The system turns on and off frequently.

Your energy bills are climbing, but your air conditioner usage hasn’t increased.

Dust and pollen can be found inside.

Some areas of your home or office are comfortable, while others are noticeably warmer.

Down to the Wire Faulty or damaged wiring is no joke

Faulty wiring in AC units can lead to the circuit breaker tripping, fuses being blown, and/or the AC system shutting down.  You can check for frayed or damaged wiring yourself in any visible areas.  If found, call a professional for AC repair immediately as any damage of this kind can lead to a fire, and wiring is certainly not a DIY matter.  Of course, faulty wiring may not be readily visible.  If your AC unit is functioning intermittently or your thermostat seems to be ineffective, calling a professional to look into the wiring would be a prudent decision.  If your thermostat is old, you may consider replacing it first, just in case that is the issue.  If the thermostat is not the issue, call U.S. Air Conditioning and Heating to let our experienced HVAC contractors diagnose the problem and provide AC repair on-site usually within a single visit.  Our professionals arrive in a fully-equipped van ready to tackle most problems, including wiring, without delay.  Faulty wiring is a dangerous fire-hazard that can’t be allowed to exist in a home, and our experienced professionals consistently perform quality work that will ensure your family’s safety.

Frozen coils are nothing to sing about and you can’t just let it go What could be causing the coils to freeze

Cold coils are ordinarily kept from freezing by the warm air traveling from your home through the intake and over the coils.  This air is cooled as the coils absorb the warmth and condense any moisture in the air.  The condensed moisture collects in the pan and drains out of the house.  Without the warm air coming in, the coils freeze before any condensed water can collect into the pan and drain.  Dirty filters and closed air registers can inhibit warm air flow, leading to frozen coils.  Frozen coils can also be caused by low refrigerant and a malfunctioning fan.  Faulty thermostats can also create this issue, as can an obstruction in the drain.  Running an air conditioner with frozen coils can lead to severe damage to the compressor.  If your AC is blowing out warm air, your coils may be frozen.  You can also visually check to see if this is the case.  Make sure your air filter isn’t dirty and inhibiting the air flow.  Your air filter should be changed once a month.  If your coils are frozen and your air filter isn’t at fault, call a professional HVAC contractor.  U.S. Air Conditioning and Heating technicians can diagnose the problem and fix it with minimal disturbance to your routine.  Highly-trained and experienced, our professionals conduct AC repair with fidelity, ensuring that the root of the problem is addressed and your AC is left in top operating condition.

Pull out the Stops When the condenser fan stops or malfunctions

The condenser fan is located in the outside portion of your AC unit and can easily be seen spinning while your AC is running.  When in proper working order, the fan should be spinning, the condenser lines should be cold, and the air blowing into your home should be cool.  If the fan isn’t spinning or warm air is blowing into your home, you have a problem.  If the fan won’t turn on at all, and you’ve checked that the thermostat was set to COOL and ON, then the AC unit could have an overheated or damaged fan motor. If the fan turns when the AC is off, but doesn’t rotate when the AC is on, the unit may have a bad motor bearing, resulting in an unbalanced fan rotation when the fan does manage to rotate. The fan should also be running at a decent speed. If you notice the fan running slower than normal, the control board or circuits may have issues causing low voltage to the unit.  The fan blade itself may also simply be loose from the motor shaft or the capacitor could be causing a slow fan rotation.  Wiring issues, circuit board problems, or loose components can cause the fan to start and stop in the middle of cycles or cause the fan to run constantly even when the AC is off. Any of these issues should be investigated by a reliable HVAC contractor so the problem can be addressed before damage spreads.  The fan’s purpose is to transfer heat out of the compressor, and if it malfunctions, the compressor could overheat and be internally damaged.  Noises such as buzzing, ticking, or rattling in the fan should also not be ignored or discounted.  An obstruction could be hitting the blade, the motor or blade bearings could be malfunctioning, or a blade could be bent.  Nearly all of these problems can be visually confirmed, but the fix almost always requires a professional HVAC technician.  For any fan issues, our HVAC professionals at U.S. Air Conditioning and Heating are more than qualified to diagnose and address any problem your AC unit may be having.  AC repair conducted by our nationally certified technicians is always done with quality and precision in a timely and efficient manner.  Call today and let our certified technicians return your AC unit to optimal working status and restore your peace of mind.

Too Much of a Good Thing is Bad The dangers of overcharged refrigerant

Usually the result of air conditioning service conducted by an inexperienced repairman, too much refrigerant in an AC Unit can damage the compressor.  The excess refrigerant needs a place to go and will end up collecting inside the compressor.  This leads to subcooling, temperatures below normal; slugging, damage caused to mechanical components as a result of the compressor flooding; and high pressure in the system, making it more expensive to run because the cooling process isn’t working effectively.  Fixing a damaged compressor, when possible, is extremely expensive and when not possible, requires the entire system to be replaced.  If your home isn’t cooling effectively, yet your electric bill has risen, then overcharging may be the problem with your AC unit.  An HVAC professional from U.S. Air Conditioning and Heating is well-qualified to drain any excess refrigerant and repair any damage that it may have caused.  All of this can be accomplished in one visit because each of our highly-trained HVAC contractors arrives in a fully-equipped van, prepared to diagnose and fix most problems your AC unit may be having on-site and without delay.

Less is not More The dangers of undercharged refrigerant

Much more common than an overcharged unit, undercharged AC units are often the result of a leak.  If your AC unit is undercharged, you will notice the loss of cooling performance in the home and, if you investigate the problem more fully, ice forming on the evaporator coils.  Ice forms because there is no longer a sufficient amount of refrigerant in the coils to absorb heat for the coils to warm up.  This problem can be easily handled by the HVAC contractors at U.S. Air Conditioning and Heating.  Getting your AC unit’s refrigerant to be at just the right charge is a delicate process that needs to be handled by professionals who won’t accidentally overcharge your AC unit, causing often permanent damage to your compressor if not addressed quickly.  U.S. Air Conditioning and Heating employs certified professionals averaging 15 years of experience or more.  We know the importance of providing quality air conditioning service and you can rest assured that a job completed by us is a job done well.

Low-Maintenance vs. No Maintenance What routine maintenance can do for you

Regardless of the age of your AC unit, regular maintenance will help prevent those large repair bills everyone fears.  Your unit’s refrigerant should remain charged at the optimum level.  Finding a leak before it leads to other problems could save you on future repair costs.  Small noises from the fan that often go unnoticed or ignored can be early-warning indicators of a part going bad, an alignment that’s off, or an obstruction doing damage.  U.S. Air Conditioning and Heating recognizes the value in preventative maintenance and offers an agreement to clients that includes two annual visits, precision tune-ups, emergency service, discounts on parts and repairs, and more.  To take advantage of the low-cost Preventative Maintenance Agreement, call today to get the full details.
