Maybe you’ve invited a service technician to your home before (yes, we do think of this as “invited” because we’re glad to be chosen by you). But once he got there, you started hearing clicks and clanks and simple expressions like, “Hmmm.” So you start wondering, “What in the world is he doing?”

Well, I can sympathize. It isn’t fun to have a stranger in your home sort of doing his own thing, as if you don’t need to be involved. That’s why our techs explain what they’re going to do, and then when they’re done, explain what they did. It takes the mystery out of maintenance. It reassures you about what’s taking place on a very important piece of equipment in your home.

Maintenance involves specific steps, particular to the equipment. In fact, we can tell you now what kinds of things are going to take place to save you energy, convenience and comfort. To learn more, take a look at this free report, Simple Math: How Routine Maintenance Adds Up to Be Well Worth Your While.

Up for a quick survey question? Here goes: what time of day would you most like to experience problems with your air conditioning system?

Would that be the middle of the night when you can’t sleep due to the heat? Or maybe the first thing the next morning when you’re dressing for work? Or mid-afternoon when things are getting really toasty warm?

Go ahead – just pick your favorite time when you would most like to experience the reality of an air conditioning repair… Uh, I’m guessing you’re looking for the slot for “none of the above.”

Actually, I don’t have to conduct a survey to figure out that no one likes to be inconvenienced at any time by cooling problems. But I can tell you this: we provide 24-hour service because we know that you can’t always schedule problems at a convenient time. So call us when you need us!

Do you ever feel like you’re scaring people? Let’s say when you visit a home, you sense that the family that invited you would like you to go through a security clearance before entering. Well, that could make the social gathering a little awkward. And yet, I’m sympathetic because I know a little about what that’s like – from both sides.

In this business, contractors sometimes get painted with a broad brush. A couple of fly-by-night operations swoop in, make promises, cash checks and leave town with work undone – and others who really do want to help feel the cloud of suspicion. It happens. So let me share a helpful piece of advice: “Trust, but verify.”

That’s a phrase Ronald Reagan made famous when he was talking about the old Soviet Union. Basically, it means to proceed confidently but with a backing of verification. Calling about home comfort services may not be on the same level as the signing of treaties with communist countries, but please feel free to verify our promises. And you can look for that type of verification in our guarantees, long work history in this community, testimonials of satisfied customers… and in many other ways. So let us hear from you when you need us!

Here's one of my all-time favorite phrases: I'll deal with that later. Actually, I misplaced my sarcasm font or I would have used it just then. But a lot of people I know really do like that phrase.

Sort of like deferred maintenance. This is a concept known by businesses and institutions with the property, buildings, and equipment that basically means, We don't have the budget to repair what's declining as it is declining, so we'll deal with it later. It's easy to sympathize with the approach of waiting until something is broken until calling for a repair. But it can also be a costly approach.

Homeownership isn't really any different. We have to keep an eye on the systems and infrastructure that keep our home running. Your air conditioning system, obviously, is in this equation.

By investing each year in routine maintenance, you can save long term on the cost of repairs, extend the life of your equipment and avoid inconvenient breakdowns. It's simple logic, and only takes a little bit of planning, which means, dare I say? dealing with it now. But that doesn't have to be scary. Read, Make Plans for Air Conditioning Maintenance for quick tips to maintaining your system.

You’re probably familiar with the concept of “cause and effect” and how it can lead to a whole bunch of trouble. (Not that I speak from experience. And not that I don’t!) But this basically means that some things happen not just on their own but as part of a set of events.

As an example, let’s say you’re walking into your home when your phone starts ringing. To answer your call, you quickly drop your high-priced prescription sunglasses on the couch. You sense that’s not a good idea, but you tell yourself you’ll pick them up when you finish the call. Then you forget. Can you imagine what “effect” is coming? Yes, someone, maybe even you, will probably be sitting on those glasses in the near future.

See the point (even if through crushed lenses)?

Now let me apply it to something more in my area. If the air inside your home is making respiratory issues like allergies and asthma worse, there could be several causes that are leading to these effects – and several strategies that can help your family breathe a little easier. A few of them are here in this report called, “Improving the Quality of Your Home’s Indoor Air.” Take a look.

One good thing about the end of springtime is the end of spring allergies. And now we have summertime, where the breathing’s easy… achoo!

Ah, yes, summertime sneezes. That can be quite a bit for all of your family’s noses to handle. And why is this happening, you ask?

