Why Is a Faulty Compressor Motor a Problem?

Friday, June 6th, 2014

The 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.

Ducted vs. Ductless Air Conditioning: Which Is Right for Me?

Friday, May 30th, 2014

When it comes to modern forced-air air conditioning systems, you have two distinct choices in front of you. First, there’s the standard central air AC that uses a network of ducts hooked up to a single indoor unit to distribute cooled air. Second, there is the ductless mini split heat pump, which has a similar outdoor cabinet to the central AC, but connects to multiple indoor units, called blowers, that are mounted in different rooms of a house. These blowers send conditioned air directly into the rooms, bypassing the need for ductwork or any sort of ventilation system entirely.

You have the choice. Which one will you pick?

If it seems like a hard choice, don’t worry.

Our technicians at Carney Plumbing Heating & Cooling are ready to assist you with deciding on the right system, whether it’s ducted or ductless air conditioning in Conshohocken, PA.

But to get you started, here are a few of the basic pros of the two.

Ducted (standard central air conditioning) advantages

  • Ideal if you already have ductwork in your home. A new system will easily hook up the the ventilation system with minimal installation work.
  • The cost less to install than ductless systems and take significantly less time.
  • They are easy to centrally control as well as service.

Ductless mini split heat pump advantages

  • A fine choice if you are planning new construction, such as remodeling, adding on a room to your current house, or building a new house entirely. You won’t have worry about duct placement or planning construction around ductwork.
  • Excellent for older homes that lack ductwork. You can retire those inefficient window units and have centrally-controlled powerful air conditioning.
  • Lack of ducts means no air contamination from dust or dirt gathering inside them, plus no loss of cooling through the duct walls.
  • The separate blowers allow for zone control, so you can adjust the temperature in different rooms without changing the temperature in all of the rooms at the same time.
  • All ductless mini splits are heat pumps, so you’ll have heating as well as cooling.

It may look like the “pros” of the ductless system easily outnumber those of the ducted system. But some of those “pros” for central AC are persuasive—especially if your home simply isn’t set up for a ductless system to work well with it.

If your still debating about whether to go ductless or not, call Carney Plumbing Heating & Cooling. One of our experts in ductless air conditioning in Conshohocken, PA will set up an appointment with you to look over your options when it comes to an AC for this summer. You can trust to our experience and integrity when it comes to home comfort.

How Geothermal Systems Can Both Cool and Heat Your Home

Friday, May 23rd, 2014

Geothermal systems form an alternative to traditional heating and air conditioning systems, and you often see geothermal cooling in King of Prussia and other nearby towns. The term can be a little confusing, since geothermal cooling systems can often be used to heat your home in the winter as well as cool it in the summer. How does that work? The equation can be confusing for those accustomed to separate units for heating and air conditioning. In truth, the principles underlying the system explains how geothermal systems can both heat and cool your home.

How Geothermal Works Both Ways

The temperature beneath the earth doesn’t change. Once you get past the first five or six feet, the changes in temperature above ground don’t affect it at all. That constant allows a geothermal system to facilitate a heat exchange through the coils buried under the earth. The coils carry a mixture of water and antifreeze which allows the heat exchange to take place. In the summer time, the mixture pulls heat from the air in your house. Then the system pumps it through the coils, where the heat can bleed out into the surrounding earth. In the wintertime, the process is reverse. This time, the cool mixture pulls heat from the earth, then carries it back into your home, where it can be released into the air with a fan. The relationship is basically the same, the only question is which direction the heat is travelling.

That versatility is a big part of the geothermal system’s appeal. It allows you to both cool and heat your home with efficiency and ease. Geothermal systems use very little energy, which means they can save you a great deal on monthly costs. Best of all you can use geothermal cooling in King of Prussia during our hot summers without having to worry about switching systems when temperatures get cool this fall.

The experts at Carney Plumbing, Heating & Cooling can help you plan and install a solid geothermal cooling system on your property. Give us a call to set up a consultation today!

The Advantages of Ductless Mini Split Air Conditioning

Friday, May 2nd, 2014

The hot weather is almost here. For some, the heat is just what they’ve been waiting for, but for others, it can be downright uncomfortable. Air conditioning is great for cooling off and keeping your body temperature regulated during the summer months, but if your property doesn’t have a duct-based heating/cooling system, your air conditioning choices have been limited – until now. Consider a ductless air conditioning installation in Bucks and/or Montgomery County.

