When Is It Time to Install a New 16 SEER Package Unit?

Friday, September 5th, 2014

If you own a business in Fresno, CA, air conditioning is crucial for maintaining a comfortable environment for your employees and/or customers and clients. A rooftop package unit, which combines all the components of the air conditioning into a single cabinet, is one of the best ways to condition your workplace.

However, no air conditioning system, packaged or otherwise, will last forever. At a certain point, you may discover that your current packaged AC can no longer do the work it is supposed to, or it has started to drain money due to an inefficient performance. When you think you need a replacement, call on the team at Shaw’s Air Conditioning. We’ll look over your current system and determine if repairs will do any good. If the system is too aged and worn down, we will tell you when it’s a better idea to have installation of a new unit with a higher efficiency rating.

We recently installed a new 16 SEER package unit for a Central Valley business. They called us to look at their current air conditioning system, which was very old and suffering from one of the major problems that occurs with age in an AC: Freon leaks. When refrigerant begins to leak from an air conditioner, it not only impairs the AC’s cooling power, but it will eventually damage other components, such as the compressor, leading to a complete breakdown.

In this case, we detected numerous leaks in the system. Although it was possible to fix them, the business owners opted instead to replace the decaying system with a new 16 SEER American Standard Package unit. This was definitely a wise choice, since the older system probably only had a few more years of service remaining to it, and it was already operating at lower efficiency and costing more to run than it should. With the new 16 SEER unit, the business would start saving money immediately thanks to the higher efficiency.

You should always seek the opinion of professionals when it comes to repairing or replacing air conditioning in Fresno, CA. The experienced technicians at Shaw’s Air Conditioning can help steer you to the choice that will do the most long-term good for your business or for your home.

What are the Benefits of Ductless Mini Split Systems?

Friday, July 11th, 2014

Although the phrase “ductless mini split system” may seem like a confusing term, it’s actually a fairly painless alternative to other air conditioning options. Ductless mini splits are air conditioning systems that don’t need ducts in order to cool your home. This may be a great solution for those who have had issues with their ductwork or want to save on their energy bills every month. Read on to find out whether ductless mini splits are the best option for your new air conditioning installation this summer.

No Ducts

Of course, the main distinction of a ductless system is that it does not use ducts. This may mean that you’ll have to make fewer service calls, especially if you’ve experienced a lot of issues with the ductwork in your home in the past. Sometimes, the ducts inside of a house have been installed improperly, causing airflow issues that may decrease performance and efficiency or repair issues with other parts of your AC. Ductless systems eliminate this possibility, which could mean fewer future repairs.

Zone Control

Ductless mini-split systems allow you to install multiple air handlers throughout your home, each of which can be controlled with its own individual thermostat. This is good news for your family members; they can adjust the temperature in their own rooms according to their own unique preferences. This keeps everybody happy, while also allowing you to heat or cool only the rooms in use. If no one is downstairs on a warm night, for example, you can always turn off the AC to prevent unnecessary energy loss.

Energy Savings

When you cool an entire home although only one or two rooms are occupied, you end up spending more on cooling costs than is necessary. The multiple thermostats involved in ductless systems can help you save energy, as can the lack of ductwork. With most central AC units, there is a high risk of air leaking through the ducts, which results in a lot of unnecessary energy loss. Ductless systems could significantly reduce the amount of money often spent on this type of issue.

Shaw’s Air Conditioning provides many heating and cooling options for your home, including ductless systems. For air conditioning services in Fresno, call us now!

How to Find the Best Air Conditioning Service

Friday, June 27th, 2014

When you search for air conditioning service in Fresno, you may find many contractors that claim to offer the best service at the lowest price. So how can you be sure you’ve found the best air conditioning service for your particular needs? With so many air conditioning businesses in the Central Valley, it can be difficult to find the right service for you. This list details some of the things you should look for when selecting a new AC contractor.

Read through the Website

Many contractors have websites that detail some of the services they offer and some information about the company. Make sure the company lists contact information and that your area is included in the listed service areas. It is also helpful if the air conditioning service providers list the various services they provide, so that you’ll be able to return to them whenever you need repair, maintenance, an upgrade or replacement. Even if you are only calling for a repair, you should make sure the company offers other services in case you need to call again in the future. Many AC companies even offer 24-hour emergency services.