Most folks think that spring allergies are worse than summer, thanks to pollen and new growth in lawns and gardens. But summertime also has active allergy issues, especially when staying cool means spending long periods of time inside tightly closed homes.

Indoor air can trap all sorts of pollutants that make respiratory issues worse and set off sneezing. Quite a number of our customers have had significant trouble with allergies and asthma, and we help them out by identifying the trouble spots we detect in the air in their home.

If you’d like to know more about what could be lurking in your indoor air, check out this free report, “Identifying Asthma and Allergy Triggers in Your Home.”

How about a quick language test? Ever hear of the terms SEER and EER? Well, if it’s near dinnertime, you might think that SEER sounds like something you do to a steak, and EER sounds like corn just off the stalk. So maybe I’m just hungry, but I’m not talking dinner – I’m talking comfort.

And therein lies the problem. If you don’t share a common language, it’s hard to understand what someone is trying to tell you.

This concept is true in all sorts of ways – whether it’s English vs. French, or text message acronyms vs. correct spelling in complete sentences, or industry terms vs. what words people actually understand.

All industries seem to have an “insider language,” where words and technical terms are thrown around as if they should make sense to everybody. Sometimes they do, sometimes they don’t.

We see that often as our customers are trying to choose the most energy-efficient solutions for their home, but sometimes they feel like things are lost in translation. If that could be you, you might appreciate this brief report on, “The Language of Energy Efficiency.” Take a look.

Are you the sort of person who says, “I may be indecisive, I’m not sure.” If given the choice between “Yes, No or Maybe,” do you look for the check-box that says, “All of the above?” You have my sympathies…

Making decisions is no laughing matter, and homeowners are faced with a slew of them. Some are smallish, like selecting new towels for the guest bathroom. Some are a little larger, like choosing a new bed for the guest bedroom. Some are even larger – like figuring out how to avoid in-law house guests once they find out about your new towels and bedroom set!

And believe it or not, some decisions get even more sizeable than that – like whether or not to replace a home comfort system. Well, if you’re in the “fact-collecting” mode for that last one, we’ve got some information that can help.

With the summer we’re having in the Phoenix area, your air conditioning unit is experiencing a heavy load. But is it up for the job? Take a look at this free report, “Repair or Replace? How Do You Know?”

Save a little money here, save a little money there, and pretty soon it adds up, right? Well, one of the areas where we most like to see our customers save money is in your energy use.

When the days are very hot, your air conditioning can account for up to 70% of your utility bill. So it makes sense that whatever you can do to improve energy efficiency at home can help you keep more money in your own pocketbook (and send less to your utilities).

But the important point to make here is that you don’t have to take big steps to save energy. You can take small steps over time or make a few small changes in your habits. And you’ll find a lot of ideas for doing just that at the link below.

If you’d like to learn more about how you can keep more energy dollars for yourself while enjoying more comfort at home, we’ve got a free report with 10 good tips on how to “Save Energy. Stay Comfortably Cool.”

How about taking a moment to reflect on one of my most favorite, most fun words in the whole world: maintenance. Well, maybe it doesn’t sound like a “fun” word to you, like it does to me.

So why all the excitement? Well, I get excited about lower energy bills and fewer repairs – both of which are the results of maintaining your home comfort system. Not making sense yet? Think of it this way…

Maintaining your car keeps it in its best condition. Maintaining a healthy lifestyle keeps you in your best condition. Maintaining a steady income provides for what you need. No matter how you look at it, maintenance is the best bet for good results.

And your home comfort system isn’t any different if you want it to perform at its highest efficiency for your best comfort. If you’d like to know more about how maintenance helps and what it involves, take a look at this free report, “The Perks of a Well-Maintained Air Conditioner.”

Most systems have a lifetime of 10 to 20 years. As your equipment gets older, it's efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it's age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.

No. Replacing only the outdoor unit will lower the efficiency of the unit. In fact, you can lose up to 15% of the unit's efficiency! Even worse, your system may fail sooner than normal and most manufacturers' warranties will be voided. You should always replace the indoor cooling coil with the outdoor unit.

No, you don't want your air conditioner to be too big. Air conditioners control the comfort level in your home by cooling the air and by removing humidity. An oversized air conditioner will cool your home faster, but it will use more energy and will not remove humidity adequately.

A unit that is too big for your home will have short run cycles. It may take only a short time to cool the air, but the unit shuts off before enough air blows across the indoor coil where moisture condenses into water and drains from your system. Too much moisture left in the air can lead to mold and mildew problems.

These short run cycles also mean your system starts and stops more often which uses more energy and causes a lot of wear and tear. An air conditioner operates more efficiently during long run cycles.

