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

The Benefits of Ductless Cooling

Monday, August 18th, 2014

We are in the dog days of summer here in Alice, TX, and if it’s almost time to replace your air conditioner, you have some choices available to you. One of these choices is a ductless AC system. The word “ductless” can give the impression that ductless cooling in Alice isn’t whole-home air conditioning, but it is, and it has certain benefits that you may want to consider. As with any new air conditioning installation, it’s always best to hire trained professionals for your installation and repair needs, like the ones at Justice Air Conditioning & Heating.

How Does a Ductless System Work?

A ductless air conditioner uses an outdoor unit very similar to a traditional split-system AC, but instead of delivering the cool air via ductwork, a ductless system uses individual indoor blowers. Blowers are mounted in the rooms or areas in which you’d like cooling, and connected to the outdoor unit via a conduit that contains a power line, drainage line and refrigerant tube. The indoor blower contains a fan and coils, and provides cooling by blowing cool air directly. An outdoor unit can support up to 4 indoor blowers.

What Are the Benefits of Ductless Cooling?

The first, and most obvious, benefit is that ductless cooling does not require ductwork to deliver cool air, which allows non-ducted homes to have whole-home cooling. Other benefits include:

  • Better energy efficiency – with individual blowers, you cool only the spaces you need to, and not your entire home. Reducing cooling demands means using less energy, which can save you money in your monthly utility bills.
  • Customized comfort – each blower operates independently, allowing you to set the cooling you want for each particular space.
  • Easy installation – indoor blowers mount easily against walls, and the hole for the conduit is around 3” in diameter. Once the blower is mounted, it just needs to be connected to the outdoor unit via the conduit.

Ductless cooling in Alice can be a good choice for your home, but the best way to determine this is by working with an expert. Call us today and schedule an appointment.

3 Common Noises that Indicate the Need for Air Conditioning Repair

Monday, August 11th, 2014

Your air conditioner makes a lot of different noises. As the homeowner, you are most familiar with what the “normal” noises your AC makes are, so when you hear something that isn’t quite normal, that sound may indicate a problem is developing.

Air conditioning repair needs during the summer in Corpus Christi aren’t exactly what anyone wishes for, but they can happen – and if you are hearing strange noises coming from your AC, it may be time to call Justice Air Conditioning & Heating.

3 Types of Common Noises

There are a lot of noises you can hear from your AC, but here are 3 common ones that can indicate developing problems:

  • Grinding – the motors in your air conditioner – two fan motors and the compressor motor – use ball bearings to help with revolution. These ball bearings need to stay lubricated in order to do their job. If caught early enough, lubrication of the ball bearings should correct this.
  • Bubbling – refrigerant leaks are common with air conditioning systems. Sometimes, if the leak is located in a fairly visible position, you may hear a bubbling sound coming from your system. The reason the refrigerant bubbles is that it is under pressure; when there’s a leak, the pressure releases, bubbling the liquid refrigerant out of the hole. Refrigerant leaks can lead to a host of problems with your system, so if you hear bubbling, call for a technician.
  • Screeching – screeching can be indicative of a very dangerous situation: too much pressure in the compressor. The compressor operates under high pressure, but if it malfunctions, this pressure can escalate to a dangerous level. If you hear screeching coming from your AC, turn it off immediately and call a repair technician right away.

Don’t Ignore Sounds – Call a Professional

One of the biggest mistakes homeowners can make is to ignore strange sounds. Many times, your air conditioner will continue to work while making a strange noise, but this does not mean the system is ok. If you are hearing an abnormal sound, it may be time to schedule repair for your air conditioning in Corpus Christi.

What to Expect During Air Conditioning Maintenance

Monday, August 4th, 2014

During the summer in Corpus Christi, your air conditioner runs for a large portion of the day in order to keep the Texas heat out of your home. Because the components of your unit work so hard to keep you cool, there is a chance you will need repairs this summer. However, you can avoid unpleasant repair needs by scheduling biannual maintenance with a technician.

If you’ve never scheduled maintenance before, you may not know what to expect. A maintenance technician will check the inside and outside components of your system, thoroughly performing all of these valuable services.

  • Clean components – The technician will clean parts that may be affected by dirt or debris, such as the indoor evaporator coil and outdoor condenser coil.
  • Check refrigerant levels – Refrigerant must stay at a certain level at all times to properly transfer heat out of your home. If these levels drop, the air may never reach the desired temperature, or the compressor may suffer damages as a result.
  • General inspection – It would be nice to be able to schedule repairs on your own time rather than wait for a sudden breakdown. After inspection, a technician will let you know if any component needs repair so that you can address problems as soon as possible.
  • Ductwork inspection – The technician will also inspect the ductwork of your home to check for any obstructions that may get in the way of performance or efficiency.
  • Check the Drain – The condensate drain in your air conditioner helps with humidity, but it can occasionally become clogged. A technician may have to clear away debris so that your AC can function properly and to prevent leaks.

Why Schedule AC Maintenance?

Scheduling maintenance is one of the best ways to save money this year. Air conditioning maintenance provides all of the following benefits:

  • Prevents the need for repairs.
  • Increases the efficiency of your unit.
  • Extends the lifespan of your unit.
  • Gives you peace of mind knowing sudden breakdowns are less likely.
