Saving Money with Your Landscaping, and Air Conditioning in Mira Mesa!

Monday, April 23rd, 2012

Who knew that proper landscaping of your home could save you money?  It’s true!  Soon enough those hot, summer months will blaze through making us sweat in the heat of the midday sun.  All we want is respite from that heat, and maybe a cool drink to sip.  But our air conditioners in Mira Mesa will work harder and more frequently than we would ever want to in such direct heat and blinding light.  Since those hot summer days are still on the horizon and the beauty of spring is in full-swing, this is the time to prepare for the inevitable by giving the AC a break while at the same time saving money on utility bills.

Inspect, prune, and pay attention!  Get out in that garden and have a look at that AC unit!

  • Air conditioning maintenance, like cutting back any overgrown bushes or plants nearby, and removing any weeds growing near or over the AC unit, is essential in order to ensure proper air circulation is maintained in the space immediately surrounding the AC unit. It might even be prudent to place stepping stones or cement in the foot of space immediately surrounding the AC unit, to keep a good barrier between the unit and surrounding foliage.
  • Pull out that green thumb and plant some flowers or greenery surrounding but not too close to the AC unit, making it a part of the yard’s landscaping, rather than an eye-sore which stands out.
  • Get your air conditioner under the shade.  This can be done simply by adding trees or tall bushes near the AC unit, protecting it from the blazing sun.  AC units can also be moved to the North side of a house or other building, making sure they are under the shade during the heat of the day.  Ensuring an AC unit is in the shade can mean not only saving approximately 5% on cooling bills, but can also increase the energy efficiency of the air conditioning unit by upwards of 10%.
  • Add trees or tall foliage all around a property to provide shade directly on the home or building, which can additionally contribute to overall cooling of the yard and buildings being cooled.

Proper landscape maintenance near, upkeep of, and airflow to an air conditioning unit ensures that there is reduced wear and tear on the AC unit, helping it to run more efficiently for a much longer period of time.  Pay attention to your AC unit and it will provide a great service for many years.  Don’t hesitate to call Cal-West Air Conditioning for any clarification.

How Heat Pumps Can Help With Humidity in Del Mar

Wednesday, February 8th, 2012

Humidity is a big problem for a lot of families in Del Mar. When not properly controlled, excess humidity can lead to damage to your furniture, excess mold growth and dust mites. In the warmer months of the year, this is a big problem. Fortunately, if you have a new heat pump, you have a strong weapon against excess humidity.

Heat pumps have both cooling and heating modes. In the winter, when your heating mode is active, you likely don’t need dehumidification. In fact, you may need a humidifier to keep it from getting too dry in your home. However, in the summer, excess humidity can make everyone uncomfortable.

Air conditioning has long been a natural dehumidifier. Because the process works through evaporation and condensation, water can be extracted from the air by the device whenever it is on.

However, for your heat pump to truly provide the dehumidification you need to remain comfortable, it must first have a dehumidification setting – often called the “dry” cycle. During this cycle, the device will dehumidify your home, pulling air from inside the house and extracting moisture from it through the indoor evaporator coils.

Dry cycling is effective because it doesn’t draw new air in from outside to cool your home. It uses the same air already in your home and can therefore remove humidity over time. While new air is draw into your home through vents, the system is designed to continuously cycle the humidity out of the air and keep you from being uncomfortable.

Choosing the Right Heat Pump for Humidity Control

Not all heat pumps offer humidity control settings, so contact Cal-West HVAC experts about your needs before selecting a new model for your home. Make sure it offers the dehumidification options you’re looking for and can cover the full area of your home.

San Diego Heating Repair Question: What Causes Cracks in a Heat Exchanger?

Tuesday, January 31st, 2012

Furnaces are designed so that the heat – and the combustion byproduct produced inside – doesn’t interact directly with the outside air. This design is to ensure you have a safer furnace in your San Diego home that won’t inadvertently affect your family’s health.

The metal piece that separates the furnace heat from the outside air stream is called the heat exchanger. The heat exchanger performs a very important function, and if it is broken or cracked, it can’t work properly.

A cracked heat exchanger is very common problem with heating systems, as well as one that should be repaired as soon as possible. But what causes a heat exchanger to crack? Here are some of the most common reasons:

  • A long period of normal use. A furnace heat exchanger naturally expands and contracts with the heat of the furnace, over and over again as the furnace is turned off and on to heat the home. Over several years, this stress can crack the metal.
  • Poor air flow, often caused by dirty or obstructed vents, can result in poor air flow through the furnace. This overworks the furnace, which can crack the heat exchanger prematurely.
  • Poor, incomplete or improper combustion can also cause a heat exchanger to crack. When the combustion process is less efficient – which can also be a result of poor air flow — your furnace’s burners have to run hotter and longer to heat your home, which means extra stress on the heat exchanger.

