Top 6 Energy Efficient Brands for Gas Furnace and Boiler

Everyone wants to install the best brands of HVAC. Following are the top 6 energy efficient brands you may want to know about, before you contact a heating contractor.

  1. Amana

Gas furnaces can be termed as efficient, only if their annual utilization is a minimum of 78 rating. But modern furnaces like Amana achieve nearly perfect rating with its patented technology, tubular design and innovative parts by lasting for a minimum of 10 years. This high-quality stainless steel furnace has dual-heat exchanger and a circulator motor with variable speed that can maintain temperature settings. The SureStart Silicon Nitride Igniter present in Amana can endure repeated usage. It has the highest standards of operating at 95% AFUE rating, which reveals its high efficiency.

  1. York

Only few choices of furnaces like the York are apt for both commercial and residential use, irrespective of whether your furnace is propane-based or gas-based. The model features 2-stage heating, self-diagnostics, quiet running, the capability of maintaining an even temperature and an extremely comprehensive design. It is best for homes with extreme temperature and is most efficient when used in low settings and has 96% AFUE rating. Thanks to its efficient electronic ignition system, it can save considerable fuel. The in-built sensors aid the licensed heating contractor to easily identify and repair issues related to fuel intake, heat exchange or ignition.

  1. Trane

It is perfect for a studio or small-sized home, office or apartment, which typically measures around 700 sq. ft. It possesses a good AFUE rating on energy efficiency and is a cost-effective and comprehensive solution. Though it has a limited size and capacity, the single stage burner and single speed blower enables speed variations in the furnace so that your home enjoys an evenly maintained temperature for a long time. To compensate its inadequacies of smaller size, average efficiency and limited capacity of heating, three types of warranties are offered for Trane. This includes a 20-year warranty on heat exchanger; 10-year warranty on the parts; and an overall warranty of the device for 10-years.

  1. Goodman

What sets Goodman to standout in the list of high efficient modern furnaces is the durability of its parts. This model offers the best combination of minimum input and maximum output, which essentially means minimum gas consumption and prolonged working. No wonder it possesses 95% AFUE rating. Its salient features include variable speed blower, 2-stage burner, patented TuffTube with dual diameter, lifetime warranty, silicon nitride igniter, quiet and direct-drive motor and best in lowest settings. This model is best for homes having a floor area of 2000sq.ft. what’s more, you get a 10-year warranty for the entire furnace replacement.

  1. GE (General Electric)

Geospring Electric Heat Pump could be your choice if you wish to have a good and simple model that boasts of optimum energy efficiency. Being one of the first water heaters for residential use, the GeoSpring Hybrid Water Heater offers 4 modes of settings, based on your situational requirements. The settings include:

  • At Heat pump mode, the heater uses only the heat pump to heat water. This is the best and high-efficient mode.
  • Hybrid mode gives you fast recovery and low energy usage. This mode uses heat pump and as per demand, uses the usual electrical elements temporarily; it reverts to heat pump usage once the desired temperature is met.
  • Boost or High Demand mode is perfect for large quantity of water heating. Here, the operation is similar to hybrid mode with an added feature of faster recovery time.
  • The Standard mode is the best for very cold situations (where the temperature is lower than 35oF). This mode mainly uses electric elements to heat water.
  • Vacation mode is the best feature of GeoSpring Electric Heat Pump, which saves huge amount of energy once set. It also prevents freezing of water and lets you to have a set point of 50oF. This model allows you to also set the number of days to start the device.


  1. Carrier

Carrier perfectly fits in the list of high-efficiency furnaces, as it scores 96% in efficiency ratings. The special feature includes a configuration of up flow and down flow with flexible installation. This is perfect for an average comfort requirement. The variable speed motor, dual-stage burner and 2-heating levels are some of its special features. Nevertheless, this model has aluminum heat exchanger, which could be have slight disadvantages over the steel in terms of durability. But this is compensated by the long lasting ignition system.

A licensed and well-established HVAC contractor in Colorado would be able to guide you to pick the best one amongst these for your home or office needs.

Most "BOXes" are the same  Most motors are the same maker, 98% of TXV's come from the same maker.  I look at sound, AFUE, how long it lasts, ease of maintaining the "box", training, support.   there is 21 levels of motors same frame size,   Take coils 2.5 ton the air flow can go from .17 SP to .55 SP inch of water.   Duct work and way it put in This has more to do with total system eff than the "box"

Thank you for your valuable comment Gary.

Yes, the product AFUE rating and other numbers are from company's info.  Also, I tried to cover the user experience too. If you want to know about the common furnace problems please visit here.

Great article! We supply mostly Carrier, but these other brands are also great. You're not lying the the long lasting ignition systems. Did you get this info from the company's? It would be nice to be able to "road-test" them side by side to see how they actually hold up. Great info though!
