Cord spent about 20 minutes answering my questions about how long they had been in business, how they would handle unexpected problems, and what I could expect.

The installation of new ac ducts went very smoothly and the workers cleaned up after finishing each day. I would highly recommend Green Collar to anyone needing duct replacement or repair.

The owner of the company provided our estimate, the team arrived within the time windows predicted, they were competent and courteous, and they did a *fantastic* job modernizing our system to heat quietly and evenly throughout. They added a vent to a bathroom that had been inexplicably left without one, improved the insulation throughout, and added an attic walkway for safety. We've been tolerating very uneven temps and noisy vents for the past 10 years, and I wish we would have discovered Green Collar sooner! It is *NICE* in here. I have no reservations about recommending Green Collar's services. Stay warm, y'all!

Stephen also provided us a list of DIY items to improve our home energy efficiency. The entire audit process was professional, clean, and worth every penny. Stephen has the education, certifications, and experience to be the best in the Austin area. I highly recommend ECAD Specialists.

DO NOT DO BUSINESS WITH THIS COMPANY. They do not properly identify what is needed for a successful…read moreinstall, and do not properly address issues when they arise. Sorry for the long review...but please read on to hear my horror story with this sorry excuse of a company. I don't normally write reviews (good or bad), but my poor experience with this company cannot go unheard. I feel obligated to warn others of their frankly criminal business practices. I originally called them out to take a look at my old HVAC that was no longer producing cold air. They identified the Freon was low and filled it back up. Worked well for a bit, but then got low again...indicating their was a leak in the system. The unit was so old, we decided to replace the unit instead of fixing it. The new unit was installed, but not without issue. I chose what they described as their go-to brand - American Standard. Apparently their technicians do not know how to install their go-to brand, because it took several days and several different technicians to get the install completed. A year later, the unit began tripping the breaker any time it went to the 2nd stage. Took them 3 days to come out (when approaching triple digit temperatures), charged $150 service fee and $450 in parts and labor to add a capacitor to the setup (a $50 part and about 10 minutes of labor). Did not fix the problem. Tech came out again, and said it seemed to be an issue with the breaker and that I needed to call an electrician to diagnose and solve the problem. Ended up paying $300 for an electrician to come out. When he took a look at the install, he was flabbergasted. He could not believe what he was seeing! He identified the unit was installed on an aluminum electrical line, that was severely undersized for the unit installed. He said no respectable company would EVER do this kind of shotty work. He said replacing the electrical line would likely cost a couple thousand dollars, since it was on the other side of the house. When I called Smart Air to let them know of the situation, the dispatcher was very dismissive. She said she would have their lead install tech follow up with me, but of course I never heard anything back... That is when they went dark despite several additional attempts on my part, and broke communication with me entirely. I ended up having to pay an electrician to run the new line on my own dollar - several thousand dollars - and now I'm finally back up and running.

I ask for a quote for maintenance on our units. They give me a price, a really good price. A price too good to be true. I ask why is it so cheap compared to other companies. They can't answer just say "these are our prices" I know our units are dirty as I just took over this place in January and we are yet to find a company to clean the units. So I schedule a day for the technician to come out and service the units.. They're up there for over an hour. They come down and I ask to go over everything They provide me 14 pages of diagnostics and ultimately tell me the units are dirty and we should schedule service request to clean them. I am upset at this point so I call to speak to the office and I get a guy in Florida who says he's with corporate and will look into it... Never hear back and I get an estimate of $4,400 to clean the units. That's insane! The company doesn't actively listen to what consumers need.

The few system repairs have been covered by the contract, including emergency service over summer weekends. The consistent excellent year round performance of our Carrier system has proven McCullough's annual maintenance fee to be a great value, with peace of mind. Most recently, Linel discovered rodent damage of our AC ducts. After exterminators resealed the house Ian was immediately sent by McCullough to repair the ducts reestablishing the sealed system. McCullough stands behind their warrantied installation, HVAC annual inspections and works effectively with other contractors. We strongly recommend McCullough's installation, maintenance contract, and reliable customer support.

The long Austin heat wave rolls on accompanied by the constant drone of my air conditioner. It is…read morenot a pleasant sound. It is the sound of money hemorrhaging from my household into Reliant Energy's bottomless maw. My house had issues. Let's just say that energy efficiency and green concerns were not at the top of the list when my cookie-cutter suburban pad was thrown together. My doors: permeable. My windows: radiant. My upstairs: a sweltering hotbox fit to slow roast a brisket to perfection. And onward droned the air conditioner. Now, before we go much further, I want you to know that I am not gullible. There are no magic solutions that would turn my house into a perfectly efficient icebox. It's bloody hot out there, and the relentless sun will have its due. I'm also not a wealthy man. I would not be swayed by some silver-tongued charlatan into undertaking a massive home renovation just to save some money on my electricity bill. I was looking for quick fixes for a fair price with tangible benefits (less hot air drafting into my house and less heating of my upper story from my attic). This is where the Energy Guys came in. I chatted with the owner (Jeff) as he was working on an insulation job for one my neighbors. I hate being sold to, so I was on guard for pressure sales tactics. Jeff was reasonable, factual, and laid-back. We did a walk-through of my house and came up with list of basic fixes. Thermal imaging confirmed what I suspected. My doors were leaking due to terrible weather-stripping, my upper story was baking due to poor insulation in my attic, and my duct work was poorly sealed with precious cold air leaking into my attic. Though I have windows that are just turrible, Jeff advised me that taking a second mortgage to replace them just didn't make sense for my house and situation. I've got two kids in daycare and a prodigious appetite for fine espresso, wine, and other edibles. There's not a lot of money sitting around to plow back into my house, but the bill was reasonable. The work should qualify for rebates offsetting a big portion of the cost, but that part hasn't been done yet. Jeff and his crew were professional, skilled, easy to work with, and punctual! My upstairs feels cooler, and I can't feel hot air seeping in from my front and back doors. Even better, there are now more frequent reprieves from the droning of the air conditioner. For anyone looking for an energy audit or other home energy services, these guys were great to work with. Highly recommended.

Mr. Wayne followed up weeks later for quality control and added more insulation and air sealing that was even more than what we had contracted for. I can't recommend Stellrr enough! This isn't a paid promotion or anything, I just think more people should contract with Stellrr and want to let people know that my experience with them was phenomenal. I recommend them 100%.