Essentially, if a furnace is running at less than optimal efficiency for an extended period of time, the heat exchanger is put under additional stress beyond the usual and can crack prematurely. Therefore, the best way to prevent a cracked heat exchanger is proper maintenance, particularly keeping all vents clean and unobstructed and getting an annual maintenance inspection.

If your heat exchanger does crack, do not hesitate to call Cal-West Air Conditioning Inc. and get it repaired. The crack can allow potentially dangerous combustion gases to seep into your San Diego home, which can have a negative impact on your family’s health.

El Cajon Furnace Installation Guide: AFUE Ratings

Wednesday, January 11th, 2012

If you’ve been shopping for a furnace in El Cajon, chances are you’ve noticed that each furnace has its own annual fuel utilization efficiency (AFUE) rating. These generally range from 80% to the high 90% s and the higher the number, the more fuel efficient that particular furnace is.

But what does this number really mean and just how much should you care? Well, the AFUE rating should actually have a significant impact on your furnace purchasing decision, but that doesn’t mean that you’ll always choose the furnace with the highest efficiency rating either.

For one thing, you’ll have to recognize that not every type of furnace is capable of running at the highest efficiency levels. Oil furnaces, for instance, can’t compete with the super high efficiency gas furnaces on the market today. That’s not to say that an oil furnace might not be the best choice for you under certain circumstances, but it does mean that you should take a close look at your furnace usage before you make a decision.

If you do choose a gas furnace, you will of course have the option of getting one that can reach up to 97% or so efficiency. However, that may not always be the best choice either. If you live in a place where with very harsh, long winters and you’re going to be using your furnace heavily, then it’s definitely worth investing in a higher AFUE furnace that can save you considerable amounts on your monthly heating bills.

But if you don’t use your furnace too often as your area has more mild winters it’s probably not worth it for you to invest in such a high efficiency product. That’s because the higher the AFUE of the furnace, the more expensive it is to purchase and install. Certainly you’ll save money every month because you’ll be getting more heat out of the fuel you’re paying for. But if you don’t use your furnace all that much, the savings really won’t be that substantial.

Don’t forget that a furnace with an 80% AFUE rating is still quite energy efficient. And once you get up that high, you have to use your furnace a lot for the difference between 80% and 90% to really become apparent. So if you don’t use your furnace heavily during the winter, it will take you many, many years to make up for the higher purchase price of the 90+% AFUE models.

Pacific Beach Heating Tip: Components of a Heat Pump

Wednesday, January 4th, 2012

As every Pacific Beach heating contractor knows, because of their simply designed function – pumping heat one way or the other – heat pumps have relatively few components. However, these components do not work the way you might expect, if you are picturing, for example, a fan that blows heat in or out.

A heat pump operates on the same principle as an air conditioner or refrigerator, which may seem complicated at first, but it’s not. The heat pump consists of five main functional components, which are outlined below:

  1. The coils absorb heat from the surrounding air and channel it in or out of the home. There are two different types of coils in a heat pump. Condenser coils are outside the home transferring heat to and from the outside air. Evaporator coils are the reverse, transferring heat to and from the air inside the home.
  2. The coils are filled with a refrigerant, which is the medium that carries heat into or out of the home. On a cold day, for example, when the heat pump is in heating mode, the refrigerant in the condenser coils will absorb heat from the outside air, the flow inward into the evaporator coils, warming the interior of the house.
  3. The compressor pressurizes the refrigerant so that it is able to readily absorb as much heat from the air as possible. This is how your heat pump is able to gather warm air from the chilly outdoors to keep your Pacific Beach home warm.
  4. The reversing valve is the component that changes the flow of the refrigerant when switching from heating mode to cooling mode, or vice versa.
  5. Finally, the air handler is the fan component that distributed the heat throughout the house via your home’s ductwork.

While these are the five main components, there are several smaller parts involved within and alongside each of these, as well. You need not concern yourself with them, since you won’t have occasion to interact with them. A Pacific Beach contractor will be able to identify and repair any of the components of a heat pump as needed.

In addition to these five primary components, most heat pumps also include a heater pack, which is a bunch of actual heating elements for use when the heat pump cannot operate on its own. For example, you would turn on the “Emergency Heat” setting of your heat pump after a power outage to warm the refrigerant before use. That setting is supported by the heater pack.

