Family business established in 1999 and dedicated to old fashion customer service. Five years running received the Angie's List Super Service Award. We provide every customer with free estimates and email everyone a detailed itemized work description for any needed updates to make every home feel more comfortable while lowering their utility costs. We do not believe in high pressure sales tactics and you'll never be asked to sign a contract the day of the estimate. We insulate homes and lower utility bills. We install Foil Radiant Barrier * Attic Insulation * Update attic Ventilation * Replace HVAC Air Ducts * Spray Foam Insulation for new and existing homes & businesses. All customers meet directly with the owner, and because of this, we can offer all our customers a quality product at an affordable price. ARB does not offer a one-size-fits-all attic system. Every home and business is different and ARB develops a customized attic solution for every customer’s budget. The owner personally inspects every ARB Attic System installed and is at your job site from the start to finish. With over 20 years of service in the Quality Assurance Industry, Mr. Jones has come up with a simple philosophy that he demands be followed by all his employees, “Do it right the first time!” This simple philosophy ensures our customers receive the full benefits from a properly installed ARB Attic System EVERY TIME. ARB services the Dallas Metroplex and surrounding counties. We offer the highest quality products, materials and workmanship while providing unmatched customer service at every level.

"UPDATE Feb 2021: Not only was this a good solution for the summer but it also helped out during the winter storms that shut down Texas. Due to Neal the owner adding additional insulation along with the barrier itself, it protected my pipes from freezing up during sub zero temperatures. This was a lifesaver and resulted in this un-foreseen benefit and protection for my home. I would highly recommend affordable radiant barrier. The owner Neal comes out and personally conducts the estimate and he also arrives and personally supervisors and participates in the installation of the job itself. They get started early and work very hard. I can already feel the effects of the radiant barrier itself and I am very impressed. I ran estimates with three other companies and this by far was the best solution. Neal also installed additional insulation and an attic fan in addition to the radiant barrier itself. I also examined the radiant barrier product and it is higher quality and more durable than what you can buy at the store and better than what the other contractors were using."

Energy Attic, a consulting company for energy efficiency upgrades for residential or commercial. Our client's homes and offices are more energy efficient and save money. We specialize in foil radiant barrier, blown-in fiberglass insulation, and ventilation as a proven 3 part Energy Reduction System which will save you up to 40% on your utility costs. These home improvement upgrades will pay for themselves in energy savings and then continue to save you money as long as you live there. Energy tax credits are available through 2011. We have extensive construction experience and have a proven track record of installed clients. We will be happy to give you customer references. The radiant barrier we use is made from 99% aluminum foil and is 97% reflective - the highest reflectivity available. It is non toxic, has no fumes or off gassing and will not have to be reapplied over time. It can reduce your attic temperatures up to 40-50 degrees in the summer months and keep the heat from escaping during the winter months. We engineer our installations for each home to maximize air flow and heat reduction. We offer fiberglass blown in and batt insulation. We use premium insulation - Johns Manville Climate Pro. It has a lifetime guarantee against settling and does not deteriorate like many products. It is made from 25% recycled glass products and contains no formaldehyde. We also offer insulation removal services for fires, floods or contaminated insulation. The third component is ventilation. Solar fans are excellent because they actively remove hot air and moisture from your attic without using any electricity. They are extremely quiet and can withstand brutal Texas weather. We use Sunrise Solar Attic fans which are made in the USA and have an excellent warranty. Our estimates are free so call us now to start saving!

"As expected. Part was under warranty, but had to pay for Freon and labor. Everything is fixed and cooling again."

With a name like Dallas Plumbing Company, you may not think of us as air conditioning and heating experts, too. Fact is, in addition to our award-winning plumbing service since 1903, we are also one of the top licensed commercial and residential Heating, Ventilation and Air Conditioning Contractors in the Dallas - Fort Worth area. That simply means we know plumbing, air conditioning and heating and we do it right. Our goal is to earn your trust and keep you as a valued customer from now on. And, we back it up with our 100% Satisfaction Guarantee. Look to us for all your plumbing needs, and let us provide a free estimate on any new heating and cooling equipment you are planning to purchase. If your system needs cleaning or repairing, we can service all makes and models.

"I don't know who does their mailer copy. They offered a Water Heater Flush + Free Camera Inspection for $79. Sounded good because I wanted to see how deteriorated the unit is. They got here and told me the camera was for the drains and this was more of a whole house inspection, which I didn't want. The tech wanted to quiz me and I wasn't having it. I finally had to ask him to move his truck as he was blocking the neighbors drive. Needless to say, I'll never use them again. I'm not a fan of Bait & Switch!!!!"

Energy Efficiency Auditing questions, answered by experts

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.

Audits typically take 2-4 hours, depending on the property size and energy systems.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours.