The same holds true with heating systems. An oversized furnace will warm the house quicker, but it uses more fuel and causes greater temperature swings in the home.

A matched system is important for a variety of reasons. One is comfort. When all your components are properly sized to your home, you can control exactly how much heating or cooling you need so you can relax. Also, a properly sized matched system enables every component to perform as designed, meaning proper cycle times are maintained, humidity is controlled, and system sound is minimized.

Another reason matched systems are important is efficiency. Most systems people buy are too large for their homes, which uses more energy than needed for your home. A matched system outlined by a dealer who has completed a load calculation for your home provides just the right amount of heating and cooling you need so you get the most value for your utility dollar.

At the risk of telling you something you're tired of hearing, replace the air filter in your furnace on a regular basis. Dirty air filters reduce the amount of air flowing through a system and make the furnace work harder to maintain the temperature. How often you change the filter depends on the type of filter you use, if you have pets, and the size of your equipment. Please give us a call and we can give you proper guidance.

Proper air filtration is just as important to the health of your heating and cooling system as it is to the health of your family. Without proper filtration, dust and dirt can build up on your system which impacts operation and efficiency. A high-efficiency filter will remove more dust, dirt, pollen, mold, and other particles from the air. If you suffer from allergies or other respiratory problems, you should strongly consider a high-efficiency filter. No matter what type of filter you have, make sure you change it regularly.

Yes. Keeping your system properly maintained will lower energy and repair costs, prevent breakdowns, and prolong the life of your equipment. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

Without warranty coverage, a breakdown can mean significant expense in parts, labor, or both. However, with one of our service agreements, you avoid that unexpected significant expense. While no warranty can guard against every possible problem, we can explain the broad range of protection our service agreements afford.

With a high efficiency air cleaner, you can remove up to 99% of the pollen and spores that find their way into the home. There is also a great reduction in household dust, dirt, smoke, and other air pollutants. Your indoor air will become cleaner and fresher while reducing the allergens and dust that circulate throughout the house. With a whole house humidifier, you can relieve the irritating discomfort of dry indoor air. The humidifier reduces itchy skin, scratchy throats, static electricity, and damage to your furnishings and woodwork. Since humid air feels warmer than dry air, you do not have to set the thermostat as high to feel the comfort you want. A lower thermostat setting will reduce the costs of your energy bill.

Molds are part of the natural environment. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees, but indoors, mold growth should be avoided. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on surfaces that are wet. There are many types of mold, and none of them will grow without water or moisture. Click here to learn more about mold prevention in your home from the EPA.

When humid air passes over chilled cooling coils, water condenses and drips through the coils into a collection pan, from which it continuously drains. Problems with these systems may occur when this water collects and becomes stagnant when it becomes blocked, either on the coils or in the drip pan. The pan will grow mold that can infect your home with dangerous mold spores very quickly. Problems also exist when the HVAC ducting contains microscopic mold spores that stay continually present and blow contaminants around the home or office often caused by mold in other parts of your home.

You can do 3 things to prevent mold growth in your system:

1. Preventative maintenance will ensure that the collection pan under the indoor coil stays clean and clog free.
2. Install ultra violet lights next to the cooling coils to kill any mold or bacteria growing on the coils or collection pan.
3. Keep your ductwork clean and use a high-efficiency filtration system to keep your entire HVAC system clean.

SEER, AFUE and HSPF are all measures of energy efficiency. Air conditioners may look similar, but their Seasonal Energy Efficiency Rating (SEER) can vary widely. Higher SEER numbers save more money spent on electricity. A 13 SEER air conditioner, the EPA "current minimum standard", uses 23% less energy than a 10 SEER unit (EPA standard up until Jan. 2006). Even though 13 SEER is the minimum efficiency available, we currently offer a line of air conditioners that start at 13 SEER and go all the way up to a 21 SEER . Depending on your average usage, higher SEER air conditioners can significantly reduce your electric bill.

Heat pumps have SEER ratings like air conditioners and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher HSPF ratings mean greater energy savings. The HSPF scale range is 7.5 to 13.0.

Today's new high-efficiency furnaces can save up to 50% in operating costs over a ten-year-old furnace. Many 1990 and earlier model furnaces have Annual Fuel Utilization Efficiency (AFUE) ratings of 65% or less. The minimum AFUE rated furnace that can be sold in the United States as of May 1, 2013 is 80% in southern states and 90% in northern states.

