
- Change filters regularly—even in winter, dust builds up fast.
- Schedule annual professional maintenance.
- Upgrade old thermostats for better efficiency and comfort.
- Consider duct cleaning every few years, especially if you notice more dust or allergy issues.
- Ask about air scrubbers, dehumidifiers, or humidifiers to improve indoor air quality through the dry winter.
Routine attention can extend your system’s life by years and help you avoid costly “surprise” repairs.
Costs & Time Factors
Winter prep doesn’t have to blow your budget. Here’s what to expect:
- Filter: $10–$40 per filter (DIY)
- Pipe insulation: $1–$5 per foot (DIY)
- Professional tune-up: Typically 1–2 hours, depending on system age/complexity
- Emergency repairs: More expensive, especially after-hours, but sometimes unavoidable
Investing a little now can help avoid much bigger bills later. The U.S. Department of Energy recommends annual HVAC maintenance to keep costs down and efficiency up.
When It’s an Emergency
Sometimes, things go wrong fast:
- Furnace won’t start, and it’s below freezing
- Strange burning smells or smoke
- Loud bangs, screeches, or persistent clicking
- Carbon monoxide detector alarm goes off
These are all red flags. Shut off your system if safe, open windows for ventilation, and call for emergency hvac help immediately.
FAQ: Winter HVAC Prep
How often should I have my HVAC serviced?
At least once a year, preferably before winter. More often if you have pets, allergies, or an older system.
Can I cover my outdoor unit in winter?
Generally, no. Heat pumps need to “breathe.” If you want to protect from debris, use a top cover only—never wrap the whole unit.
What temperature should I set my thermostat in winter?
Most experts recommend 68°F when home, and 60–65°F at night or when away. Adjust to comfort, but don’t go too low—pipes can freeze.
How do I know if my pipes are at risk of freezing?
Pipes near exterior walls, attics, or crawl spaces are most at risk. Insulate these, and keep your home at least 55°F, even when away.
Local/Seasonal Considerations 🌨️
Whether you’re in the snowy north or a milder climate, timing matters. Schedule your maintenance before the first freeze. If you’ve had a wet autumn, check for mold or debris around outdoor units. And if you live in an area prone to ice storms, make sure your generator is ready and your thermostat batteries are fresh.
Safety Reminder: Always follow manufacturer instructions and local building codes. When in doubt, don’t guess—call a licensed professional.
