Humidifier + heating: the unexpected duo for maximum comfort in winter

Well-balanced humidity: the forgotten key to winter comfort in Montréal, Laval and surrounding areas

When temperatures drop in the winter across Montréal, Laval, Longueuil, the North Shore and South Shore, households and businesses naturally focus on heating. But at AirGreen, we know that true thermal comfort doesn’t depend on warmth alone. It also hinges on a factor that’s often overlooked: the humidity level in the air. That’s where an underrated yet incredibly effective duo comes in — the humidifier paired with a central heating HVAC system.

In this article, we’ll dive into the synergy between humidification and heating, explain why it’s essential for full comfort, and share real-world AirGreen installation stories that demonstrate the direct benefits of this combo — whether in single-family homes or commercial buildings.

Why Québec winters dry out your comfort

The harsh winters in our region don’t just bring cold air. The combination of frigid outdoor temperatures and continuous indoor heating creates an extremely dry environment, with relative humidity often dropping below 25%. This leads to:

  • Dry skin and chapped lips

  • Respiratory discomfort (especially for children and seniors)

  • Sinus irritation

  • Damage to hardwood floors, furniture, and door frames

  • Persistent static in clothes and hair

That’s why even the best heating system alone won’t cut it. You also need to balance your indoor humidity to achieve truly comfortable living conditions.

The role of an integrated humidifier in an HVAC system

At AirGreen, we regularly install central humidifiers directly connected to forced-air heating systems. These humidifiers distribute controlled humidity evenly throughout the home or building using the existing ventilation ductwork.

The most popular models we recommend include:

  • GeneralAire 1042LH – Evaporative, efficient for homes up to 3,000 sq. ft.

  • Honeywell HE300 – Steam-based, ideal for precise control in large spaces

  • Aprilaire 700M – High-output, quiet, suited for residential environments with sensitivity needs

These systems are automated and smart, capable of monitoring humidity levels and adjusting their operation in real-time based on your home’s requirements.

Case study: Laval — A single-family home regains balance

Last January in Laval, a family reached out to us about persistent indoor dryness. Their two-story home, heated by a Goodman 60,000 BTU forced-air system, had a consistent humidity level of just 22%, despite keeping the thermostat at 21°C (70°F).

Our team installed a GeneralAire 1042LH central humidifier, directly integrated into the existing furnace. In less than 48 hours, humidity rose to 38%, eliminating issues like dry throats, creaking floors, and excessive static. The family reported increased comfort without changing the temperature — all for a very reasonable investment that quickly paid off.

Heating + humidification: the combined benefits

Here’s why this duo is becoming increasingly popular with our customers throughout the Greater Montréal Area:

Enhanced comfort at a lower temperature

A well-balanced humidity level helps you feel warmer at the same temperature. This means you can lower your thermostat slightly (e.g. from 22°C to 20°C) without sacrificing comfort. The result: guaranteed energy savings.

Protection for your home’s materials

Balanced humidity protects floors, wooden furniture, doors, and windows from drying, cracking or warping.

Optimized respiratory health

Overly dry air promotes the spread of viruses and worsens asthma or allergy symptoms. By maintaining a humidity level between 35% and 45%, you simply breathe better.

Invisible solution, no daily maintenance

Once installed by our certified team, your central humidifier works in the background, with no daily input needed. Just one annual maintenance check keeps it running optimally.

What you need to know before installing a humidifier with your heating system

Choose the right model for your space

We always perform a precise calculation of the required humidity load, based on your interior air volume, insulation levels, and current heating system.

Check compatibility with your furnace

Most forced-air systems are compatible with humidifiers, but some older models may require specific modifications or accessories. Our technicians handle everything.

Plan for annual maintenance

Like any HVAC component, we recommend annual maintenance to prevent lime scale buildup or bacterial growth. At AirGreen, we offer a yearly maintenance plan to ensure your unit performs consistently.
