Is It Time to Replace?
Common Signs You Need Furnace Repair
Don’t ignore the warning signs. If you notice any of these common issues, it’s time to call CORH for professional furnace repair in Collingwood before a minor glitch leaves you freezing in the middle of the night.
Short-Cycling or Constant Running
Is your furnace turning on and off every few minutes, or running around the clock without actually warming the house? Timing issues like this usually point to a faulty flame sensor, restricted airflow, or an overheating safety switch.
Sudden Spikes in Heating Bills
A broken or struggling furnace has to consume significantly more gas just to do its basic job. If your winter energy bills are suddenly skyrocketing, a professional repair can restore your system's efficiency and stop the financial drain.
Frequent System Breakdowns
Keep having to make service calls for temporary fixes? If you are constantly on the phone trying to get your heat working, it's time for a proper, lasting repair. We diagnose the true root cause so you aren't stuck dealing with back-to-back breakdowns.
Uneven Heat & Cold Rooms
If the living room is roasting but the bedrooms are freezing, your system has an airflow or distribution problem. We can repair failing blower motors or address ductwork issues to restore balanced comfort to every room in your home.
Strange Banging or Squealing Noises
Heating systems shouldn't be loud. Squealing belts, grinding metal, or loud booms when the system turns on are major mechanical red flags. Turn the unit off and call us to fix the problem safely before it causes permanent damage.
Constantly Having to Add Heat
If you find yourself constantly pressing the "+" button on your thermostat but the house never actually reaches that temperature, your system is losing its heating capacity. We’ll repair the burners, pilot, or gas valve to restore full heating power.
How Prompt Furnace Repair Lowers Your Energy Bills
When your heating system has worn parts or restricted airflow, it has to work harder to keep your home warm. That wasted energy can raise monthly gas bills and reduce comfort. With timely furnace repair in Orillia, CORH helps restore efficiency by fixing issues like failing blower motors, faulty sensors, and airflow problems, keeping your furnace running properly while helping control winter heating costs.

Frequently Asked Questions
HOW LONG DOES A TYPICAL FURNACE REPAIR TAKE?
Most standard repairs take about 1 to 3 hours. CORH technicians arrive in fully stocked vehicles with common replacement parts, so we can complete your furnace repair in Orillia on the spot whenever possible.
When should I replace my furnace instead of repairing it?
A good rule of thumb is the "50% rule." If your furnace is over 10-15 years old and the repair will cost more than half the price of a new unit, replacement is likely the better investment. Our technicians will always give you an honest, no-pressure assessment.
WHY IS MY FURNACE BLOWING COLD AIR?
This is one of the most common issues we see. It could be as simple as a thermostat set to "On" instead of "Auto," a clogged air filter, or a dirty flame sensor. If changing the filter doesn't help, it's time to call us for a professional diagnostic.
DO YOU REPAIR ALL FURNACE BRANDS AND MODELS?
Yes! Our certified technicians have the experience and training to troubleshoot and fix all major heating brands, including Lennox, Carrier, Goodman, KeepRite, and more.
Are your technicians certified?
Absolutely. Our team consists of fully licensed, insured, and highly trained HVAC specialists experienced in Simcoe County's specific climate needs.
DO YOU GUARANTEE YOUR REPAIR WORK?
We stand completely behind our workmanship. Every furnace repair we complete comes with a solid labor warranty, in addition to any manufacturer warranties on the replacement parts we use, giving you total peace of mind.
