Two Ways to Get Zone Control with Air Conditioning Installation

Thursday, January 29th, 2015

Wouldn’t it be nice if all of the members of your family got to set the temperature in their own rooms to their exact individual preferences? You would hear no more complaints about the temperatures throughout the home, or that the upstairs rooms were warmer than the downstairs rooms. This is achievable when you call a technician for zone control installation. With a central air conditioning system, this may seem difficult to accomplish, but it usually takes only a few hours to a day when completed by a trained technician. And without any ducts at all, you may worry that your only option for zone control is a series of window AC units, but this is also untrue when you choose to install a ductless AC in Corpus Christi

Zone Control System in the Ductwork

When you have an existing set of ducts, a zone control system will require some modification. A technician must access your ductwork through the crawlspace or the attic in order to cut it open at points and install dampers. Each damper controls a particular zone, or single room, in the home. When an individual lowers the temperature in the room, the damper will open for more airflow. When no AC is needed in a room, the damper shuts. Each damper has its own thermostat and there’s usually a master thermostat that also controls each damper individually or all of them at once.

No Ducts? No Problem!

However, if you don’t have any ductwork at all installed in the home, it doesn’t limit your ability to get zone control. A ductless AC is one of the most efficient air conditioning and heating choices you can make for your home. This requires the installation of an outdoor unit and (usually) multiple indoor units. The indoor units connect to the outside unit via a cable containing the refrigerant line and electrical components, which means the only renovations you’ll need to make is having a small hole drilled in the wall. Several units mounted on walls in various areas are necessary to cool an entire home properly and efficiently, but the benefit of this is that each unit is wired to its own thermostat for built-in zone control.

The Safety Components of Modern Furnaces

Thursday, January 22nd, 2015

Furnaces have always dealt with materials that could be quite dangerous under the right circumstances. Far from resulting in their abandonment as a primary method of home heating, this simply led to the invention of more and better safety components over the years. Modern furnaces now have so many kinds of safety measures that they’re one of the safest combustion heaters around. Let’s examine a few of the safety components that can be found in modern furnaces.

The Limit Switch

The limit switch can occasionally be split into two different parts, but for the sake of brevity we’ll address it as one thing. The furnace limit switch is a small device that measures the internal temperature in the furnace plenum, which is the central chamber of the furnace. When the temperature inside the plenum reaches a certain point, the limit switch turns the air handler on to begin circulating air throughout the house. It doesn’t turn the air handler on right away, because that would blow cold air through the house until the furnace had a chance to warm up.

The limit switch also turns the furnace off if the temperature in the plenum gets too high, so the system won’t overheat. This is why it is listed as a safety component. This second function is also the cause of the behavior “short-cycling,” in which the furnace rapidly turns on and off as it overheats and provokes the limit switch.

Thermocouple/Flame Sensor

For furnaces that use a standing pilot, there are a number of different sensors that determine when to open the gas valve to feed the flame and when to close it. The thermocouple is an older part that created an electrical current when exposed to the pilot light. This current would travel to the gas valve and open it. When the pilot light blew out, the current would cease and the gas valve would close to prevent gas from flowing into the house. Modern flame sensors use different methods, but with the same result.

Reasons to Be Concerned about the Air Quality of Your Commercial Property

Thursday, January 15th, 2015

The health and safety of the people on your commercial property is important to you. In fact, most facets of commercial safety are monitored by local and federal codes, such as the width of hallways, the height of sinks, and even the position of the doorknobs. Your place of business should be accessible to anyone who passes through, including those with asthma and allergies.

Asthma and allergy symptoms are triggered by poor indoor air quality, especially when mold spores, bacteria, and dust are floating through the air. It’s important to consider the well-being of your customers, clients, employees, and tenants, especially since allergies may affect up to thirty percent of the people on your property and because contaminants in the air can cause symptoms even in those without any preexisting conditions.

The filter that is already installed in your property’s central air conditioning and heating system may not be able to trap most of the contaminants floating around in the air. Local building codes usually require a certain level of ventilation, but this too may not ensure that you have adequate protection from hazardous particles recirculating through the ductwork.

It’s important to work with a commercial indoor air quality specialist to choose a filter with a high enough MERV rating (minimum efficiency reporting value). The higher the MERV, the more effective a filter will be at straining out smaller and smaller particles, and the smallest contaminants may cause the most irritation.

You should also consider the possibility that moisture will result in some ill effects. Too much moisture on your commercial property can allow for the development of mold. Condensation accumulates on the indoor air handler of your property’s HVAC system and mold may end up forming along the inside of the ducts, which creates the perfect environment for mold and bacteria. A UV air purifier will kill and sterilize microorganisms living on the indoor air handler, while a dehumidifier in the ducts can eliminate moisture throughout the entire property.

We can help to keep you on track with commercial indoor air quality installation in Corpus Christi.

How Dirty Coils Can Lead to Air Conditioning Repair

Thursday, January 8th, 2015

It may be a given that the parts of your air conditioner don’t work very well when any single component is damaged. When an air conditioning part is broken, damaged, loose, or out of place, the air conditioner cannot run as it was supposed to. But it may surprise you to learn that dirty parts can be just as detrimental to your air conditioner’s effectiveness.

