Quick Tips From Anmore on How to Save Money on Air Conditioning

Monday, September 5th, 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 Anmore house. That means you’re spending hundreds 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 thermostat 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. If you have more questions, contact an HVAC contractor.

Choosing an Environmentally Friendly Refrigerant for Your Air Conditioner in Victoria

Monday, August 29th, 2011

For years in Victoria, we heard about how bad air conditioners were for the environment. Specifically, the liquid used in them to remove heat from air in your home tended to eat holes in the Ozone layer. Today however, air conditioners (along with every other appliance or device that uses refrigerant) have been upgraded to work with newer, better chemicals.

R-22 Refrigerant

While R-22 refrigerant is still used in devices sold today, it is being gradually phased out. According to the Montreal Protocol, R-22 refrigerant will no longer be allowed in new devices as of January 1, 2020 in the Canada (though it can be used to service existing devices via recycled or reused refrigerant). While the most environmentally damaging refrigerants such as HCFC-141b have been removed from the market, R-22 is still considered harmful to the environment if allowed to enter the atmosphere.

R-410A Refrigerant

So, if R-22 will soon not be permitted (and is not an environmentally friendly option), what is? Currently, the most common refrigerant used in new residential air conditioners is R-410A. It is one of the least damaging to the environment (and human health) and which could be used as alternatives to R-22. R-410A is a blend of different HFCs that don’t deplete the ozone. Sometimes called Puron, Forane, or Genetron AZ-20, R-410A is a good choice if you’re having a new system installed.

Other Alternatives

Of course, because R-410A is a hydrofluorocarbon, it does contribute to global warming and therefore is a risk to the environment, albeit in a much smaller capacity than older refrigerants. Recently, the EPA approved the use of HFO-1234yf – a chemical that pollutes 99.7% less than the current refrigerant used in car air conditioners. Whether it will be used in homes and commercial spaces remains to be seen, but the technology is advancing rapidly, allowing us to stay cool without sacrificing our planet’s health and future to do so.

Another alternative is to invest in an evaporative cooling system rather than a traditional air conditioner. These systems use no HFCs at all and therefore have zero impact on the ozone layer or global warming (other than the electricity they consume). They also use 80% less energy than traditional air conditioners. If you live in a dry, low humidity climate they are a great option.

Green Thinking for Fort Langley Green Thinkers

Monday, August 8th, 2011

There are a lot of media stories in Fort Langley about exciting new green buildings: LEED-certified buildings, net-zero buildings, buildings made out of recycled shipping containers, homes in New Urbanist communities, even “ultra-small” homes. But a new home can be pricey. Fortunately, though, all these innovative green ideas can be applied where you live right now. In fact, going green in your existing home might even be better for the environment than building a brand-new home.

If you wish your home could be LEED-accredited, focus on energy conservation and indoor air quality in your existing home. Upgrade to a high-efficiency furnace and air conditioner and consider adding central air filtration to your heating and cooling system. Install Energy Star appliances and WaterSense plumbing fixtures. For remodeling projects, use VOC-free paints and natural materials.

If you wish you had a “net-zero” home, consider geothermal – and insulate. Geothermal systems use 70% renewable energy and protect you against spikes in oil and utility prices. To increase your energy savings still more, tighten the “thermal envelope” of your home by identifying and sealing hidden air leaks and adding insulation.

If you wish you lived in a “recycled” home, get to know your local salvage yard. Many communities have “architectural salvage” shops and recycle/reuse areas in their landfills. When you do your next home improvement project, go shopping at your landfill first. This is not only great for the environment; it’s also great for your budget. Plus, you’ll end up with a creative, unique home. (Of course, make sure that you don’t re-use items containing lead, asbestos, or other contaminants.)

If you wish you lived in a New Urbanist community, start walking and biking in your own community. Experiment with replacing some of your car trips with walking or biking trips. If you find that your community isn’t pedestrian- or bike-friendly, work with local politicians to change this. Learn about your local public transportation options to see if you can fit them into your lifestyle. If you’re in the market for a new home, make location and proximity to work and shops a primary consideration.

If an “ultra-small” home looks like fun but seems impractical as a long-term residence, consider reducing the size of your own living space. If your kids are grown, it may be time to downsize to a smaller home that uses less energy. If you’re building a new home or an addition to your current home, build only what you need. Sometimes the greenest building decision you make can be deciding to build less.

(The “Not So Big House” website (http://www.notsobig.com) is a great resource for those interested in downsizing while maintaining a high quality of life.)

Most Commonly Asked Questions about Heat Pumps

Friday, February 25th, 2011

If you’re thinking about buying a new heat pump for your home, chances are you have some questions about these types of products and how they work. In fact, because these types of home comfort systems are relatively new to a lot of people, there are a quite a few misconceptions out there about how effective and efficient they can be.

