Question 1

Does adding a second furnace zone require a permit?

Accepted Answer

Adding a second furnace zone typically does not require a TSSA permit in Ontario, as you're modifying the ductwork and controls rather than the gas appliance itself. However, electrical work for new thermostats and zone controls may require an electrical permit from the City of Ottawa.

Zone systems work by adding motorized dampers in your ductwork that open and close based on individual thermostat calls for heating or cooling. This allows different areas of your home to be heated to different t

Question 2

Who is responsible for pulling the HVAC permit?

Accepted Answer

The HVAC contractor is responsible for pulling the permit, not the homeowner. Licensed HVAC technicians handle all permit applications as part of their service, since they have the proper credentials and understand the technical requirements.

When you hire Ottawa HVAC Pro for furnace installation or gas fireplace work, we take care of the entire permit process. This includes submitting the application to TSSA (Technical Standards & Safety Authority), paying the permit fees, and scheduling the r

Question 3

Is a permit needed to replace a hot water tank?

Accepted Answer

In Ottawa, a permit is typically required for hot water tank replacement, especially for gas-powered units. The specific permit requirements depend on the type of water heater and the scope of work involved.

For gas water heaters, you'll need a TSSA (Technical Standards & Safety Authority) permit since this involves fuel-burning equipment. Only licensed G2 gas technicians can legally install, replace, or modify gas water heaters in Ontario. The permit ensures the installation meets safety codes

Question 4

What is a G1 gas license and why does it matter?

Accepted Answer

A G1 gas license doesn't exist in Ontario's TSSA licensing system - this is a common misconception. The actual gas technician licenses in Ontario are G2 and G3 licenses, both issued by the Technical Standards & Safety Authority (TSSA).

G2 technicians can install, maintain, and repair gas appliances in residential and light commercial settings, including furnaces, water heaters, gas fireplaces, and other fuel-burning equipment. G3 technicians have additional training for more complex commercial

Question 5

What is a TSSA inspection

What safety features should a furnace have

Accepted Answer

Modern furnaces include several critical safety features designed to protect your home and family from carbon monoxide, gas leaks, and fire hazards. The most important safety components are the heat exchanger integrity monitoring, flame sensors, and proper venting systems.

Heat exchanger monitoring is crucial because a cracked heat exchanger can allow deadly carbon monoxide to mix with your home's air supply. High-efficiency furnaces often include pressure switches that monitor the heat exchang

Question 7

What is the Ontario Building Code requirement for furnaces

Accepted Answer

The Ontario Building Code (OBC) sets strict requirements for furnace installations to ensure safety and proper operation. All furnace installations must comply with OBC requirements and receive TSSA (Technical Standards & Safety Authority) permits before operation.

Key OBC requirements for furnaces include proper clearances from combustible materials - typically 6 inches from the sides and rear, and specific clearances above based on the manufacturer's specifications. The furnace must be instal

Question 8

What warranty should I expect on a new furnace

Accepted Answer

Most new furnaces come with a 10-year parts warranty from the manufacturer, plus a 1-2 year labor warranty from your HVAC contractor. However, warranty terms vary significantly between brands and efficiency levels, so it's important to understand what's actually covered.

Manufacturer warranties typically cover the heat exchanger for 10-20 years (longer on high-efficiency models), while other components like the blower motor, gas valve, and control board usually get 5-10 years of coverage. Premi

Question 9

Do I need a permit to replace my furnace with the same size

Accepted Answer

Yes, you need a TSSA permit to replace your furnace in Ontario, even when installing the same size unit. This is a legal requirement for all fuel-burning appliance installations, regardless of whether it's a direct replacement.

TSSA (Technical Standards & Safety Authority) regulations require permits for any furnace installation or replacement work in Ontario. The permit ensures the installation meets current safety codes, proper venting requirements, and gas connection standards. Only licensed

Question 10

How do I check for gas leaks

Accepted Answer

If you suspect a gas leak, your safety is the top priority - leave the area immediately and call Enbridge Gas at 1-866-763-5427 or 911. Never attempt to locate gas leaks yourself, as this work requires specialized equipment and training.

