The East Coast Prepares for Frankenstorm!

Friday, October 26th, 2012

As Hurricane Sandy moves towards New England and a winter storm moves in from the West, the east coast needs to prepare for the potential effects of this massive storm.

Hurricane Sandy | Bucks County | Carney Plumbing, Heating & CoolingCNN Reports, “that Sandy could be a storm ‘of historic proportion’…There is a 90% chance it will hit the American Northeast, said CNN meteorologist Pedram Javaheri, where $1 billion in damage could mount as it rolls inland, even affecting parts of the Midwest.”

Here at Carney Plumbing, Heating & Cooling we have already been getting calls about sump pumps and sump pump back-ups from customers eager to prepare for the storm. If current weather predictions are accurate, Hurricane Sandy could be the greatest storm of our time.  With only days left before the storm hits in Bucks and Montgomery Counties now is the time to prepare.  Here are some helpful tips to keep your family safe during the storm:

Before the storm hits:

  • Build an emergency kit, including food, water, warm clothing and other supplies.  Plan ahead for the specific dietary or medical needs of your family.  Pack enough supplies to last at least 72 hours.  Include any items that will help you stay warm and safe in the event of a power outage.  Please view these additional tips that may be helpful when preparing your emergency kit: http://www.ready.gov/sites/default/files/documents/files/checklist_1.pdf.
  • Bring pets indoors.
  • Plan an evacuation route taking elevation, existing bodies of water and flood-prone areas into consideration.
  • Take steps to secure your home, including covering windows, trimming trees and shrubs, clearing clogged rain gutters, reinforcing garage doors and bringing outdoor furniture and decorations inside.  Installing a generator is also a great idea for emergencies.
  • Turn your refrigerator to the coldest setting to keep items fresh in the event of a power outage.

 

During the storm:

  • Stay indoors and away from windows and glass.
  • Close interior doors.  Keep curtains and blinds closed.
  • Remain on the lowest level of your home in a small room, closet or hallway or lie under a table on the floor.
  • Avoid travel unless absolutely necessary.  If you need to travel, use main roads and only travel during the day.  Let someone know when you’re leaving, where you’re headed, what route you will take and what time you plan to arrive at your destination.
  • Listen to the radio or TV for storm updates.

 

We hope your family stays safe and warm this winter!

Why Cover Your Air Conditioner During the Winter?

Monday, October 22nd, 2012

Many air conditioner owners in Maple Glen wonder how best to care for their outdoor condenser units during the winter months that they are not in use. It can be a bit confusing, as everyone seems to have different opinions. Some people claim that wrapping your air conditioner is of utmost importance, while others claim that it can actually harm your air conditioning system. Ultimately the importance comes down to location of your home and the conditions of the environment, but at Carney Plumbing, Heating & Cooling we believe offering some sort of protection over your condenser unit is a good idea. The important thing is how you do it.

If you’re  concerned about debris falling into your unit, such as pine needles, ice or leaves, simply cover your condenser unit with a piece of plywood. Put a brick on top to hold it in place, and you’re all set. This will also keep rain and snow out, as well as corrosive salt water for those that live near the ocean. If you want to further protect your unit you may opt for a full cover, but it is important that you give this some further consideration.

If your concerned about the fins or casing of your condenser unit and must use a full cover, be sure that it is made of a breathable material. Sure, you may have some large trash bags in the garage that would cover it, but this can actually do more harm than good. Using plastic or other non-breathable materials to cover your air conditioner can trap moisture inside the unit. When the sun is shining during the winter the cover will heat up, making it much warmer inside the plastic and creating the perfect environment for rust and mildew to develop. Plus, this warm area makes a tempting place for rodents to spend the winter. Many electricians spend some time in the spring rewiring systems that have had their wiring chewed through.

Before you take any steps in protecting your air conditioner – consult your owner’s manual or as your Maple Glen heating and air conditioning contractor.  Most importantly, protect your air conditioner following the passing of winter in the most reliable way possible. Call a professional air conditioning service provider for regular maintenance service before putting your air conditioner into regular use. This is the best way to make sure that your AC has made it through the winter unscathed by debris, moisture, rodents and anything else. Call Carney Plumbing, Heating & Cooling  today with any further questions you may have about keeping your air conditioner safe during the off season.

Why Should I Be Concerned about the Refrigerant in My Old AC System?

Monday, September 10th, 2012

All old ACs used R-22 refrigerant to carry out cooling functions. In fact, R-22 has been the choice for global AC systems for decades now. But did you know that this refrigerant can be a real danger for the environment? R-22 is one of the more harmful greenhouse gasses and it can cause serious damage to the Ozone layer.

