How to Improve Air Quality in Your Home

While air pollution is often thought of as an outdoor issue, we spend most of our time indoors, so it’s important to pay attention to the air quality inside your home. The air inside your home may be polluted with formaldehyde, dust, radon, fire-retardants and other chemicals that may be used in cleaning products, as well as pollutants that are tracked in from outside. Dust mites, mold and pet dander are also common allergens found in the home.

Children, the elderly and individuals with chronic health conditions may be especially sensitive to indoor pollutants, but healthy adults may begin to see the effects of poor indoor air quality after prolonged exposure. These conditions can include severe allergies, respiratory conditions and other illnesses.

Fortunately, a few maintenance tasks and lifestyle changes are enough to reduce contaminants and correct indoor air quality issues. Find out how to improve your indoor air quality and ensure that you and your family are breathing the freshest, cleanest air possible.

Keep Your Floors Clean

Chemicals and allergens can accumulate in dust for long periods of time, but a vacuum with a HEPA filter can help you reduce these contaminants. HEPA filters also get rid of many allergens and toxins, such as chemicals, pollen, dust mites and pet dander. Be sure to vacuum high-traffic areas often, and don’t forget upholstered furniture, carpet edges and walls to get dust that has accumulated.

Mopping also picks up the dust that vacuuming misses. Plain water is enough to clean dust or allergens that are left behind, and microfiber mops capture more dirt and dust than conventional mops.

You should also invest in some high-traffic floor mats for each doorway into your home. This helps collect the dirt, chemicals and pollutants that may be tracked in on shoes, so all you have to do is clean the mat on a regular basis.

Maintain the Humidity Level

Dust mites and mold thrive in moist environments, so it’s important to keep the humidity in your home between 30 percent and 50 percent. A dehumidifier helps to reduce the moisture in your indoor air and control allergens and mold, and an exhaust fan or open window will keep moisture at bay.

You should empty the drip pans in your dehumidifier or air conditioner on a regular basis as well, since this only evaporates and recycles the dirty moisture back into the air.

Stop Smoking

Cigarette smoke is a big contributor to poor indoor air quality. Cigarette smoke contains over 4,000 chemicals that may increase the risk of asthma, respiratory infections, cancer and heart problems. Make your home a nonsmoking space, and if you or a family member smokes, commit to quitting to improve the air quality.

Test for Radon

Radon can be an issue in both new and old homes. This odorless, colorless gas significantly increases the risk of lung cancer due to its radioactivity from the natural decay of radium in soil. Radon is a problem in homes with cracks and holes in the foundation, but it can occur in any home.

Testing for radon is quick and inexpensive. If you determine that you have a radon issue, the Environmental Protection Agency offers a guide to reducing radon in your home.

Use Natural Products

Though you may enjoy the synthetic fragrances found in cleaning supplies, laundry detergent and air fresheners, these products dump plenty of chemicals into the air that may affect air quality. Most fragrances are derived from petroleum products and haven’t been thoroughly tested to check for adverse health effects in humans upon inhalation.

There are a few ways you can protect your home and your family from these chemical pollutants:

  • Use fragrance-free or naturally scented cleaning products.
  • Use mild cleansers that don’t use synthetic scents.
  • Avoid aerosol sprays.
  • If you’re using a scented product, open your windows to allow the chemicals to escape.
  • Keep rooms ventilated with a filtered air-conditioning system.
  • Use sliced lemons and baking sode to clean your kitchen and leave that lemon scent.
  • Keep live plants in your home, which act as natural air purifiers.

Have Your Ducts Cleaned

Air ducts are responsible for distributing hot and cool air throughout your home and maintaining a comfortable temperature. Ducts that are improperly installed or dirty are a possible source of pollutants and particle contamination that affect indoor air quality, however. If your HVAC system has been operating for some time without a duct cleaning, it could be circulating dust, odors and other contaminants around your home.

A professional duct cleaning can reduce the potential for mold growth and eliminate odors in your home from the dirt that accumulates. On top of that, duct cleaning also extends the life of your system and ensures optimal performance.