The Ductless Air Conditioner

Your first thought may be that a ductless air conditioner equals a window air conditioner. You wouldn’t be wrong, but we’re talking about something much better: a ductless mini split.

A ductless air conditioner, also known as a ductless mini-split air conditioner, is a unit that allows for controlled air conditioning in your property without having to install a fully-ducted air conditioning system.

There are two components to a ductless air conditioner: the indoor unit, which blows and controls the cool air, and the outdoor unit, which contains the compressor/condenser. The outdoor unit can power up to 4 indoor blowers.

Indoor units can be placed on a wall or ceiling inside a room, and a conduit between the indoor and outdoor units holds the refrigerant tubing, suction tubing and condensate drain, and links the two units together.

Why Choose a Ductless Air Conditioner?

Ductless air conditioners are a great choice for properties that have non-ductless heat, such as older homes or multi-unit properties, where installing ducts is costly. They are also excellent for spaces that require retro-fitting.

Installation of a ductless air conditioner is much simpler as compared with a ducted system. First, the conduit length that runs between the components can be quite long – up to 50 feet apart – allowing for the indoor unit(s) to be installed in front rooms while the outdoor compressor resides in the back of the property. There is no messy ductwork to contend with, just the simple install and connection of the two components.

Second, the placement of the indoor unit(s) is/are also very flexible. The indoor component can be installed flush against a wall or ceiling, or suspended from a ceiling, including drop ceilings. There are also floor-standing models if needed.

Third, a single outdoor compressor can handle up to 4 indoor air blowers, and each blower can be programmed to maintain a consistent air temperature, boosting efficiency and saving you money.

Lastly, ductless air conditioners are safer than window units, as they do not provide a potential entrance to your property.

Stay Cool Without the Ductwork

A ductless air conditioner may be just what your property needs to stay cool and comfortable during the warm weather months. Interested in find out more?

Ways to Avoid Paying Too Much for Air Conditioning This Summer

Friday, April 18th, 2014

Spring is here and that means summer can’t be too far behind. In Lansdale, air conditioning systems are an absolute godsend in keeping high temperatures at bay. But because you will probably use your air conditioner every day, monthly bills are apt to be higher than normal too. That’s to be expected of course, though the high temperatures might hide some unnecessary waste in the bill. You’re already paying a lot, so you shouldn’t have to pay any more than is absolutely necessary.  Here are some ways to avoid paying too much for air conditioning this summer.

  • Schedule a maintenance session. Air conditioning systems build up dust and debris over time, which can increase friction and wear and tear on moving parts. Loose fittings, low refrigerant levels and unclean filters can also interfere with your air conditioner’s ability to do its job. A maintenance session can address all of that, improving efficiency and helping your unit perform at its very best.
  • Consider a cost-saving upgrade. Smart thermostats and zone control systems can help you cut down on monthly costs considerably, the first by analyzing your cooling habits and helping you make the most of them and the second by allowing you to turn off the cool air in parts of the house you aren’t using. Over time, the savings could very well pay for the cost of the upgrade.
  • Add insulation. Most people think of insulation as something that keeps the heat in, but the same principle works for keeping heat out as well. If you can, add more to your home before summer hits. You’ll be surprised how much you can save.

This comes on top of more straightforward ways to avoid paying too much for air conditioning this summer, such as dressing in light clothes and setting the thermostat for a few degrees warmer than you otherwise might. Here in Lansdale, air conditioning maintenance and upgrades can be performed by the experts at Carney Plumbing, Heating & Cooling. Give us a call to make an appointment and let us show you what we can do!

Why You Need Regular AC Maintenance

Friday, April 11th, 2014

Here’s something you should have on your spring “to do” list: “Schedule regular air conditioning maintenance.” An annual inspection and tune-up for your air conditioner is vital for it effective and efficient operation, and the best time to have it done is during the spring. That way, the AC is prepared for the upcoming change to summer, and you can take advantage of the slower time of the year for HVAC technicians to schedule a convenient time for uour maintenance visit.

