10 Must-Do HVAC Tips As Orillia’s Heat Hits

By Kristina Unruh • July 16, 2025
When summer rolls into Orillia, your air conditioner becomes one of the most important parts of your home. To keep your system running smoothly all season long, the team at Mr. Heat Furnace Orillia has put together this list of 10 simple HVAC tips you should follow before the real heat arrives. 1. Change Your Air Filter A clean air filter helps your system run better and keeps your indoor air fresh. Replace it every 1–2 months during summer. 2. Test the Thermostat Turn your system to “cool” and make sure the AC kicks in. If it doesn't, call for a tune-up before things get hot. 3. Upgrade to a Smart Thermostat A programmable thermostat can save you money by cooling your home only when you need it. 4. Clear the Outdoor Unit Cut back any weeds or plants around your AC. Leave at least 2 feet of space for proper airflow. 5. Rinse the Condenser Coils Use a garden hose to gently rinse off dirt and debris from the outdoor coils. This boosts efficiency and cooling power. 6. Schedule a Professional Tune-Up A summer HVAC check-up in Orillia ensures your system is ready for the season. We’ll check all parts, clean coils, inspect refrigerant levels, and more. 7. Seal Doors and Windows Keep the cool air in and hot air out. Use weather stripping and check for drafts. 8. Open All Vents Blocked vents reduce airflow and make your system work harder. Keep furniture and rugs away from vents and registers. 9. Check the Drain Line Your AC’s drain line can clog with dirt or algae. Flush it with a bit of white vinegar or call us to clean it professionally. 10. Plan Ahead for Repairs If your system is older or hasn’t been serviced in a while, don’t wait for a breakdown. Get a check-up early and avoid emergencies.

Why Your Furnace Blows Cold Air During Orillia’s Deep Freezes

December 16, 2025

Few things are more stressful during an Orillia winter than turning on the furnace… and feeling cold air coming through your vents. It happens more often than you’d think, especially during the sudden temperature drops Orillia is known for.

Here are the most common causes we see:


1. The furnace overheated and shut down

When airflow is restricted—usually due to a dirty filter—the furnace can overheat and trigger a safety shutdown. The fan keeps running but the heat stops.


2. Frozen vent pipes

Orillia’s deep freezes often cause frost buildup in high-efficiency furnace vent pipes. When this happens, the furnace can’t ignite properly and may run without producing heat.


3. Ignition or flame sensor issues

Cold temperatures make ignition components work harder. If your furnace tries to light but the flame sensor doesn’t detect heat, it will shut down for safety.


4. Low gas pressure during extreme cold

During provincial cold snaps, natural gas pressure can drop slightly. Furnaces with borderline performance may fail to ignite consistently.


What to Do

If your furnace is blowing cold air, shut it off, check the filter, and make sure your exterior vent pipes aren’t buried in snow or ice.
If everything looks normal, call Mr. Heat Furnace Orillia—we can usually diagnose the issue within minutes.