Consider Indoor Air Quality Products

Many consumers are paying more attention to indoor air quality and its impact on health and wellness. There’s a variety of indoor air quality products on the market to combat common indoor pollutants, such as:

  • Electrostatic filters.
  • Electronic filters.
  • UV antibacterial lights.
  • In-duct odor eliminators.
  • Whole-home humidifiers.

These products offer indoor air quality solutions to suit different home types and needs. Speak with an HVAC professional to learn more about the air quality options that are suitable for your home.

Getting the Most Out of Your AC System, Follow These Steps

Summertime is upon us. That means it’s time to rely on the AC system for the summer months to make sure your house stays comfortable throughout the summer. One thing you shouldn’t do though is just turn on the AC system and go. There are a few steps to take to make certain that your AC system will work at full strength for the summer season.

So what exactly are these steps? What should you do to protect your system and cool your home this summer? Learn eleven important steps to take so that you get the most out of your AC system and stay cool during the summer season.

Check Your Thermostat

Step one is to check your thermostat and be sure you are happy with the settings. If you only have one temperature setting, it is probably an outdated unit and you should consider upgrading to a more energy efficient version.

Check Your Ductwork

Go over your ductwork, especially exposed ductwork, and look for signs of wear, cracks, holes and the like, which can lower the AC efficiency in the home, or could result in cooling loss.

Check Your Air Vents

Walk around your house and look at the air vents in your ceilings, floor boards, or wherever you have them. Remove items that might block airflow, and vacuum the dust out of them if needed.

Check Your Drain Line

Usually mounted near your unit, you’ll find a drain pipe or piece of PVC. Check this for cracks or leaks and depending on condition flush the line if warranted to keep the line clear.

Change Your Filter

If you haven’t changed your filter recently, now is the time to do it. You should be changing your filter every three months (at the changing of the seasons is a good way to remember to do it).

Check Circuits

Make sure all your electrical connections are on. Unless you’ve de-activated them, they probably are, but always check nevertheless.

Be Sure Your A/C Unit is Turned on

You’d be surprised how many problems with air conditioning come down to the unit being turned off. Just check that the power switch is on.

Head Outdoors to Inspect the Unit

Check your AC unit to be sure there’s no blockage in or around it. Remove leaves, vines and debris as well as check for missing panels that protect electrical connections.

Check Coolant Lines

Make sure your coolant lines look good and call in the pros if any repairs look like they are needed.

Check the Wiring

Never touch live wires, but inspect them for damage or wear. If you see such damage, call a professional for service.

Should I Use a Swamp Cooler and an Air Conditioner to Cool My House

When you live in a desert climate, keeping your home cool can be an uphill battle. Fortunately, in the quest to make your home as comfortable as possible, you have a lot of tools at your disposal, including air conditioners and swamp coolers.

While both of these systems can help you control the temperature in your home, they function very differently, leading some homeowners to wonder if they can use both at the same time. Find out if you can use a swamp cooler and an air conditioner to cool your home and learn how each of these convenient tools functions.

How Swamp Coolers Work

Swamp coolers, which are also known as evaporative coolers, are a type of open cooling system that work best in climates with low humidity levels and certain hotter temperatures. Essentially, swamp coolers work by taking in warm, dry air, cooling it by passing it over a wet pad, and then directing the now cool air into your home.

Swamp coolers can cool the air in your home to a surprising degree and in some cases can be much more affordable than central air conditioners. However, on days with high humidity and or on days with temperatures into the 100s, the effectiveness of swamp coolers diminishes very quickly.

How to Use a Swamp Cooler

The first step in using a swamp cooler is to determine the kind you need. Window-mounted room coolers and whole-home coolers are available that can be mounted either on your roof or the ground. Roof mounted are the most efficient but are the toughest to install. Ground-mounted are the most popular.

Get a cooler that can handle up to 40 air changes per hour, with an average of 30, and 1000 CFM per air conditioning ton (referring to the BTUs of heat removed per hour). Purchase one with a solid air filter to remove allergens and particulates.

When using your swamp cooler, be sure the dew point is under 55 degrees Fahrenheit. Open a window to let the air out in rooms you want to cool — you’ll need up to 2 square feet of open window per 1,000 cfm to balance out the operation. Close windows in rooms you don’t want cooled. Choose the right speed to keep your home comfortable. A higher speed will cool more and a lower speed will be more energy efficient.

