3 Things To Consider When Replacing Your Furnace

Posted on

The furnace is an important part of your home. Not only is it necessary for absorbing cold air and improving air quality, but heating is also essential for keeping your family comfortable during the cooler seasons.  Unfortunately, you may not realize your furnace is not heating in the most effective and efficient manner. On average, today's furnaces have an expected lifespan of between 20 and 30 years, so you may need to replace yours at one point in time. With this guide, you will learn a few things to consider before replacing your furnace.

Size

In many cases, an HVAC technician will suggest replacing your old furnace with a newer unit that offers the same size capacity. This may seem like the easiest option, but more thought and calculations should be conducted because the size of your furnace does matter if you want to heat your home efficiently.

Your HVAC contractor should perform a load calculation, which determines the best size for the most efficient and effective heating capability.

Load calculations use your home's square footage, layout/floor plan, and local climate to find the right size for the specific needs of you, your home, and your local environment.

Heating Source

After deciding on what size is right for you, technicians will offer a few furnace options.

For the most efficient and affordable heating when temperatures are at or below freezing temperatures, opt for a natural gas furnace. Oil and propane furnaces are also available, but these furnaces are larger, taking up more space in your home. They can also be hazardous to the environment since they pollute the air and harm your indoor air quality.

Electric furnaces are also options to consider. They are also the most traditional furnace found in homes. Unfortunately, they do require a good amount of energy, so you will most likely see a large increase in your monthly energy bills.

Variable or Fixed

The main source of heat is an important factor to consider, so after weighing out the pros and cons of natural gas, oil or propane, and electricity, you need to decide on whether a variable speed or fixed furnace is ideal.

When temperatures are lower outside, the furnace fan should blow faster, circulating warm air more effectively in the home. When temperatures are warmer, the fan should slow down because you will not need as much heat. To ensure your home is heated in this manner, which is more efficient, you need a variable speed furnace.

If you choose a fixed speed furnace, the fan will only turn on and off according to how your thermostat is set.

Proper understanding and a heating contractor will help you find the right furnace for your home. Then, you will be able to heat your home with ease.  To learn more, contact a company like Brian's Heat and Air.
