Radiant Barrier Dallas

How Do Radiant Barriers Really Work?

To help you to understand how a radiant barrier works, let us first start by explaining a little about heat transfer. When talking about radiant barriers, insulation, HVAC systems and energy efficiency, it is important that we recognize that all of these things are about controlling heat.

You can also read a summary about what radiant barrier services we offer on our Radiant Barrier page.

There are also different types of radiant barrier, foil barrier and spray barrier. You can read a previous post about the difference between the two: Foil Radiant Barrier vs. Spray On Radiant Barrier

If you were wondering why you might need radiant barrier, it might be helpful to read our post before you read the remainder of this article. Why Radiant Barrier?

A: Understanding Heat Transfer
Heat transfer happens in homes and building in three distinct ways.
* Conductive heat transfer (conduction)
* Convective heat transfer (convection)
* Radiant heat transfer (thermal radiation)

Conduction is the least efficient method of transferring heat, and in a kitchen analogy, that would be an equivalent of boiling water in a pot over a stove. The fire heats the pot and the pot transfers its heat to the water and the water eventually comes to a boil. The key point here is that conduction is the transfer of heat through
direct physical contact.

Convection is more efficient than conduction, and in our kitchen analogy, convection would be the use of an oven to heat food. Convection heat transfer is the process by which heat is circulated in an area through the air and/or fluid. The key point here is that heat is transferred through air circulation.
Radiant heat otherwise known as thermal radiation is the most efficient type of heat transfer and the best example in our kitchen analogy would be the use of a microwave. Radiant heat is generated when heat from the movement of charged
particles within atoms is converted to electromagnetic radiation. In a home or building, radiant heat refers to heat radiated from objects and materials, such as incandescent lights, concrete flooring and the sun. It is also important to note that radiant heat moves through the air without heating the air, instead it will heat the first surface that it touches, and this surface will then re-radiate that heat in the space making it feel warmer when you are in that space.

In general, heat transfer between the interior and exterior of a home or building is bad and decreases the efficiency of the heating and cooling system. There are some special conditions where heat transfer is used to increase the efficiency, such as traum walls, thermal masses, and other natural heating and cooling techniques.
But for the most part, in a typical home or building which relies on mechanical means of heating and cooling, heat transfer is the enemy.

So, it makes sense to stop as much heat transfer as possible. This is why insulation is used in all structures. Insulation is great at reducing convective heat transfer, while also reducing some radiant and conductive heat transfer as well. However, the typical amount of insulation in a home or building (anything below R39) is
simply not enough to stop the majority of radiant heat from infiltrating the structure.

Winter Heating Tips

Eastin Air offers many services that can help insure your home is operating at a high level of efficiency and that it is operating safely for winter weather. We seal air leaks, offer Home Energy Audits, Blower Door Tests, Duct Cleaning and Radiant Barrier to name a few.

With colder weather already hitting the Dallas area, we decided to provide a few winter heating tips. Some of these will relate directly to your home heater or furnace and other winter heating tips will relate to portable units.

  1. Keep anything that can burn at least three feet away from your furnace, fireplace, portable heater or wood stove.
  2. Have a three foot “kid free” zone around portable heaters and fireplaces.
  3. Never use your oven to heat your home.
  4. Remember to turn your portable heating units off when going to bed or leaving the room.
  5. Test smoke alarms monthly.

In addition to these tips, it is recommended that you have your heater or furnace inspected annually. With your home heater or furnace inspected, you can be assured that your heating system will work properly and efficiently through the winter season.

In addition to having your heater professionally serviced, it is a good idea to check your chimney, check your heat exchanger, inspect ducting and piping, check safety devices and your carbon-monoxide detector.

Heating Tips Dallas Winter

Easting Heating & Air serves the entire Dallas metroplex, servicing, installing and repairing heating and A/C units. With winter not too far off in Dallas, we thought we’d share some heating tips to help you save some money. Maintaining a lower temperature, proper insulation, sealing air leaks and lowering your water heater temperature are all good items to consider.