Our current product offering starts at this minimum AFUE rating and goes all the way to a very efficient 98.3% AFUE rating. Depending on your average usage, higher AFUE rated furnaces can significantly reduce your gas bill.

Cooling

• Upgrade to a high-efficiency air conditioner - Swapping your old, inefficient air conditioning system for a high-efficient one can cut electricity bills by one-third. Consult one of our professional technicians to ensure your system is the right size for your home, and you aren't over- or under-cooling for your space needs.
• Turn up the temperature — To save electricity during the summer, set the temperature above 75° as every degree below this will add an extra three to five percent to your energy bill.
• Install ceiling fans — Change the direction of airflow on your ceiling fans. In the summer, the blades should operate in a counter-clockwise direction as a way of creating a nice, gentle wind.
• Have an annual maintenance performed — Having an annual maintenance performed on your air conditioner by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.
• Don't block vents in well-used rooms — Keep your supply and return air vents free of objects like blinds, carpets or furniture so your air conditioner can operate efficiently and there is even cool air distribution.

Heating

• Upgrade to a high-efficiency furnace — New high-efficiency furnaces use up to 50% less fuel than an older system. It can save you up to 25 percent of your home-heating costs in one year, and within a few years, you'll have recovered the initial cost of replacing/upgrading your furnace. Choosing a model with an energy efficient motor can save 20 to 50 percent of the energy needed to continuously operate a fan motor. Let us show you the advantages of replacing your old furnace today.
• Have an annual maintenance performed — Having an annual maintenance performed on your furnace by a licensed technician will help ensure it operates at its peak efficiency and catches any potential breakdowns before they occur.
• Install a programmable thermostat — A programmable thermostat enables you to control your home's temperature when you're away or asleep. For every 1° you lower your thermostat for seven hours per day, you save one percent on your heating bill.
• Don't block vents in well-used rooms — Keep your supply and return air vents free of objects like blinds, carpets or furniture so your furnace can operate efficiently and there is even heat distribution.
• Install ceiling fans — Change the direction of airflow on your ceiling fans. In the winter, the blades should operate in a clockwise direction helping to push the warm air from the ceiling down into the room.

The average home spends about $1,900 annually on energy bills. Heating and cooling accounts for as much as half of a home's energy use. The EPA provides important recommendations for energy-efficient equipment, including proper sizing, quality installation and maintenance, and other home improvement considerations to help you get the most out of the heating and cooling products you purchase, save energy, and save as much as 20% annually on your total energy costs.

ENERGY STAR qualified products prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE).

Heat pumps are a great solution for your home comfort system because they work to provide both heating and cooling. Heat pumps have SEER ratings like air conditioners and Heating Seasonal Performance Factor (HSPF) ratings for measuring heating efficiency. Higher SEER and HSPF ratings mean greater energy savings.

Heat pumps are a very efficient alternative to electric heat. A heat pump works the same as an air conditioner in the summer, but it runs in reverse in the winter to heat your home. The system will be matched with a backup heating source, most often electric heat for those extremely cold days of winter.

With a traditional heating and cooling system, if you wanted to save more, you had to use less. But a Hybrid Heat system combines the benefits of intelligent control for both gas and electric heating to create an intuitive system that can actually react to changing conditions.

No matter what the temperature is outside, a Hybrid Heat system will automatically select the fuel source most efficient for your home, which means you'll stay warm in the winter, cool in the summer and save money all year long.

To design a Hybrid Heat system for your home, we professionally match one of our heat pump units with a natural gas furnace. Contact us to see how much energy you can save over your existing system.

Variable speed fans operate on a simple principle: they are able to spin at different speeds depending on the heating and cooling needs of your home. Usually, they operate at lower speeds, delivering a steady, reliable stream of warm or cool air to your home. This helps control humidity levels, utility costs and system noise. When conditions become more extreme, the fan speed increases so that the system can meet increased demand, guaranteeing that on even the hottest days or coldest nights, you're comfort needs will be met.

2-stage cooling is a method of cooling that can better manage the cooling of your home while outdoor temperatures are changing. It can also better maximize indoor comfort and energy efficiency. 2-stage cooling systems are typically the most energy efficient systems out there.

2-stage cooling can be done by having one unit with two compressors, one small and one large. The small one is typically capable of putting out about 50% the capacity of the larger one. The second way to have 2-stage cooling is to have a single scroll unloading compressor. This compressor can unload its capacity down to about 66% of maximum capacity. Both these methods of getting 2-stage cooling allow the unit to run at a lower stage when the high stage is not needed. By doing this, energy is saved.

