A Proud Canadian HVAC Company
If you’re renting a condo, apartment, or townhouse in Toronto, your HVAC system is likely shared or controlled by the building. Unlike owning a home, renters often have limited control over heating, cooling, and ventilation, but that doesn’t mean you’re powerless. Understanding how your system works, what maintenance you’re responsible for, and how to spot potential problems can save you discomfort and unexpected costs.
Shared HVAC systems are usually maintained by the building, but renters should know how to identify issues.
Regular checks and reporting small problems early prevents bigger issues.
Proper thermostat use, airflow awareness, and seasonal adjustments improve comfort and efficiency.
Air filters and personal maintenance can improve indoor air quality.
Knowing your rights and responsibilities ensures you don’t get stuck with unnecessary costs.
Renting in Toronto comes with many benefits — flexibility, location, and often less responsibility for major repairs. But one area where renters often feel powerless is HVAC systems. Whether you live in a high-rise condo, mid-rise apartment, or a townhouse complex, heating, ventilation, and air conditioning are often shared or centrally managed.
Even if you don’t own the system, your comfort depends on understanding how it works, when to report problems, and what small steps you can take to improve efficiency. Ignoring issues like uneven heating, poor airflow, or dirty vents can make winters colder, summers hotter, and lead to higher utility bills — all things renters can avoid with a little knowledge.
In many Toronto rental buildings, heating, cooling, and ventilation are shared or centralized, meaning your unit doesn’t have an independent system. Centralized systems can include:
Boilers or furnaces that provide heat to multiple units via radiators or hot water.
Fan coil units or centralized air handlers distributing heated or cooled air.
Split-system AC units or heat pumps that may serve multiple floors or apartments.
For renters, this means your comfort and energy efficiency are tied not just to your apartment but to the whole building. Problems in shared systems — like a malfunctioning boiler, a clogged chiller coil, or unbalanced airflow — can affect multiple units, making it harder to diagnose issues.
Why it matters: Understanding the type of HVAC system in your building helps you set realistic expectations about temperature control, airflow, and maintenance. Some systems allow thermostat adjustments in individual units, while others may only have limited controls. Knowing the system type also helps you communicate clearly with building management when issues arise.
Pro Tip: When you move in, ask the landlord or property manager for a building HVAC overview, including maintenance schedules, system age, recent repairs, and whether any parts are leased or under warranty. This knowledge helps you avoid surprises during extreme weather and ensures your unit is comfortable all year.
While building management is responsible for major repairs and upkeep, renters still play a critical role in maintaining HVAC efficiency and comfort. Ignoring small responsibilities can lead to bigger problems, higher energy costs, or unnecessary strain on shared systems.
Practical steps renters can take:
Air filter replacement: Many apartments allow renters to replace or clean personal filters. Dirty filters restrict airflow, reduce efficiency, and may spread dust or allergens throughout your unit.
Keep vents unobstructed: Avoid blocking vents with furniture, curtains, or rugs. Blocked vents make your system work harder to heat or cool your space.
Thermostat management: Use thermostats wisely. Drastic changes can overwork the system. Set reasonable ranges and avoid frequent on/off cycles.
Prompt reporting: Don’t wait for small issues to become emergencies. Strange noises, temperature inconsistencies, or odors should be reported immediately.
Example: A renter in a downtown Toronto condo noticed a low rumble from the furnace in early November. Reporting it promptly allowed maintenance to fix a partially blocked duct, restoring airflow and preventing a furnace breakdown during the coldest month of the year.
CTA: For guidance on what’s safe for you to maintain versus what should be left to professionals, contact Econoair Heating & Cooling. Our experts help renters understand their responsibilities and keep shared HVAC systems running efficiently.
Even without ownership, renters can take meaningful steps to maximize comfort and minimize energy bills. Small adjustments make a big difference in efficiency and help reduce unnecessary strain on shared HVAC equipment.
Efficiency tips for renters:
Close unused vents: Direct airflow to occupied spaces, improving comfort and reducing wasted energy.
Draft proofing: Use draft blockers, door sweeps, or weather stripping near windows and doors to prevent heat loss in winter.
Use fans strategically: Ceiling or portable fans can help circulate air in the summer, easing the load on shared AC units.
Avoid extreme thermostat changes: Large swings can overwork the system, particularly in older or shared HVAC setups.
Clean vents and registers: Dust and debris reduce airflow and efficiency. Even light cleaning can improve comfort and air quality.
Example: A renter in a mid-rise Toronto apartment kept all vents open, which made certain rooms overly hot while others stayed cold. After consulting with Econoair, they redirected airflow strategically and added a ceiling fan, improving comfort and lowering their energy bill by 15% over the winter.
CTA: Econoair can provide personalized efficiency tips for renters, including airflow assessment and guidance for shared systems. This ensures your unit stays comfortable year-round without overworking the building’s HVAC.
Proactive monitoring is critical for renters. Since shared HVAC systems affect multiple units, early detection prevents minor issues from becoming serious problems that impact comfort and safety.
Signs of HVAC issues to watch for:
Uneven temperatures: Rooms that are unusually hot or cold could indicate blocked ducts or imbalances in the system.
Unusual noises: Rattling, banging, whistling, or hissing are often signs of mechanical issues or airflow problems.
