All reviews for Aether Mechanical, LLC

Aether Mechanical were outstanding. Really great patience and understanding upfront with all of the conversations and multiple rounds of estimating we put them through.
When it came to the day of install they were professional and efficient. Would recommend using them in the future. Big shout-out to Nico, Laramie and David.

We are so thankful we found Aether Mechanical. We live in Evergreen & our 20 year old boiler went out in November. We had no heat & a cold front was on the way. We called them & left a voice message on Saturday night, we had a call back Sunday morning & Nicholas was here on Monday morning to see what was going on. Their customer service was impeccable, they came out quickly, they were very professional, easy to work with, their pricing is very competitive & they presented us with several options for our budget. Their mechanical engineer, Nicholas explained everything to us & was the best, he is an owner as well. We decided to replace our old boiler & we could not be happier. We had the old boiler removed, a new boiler installed & it was ready to go in our home within 48 hours. Highly recommend Aether Mechanical, highly satisfied customer. Our home is once again warm & cozy. Thank you to Nicholas & his entire crew.

Nicolas and his team were fantastic! It took 2 business days from estimate to install of a fully functioning AC system. The job was done with care and they asked for my input along the way. Very professional!

We used Aether Mechanical HVAC to install a new boiler in our house in Wheat Ridge. Price, quality and customer service where top notch. I would used them again and recommend to all family and friends.

New boiler installation was completed in a professional and timely manner with great attention to the details. The system looks good and works beautifully!

I recently had a new boiler installed by Aether Mechanical LLC, and I couldn't be more pleased with the entire experience. From start to finish, the team was professional, knowledgeable, and efficient. They took the time to explain the options available to me, and they helped me choose the best model for my home. The installation itself was seamless – the technicians were punctual, clean, and worked quickly without compromising on quality.
What stood out the most was their attention to detail and willingness to answer any questions I had along the way. The new boiler has been running perfectly since installation, and my home is now more comfortable and energy-efficient.
I highly recommend Aether Mechanical LLC to anyone in need of boiler services. Their expertise and customer service are top-notch, and I'll certainly be calling them for any future HVAC needs.

This company came recommend by a friend had a representative come and gave us a quote he was honest and gave us a great fair price . They were able to have us scheduled fast and install was professional clean and fast. I Highly recommend this company.

Thank you Nicholas and team for your efforts, time and efficient response and installation & replacement of our 50 year old boiler. Nicholas discovered during fire-up testing that carbon monoxide levels were *way* above acceptable limits. We had a cracked firebox, necessitating replacement. In fact many cracks.
In spite of an expensive but necessary replacement, we are thankful to have it done as we didn’t know that it was omitting carbon monoxide. Nicholas was patient with me and answered my questions. Their team also corrected an incorrect error on our a new water heater that was installed in September by a different company. The technicians were friendly, on time and were here all day.
Thank you Aether Mechanical for your patience with me and for getting us up and running!

As an owner of a rental property, I am so happy to have hired Aether Mechanical to replace our aging furnace at our duplex. I had solicited three bids by the time a friend recommended them. They scheduled an appointment to meet with me soon after I called them. Nicholas met me promptly and he instantly impressed me with his knowledge, politeness, and professionalism. He knew all about my boiler system and recommended a new unit that would do the job efficiently (all other bids involved replacement of my old unit as well). Aether, which is a family-run company operated by Nicholas and his older brother Ivan, specializes in boilers; Nicholas recommended a Burham cast iron boiler that has a lifetime guarantee. Although Aether's bid came in somewhere in between the highest and lowest bids, I was so impressed with the company I decided to hire them, and as it turns out, I have absolutely no regrets. A job that is often done in two days was completed in one 10-hour day in order to make sure they didn't inconvenience our tenant any more than they had to. The company not only installs boilers, but they also provide other services (e.g., installing forced-air furnaces, mini-split refrigeration/heat pump systems, and tankless water heaters). My furnace at my home is nearing the end of its life (as well as my water heater) and I know exactly who I will call upon to replace them . It will be Aether Mechanical without reservation!

The quick review is that I highly recommend the team at Aether Mechanical. They are extremely professional, communication was great, pricing was very competitive, and the final product looks and works perfect. They are also very knowledgeable about HVAC.

I recently bought a mid-century home here in Denver that had a good looking American Standard furnace(Silver Series, 5 years old max) that worked well. The home inspection had no negative feedback on the unit.

Two months after moving in, we came home and there was a burning smell in the house. The furnace fan had burnt out. I contacted the team at Aether who scheduled a team member to come the next day and confirmed that the motor had burnt out and quoted me over $1000.00 for another motor- it would take 10 days to arrive with parts currently being backed up. The catch was that it was Mid-January in Denver, and it was like 20 degrees out. Nico at Aether mentioned that the original furnace had not been elevated off the ground on a box, and it appeared that it wasn't getting enough oxygen- perhaps that's why the motor burnt out- there was no guarantee that it would not burn out again in a year.