In fact, R-22 has been banned in most places and is going to be phased out by the year 2020. Most manufacturers have stopped using this refrigerant and it is going to be increasingly difficult to find on the market. R-22 is also going to become more expensive in the near future. In fact, the trend has already caught on in most parts of the world.

Considering the amount of damage R-22 causes to the environment, you don’t really need more of a reason to consider changing refrigerant from your Ambler home’s old air conditioner. The best and most recent answer to this issue is the use of another refrigerant known as R-410A. This refrigerant is being marketed under different names by various manufacturing companies but it is essentially the same thing. Though you will still find R-22 refrigerant till the year 2020, it is still a smarter option to make the switchover as early as possible. If you can do your part towards helping the environment, why not do so at the earliest time possible?

For more information about your Ambler air conditioning system, give Carney Plumbing, Heating & Cooling a call today!

Why is it Important to Keep Your AC Condenser Coils Clean?

Monday, August 27th, 2012

Condenser coils perform an essential function of conditioning hot, moist air and replacing it with cool, dry air.  During this process the continual circulation of air causes airborne pollutants such as dirt, dust, grass, lint, moisture and other debris to land on the coils, building up until it gets clogged.  A clogged or dirty AC condenser coil is most definitely a problem.

The main problem with dirty coils is that it decreases how well the AC actually cools.  A clogged coil can mean deceased air flow through the coils, which in turn means your Doylestown air conditioning system will be less efficient.

Clean condenser coils can yield higher performance levels, cleaner indoor air, and a longer life expectancy of the unit, while also saving money in electricity costs. Performance levels of air conditioners with dirty coils drop by as much as 30%!

When air passes over a dirty condenser coil and is then pushed into indoor air after being cooled it only stands to reason that some of that dirt and debris gets taken indoors as well.  It can also cause moisture problems on the coils which could result in bacteria or mold spores growing, and might reduce indoor air quality in your home.

Dirty coils can also cause the AC to work at higher temperatures and higher pressure which means the lubricant cannot easily be broken down. This can make the unit freeze over, eventually causing compressor failure.

Carney Plumbing, Heating & Cooling can help clean your condenser coil during a regular AC maintenance checkup – give us a call today if you need AC service!

Benefits of Forced Air Systems

Monday, August 13th, 2012

Forced air systems are usually hooked up to both a heating element and an air conditioning element, both of which send their pre-treated air through a series of ventilation ducts located throughout a building.  Many times the heating and air conditioning devices are separate, such as a gas furnace for heating and a central air conditioning unit for cooling.  Other times they can be one and the same unit like with packaged air conditioners and heat pumps which does both jobs with one machine.  This makes for a great deal of variety in the choices of heating and air conditioning types that are available for use.

With use of a programmable or digital thermostat there is a high degree of control with a forced air system.  You can Set time-of-day and day-of-week settings to accommodate when the building is in use and when it is not.  There are also options for setting temperatures in certain sections of your home while other sections remain untouched.  All of this allows for lower utility bills, since only the rooms which are used frequently are heated or air conditioned.

Air conditioners and heaters utilized today have much higher energy efficiency ratings than those of years past; couple this with a well maintained, properly sealed, insulated and balanced duct system and the energy-savings increase even further.

Forced air systems cost anywhere from 40% to 60% less to install than comparable radiant systems.  They also offer special features such as filtration systems and ultra-violet germicidal lights, which can keep your indoor air clean and healthy.

Carney Plumbing, Heating & Cooling is an air conditioning and heating company in Horsham that provides quality HVAC services to each client.  Let us assist you in determining which forced air system is right for your unique needs.

Problems Caused by Low Refrigerant in an Air Conditioning System

Monday, August 6th, 2012

Having the proper refrigerant level of an air conditioning system is one of the key components to having properly cooled indoor air.   The AC specialists at Carney Plumbing, Heating & Cooling can easily diagnosis the AC problems which could be a result of low refrigerant levels get your system back up and running in no time.

Low Refrigerant Levels Mean AC Problems

One of the most common signs of low refrigerant levels is having an air conditioner that only blows warm air or one that does not sufficiently cool an entire indoor space, leaving some rooms which are warmer than others.  This is because refrigerant is what creates the cold air, and without enough of it, you can never have enough cold air.

Frost build-up or icing around the condenser coils in the outdoor unit can mean a refrigerant leak has caused low refrigerant levels.  Because ice build-up restricts air-flow, this can mean less cool air flowing into various rooms.  Low levels of refrigerant can cause coils to drop in temperature which then creates frost or ice on the coils.