Persistent odors: Musty or burning smells can indicate mold, mildew, or electrical issues.
Humidity problems: Excess moisture or dry air may indicate a malfunctioning humidifier, dehumidifier, or AC system.
High energy bills: Unexpected increases without changes in usage may signal inefficiency or system strain.
Pro Tip: Keep a log of observations — noting when you notice noises, odors, or temperature swings — and report them promptly to building management. This helps maintenance teams address the root cause and protects you from prolonged discomfort.
CTA: Unsure whether what you’re noticing is normal? Contact Econoair for a professional assessment. Our licensed technicians help renters identify hidden issues and recommend solutions that improve comfort and efficiency.
Toronto renters have rights under the Residential Tenancies Act, including the right to a properly functioning heating system. Being informed helps you avoid disputes and ensures your comfort:
Your rights and responsibilities:
Landlord obligations: The landlord must maintain heating systems and ensure units are safe and functional.
Tenant responsibilities: Minor maintenance, like changing filters (if permitted) or reporting problems promptly, is your responsibility.
Health and safety: Repairs affecting health, safety, or habitability must be addressed immediately.
Planning ahead:
Request a maintenance history when moving in.
Conduct seasonal checks to ensure the system works properly before extreme weather.
Keep a record of maintenance requests and responses — this protects you in case of disputes.
Example: A renter in a Toronto high-rise experienced uneven heat. By documenting issues and referencing the Residential Tenancies Act, they ensured prompt landlord action and avoided prolonged discomfort.
CTA: Econoair can advise renters on inspections, preventative care, and efficiency improvements — even in shared systems. We provide the knowledge and tools to help you stay comfortable, safe, and in control, even when you don’t own the building.
In most Toronto condos, apartments, and townhouses, the landlord or building management is responsible for major HVAC maintenance, including boilers, furnaces, AC units, and central ventilation systems. Renters typically handle minor responsibilities such as changing air filters (if allowed), keeping vents unobstructed, and reporting any issues promptly.
It’s important to know your responsibilities versus the landlord’s so you don’t inadvertently take on costly repairs or leave small problems unreported, which can escalate into bigger issues.
CTA: If you’re unsure about what you should maintain versus what the landlord handles, contact Econoair Heating & Cooling. We guide renters on safe, effective HVAC practices and can assess your unit for potential issues.
Even if you don’t own the system, there are clear signs that your HVAC is functioning efficiently:
Consistent temperatures throughout your unit
No unusual noises like banging, rattling, or hissing
Clean air vents with minimal dust or debris
No persistent odors, moisture, or mold in the air
If you notice irregularities such as uneven heating/cooling, strange sounds, or high energy bills, it could indicate a problem in your unit or the building’s shared system.
CTA: Econoair technicians can assess your unit and help you determine if the issues stem from your apartment or the larger building system, giving you clarity and peace of mind.
Absolutely! Even without owning the system, renters can take steps to improve comfort and efficiency:
Keep vents clear of furniture or curtains
Replace or clean personal air filters if allowed
Use fans to circulate air during summer or winter
Close vents in unused rooms to direct airflow
Draft-proof doors and windows to minimize heat loss
These small actions reduce energy consumption, lower bills, and prevent unnecessary strain on shared systems.
CTA: For personalized efficiency tips, contact Econoair. Our team can advise renters on optimizing airflow, maintaining comfort, and extending the life of shared HVAC systems.
Strange sounds like rattling, banging, or whistling, or odors such as burning, mildew, or mustiness, may indicate underlying HVAC issues. Even in shared systems, addressing them early prevents further damage or costly repairs.
Recommended actions:
Document when the noise or odor occurs
Report it promptly to building management
Avoid attempting major repairs yourself if you don’t own the system
CTA: If you’re unsure whether a problem is serious, Econoair Heating & Cooling can perform a professional assessment, helping you understand the cause and advising on next steps.
Sometimes, shared HVAC systems may not provide perfect temperature control in every unit. To stay comfortable:

CTA: If you need guidance on your rights or how to address HVAC problems with building management, Econoair can advise you and provide professional inspections to support your case.
Yes. Even in shared systems, a licensed professional can:
Inspect airflow and vents in your unit

Hi neighbors! Renting a condo, apartment, or townhouse in Toronto is exciting, but shared HVAC systems can bring hidden challenges that affect your comfort and energy bills. Your unit’s heating and cooling doesn’t just depend on a single furnace or AC — shared boilers, heat pumps, ductwork, vents, thermostats, and even building-wide systems all play a role. Blocked vents, uneven airflow, aging equipment, or neglected maintenance in the building can make your unit less comfortable, lead to higher energy costs, and create unexpected frustrations.
At Econoair Heating & Cooling, we help renters across Toronto and the GTA understand and manage their HVAC systems. Our licensed technicians can inspect vents, ductwork, thermostats, and shared equipment to identify potential issues, improve efficiency, and advise on steps you can take to stay comfortable.
Even if you don’t own the building, preventive care and professional guidance matter. By identifying problems early, we help ensure your shared HVAC system operates efficiently, keeps your unit comfortable year-round, and prevents small issues from becoming major headaches — whether it’s staying warm in the winter or cool in the summer.
