Hello, I hope I am in the correct forum here. I am not here for DIY info, as I can see is against the rules, because I live in a rental property and maintaining the furnace/ac is not my responsibility. However, my property manager insists my furnace is working as designed and will not have it looked at. She insists that the maintenance man(supervisor?) just needs to come out and explain the way the furnace works. Before I get in to details here is some pictures of the unit and some information:
Model Number and Tech Info
Picture of the unit:
I called the property manager about 2 weeks ago to report a number of issues that sprung up at once. I said the furnace seems to be running much harder then it should be. However, some times it may only kick on for 15 seconds, kick off. Then 5 min latter, kick on for 15 seconds, then kick off for another 5 min, and may repeat this a few times in an hour. Most of the time it is putting out room temp and at times even cold air. The other thing I noted is that most of the time, when the furnace is about to shut off, it makes a sort of hissing noise. The way I describe it to people is that it sounds like an air valve popping off similar to air brakes on a semi when they blow off excess air. She insists that these units are, more or less, unconventional and do not need to put out warm air to actually heat our town house.
Anyway, I hope I have kept this short but detailed. Is it time to call an HVAC repair man and send the property manager the bill?
