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.

Why Orillia Homes Lose Heat Fast in Winter (And How to Fix It)

December 3, 2025
Orillia winters hit hard—and when temperatures drop suddenly, many homeowners notice the same problem: their homes just don’t seem to hold heat. Rooms feel drafty, the furnace runs constantly, and heating bills spike. At Mr. Heat Furnace Orillia , we see these HVAC Orillia issues every year, and most of them have simple explanations that can be fixed before the coldest months arrive. 1. Furnace filters clogged with winter dust By December, most furnaces in Orillia have been running hard for weeks. Filters clog fast, making the system work overtime and reducing heat output. Changing your filter every 1–2 months can make a massive difference. 2. Leaky ductwork letting warm air escape Homes in Orillia—especially older properties—are known for worn or poorly sealed ductwork. Warm air leaks into basements or walls instead of your living space. A quick duct inspection can recover a surprising amount of lost heat. 3. Thermostat problems in temperature-sensitive areas Installing a thermostat near a cold draft, window, or door can cause your furnace to cycle incorrectly. Homeowners often think the furnace is the issue when it’s actually the thermostat placement. 4. The furnace itself is aging A furnace nearing the end of its lifespan will struggle to keep up during extreme cold snaps. If your system is 15–20 years old, inconsistent heat is a big warning sign. How Mr. Heat Orillia Helps We diagnose heat loss issues from every angle—furnace, ducts, airflow, thermostat placement, and home efficiency. A quick winter tune-up or furnace repair Orillia can stabilize temperatures, reduce energy use, and give you peace of mind all season long. Contact us for fast service!

How to Choose the Right Furnace for Your Orillia Home

November 21, 2025
If your Orillia furnace is nearing the end of its lifespan, choosing a new one can feel overwhelming. The right furnace keeps your home warm, runs efficiently, and suits your budget and climate. Here is what homeowners in Orillia and Simcoe County should consider before buying. 1. Fuel Type Natural Gas: The most common and cost-effective option in Orillia. Propane: Ideal for rural properties without natural gas lines. Electric: Clean and simple, though typically more expensive to run. 2. Efficiency Rating Furnace efficiency is measured by AFUE (Annual Fuel Utilization Efficiency). Standard models: 80–90% AFUE High-efficiency models: 95–98% AFUE A higher AFUE means more heat from every fuel dollar, making it ideal for long Ontario winters. 3. Proper Sizing Bigger is not better. An oversized furnace will cycle on and off too often, reducing efficiency and comfort. A professional load calculation considers your home’s insulation, size, and window type to ensure perfect sizing. 4. Advanced Features Look for two-stage burners, variable-speed motors, and compatibility with smart thermostats for better control and quieter operation. Some Orillia homeowners may also qualify for rebates when installing high-efficiency systems. Frequently Asked Questions How do I know it’s time to replace my furnace? If your unit is over 15 years old, struggles to heat evenly, or your bills keep rising, replacement is likely more cost-effective. Is a high-efficiency furnace worth it? Yes. It lowers monthly costs and provides steady, comfortable heat throughout Simcoe County winters. Can I install a furnace myself? No. Professional installation ensures safety, compliance, and warranty protection.

How to Prep Your Furnace for Summer in Orillia

July 3, 2025

Your furnace may get a break during the summer, but that doesn’t mean you should ignore it. At Mr. Heat Furnace Repair Orillia, we recommend taking a few simple steps to shut down your furnace properly so it stays in good shape for the next cold season. A little care now can prevent problems—and save you money—later.


Why Shut Down Your Furnace for Summer?

Even when you’re not using your furnace, dust and moisture can build up and cause wear. Taking the time to clean and prep your furnace helps:

  • Prevent damage and rust
  • Save energy
  • Extend the life of your heating system
  • Catch small problems before they turn into big repairs


5 Simple Steps to Shut Down Your Furnace

1. Turn Off the Pilot Light or Power
If you have a gas furnace, turn off the pilot light to save energy. For electric furnaces, flip the power switch on the unit or shut off the breaker to cut power.

2. Change the Furnace Filter
Even in the off-season, a dirty filter can affect air quality and clog the system. Swap it out now so it’s fresh and ready for fall.

3. Clean Around the Unit
Vacuum dust and wipe down the outside of the furnace. Clear away any boxes, furniture, or clutter near the unit to help airflow and safety.

4. Check for Leaks or Strange Smells
Look for signs of moisture, rust, or a musty smell. If anything seems off, give us a call for a quick inspection.

5. Schedule a Pre-Fall Tune-Up
Book a furnace inspection in Orillia before fall arrives. Our local HVAC experts will make sure everything is working right so you’re not caught off guard when the cold weather comes back.
