    Talking Smoke detector goes off when heat is turned on.

    So I've already called a professional and turned my heat off immediately to prevent a compressor burnout of any other problems. I just rented the home in october (in arizona) and the AC is running fine. It's been cold lately in the home so I just thought I'd test out the unit to see if it would run in heat mode, ya know to see if any maintenance was needed so my AC would run efficiently next summer(since I'm from the east coast I generally dont need heat out here). Well I turned it on, took about 2 minutes to kick on, started smelling something then the smoke detectors went off. Personally I would like to take a look at the unit since im in school right now for HVAC, but I havent learned enough yet to tackle the situation fully. I'd like the job to be done right so I made a call since the bill is covered by the homeowner anyways. Im not asking for any help on how to fix it, but what are some of the possible causes. Any insight would be appreciated and benefit my education.

    Could be something as simple as dust/dirt on elements if it's electric heat. You took the best course of action, let a pro look at. Good luck with your schooling!

    That happens every year when the electric elements come on for the first time and burn off the collected dust, or if its a brand new gas furnace there is manufacturing oil on it that burns off the first time it's fired, best to have it looked at anyway.
