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.

How to Prepare Your Orillia Home for a Harsh Winter (Expert HVAC Checklist)

December 11, 2025
Orillia winters can be unpredictable—one day mild, the next extremely cold. The best way to avoid emergency furnace calls is to prepare your HVAC system before the season hits its peak. Here’s a homeowner-friendly checklist used by the technicians at Mr. Heat Furnace Orillia : 1. Replace your furnace filter before the temperature drops A fresh filter improves airflow, reduces energy bills, and helps prevent overheating shutdowns. 2. Schedule a fall furnace tune-up Tune-ups catch early signs of ignition issues, blower problems, cracked hoses, and worn components—all of which commonly fail during heavy winter use. 3. Clear snow and ice from exterior vents High-efficiency furnace vent pipes can freeze easily. Keeping them clear ensures your system runs safely. 4. Test your thermostat settings Make sure your thermostat responds properly and is placed away from cold drafts. 5. Seal windows and doors Even the best furnace can’t compensate for major heat loss around windows and doorframes. Weatherstripping and caulking can drastically reduce heating costs. 6. Listen for unusual furnace sounds Banging, rattling, or grinding noises are early indicators of a mechanical failure. Why It Matters Preventative work saves Orillia homeowners hundreds of dollars in avoided breakdowns and keeps your home consistently warm through the coldest storms. If you want peace of mind this winter, Mr. Heat Furnace Orillia can perform a complete winter-readiness check to make sure your system is prepared for whatever the season brings.

The Most Common Furnace Repairs We See in Orillia Every Winter

December 8, 2025
Winter is our busiest season at Mr. Heat Furnace Orillia , and year after year, we see the same types of furnace failures once temperatures drop below freezing. If you’re a homeowner in Orillia, here are the issues most likely to affect you: 1. Faulty Flame Sensors Flame sensors get coated in carbon from heavy winter use, causing the furnace to shut down repeatedly. A quick cleaning usually solves the issue. 2. Blower Motor Problems When the blower motor wears out, homeowners hear grinding, humming, or squealing noises. In winter, motors work harder and failures become common. 3. Pressure Switch Failures This small but crucial part detects airflow inside your furnace. When it fails—or when vent pipes get blocked—the furnace won’t start. 4. Limit Switch Trips If your furnace overheats (often from a clogged filter), the limit switch triggers a safety shutdown. These repeated trips can eventually wear it out. 5. Thermostat Malfunctions Old thermostats often misread temperatures in cold weather, causing short cycling or heat loss. Why Winter Repairs Are More Urgent Cold temperatures make minor issues escalate quickly. A furnace working at 50% capacity in November can fail completely during January’s cold snaps. At Mr. Heat Furnace Orillia , we prioritize fast winter response, same-day repairs, and honest pricing—because no homeowner should be left without heat.

Simple Summer HVAC Tricks to Lower Your Orillia Cooling Bills

July 18, 2025

Summer is beautiful in Orillia, but those rising temperatures can also raise your energy bill. At Mr. Heat Furnace Orillia, we help homeowners stay cool without spending a fortune. These simple HVAC tips can cut your cooling costs and make your system last longer.


1. Use a Programmable or Smart Thermostat

A smart thermostat adjusts your cooling when you're not home, helping you save energy without lifting a finger. Set it a few degrees higher while you’re away to cut costs.


2. Close Blinds and Curtains During the Day

Direct sunlight heats up your home fast. Close your blinds during the hottest part of the day to keep your rooms cooler naturally.


3. Use Ceiling Fans the Right Way

Fans don’t cool the air—they move it. Set ceiling fans to spin counterclockwise in summer to push cool air downward. This makes your home feel cooler without lowering the thermostat.


4. Keep Vents and Filters Clean

Blocked vents or dirty air filters make your system work harder. Make sure furniture isn't covering vents and replace filters every 1–2 months during summer.


5. Shade the Outdoor AC Unit

Your AC will run more efficiently if it’s in a shaded area. Plant a bush nearby or add a small awning—but leave plenty of space around it for airflow.


6. Seal Air Leaks in Your Home

Cool air can escape through small cracks around doors and windows. Use weather stripping or caulking to keep the cool in and the heat out.


7. Schedule a Summer Tune-Up

Regular maintenance helps your system run better and avoid surprise breakdowns. At Mr. Heat Furnace Repair Orillia, we offer affordable AC tune-ups to keep things running smoothly.
