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.

Dirty Air Filters and Air Conditioning Repairs

Tuesday, June 11th, 2013

Your 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.

Call the Lansdale, PA air conditioning repair specialists at Carney Plumbing Heating & Cooling today if you have any questions!

Using Your Air Conditioning System Efficiently

Thursday, May 16th, 2013

One of the most frequently asked questions we get during the hot summer months concerns how to use your air conditioning in Lansdale, PA more efficiently. While we cannot control the seemingly ever-rising costs of energy, we can control how we use that energy to keep our homes cool, crisp, and refreshing. And that’s what today’s post will be about. There is a great variety of ways you can use your AC efficiently, and we’ll only be able to touch on the topic only briefly today. If you’re in need of professional air conditioning services in Lansdale, PA, do not hesitate to get in touch with one of the friendly technicians at Carney Plumbing, Heating & Cooling today.

  • Clean and replace your air filter on a regular basis: We can’t emphasize this simple task enough. Too many perfectly good ACs are ruined every year because of homeowner neglect. While you rely on the professional skills of your technician for the majority of maintenance duties, cleaning and replacing your air filter is one of the few things you can do, and it’s critical to the longevity of your AC as well as to the energy efficiency with which it operates. A dirty or clogged air filter can neither prevent the accumulation of dust and debris on sensitive mechanical components nor allow cool air to pass uninhibited.
  • Enroll in a preventive maintenance program: Prevention is incredibly important as a way to stave off unnecessary repairs and premature replacement. Routine professional maintenance includes comprehensive inspection to recognize problems before they start, cleaning to ensure that your system operates well, and adjustments to ensure that it’s operating efficiently and safely.
  • Install a programmable thermostat: If you have a manual thermostat, you’re missing out on the benefits of a digital programmable model. It allows you to boost energy efficiency without sacrificing comfort when you create a schedule of cooling that works around your lifestyle. Automatic, gradual cooling also cuts down on drastic manual changes that can cause wasteful energy consumption.

If you’re looking for more ways to make your air conditioning in Lansdale, PA more energy efficient, call Carney Plumbing, Heating & Cooling today.

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.