Basics of Air Conditioners

Most homeowners choose traditional air conditioners to cool the air in their home. Air conditioners, in very simplistic terms, essentially pulls warm air through the system and separates heat and moisture from that air leaving cold air which is then blown back into the house through the air ducts. The excess heat and moisture captured by an air conditioner is then released outside of the home. As you might imagine, this results in the air in your home being much cooler and drier.

Air conditioners are the most effective solution for controlling the temperature in your entire house and are generally unaffected by outside temperatures and humidity. A central A/C unit properly connected to your home’s ductwork can quickly transmit cold air through your home, keeping everyone cool and comfortable.

Can You Use Swamp Coolers and A/C Together?

Now that you know how both cooling devices work, you probably want to know if you can use a swamp cooler and an air conditioner together. Unfortunately, the answer is not effectively. These tools cool your home using diametrically opposed methods. Where a swamp cooler introduces moist air into your home, an air conditioner removes moisture, meaning they often cancel each other out when used at the same time.

To cool your home effectively, you should choose to only use one of these devices at time and not together at the same time.

Help Installing an Air Conditioner

Since you should not use a swamp cooler and an air conditioner together, to keep your home cooling cost down, you should think about installing or upgrading to a high-quality energy efficient A/C unit in your home with the help of the experts at Legacy Air.

Legacy Air provides both commercial and residential cooling services, and we would be happy to help you install an air conditioning system that will easily keep your home cool. Contact us right away to get started.

3 Reasons You Shouldn’t Delay Your Air Conditioning Tune Up

If you’re like most homeowners, you want to make sure that your equipment is in tip-top shape, and this includes your air conditioner. Your air conditioner is the machine that is most responsible for your family’s comfort. If you want to keep your A/C unit up and running, you need to be sure that you are scheduling annual tune-ups.

For those that live busy lives, find the time to schedule an A/C tune-up can seem impossible. However, this is a maintenance task that should never be delayed, for a variety of reasons. Here are some reasons that you shouldn’t delay your air conditioning tune-up and advice for keeping your A/C system running with professional help.

Detect Developing Problems

Although there are countless reasons that delaying an air conditioning tune-up is a bad idea, the most important to consider is the ability to detect small problems with your unit before they get out of hand.

Fixing a problem with your air conditioner early on can save you a large amount of money, especially if the problem would result in a major repair if ignored. During your tune-up, your A/C technician will fully inspect your air conditioner, allowing them to detect and correct developing problems before they become serious.

Save Money by Optimizing Performance

When it comes to air conditioners, most homeowners assume that they either work or they don’t, with nothing in between. However, it’s entirely possible that your A/C can be functional but not working at its optimal capacity, which can end up costing you more money than you might think.

If the performance of your air conditioner dips, it can result in much higher energy bills than normal. By delaying your tune-up, you’ll be preventing your air conditioner from functioning as efficiently as possible. On the other hand, after your tune-up, your air conditioner’s performance should be optimized, helping you save on energy costs.

Stay More Comfortable

As mentioned in the previous section, not scheduling a tune-up means your air conditioner may not be able to perform as well as it should. In addition to raising your monthly energy bills, this can also result in your home being far less comfortable.

When the temperature rises in the summer, your air conditioner will need to work extra hard to keep your home cool, and if there’s something affecting its performance, it won’t be able to keep your home comfortable in the way that you deserve. Scheduling a tune-up is the best way to guarantee that your home will always be at your perfect temperature.

Schedule an Air Conditioning Tune-Up

As you can clearly see, delaying an air conditioning tune-up is almost always a bad idea, especially if you want to keep your A/C unit up and running. If you’re ready to schedule a tune-up for your air conditioner, then you should get in touch with the team at Legacy Air.

One of your professionals can quickly examine your air conditioner and professionally correct any issues that may be preventing it from performing optimally. With us on your side, keeping your home comfortable will be easy. Contact Legacy Air today to request an appointment.

What Is Your Old AC Unit Really Costing You?

An AC unit really is a vital part of modern life. We count on our AC units to get us through the worst of the blistering summer. A good AC unit can last for 20 or more years. More often than not, the strategy of most homeowners is to run the unit until it dies and then replace it.