An AC system that will not turn on could also be a result of low refrigerant levels.  Newer HVAC systems have built-in safety controls which detect certain changes in how internal systems function and as a safety precaution, shuts down the air conditioner in certain circumstances rather than continuing to run and further damaging other internal mechanical or electrical systems.

These are some of the main AC problems caused by low refrigerant levels.  It is important to have a professional Harleysville  air conditioning company such as Carney Plumbing, Heating & Cooling assist you with your air conditioning concerns.  Our AC technicians provide air conditioning services such as air conditioner maintenance and repair, including fixing refrigerant levels and charging refrigerant.

Central Air Conditioning FAQ’s

Monday, July 23rd, 2012

Central air conditioning is a great convenience, but it can also generate a number of questions. If you’re experiencing any trouble with a central cooling system or are wondering what to look for in a system, keep reading. We’ve gather some information to keep you informed and confident about the purchase and use of your Perkasie central air system.

What is a Central Air Conditioner?

This is a basic one, but many people are unclear on what exactly makes up a central A/C. There is a central unit containing the compressor which cools the air. This air is then forced through a ductwork system that distributes the cooled air throughout the structure. Blowers push the air through, and they pass through grated vents located in the walls or ceilings of a building.

How Do I Decide What Central System is Right for Me?

The best way to ensure that you are buying a properly sized central air conditioner for your home is to have an HVAC technician come and evaluate your living space. It is just as inconvenient to wind up with an oversized unit as with an undersized one, as this will result in clammy air that was cooled too quickly to be properly dehumidified. Cooled air will be over produced and wasted, lowering efficiency. An HVAC technician’s help will take the guess work out of choosing your system.

Why Won’t My Central Air Conditioner Cool?

There are a number of problems you could be experiencing if your central air conditioner is no longer cooling or is not performing at the level it once did. Checking your air filters is a good place to start. If they are dirty they will not let cooled air pass through efficiently and will need to be replaced or cleaned. Your refrigerant level may also need to be adjusted, or your fan could be running while your compressor is inactive. Another possibility are leaky ducts. Again, the best way to ensure that everything is working properly with your central system is to have a qualified HVAC technician perform an inspection.

When you invest in a central air conditioning system you should plan on protecting that investment. Failure to do so will result in subpar performance and damage to the system. The best way to keep your Perkasie central air conditioner working like new is with regular maintenance. Call the professionals at Carney Plumbing, Heating & Cooling with any concerns you have with your home cooling system.

Air Conditioning Tip: Indoor Air Conditioning Components

Monday, July 16th, 2012

Air conditioning in Lansdale is a modern convenience that we can easily take for granted as long as all the parts are working well.  In every unit, no matter the size, the basic process is one of extracting heat from the conditioned space and moving it to the outside, leaving cool air in its place.

This process easily divides into indoor and outdoor components.

Air Conditioning 101

Based on the principal of thermal energy which states that heat gravitates toward cooler temperatures, compounds known as refrigerants are moved through a closed loop system, repeatedly contracting and expanding between liquid and gas forms, alternately releasing and absorbing heat along the way.  The particular chemicals are selected for their abilities to transform from one state to the other at low temperatures.

While the refrigerant evaporates into a gaseous state within the looped system, it absorbs heat, removing the stale air from the space being conditioned and evacuating it to the outdoors. The warm air is pulled through ducts to meet with the cooling loop.

Ductwork

The cooled air is distributed through ducts or tubing and released into individual spaces.  Additional ductwork is required to remove the stale air and pull it back to be reconditioned as it passes over the loop containing the refrigerant.  The air is moved in both directions by a blower, usually electric and sized to handle the amount of air no matter the building.

Ductwork is also sized to handle appropriate volumes of air. To maintain efficiency, large trunks distribute along central lines to smaller ones reaching farther out. The return air is usually taken from common areas.

The grates are found in the walls, floors and often as part of the dropped ceiling. When combined with a forced air heating system, the total energy use is much more efficient.

Looped Coils

The refrigerant is enclosed in a loop where it can expand and contract to make its transformation from gas to liquid and back again.  To change into a heat-absorbing gas, it travels through the evaporating coils, an intricate series of delicate fins that meets with the ductwork to regenerate the conditioned air.

An exchange valve allows just the right amount of liquid refrigerant into the evaporator coils.  If there is too much, the tube is flooded too tightly to allow expansion of the molecules and room to attract the heat.  If too little, the process is inefficient.

Cool Maintenance

When set up and maintained on a regular basis, the system functions with little attention and over sight. To schedule a maintenance appointment today, give Carney Plumbing, Heating and Cooling a call!

Why is My Central Air Conditioner Making Noise?

Monday, July 9th, 2012

A 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.
