What Type of Air Conditioning System Is Right for You?

Wednesday, June 26th, 2013

Are you in the market for a new AC? It can be difficult to sift through the various system types and brands in the search for a system that matches your needs and budget. There is no shortage of options, which means that you need a guide. Selecting your AC is an integral part of the entire air conditioning installation process, and it should be taken seriously. Not just any AC will do. It needs to the right size, to have the right cooling output, and to fit within the parameters of your home’s budget. Most importantly, it needs to be installed by a consummate professional so that you can continue to reap its benefits in the years to come. So, what type of air conditioning system is right for you? Call the Fresno air conditioning technicians at Shaw’s Air Conditioning today to find out.

Let’s take a look at three of the major options available:

  • Central air conditioning. Central air is still the standard by which other systems are measured. It is a sturdy system that has an indoor evaporator/air handler and outdoor condenser/compressor that work in concert to remove warm air from your home, cool it, and then return it through an extensive network of air ducts. It also tends to be cost-effective, especially for homes with existing ductwork.
  • Heat pump. A heat pump is very similar to a central air conditioning system in that it is a forced air distribution system that uses ducts. But it is distinguished by its ability to reverse the refrigerant circuit, and also remove the cool air from your home during the winter months.
  • Ductless mini split. This is the premier ductless system and it works by avoiding the energy loss and indoor air quality issues associated with ductwork in the home. Each conventional outdoor unit can have multiple indoor units. These are placed in different areas of the home, and can be controlled separately.

While you’re in the process of selecting the right air conditioning system for your home, you want to take advantage of any system upgrades, as well. A digital, programmable thermostat is a great way to take better control of your cooling. Call Shaw’s Air Conditioning today for superior air conditioning services in Fresno, CA.

Energy Efficiency Tips for the Cooling Season

Wednesday, June 19th, 2013

It is important that you are able to keep your home cool and comfortable during the hottest weeks of the year. Doing so with the efficiency necessary to keep energy costs affordable, though, can be a challenge. That is why the Fresno air conditioning technicians at Shaw’s Air Conditioning have put together some helpful tips to help you boost your energy efficiency this cooling season. Do not allow high energy costs to dissuade you from keeping your home cool and comfortable this summer. Keep these tips in mind and see what else you can come up with your cool your home successfully throughout the long, hot days of summer.

One great way to boost your energy efficiency is to ensure that you change the air filter in your air conditioning system regularly. As your system operates this filer traps airborne pollutants as air passes through. If you allow too much dirt and debris to clog your filter, the airflow resistance that it creates may overwhelm your system. This will lead to decreased efficiency levels and even damage to your system.

You should also make sure that you are using your ceiling fans to supplement the performance of your air conditioning system. While fans may not actually cool down the air in your home, they can help to effectively circulate the air cooled by your air conditioner. This allows for more even, comfortable cooling which will allow you to raise the temperature at the thermostat a bit without sacrificing comfort.

By far the best way to keep your air conditioning system as efficient and reliable as possible, though, is to schedule routine air conditioning maintenance service with a qualified professional. Contact our Fresno air conditioning technicians today to schedule service. When every component of your AC system is able to operate properly and carry its own weight, it is easy to enjoy the most efficient performance possible.

For more tips on how to get the most efficient performance that your AC has to offer this summer, give the Fresno air conditioning technicians at Shaw’s Air Conditioning a call. We have the services you need to keep your energy costs down this cooling season. Contact us today for more information.

Visalia, CA Air Conditioning Tip: The Importance of the Right Refrigerant Charge

Tuesday, June 18th, 2013

We rely a lot on our air conditioning during the late spring and summer months. Whatever type of cooling system you might have, it operates by means of a specially designed chemical that circulates through the coils and compressor. You need to make sure that you have the right amount of refrigerant in your air conditioning system at all times. During installation, your AC was charged with a certain amount of refrigerant, and because the refrigerant cycle is a closed system, this level should never change. Well, technically. Unfortunately, problems can arise with your air conditioning system that may actually cause low refrigerant levels. Call Shaw’s Air Conditioning today for excellent air conditioning repair services in Visalia, CA.

Refrigerant is chemically designed to produce radical fluctuations in temperature as well as phase changes under different pressurized conditions. As the engine of the air conditioner, your compressor pressurizes the refrigerant, causing it to circulate through the coils. It moves through the evaporator in a cool, liquid state and interacts with the warm air brought in from the interior of your home by the blower motor. This interaction causes the refrigerant to evaporate. The compressor, which is located in the outdoor unit, takes this gas refrigerant and heats it up further so that when it circulates through the condenser coils, it actually dissipates thermal energy into the outside air. The cycle then continues.

But for all this to work as planned, your refrigerant charge needs to be at the correct level. While your AC does not expend refrigerant during the cooling cycle, other problems can cause low refrigerant. As long as your air conditioner was professionally installed, it should have the correct amount, but your system can develop leaks over time. Even pinhole punctures can allow refrigerant to leak into the outside air. If you have copper coils, they may be subject to corrosion, and this can cause pitting.

Low refrigerant can lead to higher energy costs because your compressor is forced to work overtime for the same amount of cooling. If severely low, it may even lead to warm air coming through the ducts, even when your thermostat is calling for cool air. Call Shaw’s Air Conditioning today if you’re in need of professional air conditioning repair services in Visalia, CA.

How Your Air Conditioner Works

Wednesday, June 5th, 2013

It can be incredibly frustrating when you need air conditioning repair service. Understanding how an air conditioning system works is a great way for homeowners to be able to identify problems with their equipment. Here at Shaw’s Air Conditioning , our Visalia air conditioning technicians thought it would be a good idea to put together a quick explanation of the different parts of your air conditioning system. We offer complete air conditioning services in Visalia, CA including installation, repair and maintenance for many different makes and models of systems.

Air Conditioning: The Basics

The whole point of an air conditioning system is to lower the temperature of your home by removing heat. The way that most central air conditioning systems accomplish that is to pull warm air from your home into a central unit, extract the heat, and then push the newly cooled air back into your home through a series of ducts.

Air Conditioning: The Split System

Central air conditioning systems are also referred to as “split” systems because they utilize an indoor evaporator coil system and an outdoor condensing coil system. Each coil has a fan and fan motor attached to it.

For the indoor unit, the fan pulls in warm air from your home and blows it across the evaporator coils. The evaporator coils are filled with a very cold refrigerant that absorbs the heat from the air.

The newly warmed refrigerant then gets circulated outside to the condensing unit. There, another fan blows outside air over the condensing coils in order to exhaust the heat from the refrigerant.

The refrigerant then heads to a compressor contained in the outdoor unit where it is compressed and heated. The compressed refrigerant heads back into your home to the evaporator coil. The refrigerant is rapidly evaporated which causes it to cool very quickly inside the evaporator coils where it absorbs more heat and continues again back to outside to the condensing unit.

For all your air conditioning repair, maintenance and installation necessities in Visalia, CA,  just call the Shaw’s Air Conditioning today.