One of the easiest ways to save money on your heating costs is to simply lower the temperature in your home. Reducing the thermostat by just one degree can save around 3 percent on your home energy bill. For those that can’t do with the decrease in heating temperature, lowering the temperature by 10-15 degrees while at work can help you save about 10 percent. You can add another 10 percent if you lower the thermostat by 10-15 degrees overnight.

If you don’t have a programmable thermostat, we can come out and install a thermostat that will allow you to program the temperature of you home according to the time of day.

In addition to saving on your air heating costs, you can also save on your gas bill or electric bill by reducing the temperature of your water heater. Most water heaters are set at 140 degrees.  You can turn it down to 120 degrees without noticing a difference in your water temperature or the time it takes for you water to heat.

Proper insulation is imperative to keeping your home warm in the winter. Eastin Air can install new insulation in the attic or complete a free Home Energy Audit to determine if you have any areas of concern.

In addition to proper insulation, air leaks need to be sealed. Sealing air leaks is a quick service that will have a huge benefit on the integrity of your home, your energy bill and general warmth of your home. If air is leaking out, the heat is leaving your home, causing your heater to work harder and costing you more money.

Reasons for Improving Home Energy Efficiency 2

To keep a high home energy efficiency level, we’ve listed some HVAC products or services below like a blower door test or an attic tent. Eastin Air has provided quality service to the Dallas area for over 25 years.

Air Infiltration. Seal all non airtight recessed can lights. There is a retrofit to your existing can lights. It replaces the trim with a cone shaped insert with a gasket on the end, which will seal off air flow. Energy Star states that on average they cost about $15.00 per year in heating and cooling cost alone.

Older can lights have small openings in them. These openings add up to a lot of open air movement from the attic and walls directly into the home. The air that moves in is dusty, hot and full of humidity. You will notice less dust and feel more comfortable.
Attic Tent. Seal and insulate pull-down stairway with an attic tent. An Attic Tent is a brand of product designed for this purpose. It is a reflective, insulated, zip open bag that is sealed to the attic floor. The steps fold up into it and then when attic access is needed you simply pull down the stairs and unzip the tent.

This will seal off any air movement from the attic as well as insulate the door. This uninsulated door allows rapid heat transfer into the home.

Seal Plumbing at wall under sinks. Using caulk or expanding foam, seal air infiltration under sink cabinets.

Seal HVAC closet from the living area. This closet is allowing attic air to be drawn into the living area and has the potential to
bring in carbon monoxide when vent fans are running. The above items deal with air infiltration. Air infiltration can account for about 30%
of heating and cooling cost according to national research. A blower door test would show that these areas need attention. Reducing air infiltration can significantly reduce energy usage while increasing home comfort. Reducing air movement from the attic can make a big difference in IAQ (indoor air quality). This is very important, especially with young children and adults that are more susceptible to respiratory ailments such as asthma, bronchitis, and allergies. The EPA ranks IAQ as the 5th leading causes of health problems in the US.

Insulation blanket to water heater. Wrap water heater with an R-8 insulation blanket. This will reduce the number of times your water heater has to run during a day to keep water hot.

Clean Dryer and Dryer vent. Dirty dryer vent lines increase drying time, increase energy cost and are a fire hazard. Dryers and dryer vents account for about 15,000 fires annually. This should be done every year or two. The above improvements will pay for themselves over time and are the most relevant to comfort and energy savings.

Clean all ducts with our RotoBrush system. This includes removing and cleaning the grills. We then use an anti-microbial/anti-fungal fogger to sanitize the systems. Once complete, we will seal the sheetrock, before reinstalling the grill. Once the inside of the duct work has been contaminated, it allows dust, mold and pollutants to re-circulate around the house. As with air infiltration, cleaning your ducts will also improve indoor air quality.

Reasons for Improving Home Efficiency 1

There are many reasons for improving your home energy efficiency. We’ll go over a few products and services that we offer at Eastin Air and provide the reason they make your home more energy efficient.

