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.

Start out the next cooling season in the right way by calling the professionals at Justice Air Conditioning & Heating for quality professional air conditioning installation in Sinton.

How Zone Heating Installation Can Save You Money

Monday, October 20th, 2014

The standard ductwork for a central heating system is a “one size fits all” kind of layout. The ductwork carries the same heat to all rooms of the house with no ability to differentiate temperatures between each area. Zoning is the practice of altering the ductwork in a home to allow greater control over the distribution of heat.

Now, a common amateur version of zoning is to manually close the heating vents in each room until only the rooms you want are receiving heat. This is actually harmful to your heating system, and can cause quite a bit of damage if done repeatedly. True zoning is accomplished by a professional altering the ductwork. This usually involves installing a damper and thermostat for each room you want heated.

There are a couple of unique benefits to this kind of zoning. Having a thermostat for each room gives you far greater control over how you want the house to be heated. A central thermostat can only measure the temperature in the area around it. If a room in the far corner of the house is freezing, the thermostat on the other side of the house has no way of knowing that. This makes uneven heating a common problem in houses with a single thermostat controlling the heat. Zoning all but eliminates this problem by having a thermostat monitoring each room.

Zoning also saves a sizeable portion of money on heating bills. A central heating system will always heat the entire house, whether or not most of it is uninhabited. This wastes a great deal of energy on rooms where the temperature doesn’t matter all that much. Zoning allows you to limit the heating system’s operation to only rooms where you need the heat. Over time, this can even save you as much as 30% on your heating bill.

Air Conditioning FAQ: What Is the Compressor?

Monday, September 29th, 2014

Of the many components that make up a modern air conditioner, the compressor is the true “heart” of the system. Its function is, in many ways, similar to the heart inside a body. Without a working compressor, you don’t have a working air conditioner.

Making sure that the compressor in the AC that cools down your home works at its best and without excessive wear is one of the most important parts of regular maintenance. A failed compressor needs to be replaced, which is often the most expensive repair an air conditioner might need; in most cases of a burned-out compressor, it is more cost-effective to replace the complete cooling system.

If you need maintenance or repairs to keep the compressor in your air conditioning in Sinton, TX running, call your local AC experts at Justice Air Conditioning & Heating.

Compressor basics

The compressor is housed in the outdoor condenser unit of an air conditioner, where it is connected to a motor. The motor runs the pump action of the compressor that allows it to do its job, which is to compress the refrigerant in the system and change it into a hot, high-pressure gas. This is one of the essential steps of the heat exchange process of the air conditioner that allows the system to remove heat from inside a home and exhaust it to the outside.

Basically, it is the compressor that gives energy to the refrigerant that propels it around the air conditioner. When the refrigerant enters the compressor, it is in liquid state after having passed through the evaporator coil indoors. In order for the heat exchange cycle to continue, the refrigerant must increase in heat and pressure. The compressor, by reducing the volume available to the liquid refrigerant, raises its pressure and turns it into a hot gas. This gaseous refrigerant then moves to the next area of low pressure, which is the outdoor coil, and there it releases its heat, and continues to the indoor coil.

Without a working compressor, the refrigerant will not cycle through the system, and it will not go through the important temperature changes necessary for it to absorb and release heat. If the compressor in an AC breaks down, the system will be nothing more than a set of fans blowing around room-temperature air.

If your air conditioner begins to “hard-start,” struggling to come on and making grinding or clicking noises as the compressor starts, you will need to call for air conditioner repair technicians right away: this stress could inflict irreparable damage to the compressor. Any time your AC shows signs of losing its cooling ability could also mean there are compressor issues, so do not hesitate to contact Sinton, TX air conditioning experts like those at Justice Air Conditioning & Heating. We have technicians ready 24 hours a day to assist you.

How a Radiant Barrier Benefits Your Home

Monday, August 25th, 2014

Keeping the heat out of your home during a Texas summer can be a tall order; this is one of the reasons why air conditioning in our part of the country isn’t a luxury, it’s a necessity. Good insulation in Sinton is important in maintaining a cool home during the summer because it slows heat transfer. But there is an additional step you can take to reduce summer heat gain, and that’s installing a radiant heat barrier. Radiant heat barriers are very effective at reducing radiant heat. However, you don’t want just anyone to install one, so call the professionals you can trust: Justice Air Conditioning & Heating.

What Is a Radiant Heat Barrier?

A radiant heat barrier is a reflective insulation barrier that is installed just under the roof of new buildings (or newly-installed roofs) or inside open attic spaces in existing buildings. The barrier consists of large plywood or OSB boards where one side is covered with aluminum sheathing. These boards are installed with the reflective side facing toward the inside of your home and reflect back the radiant heat from the sun. For the sheathing to work properly, the boards need an airspace of at least ¾ of an inch because anything close to them will heat through conduction heat.

Types of Heat

It’s important to understand how heat flows in order to understand how a radiant heat barrier helps:

  • Conduction heat – conduction heat flow is the flow of heat between two materials. An example would be a metal spoon heating up in a cup of hot coffee – the heat is conducted from the hot coffee through the spoon.
  • Convection heat – convection heat is the flow of heat via gases or liquids. Heat moving through air would be an example of convection heat.
  • Radiant heat – radiant heat is heat that travels in a straight line away from any surface and heats anything solid that absorbs its energy.

Benefits of a Radiant Barrier

There are several important benefits to installing a radiant barrier:

  • Can reduce heating and cooling cost
  • Can increase comfort levels
  • Increases energy efficiency
  • Helps keep heat in during the winter
  • Helps keep heat out during the summer