In Blue Bell, PA, air conditioning maintenance from Carney Plumbing Heating & Cooling will make sure your AC is ready for summer, and that you receive the maximum value from the system. Our air conditioning technicians are all EPA-certified and have the necessary skills to make sure your cooling system is operating at maximum efficiency.

Why Regular AC Maintenance Is a Necessity

  • Catch potential repair needs: A key part of maintenance is prevention. Many faults inside an AC will not make themselves immediately obvious to you, but maintenance technicians know how to spot them. The technician will discover places where wear and tear in the system is developing into a problem and notify you of it so you’ll have time to fix it before it becomes worse—or before it causes the system to break down entirely and require more expensive repairs.
  • Increase system efficiency: As an air conditioner runs over a season, it will pick up dust and dirt. This will cause the AC to gradually run less and less efficiently, since it will strain to keep your home cool. This will mean higher bills. Here’s something to keep in mind: the average AC system in Bucks and Montgomery County runs for approximately 2,000 hours a year… more than enough time to build up plenty of dust and dirt contamination and deterioration on parts. Unless you have the system regularly tuned-up and adjustments and cleaning done, you can expect a continual decline in energy efficiency.
  • Ensure long system lifespan: Any air conditioning system comes with a manufacturer’s estimated lifespan, which is often in the 12–15 year range. However, this lifespan is only possible if the system receives regular maintenance. If you neglect routine visits to tune-up the system, all those 2,000 hours of work each year will shorten the AC’s lifespan. This is the biggest expense you can encounter with a cooling system: needing to prematurely replace it with a new one.

Air Conditioning Guide: Signs of an Overloaded Compressor

Monday, September 9th, 2013

You may have heard mention of the “compressor” in your air conditioning, but what does it actually do? In simple terms, the compressor is the “engine” of your AC. It compresses the refrigerant that comes from the indoor evaporator coils before it travels to the condenser coils, making the refrigerant both hot and highly pressurized. This is an essential part of the cooling cycle.

If your compressor overloads, it can cause serious trouble for your system. In this post, we’ll run through a few of the signs that your compressor is working too hard and possibly heading for a burn out. For Lansdale, PA air conditioning service, trust Carney Plumbing Heating & Cooling for expert knowledge:

  • Noisy operation: You turn on your AC, and instead of the whir of soothing white noise you expect, you hear a strange buzzing or clanking sound. Although a number of components in your unit can cause unusual sounds if they aren’t working properly, these specific sounds often point to the compressor.
  • Increased electrical bills: You probably know what to expect on your energy bills during a season—so if you notice an unexplained uptick in what you’re paying for electricity during the month, it may mean that the compressor is draining too much power to do its job. The compressor requires the most energy of any part in your AC to run. Getting the compressor repaired can not only prevent failure, but also save you money.
  • Circuit breaks and blown fuses: A compressor that is working too hard can cause a power surge that may trip a circuit breaker. This will happen soon after the compressor starts operating, so if you experience trouble with circuit breaker or blown fuses not long after you switch on your AC, the compressor is the likely culprit.

It is a smart idea to call in an HVAC technician to deal with an overworked compressor. Trying do-it-yourself tactics can not only damage your AC, but pose the danger of electrical shock. A professional can safely perform the diagnosis and help determine if your compressor needs repairs or replacement. When you need this work done, call Carney Plumbing Heating & Cooling’s Lansdale air conditioning experts—we’ll give you the service satisfaction you need to keep you cool.

What is an Expansion Valve?

Wednesday, August 21st, 2013

When discussing air conditioning systems, you may her the term “expansion valve” used from time to time. It plays a vital role in the process of cooling your air, but you may not be familiar with its particular function. In New Hope, PA, air conditioning systems are a serious concern, since Pennsylvania summers can be hard with all the heat and humidity. The more you understand about components like the expansion valve, the better your grasp on how air conditioning works.

At the heart of your air conditioning system is a closed loop system that circulates refrigerant. The expansion valve plays a key role in this loop. The refrigerant arrives at the value in a highly pressurized liquid state. The valve is connected to the system’s evaporator coils. When the refrigerant enters the coils, it evaporates, absorbing heat out of the nearby air in the process. A blower then pushes the cool air into the ductwork, where it travels throughout your home.