Radiant barrier to the underside of your roof deck using tear resistant foil type. This is stapled to the bottom of the roof joist.
Radiant barrier can lower your attic temperature by 40 degrees, improve HVAC duct performance up to 50% (duct work and AC unit is not subjected to the extra heat of the attic), does not trap moisture, low heat re-emission, reflects radiant heat away from living areas, improves efficiency of insulation and will save an average of 10 –15% on cooling costs. Foil radiant barrier typically reflects solar radiation a minimum of 22% better than painted or sprayed on radiant barrier.

Insulation and seal all plumbing and electrical penetrations in the attic. This will increase the insulation value of your home. We recommend an R-38 value, which is the current minimum requirement for new homes in this area. R-49 is what the Department of Energy recommends for this area. Insulation will lower your energy costs and allow your home to stay at a more even temperature for better efficiency and comfort. Your HVAC will run less and last longer. Sealing attic penetrations will stop most air movement through the walls and ceiling into
the living areas by way of electrical outlets, switches, and other openings in the sheet rock.
Ventilation. Without proper ventilation, tremendous heat builds up in the attic. This heat is then transferred into the living areas. Insulation slows down this movement, but heat still travels into the living areas. Proper ventilation allows air movement to exhaust this hot air build up and allow the insulation to do its job. Ventilation should be by way of soffit vents down low in the soffit, or overhang of the roof, and ventilation in the upper areas of the roof, by way of ridge vent, gable vents, passive vents, wind driven vents, electric powered fans, or solar powered fans.
Radiant barrier, insulation, and ventilation all work together as a unit. Each one individually does a good job, but as a package, they really make a difference. These measures will pay for themselves. Year after year, you will reap the benefits of lower utilities and a more comfortable home. These three items can immediately save as much as 30% on heating and cooling costs. Not only are you investing in your comfort, reducing your energy costs, you are also increasing your home’s potential resale value.

Seal duct work connections, splices, air handler seams, and plenum with permanent mastic on your old unit.
The home loses heated/cooled air to the attic and draws hot/cold air through the return. A duct system should not leak at all. Even the smallest hole in your return duct would be like opening a window from your living areas to your attic, due to the negative pressure that sucks air through your unit. The air that moves in is dusty and full of humidity, causing your AC unit to work harder.

Air Duct Leaks

Leaking Air Duct DallasAir Ducts are used to distribute heating and air in houses with forced-air heating and cooling systems. In the average Dallas home, about 20% of air is lost due to air duct leaks. The result is higher energy bills and difficulty keeping the house comfortable, regardless of the temperature.

Signs that you might have an air duct leak:

  • You have stuffy rooms that never seem to feel comfortable
  • You have rooms that are difficult to heat or cool
  • You have high summer and winter utility bills
  • Your ducts are located in the attic
  • You find tangled or pinched tube in your system

There are many benefits to a sealed air duct system. Your heating and cooling systems will run more efficiently and therefore provide lower utility costs.

At Eastin Air, we seal air leaks, improve the performance of your system, help keep your utility bills down and provide a full Home Energy Audit.

Sealing your Air Ducts will make your home more comfortable. The temperature will be easier to regulate in your home with your air conditioner and heater.

Sealing leaks can also improve your indoor air quality. Fumes from outdoor chemicals, insulation particles and dust can enter your duct system. Sealed Air Ducts can prevent the pollutants from entering your indoor air.

During use other household items like dryers, dish washers and water heaters can release carbon monoxide into the air. If you air ducts have a leak, that gas enters your air duct system and then your house. Sealing your air ducts will prevent this from happening.

Repaired Air Ducts help your home run more efficiently and save you money on heating and cooling costs.

Fall HVAC Tune-up

Fall is a great time to have your HVAC system inspected, tuned up or maintained. HVAC maintenance is recommended twice a year. Fall and Spring are great times for HVAC checks. Fall tune-ups or inspections for your furnace or heating system are important to ensure that your heating system is going to perform well during the winter. Although winters aren’t typically unbearably cold in North Texas, we have had several days of snow in winter over the last couple of years.You want to ensure that your furnace is in top working condition to help improve your home energy efficiency and air quality.

Having your furnace and A/C unit inspected and maintained by an HVAC professional will increase the efficiency of your units, help  them last longer and save you money on energy cost. Eastin Air provides many energy saving tools. We can perform a home energy audit, blower door test, or install radiant barrier if you want a more energy efficient home.

