A Fireplace That Heats the Room and Looks Like It Belongs There
A gas fireplace does two things at once. It adds genuine supplemental heat to a living space and it changes the feel of a room in a way that no other feature quite manages. Done right, it looks like it was always part of the home. Done wrong, it becomes a venting problem, a gas connection liability, or a unit that runs poorly and costs more than it should to operate. GHQ Mechanical handles gas fireplace installations with the full certification and care the job requires. We assess your space, recommend the right unit type and venting configuration, handle the gas connection and full installation, and do not consider the job finished until the flame is running correctly and the room is heating the way it should.

Why Hamilton Homeowners Are Installing Gas Fireplaces
Gas fireplaces have moved well past the novelty category. For most Ontario homeowners they serve a practical purpose that justifies the installation cost several times over across a typical heating season.
Supplemental Heating
- Reduces the heating load on your furnace
- Provides cost-effective zone heating for frequently used rooms
- Can continue providing heat during power outages, depending on the model
Comfort & Ambiance
- Delivers comfortable radiant heat without the dryness of forced air
- Creates the heat and atmosphere only a real flame can provide
Energy Efficiency
- Modern direct vent gas fireplaces operate at high efficiency levels
- Sealed combustion systems prevent indoor heat loss through the chimney
Added Home Value
- A desirable feature for homebuyers
- Is able to enhance resale value, especially in family rooms and primary bedrooms
A professionally installed gas fireplace offers year-round value, combining efficient heating with the comfort and appeal of a beautiful focal point.

Which Type of Gas Fireplace Is Right for Your Home
Gas fireplaces come in several configurations and the right selection depends on your space, your existing infrastructure, and the way you plan to use the unit.
Direct Vent Fireplaces
- The most popular selection for modern homes
- Uses outside air for combustion and vents directly outdoors
- No chimney required
- Safe, efficient, and ideal for most residential installations
Natural Vent Fireplaces
- Uses an existing chimney or B-vent system
- A good option for converting wood-burning fireplaces to gas
- Requires chimney inspection before installation
Ventless Fireplaces
- No exterior venting required
- Highly efficient and effective for supplemental heat
- Must meet Ontario regulations and ventilation requirements
Insert Fireplaces
- Installed into an existing masonry fireplace opening
- Converts inefficient wood fireplaces into efficient gas heating systems
- A cost-effective upgrade for homes with existing fireplaces

Why Venting Is the Most Critical Part of a Fireplace Installation
A gas fireplace that is not correctly vented is not only an inefficient heating appliance. It is a health and safety risk. Combustion byproducts including carbon monoxide must be fully exhausted to the exterior on every firing cycle without exception. Here is what goes wrong when venting is not done correctly.
A gas fireplace is only as safe as its venting system.
- Improperly sized or routed vents can restrict exhaust flow and create safety risks.
- Vent terminations must meet clearance requirements to prevent exhaust from re-entering the home.
- Direct vent systems must be properly sealed to keep combustion fumes separate from intake air.
- Chimney liners must match the fireplace’s venting requirements for safe and efficient operation.
- Poorly sealed roof penetrations can lead to water leaks and long-term damage.
We install every venting system to manufacturer specifications and Ontario gas code requirements, guaranteeing proper clearances, secure seals, and safe fireplace operation.

How Much Does It Cost to Run a Gas Fireplace in Ontario
Running cost is one of the first questions homeowners ask when considering a gas fireplace installation. Here is the honest picture.
Gas fireplaces are an efficient and affordable way to add warmth to your home.
- Most residential gas fireplaces operate between 20,000 and 40,000 BTU/hr.
- A typical 30,000 BTU fireplace costs approximately 15–25 cents per hour to run at current Ontario natural gas rates.
- Regular use can help reduce furnace runtime through heating the rooms you use most.
Efficiency Matters
- Direct vent fireplaces can achieve efficiencies of 70–85%, converting more fuel into usable heat.
- Lower-efficiency units waste more energy and cost more to operate over time.
- Choosing the right fireplace can greatly affect long-term operating costs.
We explain the efficiency and operating costs of every unit we recommend, assisting you make an informed decision before installation.

Why Gas Fireplace Installation Requires a TSSA Certified Technician
Every component of a gas fireplace installation involves either a gas connection, a venting system, or both. Ontario law requires that all gas appliance installations be performed by a TSSA certified gas technician. Beyond the legal requirement the safety case is unambiguous.
- A gas connection at the fireplace that was not pressure tested can develop a leak that goes undetected in the wall cavity for an extended period
- A venting system that was not correctly assembled allows carbon monoxide to enter the living space without triggering a detector if the concentration builds gradually
- A firebox that was not correctly framed and clearanced creates a combustible material proximity risk that is invisible until a problem occurs
- A termination cap that does not meet clearance requirements from openings and adjacent combustibles creates a re-entry and ignition risk
- An installation that does not meet Ontario gas code can void your home insurance coverage in the event of a claim
Our technicians carry TSSA certification and follow Ontario gas code and appliance manufacturer requirements at every step of every fireplace installation.
