HVAC winter prep in Bothell
Fall in Bothell, Washington means crisp mornings, damp afternoons, and the first whispers of winter rain. While the Pacific Northwest rarely experiences extreme freezes, our cool, wet winters place unique demands on home heating systems.
If your HVAC system isn’t ready, you could face:
- ❌ Unexpected furnace or heat pump breakdowns
- 💸 Higher-than-necessary energy bills
- 🌬 Poor indoor air quality from sealed-up homes
- 😬 Comfort issues when the cold snaps arrive
The good news? A little strategic HVAC preparation this fall can ensure your home stays warm, efficient, and healthy all winter long.
At AirLoop Heating & Cooling, we’ve helped Bothell and Snohomish County families for over a decade. Here’s your complete 2025 guide to preparing your HVAC system for winter—from basic homeowner steps to professional tune-ups and rebate opportunities.
🧰 1. Schedule a Fall Furnace or Heat Pump Tune-Up
The single most important step you can take is to schedule professional maintenance before winter hits.
A tune-up typically includes:
- ✅ Inspecting the heat exchanger, burners, and ignition systems
- ✅ Testing refrigerant levels & reversing valve on heat pumps
- ✅ Cleaning coils and blower components
- ✅ Lubricating moving parts for efficiency
- ✅ Verifying safety controls and electrical connections
- ✅ Checking temperature rise and static pressure
👉 Why it matters:
Regular maintenance improves efficiency, reduces breakdowns, and keeps warranties valid.
💡 Pro Tip: Book your tune-up in September or October before the first cold spell. HVAC companies book up quickly once temps drop.
🏠 2. Replace or Upgrade Your Air Filter
Dirty filters restrict airflow, make your system work harder, and worsen indoor air quality.
- Replace 1” filters every 1–3 months.
- Upgrade to MERV 11–13 if you have allergies, pets, or want cleaner winter air.
- Mark replacement dates on your calendar or subscribe to auto-delivery.
In Bothell’s damp fall and winter, filters clog faster than in dry climates — making this a cheap but powerful efficiency boost.
🌬 3. Inspect Ductwork for Leaks or Mold
Hidden leaks in your ducts can waste up to 30% of heated air. Bothell homes, especially older ones, often have ducts in crawl spaces or attics where dampness encourages mold.
DIY checks:
- Feel for air leaks at joints.
- Look for visible gaps or sagging.
- Check registers for low airflow.
Professional duct sealing ensures heated air gets where it’s supposed to — and reduces energy waste significantly.
📟 4. Test and Program Your Thermostat
Before the heating season kicks in:
- Switch your thermostat to “Heat” mode.
- Set it a few degrees higher than the current temperature.
- Listen for the system to respond quickly.
Upgrade to a smart thermostat for:
- Automated schedules that reduce waste
- Remote control via phone
- Learning your habits for max comfort & savings
Bothell families who install smart thermostats often save 8–15% on heating costs each year.
🧼 5. Clean & Clear Around Your Indoor & Outdoor Units
For furnaces:
- Keep 3 feet clear around the unit.
- Remove stored boxes, paint cans, or clutter.
- Vacuum dust buildup around the base.
For heat pumps & outdoor units:
- Clear away leaves, pine needles, and debris.
- Maintain 2–3 feet clearance on all sides.
- Inspect for bent fins or damage.
This simple step helps airflow and prevents system strain during cold, wet weather.
🧯 6. Check Safety Systems & Carbon Monoxide Detectors
If you use a gas furnace, safety is paramount:
- Install or test carbon monoxide (CO) detectors on each floor.
- Replace batteries annually.
- A yellow pilot light can indicate incomplete combustion — call for service if you see it.
CO leaks are rare but dangerous. A quick test could save lives.
🧍 7. Improve Home Insulation & Air Sealing
Your HVAC system is only as efficient as the home it heats. Leaky windows, unsealed attics, and gaps around doors can undo all your HVAC efficiency gains.
Top priorities:
- Add weather stripping to doors and windows.
- Seal gaps with caulk or foam.
- Check attic insulation — aim for 10–12 inches minimum.
- Install door sweeps to block drafts.
Washington’s cool, damp air loves to find its way in — sealing your home keeps warmth where it belongs.

Even with great prep, things can break. A simple emergency plan can keep a minor issue from turning into a disaster.

🔄 10. Know When to Repair vs. Replace
| System Age | Condition | Recommended Action |

| 15+ yrs | Frequent problems, high bills | Replacement |
- Furnace lifespan: 15–20 years

If your unit is aging, replacing it before winter can avoid mid-season breakdowns and let you claim 2025 rebates.
🌿 11. Don’t Overlook Indoor Air Quality
In winter, Bothell homes are sealed up tight. That means dust, mold, and allergens recirculate constantly.
Consider:
- High-efficiency filters (MERV 11–13)
- Duct cleaning every 2–3 years
- UV lights or whole-home air purifiers for added protection
- Humidifiers to combat dry winter air
Clean air isn’t just about comfort — it’s about health, especially for kids, seniors, and allergy sufferers.
