Spring Maintenance Tips For Inside the House

May 13th, 2011

Spring has sprung, and for homeowners that means more than just spring cleaning; it’s also the opportunity to take care of some home maintenance tasks. It may not be a ton of fun, but proper home maintenance is essential to keeping your home attractive and in good repair, as well as retaining its resale value.

Some simple maintenance once a year can also help avoid costly repair bills down the road. Below are a few tips on keeping the inside of your home maintained. Most of these are quick projects that can be done in your spare time over the weekend.

Ventilation, Heating And Cooling Tips:

Clean out your stove’s exhaust hood and change the filter. This will help the system to keep running efficiently and prevent damage to the motor, so that your kitchen is always well ventilated. A properly functioning kitchen exhaust system can also help prevent fires.
Change the furnace filter. The heating season may be behind you, but it will get chilly again before you know it. Changing your filter now as part of your spring maintenance will ensure that you don’t forget to do it in the interim, so your house will be properly heated when the chill of winter returns.
On the flip side, have your air conditioning system inspected by a professional. They can perform routine maintenance on the A/C system and make any necessary repairs. Taking care of this early in the spring will help make the hot summer months much more comfortable in your home.

Electrical Tips:

Hire an electrician to inspect the wiring and other components of your home’s electrical system. You can also do this yourself if you’re savvy, but unless you have experience, professional assistance is strongly recommended in order to avoid injury.
Have a look at your extension cords and power strips around the house. Replace any that are damaged or worn.
Check light fixtures to ensure installed bulbs are of the correct wattage. Using the wrong wattage bulb can cause electrical shorts, or draw more power than you need, making for an unnecessary expense. Consider replacing incandescent bulbs with compact fluorescent light (CFL) bulbs.

Safety Tips:

Clean all smoke and carbon monoxide detectors, and replace the batteries.
Have your fire extinguisher inspected to ensure it works properly. Replace as needed.

By making time to perform these relatively simple tasks in the spring, you can help keep your home safe and comfortable, while also decreasing ownership costs in the long run.

Do Low-Flow Toilets Work?

May 11th, 2011

Low flush toilets have been available since 1994 and are highly recommended both by the government and multiple green organizations to help reduce the water use in your home. But, the big question you probably have is whether these highly popular alternatives to regular toilets in fact work.

The Numbers

To start with, low flush toilets use less than half as much water to flush as a normal toilet. The average standard toilet uses 3.5 gallons per flush, while a low flush toilet uses only 1.6 gallons per flush. Some new toilets even use less – with the new High Efficiency Toilet (HET) standards setting the maximum flush capacity at 1.3 gpf.

While those toilets did not always perform to optimal standards when they were first released 17 years ago, they have come a long way and now operate almost identically to standard toilets. In fact, most public and restaurant restrooms built in the last 15 years now use these types of toilets instead to save money.

Choosing a Model that Will Work

There are a number of ways to measure different toilets. Just like almost any fixture, the manufacturer, design, and construction of a low flush toilet will determine how well it works. So, while for the most part low flush toilets work like normal toilets, you should take some things into consideration.

To start with, you must choose between either a siphonic or wash-down style toilet. The siphonic toilet uses much more water in the bowl, but as a result has a lot higher chance of clogging. The wash down method uses far less water in the bowl and does not clog as much, but the result is a somewhat tougher to clean interior of the toilet.

Pricing

The lowest prices may not represent the best low flush toilets on the market, but neither do the highest prices. Look for mid-range prices from competitive manufacturers. For less than $300, you can often buy a solid low flush toilet that will not clog any more often than a standard toilet and will save a tremendous amount of water and energy each year by reducing the amount of water flushed.

Low flush toilets are effective, inexpensive and largely popular for a good reason – they work. So, if you are remodelling a bathroom or simply want to make a change to the toilet you currently have, consider installing a low flush toilet to take advantage of green energy technology that is freely available for your bathroom.

How Much Water Will I Save with a Low Flow Toilet?

May 9th, 2011

There are many reasons why you might want to save water in your home. Not only does it save you money, cutting down on your annual water bill, but it allows you to do your part in reducing the impact of modernity on our environment. And of all the appliances and plumbing fixtures in our homes, the toilet is among the worst offenders when it comes to wasting water.

That is why the advent of the low flush toilet has been very well received. While the 1.6 gpf toilet (standard toilets are 3.5 gpf) was originally invented in the 1990s, it is only now becoming more widespread as issues with things like clogging and multiple flushes were commonplace with the earliest models.