Recently we’ve gotten some good questions from our readers, so we thought we’d like to pass along the answers so that others can benefit from the information as well.

If I Buy a Heat Pump, Do I Have to Buy an Air Conditioner Too?

That heat pumps are only able to heat your home is probably one of the biggest misconceptions about this type of equipment. Heat pumps work by extracting heat from the air in one place and transferring it to another. That means that in the winter, your heat pump is able to heat your home by taking heat from the outdoor air and moving it inside.

However, in the summer, the heat pump is able to do the same thing only in reverse. When you switch on your heat pump’s cooling function, it will be able to take the heat out of your indoor air and transfer it outside. In this way, the same heat pump system can keep your home warm in the winter and cool in the summer without you needing to purchase an air conditioner or other supplemental comfort systems.

If I Choose a Heat Pump System, Will I Also Need to Install Supplemental Heat?

That depends on what the climate is like where you live and how warm you like to keep your home. In general, heat pumps can keep any home comfortable as long as the outdoor temperature is above 32°F or so. If the temperature outside drops below that, you may want to have some type of supplemental heating system just in case. However, a heat pump will still be able to provide some warmth at these lower temperatures and you may be able to keep yourself comfortable with a simple space heater or too.

Also, remember that these colder temperatures are most common at night when you would probably have turned your heat down anyway. As long as you live in a relatively moderate climate, heat pumps can do a great job of keeping your home comfortable all year long.

How a Circulating Fan Can Save You Money and Help Your AC Keep You Cool

Monday, January 31st, 2011

If you already have a central air conditioning unit, you probably have not though much about having some ceiling fans put in as well. After all, why would you need a fan when your air conditioner can keep you as cool as you want all year long?

Well, the truth is that a ceiling fan can actually contribute a lot to your household even when you do already have the central air in place. It can also save you quite a bit of money when it comes to your monthly cooling costs, so there is really no reason not to look into getting a ceiling fan of your own.

Certainly the air that air conditioners distribute throughout your house is quite cool. But a ceiling fan will help to circulate it much more effectively. In fact, a good ceiling fan can make a room feel up to eight degrees cooler than it actually is just because of the cooling affect that moving air has on your body.

This means that you could set the thermostat on your air conditioner higher and still enjoy the same level of comfort that you are used to. You may already know that for every degree you raise your thermostat in the summer you will be saving up to 3% off of your regular energy bill. So if you can turn the air conditioning down by more than five degrees, you will surely be seeing some substantial savings.

Of course, you are still running the ceiling fan in place of the air conditioner, but the fan will use only a very small fraction of the energy that the air conditioner does. This all means that having a ceiling fan and using it wisely can help you cut your annual cooling costs dramatically.

And a ceiling fan will be useful in the winter as well. Since heat rises, you can turn your fan on backwards and it will push the heat that has risen to the top of your room back out along the walls and down. This means that you will be getting more for the heat you are paying for as well, making the ceiling fan a great money saver all year long.

How to Cover Your Air Conditioner for the Winter

Tuesday, November 23rd, 2010

604-630-7747

When you have an outdoor air conditioner, you may be wondering what to do about it when the weather turns. The truth of the matter is that plenty of people find that they can simply shut off the air conditioning unit at the end of the summer and then not think about it. This is not necessarily bad for your air conditioning unit, but should you cover it?

Air conditioners don't like to be left out in the cold!

There are a few benefits for covering your air conditioning unit, and there is even more than one way to cover it. For example, if you cover your air conditioning unit with a canvas or vinyl cover, you can keep debris out of it, which leads to a clean start when the weather turns again. You can also protect your air conditioner from falling ice through using a simple sheet of plywood, metal or plastic held in place with a few sand bags.

For the most part, air conditioners do not need to be covered. They are built to withstand extreme temperature changes, and they are not going to be damaged by cold weather. Furthermore, there is the issue where covering an air conditioner leads to small animals nesting in it, which in turn damages the air conditioner heavily by the time spring rolls around.

If you wish to cover your air conditioner, choose a flat sheet of plywood or sturdy plastic that is cut to be a little larger on all sides than the top profile of your air conditioner unit. Lay it on top of the air conditioner unit and weigh it down with a few plastic bags filled with sand and twist-tied closed. If you want to be extra sure that the sand does not get out, double or triple bag the sand bags.

While a vinyl covering can keep debris off of the air conditioner, the issue of having small animals drawn to the protected space is one that can lead to problems. If you want to use a vinyl cover, choose one from the hardware store that fits well, and make sure that you check it routinely throughout the winter for unwanted guests!

Covering an air conditioner for winter is something that takes only a small amount of time. However, you need to choose a solution that is right for you and right for your circumstances. This is something that can make a huge difference to your peace of mind this winter.