How to Clean the Parts of a Heat Pump? A Question from El Cajon

Wednesday, November 9th, 2011

It is very important to keep your heat pump clean. It improves efficiency, helps performance and prevents malfunctions. Cleaning your heat pump should be part of your El Cajon home’s maintenance routine in order to keep the house as comfortable and worry-free as possible.

That is all well and good, but how do you go about cleaning the components of your heat pump. It’s one thing to advise you to clean, clean, clean…but it doesn’t do much good if you do not know how. To correct that, here are some tips to help you clean the different parts of your heat pump.

Caution: before doing any maintenance on your heat pump, including cleaning, be sure to turn off the power to the unit. This is a necessary safety measure.

Filters

  • If you use disposal air filters in your heat pump, skip this part. Just make sure to change them regularly, in accordance with the manufacturer’s instructions.
  • To clean air filters, follow the directions of the manufacturer that were included with the filter. This is also a good time to double check that the filters are installed properly.
  • Clean or replace your filters monthly during heavy use seasons, such as the warm summer months and cold months of late fall and winter.

Coils

  • Remove any debris from the outside of the coils and the surrounding area. Sticks and leaves may have accumulated near the outdoor coils, so just brush them away.
  • Using a soft brush attachment, vacuum the exterior of the coils. Take care not to bend or dent the coils.
  • Using a hose with a spray attachment, flush the coils with water from the inside out. This will remove any stubborn debris. Take care not to spray any electrical components, such as the fan or any nearby wires.
  • While you are inside the unit, vacuum the bottom inside to get rid of any more stray debris.

With that done, put everything back, replace the grille covers and power the heat pump back on. It should run smoothly with a fresh filter and no debris to gum up the works. Clean the coils every few months to keep the heat pump in tip top shape.

How Do I Check for a Dirty Evaporator Coil? A Question From El Cajon

Wednesday, September 21st, 2011

The evaporator coil is an essential piece of your El Cajon home’s air conditioning system. It absorbs heat from air that passes over it, and that air then travels into your home to cool it. So if your coil is dirty or isn’t functioning properly, the cooling power of your air conditioning system is diminished. Fortunately, this problem is fixed easily by cleaning the evaporator coil. You can do this on your own or have a professional come in to take care of it.

Signs of a Dirty Evaporator Coil

The most obvious sign of a dirty evaporator coil is an overall drop in system pressure. As long as you know what constitutes a normal pressure for your system, you should be able to tell if the current pressure is below that level. If it is, a dirty evaporator coil is probably your culprit. You can also check the static pressure in your system to see if that is low, but this requires specialized equipment.

Even if you don’t notice any particular signs that your air conditioning system isn’t working properly, it’s a good idea to clean your evaporator coils once a year or so. This can help prevent any larger problems from developing in the future.

Finding Your Coil

Probably the hardest part of cleaning an evaporator coil is reaching it. Unlike your condenser coil, which is located in your outdoor condenser unit, the evaporator coil is found inside near the air handler or furnace. If you have the owner’s manual, there should be detailed instructions telling you where the coil is and how to safely access it.

Alternately, you can have an HVAC technician show you what to do the next time they come out to work on your system. Whatever you do, though, make sure that power to your AC unit is completely shut off before you start working on it. Once you’ve gained access to the coil, use a brush or vacuum attachment to remove any debris or sediment you find there.

The Importance of Maintenance

Cleaning your evaporator coil is only one part of the regular maintenance required to keep your air conditioning system in good working order for the foreseeable future. There are plenty of things you can do on your own, but it pays to have a professional come out once a year or so to check out the entire system and make any necessary repairs.

How Do I Find the Right Size Unit for My Room? A Question From Bonsall

Wednesday, September 7th, 2011

When buying an air conditioner in Bonsall, there are a lot of things you need to take into account. One of the most important is the size and power of the unit you choose. Air conditioners come in many different sizes, so if you really want to get the most out of your purchase, you need to do your research and pick one that fits your home like a glove.

Square Feet and BTUs

The best way to determine how large of an air conditioner you need is to match the number of BTUs the unit has to the square footage of the room you want to use it in. That means you need to know what room you’re buying it for before you make your purchase.

The number of BTUs needed goes up proportionately with the room size, so even if you don’t have exact measurements or if your room is oddly shaped, you can get a good idea of how large an air conditioner you need. For instance, a 400 to 550 square foot room is best served by an air conditioner with between 8,000 and 11,000 BTUs, while a room that’s only 250 square feet would probably be fine with a 6,000 BTU unit.

