Humidifiers and humidity control in Calgary
Calgary runs dry for most of the heating season. Dry indoor air builds static and pulls moisture out of hardwood floors and furniture. We install, service and repair whole-home humidifiers, portable units and dehumidifiers.
Why Calgary homes go dry in winter
A furnace heats the air, and heated air carries its moisture differently. Across a long Calgary heating season the relative humidity indoors falls, and the house starts telling you about it. The proper humidity level for an average home is between thirty-five and forty-five percent. Below thirty-five percent, a humidifier is what brings it back up.
- Static shocks and clinging fabrics
- Hardwood floors, furniture joints and cabinetry that shrink and crack
- Air that feels colder than the number on the thermostat
The most neglected appliance in the house
Homeowners keep an eye on the furnace, the air conditioner and the water heater. The humidifier sitting beside them gets forgotten — no cleaning, no filter change, no annual service. Water panels scale up, float valves corrode and solenoid valves seize. A humidifier that has stopped working does not announce it. The air simply goes dry, and most people put it down to the season.
Humidifier or dehumidifier — which do you need?
Humidifiers add moisture to indoor air when humidity falls below thirty-five percent. Dehumidifiers remove moisture when humidity rises above fifty percent. Which one you need depends on the season, how many people live in the home, and what the air is doing right now. The Healthy Home Check measures it rather than guessing.
Whole-home humidifiers
Installed directly on the furnace, a whole-home humidifier adds moisture to the air as it circulates through the ductwork, holding the same level in every room at once. No tanks to refill and no portable units to move around.
- Used through the winter months, when the air is dry
- Flow-through (bypass) and fan-powered models
- Water panel filter replaced once a year
- Runs quietly in the background through the season
Dehumidifiers
When humidity climbs above fifty percent, mould, mildew and dust mites have the conditions they need. Calgary basements and warm, damp summer weather both produce it. A dehumidifier removes the excess moisture before it does damage.
- Reduces moisture in basements and crawlspaces
- Protects stored items, drywall and insulation
- Whole-home units tie into the existing HVAC system
- Portable units where only one room is affected
What balanced humidity does for your home
Static
Dry air lets static build until everything you touch gives you a shock and fabrics cling. Holding the air in range stops the charge from accumulating.
Wood and furniture
Hardwood floors crack, furniture joints loosen and pianos drift out of tune in dry air. Holding thirty-five to forty-five percent through the winter stops wood swinging between swelling and shrinking.
How warm the house feels
Air at a balanced humidity feels warmer than dry air at the same temperature. You can be comfortable without pushing the thermostat higher, which takes some of the load off the furnace.
Balanced air, every room
Optimal humidity levels reduce the static electricity that dry air produces. They also preserve wood floors and furniture, preventing damage and keeping their appearance through the year as temperatures swing.
A whole-home humidifier holds the same humidity in every room, and it stays that way as the outdoor temperature moves around.
Humidifier repairs and installation
Also known as whole-house humidifiers, AC humidifiers work in conjunction with your furnace and air conditioning system to hold proper humidity levels across the home. Portable humidifiers control humidity in a single room. Which you get depends on your needs and your budget — some portable units can monitor the moisture level across a whole home and can be combined with your HVAC system. They require little to no maintenance, are quiet, and cost very little to run.
Whether you need an AC humidifier or a portable unit, we fit humidifiers from established manufacturers. What our work is covered by is set out in the AIC Guarantees. Control the climate in your home more easily with a smart home thermostat.
Dehumidifier installations and repairs are carried out by our own technicians, for whole-house and single-room humidity control. We will also show you how to maintain the unit so it runs without trouble.
Annual maintenance keeps a humidifier working
Water panels, float valves and solenoid valves need service once a year, at the start of the heating season. The water panel collects mineral scale from Calgary’s water and gets replaced. Book it alongside the furnace tune-up and it happens on one visit.

Humidifier questions
What humidity level should a Calgary home sit at?
Between thirty-five and forty-five percent for an average home. Below thirty-five percent, a humidifier is what brings it back up. Above fifty percent, a dehumidifier is the right tool — most often in a basement or through a warm, damp stretch of summer.
How often does a whole-home humidifier need servicing?
Once a year, at the start of the heating season. The water panel collects mineral scale from Calgary’s water and is replaced. The solenoid valve and the float assembly are checked at the same time — those are the parts that fail quietly, with no sign except air that has gone dry.
Can a whole-home humidifier go on any furnace?
In most cases, yes. Bypass models work with single and two-stage furnaces, and need a water supply connection plus a connection to the supply and return ducts. Fan-powered models have slightly different requirements. We confirm compatibility with your system before installation.
My humidifier runs but the air still seems dry. Why?
Most often a solenoid valve that no longer opens to let water through, a water panel clogged with scale, or a humidistat set wrong. It can also be undersized for the volume of air in the house. We diagnose on site and give you a written price for repair or replacement before anything is done.
Will a whole-home humidifier raise my energy bill?
The unit itself uses very little. Balanced humidity also makes the same temperature feel warmer, so the heating does not have to work as hard to keep the house comfortable.
Does a humidifier reduce static electricity?
Yes. Static builds up in dry air. Adding moisture stops the charge accumulating, which is why the shocks and the clinging fabrics stop once the air is back in range.
Is a whole-home unit better than a portable one?
A whole-home unit holds the same humidity everywhere and does not need refilling. A portable unit covers one room and has to be topped up and cleaned. If only one room is a problem, a portable unit is the cheaper answer.
Is the installation disruptive?
The unit goes on the furnace, with a water line run to it and a wire to the humidistat. It is usually a half day or less. We confirm a two-hour arrival window with you before the visit.
Can a humidifier cause mould?
It can, if it is set too high or left uncalibrated — that is what excess moisture does. Held in the thirty-five to forty-five percent range it does not. Setting that range is part of the installation and it is checked again at the annual service.
What customers say
Great customer service. We were treated like friends. Very helpful team.
Pedro Jose
Fantastic company. From the thorough consultation to the installation, everyone we dealt with was professional, knowledgeable, efficient and responsive. They cleaned up after themselves and explained everything we needed to know. I would highly recommend this company for any AC, heating or water tank needs.
Lesley Sugden
Was very well versed with the service that was going to be provided. I am quite happy it was him that came to explain things — sometimes you don’t have the questions to ask, but with the knowledge he had, I was put at peace. I would recommend Daryl to everyone. Daryl and James came on a follow-up and were exceptional. Thanks for the service.
