Word of Mouth

Comments on HVAC-Talk message boards and heating contractor sites are mixed regarding certain parts of the Bryant Furnaces:

• One person at the HVAC-Talk forums claims to have had no problems with the Bryant unit or replacement of any parts in 20 years. But the compressor keeps going out for apparently no reason. Perhaps this problem is associated with poor or complicated wiring that sometimes interferes with the functioning of certain parts.
• Two other people at the HVAC-Talk forums concur. In their particular cases, however, the wiring interferes with the pilot light's performance, which, in turn, prevents the flame from igniting or causes the flame to extinguish right after starting.
• One professional tech at the HVAC-Talk forums clarifies that Bryant's five-wire valves tend to be aggravating because they interfere with pilot performance.
