My Air Conditioner Isn’t Working In My Sacramento Home. Now What?
As summer heats up, it's time for your air conditioning to come out of hibernation. It's easy to miss common AC problems when it's not too hot out โ but when the thermometer's flirting with triple digits, you'll notice fast.
So what should you do when your air conditioner isn't working the way it should? Some problems have simple fixes. If you've worked through the troubleshooting below and you're still having issues, call Ace Plumbing Heating and Air Conditioning for AC repair near Sacramento.
My Air Conditioner Won't Turn On
Start with your thermostat โ turn the temperature down a few degrees and see if the system kicks in. Next, check your circuit breaker, since a tripped breaker is one of the most common reasons an AC won't power on at all. If neither of those solves it, it's time to call us.
My AC Is On, But It's Blowing Hot Air
First, confirm your system is actually set to "cool" โ otherwise the fans can run all day and your house still won't get any cooler. Next, check your breaker, especially if your outdoor unit and indoor air handler aren't on the same circuit; if both aren't running, you won't get cool air. Finally, check your filters โ a clogged filter can keep a system from running at full capacity, and in some cases can even trigger a shutdown. If you're not sure how a clogged filter is affecting performance, our AC tune-up service covers exactly this kind of check.
Some Rooms Are Cooler Than Others
Freezing out one room while another barely cools is one of the most common AC complaints we hear. Start by checking your registers โ if they're closed or blocked by furniture, that room won't cool as quickly as the rest of the house. Next, check your windows and window treatments (blinds, shades, curtains); sunlight or outside air leaking in will keep a room warmer than the ones around it.

My AC Won't Stop Running (or Keeps Short Cycling)
Sometimes the opposite problem shows up: your AC starts and just keeps going, or it short-cycles โ repeated on/off cycling that has nothing to do with actually reaching the set temperature. Check your thermostat setting first; on an extremely hot day with a very low target temperature, your system will naturally run longer than usual. That said, this is especially likely โ and especially worth addressing โ if your system is old, poorly maintained, or low on refrigerant. If your AC is constantly running or short cycling, it may be time to repair or replace it rather than keep patching the same issue.
My AC Runs, But It Smells Funky
AC units can put off a surprising range of smells, from the self-explanatory (mildew, cigarette smoke) to the baffling (dirty socks, engine exhaust) to the genuinely dangerous (natural gas).
- Mildew or musty smells usually point to moisture buildup in the ducts and often call for duct cleaning.
- Exhaust or burning smells tend to stem from a mechanical problem and are worth having looked at quickly.
- Natural gas smells near your outdoor unit aren't common, but if there's a gas leak nearby, that smell can get pulled into your home through the system. If this happens, get out of the house and call for help immediately โ don't wait to investigate.
Frequently Asked Questions
Why is my AC not cooling my house? Usually one of a few things: the thermostat isn't set to cool, a breaker has tripped, a filter is clogged, or the system is low on refrigerant. Work through the checks above first, and if the problem persists, it's worth having a technician diagnose the actual cause.
Why does my AC keep turning on and off? Short cycling like this is often tied to a system that's undersized, low on refrigerant, or simply aging โ and it's a sign your AC may need repair or replacement rather than a quick reset.
Why does my air conditioner smell bad when it runs? Musty or mildew smells usually mean moisture has built up in your ductwork; burning or exhaust smells usually point to a mechanical issue. A natural gas smell is the one exception that calls for leaving the house immediately rather than troubleshooting further.
