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.

Comparing High-Efficiency and Mid-Efficiency Furnaces

Wednesday, January 18th, 2012

Whenever you are in the market for a new furnace for your Perkasie home, there are many models to choose from.  Many of the furnaces manufactured within the last few years are high-efficiency furnaces with a high AFUE rating (AFUE measures the amount of fuel the furnace converts into heat). When people refer to a mid-efficiency furnace, they are usually talking about older furnaces.

Single-stage furnaces were considered to be an efficient heating system when they were manufactured, but compared to newer furnaces, they use up a lot more energy than they need to. Single-speed furnaces are designed to run at full capacity until the temperature inside the home reaches the thermostat setting. After they shut off, the home not only loses heat, but the furnace will also take longer and burn more fuel when it cycles on again.

Newer, two-speed and multispeed models run consistently at lower speeds, and the ones with variable-speed blowers are even more efficient because they can operate at various levels. These models will also automatically adjust to the thermostat to maintain a constant temperature, which saves energy by keeping the home at a consistent temperature so that there’s little heat loss.

When shopping for a new furnace, keep in mind that the AFUE ratings for multispeed and variable-speed furnaces only determine the efficiency of the actual furnace. If you are upgrading your old, mid-efficiency furnace to a high-efficiency furnace, you should make sure that your Perkasie home is properly insulated and sealed.  You could also consider upgrading any older doors and windows to more efficient double-paned ones, or you can also install storm doors and windows.

Causes of Delayed Furnace Ignition

Wednesday, January 11th, 2012

Delayed ignition is usually accompanied by a loud banging or booming sound that resembles a small explosion in your gas appliance. In your New Britain home’s furnace, this can be terrifying and should never be ignored.

What Causes Delayed Ignition

Delayed ignition usually happens when you first turn on your furnace, often after a long delay between use, so usually early in the fall or late in the spring when you don’t necessarily have it on every day of the week.

What happens is moisture builds up over the course of a period of inactivity and begins to corrode the firebox in your furnace. That corrosion builds up to the point that it starts to block the ports that feed gas into the burners. When these ports get blocked, the burners down the line cannot light and when you flip the switch, they won’t light immediately.

Of course, while rust and corrosion are a risk, lint and dust can be equally problematic (and are more common if you don’t have your furnace cleaned properly each fall). Sulfur build up is also a possibility, as it is left behind by burning natural gas. It will appear as a layer of white on the surface of the burners or the pilot light.

When all of this happens and the ports are not cleaned properly, gas will build up in the chamber after it is turned on and, when it finally ignites, create the small boom sound. It doesn’t just sound like an explosion – it is one – and if ignored, it can become incredibly dangerous.

Solving the Problem

Delayed furnace ignition is an easy problem to avoid. All you need to do is have your furnace cleaned properly before turning it on each fall. A New Britain heating technician will clean the burners and ports and remove any dust, lint, rust or sulfur buildup that might block ignition and cause a delay.

When replacing your furnace, look for a device with corrosion resistant materials. You can learn more about these when it comes time to replace your furnace from a technician. Most importantly, be careful. It may be a small problem now, but if left to build up over time, that small boom can become a much larger one.

5 Ways to Improve IAQ and Reduce Air Pollution

Wednesday, December 28th, 2011

Your Horsham home may be haven for pollutants that can cause irritation to the upper respiratory system of anyone who comes inside. These allergens and pollutants are easy to remove however by taking some simple steps such as the five listed below:

