Why We Cost Less
We're not the official sponsor of the Broncos, the Nuggets or the Avalanche. We're the official sponsor of not taking your money for professional sponsorships.
Big home-service companies here sponsor the Broncos, the Rockies, the Avalanche, and even Denver's new pro soccer team. Stadium signs, Zamboni ads and game-day giveaways aren't free. That money comes from somewhere: your bill.
Ours stays in Colorado and helps us provide for our families, not investors across the country.

What Customers Say
“If you’re looking for an HVAC company that treats you like just another job, keep scrolling.
From the first day, Second Opinion impressed us with their professionalism, honesty, and incredible attention to detail. John, Lefty, and Michael did not just install a new Mitsubishi Intelli-HEAT system. They engineered a complete comfort solution for our home, including a new cold-climate heat pump, heat pump water heater, and all of the supporting work needed to make everything function as designed. Every aspect, from system sizing to airflow, duct modifications, refrigerant lines, controls, and final commissioning, reflected craftsmanship and pride in their work.

What stood out most was their commitment to getting everything right. During startup, they encountered an unusual configuration issue involving a Mitsubishi branch box. Rather than guessing or cutting corners, they worked directly with Mitsubishi’s field support until they had the correct answer. Within minutes of identifying the issue, the system was operating exactly as designed. That level of professionalism is rare.
Throughout the entire project, they answered every question, explained what they were doing, respected our home, and never made us feel rushed. They genuinely cared about the outcome, not just finishing the installation.
Since the installation, we have already experienced several days with temperatures exceeding 100°F. While it has felt like the middle of summer outside, our home has felt like fall. The system has kept our house consistently cool, comfortable, and remarkably quiet. It has exceeded our expectations.
Beyond the equipment, what we will remember most is how we were treated. We were not treated like customers. We were treated like family.
If you value expertise, integrity, and people who stand behind their work, I cannot recommend Second Opinion highly enough. Thank you, John, Lefty, Michael, and everyone at Second Opinion for going above and beyond. Five stars simply are not enough.”
“I am so glad I found 2nd Opinion.
Our furnace and AC were reaching end of life and I wanted to take advantage of rebates and tax credits before they expired. I contacted a couple different HVAC companies for quotes.

The first company showed up and spent about 5 minutes assessing our HVAC system before leaving and emailing me an estimate later that day with no explanation of the work to be done or what our trade-offs might be.
When 2nd Opinion came over, they assessed our entire system, including the volume of each room and where our vents are located. They also asked about the history of the house and our plans for the future.
I’m so thankful they went into the level of detail they did. We were able to right-size our HVAC for optimal performance. They walked me through the benefits of different systems (gas, electric, filtration options). They went above and beyond in their installation, explaining their work and presenting us with options when available. They did not push or upsell, they told me what they would personally do in our situation, but also made recommendations based on our budget.
What’s better, the team helped me navigate the energy rebates with both Xcel and the state. They even applied the rebates directly to my invoice and took care of the paperwork themselves.
2nd Opinion’s quote was more than the first company’s quote, but for obvious reasons. I really got what I paid for - and more. Amazing service and the confidence that the job was done right. Highly, highly recommend!”
“After getting an astronomically high quote from a local company, I called 2nd Opinion for an estimate. John was generous with his time and explained a few things to me.
A technician came out and fixed our AC perfectly. Communication was quick, clear, and pleasant. I would 100% recommend working with 2nd Opinion.”
“They examined my broken furnace, presented all the options I had available, gave me honest opinions on fixing it or installing a new one, got me exactly what I needed without trying to upsell, promptly installed it, gave a follow up and it has been perfect since.
Great price, amazing service, wonderful customer support.

Already looking to them again on getting a heat pump and again they have been great showing me all the rebates I'm qualified for and giving me estimates without any hard pressure sales.
Will definitely use them again for all my needs in the future.”
“My experience with John was beyond excellent. He is professional, very knowledgeable and experienced and honest. He came to assess my potential for upgrades and rebates and upon hearing my concern for adding more waste to our environment, immediately pivoted and offered me solutions for maintaining my current furnace. I will definitely hire him when the time comes for a replacement. It is wonderful to encounter such integrity. Highly recommend.”
“We’d gotten three very different quotes from HVAC companies and were feeling pretty overwhelmed. Then we reached out to 2nd Opinion and wow—so glad we did. Their price was literally less than half of what some of the bigger companies wanted to charge. Plus, John actually took the time to walk through our home and make sure we got the right-sized system (the others were pushing way bigger ones we didn’t need). On top of that, they helped us tap into Xcel rebates and state tax credits that knocked more than $5,000 off the total. Super honest, professional, and saved us a ton—highly recommend if anyone’s shopping around.”
Small enough to care, big enough to back it up.
