One of our heat pumps broke down during the hottest part of July. I called several companies and Efficient was the first to call back. They were able to get a technician out later that day. The bill ended up being much less than expected. While he was here the technician (Ernest) noticed that we had condensation from the A/C dripping secondary drain lines under the eaves. He checked the air handlers inside the house, replaced the air filters, and cleared the clogged primary condensation drains. We ended up buying a maintenance contract so we can have them come out later this year and make sure that everything is working well at no additional charge. Overall, I was very pleased with their responsiveness, the work they performed, and the price charged. We will use them again and I would definitely recommend them to others. read more

They have been maintaining our small commercial building for years and have always done a great job. They show up on time, are fair with pecking, & always get the job done. They even came out on Saturday to help us out! read more

Efficient installed two new units in our house in 2013, and did a great job. We also signed up for twice a year preventive maintenance checks. But they failed in that regard. We discovered mold in the 4-ton unit that was due to failure in the return air plenum that allowed warm ambient air into the system. We contacted Efficient and showed them the pictures of the mold and the plenum failure after we had the system re-mediated.The remediation and repair cost us over $8,000.00 and Efficient, after exchanging numerous emails and stopping communicating with us, has failed to offer any meaningful remuneration. We paid for preventive maintenance and they failed us. We will have to look for an honest HVAC company. read more

These guys are awesome. Had one of my units out. Jeff promptly responded, made a temporary repair, and diagnosed a leaking coil. I got 2 other estimates and Efficient was reasonable and they made an effective repair. This by itself would not earn five stars. Saturday evening on Labor Day weekend the other AC is out and it's 100 degrees! I call their number and Tony promptly responds. He explains emergency service is $15 more per hour. Ok, that's pretty reasonable. He is at my house 30 min later, replaces bad capacitor and I'm up and running literally 90 min after I called. Labor Day weekend. Extra $15. Five Stars. read more

I recently used 911 Electric to un install two chandeliers in my boss' home. He has already moved and I am on a very short time frame to get everything out of the house. 911 was great to schedule me quickly, arrived on time and Jason & Jeff were both very professional! They charged exactly what was quoted and left the home without any evidence they had ever been there. I definitely recommend 911 Electric if you need an electrician in the Austin area!! read more

Best AC company in Austin. Their employees beginning with the receptionist are the kindest folks! I have worked with Darwin twice and he is very knowledgeable, patient, kind and extremely helpful! I highly recommend Efficient AC to everyone! read more

I had a leak coming through my ceiling. Shutoff valve was corroded and I could not turn off the water. My wife called Efficient AC , Dallas and Eddie were here in 20 minutes... They turned my water off and identified where the leak was coming from. Top notch response, they could have not been nicer and more professional! read more

We have a geothermal A/C in Lake Austin. Tony is terrific and maintenance and repair. Always on time, efficient, and fixes the problem or routine maintenance. read more

Just had my AC go out last night. Called during lunch and left a message for the scheduler, Michelle, who called me back right when she returned! Dispatched Jeff to come out and he reviewed our issue. We were worried there were large issues, but he fixed it and only charged us the service fee and some labor. Jeff was straight forward and honest! Definitely recommend! read more

Quick and efficient service, and didn't have to book to far in advance to get a summer AC appointment. The office staff was very good to get me set up with an AC tech and electrician to come at relatively the same time. One of the techs did get lost and was a bit late, but was in contact with me and the service was quick once they got here. Both techs were very friendly. read more

Service calls are always a nail biting experience. But Efficient Air Conditioning sure lived up to their name. I called them in the morning to come have a look at my non-working air conditioning and they promised to be out that afternoon. Sure enough, I got my status call letting me know they were 30 minutes away from being at my front door. Again, how nice is that? Two fellas turned up, had a look and let us know it was just a tripped fuse in the attic and fixed it and were out of there within 30 minutes. Now the air is working and I can breathe easy. I recommend them!!! read more

Did several electrical jobs around our new home. Super friendly, great work. Definitely recommend and would use again.

Courteous and knowledgeable technicians. Great and efficient work, what else can you ask for...Highly recommend!

