We often get this question from homeowners who want to make sure that their air conditioners are in ideal condition for the summer. While it is true that there are certain conditions under which your air conditioner would need more refrigerant, these are rare. Let’s take a look at how your air conditioner uses refrigerant, and when you need to have more added to it.

Do I Need to Put More Refrigerant in My AC?
Monday, July 25th, 2016Listen for These Air Conditioner Noises
Monday, April 25th, 2016Have you noticed any strange noises coming from your air conditioner since you started using it this summer? If so, you probably have a problem. Usually, the reason that an air conditioner starts making strange noises is because there’s a problem with the system. Let’s take a look at some of the more common problem noises that air conditioners make, and what they mean.
When to Call for Air Conditioning Repairs
Monday, March 28th, 2016Summer is not far off now, and the weather is already beginning to warm up. As the temperature rises, you’re probably going to start relying on your air conditioner more and more to keep your home cool. That added usage translates to more strain on the system, which means a higher chance for things to go wrong. Let’s take a look at some of the common air conditioning problems that you should look out for this season.
3 Common Types of Air Conditioning Repairs
Monday, May 11th, 2015There are many components and moving parts in your air conditioner, which leaves quite a bit of latitude for problems. However, there are some key areas that our technicians see problems with more often than other parts. This doesn’t mean these parts are faulty; rather, it indicates that these parts are sometimes put to more use than others, and as such, they can develop more wear and tear. No matter what your repair issue, though, it’s important to always call an expert for help, like the ones at Carney Plumbing Heating & Cooling. We’ve been helping customers in the Fort Washington, PA, area with air conditioning repair since 1976, and we bring this experience and expertise to every job we do. Call us today, and let our AC specialists get your air conditioner back on track.
Why Is a Faulty Compressor Motor a Problem?
Friday, June 6th, 2014The core of an air conditioning system is the compressor, which is located in the outdoor condenser cabinet. When an AC switches into cooling, the compressor makes a noticeable humming noise that you probably associate with all air conditioners: that’s the indication the process that creates the heat exchange cycle to remove warmth from your home has started. The compressor increases the pressure of refrigerant by decreasing its volume; the refrigerant changes into a hot, high pressure gas and starts on its path through the air conditioning system until it returns to the compressor.
A compressor resembles a motor in the way it operates, but it needs its own motor to run. Compressor motor faults are serious because they threaten to stop the heat exchange cycle. If you suspect a failing compressor motor, contact Carney Plumbing Heating & Cooling right away for air conditioning repair in Quakertown, PA. We offer same day service, your satisfaction guaranteed.
Why motor faults are bad news for the compressor
The compressor motor is similar to most motors: it can suffer from excess stress due to overwork, loss of lubrication, and dirty components. Other problems a motor can encounter include loose wires and a bad start relay. When the motor starts to suffer from extra strain, the air conditioner will begin to “hard start”—i.e. the compressor will struggle to turn on, and it may only work for a short period before it shuts off again. This puts stress on the compressor as well, and it drains large amounts of energy that will lead to an increase on your bills.
The biggest threat from a malfunctioning compressor motor is not that the motor will burn out and stop moving the compressor; that’s a serious issue that will require a technician change out the motor. The biggest danger is that the hard starting will cause the compressor to overheat and burn-out. A burn-out compressor can rarely be fixed. Replacing the compressor is costly, and often it means that the whole air conditioner must be replaced.
When you hear a grinding or screeching sound from the condenser cabinet, it probably means a motor is malfunctioning. Call for repairs immediately before the problem spreads to the compressor. Also call for technicians if the air conditioner begins to hard start.
If you act soon enough, skilled repair technicians can often fix the problem quickly and thoroughly so it will not start up again. However, in cases of aged ACs, sometimes a new installation is the best solution when the compressor and its motor have worn down too far.

Dirty Air Filters and Air Conditioning Repairs
Tuesday, June 11th, 2013Your air conditioning system has an air filter that is there to protect the moving parts on the inside from dirt, dust and other debris. If you don’t change that air filter on a regular basis it can cause problems with your AC. If your air conditioning system is having any issues, call the friendly experts at Carney Plumbing Heating & Cooling. We have many years of experience working with all different kinds of air conditioning systems. We wanted to put together some of the common issues that can be caused by allowing your air filter to get clogged.
