Horrible furnace

We replaced the original Bryant furnace with this unit number in 2012. Already have to replace again in 2018. This is unacceptable and this company should have a lawsuit filed. 340Aav036080 was model number And we have to go with another Bryant due to plumbing and duck work :(. Without heat for 2 weeks now. Thank god for space heaters. Itís been brutal cold

No Heat

Have experienced several problems in the six year period with this furnace. These include two emergency calls to diagnose problems which totaled over $300. One problem was the pressure switch needing replacement. Then the inducer motor failed after three years. Now we have been diagnosed with needing a new secondary heat exchanger. We have been advised that we may need to pay for the labor costs which could be as high as $1200 (6-8 hours). When I called Bryant's customer service, I was told that they typically do not pay labor costs to replace the heat exchangers (secondary or primary). This all seems very unfair to us to say the least!

Poor Quality

Motor replaced at year six. Plus numerous other problems since new. Air Conditioning also a problem and replaced entire unit with new/different brand. Do not recommend Bryant and will never buy Bryant again.

Terribly unreliable

This furnace has been in my new house for three years now, and is on its third completely unique total failure (different part ruining it each time). Absolutely junk. If you like repairing your unit every season, then this furnace is for you; otherwise, stay far, far away.

Bryant is not reliable

Our home is brand new and they installed a Bryant furnace and air conditioner. We live in Michigan. This is our second summer (cooling season from June to August) owning this unit. Our TXV already went bad on our Bryant. Bryant couldn't care less. The labor cost is around $300. Our Lennox furnace and air conditioner never had any problems at our old home! We owned them for over 15 years before we sold the house and it always worked just fine. Buyer beware! There is a difference! Service calls/labor is expensive! Do you really want to deal with a company that treats their customers like crap and pay out of pocket costs every year for labor!

We live in a D.R. Horton home built in 2011. This furnace was brand new and has been nothing but problems. First it didn't run at all, but luckily was under warranty. Now, a year later it has quit working in the middle of winter and we have spent $1500 trying to repair it. It worked for one day and today has quit again. I would not recommend this furnace to anyone and I hope D.R. Horton chooses another vendor from which to purchase these units.

Other 340AAV Reviews

The Bryant 340AAV is subject to mixed reviews from forums across the web. While most contractors recommend the unit and other Bryan heating products, consumer forums such as post several troubleshooting issues. Problems include instances where the furnace only blows cold air, failure to light and failure of interior components including the pressure switch or blower.

Despite the operational issues, many contractors on and have a positive view of this unit and believe it will provide quality performance with proper care and installation. However, some of these professionals mention it may be worth spending a little more to upgrade to a model with variable-speed functionality for more long-term efficiency and cost-effective performance.

Flashing yellow LED light on a Bryant 340 MAV


According to the owner's manual a continuous light from the yellow LED means that your furnace is operating in high heat. However, if it is flashing there should be a number next to the yellow flashing light. This number is the error code and will give you and idea of the source of the problem.