So, how much water can a low flush toilet actually save you? On average a 3.5 gpf toilet uses around 27,300 gallons of water per year. By comparison the 1.6 gpf toilet uses only 12,500 gallons per year. That is less than half as much water. With the average toilet using up to 30% of the daily water flow in a home, it is a fantastic way to cut back on your environmental footprint, and if your water bills tend to be high, it will severely reduce them as well.

Other Ways to Save Water

Low Flush Toilets are a great way to cut back on the amount of water we use in our homes, but there are other ways as well. In terms of fixtures, low flow shower heads are very popular right now and can help to cut back another 15% of your annual water use. You can also purchase lower flow faucets for your kitchen and bathroom sinks. High quality hot water heaters that provide hot water as needed are also good for reducing water use as you will not need to leave the faucet or bath running for any period of time.

Whether you want to cut a few dollars from your monthly bill or simply want to do your part to protect our environment, a low flush toilet is definitely the way to go, especially if you are remodelling or moving into a new home and the choice is there for you to take. It may still be good to compare the price of a regular to low flush toilet if you already have a working toilet in your home, but for new installations it is almost always a good deal.

What Is SEER?

May 6th, 2011

If you’ve been looking at air conditioners, you’ve probably noticed that they all seem to have a SEER rating. But what does this actually mean?

The SEER, which stands for Seasonal Energy Efficiency Ratio, is a measure of how energy efficient a particular air conditioning model is. So when you’re shopping around for the best deal on an air conditioner for your home, this is something you’ll absolutely want to pay attention to.

Interpreting SEER Ratings

The SEER rating system is relatively simple – the higher the SEER, the more energy efficient the product. But because a higher price tag typically comes with a higher SEER rating, it’s important to know just how much more efficient a higher rated unit will be. It helps you decide whether paying significantly more for a higher rated unit is worth it in long term savings. Will it actually save you enough each month to make up for the difference in price?

Evaluating Your Energy Usage

A big factor here is how much you will use your air conditioner. If you live in a place with very hot and humid summers where the air conditioning runs constantly, you’re probably best off with the highest SEER you can find. When you consume that much energy to keep your home cool, you want to get as much as possible out of it, and that’s what a high SEER model can do for you.

On the other hand, if you live in an area that doesn’t have the harshest summers, you may be better off with a slightly less efficient (and therefore cheaper) model. Keep in mind, too, that the actual percentage increase in energy efficiency goes up by smaller and smaller increments the higher in SEER ratings you get. For instance, while a 10 SEER unit may be almost 20% more efficient than an 8 SEER model, a 12 SEER is only about 10% more efficient than that 10 SEER.

Finding the Right Balance

The best way to decide what SEER rating is best for you is to determine the annual cooling costs with your current unit and then calculate your savings in dollars based on the percentage each model would improve your efficiency. If you don’t currently have an air conditioner, this can be a bit tricky, but a professional contractor or air conditioning salesman can help you estimate your total monthly cooling costs with the various units.

2011 AC Federal Tax Credits

May 4th, 2011

You’ve probably heard many arguments for why you should purchase an energy efficient air conditioner. They may cost a bit more up front, but they’ll save you money in the long run by cutting down on your monthly energy bills. They’re also better for the environment because their lower energy usage means less fossil fuels are burned to keep them running.

But there’s another reason energy efficient AC units are better buys than your standard alternative. There are Federal tax credits available to consumers who purchase them. This tax credit can more than make up for the higher purchase price of the units, allowing you to enjoy your monthly savings much sooner and know you’re doing your part to protect the environment.

How to Qualify

In order to qualify for 2011 air conditioning Federal tax credit, you need to purchase an appropriate energy efficient AC system. Your HVAC contractor or salesperson can tell you which models and units qualify for this program. Just make sure you save all documentation and proof of purchase in case you need them to validate your claim.

The AC units that qualify you for this tax credit include those with a SEER (seasonal energy efficiency ratio) of 16 or greater and an EER (energy efficiency ratio) of at least 13. These two numbers are the best and clearest indicators of the overall energy efficiency of the product and can easily be found on the packaging for any air conditioning unit. While a 16 SEER is very good, it is not the highest rating currently available, either, so you won’t be forced to buy the most expensive model available to get your credit.

