When it comes to choosing the best gas furnace there is one area where all consumers must pay close attention – energy efficiency! Gas furnaces depended upon to heat an entire home during periods of cold weather. During this article we are going to share a few of our top tips when buying a new furnace.

Choosing the best gas furnace is crucial to keeping your home comfortable, even on the extrem weather. Gas is the most common heating fuel and this article will explain what you need to consider when choosing a new gas furnace for your home.

What Makes the Best Gas Furnace?

Contrary to the beliefs of many people, furnaces are not all made equal. In fact there are numerous different types and models of furnaces that you could buy, which all function slightly differently and may produce a different end result when installed at your property.

Size

The furnace’s size and capacity must fit your home heating needs. A furnace that’s too small won’t keep your house warm during cold weather. A furnace that’s too big will cycle on and off more frequently.

To be sure of correct sizing and a proper installation, choose a qualified HVAC contractor who will take the time to calculate your heating needs according to an industry standard. A qualified and experienced contractor will ensure that the gas furnace you select is the proper size for your heating needs. And will also ensure that your system will installed properly.

1,200 sq. ft50,000 BTU
1,200 to 1,500 sq. ft55,000 BTU
1,500 to 1,800 sq. ft60,000 BTU
1,800 to 2,500 sq. ft70,000 BTU
2,500 to 3,500 sq. ft90,000 to 100,000 BTU

Energy Efficiency

The other step in choosing for the best gas furnace is to look for a model than has the EPA/DOE Energy Star. When you see the registered trademark Energy Star you can be sure that it is more efficient than other models. Therefore, anytime you see the Energy Star logo, you can rest assured that you are purchasing the best gas furnace for your home.

A new model of gas furnaces are becoming increasingly energy efficient, which makes them better for the environment. And the most important, it can reduce the utility costs. New modern gas furnaces display an Annual Fuel Utilization Efficiency (AFUE) rating, which is a measure of fuel efficiency. Gas furnaces with higher AFUE ratings typically cost more, but they can reduce the overall cost of heating your home.

Use the zone map to identify efficiency levels and the suggested AFUE rating.

Features

Variable Speed – A variable speed motor is another feature when looking for the best furnace. Since rather than operating continuously, it adapts to your needs and allows the furnace to produce just the right amount of heat to keep you and your family warm. Variable speed furnaces are also known to help manage the humidity level in your property, which can help to prevent a range of problems.

Two-Stage Furnaces – If it’s consistent temperatures that you’re looking for, you can’t go wrong with a two stage furnace. Single stage furnaces can cause temperature fluctuations in your home, where as the double furnace system that two-stage furnaces utilize offers much more control over the heat that is emitted.

Low Noise Levels – A new furnace is something you are going to have to live with for a considerable amount of time, which is why you should choose a quieter furnace.

Programmable Thermostat – To use your heating system even more efficiently, a programmable thermostat is another feature to look out. This feature allows you to program your home’s heating according to your own schedule to ensure your system won’t be used for a second longer than it really has to be.

Warranties

The other factor to look is the length of the warranties. It’s not all about the product itself when shopping for a new furnace; you also need to carefully assess the length of the warranty that is included.

A good benchmark is to look for a model that has a warranty that covers the heat exchanger for 20 years (the most expensive part to replace) and everything else for 5-10 years.