Look for Recommendations and Reviews

When searching for a reputable AC service, you should always look at the recommendations and reviews of others. You might want to begin by asking your friends and neighbors about any successes they’ve had with professional air conditioning installation, maintenance, or repair. You can also check the company’s website or other sites where customers post ratings and reviews. You’re more likely to have a good experience with an AC company who has a history of positive feedback.

Ask for Quotes

When you call an AC service, ask if they can give you a quote or estimate for the service you need. You can always call several companies to compare prices. However, don’t sacrifice the quality of your repair service for lower prices. Make sure the contractor you choose offers both affordability and quality service.

Whether you need professional AC installation, repair, or maintenance, Shaw’s Air Conditioning is one of the best sources for Lemoore air conditioning services.

What Does SEER Stand For and Why Does It Matter?

Friday, May 23rd, 2014

You may have heard the term “SEER” spoken of in relation to air conditioning systems. It’s a very important term and it has a huge bearing on the type of air conditioner you purchase for your home. Quality services that install air conditioning in Fresno and other towns in the Central Valley can talk about specifics with you, but for now, all you need to ask yourself is “What does SEER stand for and why does it matter?”

The term stands for Seasonal Energy Efficiency Ratio, and it’s used to measure an air conditioner’s relative efficiency. The exact formula involves the BTUs (British Thermal Units) generated in the summer months, divided by the watts-hours consumed in the same period. That gives you a number typically somewhere between 7 and 24. The higher the number, the more efficient the air conditioner; that is, the more energy that goes directly into cooling your home instead of being wasted on faulty components and the like.

It’s fairly self-evident why that number would matter. The lower the number, the more energy your unit wastes. Older units sometimes have a SEER rating as low as 6, though units manufactured after January, 2006 need to have a rating of at least 13. That’s a very efficient number: 30% more efficient than the previous minimum SEER rating of 10, though not nearly as high as the most efficient units on the market. Naturally, units with a high SEER rating will cost more than those with a lower SEER rating, but they will make up for it with improved savings on monthly energy costs during the hot summer months.

When it comes to air conditioning in Fresno, efficiency can mean a difference of hundreds of dollars a month in cooling costs. That’s why the SEER number matters so much. For more information on what SEER stands for, or to schedule an installation contact the experts at Shaw’s Air Conditioning today.

3 Benefits to a Whole House Humidifier

Friday, May 9th, 2014

The dry heat of a California summer often means increased comfort: aridity draws heat from our bodies rapidly, helping to cool us off even during roasting weather. However, the dry climate does bring problems with it as well that can affect you and your home. If you suffer from problems due to low moisture in your house’s air, consider having professionals install a whole-house humidifier in your HVAC system.

Here are three benefits you’ll receive from a whole-house humidifier. These advantages go beyond what any portable room humidifier can deliver. But you’ll need to have expert technicians handle the work. Shaw’s Air Conditioning offers installation of humidifiers in Fresno, CA (and dehumidifiers as well). Contact us to find out about the options for balancing the humidity in your house.

Benefits of Whole-House Humidifiers

  • More comfort: Low humidity may help you feel better during intense heat, but when the weather cools, you’ll discover low humidity makes you feel worse during the cold. The moisture in your skin will easily escape into the dry air, taking body heat with it and making you feel chillier than the room’s temperature. Balanced humidity not only means you’ll feel more comfortable year-round, it also means translates to work for your heater during the fall and winter because you will feel warmer in general.
  • Improved health: Both high and low humidity can create health issues. In the case of aridity, a household can experience dry skin, respiratory infections, and an increase in flus and colds that transmit easier in dry weather. The arid conditions also contribute to the viability of some dangerous viruses. With balanced humidity, these viruses rapidly die out, and the other problems will also vanish. There’s a bonus as well: fewer shocks from static electricity, so you won’t have to feel wary about touching the doorknobs during the winter.
  • Less damage to furnishings and possessions: Low moisture is destructive for your home’s interior. It peels wallpaper and makes paint chip. Dryness also warps and causes wood to split, which will mean damage to your furniture, floors, and walls. (If you have antique furniture, you should invest in a humidifier now.) Musical instruments will suffer from aridity, as will other precision devices.

When you contact air quality specialists like those at Shaw’s Air Conditioning, technicians will analyze your home’s air and determine the type and size of humidifier you need for maximum comfort, health, and home protection. After installation, count on the technicians for the necessary maintenance and repairs to keep your humidifier running.

