Are you a bit hot under the collar? If you had a power outage during one of Arizona’s monstrous monsoons, the central AC may not have come back on. So what do you do? Follow these 5 steps to restart your AC safely and get your comfort back. Go to your thermostat and set it to “off.”  This will stop your thermostat from calling your AC for cooling so you can reset the circuit breaker. Most likely, a power surge from the storm overloaded the AC’s circuit, causing the circuit breaker to “trip.”  So you’ll need to reset it. The circuit breaker box (a grey metalic box) is usually located in these areas: Open the circuit breaker box and find the circuit that has an air conditioner/HVAC label next to it. It’s OK if there’s no label. Just look for a switch that is “tripped,” meaning that’s it’s moved to the neutral position. To reset the circuit breaker,  turn it to the “off” position (right), then the “on” position (left)

Your AC needs some time to reset its internal circuit breaker. Drink a cold drink. Take a swim (probably not during the monsoon, though). Do whatever you need to do to stay cool. Head back to your thermostat, set it to cool and make sure the temperature setting is at least 5 degrees below the room temperature. The thermostat should call for cooling from the AC. Now celebrate, because you just got your comfort back!My circuit breaker tripped again!” If the breaker trips soon after you reset it, you have another issue you need to deal with first before attempting to reset the circuit breaker again. Read more in our article: “Why is My Air Conditioner Tripping the Circuit Breaker?” If you followed our instructions and the AC is still not working, there may be an electrical issue with the AC.

Until, that is, they start leaking, heating imperfectly, burning toast they were supposed to brown, and generally malfunctioning. Although they may seem complicated, most home appliances work on fairly basic principles. And while there is a common sentiment these days that it's less expensive to simply buy a new appliance than to have it repaired, many of the minor problems that plague these devices can be dealt with using a minimum of time and effort. So the next time an appliance is on the fritz, consider the local landfill, and then decide whether to fix it or ditch it.There's water pooling around your central air-conditioning unit (or perhaps dripping from the ceiling directly below the unit location).According to Glenn C. Hourahan, vice president of research and technology for Air Conditioning Contractors of America, it's likely that the drain pan for the air-conditioning evaporator coil is overflowing due to a blockage in the drain line. "Depending on the type of unit you have, the evaporator may drain to the outside of the house or to a floor drain in the basement.

Either way, use a long wire (an unwound coat hanger will work) to clear any blockages that may occur near the mouth of the drainpipe. If that doesn't correct the problem, cautiously (you don't want to introduce much additional water into an already flooded pan) use a hose to force a short blast of water up into the drainpipe and through the drain trap and drain pan. This may free accumulated dirt and allow the evaporator to drain freely for some time." If that doesn't do the trick, Hourahan recommends turning off the air conditioner to avoid further water overspill and calling a licensed HVAC contractor to have a NATE-certified service technician address the situation.portable air handling unitSigns of Central Air-conditioning CrisisCentral air-conditioning systems are fairly complex but, fortunately, fairly reliable. prices of carrier ac units

Beyond the simple power outage or clogged condensate drain line, more serious problems are best left to experienced, licensed technicians. Signs that should lead you to call for service include:+ Unit running but no cool air coming out. If the appliance cools intermittently, it usually points to a problem with the refrigerant and may mean the system needs to be recharged.+ Odd sounds coming from the condenser/ compressor unit. Turn off the unit and call for service.+ The system doesn't come on at all. tax credits for new ac units 2012First check the obvious culprits--that the thermostat is set to cool and that the appliance's circuit breaker is in the "On" position. Likewise, check all other system switches or disconnects. If these aren't the problem, make sure the air-conditioner is off and call for help.+ Any significant leak or a dripping circuit breaker. This should be dealt with immediately by a professional.

Turn off the unit and make the call.The mercury is plummeting and you're trying to find all those extra sweaters because your oil furnace isn't coming on.Every oil-burner unit has a reset button that will trip from time to time. It's a red button on the box at the burner. Press it and the burner should fire right up, making your house a warm home again. However, do not try the reset button more than once.Some conditions are signs of bigger problems than most people can handle at home and require the help of a heating pro. According to John Levey, owner of Oilheat Associates in Long Island, New York, and the director of education for the Oil Heat Institute of Long Island, these include:+ Chimney smoke. Oil burners typically give off smoke from the chimney and/or soot in the boiler room when combustion problems arise. These early warning signs indicate the need for professional attention and are often caused by minor problems that can be repaired quickly and inexpensively. If they are not promptly repaired they can lead to more serious trouble and more expensive repairs.+ Burner doesn't run.

Oil burners require electricity to operate, so the first things to check are the large wall-mounted shutoff switch and the circuit breaker or fuse. If the switch and breaker are in the "On" position and the burner still doesn't fire, press the reset button on the primary control once. Never press the reset more than once because doing so can cause serious problems. If the burner starts and continues to run after the reset button is pushed it's important to understand that it went into reset for a reason. Chances are that there's a minor problem that requires professional attention.+ The system doesn't come on at all. If these aren't the problem, make sure the air-conditioner is off and call for help.+ Cycling too frequently. Burners normally cycle on and off numerous times during the day, but if the unit is continually cycling it may be a sign that the controls are not properly adjusted or, on warm-air systems, that the filters have become clogged. Before calling a professional, check your air filters and, depending on the model, replace or clean them if they've become clogged.+ Odors.