  1. HEPA Filtration – Step one is to use HEPA filtration to remove as much of what is on the floor as possible through vacuuming. HEPA vacuum cleaners can remove years of cleaners, solvents, dander, mineral build ups and other toxins that tend to accumulate in spaces that normal vacuums cannot reach. It may be a bit of an investment, but a high powered vacuum cleaner can have a tremendously positive impact on your lifestyle and reduce pollutants.
  2. Stop Outside Stuff from Coming In – Some of the worst pollutants your home will face are from outside. So, make sure you have doormats at every door and that your family and friends remove their shoes before coming inside. You can have a second mat inside as a friendly reminder that cleaning the shoes is not an option but a strict necessity.
  3. Humidity Helps – Humidity levels between 30% and 50% reduce the presence of dust mites, molds, bacteria and many other indoor pollutants. Air conditioning in the summer is helpful to reduce humidity, though a dehumidifier is recommended for those days when the temperature doesn’t justify full blown air conditioning. Additionally, look for sources of excess humidity like leaky pipes, standing water, or clothes drying.
  4. Radon Testing – We’ve recently discovered that Radon is the second leading cause of lung cancer in the United States each year and can be present in almost any home. It is not a location specific pollutant, so it’s important to have your indoor air tested for Radon as soon as you move into a new home. Once testing is done, have any problems repaired immediately.
  5. Cut the Chemicals – There are a number of high quality household cleaners that don’t contain chemicals. Avoid ammonia, bleach and other chemical laden cleaners that can inflame allergies and pollute the water supply. Your home will be just as clean and you won’t feel uncomfortable afterwards.

Proper cleaning and careful selection of compounds and what goes into your air will help you avoid creating new air quality problems in the house. Done right, this process will make everyone in your home feel more comfortable.

Make Your Heating System More Energy Efficient

Wednesday, November 16th, 2011

Efficiency is what you want when it comes to heating your Abington home. You want a furnace that provides the greatest degree of accurate indoor comfort while at the same time operating at peak efficiency to reduce energy usage and lower utility bills. That’s seems like a lot to ask of a simple mechanical system but you should expect it out of the furnace in your basement, attic, or mechanical room.

It is especially important today as energy costs have steadily increased, including electricity, natural and propane gas, and oil. The best way to combat rising prices is to have a furnace that uses less energy. It is a simple statement but one that bears repeating: higher efficiency equals lower operating costs.

Here are some ways to make your heating system more energy efficient:

  1. Clean or replace furnace filters on a regular basis. A dirty or clogged filter will make your furnace work harder and become much less energy efficient. Monthly or quarterly cleaning or replacements are easy to do and will result greater operating efficiencies.
  2. Inspect your home’s ventilation system for accumulation of dirt, dust, or debris. Have you recently added new carpeting? Do your pets shed? Is there a large number of people living in your home? If you answered yes to any of these questions you may need to inspect your ventilation system.
  3. Remove obstructions from around vents and grilles. You need a clean path for air to flow into and out of rooms. Restricted airflow makes your furnace work harder and become less energy efficient.
  4. Consider an upgrade to a two-speed or variable speed furnace. Most older furnaces operated on one speed, which cycled on and off and consumed a lot of energy. Today’s furnaces operate at lower speeds, consuming less energy and often remaining on to keep a steady airflow and prevent constant on and off cycling. These newer furnaces are much more energy efficient and cost less to operate.
  5. Adhere to a regular schedule of planned furnace maintenance. If you don’t clean and inspect your furnace on a regular basis, schedule service calls with a local qualified heating contractor. Your contractor will likely have a service agreement plan to fit your budget, which allows for annual inspections, priority emergency service calls, and discounts on parts and services.

Besides saving on energy costs, your efficient furnace will leave a smaller “carbon footprint.” Your efficient furnace will exhaust less carbon dioxide into the atmosphere and maintain a more “green” profile. And being ecologically friendly can be just as important as saving money.

You can be assured that an energy efficient heating system will keep more money in your pocket this fall and winter.

Common Water Line Problems

Monday, November 7th, 2011

Everyone needs water in Abington. It keeps us clean, provides us with a clean drinking source and helps us cook food and wash clothes. So, when a problem occurs with the water line, it can be disruptive to every aspect of everyday life. Here are some common water line problems and solutions you can implement to solve them as fast as possible:

  • Burst Pipe – The biggest problem you can have is a burst pipe. This is a major problem and one that needs to be solved immediately. If your pipe bursts or starts to leak, turn off the main water supply immediately and call an emergency plumber. You’ll want to have it patched as soon as possible to return normal water service to your home.
  • Noisy Pipes – Noise in the pipes is a slightly less disastrous problem but it can lead to bigger problems down the road if not dealt with. Usually, it is due to air in the pipes which can create a loud banging sound. If your pipes are vibrating or banging, the easiest solution is to turn off the water supply and drain your pipes completely, then fill them back up to remove the air build up.
  • Water Pressure – Low water pressure can be due to a number of problems, from a small leak somewhere to an issue in the incoming water supply. If you notice water pressure dropping in your home, call a professional to inspect the problem and offer potential solutions.
  • Sediment in the Pipes – If suddenly you are seeing excess sediment, rust, or other debris in your water it is probably from an aging pipe. While this doesn’t necessarily signal that your pipe is about to burst, it can be a sign of potential problems in the future. Build up from hard water or erosion can both be major problems if not fixed right away.

