Home comfort audit for condo overheating in Greater Vancouver

Condos in Greater Vancouver are notorious for overheating, even in cooler months, thanks to large windows, heat from neighbouring units, and limited control over building systems. A home comfort audit for an overheating condo focuses on what you can actually influence within a strata unit. Here is how to bring the temperature back into a comfortable range.

Why condos overheat

Modern condos are well sealed and surrounded by other heated units, so they hold heat readily. Large windows, often facing south or west, create significant solar gain that pushes indoor temperatures up during the day. Heat rising through the building and from units below adds to it, and many condos have limited or no cooling.

Building systems also play a role. Some stratas run shared heating that residents cannot fully control, and ventilation may be limited. In a tightly sealed condo, internal heat from appliances and electronics has nowhere to go, so the unit can feel warm even when it is cool outside.

• Large south- or west-facing windows creating solar gain
• Heat from neighbouring units and floors below
• A tightly sealed envelope trapping internal heat
• Limited or no dedicated cooling in the unit
• Shared building heating that residents cannot fully control

What a comfort audit checks and what you can do now

A comfort audit for a condo focuses on what is within your control: window solar gain, ventilation, and cooling options that suit strata rules. It evaluates whether a ductless head or another strata-friendly cooling solution fits your unit and building requirements, since exterior changes usually need strata approval.

You can ease overheating right away. Use blinds or solar shades on sun-facing windows during the day, and ventilate in the cooler evening and morning hours. Set any thermostat you control to a lower target and use the fan to circulate air. If your unit lacks effective cooling, a ductless heat-pump head is a common condo solution, subject to strata approval; HeatLand can advise on options, and qualifying heat-pump installations may be eligible for FortisBC and CleanBC rebates.

• Ventilate during cooler evening and morning hours
• Lower any thermostat you control and circulate air with the fan
• Explore a strata-approved ductless cooling option for the unit

Frequently Asked Questions

Why does my condo overheat even when it is cool outside?

Condos are tightly sealed and surrounded by other heated units, so they trap heat. Large sun-facing windows add solar gain, and internal heat from appliances has nowhere to escape. Many units also lack dedicated cooling, so the warmth builds up.

What can I do about overheating if I can't change the building system?

Focus on what you control: shade sun-facing windows during the day, ventilate in the cooler hours, and circulate air with a fan. If the unit lacks cooling, a strata-approved ductless head is a common solution worth exploring.

Can I add cooling to a condo?

Often yes, commonly with a ductless heat-pump head, but exterior changes usually require strata approval first. HeatLand can advise on options that fit your unit and building requirements, and qualifying installations may be eligible for FortisBC and CleanBC rebates.

Do window coverings really help with condo overheating?

Yes. Blinds or solar shades on south- and west-facing windows block a meaningful share of the solar gain that drives daytime overheating, and they are one of the simplest changes a resident can make without strata approval.