2-stage heating has the same principle as 2-stage cooling. It allows the unit to adjust itself based on the amount of heating that is necessary. 2-stage heating is a good way to save on heating costs.

A heat pump system would have two different sized compressors, a small and a large one. The compressor that is used at a given time would depend upon the need. If only a small amount of heating is necessary, the smaller compressor would be used to save energy. The large compressor would only be used when a large amount of heating was needed.

A gas furnace that is 2-stage has a modulating gas valve that regulates gas flow depending upon the need.

Normal cooling settings are 75 degrees - 80 degrees. Normal heating settings are 68 degrees - 72 degrees. You should always set your thermostat to the highest possible setting that is comfortable for you in the summer, and the lowest comfortable setting in the winter. Setting your thermostat in this way will maximize your energy savings. On average, every 1 degree of temperature change is equal to about 1% energy savings. For example, changing your thermostat setting from 75 degrees to 76 degrees in the summer could result in savings on your cooling costs.

This can occur for many reasons; uneven solar heat load through windows, an undersized system, improperly balanced or clogged system or a single system serving a two-story home with no zoning control. Each situation is different, usually requiring an onsite analysis with problem specific recommendations. Please call to arrange for us to see your home.

Yes. As of January 2010 the refrigerant R-22 (what consumers call Freon®) is no longer allowed to be used in the manufacturing of new equipment. R-22 has been used as the "standard" refrigerant for many years but has been found to be harmful to our planet by our government. All new air conditioners and heat pumps use R-410A, the more "environmentally sound" refrigerant.

R-22 is still the most commonly used refrigerant in existing air conditioning equipment in residential homes today. However, per the Montreal Protocol, caps have been established to eliminate the production of R-22. In 2004, there was a 35% reduction; in 2010 there was a 65% reduction; in 2015 a 90% reduction; and finally in 2020 a 99.5% reduction in the production of R-22. This means that during the time of these reductions with high demand, the price of each pound of R-22 refrigerant could potentially skyrocket.

If you are considering replacing your existing air conditioning equipment, most higher efficiency products have already made the switch to R-410A, the more "environmentally sound" refrigerant.

A difference of 6 decibels (such as between 72 dB and 78 dB) is technically a four-fold increase in compressor sound when rating air conditioners or heat pump units. However, it takes a difference of 10 decibels to double the loudness. It is also noted that it takes approximately 3 decibels for the average human ear to discern any difference in loudness at all.

Great strides have been made in reducing the operating sound level of equipment. We will be happy to show you the difference in sound ratings with our product line.

Yes. Each year, carbon monoxide kills more than 200 Americans and sends nearly 5,000 more to emergency rooms for treatment, reports the U.S. Consumer Product Safety Commission (CPSC). Where does it come from? When carbon-based fuels such as gas, oil, kerosene or wood burn, they produce gases. When fuel combustion or burning isn't complete, carbon monoxide enters the air. The CPSC advises that carbon monoxide detectors are the only way to alert yourself to the presence of toxic gas in your home. If you wake in the night with a headache -- and especially if another member of the family complains of a headache or is difficult to arouse -- get out of the house fast and seek medical help. We recommend carbon monoxide detectors be installed in your home!

Propane (LP) gas: You have this type if your gas comes from a tank located outside close to your house. Propane is stored as a liquid under pressure in tanks and cylinders. In most residential applications, propane is used as a vapor. When liquid propane changes into a gas vapor, it expands in volume. This means that even a small leak of liquid propane can result in a much larger quantity of propane vapor, which can be especially dangerous in a confined space. A chemical odorant has been added to propane to give it a distinct smell. Learn to identify this odor. Propane gas is heavier than air, so it will sink to the floor and spread. To check for the presence of propane, carefully smell all over a room, especially in low spots.

If you smell propane (LP) gas:

• Exit your home immediately.
• Propane gas can ignite easily. Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
• From a safe area, contact your propane supplier and call 911.
• If you are able, shut the propane gas supply off at the tank.
• Stay away from your home until you've been told that it is safe to return.

Natural gas: You have this type if you have a gas meter and pay a natural gas supplier or utility. A chemical odorant has been added to natural gas to give it a distinct smell. Learn to identify this odor.

If you smell natural gas:

• Exit your home immediately.
• Do not light a match, start an engine, use a cell phone, or do anything that may create a spark.
• From a safe area, contact your gas company or call 911.
• If you are able, turn the gas off at the meter.
• Stay away from your home until you've been told that it is safe to return.