Water line problems can range from small nuisances to major disasters that threaten your entire home, but they should all be treated with equal import. If something happens to your water line, don’t waste time trying to track down a solution. Turn off the water supply and call a professional right away.

What Happens if My Heat Pump Loses Power?

Monday, October 24th, 2011

One of the advantages of having a heat pump in your Lansdale home is that they operate on electricity, so you don’t need to worry about having maintaining a supply of fuel to keep yours running. Where a furnace or boiler might call for you to purchase supplies of oil or natural gas, and a wood stove means keeping potentially messy firewood around, a heat pump runs cleanly on electricity.

Heat pumps are good at using electricity, too. They are often able to produce heat energy that can be as much as three times the electricity they draw to produce it. This means not just convenience, but also a big savings, just by virtue of using electrical power.

The risk there, of course, is that if and when the power goes out, so does the heat pump. That means when a big winter storm drops a tree on the local power line, things can get cold inside mighty quickly. For these situations, you should have a backup heating solution on hand to keep everyone comfortable in the short term. And, as a responsible homeowner, you likely already have this taken care of.

But what happens when the power comes back on? Can you just fire your heat pump right back up without missing a beat?

The short answer is “no.” You should not do that, for at least two reasons. First of all, after any power outage, you should always take care to turn on appliances gradually over a period of time rather than all at once in order to avoid a spike in demand at the power company, which can blow a grid. That’s just a general tip.

Specific to heat pumps, though, there is a unique concern. If the heat pump loses power for more than 30 minutes, the refrigerant can get too cold to flow properly, so turning it right back on can cause the whole thing to conk right out. Instead, do the following:

  1. Make sure the heat pump is off. You can do this during the power outage.
  2. Once power comes back on, turn the heat pump to the “Emergency Heat” setting. This will allow the compressor to warm up slowly and get the refrigerant warm enough to start flow freely again.
  3. Wait. The time you need to wait varies depending on the size and manufacturer of your heat pump, so refer to the manual. In general, you should wait at least 6 hours.

After this process, your heat pump should be ready to resume normal operation without issue.

Quick Tips From Perkasie: How to Save Money on Air Conditioning

Friday, August 26th, 2011

You’ve probably heard once or twice that the cost of running your air conditioner is more than that of any other single electrical device in your Perkasie house. That means you’re spending hundreds and possibly even thousands of dollars each and every year to stay cool. It’s well worth the investment as the risk of not having air conditioning is much too high, but there must be ways to cut the costs, right? With careful attention to how your AC operates and when you use, there are some things you can do to slash those costs. Here are a few of the easiest:

  • SEER Matters – What is this magical acronym you hear so much? SEER refers to how many BTUs your air conditioner can produce with a single watt of electricity. A low SEER device therefore uses a LOT more electricity to produce the same volume of cooling as a high SEER device. Since current devices offer SEER of 13 or higher (some are up to 20+), just about any upgrade will save you money relatively quickly if your current air conditioner has a rating of 8 or lower.
  • Program Your AC – If you have a single point analog thermostat, you’re wasting a LOT of electricity. You’re either paying to cool your house while it’s empty or you’re coming home to a roasting hot living space. Purchase a programmable unit and set the system to 85 degrees when you’re not home. With timers in most digital units, you can tell it when you’ll be home so that you walk into a cool, comfortable space without having to keep it cool all day long.
  • Use the Landscape to Your Advantage – Instead of relying solely on your air conditioner to keep the house cool in the summer, plant some trees and shrubs around the house to block the sunlight. Simply adding some shade to your property can directly reduce how much heat your home absorbs throughout the day and reduce how much your AC unit needs to work to keep you cool.
  • Ventilate Your Roof – A good third of the heat in your home is absorbed directly through the roof. To keep this heat from affecting the rest of your home, install a roof fan that ventilates the excess energy and keeps the attic at a steady temperature. Less heat up top means less cooling needed down low.

