Gas Furnace Installation

There are many types of heating systems for your home out there but a gas furnace is one of the preferred choices.

A furnace is a heating system that burns natural gas to warm up a heat exchanger. With the exhaust fumes removed through a flue gas vent, the heated air is then circulated in your home with the help of a blower fan.

This effective heating system is continuously improved with time. Apart from heating your home consistently and adding value to your home, nowadays furnaces can even control humidity and air quality.

At Protech Inc, you can purchase a modern furnace that will guarantee your comfort while caring for your family and budget. Shop for your brand new furnace today!

How To Choose the Best Furnace for your Home

At Protech Inc, we offer numerous furnace models and brands. With so many choices available you may be wondering how you’ll be able to choose? 

Even though we have tons of high-quality alternatives, you need to assess which one is the best for your needs. These simple guidelines will help you match your purchase with your specific requirements.


A furnace’s efficiency depends on the AFUE (Annual Fuel Utilization Efficiency), a ratio between the fuel burned and the fuel converted into heat. The higher the efficiency percentage, the more gas, and money you will save because you’ll be obtaining more heat out of the fuel burned. 

Nowadays, a furnace with an AFUE below 92% is considered obsolete but you’ll want to contemplate how long you’re going to be staying at your home. If you are staying for a long time, we say the higher the AFUE the better.


A furnace can have one or multiple stages. The stage number represents the number of burners and gas valves a furnace has.

The number of stages in your furnace affects the amount of gas burned and your heating costs as well as the temperature’s consistency in your home. 

With a single-stage burner, you can’t regulate the heat consistency. A two-stage burner can be operated at a lower capacity, running at a reduced speed. To have even more control over the heat consistency, a modulating-stage furnace is a great option, especially if you’re staying in your home for a long time.


The furnace’s speed doesn’t only depend on the stage, it also refers to the furnace’s blower. There are two options for speed which are variable and non-variable.

The standard non-variable furnace blower comes with four speeds: low, medium-low, medium-high and high. On the other hand, a furnace with variable speed will run according to the load of the home and the outside temperature. Undersized or obstructed ductworks will benefit from a variable speed furnace.

We hope these simple but crucial major points are helpful for you. If you still have any doubts, don’t hesitate to reach out to us.