As recommended by Energy Star, we check all gas connections, gas pressure, burner combustion, and the heat exchanger. If gas connections are not working properly, it is a fire hazard. Units will operate less efficiently and they are not as safe if the heat exchanger or burner combustion isn’t functioning properly.

Fall HVAC tune-ups are essential for your home to heat properly in the winter and continue to function safely and properly.

Keeping your HVAC system and specifically your furnace in good working order can help other parts of your heating system to stay clean and work efficiently. Your air ducts and overall air quality can be effected by your furnace.

Schedule your Fall HVAC Tune-up today. Remember it is a good idea to have an inspection done twice a year. Once in the Spring for the air conditioning unit and once in the fall for the furnace.

Eastin Heating and Air proudly serves the Dallas area, including Highland Park, University Park, Plano, Frisco and other DFW areas.

Air Duct Cleaning

Air duct cleaning is one of the best services you can perform on your home. Do you care about the air you breathe? If so, you should consider air duct cleaning.

Air Duct Cleaning can provide:

  • Fresh indoor air to breathe
  • Less Dust
  • Lower Utility Cost
  • Less Wear and Tear on your A/C Unit and Furnace

At Eastin Air we provide Air Duct Cleaning for all sizes of homes and offices. Once cleaned, the air in your home or office will have less mold spores, pollen, dander and dust mites.

Anyone can benefit from an air duct cleaning, but it does help some more than others. Customers with allergies, pets with long hair or those that have several pets seem to notice the largest difference. However, we’ve cleaned many air ducts for customers that don’t have any pets or allergies and they noticed a big difference as well in their indoor air quality.

Most homeowners have no idea what goes on in their air ducts. It isn’t a place we go and look very often, but an cleaning your air ducts can have a huge impact on your air quality. Air ducts can become littered with years of dirt, debris and allergens like pollen, dust and pet dander. It is recommended that you have your air ducts inspected every 2 years. That doesn’t mean you will need a cleaning every 2 years, but you should be aware of their condition.

An air duct cleaning provides a healthier living environment, reduces your energy bills and helps reduce allergies. It is important for you and important for your HVAC system. Clean air ducts help your A/C unit and furnace run more efficiently prolonging their life and saving you money on your monthly energy bills.

For more information or to schedule an appointment call Eastin Air today. We also provide free energy audits of your home or business so you can be more informed of the efficiency in your home or office.

Taking Care of Your Air Conditioner

Taking care of your Air Conditioner is extremely important to prevent the installation of a new Air Conditioner and to help lower your energy costs. Did you know that 40% of a typical homeowners energy expenses are comprised of heating and cooling? That is almost half of your energy cost. Here at Eastin Air we are very big proponents of regular A/C Maintenance and cleaning. Air Conditioners are just like car engines, airplanes or other mechanical devices. To run properly and efficiently they need regular maintenance.

What is the best way to take care of your air conditioner? We’ll we have a few tips for you, but to be sure your unit is properly maintained you should have a licensed technician maintain your air conditioner on a regular basis.

Check the Controls of the Air Conditioner

This may sound odd, but you want to make sure the unit turns on and off properly without any issues.

Check the Thermostat Settings

Making sure your A/C unit turns off when you leave and back on just before you get home is a good way to save on energy costs and extend the life of your air conditioner. If you leave for work at 7 AM and nobody is in your home until 6 PM, this could save you 11 hours of running your AC unit throughout the day.

Lubricate Moving Parts

Any parts that move should be properly lubricated to insure they flow and move easily. Any parts that create friction in their movement cause your air conditioner to work harder and can cause higher energy costs

Change Your Air Filters

Making sure you buy and replace quality air filters is a large part of keeping your air conditioner running smoothly. A clogged filter will cause your unit to work harder, increase your energy cost and shorten the life of your air conditioner.

Clean Condenser Coils and Evaporator Coils

Dirty coils cause your air conditioner to run longer because it cannot function well, causing increased energy costs.

If you need your air conditioner maintained, an new AC unit installed or a free home energy audit, contact Eastin Air today.