Legacy Air would like for you to take a minute and think about what keeping your old AC unit running is really costing you? Here’s a hint: it’s a lot more than just your monthly electric bill.

Can We Talk About Your Utility Bill?

Modern AC units are marvels of efficiency. Part of that is due to legislation in the 1970s and 1980s that demanded a better energy efficiency in appliances. But, the other part is that AC technology continues to improve over time.

If you’re running an older AC unit, you probably aren’t even coming close to a modern efficiency. While you’re worrying about the cost of a new AC unit, that poor cooling efficiency is resulting in utility bills that are twice as high as they should be.

That’s right: installing a new AC unit can slice your cooling costs by almost half in some cases. Wouldn’t it be nice to save some money every month? You can cool down your utility bill along with your house!

Older Models Need More Costly Repairs

That’s correct: older AC units need more costly repairs, and those repairs will end up being more costly. It doesn’t take a rocket scientist to know that the older your AC system is, the more likely it is going to need some kind of repair work. By the time you have the repair technicians come out and make those costly repairs, you could have already bought yourself a new AC unit.

Buying a new AC unit is like buying a new car. You know it’s going to be in top-notch condition for a while, so you don’t have to worry about repairs. Since the unit is new, it’s also going to have a factory warranty in case something does happen.

Legacy Air wants to remind you that you think you’re saving money by keeping your old unit and making repairs, but, in reality, all that repair money would probably pay most of the cost of a new unit. Who wouldn’t want to save hundreds of dollars in repair costs?

Your Health Is Really Important

Older air conditioners make people sick. When air is not moving around your house like it should, and the air that is circulating isn’t being filtered very well, you have a recipe for disaster. Upper respiratory infections, severe allergic reactions, and even colds and flu can really take over a living space with an older AC unit.

It goes without saying that the more your health suffers, the more healthcare costs you’re going to see. Medical care isn’t cheap. New AC units have better filtration technology so that you stay healthy and the doctors get less of your hard-earned money. Breathe easier; stay healthy!

Legacy Air wants you to know that that old AC unit of yours may be eating up cash that you haven’t even thought of. An older AC unit can raise your utility bills, eat up cash in the form of repair bills, and make you sick. Replacing an old unit with a new AC unit (with an advanced filtration system) can put money in your pocket.

Repair or Replace: What to Do When Your AC Unit Stops Working

It is every homeowner’s worst nightmare. You’re sitting inside on a hot summer day, getting a nice reprieve from the heat thanks to your home air conditioner, when all of a sudden your AC unit stops working—and you are trapped in a sweltering, hot box.

While no one ever wants to find themselves in this scenario, it is a situation that can happen to virtually anyone with an AC unit, at any time. So, when your AC unit stops working, what should you do? Pay to have it repaired? Or replace it all together?

Unfortunately, there is no black and white answer to this common, and often annoying, dilemma.

While repairing usually costs less upfront, it typically doesn’t mean this is the best solution. Repairs often aren’t guaranteed, and spending a few hundred dollars in the moment for a repair, doesn’t mean you won’t have to cough up more money in the future.

So, Should I Replace My Broken AC Unit or Repair It?

When it comes to deciding whether or not you should repair or replace your unit, you need to look at your individual system to determine the best approach, not only in the moment, but in the future as well. These are the factors that will help you decide.

The Age of the AC Unit

Age is one of the most important factors to consider when deciding whether you should repair or replace your air conditioning unit. According to the Department of Energy, the average lifespan of an air conditioning unit is between 15-20 years.

If your AC unit is more than 10 years old, you should consider replacing your unit with a more efficient version.

Newer styles may cost more money, but they will be more efficient than your previous model and can save you money on a monthly basis when your energy bills come,

R-22 Refrigerant

Some air conditioning units require additional refrigerant. This is a sign of a coolant leak. However, not all refrigerants are the same. Most newer models have R-410a refrigerant, which is considered a more environmentally-friendly alternative for AC refrigerant. However, older models have what is known as R-22 refrigerant, which has become much more expensive as it gets phased out.

If your system needs a R-22 refrigerant, known as Freon, it can cost anywhere from $40-$175 more per pound, in addition to labor costs. This can add an extra $1,000 to your HVAC repairs.

