What is the Difference Between 1 and 2 Stage Furnaces?
1-stage and 2-stage furnaces refer to the number of heat output levels the furnace has and how it operates to regulate indoor temperature.
Here's the difference between them:
1-Stage Furnaces: These furnaces have only one level of heat output, which is typically high.
When the thermostat calls for heat, the furnace fires up at full capacity until the desired temperature is reached, then it shuts off.
They operate in an all-or-nothing manner, meaning they are either on at full blast or completely off.
This can lead to temperature fluctuations and less precise control over indoor comfort.
1-stage furnaces are generally less expensive upfront compared to 2-stage furnaces but may result in higher energy bills due to frequent cycling on and off.
2-Stage Furnaces: These furnaces have two levels of heat output: high and low.
When the thermostat calls for heat, the furnace first activates at a lower capacity (low stage) to maintain a steady temperature.
If additional heat is needed to reach the desired temperature, it switches to the higher capacity (high stage).
They provide more precise temperature control and reduce temperature swings because they can operate at a lower output level for longer periods, maintaining a more consistent indoor temperature.
2-stage furnaces are typically more energy-efficient than 1-stage furnaces because they can run at a lower capacity for longer periods, consuming less energy overall.
Although 2-stage furnaces are usually more expensive upfront compared to 1-stage furnaces, they can potentially save money on energy bills over time.
In summary, the primary difference lies in the number of heat output levels and how they regulate indoor temperature, impacting comfort, energy efficiency, and upfront cost.

Great Team! Furnace broke in the weekend, Bob visited same day and Greg installed new one on Monday. Team was professional, respectful and knowledgeable. Installation went very well, Greg found solutions to challenges, like hiding new conduits in the ceiling. Looks nice and new furnace is working great. Five Stars.
I used Twintech to install a new furnace for my home. Bob was terrific in explaining the sizing options and why the 2 stage furnace was the best option for me. Greg did a great job installing, clean and on time. Finished work looks great but the best part is how it works. The 2 stage heating is so much more comfortable. I run the fan continuously to keep the indoor air clean. Great investment! Would highly recommendTwintech!
Im going to start this by saying Im a very particular customer. My background is in mathematics and mechanical engineering so I have an eye for detail and a respect for technical knowledge.
Greg had already done an AC inspection and replaced a water heater tank and there was no question in my mind who to deal with replacing my rickety old furnace after it got pooched.
Bob dropped in ahead of time and clearly (and knowledgeably) outlined all technical, price and operational options.
Greg showed up on time, on the agreed date and did a fantastic job. (The OLD furnace was a house of horrors and was installed in a keystone cops sort of way- careless.)
The work Greg did was HIGHLY PROFESSIONAL and FAR MORE FUNCTIONAL than what I had.
Im also a musician with many instruments so maintaining predictable humidity/temperature is extremely important to me. Greg recognized this as did Bob. You NEVER feel like youre being brushed off.
In summary, if youre looking for PROFESSIONAL, QUALITY results by an EXPERIENCED, THOUGHTFUL team
(that also happen to be FRIENDLY and ATTENTIVE ) then youve come to the right page!!
Once again Twin Tech came through and fixed my furnace. A young man by the name of Mitch came by tonight and he was so nice explained everything he was quick he was clean he turned off the lights even when he left the furnace room its just above and beyond Twin Tech always delivers and I just found out about them last year and I will use no one else but thanks again Mitch you are fantastic
I had a problem with the Furnace (Armstrong ultra V) and Greg diagnosed it on the phone. Even told me what the issue was and I was able to fix it. This level of service from a Business that is almost unknown today.
If you require service, reach out to Greg. I will definitely use them in the future!
We have been shopping for a heat pump for our home. We had 3 reps come in and make recommendations and provide a quote. Of the 3, Bob was so clearly so much more qualified, thorough and informed than the other two that the decision was a no brainer. As soon as we get our audit results Twintech will be installing our heat pump.
knowledgeable sales person, did not try to up-sell unneeded features,
and was easily contacted to ensure customer satisfaction.
Installation was expertly done by friendly guys, everything explained for use of the products. Old products were removed and returned to rental company as part of the service. Follow up call was received to check all was well. This is my second time using this company as I was fully satisfied with my previous air conditioning unit installation
Twintech recently installed a new furnace for me. Bob did a great job assessing what I had and needed. All details well explained including the importance of proper sizing of furnace and the value of multi stage heating and the variable speed blower. As a nurse, indoor air quality is a high priority so the variable speed motor running continuous is so good. 24/7 air cleaning. Greg did a great job on install, attention to detail so appreciated. Already notice such an improved comfort and heat. Thank you Twintech! You come as advertised. I will recommend to anyone in need of heating or cooling!
We received various quotes from 4 different companies and right away, the prompt and thorough communication from Bob from TwinTech stood out. He introduced himself, sent sample sites and information, and always confirmed any agreed to dates and times.
Bob was friendly and extremely knowledgeable about the topic of HVAC and it was clear he was passionate about his profession. He approached the job as if he was installing in his own home.
Prior to the new furnace & A/C installation, our old units were loud and inefficient - having several rooms feeling too cold in the winter and too hot in the summer. After installing the recommended units, all rooms stay at a consistent temperature- even the finished basement.
I highly recommend the TwinTech team - just an outstanding job at a reasonable price point.
The experience with Twintech was great from the start. Bob the sales manager was friendly and professional and did not use any pressure tactics. He was very knowledgeable.
The installation was completed by the twin owners in about 6-7 hours. Clean quiet easy going didn't mind when I poked my head in to see progress. Highly recommend