We looked into replacement options and I was given a very reasonable quote for another American Standard furnace with a full warranty. They would also install it on a box to give the unit plenty of air. They arrived the next day with the unit, installation took about 3 hours. I am very happy with their work on this!

Aether followed up in the coming days, and sent out a rep a week later to further calibrate the new furnace to the size of our home.

10 out of 10! Their team came to my house and were thorough, friendly and gave me a great price. I’d recommend them to everyone!

I recently hired Aether Mechanical to replace two old boilers in a historic 100 year old house in Park Hill. Nico was able to quickly diagnose the problem with my existing hot water heaters and boiler system. He came up with a great system that not only functions better but is highly efficient and saves on my monthly natural gas bill. The entire team is very professional and hard working. I highly recommend this company.

Aether mechanical did an Apartment complex heating system and water heater installation. They were very professional and thorough with their service. They explained everything in detail and provided photos of the work completed. We are pleased with their services and they come highly recommended.

Installed a Halo 5 whole house water purification system, amazing work and and amazing company. 100% recommended for any of your IAQ or HVAC work. Nico and his team are so professional and the work speaks for itself

I would like to thank Aether Mechanical, LLC for a complete diagnosis of my AC issues. Thank you to Nicholas and his crew that came out and made the necessary repairs in a timely manner. They were also very respectful and kept me informed the whole way until the very end of the project. Also thank you to Laramie for providing his expertise and explaining how everything worked. I highly recommend these guys.

My 30 year old boiler needed replacement. I contacted 3 reputable local Denver HVAC contractors for a quote on a high efficiency unit. One company stood out above all others. Nicolas from Aether was impressive with his boiler systems knowledge, and manner of explaining the options. He provided detailed pricing for 3 brands of boilers from good to best quality. His proposal was easy to understand and had much more reasonable pricing than the other contractors. He and his large crew were on schedule as promised and able to install the new boiler in one day. Compared to other contractors I have used for similar projects Aether's workmanship was the highest professional quality. I would recommend Aether above all other HVAC contractors.

Our old boiler had been giving us trouble for months, and my husband kept saying we’d probably have to replace the whole thing. I decided to get a second opinion and called these guys and wow, am I glad I did.

Their technician showed up on time, was super friendly, and immediately diagnosed the issue. Instead of pushing a costly replacement, they repaired the boiler quickly and saved us a ton of money. When my husband got home and saw everything working perfectly again, he couldn’t believe it. I told him it was all thanks to the new company I saw on Instagram.

It’s such a relief to find a company that’s honest, skilled, and doesn’t take advantage of people. I’ll be recommending them to everyone I know. Thank you, Aether Mechanical, for the great service and for making me look like the hero of the house.

I had an excellent experience with this company! Their service was outstanding from start to finish — very professional, attentive, and quick to respond to my needs. They took the time to explain everything clearly and made sure the work was done right.

What I appreciated the most was how approachable and bilingual the team was — making communication smooth and stress-free. It’s rare to find such a combination of great technical skill and customer care.

Highly recommended for anyone looking for reliable air conditioning and heating maintenance!

I can’t say enough good things about Aether Mechanical here in Denver. A few years ago, they literally saved my family’s life by discovering and fixing a dangerous carbon monoxide leak in our home. Their professionalism, attention to detail, and genuine care for our safety left a lasting impression.

Since that day, Aether Mechanical has been the only company we trust to work on our home. For the past three years, their team has handled everything with honesty, expertise, and top-notch service. It’s rare to find a company that truly cares about their customers like this one does.

If you want reliable, trustworthy, and skilled HVAC professionals who treat you like family — look no further than Aether Mechanical. They’ve earned our complete trust and deepest gratitude.

Absolutely Blown Away by Aether Mechanical!

I recently used Aether Mechanical for the first time, and I’m honestly kicking myself for not calling them sooner! From start to finish, they were professional, punctual, and incredibly knowledgeable. They explained everything clearly and didn’t try to upsell me on anything I didn’t need, which is rare these days.

Their prices were more than fair, especially considering the level of service and care they provide. You can tell they genuinely take pride in their work and want their customers to feel taken care of. My system is running better than ever, and I finally feel confident that I’ve found a company I can rely on for years to come.

If you’re looking for an honest, affordable, and dependable HVAC company in Denver, Aether Mechanical is the real deal. I can’t recommend them enough!

We had them install an LG mini split system five years ago — 18 indoor units and 4 outdoor units. The work was professional and efficient. They’ve handled all the maintenance since then and have always been reliable.

They also have the expertise to fix issues with older LG systems. Great team, great service — highly recommended!