Shaw’s Air Conditioning offers many solutions for indoor air quality problems: whether its air filters, UV germicidal lights, duct repairs, dehumidifiers, or humidifiers in Fresno, CA we can take care of the work for you.

How Do AFUE Ratings Measure Heat Efficiency?

Monday, February 17th, 2014

Whether it’s your refrigerator or your furnace, we all want our appliances to function as efficiently as they can. This is especially the case with new appliances, which we expect to perform at a higher level than the old worn-out items they replace. With furnaces, a little expert advice can help yours. Here in Fresno, heating installation services can place new, more efficient furnace systems in your home with little fuss or grief. That efficiency is measured by the AFUE rating, which stands for annual fuel utilization efficiency.

How do AFUE ratings measure heat efficiency? The equation is actually quite simple.

All heaters require energy to function, just as they output energy that goes into heating your home. The AFUE ratio is simply the percentage of the energy taken into the unit that actually goes into heating the home. For example, say your heater consumes 50,000 BTUs (British Thermal Units) worth of energy every day and produces 40,000 BTUs worth of heat. That gives it an AFUE rating of 80% or 40,000/50,000. If the same heater produces 45,000 BTUs for heating, its AFUS rating would be 90% or 45,000/50,000. The remainder of that energy is lost to waste, inefficiency and problems of a similar nature.

It’s not hard to see why a furnace with a higher AFUE rating is preferable to one with a lower rating. A high AFUE rating means doing more with less energy and will pay dividends on your monthly bills. Older units tend to drop their AFUE rating after a while, as wear and tear take their toll. A newer unit should have a higher AFUE rating than the unit you’re replacing, though you should be prepared to pay a little more for such a unit. In any case, pay close attention to the AFUE rating on units you’re looking at. If you know how AFUE ratings measure heat efficiency, you’ve gone a long way towards being able to make an informed choice. Heating installation services like Shaw’s Air Conditioning can help you find the most efficient unit in your price range.

How Insulation Affects Heating Costs

Thursday, February 6th, 2014

When the time comes to save money on heating, homeowners naturally focus on the heater itself. Here in Fresno, heating repair services often take calls designed to upgrade or otherwise improve a heater’s efficiency, as well as installing newer and more efficient heaters to help homeowners save money on monthly costs. But there’s more to saving money on heating than just the heater. Your home itself plays into the equation, especially the amount of insulation you have in your attic and walls. Here’s how insulation helps heating costs.

Insulation works on the principle of slowing the transfer of heat. It’s made of material that heat passes through very slowly, keeping it in your home for longer than it might otherwise. In olden days, people would use straw or clay bricks as insulation. (There’s a reason why medieval villages used straw to build their rooftops.) Here in the 21st Century, we have much more efficient materials available, such as fiberglass and mineral wool. When placed in your walls, they slow down the escape of all the heat generated by your furnace. The more insulation you have, the better your home can do that.

The principle works just as well in the summer as in the winter, since the insulation keeps the heat outside from filtering into your home, and helps the cool air from your A/C unit stay comfortable. It’s best to look at your house as a bottle, holding in all of your conditioned air. Insulation acts like a blanket wrapped around it, adding that much more protection to the air inside. In light of that, it often makes sense to add new layers of insulation on top of your existing ones, especially in the attic or upper stories where hot air rises.

For more information on how insulation affects heating costs, or to install insulation in our attic or walls, contact the the Fresno heating system experts at Shaw’s Air Conditioning & Heating, Inc. We can help you determine how much more insulation is practical for your situation, then perform the installation with courtesy and care. In Fresno, heating repair services like ours are your best friend when it comes to saving money on heating. Give us a call today and let us show you what we can do!

How Efficient is High Efficient?

Tuesday, January 28th, 2014

Here in Fresno, heating systems are sometimes referred to as “high efficient” heating systems, a term that implies more heating power for comparative less energy. It’s a promising prospect and a high efficient heating unit often costs more than a comparable model with only normal efficiency levels. But before paying the extra money, you should know exactly what you’re purchasing and exactly how much it will contribute to your home’s comfort levels. How efficient is high efficient? Read on for the answers.

The easiest way to measure a furnace’s efficiency is to check its AFUE (Annual Fuel Utilization Efficiency) ratio. It’s measured as a percentage, detailing the amount of its consumed energy that actually goes into heating your home.  For example, is a given heating system uses 50,000 BTUs (British Thermal Units) of power and has an 80% AFUE rating, 40,000 BTUs of that power actually goes into heating your home.