- Not enough cooling – If your air conditioning system isn’t producing enough cooling a very common cause of that could be a clogged air filter. If your air filter is full of dust it will restrict the flow of air into your home and cause you to be uncomfortable.
- Increased repair – If you have a clogged air filter it will cause your air conditioning system to have to work harder to pull air through the system. This will put more strain on your equipment and could cause other AC problems to develop.
- Increased energy usage – If your air conditioning system has to work harder to pull air into the system then it will need to use a lot more energy.
- Reduced lifespan – When your air conditioning system has constantly run to cool your home because of a dirty filter, there will be more wear and tear on the system. This could cause parts of the equipment to prematurely wear out, and it could even cause the entire system to break down permanently.

Why is My Central Air Conditioner Making Noise?
Monday, July 9th, 2012A good air conditioner is a life saver in the midst of a hot and sticky summer, but just because the system makes you comfortable and makes the hottest months bearable doesn’t mean you want to hear it clanging and banging all summer. If you notice excess noise coming from your Newtown air conditioner, it might be a problem that can be fixed by your technician. Here are some common causes of excess noise from an air conditioner and what you can do to fix them.
- Blower – The blower is a motor and fan blade assembly. If the blade touches the housing or if the motor needs a tune up, it might start to make excess noise. Loose screws, foreign objects, or a need for oiling or new parts will all cause noise problems.
- Ductwork – If the sounds you’re hearing are in the ductwork or vents, it may be due to expansion and contraction in your ventilation system. This is normal and while it may be obnoxious, it tends not to persist during the hottest months as temperature won’t fluctuate as much.
- Bubbling Sounds – If you hear a gurgly or bubbly noise coming from your indoor unit, it may be due to a blockage in the condensate line. The easiest solution is to have a tech clean the condensate line and check for any clogs or blockages in the system.
- Clicking Sounds – If you hear a clicking sound, it is likely from the relay or contactor in the system. If this is the case, have a Newtown AC professional check it right away. Electrical problems are not to be taken lightly where your air conditioner is concerned.
- Foreign Objects – Sometimes, the condenser fan will make a lot of loud noise because foreign objects get stuck in there. Sticks, leaves, toys, food from small animals – it can all get stuck in the fans and make a tremendous amount of noise. Keep the area around your condenser unit clear of debris and check it often if you hear loud noises.
Most noises from your Newtown central air conditioning unit are explainable and can be fixed relatively easily. If you cannot find the source of the noise, however, and it is only getting worse, call Carney Plumbing, Heating & Cooling before the problem grows.
What Are Thermostatic Expansion Valves?
Monday, June 11th, 2012The thermostatic expansion valve, sometimes known as a TEX, TEV or TXV, is a critical piece to influence the efficiency of your Blue Bell air conditioning and refrigeration units. A tiny sensor controlling the evaporating phase of process, the valve can have a big effect.
Cool air is manufactured by a re rapid movement of a refrigerant between liquid and gaseous states. Compound chemicals that are able to do this at a low temperature are compressed and expanded, absorbing and releasing heat at different points along the way. The TEV controls the flow of the refrigerant into the evaporator coils according to the temperatures of the various ingredients.
Cool Air 101
To condition air, the refrigerant, most often freon or another fast acting, low temp compound, evaporates into a gas that runs through a coil and absorbs heat. Passing through a compressor, the freon condenses under pressure back into a liquid again and releases the heat, becoming cool enough to chill a party.
Too much freon in the evaporator tube and the pressure is not low enough to expand to gas and absorb heat, working inefficiently for no gain. Too little freon and the conversion is also ineffective by not reaching the density needed to condense.
There are four types of valves with different benefits for different types of cooling environments. With its ability to adjust minutely to changing conditions, the thermal expansion valve creates the perfect mixture of pressure and freon for more complicated systems.