R-22 refrigerant will not be legally available after 2020.  In most cases, a unit that requires R-22 and has a refrigerant leak, should be replaced, not repaired.

Energy Efficiency

If your energy bills keep going up, but the rates from your electric company are staying the same, then it might be time to repair your AC instead of replacing it. You can do the math yourself or use the Energy Star Home Energy Yardstick Tool to determine how efficient your home is.

Replacing an old AC unit, with a new energy efficient model may cost you more up front, but if you are planning on living in your home for 7-10 more years, the savings from your new unit can more than make up for the costs.

While according to HomeAdvisor, the average energy efficient central air conditioning unit will cost between $3,730-$7,154, according to EnergyStar, that unit can save you between 20-40 percent on home cooling costs.

The Cost of Repairs

When it comes to making HVAC decisions, cost is almost always at the forefront of every customers mind. Of course, one of the biggest factors in deciding between repairing and replacing the system all comes down to dollars and cents.

A good rule of thumb is, if you are going to be spending the next 10 years in your home, then you should replace your AC unit, if you are spending less than 10 years, it may be more cost-effective to repair.

The average lifespan of an AC unit is about 10-15 years. But remember, if the air conditioner is more than 15 years old, it is time to replace it. But, if you are on the edge about the financial commitment, you can do a little math to make the decision for yourself.

So, How Much is This All Going to Cost?

According to HomeAdvisor, the average cost the repair an AC Unit in the United States is $336. The typical range is between $163-$520 while the high end of repairs can be as high as $1100.

Certain types of repairs will also cost more than your average fix. For example, replacing a home air compressor can cost between $1350-$1800 while replacing an evaporator coil can be anywhere from $650-$1200.

Applying the $5,000 Rule

So, you know the cost of replacing your unit and the cost of repairs. How do you make the right decision?

Many HVAC technicians will apply the $5,000 rule to making this call. Simply multiply the repair costs by the age of the unit.

For example:

If your repairs are $500 and your unit is 5 years old, your total would = $2,500. In this case, it would make sense to repair your system.

If your repairs at $900 and your unit is 10 years old, your total would = $9,000. In this case, it would make sense to replace your system.

Finding a Professional for Your HVAC System

No homeowner ever wants to make the difficult decision between repairing or replacing their system. While there is no way to guarantee your HVAC system will ever need to be repaired, or replaced, there are things that you can do to lessen your chances of having to make this decision. This includes finding a professional you can trust for your HVAC needs.

Regular maintenance should be done on your HVAC system every year. According to, the average cost of this annual maintenance is only between $100-$150 and it can help you spot small issues before they turn into big problems and make sure your HVAC system has everything it needs to run properly.

While all of the aforementioned guidelines are a good foundation for understanding of your HVAC system, the decision to repair or replace can be complicated. Every situation, and every system, is different. A professional HVAC technician can not only help you with things like regular maintenance, but with making the difficult decision on whether to repair or replace your system.

The team of professionals at Legacy Air can give you an informed opinion on the matter and helping you understand the costs and benefits associated with repairing or replacing your AC unit.

The Origins of Air Conditioning – The History of the Air Conditioner

Although Willis Haviland Carrier created the first version of the modern day air conditioner, methods of artificially creating cool air existed long before he was born.

To keep cool ancient Egyptians would dangle reeds in their windows and had a system where water would drip down the reeds.  As the wind blew across the reeds the water would evaporated and create cool air. You might recognize that this is the same concept behind today’s swamp coolers. Ancient Rome had a system of circulating cool aqueduct water behind the walls of the “Elites” houses. One Roman in particular, Emperor Elagabalus, would send slaves to the mountains to gather snow to lay in his personal gardens. Persians used wind towers and cisterns as ancient air conditioners.

In truth Mr. Carrier himself developed the air conditioner not to keep cool, but rather to help relieve the air of its moisture in his muggy printing office. Carrier later recognized the commercial value of his invention and created the first mass production of Air Conditioners.

While some of the richest Americans experienced air conditioning in their homes and high dollar hotels, for most Americans their first introduction to AC came via movie theatres. Las Vegas’ own El Portal theatre (still around today as an Indian and jewelry shop located downtown) became the first commercial building to have air conditioning
