Common Types of Air Cleaning Devices for Fallbrook Homes

Monday, January 30th, 2012

In recent years, you’ve likely heard dozens of warnings in Fallbrook from newscasters, community publications and local contractors about the dangers of indoor pollutants. That’s a good thing – the air in your home, if left untreated, can be a significant health risk to you and your family. But, how do you choose an air cleaner that will get the job done? Let’s take a closer look at the options currently available and what each of them has to offer.

Air Filters

Air filters are the simplest form of air cleaning. They are designed to capture particles that stay airborne long enough to reach the filter. They don’t work well to capture all large particles, however, because they tend to settle before they reach the filter device. Proper air flow is necessary to supplement the process and remove more pollutants.

High efficiency filters with an MERV rating of 14 or higher are recommended, though HEPA filters (which have an MERV of 17-20) are preferred for their ability to capture particles as small as 0.3 microns. In-duct particle removal is a good upgrade as well because it filters moving air and captures more particles.

Gas Phase Filters

These filters are designed to capture gases produced by building materials, household electronics, paint, and your combustion appliances. They are not always effective for long, so filters must be checked and changed frequently. These systems are not frequently used in home systems, but if you have particular pollutants, they may provide a number of clear benefits.

UVGI and PCO Cleaners

These cleaners are designed to kill pollutants like bacteria and mold. They are usually installed in the ductwork or air cleaner and while the effectiveness of either has yet to be properly measured there is a growing trend to include them in systems where homes experience a large number of allergic reactions or asthma symptoms.

Ozone Generators

There are still some systems that produce ozone as they circulate air back and attract it to a filter for removal. The results are mixed and ozone itself can be a significant irritant to the lungs, so it’s unclear whether these actually work very well.

Which Is Best?

It really depends on the pollutants you’re trying to remove. The best course of action is to have your indoor air tested and then discuss with a contractor the best combination of technologies to remove pollutants from your indoor air.

When Should You Replace Instead of Repair Your Heating? A Question from La Jolla

Wednesday, November 30th, 2011

We all dread an expensive repair in La Jolla, whether it is a car that needs a new transmission, a leaky roof that needs new shingles, or electrical wiring that has been chewed up by a wild animal. We often try and put bandages on things that we know should be replaced but we just can’t afford to replace them.

The same can be said about your home’s heating system. When your heat goes out or your home just doesn’t seem to be heating up to the setting on your thermostat, your first inclination is to check and see if it is running. Some people will put their hand over a heating vent to check for hot air while others may go into the basement or mechanical room to listen to hear if the furnace is running. Maybe there is a blockage in the ventilation system or a blown circuit breaker, two relatively easy fixes.

If the furnace isn’t working after checking the obvious symptoms, your next move is to call for service. Any qualified heating professional would be able to diagnose your problem and offer suggested repairs. Something relatively minor like a bad circuit board or blown fan motor are not real expensive repairs and are the best option versus replacing the furnace. And you may keep experiencing the same problem and getting the same repair work done – anything to avoid an expensive replacement.

But at some point the vicious cycle will come to an end. Your repair bills will begin to inch their way past the cost of replacing the furnace. You can only bandage a problem so long before it becomes “unfixable.” You may not want to pay an expensive replacement bill but consider the alternatives.

First is the obvious – it costs too much to keep repairing the furnace. Secondly, you never know when the furnace may break down and its failure to operate could have dangerous effects on the people in your home, especially if someone is sick. Third, your furnace may not be able to keep up with the heating demand due to lifestyle changes, i.e. an addition put on the house, carpeting removed and wood floors exposed, a new window, door, or skylight added, etc. Your old furnace may not have been designed to keep up with these changes and the repairs are only delaying the inevitable.

Ask yourself if everyone in your home is comfortable during cold weather. If most answer no, it may be time to consider replacing that old furnace with a new, energy efficient model that uses today’s technology – and leaves a smaller carbon footprint – to keep up with the demand for heat, in any sized building or home. Your decision to replace your old heating system could be as simple as the need to use modern technology to solve your indoor comfort problems.

Sources of Carbon Monoxide: A Guide from La Jolla

Wednesday, October 26th, 2011

The risks of carbon monoxide have been well documented for years, and everyone in La Jolla knows how dangerous it can be. It can be fatal at high concentrations, but even in low levels it can be poisonous enough to make you sick.