A good air conditioning system is effective no matter what the temperature does, so it’s easy to forget how big your bill will soon be. To avoid an overblown bill, keep an eye on your cooling and follow these simple tips to cut back on use. To get more energy saving tips, talk to your HVAC contractor.

How to Calculate Duct Size for an AC System

Friday, August 19th, 2011

Duct sizing for air conditioning is a complex process using one of three methodologies. The goal of duct sizing is to provide the perfect space through which heated and cooled air can travel around your Conshohocken home. Ducts should provide ample air flow to keep you comfortable without overworking your HVAC system or costing you an arm and a leg on your energy bill.

Methods Used for Sizing

There are three methods used for most modern duct sizing. The first is the Velocity Method. The velocity method takes into account the speed at which air flows through the ducts based on their general size. A series of equations is used to determine this, including duct cross sectional area, air flow rate and air speed. A much more detailed breakdown is available on the EngineeringToolbox.com for those interested in the math behind the process.

In general though, the velocity method allows contractors to determine the appropriate size and layout of ducts based on their application (residential, commercial, industrial or high speed) and their position (main or branch ducts).

Contractors may also use the Constant Pressure Loss and Static Pressure Recovery methods to design ductwork for your HVAC system. The constant pressure loss method tends to result in more components but provides a more accurate reading of the actual pressure loss in the system based on the materials used and the layout of your ductwork.

Static pressure recovery focuses on ensuring the same pressure level is achieved at all vents and inlets for the system. It is probably the most complicated sizing method, however, so it is rarely used for residential installations.

Simplifying the Process

Were we to break down the process into its core components, this is what a contractor would do when sizing your duct work:

  • Determine CFM for Each Room – using the Manual J for load calculations, they would determine the CFM. This is based on the (Room Load/House Load) x Equipment CFM. The entire house must be measured and load calculations completed before this can be done.
  • Friction Loss Rate – Friction loss rate is the (Available Static Pressure x100 / Effective Length).
  • Duct Sizing – Finally, the contractor will use a chart or software to select ductwork based on the friction loss and CFM calculated in the first two steps.

The goal of all of this math is to ensure that the system installed is exactly as large as is necessary to distribute heated or cooled air to the entire house. Incorrect measurements result in improper delivery of that air and a system that doesn’t quite get the job done.

How to Choose the Water Softener That Is Right for You

Friday, June 24th, 2011

If hard water is a problem in your home, the solution may be simpler than you think. There are many water softeners out there, and some of them can be quite effective at treating the water coming into your home in order to remove the minerals that make the water hard. However, there are plenty of distinct differences between the various products on the market as well, so you should take a closer look at your options before you commit to one system over another.

The first thing you need to know when you start looking at water softeners is how hard your water actually is. If your water is very hard, you will need a heavy duty water softener. But if there are only moderate amounts of calcium and magnesium in your water, you may be able to opt for a less powerful model.

You should also be aware of how much water you go through on a daily basis. You want to get a water softener big enough to handle the demands of your household, and you will not be able to do that if you do not know how much water you typically use.

Another difference between the various water softener models on the market today is the type of regeneration cycle they employ. You can opt for a timer regenerated water softener that will complete the regeneration cycle as often as you set it to. These models tend to be cheaper initially, but they can also cost more to operate and maintain in the long run because they will regenerate when the time comes whether it is actually necessary or not.

There are also meter regenerated water softeners that only go through a regeneration cycle once a certain volume of water has passed through them. These water softeners are specifically calibrated to the amount of calcium and magnesium you have in your water so they only go through a regeneration cycle when it is absolutely necessary.

One concern that many people have about using water softeners is that the most common types use sodium as a regeneration agent. That means that they exchange sodium for the calcium and magnesium in the water. If you need to limit your sodium intake, you may not want to be adding even this small amount to your water. In that case, you can purchase a water softener that uses potassium rather than sodium which can be just as effective at removing other minerals.