The valve regulates the amount of refrigerant that is let into the evaporator coils. As the liquid moves from a high pressure state to a low pressure state, it evaporates and absorbs the heat from the surrounding air. Only a precise amount of refrigerant will work properly, so the valve’s purpose is extremely important. And naturally, when the valve become clogged or damaged, it can wreak havoc with the AC unit’s ability to cool the air. If refrigerant can’t enter the coils, no cooling will take place. If it enters in the wrong proportions, it will cause problems with the pressure leading to too much or too little cooling, and possibly damage other components as well.

Repairing or replacing an expansion valve is the purveyance of trained professionals. They can ascertain the problem, effect a repair, or replace it with a new valve while ensuring that it fits in with the surrounding components the way it should. Carney Plumbing Heating & Cooling can address problems air conditioning units in New Hope, PA and throughout eastern Pennsylvania. Call us today to set up an appointment.

Does Air Conditioning Reduce Indoor Air Quality?

Monday, August 12th, 2013

The hot, muggy summers in Lansdale, PA make air conditioners an absolute necessity. What better way to avoid climbing temperatures than with a cool comfortable living space to come home to at the end of each day? Some homeowners may have concerns about their indoor air quality as well, and wonder if an air conditioning system will reduce the quality of their indoor air. The answer depends on how regularly the air conditioning unit is maintained.

Dust and dirt particles are a fact of life, and may build up in your air conditioning system over time.  The amount will increase if you have pets that carry dander, if your indoor carpeting goes a while between cleanings, and if you track in a lot of dust and dirt from the outside. To counteract this, air conditioning units come equipped with air filters which catch dust and other particles, preventing them from building up in the system itself.

Here’s where proper maintenance enters into the equation. If you change your air filters regularly, they won’t become clogged with particles, and the quality of your indoor air should remain high. In addition, a higher quality filter tends to do the job better than a cheap or flimsy filter. Similarly, regularly scheduled maintenance from a trained professional can keep your AC unit clean and free of dust. You can augment that with routine ductwork cleaning to keep debris from building up in your ducts. In both cases, an expert can also spot potential problems, such as cracks of fissures that may allow particles to enter the system, before they become overwhelming.

If, on the other hand, your air conditioning system doesn’t receive any significant upkeep, then the amount of dust in the system will probably lower your indoor air quality.  If you’re concerned about the quality of your air – especially if you have allergies or similar issues – the give Carney Plumbing Heating & Cooling a call. We can set up a regular maintenance schedule, and handle air conditioning issues in Lansdale, PA and throughout the surrounding communities. With regular service, we can help ensure that your indoor air quality stays where it should be.

Air Conditioning Repair: What AC Noises May Mean

Monday, July 15th, 2013

Does your AC make a strange or unexpectedly loud noise during operation? Has it gotten louder over the years and is now unbearable during operation? While you can expect a certain amount of noise from your air conditioner, if it begins to make any strange sounds, you should get in touch with your HVAC technician. In some sense, you should see that sound as an advantage—many problems around the home do not let themselves be known until they are too far gone. If you view that noise as a warning signal that your AC needs the care of a professional air conditioning repair technician in Doylestown, PA.

Let’s take a look at a few sounds that you may come across during the service life of your AC:

  • Grinding: This is often a fairly grating sound, one that is immediately recognizable as an indication of damage. A grinding sound in your AC is probably related to dried-out bearings in your blower motor assembly. When dirt, dust, and grime enter into your motor, they can cause friction and overheating. If you think this is what’s going on, make sure you turn your AC off to prevent any further damage.
  • Buzzing; If you hear a buzzing sound around your AC, you might have a serious electrical problem. It might indicate an arcing issue, which can be hazardous to you and the integrity of your AC if not taken care of properly.
  • Loud banging: If it sounds like two pieces of metal are striking against one another in your AC, then that’s probably what’s going on. You may have a fan blade that has come loose or some other loose part that is being blown around your system.

It’s necessary to have a professional diagnose the sound that your AC is making so that you can be sure that the root of the problem is taken care of. Call Carney Plumbing Heating & Cooling today for all of your Doylestown, PA air conditioning repair needs. We can make sure that your cooling system gets the attention it deserves.
