Money Saving Tips in Del Mar: Heat Your Crawl Space

Monday, April 30th, 2012

If you’re like most people in Del Mar, you probably focus on how to keep the living areas of your home warm and comfortable in the winter months. Of course, you want to do this with as little expense as possible and so installing heating systems and insulation in all of the rooms of your home naturally makes sense. The main goal of this is to eliminate any areas where heat might be able to escape, thereby causing you to spend more and run your heating system for longer to keep the temperature indoors at an acceptable level.

What you might not often think about, however, is the fact that the crawlspace under your floors is probably not insulted at all. Of course you and your family don’t spend much time there, but if you’re trying to keep your home comfortable for as small a price tag as possible, this is something you should think about addressing.

There are actually several reasons that heating and insulating your crawlspace can save you money in the long run. For one thing, the ducts and pipes that carry your heated air and water to various locations throughout your house generally run right through these very crawl spaces. Even with an average amount of insulation surrounding those pipes and ducts, you’ll still be losing heat to the outdoors as the air and water travel through the crawl space.

Of course, pumping heat directly into the crawl space would be a waste too, since there is no insulation to keep it there. With the proper amount of insulation, however, you can easily heat your crawl space with very little energy and potentially save a ton in the long run.

When your ducts and pipes are traveling through a heated space, they’ll retain the heat they started with and bring that to the rest of your home. You’ll pay very little to keep the crawl space warm and you’ll save a lot by conserving the heat and hot water that you do generate to keep your house comfortable.

Plus, because your crawl space is generally located directly underneath the floor, you’ll be protecting the actual rooms of your home from heat loss as well. And you floors won’t be so cold to walk on either. Overall, there really is no reason not to take the time and have your crawl space properly insulated and heated.

How to Use a Heat Pump Reversing Valve in Pacific Beach

Monday, April 16th, 2012

As conventional energy resources dwindle and become more expensive, alternatives increase in popularity.  Heat pumps in Pacific Beach, like the natural heat they harness, are fast rising to the surface.

Tapping the stored energy of the greatest solar collector in existence, ground source heat pumps (GSHPs) are electrically powered systems that tap the earth’s relatively constant temperature to provide cooling, hot water, and heating for Pacific Beach homes and commercial buildings. Simple, efficient and abundant, heat pumps are best used in moderate to hot climates where the differential of temperatures is not extreme.

In General

Functioning on the same principle as refrigerators, the heat pump uses a liquid to absorb heat as it turns into a gas and release heat as it returns to a liquid state. During the summer, the heat pump operates as a standard central air conditioner, removing heat from the house and venting it to the outside.

In the winter, the heat pump reverses this process, extracting heat from the cold air outside and releasing it inside the house. The heat pump is very efficient when the outside temperature is around 45 degrees Fahrenheit to 50 degrees Fahrenheit, but it becomes less efficient as the temperature drops.

The Heart of the Matter

The reversing valve in the heat pump switches the process from absorbing heat from the inside to evacuate outdoors like an air conditioner to extracting heat from cold temperatures outside and redistributing it indoors.  The thermal energy at play is the natural force of heat to move toward cooler temperatures, releasing energy in the shift.  Heat pumps take care of both and the reversing valve controls the direction of the flow.

The reversing valve has two states of operation: relaxed and energized.  In the relaxed state, the heat pump can be programmed to introduce either heated or cooled temperatures into the conditioned space, depending on the direction of the flow of refrigerant through the closed loop.

By applying a 24 volt charge of AC current (a low voltage typically used in HVAC systems), the valve becomes energized and reverses the flow, producing the opposite conditioning.  The reversing valve may be driven by the heat pump through the use of a control board or directly by a thermostat.

As energy resources rapidly change in cost and supply, heat pumps utilizing geothermal energy are looking like a viable alternative in today’s market.  Call Cal-West Air Conditioning to learn more about how heat pumps can be installed at your house.

Steps to Take Before Turning on Your Furnace in San Marcos

Monday, April 9th, 2012

You are feeling a chill in the air. The outside temperatures are going down each day and the nighttime temperatures are forcing you to break out the flannel pajamas, robes, and blankets. It’s getting cooler and you are holding off turning on your furnace in San Marcos for the first time of the season, maybe because you envision high utility bills or you are afraid of what you’ll hear, feel, or see coming from your furnace after several months of inactivity.

There’s not much you can do to control higher utility bills, they are like death and taxes. But there are some things you can do to take the “mechanical anxiety” out of turning on your furnace for the first time.

You can’t go back in time but you may want to consider “summerizing” your furnace after you shut it down in preparation for the cooling season – or during the cooling season. Have a qualified heating and cooling technician stop by for a quick furnace maintenance an inspection and cleaning.

A preseason inspection and cleaning will prevent some problems that may affect some of your senses later on. For example, a smell coming from your furnace may indicate a burning or smoldering electrical component. A noise may indicate a noisy fan or a loose belt, causing poor or no airflow. Touching your ventilation system and feeling for any vibration can indicate poor airflow. Visually checking your instruments like thermostats for verifying proper temperatures or a digital readout on our carbon monoxide alarm for any traces of harmful gas are also important to furnace start-up.