So obviously, the higher the AFUE rating, the more efficient your furnace is. But the question still remains: what constitutes high efficiency? You’ll have to decide for yourself what’s efficient enough to be considered high efficient, but the U.S. Department of Energy has its own standards. In California, any gas-powered furnace with an AFUE of 90% or greater, and any oil furnace with an AFUE of 85% or greater qualifies for the Energy Star sticker: denoting models that contribute significantly to energy savings and use technologies that are widely available. That’s a good litmus test if you’re looking for high efficiency, and can be used as a quick “cheat sheet” if you find yourself overwhelmed by all the details.

Another good step is to contact a trusted professional to discuss your heating options in Fresno. He or she can determine how efficient is high efficient for you, then make recommendations on the best heating system to fit your needs. In Fresno, heating advice can be provided by the experts at Shaw’s Air Conditioning. We pride ourselves on complete customer satisfaction, and will spell out your options with you before installing a new efficient heater in your home with the utmost care.

3 Ways to Make Your Home More Heat Efficient

Monday, January 6th, 2014

Fresno heating issues often come down to nighttime temperatures, which can get quite chilly and require your household heater to function at its best. When the thermometer drops during the winter months here in Central California, most homeowners expect to pay higher energy bills in order to stay comfortable. You can reduce that pinch to your wallet by increasing your home’s energy efficiency. When coupled with regular maintenance to your heater, they’ll improve your bottom line significantly. Here are 3 ways to make your home more heat efficient.

  • Seal cracks. Loose fittings around your doors and windows can cause warm air to leak out, reducing your heater’s efficiency. You can address that problem by sealing the cracks with weather stripping, or calling a professional service to do it for you. Depending upon your budget, you might want to make more extensive improvements, such as adding double-sided windows or vinyl window frames. Not only do they eliminate leaks, but they can improve the resale value of your home to boot.
  • Add insulation. Insulation usually appears in your attic or the outside walls, retaining heat for your home in the winter and cool air in the summer. In many cases, you can add more insulation on top of what you already have to make your home even more “heat friendly” than it already is.
  • Consider a zone control system. This is either a series of individual heating units or a set of valves added to your existing heating system that divides your home into different zones. It lets you tailor the temperatures of each zones to match individual needs, or even turn off the heat in parts of the home that you aren’t using. That means less energy expended to keep you warm and lower bills in the bargain.

For more ways to make your home more heat efficient, or to schedule an installation or upgrade session, the Fresno heating system specialists at Shaw’s Air Conditioning are here to help. We operate throughout Fresno, CA, heating installation is our specialty, and we won’t rest until you are completely satisfied with our work.

How Does a Heat Pump Actually Work?

Tuesday, November 19th, 2013

Here in Fresno, heating technology is largely a wintertime concern, when temperatures drop and nights get chilly. Heat pumps make an attractive option in our kind of climate: combining the features of a heater and an air conditioner into an all-in-one unit. That versatility works very well in the Central Valley, and heat pumps do their best work when temperatures don’t drop below 40 degrees, making them a very good fit for here in Fresno. But how does a heat pump actually work? We’ve provided a brief guide below.

Heat pumps operate according to the same basic technology that governs air conditioners, with a few little twists. The pump is divided into indoor and outdoor sections, which comprise a closed-loop system that constantly circulates refrigerant gas. In the summer, the gas begins in the outdoor section of the pump. It moves through a compressor valve, which subjects it to a huge amount of heat and pressure, then onward into a series of condenser coils which bleed the heat out of it and into the outdoor air. The process converts the gas to a liquid state, though it is still under a great deal of pressure.

From there, the liquid moves inside, through an expansion valve which releases a set amount of it into a set of evaporator coils. As the liquid evaporates, it pulls the heat from the surrounding air, cooling it in the process. The cool air is then blown into your home via a fan and the gas returns to the beginning of the loop to begin the process anew.

Most air conditioning systems perform some variation of the same process. With heat pumps, the cycle can be “reversed” in the winter, so that the indoor coil becomes the compressor coil and the outdoor coil becomes the evaporator coil. That allows you to warm your home instead of cooling it.

In towns like Fresno, heating technology of this kind offers both convenience and savings, since heat pumps use less energy than traditional HVAC systems.