At the Starting Gate
An interactive device, the valve senses the evaporator pressure and temperature and adjusts the flow of the refrigerant so as to maintain a given “superheat”, the difference between the refrigerant vapor temperature and its saturation temperature. By controlling superheat, the TEV keeps nearly the entire evaporator surface active while not permitting liquid refrigerant to return to the compressor.
Some valves operate on an electrical impulse from sensors that can measure the temperatures. Others are open all the time. The thermostatic expansion valve actually utilizes the pressure between the two sections to open or close itself, regulating flow based on the very same pressure it is designed to moderate.
Like the buildings they comfort, Blue Bell central air conditioning systems are varied and diverse. There are nearly as many thermostatic expansion valves as there are units to receive them. Call Carney Plumbing, Heating & Cooling today if you need any air conditioning service in the Blue Bell area!
Steps to Take When Your HVAC System Breaks Down in Jamison
Friday, September 9th, 2011Imagine this – it’s a sweltering summer day in Jamison. The humidity outside is obscene, hitting you like a wall when you open the door. So, the only place you want to be is on the couch with the cool air conditioned air being blown across your face. Sounds pretty good doesn’t it? Now, imagine what happens when that cool conditioned air stops flowing.
A breakdown in your HVAC system is the absolute last thing you want to experience on a day where the mercury dings 90+ but it can happen, and the only way to ensure things don’t get out of hand is to take the following steps.
- Check Common Problems –While the system itself could be broken, make sure there are no other issues involved. Frequently, the electricity supply can be interrupted by a power surge or a tripped breaker. In both cases, you can usually get the system back online by yourself. However, you should call an electrician to inspect it as soon as possible.
- Does it Turn On – If the air conditioning system turns on and simply doesn’t provide enough cooling for your home, it is likely a problem in the unit. In this case, check other common problems. Clogged filters can severely reduce efficiency and if the system freezes over, it may stop providing enough cooling.
- Still Not Working? – If the system refuses to turn on and there are not clear problems that you can fix yourself, it’s time to call a professional. A professional HVAC contractor should be available almost any day of the week for emergency calls like this. Of course, in the middle of a heat wave or cold snap, it’s very likely that they may be booked up for a couple days. To avoid this happening, have routine maintenance done as often as recommended to avoid the possibility of being without cooling or heating indefinitely.
A good HVAC system is the only thing standing between you and discomfort, or worse, danger to your health. Don’t let the system go into such disrepair that you can’t use it at all.
Warning Signs: When to Call for an Air Conditioning Service
Monday, August 8th, 2011The last thing you want is to be without an air conditioner during the hottest days of the year, especially in Elkins Park. Ideally you would never have to call for service to repair your air conditioning system, but just like anything else, your air conditioner will break down once in a while. However, you can dramatically reduce the inconvenience and cost of emergency air conditioning repairs if you are able to spot the warning signs of a problem before it shuts down your system completely.
For instance, all air conditioners make noise, but if your air conditioning system is suddenly making much more noise than it used to, chances are that something in there is not working properly. Calling for repairs when you notice this sudden increase in noise from your system will greatly increase the chances that the repair will be relatively minor and that you will not have to go without air conditioning when you need it most.
Also, it is a good idea to call for service if your air conditioning system does not seem to be doing as good a job as it used to when it comes to cooling your home evenly and effectively. Uneven cooling is a good sign that something is not working right within your system. And even if your air conditioner continues to work, it will probably be using up more energy than necessary for a less than ideal end result.
Along these same lines, a noticeable increase in humidity in all or part of your home is another good indication that something is wrong with your air conditioning system. Air conditioners both cool and dehumidify the air, so if yours stops removing humidity properly, you need to find out why.
In fact, even if you do not notice any difference in the way that your air conditioner is performing, you can still spot a problem if you keep a close eye on your energy bill. If you see a sudden increase in the amount of your bill because of the amount of energy that your air conditioning system is using, it is a good sign that something is not working right.
It may be tempting to put off calling for repairs, particularly if your air conditioner is still able to keep your house comfortable. However, it will likely be much cheaper and more convenient to have the repairs done early rather than waiting until the unit breaks down entirely.