Bigger Isn’t Always Better

One of the most common mistakes people make when buying an air conditioner is to assume that the bigger the unit the better it will work. The truth is that buying an air conditioner that’s too big for your room is just as much of a waste as buying one that’s too small.

A larger air conditioner will cost more, and it will probably make the room too cold. It will also cycle on and off more frequently than a properly sized unit and it won’t be able to properly control the humidity level, leaving you with a cold, damp environment. That’s not very comfortable.

Other Factors

The square footage is definitely the most important piece of data you’ll need before buying a new air conditioner for any room in your house. But don’t forget to take some other factors into account as well. For instance, if the room has particularly high ceilings or receives a lot of direct sunlight, you’ll probably need a slightly more powerful unit than the straight square footage would indicate.

If you’re not sure how certain features of your home will impact your buying decision, call a professional who can help you get a more exact idea of what it will take to stay cool.

Does Humid Air Affect How AC Runs? A Question From Tierrasanta

Friday, August 26th, 2011

You’ve probably heard a dozen times that humidity is removed by air conditioning. Unfortunately, the common assumption is that there is no inherent cost in allowing humidity to persist in their Tierrasanta home. But, did you know it costs significantly more to remove humidity from the air with air conditioning than with a dehumidifier? Here’s why.

Water Vapor in Your Air Conditioner

Consider the amount of energy it takes to raise the temperature of water by one degree – one BTU. However, to change water from liquid to steam, another 10 BTUs are required. So, imagine how much energy it takes to condense water vapor from the air (in the form of humidity) into a liquid. This is what your air conditioner does whenever it processes humid air. It takes about 1,050 BTUs to condense one pound of moisture in the air into liquid.

The cost of running your air conditioner strictly for dehumidification can be huge, especially considering the fact that humidity is heaviest in the morning and evening when you probably don’t need your air conditioner every day (at least not early and late in the summer). Imagine, the cost difference if you used a dehumidifier to remove 150 or more pounds of moisture per week and an air conditioner when needed just to remove 15-20.

Negative Impact on How it Runs

Another thing to consider is that humidity can actually put an extra burden on your air conditioner. While the system is designed to remove that liquid from the air and get rid of it through the cooling coil and condensate drain, every extra minute the system is running is a bigger burden on it. Of course it will do its job for a few years, but the extra running time will add up, not only on your electricity bill but eventually on the machine itself.

The added pressure will result in eventual breakdown of the system and a need for early replacement. The easiest solution is to purchase a dehumidifier. These run at a fraction of the energy level of a full AC system and work extremely well to remove humidity from your home. In fact, most air conditioners will only remove humidity after 20-30 minutes of continuous operation. For short cooling cycles, you may not even dehumidify the house. So a dehumidifier ensures higher levels of comfort all at a lower cost.

How to Use AC Most Efficiently in Fallbrook

Friday, August 19th, 2011

Air conditioning is definitely something most of us wouldn’t want to try and get through the summer in Fallbrook without. And for a lot of people, because of medical or other conditions, it’s an absolute necessity. But just because you need to run your AC unit all summer doesn’t mean you need to suffer under the weight of astronomical cooling costs.

So if you’re interested in ways to save on cooling without sacrificing comfort, here are a few tips to get you started:

  • Get a Programmable Thermostat – When you come home at the end of a long day, you want your home to be cool and comfortable. But if you only have a basic thermostat, you would have to leave your air conditioning on all day in order to make this possible. Paying to cool an empty house is probably the last thing you want to do. But what is the alternative?

    Programmable thermostats offer the best solution in a case like this. These devices can be easily integrated into just about any home air conditioning system and they allow you to set different temperatures for different times of the day. That means you can have your air conditioning off while you’re not home and set it to come on a half hour or so before you get there. This way, you get the pleasure of walking into a cool, comfortable house without paying extra to keep it that way when you’re not home.
  • Incorporate Passive Cooling – The design of your home and how you use it can also have an effect on how hard your air conditioning system needs to work. Taking steps as simple as closing the blinds to block out the afternoon sun, putting up awnings and making sure that the exterior of your home is painted a lighter color to reflect sunlight rather than a darker one that will absorb it are all excellent ways to reduce the load on your air conditioner.
  • Supplement Your System – You can also take a good chunk out of your cooling bills by using things like ceiling fans in conjunction with your air conditioner. A ceiling fan can effectively lower the indoor temperature several degrees on its own, allowing you to set your thermostat a little higher.

Air conditioning is a major expense that most of us are resigned to paying, but there’s no reason to pay more than necessary with so many strategies available to save money.
