Why the Efficiency of Your Air Filtration System Matters

Friday, February 27th, 2015

Cleansing the air that you breathe in your home is an admirable goal. However, too many homeowners fail to realize the fact that it is often more of a challenge than they first realize. If you are serious about improving indoor air quality in your residence, then you are wise to consider the installation of an air filtration system. You are wiser still to contact the indoor air quality specialists that you can count on to install your air filtration system in Lemoore, CA properly, as well as to ensure that the appropriate equipment is installed. To do so, just call the pros here at Shaw’s Air Conditioning. Not only will we help you to determine how best to combat issue with your indoor air quality, but we’ll also make sure that your air filtration system is of the right efficiency for your needs.

As you likely – and hopefully – realize, as you should be replacing or cleaning it regularly, there is an air filter built into your HVAC system. If you think that this is enough to improve upon the quality of the air throughout your home, though, think again. This air filter is likely of a fairly low efficiency, designed primarily to protect your HVAC equipment itself, rather than to clean up the air that you breathe in your home. If you hope to effectively trap airborne pollutants which can wreak havoc on your indoor air quality, then you are wise to invest in more efficient air filters designed for that purpose.

It is important to keep in mind the fact, though, that overly efficient air filters are really no better than air filters which are not efficient enough. If your air filters are rated to low in their MERV (minimum efficiency reporting value), then they will allow a number of pollutants to pass through. However, those filters with MERV ratings beyond what you need and what your system can handle can have a number of negative impacts on your system and your heating and cooling budget. They may create too much airflow resistance in your system, making it difficult for your HVAC system to distribute conditioned air effectively. Plus, your system will have to fight harder than it should to force air through the filtration system, which can increase energy usage, running costs, and lead to unnecessary strain on your equipment.

That way, your system will surely be of the right efficiency and in prime working condition. Call now for more details.

To ensure that you get the quality performance that you deserve from any air filtration system in Lemoore, CA, contact Shaw’s Air Conditioning.

What Kinds of Ductless Cooling Repairs Require Service?

Friday, February 20th, 2015

Ductless cooling may look very different from other systems, and the way a ductless system delivers air is certainly different from ducted systems, but when it comes to repairs, there are a lot of similarities between ducted and ductless systems. Some people may worry that a ductless system is more complicated to repair, but it isn’t any more complicated than a traditional split-system AC. Here are some of the common cooling repairs our Shaw’s Air Conditioning technicians see with ductless cooling systems:

Refrigerant Leaks

Whole-home air conditioning systems need refrigerant in order to operate. Refrigerant leaks are common repairs, but locating them can be challenging, and only certified experts can physically handle refrigerant. It is important to repair a refrigerant leak as soon as it is detected as these kinds of leaks can lead to serious operational issues with your system.

Condensate Drain Clogs

Each indoor blower has its own condensate drain line that drains the excess water from the blower to the outdoors. Condensate drain lines need to be cleaned at least once a year or they can clog from stuck debris and/or mold development.

Compressor Issues

The compressor resides in the outdoor unit. Several common problems that can develop with a compressor are issues with the capacitors, frayed or corroded wiring, refrigerant leaks, and motor issues. The compressor is responsible for pressurizing the refrigerant in the system, so if something is wrong with your compressor, your air conditioner will most likely develop issues with cooling.

Problems with the Indoor Blowers

The each indoor blower contains a set of evaporator coils, an air filter and a fan. Each of these components can develop issues that require the help of a trained professional.

As you can see, ductless cooling repair in Riverdale isn’t that different from traditional AC repair, but this doesn’t mean you should attempt repairs yourself.

Lupercalia: The Origin of St. Valentine’s Day

Saturday, February 14th, 2015

Many people may think of Valentine’s Day as a holiday essentially created by card and gift companies, but the truth is that the holiday has long-standing roots going back to the Roman Empire. The name “Lupercalia” has its origins in the word “lupus”, which means wolf, and the reason for this is that according to Roman pagan religion, the she-wolf Lupa nursed the two orphaned infants Romulus and Remus, the founders of Rome.


The Festival

The Festival of Lupercalia spanned two days each February, from February 13th to 15th. The festival was about fertility and was led by Luperci priests, known as “brothers of the wolf”. The festival was serious with intention (fertility) but was executed as quite a romp for both the priests and citizens of Rome. The process was this: two male goats and a dog were sacrificed at the beginning of the festival by the priests; two young Luperci were then anointed with the blood from the animals, and the hides of the animals were cut into straps. As food and drink flowed, the male priests would run around the city wearing nothing but thongs made from the animal skins, and they also carried a strap from one of the sacrificed animals. The strap was used to strike the palms of Roman women waiting for the priests in the city, as it was believed that being hit with the strap could help with infertility issues and a safe, healthy labor for women who were pregnant.


The Transition to St. Valentine’s Day

The Christian influence of the holiday came around the 5th century. The Roman Empire was still strong, but Christianity was rapidly taking hold throughout the world. It is believed that to try and remove the paganism from the holiday, the deaths of two men, supposedly both named Valentine, were added into the mix. During the 3rd and 4th centuries, a law created by Claudius II forbade young men eligible for military service to marry, because Rome wanted a strong army. The two men named Valentine were priests, and married young couples in secret. Both were found out and executed on February 14th, although in separate years. The Church made Valentine a saint (they chose one), and Lupercalia became St. Valentine’s Day.


Here’s wishing you and your loved one a Happy Valentine’s Day!

Signs Your Walk-In Freezer Needs Repair

Thursday, February 5th, 2015

Walk-in freezers are a part of your business because they are necessary. As such, when your freezer starts malfunctioning, it’s critical to your business to have it repaired as soon as possible. However, being able to get ahead of malfunctions and/or total breakdowns can save you both money and headaches, so here are some signs to be aware of that may indicate your walk-in freezer in Corcoran needs repair:

  • Seam leaks – leaks from the sheet metal seams are not normal and shouldn’t be treated as such. Seam leaks are an indication that excess condensation is building under the seam and is escaping. Not only is the water a problem, but mold and mildew growth may also be a problem.
  • Freezer is too warm – if items are defrosting in your freezer or there are other indications that it’s just too warm inside, call for help immediately before your entire freezer turns off.
  • Freezer motor is always running – your freezer operates in cycles, so it should never be on continuously. If it is, there is a secondary problem that is telling the freezer to keep running. Continuous operation can lead to burn out and damage, so if you have noticed that your freezer is running non-stop, call for an expert.
  • Major frost build-up inside freezer – it is normal to have a thin layer of frost on items coming from your freezer, but if there is significant frost build-up, this is an indication of a problem that requires attention.
  • Problems with the door – the doors of walk-in freezers are not like regular doors. To ensure that your freezer locks in the cold air, the doors have gaskets, special locking mechanisms and door closures. When any of the door components develops a problem, keeping the cold air inside the freezer can be a challenge.

Water dripping from motor area – one of the main components of your freezer’s mechanical operation is the evaporator. However, the evaporator can develop problems, and one of the telltale signs of a problem with the evaporator is water leakage.

Don’t wait for a total breakdown before repairing your business’s walk-in freezer.

If you see any of the signs that it’s time for repair, call the experts at Shaw’s Air Conditioning and schedule an appointment to repair your walk-in freezer in Corcoran.