What you may not know is that there are many sources of carbon monoxide, also known as CO. This poisonous gas is formed by any incomplete combustion process. Since combustion is not 100% efficient, that means carbon monoxide is released any time something burns.

To be more specific, here are some examples of carbon monoxide sources you might encounter around your house:

  • A furnace or chimney can leak exhaust gases, including CO, into the home if it has been improperly sealed or vented. For example, if the chimney has a small crack in the flue that goes unnoticed, CO from the fireplace can be vented back into the house.
  • A furnace supplied by an under-sized gas line will often burn the gas at a sub-optimum temperature. The result is incomplete combustion of the gas, which means a source of CO.
  • Old, dilapidated or poorly maintained heating systems are a big culprit. Often the seals or fittings are loose on these units, causing CO to leak out of them and into your house. Or they may not burn fuel as efficiently as they used to, so carbon monoxide is more readily released.
  • Using machinery, like a propane generator or a gas-powered saw, in a poorly vented garage can be very dangerous. Sometimes people don’t think about this one because the garage is large enough that it seems to be ventilated better than it is.
  • There’s a reason that barbeque grills are labeled for outdoor use only: they release a lot of carbon monoxide. Both charcoal and propane grills should only be used outdoors, and you should avoid the smoke from charcoal in particular as much as possible.
  • Smoking tobacco releases carbon monoxide into the air, along with other potentially dangerous gases.

There are plenty of other sources, as well, but those are some common ones. To protect yourself and your family, make sure any areas where combustion occurs are well-ventilated, keep your HVAC equipment well-maintained and in good repair and invest in a home CO detector. They are inexpensive, and many are combined with a smoke detector, so you only need to buy one unit.

What Happens if You Put Your Air Filter in the Wrong Way? A Question From Carlsbad

Wednesday, October 12th, 2011

Air filters are important pieces in your overall Carlsbad home’s comfort system. They keep unwanted debris and sediment out of your indoor air and they help your system run smoothly for years to come. However, if you’re not careful, an air filter put in backwards can lead to quite a few problems with your heating and cooling system.

The Most Common Problems

The most common problem you will face with a backwards facing filter is simple inefficiency. If your furnace is forced to blow air through the non-porous end of a filter, it will take more energy to do so. The blower will be overworked and you will pay more money for your heating. The same is doubly true for an air conditioner which has multiple filters in place to keep outdoor contaminants out of your indoor air.

Beyond the cost of improper filtering, you will likely suffer from a decrease in indoor air quality. The filter is designed to remove a lot of unwanted debris, but only when installed in a certain direction. If you set your filter up backwards, the normally collective end of the device will not face the air supply. In effect, your filter will help keep debris in the air.

This results in a clogged filter and improperly cleaned air when it reaches your lungs. If you have a home indoor air quality system it will help to supplement this problem for a while, but the clog will eventually become too much for your system.

Avoiding the Problem

There are two ways to avoid improper installation. First, you can have a professional install the system for you. Whenever you need a new filter ask someone to come and take care of it. When they do, though, pay close attention to how they set the filter and any other steps they take. By carefully watching you can ideally learn what it takes to do this step yourself and hopefully keep your system running smoothly for years to come.

Variety of Ways to Cool Your Temecula Home Naturally

Friday, September 9th, 2011

It is normal these days to simply switch on the air conditioning when the temperature begins to rise outside in Temecula. But this can get expensive quickly, so it is a good idea to look into some alternative cooling methods as well. Fortunately, there are actually some great ways to help keep your home cool without touching that air conditioning at all. You will probably still want to have it around for extreme circumstances, but the less you need to use it, the more you will save in the long run.

Using fans, ceiling fans in particular, can certainly help to keep you cool on many moderate summer days. But they are far from the only options available. In fact, the design and composition of your house itself will have a lot to do with how easy it is to keep it cool all summer long.

One of the main reasons that your house gets so hot inside during the summer is that sunlight heats the air inside when it hits the walls, roof and windows. Closing your blinds will help to keep some of this out, but there will still be plenty of heat from the sun working to increase the indoor temperature.

What you really want to do to keep your house from heating up because of sunlight is to actively reflect the sun’s rays away from your home. You can do this by having light colored roofing and exterior paint or siding put on. While the dark colors typically used for this type of work absorb the vast majority of the sunlight that hits them, lighter colors will reflect it away.

