Stay Warm This Winter

Canadian winters can be cold. Really, really cold. That’s why Cross Heating & Air Conditioning recommends service and maintenance for your furnace. We want to make sure you and your family stay warm throughout the chilly winter months.

The best time to schedule your service or maintenance with Cross Heating & Air Conditioning is before your home goes cold. Make sure your furnace is performing its best before the snow falls, and enjoy reliable warmth inside your home.

Protect Your Home

Cross Heating & Air Conditioning technicians are experts at servicing and maintaining your natural gas or propane furnaces or boilers. Regular maintenance performed by a certified technician can help ensure your home stays warm all winter long, protecting you and your family—and your furnace warranty.

A broken furnace could leave you with a chill, but it could also leave you with additional home service issues like frozen, broken water pipes. Our trained technicians can help save you time and money by diagnosing and repairing problems before they turn into an emergency.

Comprehensive Inspection Benefits

Cross Heating & Air Conditioning will fully inspect your natural gas or propane furnace or mechanical boiler system to ensure it is running at its best. We may recommend service or repairs that will prevent your furnace from failing during the coldest months of the year. By having your furnace serviced and maintained, you can stay cozy knowing that:

  • You could avoid expensive breakdowns
  • Your furnace is running efficiently, reducing energy costs
  • You’re prolonging the life of your heater

Read through our comprehensive inspection points, which will be performed by a certified HVAC technician.


We want to see how old your furnace is. Even if it is aging, it may not need to be replaced right away. However, if your repair costs are more than half of the price of a new furnace, we may recommend a replacement to save you money in the future.

Reliability checks include:

  • Gas piping leaks
  • Inconsistent or rising temperatures
  • Vent cleanliness and quality

Our HVAC technicians may recommend additional service to ensure your furnace keeps up with the demands of our cold Ontario winters.


Cross Heating & Air Conditioning technicians will check for any strange noises or air impurities. We will ask how your furnace has been performing and if there have been any inconsistent temperatures or frequent breakdowns.

Efficiency checks include:

  • Static and kinetic gas pressure
  • Vent pressure
  • Proper drainage and condensate leaks
  • Safety and high limit flame sense

Our certified technicians will make sure your furnace is running efficiently so it doesn’t affect your utility bills. If any issues are uncovered, our HVAC team may recommend service or repairs that could save you money in the long run.
