Indoor air temperature plays an important role in how comfortable and healthy your home feels. While most people think about temperature in terms of heating and cooling costs, it also affects indoor air quality, moisture levels, and the potential for mould growth.
If certain rooms feel too warm, too cold, damp, or stuffy, temperature may be part of the issue.
Comfort and Health
When indoor temperatures fall outside recommended ranges, you may notice:
-
Discomfort or uneven temperatures between rooms
-
Condensation on windows or cold surfaces
-
Stale or heavy-feeling air
-
Increased humidity problems
Temperature works together with humidity. Warm air can hold more moisture, and when that moisture settles on cooler surfaces, it may create conditions where mould can grow.
Recommended Indoor Temperature Ranges
Guidelines from ASHRAE suggest the following general comfort ranges:
-
Summer: 23–26°C
-
Winter: 20–26°C
Every home is different, and factors such as insulation, ventilation, and occupancy patterns can influence what feels comfortable and healthy.
How Temperature Is Assessed During an Air Quality Survey
During an indoor air quality (IAQ) survey, air temperature is measured along with:
-
Relative humidity
-
Ventilation conditions
-
Visible signs of moisture or condensation
Looking at these factors together helps identify whether your indoor environment supports comfort and reduces the risk of moisture-related problems.
Indoor Air Quality Support for Homeowners
LCS Laboratory Inc. provides indoor air quality assessments for homeowners who want a clearer understanding of their indoor environment. Temperature and humidity measurements are part of a broader evaluation designed to identify conditions that may affect comfort or air quality.