If something goes wrong, don’t blame it on your thermostat or the cold weather; blame it on a lack of preventive maintenance. Your best bet is to have a qualified service technician do a clean and inspection – to minimize any surprises at start-up and to keep you and the occupants of your home comfortable and safe while your furnace begins another season of hard work.  If you have any questions about this process please call Cal-West Air Conditioning

Furnace Control Boards for Temecula Homes

Wednesday, March 7th, 2012

One way to be a truly responsible Temecula homeowner is to familiarize yourself with the major systems and appliances in your home. By having at least some understanding of how, say, your refrigerator or toilet work, you gain understanding of how to use them efficiently and detect when something goes wrong.

The same is true of your furnace, which can appear to be a complicated piece of machinery. In order to help you get acquainted with your furnace, we will discuss one of its main control components, the furnace control board.

As the name suggests, furnace control boards are responsible for governing the operation of the furnace. At a minimum, a simple furnace control will control the furnace ignitor (e.g., a spark generator or glow coil), the gas valve and the furnace thermocouple, also called a flame sensor.

More complex furnace control boards will also have control over the blowers and/or the built-in diagnostic system.

To simplify things, you can think of the furnace control board as being a driver and the furnace as its car. Just as the driver oversees all the functions and operation of the car from ignition to shutting off the engine, likewise does the control board for the furnace.

A typical operation sequence for a furnace control board goes something like this:

1. The control board receives a signal from the thermostat that the temperature is too low.

2. It starts the ignition system, whether that be a spark generator, glow coil or pilot light.

3. Once the ignitor is hot, the furnace control board initiates the flow of gas through the burners, where it is ignited.

4. The control board keeps the furnace running until it is signaled by the thermostat that the temperature is now high enough, or until it detects something is wrong.

(An example of a malfunction where the control board would get involved is a thermocouple that is not detecting enough heat. In this case, the control board would shut off the gas flow to prevent a leak into the home.)

Furnace control boards are an essential part of your home’s HVAC system. And now, as a responsible homeowner, you know just how important.  If you have any questions please call Cal-West Air Conditioning.

How to Check if Your HVAC System is the Right Size in Pacific Beach

Tuesday, February 28th, 2012

Do you ever feel that your home just doesn’t get cool enough during the warm months or warm enough during the cold months in Pacific Beach? You have tried to adjust your thermostat to the right comfort level but it just never seems right. And on top of that, you notice that your utility bills keep going up and up. Even when you dial up the thermostat in the summer and dial it down in the winter to saving on energy usage, your bills are still about the same.

You could try adding fans and shedding clothes during the warm months or wearing sweaters and crawling under a pile of blankets in the cold months. But do you really enjoy living that way? There must be another solution as to why your heating and cooling (HVAC) system is just not keeping you comfortable – and affordable.

That air conditioning condensing unit sitting in your backyard and the furnace in your basement should be making your home as comfortable as possible. But in many cases, they are not.  That’s because whoever installed those HVAC system components didn’t do their homework on your home. The components were sized incorrectly. If a furnace or air conditioner is sized incorrectly, it usually cannot keep up with the demand for heat or cold and often puts such a burden on the equipment. As a result, regular failures and repair bills are commonplace.

And it may not be the fault of the installing HVAC contractor. Over the years your home may have undergone renovations including additions and new windows, which have increased the square footage or demand for more heating or cooling. Those renovations may not have included upgrades to your home’s HVAC system.

So how do you check for the right size? Call a professional HVAC contractor and ask for an energy audit for your home. The audit will include several key checks including a load calculation, which adds in the size of your home’s living space, number of door and windows where heat loss or gain could occur, and a check of heat loss or gain through leakage in cracks, roofs, crawlspaces, etc. An energy audit will determine what size of furnace or air conditioner is needed to meet the heating or cooling needs of your home and its own individual characteristics. Your HVAC contractor may also factor in the number of building occupants and normal usage patterns, i.e. having a home office or stay-at-home parent versus a working family where your home is occupied mostly at nights or on weekends.

All of these factors are considered when determining the equipment size. In air conditioning jargon, you will hear about tonnage of cooling capacity. An example may be a 2.5 ton air conditioning unit for a 2,000 square foot home. In furnace jargon, you will learn about Btu ratings, which are British thermal units. Most furnaces are sized in 20-25,000 Btu increments. Each is matched to the cooling or heating needs of your home. Your HVAC contractor will likely recommend using a programmable thermostat, too. That way, you can set the temperature of one or more zones in your home to when each zone is occupied.

Make sure you don’t hire someone who “guesstimates” how much cooling or heating capacity you need for your home. Find a qualified professional who will make the correct calculations and who will qualify their recommendations. A properly sized HVAC system will equate to manageable utility bills and above average indoor comfort. You can live with that.  Please call Cal-West Air Conditioning with any questions.

Troubleshooting Your Problematic Heat Pump in Carlsbad

Friday, February 10th, 2012

If your heat pump isn’t working properly in Carlsbad, there are a number of things that might be wrong. But, where do you start and how do you solve these problems quickly and inexpensively? Here are some tips for common heat pump problems.

