How to Fix a Room That Won’t Heat Up in Your Alberta Home

March 25, 2025

Alberta winters can be brutal, and a room that won’t heat up properly can make your home feel uncomfortable. Whether it's an issue with insulation, airflow, or your heating system, here are the most common causes and practical solutions to get that stubbornly cold room warm and cozy.

1. Check for Insulation Issues

Poor insulation is one of the biggest reasons a room stays cold. Heat can escape through the walls, ceiling, and floors, making it harder for your heating system to maintain a comfortable temperature.


Solution:


  • Inspect windows and doors for drafts. Apply weather stripping or caulking to seal any gaps.


  • Consider adding insulation to exterior walls and the attic.


  • Use thermal curtains to help retain heat inside the room.

2. Evaluate Your HVAC System

Sometimes, the issue isn’t with the room itself but with the heating system’s ability to distribute warm air evenly.


Solution:


  • Check vents and registers to ensure they’re fully open and not blocked by furniture.


  • Have your furnace and ductwork inspected to confirm they’re clean and functioning efficiently.


  • Consider installing a duct booster fan to improve airflow to the colder room.

3. Address Window and Door Heat Loss

Windows and doors can be major sources of heat loss, especially in older homes.


Solution:


  • Upgrade to energy-efficient, double or triple-pane windows.


  • Use draft stoppers at the base of doors to prevent heat from escaping.


  • Apply plastic film insulation to windows in the winter to minimize heat loss.

4. Consider a Ductless Split System or Space Heater

If the room remains cold despite addressing insulation and HVAC issues, supplemental heating may be necessary.


Solution:


  • A ductless mini-split system provides efficient heating for specific rooms.


  • Use an electric space heater as a temporary fix, but ensure it's safe and energy-efficient.


  • A radiant floor heating system can also help maintain consistent warmth.

5. Balance Your Home’s Heating

Uneven heating can be caused by an unbalanced HVAC system, where some rooms receive more heat than others.


Solution:


  • Adjust dampers in your ductwork to direct more warm air to the cold room.


  • Use a smart thermostat to control temperature zones more effectively.


  • Have an HVAC technician perform an airflow balancing assessment.

Final Thoughts

If one room in your home won’t heat up, don’t just bundle up and hope for the best. Identifying the root cause and applying the right solution can make all the difference in ensuring a comfortable and energy-efficient home. With proper insulation, an optimized heating system, and possible supplemental heating, you can enjoy a warm home even during Alberta’s coldest months.

Monthly Maintenance Membership

Are Monthly Maintenance Memberships Worth the Money? Monthly Maintenance Memberships have features and benefits beyond a simple tune-up, when taken advantage of, these memberships can save the homeowner hundreds or even thousands of dollars. Although they are not for everyone, they are for some. Take my friend Adam for example, this guy can fix just about anything and in the rare chance that he finds himself in a pickle, he knows a guy! Sometimes that guy is even yours truly. Most people do not have “a guy” or the multitude of skills that Adam has and even if they do, they rarely have the time to deal with preventative maintenance in their busy lives. Preventive Maintenance put simply, is about fixing things before they break. Our busy lives tend to take president over remembering to maintain the pumps, motors, fans, filters, and pulleys that provide the comfort in our homes, even though these systems run on average 600 times longer and harder than your vehicle does on an annual basis. Yikes…bet you didn’t know that.