Your air conditioner has two coils, one of which is located in the outside compressor unit and one of which is part of your indoor air handler. Either of the coils may become dirty over time, although the outside coil is more vulnerable due to its potential exposure to the elements. And when these coils become dirty, your air conditioner may struggle to run properly, meaning your unit is extremely inefficient and your air conditioner may begin to breakdown, forcing you to seek urgent air conditioning repair in Portland, TX.

The inside and outside coils are responsible for assisting in the heat exchange process necessary in air conditioning. After refrigerant pumps from the outside unit to the inside coil, it undergoes evaporation, changing from a liquid to a gas. When it does, it’s able to absorb heat. As it moves to the outside coil, it condenses back into a liquid. And when it condenses, it’s able to release heat back into the atmosphere. This means that the coils are essential to proper AC function. So when they become too dirty, this process is delayed and you may not feel enough cool air through the vents, leaving you headed to the phonebook for an AC technician.

And when one part is not working properly, the other parts begin to work a little bit harder to compensate. As these components are pushing through to make sure your home reaches the desired temperature, they may begin to wear out, and may even break down well before they should. Furthermore, if the inside evaporator coil is dirty, it can actually freeze. This is because the refrigerant cannot absorb enough heat to keep the coils in the right conditions.

Can I Install an Air Conditioner on My Own?

Monday, January 5th, 2015

An air conditioner is a complicated piece of equipment, with plenty of electrical components and large mechanical units that must be installed properly in order to operate. But these days, do-it-yourself projects are all the rage. Many people enjoy looking up instructions and guides on putting together and installing anything from coffee tables to home television sets. And while you may be able to locate some literature on the subject of air conditioning installation, it’s simply a job best left to the professionals.

Air conditioning installation is a lot more complicated than you may initially suspect. Many people abandon their unassisted installation efforts in the early stages, but others go through with the process to try and save a little bit of cash. Because of the materials involved in proper HVAC installation, however, it’s unlikely to save you any money at all, particularly if you need repairs later on due to faulty installation.

In general, D-I-Y installation is simply not worth it. First, the indoor and outdoor unit must be properly secured and hooked up to the ductwork and refrigerant line. Improper sealing or mounting will lead to repair needs early on in the life of your system. Your air conditioning system has to work a lot harder when something is not quite right, which leads to worn-down parts that become overworked as time goes on. Professionals provide thorough inspection after installation checking for anything that is loose or out of place. They’ll use professional grade tools to verify proper air pressure and refrigerant levels, as low refrigerant could lead to reduced cooling and compressor failure.

Another reason professional installation is vital is because it is important to select the correct size for your home. If your air conditioning system is undersized, it won’t provide enough power to cool down the house. If it’s oversized, you it may short cycle, causing the compressor to overheat. Sizing involves complex engineering equations that usually require extensive training to understand, another reason to leave it up to trained experts.

The History of “Auld Lang Syne”

Thursday, January 1st, 2015

There are numerous different traditional songs associated with Christmas—but there is only one song that comes to mind immediately when people think of New Year’s Eve: “Auld Lang Syne.” It is hard to find a New Year’s Eve party where people won’t leap into singing “Should old acquaintance be forgot…” as the first stroke of midnight sounds. This tradition encompasses the globe, with almost every culture that celebrates New Year’s on January 1st breaking into song with the same set of lyrics.

Where did this song come from? And what do the words “auld lang syne” actually mean? The best place to ask these questions is Scotland. The Official Gateway to Scotland website calls the song “one of Scotland’s gifts to the world, recalling the love and kindness of days gone by, but in the communion of taking our neighbor’s hands, it also gives us a sense of belonging and fellowship to take us into the future.”

The melody of the piece originates from Lowland Scots folk song tradition. It was legendary Scottish Romantic poet Robert Burns (1759–1796) who created the words we know today, however. During the later years of his life, Burns dedicated much of his work to collecting Scottish folk tunes and giving them new life. The first mention Burns makes of “Auld Lang Syne” is in 1788, when he calls the song “a glorious fragment.” Burns wrote new lyrics to the old melody, and used the words “auld lang syne,” which is Scottish for “old long since,” and which can be translated into standard English as “long, long ago” or “days gone by.” The phrase was already known in earlier Scottish poems and folk songs, and appears to be the equivalent of “Once upon a time…” for Scots fairy tales.

Soon after Burns introduced the song to the public, it spread across Scotland as a New Year’s custom, and then to the rest of Great Britain. Scottish immigrants took the song with them as they moved across the globe, and by the middle of the 19th century it was a holiday tradition throughout the English-speaking world. By the close of the 20th century, it was a global phenomenon to ring in the New Year.

We imagine that you’ll end up singing or hearing “Auld Lang Syne” at some point this New Year’s (maybe you’ve already heard it while watching It’s a Wonderful Life).

All of us at Justice Air Conditioning & Heating Inc. would like to take this opportunity to wish you a happy coming year in the tradition of the song.
