Gas Furnace Review: Choosing Your Next Furnace

If your furnace experiences problems or just quits working altogether, you are faced with a troublesome choice: Do you attempt to repair the broken part, or purchase an entirely new system? The very first matter to consider when faced with this question is the era of your current gas furnace. If it is older than 10 years, chances are there have been progressing in efficacy or industry standards that you can benefit from in the event that you replace your own system.

Frequently, Applewood Air HVAC professionals recommend that you upgrade or replace your existing gas furnace when you replace your central heating unit. This is a great way to save money with time, as a high-efficiency furnace and a cooling system that’s exactly the same age and brand work better than a mismatched-efficiency pair of an older furnace and new AC unit. Sadly, this is not always a feasible option fiscally, as high-quality HVAC units can be costly in the tens of thousands. If your current furnace’s era is within five decades of the new AC unit, it ought to work well with your new cooling unit.

Ultimately, it’s up to you in the event that you would like to replace your furnace. To help you decide, consider the present efficiency of your home furnace, its age, and if you’re inclined to replace a part that may continue to fail in the years ahead. Oakville New Furnace & AC Installation & Repair

Gas Furnace Efficiency: Why It’s Not Just About the Money

Size Matters

Unlike many important appliances which get better in functionality as they increase in price and size, furnaces need to be the ideal size for the design of your home. This means that buying the most significant and most energy-efficient furnace on the market is usually not the best answer for your home.

Every house is different, whether in its design, venting system or materials. A natural gas furnace that is too small will not have the capacity to create adequate heat in the winter or push enough cool air in the summer. Conversely, a system that’s too big for your house will cost more to operate and not efficiently maintain correct temperatures.

Energy Efficiency

If your gas furnace was installed in your house over 15 decades ago, you’re pretty much certain to be heating your house inefficiently. With a high-efficiency furnace, the quantity of gasoline you need to warm your home declines, just as do the charges on your utility statements.

When choosing the very best furnace, consider the device’s yearly fuel utilization efficiency (AFUE) rating. This amount is represented as a percent and indicates how much heat a furnace can obtain from each cubic foot of gas. To clarify even more, for instance, an AFUE rating of 96 percent means that around 96 cents of every dollar are utilized to warm your house. The federal benchmark for cheapest allowable efficiency is 78 percent, and lots of contemporary units reach upward of 98 percent.

Everything You Need to Know About Furnace Setup

A furnace is a significant home improvement investment, so any knowledge you’ll be able to equip yourself with before determining which new unit to purchase can help save you money and time in the long run. Below are some essential components of forced air heating you will need to be aware of as you talk to your regional HVAC professional.
Kinds of Gas Furnaces

Gas furnaces come in two varieties, single-stage and two-stage. Single-stage furnace blowers use a single-speed blower, which switches off and on until it reaches the desired temperature. These furnaces are usually older models, but it’s still possible to purchase one for the home which has an AFUE of 80 percent.

While these units may be a less expensive investment initially, the decreased efficacy from switching on and off constantly ends up costing you more over time than a furnace with a variable-speed blower. That having been said, if you’ve got a bigger house, consult with your HVAC professional to determine whether a single-stage furnace would be a more viable option.

Two-stage gas furnaces work similarly to single-stage ones, but if the temperature drops and the initial stage is not generating enough heat, the next phase turns to enhance your home’s heating needs. This second stage allows your furnace to produce and use more heat with less effort and fuel. Another great side effect of a two-stage unit is that it generally runs much quieter than the single-stage models.

What Else Is Important When Selecting a Furnace?

Gas Engineers have other factors to consider beyond efficiency and installation. By way of example, furnace warranties vary between manufacturers. Annual maintenance and reliability are also important to consider.


The lifespan of your furnace is influenced greatly by how well you, the proprietor, perform routine maintenance. This doesn’t mean you have to know how to fix and reconstruct a furnace unit, only that you ought to be able to perform basic maintenance tasks such as changing and properly installing air filters, so keeping the airflow path without any obstacles, and giving the major unit a visual inspection a couple times per year.

Air filters are one of the most important elements of an efficient gas furnace. While older designs and cheaper furnace filters block large particles, they do not remove small particles such as pollen in the air that circulates throughout the system.

Luckily, you will find high-efficiency filters that you are better off using, particularly if you have allergies, reside in a dusty area or have pets that shed. While the high-efficiency filters cost more, the number of particles they remove from the atmosphere will help you and your furnace breathe easier.

High-efficiency filters will need to be changed approximately every three weeks, but you might need to replace them more often if you have several pets or someone who smokes in your house. While three months may seem quite often, if you employ cheap, thin filters, you need to replace them every month, as they don’t take so long to reach capacity.

Keep the area around your furnace totally free from obstructions, such as boxes, that could block air circulation. The burner inside your gas furnace wants to have enough oxygen to function properly, and a reduced air intake could be dangerous also cost you more money. Additionally, a couple times during the calendar year, take a quick visual assessment to find out if anything seems wrong, such as loose wires, bent panels or any venting pipes which need repair. Simple maintenance chores such as these can help keep your furnace in tip-top shape for years as well as your household toasty during the winter months.