Low Air Flow

Your heat pump is designed to provide steady air flow to the entire house. When it was originally installed, the technician sized it to do so. If it suddenly stops providing enough air flow to your entire house or if the air flow it provides isn’t as comfortable as you’re used to, something is probably wrong.

More specifically, there is likely an issue with the heat pump itself since the device will compensate for most external problems by running longer and harder. Some quick heating maintenance will often rule out serious problems, so you should have someone inspect your device as soon as you notice a problem.

Leaky Duct

If there is an external problem, such as leaky ductwork, it tends not to be as noticeable right away. Often, when ducts are leaking, air flow problems will occur only in certain rooms of your home. Even then, the heat pump might be able to maintain the right temperature in those rooms – you’ll just have a higher energy bill because of the energy loss in the ductwork.

The best way to determine what is happening and how best to tackle the problem is to have someone test your ductwork for leaks, a relatively quick process.

High Energy Bill

If your energy bill suddenly increases dramatically, it is usually due to energy loss somewhere in the transfer between the heat pump and the rooms of your home. Leaky ducts can be the culprit, but so too can the air handler or the heat pump itself. If you notice a sudden increase in your energy bill, look for other symptoms like uneven heating or cooling in certain parts of your home or noises coming from the ductwork or your air handler.

No matter what other symptoms accompany the increase, you probably need repairs. Your home may still be comfortable now, but the heat pump can only make up for the problem for so long and in the interim, it is being put under excessive stress that reduces its lifespan.  If you have any questions about heat pumps please call Cal West Air.

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.

Clairemont Mesa Heating Maintenance Guide: Downflow Gas Furnaces

Friday, January 27th, 2012

Proper care of your Clairemont Mesa home’s downflow gas furnace starts with proper installation and continues through routine cleaning and maintenance. But before you can even have a downflow gas furnace installed, you need to make sure it’s the right fit for your home.

Downflow gas furnaces are so named because of the direction that air flows through them. The cooler air is taken in at the top and directed downward, heating up as it travels, and then is expelled through the bottom of the furnace into ducts that feed the rest of the house. Because of this configuration, downflow  gas furnaces are typically installed in attics as opposed to basements.

If you have a basement and you’d rather install your furnace there, then an upflow furnace is probably the better choice for you. However, as many newer homes don’t have basements at all, downflow gas furnaces are growing in popularity and usefulness.

As with any other furnace, it’s important to have a downflow gas furnace professionally installed. This will ensure that the venting system is properly in place and that your house will be heated as effectively and efficiently as possible.

Of course, there are some other things you can do to help your furnace heat your home and keep your energy bills down. For instance, make sure you have proper insulation everywhere, particularly in the attic and crawlspaces where much of the normal heat loss in a home occurs.

You can also make your home more airtight in the winter by sealing up any unused windows and doors with plastic and making sure all storm windows are in place. Basically anyplace that a draft could develop, you could be losing heat and that costs you money. So to ensure that all of the money you’re spending to heat your house is actually going to that purpose, check periodically to make sure your home is still sealed up tight.

Also, just like any other type of furnace, a downflow gas furnace will require regular maintenance to make sure it continues to run efficiently and to replace any parts that may have worn out over time. Having a professional Clairemont Mesa technician come out once a year to carry out this type of service will wind up saving you a bunch of money and can help catch problems before they are able to get out of hand.

Carmel Valley Furnace Maintenance Guide

Monday, January 23rd, 2012

Depending on its frequency, there are different types of maintenance tasks associated with keeping your automobile in tip top shape. Did you also know there are tasks that can be performed at various intervals to keep your Carmel Valley home’s furnace in peak running condition? Well, there are.

For example, the most frequent maintenance task is checking the filters in your air handling unit. These are often called furnace filters but in reality, they serve the same function to filter air to and from your air conditioner, too. It might be easiest to just call them air filters. The frequency of replacing or cleaning air filters usually depends on the type of indoor environment you live in – like humidity levels, number of household pets or occupants, etc. In general, filter maintenance should occur every one to three months.

A less frequent maintenance task is cleaning the moving parts of the internal mechanism. You may only need to have your furnace cleaned every six months to a year, depending on its use. In some cases you can perform the cleaning yourself or it is included in an annual cleaning as part of a service agreement with a qualified heating and cooling contractor. A furnace can typically run at peak efficiency when it is cleaned on an annual basis.

You can also make it a regular habit of checking the motor bearings and fan belt, too. You can lubricate the bearings and tighten or replace the fan belt on a same schedule as cleaning the moving parts.

Other maintenance tasks related to your furnace, which may require longer interval times include ventilation system cleaning, or more commonly known as duct cleaning. Some homes don’t require this type of maintenance more than every five to ten years – perhaps longer. Unless there are unusually high levels of dust, allergens, or contaminants in the air, most ventilation systems can remain clean for several years.

Of course, you can turn all of your maintenance tasks over to a heating and cooling contractor – and have the most peace of mind.
