All reviews for Aether Mechanical, LLC

Technician was on time, professional and friendly. He walked me through the process and finished the work efficiently. I highly recommend their service.

Highest recommendation for the Aether Mechanical team for our recent boiler replacement--every detail of the experience was managed professionally and expeditiously, and the entire project was completed in one day. Take a bow Nicholas, Ivan, John, and team--virtuoso performance and a first-rate result!

Two days after Christmas we woke up to a cold house and a boiler that would not fire up. Aether Mechanical responded at once by phone and Nicholas arrived onsite from Boulder to our house in SE Denver within two hours. Initial assessment indicated a burnt-out igniter. Nicholas replaced that and discovered during fire-up testing that carbon monoxide levels were *way* above acceptable limits. After repeated tests, the unavoidable conclusion was a cracked firebox, necessitating replacement. We reviewed estimates at three price points, selected one, and Nicholas mobilized his team. During a holiday week, working around challenges with HVAC supply house business hours, the team completed the installation entirely the following day.

In spite of an expensive but necessary replacement, this has been singularly the best contractor experience I have had in 25 years living in a mid-century modern house that is starting to require more frequent repairs.

The Aether Mechanical team was great! They gave me several options in repairing/replacing my heating system. Their pricing was more than fair and the install team was fantastic. They even went above and beyond to educate me. Highly recommend this team. Thanks guys!

These guys know what they’re doing. Ivan got me on the schedule in a very timely manner before the cold weather hits. Paolo and Laramie arrived on time and performed a very professional mini-split installation. Looks and runs great. Thank you.

I highly recommend Aether Mechanical! I had a new furnace and AC unit installed and they were great to work with. They provided multiple quotes to fit my needs and offered very competitive pricing. The crew and owner were polite and answered all of my 12,475 questions. :)

I needed ventilation installed for a commercial coffee roaster and it took me probably 20-30 phone calls to various HVAC and mechanical contractors before I found someone who would take on the job. Aether came to the rescue!

Aether and their team (Nicholas, Ivan, and Robby) were incredible from start to finish.

This was the first time they had ever installed ventilation for a coffee roaster but they knew all the right questions to ask and miraculously found the parts locally (which is almost impossible). They really went above and beyond to finish the job

Overall, I found them courteous, professional, and extremely competent.

Would definitely recommend!

Great experience! Very professional, transparent about the whole process, and offered competitive pricing.

We had a great experience with Ivan and Nicholas and the team at Aether. They were communicative, punctual and gave us great service with our new minisplit. Highly recommended!

Amazing experience, Pilot fails on unit. Tech came out and assessed the issue amazingly within 5 to 10 minutes. Gave me a great quote and fix the problem in less than an hour, without trying to sell me anything more than what I needed done! If you’re in need of a great HVAC company look no further! Thanks again for the amazing service!

We had a new boiler system installed in our home December 23’. For sixteen months our system just was not operating correctly. We had the great fortune of finding Aether Mechanical LLC. Nicholas, Paolo and Ivan were the “BEST”!! From our initial meeting with Nicholas our experience with this company was “seamless”. Aether updated our system, adding updated equipment that should have been installed from the beginning. I did a bit of background exploration because of having been so disappointed by other companies, financially and emotionally. Nicholas has a Mechanical Engineering degree from Colorado school of Mines. Nicholas came into our home and (no exaggeration) in two minutes he diagnosed our initial problem. He explained in detail, that we were able to understand concerning the outdated parts of our existing system that needed to be replaced. Thank you Aether for giving two old guys great service and FINALLY, PEACE of MIND. Great business experience.

Called Aether for a HVAC inspection prior to listing our home for sale. Nico and his team were friendly, professional and did a thorough inspection of our system. They did find a couple tune up issues, his recommended fixes (valve replacement/exhaust repair) were done well and Nico explained how it might affect a home inspection if those weren't resolved. Aether provided great service and I wouldn't hesitate to hire them again.

Nicolas was amazing! I talked to 3 different hvac companies and he was the best. He took his time explaining everything during the first assessment and then did the same during installation. The whole process was very smooth and I would highly recommend them to anyone. Will definitely be using them again if needed in the future.

They did a great job. With the new install. I’d use them again.

Great job installing new furnace and thermostat. Big thank you to David, Paul, and Louis!!

Nicolas and his team did a great job. They responded quickly to my inquiry when our A/C when out in 90+ weather. Nicolas walked me through the different options we had and made me feel comfortable making a decision. The work, price, and quality of service was outstanding. Will definitely be using them again in the future for all our HVAC needs.

There was a leak in the wall of our powder room the Friday before Christmas, we gave Aether a call and they were able to send Nico and Ivan over the same day. They diagnosed the issue and where the leak was coming from so there was minimal damage to our drywall. It turns out there were two pinhole leaks in each pipe to our bathroom sink but Aether was able to repair the pipes with thicker copper and explained why the leaking pipe wasn't the proper type. Really grateful they were able to come out on short notice before the holiday! Great guys that provide great service at a great price!

I used them twice, both in early December 2023 when my 20+ year old gas furnace stopped working and this past April when I wanted to reconnect my 10+ year AC unit but the older RU22 refrigerant made it incompatible with the newer furnace system. Both times, the technicians were very responsive, came out quickly to diagnose the problem, and were able to install within a few days of requesting a replacement. Their prices are reasonable and comparable in the market (I had done some quotes with other contractors a year before in anticipation of the system breaking down so I was able to compare before accepting their quotes). The technicians were very professional and knowledgable. My new heating and cooling system is running much more efficiently than before.

We experienced that homeowner horror recently - oh no, our 30 year old boiler failed! After a bit of online research, we asked Aether Mechanical to come by, check everything out, give us recommendations. From the first moment we met Nicholas, we knew we were in good hands. It's nice when the owner of the company (even if it's a small company) comes to meet a potential customer for the first time, and then you find out that he has a Masters degree from Mines! He was very polite, patient in explaining everything that had happened with our old boiler, also patient and not pushy when presenting us with options for a new boiler, including the financing options. We decided to go with one of the options he presented, including the financing, which went through quickly and easily, and the deal was done. Within a couple of days the work began and it was seamless for us. Nick and his assistant did everything they promised, again patiently explaining all the work they were doing as they were doing it. They thoroughly checked every aspect of the new system after it was installed to assure that all was working properly, showed us the new electronic components and how to use them, and left us feeling totally confident in our choice of our system, and especially in our choice of Aether Mechanical. I would absolutely recommend these guys with no hesitation whatsoever!

Excellent service, super-nice and very responsive! Our heater made some odd noises and Aether was there the next morning (and would’ve come out earlier if we had no heat). They diagnosed the problem thoroughly and made solid recommendations for fixing or replacing, and then replaced the same day!

Paul did an AWESOME job. Replaced a kitchen faucet. He was on time, professional, clean, and worked quickly.

We recently had installation done by Aether Mechanical, we had three other quotes from separate companies

The price and care that we received blew the other companies out of the water