This works well for the walls, but on your roof it can be a bit more difficult to stop the absorption of heat from the sun because of the nature of typical roofing materials. What you can do, however, is add a reflective coating like white latex on the roof. This will dramatically reduce the amount of heat that is able to come into your home in this way.

Also, natural shade can do a lot to keep sunlight from getting to your home to begin with. Planting trees close enough to your home that they will block out the sun but far enough away that they have room to grow will eventually help to keep your home much cooler without any extra work whatsoever. If you have more questions about the best ways to keep your house cool, contact your local HVAC contractor.

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.

How to Stay Affordably Cool This Summer

Monday, July 25th, 2011

Putting in a high quality, energy efficient air conditioning system is a great step to take when you are trying to keep your house cool and comfortable all summer without paying a fortune in cooling costs. Many of the latest air conditioners are able to use very little energy to provide powerful cooling power to your house no matter how big it is.

But if you are really serious about keeping cool and keeping costs down, there are plenty of other things you can do to give your air conditioning system a hand. It might seem silly, but putting in a little bit of effort around the house can save you quite a bit in the long run.

For instance, since you are paying to keep the air in your house cool, it is a good idea to make sure that the air you are cooling stays in your house. Sealing off unused doors and windows with plastic is an excellent precaution to take to ensure that no cooled air leaks out through the cracks and door jambs. Also, you will want to check for any other openings that could create a draft and allow cool air to escape or warm air to get in.

However, just letting in air from outside in the summer is not the only way that the heat can get in. The sun is powerful in the summer and the more you can block of it, the cooler your house will be. So make sure that your blinds are closed to block out the sun, particularly in the afternoon. Morning sun is not nearly as powerful as the sun you get towards the middle and later part of the day.

All of these steps will help to take the pressure off of your air conditioning system and allow it to get its job done with a minimum of energy expended. And that will certainly save you money every month. You can save even more, though, by adjusting the temperature on your thermostat a bit as well.

Most air conditioning systems are set to a default temperature of 72°F. While this is probably quite comfortable for you, it is likely that you would be equally as comfortable at 75°F. In fact, you probably will not even notice the difference. But that small adjustment can actually save you quite a bit on your monthly cooling bills.

Why Install a Bathroom Ventilation Fan?

Monday, July 11th, 2011

Your bathroom is one of the dampest rooms in your house. Without proper ventilation, you put it at risk of developing mold and mildew which can then spread and enter your home’s air supply. But, what kind of ventilation fan is best and how will it help you remove those unwanted allergens?

Choosing a Ventilation Fan

Step one is to find a ventilation fan that will remove excess humidity and moisture from your bathroom. When you take a shower, wash your face or run a bath, not only do you fill the room with a lot of water, you heat it up. With nowhere to go, that heat lingers and everything from tiles to wood fixtures will absorb the moisture. Over time, it leads to mold and mildew growth – some of it damaging to your bathroom, and much of it damaging to your health.

A ventilation fan must be efficient in removing the excess humidity in your bathroom and pushing it outside. But, that ventilation fan shouldn’t make your bathroom too cold or waste a great deal of the heating or cooling energy you pay so much for.

The best solution then is to get a fan that either connects to a central exhaust system to remove the humidity and air from your bathroom or use an energy recovery ventilator to keep the warm or cool air where it belongs. These systems will remove only the stale air filled with humidity and allergens.

Integrating with the Rest of Your Home

You can have a simple bathroom fan placed in your home that just blows air out of the room. This is effective and will reduce the risk of things like mold and mildew, but it’s costly to operate due to energy loss and it doesn’t integrate with the rest of your home well.

That’s why a good fan should be part of a larger exhaust and ventilation system. The type you need depends largely on the overall humidity of your home and your annual heating and cooling costs, but generally, a simple system that exchanges heat before air leaves your home will do the trick.

Most modern homes have bathroom ventilation already installed. If yours does not, take a closer look at the options currently available. You’ll find different sizes, types and brands designed to fit your particular needs. Whatever you choose, simple ventilation can do wonders for a previously damp and mildew filled bathroom.

How Do I Find the Right Size Unit for My Room?

Wednesday, June 15th, 2011

When buying an air conditioner, 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.

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

Friday, May 27th, 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.
