Word of Mouth
Comments on HVAC-Talk message boards and heating contractor sites are rather critical regarding
certain parts of Bryant Furnaces:
- Bryant has had absolutely no problems whatsoever over the past 20 years, according to a
guest at the HVAC-Talk forums, but the compressor keeps failing. Poorly installed or designed
wiring affects part-performance.
- With other Bryant units, a couple of others at the HVAC-Talk forums insist that the problem
involves the pilot, not the compressor. As a result, the flame either won't go on or
immediately goes out after ignition
- Bryant's five-wire valves are confounding and troublesome, according to one service tech
at the HVAC-Talk forums. Pilot activation, which is essential for the heater or boiler to work,
is hindered, and therefore no flame can be lit. Bryant's wiring makes maintenance and repair
all the more difficult in the process.
Warranty
Bryant furnaces come with a 5-year limited warranty on all parts. The heat exchanger, however,
has a 20-year limited warranty.
