Question DetailsAsked on 11/29/2015

A/C repair, Las Vegas, NV, A/c Unit will not turn off. Had to turn circuit breaker off to get it to stop.

Because I had to turn the circuit breaker off my heater will not work upstairs. How serious is this problem?

Could be anything from a defective limit switch to a bad thermostat to being low on refrigerant due to a leak so the unit never got the house down to the temp required for the thermostat to shut it off. So cost could be anything from a service call and small part (maybe $100-200 total) on up to complete replacement (several thousand $ at least) if an older unit and it makes more economic sense to replace than to fix due to a major failure.

One thing to be ready to consider - if an older unit and especially if Freon (R-22) based, with Freon being phased out (due to environmental laws) it can sometimes cost $500 or even more just to refill a leaked off unit so adding a repair cost on top of that can sometimes weigh heavily in favor of replacing an older unit with only a few years of life left (say anything probably 10-15+ years old) with a new unit with the new type gas (usually R-410a) and a warranty. You can do some reading on that issue in the Home > HVAC link in Browse Projects (at lower left) where there are a lot of similar questions to yours with answers about repair versus replacement. Of course, till the diagnosis is done you won't know if this is a simple repair or a terminal unit, but you should be prepared to address the possibility.

Check around the A/C - on the housing, on wall near it - there should, if wired legally, be a breaker or shutoff just for that unit, which if you find and shut it off would then allow you to turn the breaker back on that shut off the heater. This assumes you are talking a separate heater - not that the HVAC unit is a heat pump that both cools and heats depending on demand.

If the heat is a critical thing you could call out an electrician (expensive on weekend - probably $200-250 range) to temporarily disconnect the wiring on the A/C till a Heating and A/C tech can come look at it.

Heating and A/C is of course your Search the List category for finding a technician to look at the A/C.
