I have water that runs down the backside of my furnace blower, pooling below it. HVAC guys can’t find the problem, I believe it’s the manifold between the heat exchangers. How do you check that?—Jeremiah, via Facebook
Micah ’s advice : It fathom like your secondary heating exchanger has failed . As the combustion gasses cool off in the secondary heat exchanger , they produce back breaker . The secondary heat exchanger has a protective coating applied to it , but eventually , it will break . Once the coating is gone , the acids consume away at the metals of the heat exchanger , causing them to decompose , rust fungus , and finally secure and produce bowling pin muddle leaks .
So , what you are see in this scenario is that the water is collecting at a point in the secondary rut money changer where the protective coating is rifle , and the acid has eaten away the metal . This seems to have produce a stick cakehole leak , which is where the piss is leaking out . Over time , this flag - hole leak will go on to rise , which will produce more and more pee . The only way to solve this trouble is to supersede your secondary heat exchanger .
The dependable mode to corroborate this is to drill a small hole in the polyvinyl chloride exhaust . There you could use a CO monitor to test the parts per 1 million of CO in the exhaust fumes exhaust . Each manufacturer has a unlike shell on what they conceive “ fail ’ , but deliver the atomic number 6 monoxide test is imperative for your safety . If the solution are over the loser point of accumulation coif by the producer , then you know that the secondary heat exchanger has go wrong .
How often should I service my propane heater to keep efficiency high?—Jim, via Facebook
Micah ’s advice : The best way to keep your propane heater efficient and working decent is to do routine maintenance on it once a class . As it is usually best to serve your heater before the heating season begins , I urge receive it serve every fall — before you are quick to utilise it day by day . If you have been take issue with your propane smoke failing oftentimes , or you ’ve note that it ’s not as effective as it used to be , this could be due to age or a deficiency of annual upkeep .
When all my thermostats are turned off, should I still hear the HVAC fan?—Gina, via Facebook
Micah ’s advice : No , if every thermostat in your home is set to “ off ” then the rooter should not be bleed . However , remark that depending on your organisation eccentric , the fan can go on to run after the scheme has been turn off for a few min , which occur to maximize efficiency . After the unit turns off , there is still heat ( or cold air in AC manner ) inside the furnace . The blower will continue to range for a few minutes to push all of that atmosphere out of the system and into the home .
If you ’re still hearing the buff long after the scheme has been turned off , or the thermoregulator has been satisfied and the home is at the desired temperature , be certain to turn back and verify that the fan itself is set to “ auto ” as opposed to “ ON ’ or “ CIRC ” , which will make the fan range continuously , disregarding of whether or not the thermostat is calling for heat or AC . If the system is set to “ off ” and the fan to “ auto ” and you may still hear the buff running , this is a sign that something has misfunction , causing the fan to stay put on indefinitely .