I am shopping for a new H/VAC system, which reminded me to write this review about the work they did for me several months back. I will not be using Efficient for any future work on my H/VAC and here's why: Back in August, my A/C was working and not working (i.e,, coming on sometimes, but not always). I called Efficient and they sent a nice tech out to diagnose the problem. He diagnosed it as a low performing capacitor. Replaced it at a cost of $260. The unit cut on after he replaced it so I figured he knew what he was talking about. Later in the day though, the same problem occurred. I called Efficient and they sent the tech out next morning. This time he told me it was the motor. Cost: 600+!!! Well, it's August, I'm boiling, I stupidly fell for it. The unit worked okay for about a week and then the same problem presented again! Same exact problem - sometimes cutting on; sometimes not. I started doing some research online and everything I looked at suggested the problem might be the relay switch. But who was I to tell that to a professional? LOL Efficient sent out a tech who diagnosed.....what else but a broken relay switch. He replaced that and to Efficient's credit, at no charge. (Had they charged me for it, they would have received a one star review). So turns out the relay switch was the problem and the A/C worked fine from that point on. However, I ended up spending way more than I should have (i.e., almost $1000). The relay switch, if it had been properly diagnosed in the first place, would have cost much less. That's why we call professionals --- to properly diagnose and fix a problem, not to just keep replacing things until something works. read more

My A/C died while I was deployed to Afghanistan, the entire staff at Efficient A/C did an outstanding job and making what could have been a highly stressfull stituation very easy. From the company president to the sales manager to the service tech and the installation crew they all were extremely professional and attentive. Even with the time difference I was able through email to get all the details worked out and have a new system installed in just a matter of days! They truly lived up to their name! read more

My house utilizes ThermalFlow HVAC system. The manufacturer installed the system but provided very poor service and support post installation. I struggled with this for 4 years until I got a referral to Robert Lee at Effiicient Air. Robert and his team came in and clean up the system, installed a professional monitoring system, and made that system work effortlessly through 2 long hot summers and an extremely cold winter in 2010. Robert's is on top of all the latest energy saving technologies and his crew is prompt and professional. I want to thank Robert and his crew for their work and will recommend them highly. read more

Super happy with all they have done for my family. I had another HVAC company come out to look at my system and they told me I needed a new blower and a new control panel. No service fee for the evaluation, but extremely over quoted replacement parts and labor. Spoke with Michelle at Efficient A/C & Electric and she was extremely helpful, worked with me to get a technician out for an evaluation the same day. The technician confirmed that I did NOT need a new blower and talked with us about a resolution that was best for us, rather than what makes his company the most money. Very impressed and will always use Efficient A/C & Electric in the future! read more

Efficient was the first (after MANY phone calls) to quickly respond to us and keep us posted about when they'd be at our house. We purchased 2 hours of service to determine some outlet problems, but he finished quickly (even having to move heavy book cases that had been bolted to the wall) and credited us for the extra time. We are very happy with the service! read more

Called Efficient A/C at end of day (430pm) for my home a/c not working. When other competitors had all said they couldnt come until the next day, Efficient A/C having good reviews on various websites said "Let us check, maybe we can get their today." They checked and in 30 minutes they were at my house fixing the issue (around 5pm+). They took lots of questions from me, lots of suggestions from me and did so in a friendly and informative manner. They were upfront with the pricing and how their pricing/charges work. In the end the price to replace my capacitor was $300 for labor and parts. Might be a little high but this higher(?) price was justified given the capacitor they used is made in USA and comes with 5 year warranty (higher quality I would hope and think). Glad to see it wasnt made in China or Mexico due to lower quality of such manufacturing sites. The good service was also worth the higher price as was their speedy response. The repairman's name was Robert Whitaker and he just did a great job of customer service and repair. read more

Needed a new A/C and Furnace replaced ASAP, contacted three local companies and found Efficient Air Conditioning to be the most responsive and competitive in pricing. Darwin came out and did the estimate, even showed up early for the appointment - very knowledgeable and professional. He understood the urgency and was able to schedule a total system replacement within just a couple of days (after I'm sure much juggling of backlog given the weather and demand.) I had some follow-up questions via email and again, Darwin responded quickly and professionally. The crew he sent out was top notch, arrived on time and got the job done in a day - no fuss, no mess - all around just a fantastic effort. The new system install comes with a 2-year labor warranty from Efficient, which combined with the manufacture's product warranty gives me assurance that the AC and heater will run smoothly for years to come. Darwin also took care of the energy rebate and advised on the tax credit that comes with a 16-SEER system. I would highly recommend this company to anyone who may need their service. Thanks Darwin and the crew for the outstanding service and support!! read more
