Holiday HVAC Tips for a Safe, Comfortable Home

The holidays should be warm, relaxed, and stress-free. The last thing you need is a surprise furnace breakdown when guests are over. Use these holiday HVAC tips from Andersen Heating & Cooling to help your HVAC system run safely and efficiently, keep guests comfortable, and avoid major issues when service calendars are the busiest. You can follow this HVAC safety and maintenance checklist to prepare your home for the holidays in the Charlotte, NC area.

1. Schedule a pre-holiday HVAC tune-up

A professional heating tune-up catches worn parts early, cleans critical components, and verifies safe operation under winter loads. You will get:

• Better airflow and even room temperatures
• Lower energy use from a clean, well‑calibrated system
• Fewer surprises during cold snaps and family gatherings

If you haven’t had heat pump or furnace maintenance this year, schedule a visit now to get ahead of the holiday rush. Ask about our maintenance plans for simple peace of mind year-round in the Charlotte area.

2. Replace filters for cleaner indoor air

A clogged filter restricts airflow, forces longer run times, and spreads dust. Install a fresh filter before guests arrive. This helps:

• Improve indoor air quality for sensitive family members
• Reduce odors and dust stirred up by holiday activity
• Maintain consistent heating without straining the system

Tip: Check high‑MERV or allergen filters monthly during peak use.

3. Keep vents and returns clear

Holiday décor and furniture changes often block grilles without anyone noticing. Walk through each room and confirm:

• Supply vents are not covered by rugs, gifts, or furniture
• Return grilles are not obstructed by wreaths, stockings, or boxes
• Registers are open for balanced airflow throughout the home

Good airflow reduces hot and cold spots and keeps the furnace from short cycling.

4. Set your thermostat to the right temperature for gatherings

Dishes roasting in the oven, holiday lighting, and extra people can all add heat. Before company arrives:

• Lower the set point a few degrees to prevent overheating
• Use a programmable or smart thermostat to pre‑adjust for events
• Avoid large manual swings; gradual setbacks are more efficient

A smart thermostat also lets you monitor and adjust temperatures if you step out. We can walk you through all of your options to help you find the right model for your home.

5. Improve indoor air quality during the holidays

Holiday candles, fireplaces, and cooking can leave indoor air stuffy. Consider:

• Whole‑home air purification or UV treatments for ongoing IAQ
• Bath and kitchen ventilation while cooking or hosting
• A whole‑home humidifier to maintain balanced winter humidity

The EPA advises keeping indoor humidity between 30% and 50% and changing HVAC filters regularly to help maintain healthy indoor air quality. If you have questions about your indoor air quality, reach out to us today.

6. Decorate safely around heating equipment

Keep combustible décor away from heat sources and maintain clearances. Here are a few simple holiday HVAC tips for your safety:

• Do not place garlands, trees, or storage boxes within three feet of vents, radiators, or space heaters
• Keep the furnace closet clear and the outdoor heat pump free of debris
• Avoid covering thermostats with decorations that can give false readings

Safety clearances will preserve efficient airflow and reduce fire risk.

7. Prepare for cold snaps and power surges

Sudden temperature drops are common during North Carolina winters. Plan ahead:

• Seal drafts at doors and windows to reduce heat loss
• Consider surge protection for HVAC equipment and major appliances
• Know where your water shutoff is and open cabinet doors on exterior walls during hard freezes to protect pipes

Sealing air leaks and adding insulation can improve comfort and deliver up to ~10% annual energy-bill savings. These small steps can prevent costly mid‑season repairs.

8. Travel settings and freeze‑prevention checklist

Packing up for a winter vacation? If you will be away from Charlotte for the holidays:

• Set your thermostat no lower than 60°F
• Close and lock windows, then check weatherstripping
• Replace the filter and clear returns so the system can breathe
• Arrange for a neighbor to check the home during extreme cold

A stable set point can protect your home and reduce the chance of emergency service calls.

9. Book Your HVAC service before the rush

Peak winter demand can lengthen response times. If your system is due for maintenance, makes unusual noises, or struggles to hold temperature, schedule a furnace tune-up now. Proactive care is the most cost‑effective way to improve comfort, safety, and efficiency.

Frequently Asked Questions

How soon before the holidays should I schedule furnace maintenance? Two to four weeks ahead is ideal. You will have time for any minor fixes before cold weather and events.

What temperature should I set when hosting? Lower the thermostat by two to three degrees before guests arrive. Body heat and cooking will bring the temperature back up quickly.

Is it okay to close supply vents in unused rooms? No. Closing vents can increase system static pressure, reduce efficiency, and cause comfort issues. Leave vents open and balance airflow with dampers if available.

Should I cover my outdoor heat pump in winter? Do not fully cover a heat pump. It needs airflow to defrost. Keep it clear of leaves and snow and maintain the recommended clearance.