Natural gas has a distinctive "rotten egg" smell added specifically for safety detection. This mercaptan additive makes even small leaks detectable by smell. If you notice this odor anywhere in your home, especially near gas appliances like your furnace, water

What questions should I ask an HVAC contractor

Accepted Answer

Ask about licensing, experience, and detailed project scope to ensure you're hiring a qualified contractor who will complete your HVAC work safely and properly.

Licensing and Insurance Questions
Start with the most important qualifications. Ask if they're TSSA licensed (required for gas work in Ontario), request their license number, and verify they carry WSIB coverage and liability insurance. A legitimate contractor will readily provide this information and won't hesitate when you ask to see p

Question 12

How do I verify my HVAC contractor is licensed

Accepted Answer

In Ontario, you should verify that your HVAC contractor holds proper TSSA licensing for gas work and is registered with WSIB for insurance coverage. This protects you from liability and ensures the work meets safety standards.

TSSA License Verification is the most critical step. Any contractor working on gas furnaces, fireplaces, or other fuel-burning equipment must hold a G2 or G3 gas technician license from the Technical Standards & Safety Authority. You can verify their license status direct

Question 13

Is my furnace safe

Accepted Answer

Your furnace safety depends on several key factors including proper maintenance, ventilation, and carbon monoxide detection. Without inspecting your specific unit, I can guide you through the essential safety checks every Ottawa homeowner should know.

Age and maintenance history are the biggest safety indicators. Furnaces over 15-20 years old require more attention, especially if they haven't received annual tune-ups. A well-maintained newer furnace with proper installation is generally very sa

Question 14

What is G2 vs G3 gas technician certification

Accepted Answer

G2 and G3 are TSSA gas technician certification levels in Ontario that determine what type of gas work a technician can legally perform. G2 is the higher certification level, while G3 is more limited in scope.

G2 Gas Technician Certification allows technicians to work on all residential and light commercial gas appliances, including furnaces, boilers, water heaters, gas fireplaces, and gas lines. G2 technicians can install, repair, and service any gas appliance up to 400,000 BTU input. This is

Question 15

What are the signs of carbon monoxide from a furnace

Accepted Answer

Carbon monoxide from a furnace is odorless and colorless, making it extremely dangerous. The most reliable sign is your CO detector alarm, but there are other warning signs that indicate potential carbon monoxide production from your heating system.

Physical symptoms are often the first indication of CO exposure. These include headaches, dizziness, nausea, fatigue, and flu-like symptoms that improve when you leave the house. Multiple family members experiencing these symptoms simultaneously is

Question 16

Do I need a permit to install a furnace in Ottawa

Accepted Answer

Yes, you need a TSSA permit to install a furnace in Ottawa. This is required by law for all fuel-burning appliances in Ontario, and only licensed G2 or G3 gas technicians can obtain these permits and perform the installation.

This is required whether you're installing a completely new system or replacing an existing unit, as the electrical connections must be

Question 18

Where should I place carbon monoxide detectors

Accepted Answer

Carbon monoxide detectors should be installed on every level of your home, including the basement, and outside each sleeping area. The most critical locations are within 15 feet of fuel-burning appliances like your furnace, water heater, and gas fireplace.

Install detectors at least 5 feet high on walls or on the ceiling, as carbon monoxide is slightly lighter than air and will mix throughout the room. Avoid placing them directly above fuel-burning appliances, in bathrooms, or near windows and

Question 19

What happens if HVAC work is done without a permit

Accepted Answer

Working without required permits can result in serious legal, safety, and financial consequences that far outweigh any perceived savings. In Ontario, TSSA takes unpermitted gas work very seriously, and the penalties can be substantial.

Legal and regulatory consequences include fines ranging from hundreds to thousands of dollars for both homeowners and contractors. TSSA can issue stop-work orders, require complete system replacement even if the work was done correctly, and pursue legal action fo