Credit Details

The tax credit is good for up to 10% of the purchase price of the unit up to $300. Keep in mind, though, that you can only claim up to $500 lifetime towards this program. So if you’ve previously claimed $250, you can only claim an additional $250 for 2011. That’s still a significant savings, though, and well worth looking into if you’re in the market for a new AC unit or system.

So if you’ve been thinking about upgrading your AC system, but haven’t quiet gotten around to, now may be the time to take advantage of this great tax credit opportunity before it’s too late.

Meet One of Our Best!

Hard work is paying off for Keith Linde. After five-and-a-half years as a Carney apprentice, Keith earned a promotion to technician in December. Rather than going on service calls with a senior employee, Keith can now tackle any job on his own. “You’ve got to climb the tree to get to the next level,” Keith says. He understands the

Keith Linde

challenges the company’s current apprentices face, but he knows they’ll succeed, just as he did.

Keith first started with Carney while he was still a student at North Montco Technical Career Center in Lansdale. While enrolled in the HVAC program, Keith worked two days a week at Carney and spent the other three days in classes. HVAC has been a comfortable choice for Keith right from the start. “I’d rather do this than anything else,”
he says. “Ever since 9th grade when we [got exposure to] all the building trades, I liked HVAC the best.” The combination of HVAC and Carney gave Keith an easy transition from school to the workforce: He stepped into his job here immediately upon graduation from Montco.

Keith’s favorite part of the job is repairing a heating system that has broken down. “It’s very satisfying to restore a customer’s comfort,” he says. Keith lives in Lansdale, which is also where he grew up as the second of four brothers. Two of his brothers are now expecting their first children, and Keith is excited to become an uncle. When Keith’s not working, he enjoys being with friends and riding his Kawasaki Ninja XZX6R motorcycle.

We here at Carney are very proud of Keith and his accomplishments at our company. It has been a pleasure to have him on our team!

Mechanical or Forced Ventilation v. Natural Ventilation

May 2nd, 2011

Just about everyone can agree that effective ventilation is essential to maintaining a healthy indoor living environment. But exactly what does this entail? There are quite a few ways to circulate air throughout your home, and each method is appropriate for a specific situation.

Benefits of Natural Ventilation

Natural ventilation, of course, can be achieved simply by opening a window. But there’s actually a lot more to it than that. If you really want to ventilate your home through natural means, then you’ll have to learn to take advantage of the differences in pressure in different areas of your home.

One way to do this is to use cross ventilation. This means opening windows or doors on both sides of your home and allowing the outdoor air to blow through, carrying stale, indoor air out the other side. A more sophisticated version of this is stack ventilation.

In a two-story home, stack ventilation can be achieved by opening the windows on the bottom floor on one side of the house and on the top floor on the opposite side. Because of the differences in outdoor air pressure, air will be sucked in through the lower floor windows and out through the upper ones.

Why Natural Ventilation Is Not Always Practical

These types of natural ventilation can be extremely effective when it comes to both cooling an indoor environment and removing indoor air contaminants. Unfortunately, allowing outdoor air inside unimpeded allows outdoor contaminants easily as well.

On particularly hot or humid days, natural ventilation can’t reduce the indoor temperature enough to make it comfortable indoors. While a light breeze is enough to take the edge off on a moderate spring or summer day, more is needed when the weather is extreme.

Types of Mechanical Ventilation

When you think of mechanical ventilation, you probably jump right to large central air conditioning systems. But that’s certainly not the only type of effective mechanical ventilation available. In fact, mechanical ventilation can be performed by just about any type of fan on the market, and while operating a fan is certainly more expensive than opening a window, it’s still much more affordable than running an air conditioner all day long. Fans can also be used in combination with natural ventilation to achieve better results than either system could on its own.

Geothermal vs. Solar

April 29th, 2011

If you are looking for a more environmentally friendly alternative to the traditional methods for home heating, you will probably consider both solar and geothermal options. Each of these relies on a great renewable resource to function and can be an excellent option depending on your specific circumstances. Of course, both geothermal and solar heating have limitations as well, so it is important to take these into account when you are evaluating your options.

A geothermal heating system works by extracting heat from the ground and transferring that to the air in your house. This occurs when heat is absorbed by a fluid flowing through a closed loop of pipes beneath or next to your home. The fluid then returns to your home, where the heat is extracted by a compressor and distributed throughout the house by an air handler.

