A lot of Markham’s newer growth — Cornell, Berczy Village, and similar communities — is townhouse and stacked-townhouse construction, and the compact mechanical setups in these homes need slightly different attention than a detached house with a full basement.
1. Know Where Your Mechanical Room Actually Is
Townhouse furnace, HRV/ERV, and water heater equipment is often crammed into a small closet or utility room rather than a full basement mechanical area. Know exactly where yours is and make sure nothing is stored in front of it — restricted access delays both routine maintenance and emergency repairs.
2. Replace Filters on Both the Furnace and the HRV/ERV
Compact mechanical rooms mean both filters are often within reach of each other, but it’s still common for homeowners to remember one and forget the other. Check both monthly during the heating season.
3. Book a Fall Tune-Up That Covers the Whole System
A pre-season inspection should cover the furnace, AC, and ventilation system together in a compact townhouse setup — not just the furnace in isolation, since they’re often installed close together and can affect each other’s performance.
4. Watch for Shared-Wall Noise That Isn’t Actually Your System
In attached townhouses, it’s sometimes hard to tell whether unusual noise is coming from your own furnace or a neighbouring unit’s system through a shared wall. If you’re unsure, a technician can confirm which system is actually the source before you book an unnecessary repair.
5. Keep Vents Clear in Smaller Floor Plans
Furniture placement matters more in a townhouse’s typically smaller rooms — a single blocked vent has a proportionally bigger impact on airflow than in a larger detached home.
6. Sign Up for a Maintenance Plan
A maintenance plan that explicitly covers the compact furnace-plus-ventilation setup common in Markham townhouses is worth more here than a generic single-furnace plan, since it’s checking a more tightly integrated system.
The Bottom Line
Most breakdowns in Markham’s newer townhouse communities are preventable with routine attention to both the furnace and the ventilation system together. If you want us to handle that on a schedule, take a look at our maintenance plans — or call us any time your system needs attention now.
