HVAC reviews in Aurora, Colorado

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!

Aether Mechanical came out to give me an estimate for my AC unit and I couldn’t be happier with the experience. Super professional, on time, and easy to communicate with from the start. Liam walked me through what he was seeing, explained my options in a way that actually made sense, and didn’t try to upsell me or pressure me into anything.

The estimate was clear, detailed, and fair, and Nico answered all my questions without rushing. If you want an HVAC company that’s honest, knowledgeable, and treats you with respect, I’d absolutely recommend Aether Mechanical

I’m going to be objective about this and you can make your own decision. We need a new boiler within the next 5 years. We decided to start looking into engineering companies to explore our options. Nicolas arrived timely and within short notice. He seemed so knowledgeable, and I was impressed. Despite trusting our current company, we decided to try out Aether to see what we thought of them for our boiler replacement by turning on our boilers this season. They were more affordable and Nicolas is a reported engineer although you cannot find him as a licensed engineer in DORA. Other engineers we have explored are licensed in DORA. We have two boilers. After arriving to work on our boilers with another guy, Nicolas called me and showed me the boiler lighting up more than it should on startup bc of a gas problem. He immediately said we needed a new boiler. A new boiler for us costs between 57k to 70k based on Nicolas’ 3 estimates. This actually seems correct compared to prior data we have. What concerned me is such an immediate conclusion of needing a whole new boiler. Our boiler was fine at shut down in May. I suggested why not replace the gas regulator and see if that would work. Seems reasonable if too much gas is coming out. Nicolas then said that it would be possible to look into. I left. Struck me as odd that I had to suggest that. Maybe an hour later he contacted me and said that he tested the gas pressure on the regulator unit or whatever and the pressure was correct. The only thing it could be was a crack in one of the burners, necessitating a new boiler. He put a red tag on it, shut it down, and said this was a very unsafe situation. He also went and turned on our other boiler. Again, another call. Our reset button on the low water cut off was broken and we needed to replace the part. Also, something was wonky with the electrical wires so they fixed that, but we needed to do something with that too. He also alleged that our last company must have cut this wire thing with the other cut off part that he quickly found lying on the side of the boiler. He said there was no way that our boiler could operate with that. It had to be the last boiler company. He pointed out the clear cut the company must have made in the component. More money. Two days later, our original, trusted boiler company came out for a second opinion. They reattached the “cut part” that was removed from where it should have been. They did several other things. Boiler is up and running. He pulled out all the burners. No cracks. Fixed for around 1k vs 57-70k! Also, having used our original boiler company for last year’s turn on and shut off as well as repairs, they are quite familiar with our boilers. I had them look at the low water cut off. They reported it has been rewired, causing it to bypass the cut off. They fixed the wiring, and it is suddenly working, again! This was the low water cut off is for SAFETY by the way. No replacement needed. I wonder what Aether was doing with the wires. Would you? We were supposed to have a meeting with Nicolas the next day, as it’s October and we need heat. I sent him a very objective email about how our boiler was fixed and the wires were bypassed. I shared a nice video of our beautifully burning boiler that was fixed and safe. I cancelled our meeting. He texted and called me the same day. I ignored it. This is factual, objective information. You make your own inferences given this information. I don’t know how you can rationalize this any other way than what is clear here. Everyone is safe and cozy tonight with heat is still in the building with the supposedly irreparably “broken” boiler. First video…a video Nicolas sent of our “broken” and “unsafe” boiler needing replacement. You can clearly hear his voice in the background towards the end. Enjoy the whole video! Second video two days later…looks like a safe burning boiler to me!

Nico and crew were great installing our Navien boiler. So good in fact, that I had them do our gas furnace as well. Couldn't have been more professional. We've had no problems with either one and it's been 2 - 3 years. Nico explained the importance of regular maintenance, so we did it. No more worrying if something going to fail. We wouldn't call anyone else. Very fair/reasonable pricing...and honest - and more than than that cannot ask.

We were at a loss before finding Aether Mechanical! We had a combi boiler that was very loud, it sounded like it wanted to blow up, it never properly worked. We did not want to call the original installer, we were done spending good money on a bad situation. Fortunately, we found Aether Mechanical (a God send). On Wednesday, Dec 3rd, Nico and Louis came into our home. They looked at our Lochinvar boiler and told us immediately it was connected backwards. Turns out the entire boiler was bad due to poor installation. On Thursday, Dec 4th, Nico and his amazing team, put a new Navien combi boiler with all new parts and piping. They were extremely professional, clean, efficient, new combi boiler in one day!! This boiler is amazing!!! The house is warm, the hot water is hot, no loud noises, no low flame lock outs and the house is comfortable, quiet, and we feel very confident this new Navien system is what we needed. They also have interest free financing. This is the only company we would recommend for your Boiler, HVAC, and Furnace needs!! Thank you Aether Mechanical. So grateful we found you! You will never go wrong with Aether Mechanical, they are the best!!

Can’t say enough about this company! Nicolas, the owner, came out and diagnosed my furnace system after I noticed it acting finicky. He spent over an hour conducting rigorous testing, explaining every piece of my system and how it works, and trying to find the best solution for our home. Unfortunately, the furnace was not able to be saved as it was damaged and an active fire hazard. Nicolas presented several options to me for purchasing a new furnace, explaining the pros and cons of each, and was honest with what my home did/didn’t need from a new system in terms of efficiency and power. Aether’s offerings were not just cheaper, they were at least 10k lower than the other quotes we’ve gotten from some of the big name HVAC competition in Denver! Not to mention their warranty coverage and included servicing was unmatched, and they went out of their way to find the most convenient payment options for us. It was an easy yes.

All the necessary parts and the unit itself were in stock, so we were able to install the next morning. Laramie and Liam were prompt, kind, and got right to work. They even went above and beyond to clean out the central duct to the best of their ability, which had been clogged from years of deferred maintenance by the previous homeowners. They left the furnace area cleaner than they found it, and went through all the necessary details with me to make sure I didn’t have any remaining questions before leaving the home.

Our home is warmer, cozier, and safer than it has ever been! We will definitely be calling them again.

Ben and Leo were our install team. Paul N. was our comfort advisor. The whole team was very knowledgeable, efficient and did an excellent attic furnace installation. They cleaned up very nicely after the installation.

The team at ARS Rescue Rooter did a great job at communicating with me in regards to scheduling prior to sending Plumbing Service Technician Lance McCartney to my residence to handle my drainage problem he was punctual, polite, extremely professional and knowledgeable I would recommend this team to anyone in need.

The technician was really knowledgeable & explained what was wrong with my furnace in great detail. He was extremely nice. He was great. I recommend this company.