This uses very little energy relative to a conventional heating system, as you only have to power the condenser and the air handler. The heat is not generated by the system but merely harvested, so total energy costs are quite low. However, the installation cost of a geothermal heating system can be many times what a conventional heating system would cost.

Solar heating relies on solar collectors to gather the heat from the sun. This heat is then passed into a system of heat pumps and heat exchangers so that it can be adequately distributed throughout your house. The installation of heat collectors, of course, is quite expensive as well, while the cost of running the system is generally low just as with the geothermal heat pump.

One advantage to opting for a solar heating system is that you can lease the equipment rather than buying it in some areas. This means that you do not have to pay the high installation costs and only pay a monthly fee to use the equipment which is usually comparable to what an average heating bill would be if you had a furnace.

But you also have to keep in mind that you need to have enough space to put up an adequate number of solar collectors to keep your house warm all winter. This often means giving up a lot of land, and if you have a lot, that is fine. But it is still something you need to take into consideration. Also, you need to make sure that the area you live in gets enough direct sunlight to make solar heating a viable option. Otherwise, you will be paying to run a backup system much of the time anyway.

Why Install a Ductless Air Conditioner?

April 27th, 2011

As you explore your options in terms of a new home air conditioning system, you will probably have to decide whether you want a system that uses ducts to get the cooled air around the house or one that is considered ductless. Each type of air conditioning system is appropriate in certain situations, so it is important to understand the benefits of each before you can make a decision.

Duct air conditioning systems are the more traditional type on the market today. They generally consist of an outdoor compressor and condenser unit and an indoor air handler. The outdoor unit passes the cooled air through ducts to the air handler, which then takes over circulating the air through the house and back out to the condenser again.

It makes sense to install this type of air conditioning system if you have a large house or if you have ducts already in place. Duct air conditioners can cool a moderate to large sized house quite effectively and they can also be coupled with zone control systems to give you multiple climate zones within your house.

Ductless air conditioners, as their name suggests, do not rely on a system of air ducts to get cooled air distributed throughout your house. Instead, these types of systems use refrigerant lines to transfer coolant from the outdoor compressor to the indoor, wall mounted units. Each of these indoor units can take care of cooling one or two rooms, but in order to cool an entire house with one of these systems, you will need to install multiple indoor units.

However, these multiple indoor units can all be connected to the same outdoor compressor, and they can also be controlled independently. That gives you much greater control over which parts of your house are cooled and how much energy you are using to cool areas that may or may not be occupied.

Ductless air conditioners are generally more energy efficient than ducted ones, but their real advantage comes from the facts that they can be installed even in places where air ducts do not exist or cannot go. If you do not already have ductwork in your house, installing a duct system will add considerably to the price of installing a ducted air conditioning system. In a case like this, a ductless system is much easier and cheaper to install and certainly makes more sense.

Why Select a Two Stage AC vs. Single Stage Air Conditioner

April 25th, 2011

When you are in the market for a new air conditioner, one of the decisions you will have to make is whether you want a two stage system or one that only functions in a single stage. Of course, before you can make a decision about this, you need to know what all of this means.

A single stage air conditioning system is probably what you are most familiar with. They have been around for longer and can be found in a wide variety of locations. Single stage air conditioners come on at full capacity when the temperature in your home rises above the preset level on the thermostat. Once they have effectively cooled the house, these types of air conditioners shut off until the temperature works its way back up again.

Two stage air conditioners, on the other hand, can function at either 67% or 100% of capacity depending on exactly how warm it is in your home. What that really means is that if the temperature in your home is only a little above the thermostat’s preset limit, the air conditioning system will come on at 67% and gradually cool the house to keep it right in a comfortable range.

However, if you have not been home for a while and your home has gotten very warm inside, your air conditioner will come on at full power to get the temperature down quickly. What this really means is that your air conditioner will be running more than a single stage air conditioner because it will sometimes not be using all of its power to cool.

The end result of using a two stage air conditioner is that you will receive a relatively continuous flow of cool air throughout your home. A two stage air conditioner will send in a steady but smaller stream of cooled air as opposed to the large blast of cold air you would get from a single stage system.

This results in a more consistent and comfortable environment overall, and it also makes it possible for the air conditioning system to dehumidify your house more effectively. When the air is cooled too quickly, the dehumidification system does not always have time to do its job. But with the longer cooling cycles of the two stage system, there is plenty of time to make sure the right amount of humidity is removed from the air.
