1524 Collyer St, Longmont“This is an outstanding HVAC solutions provider!
In order to sell my 21 year old townhome with original equipment, I shopped three firms to help me replace old equipment: Colorado’s Finest beat the pants off the other two, in terms of service, attitude and Value.
They care. They’re highly professional. They’re efficient. They are honest. They are timely.
This company gives the industry a great reputation where other firms game play, deceive and possibly leave a customer with bad impressions.
I recommend them to you, your family and friends, and work colleagues seeking HVAC solutions.“

1831 Boston Ave, Longmont“I’ve used Welzig for a variety of services and have been incredibly impressed every single time. Most recently, I had their electrical team—Paul and his two apprentices—install conduit for my EV plug. While doing the job, they discovered that my ground wire wasn’t actually in the ground (a major safety issue I never would have known about). They fixed that right away and also installed a surge protector for extra peace of mind. Their attention to detail and commitment to doing things right really stood out.
I also had Johnnie come out to install a Halo water filtration system, and I absolutely love it! The water quality is amazing—it completely eliminated the chlorine, which is a huge relief for my autoimmune and other health issues. It’s made a noticeable difference already.
On top of that, I’ve now signed up for Welzig to handle all my ongoing maintenance needs for my furnace, AC, and tankless water heater. They’ve already done this year’s service, and everything is running smoothly.
From electrical to plumbing to HVAC, Welzig is my go-to. I trust them completely. They’re responsive, professional, and just great guys all around. Highly recommend!“

810 1st Street, Firestone“Kevin Baker was very professional and friendly when he came for my air conditioner checkup. He explained everything he was doing and answered all my questions. I would definitely recommend Kevin if you are needing service on your air conditioner or furnace. I will definitely be asking for Kevin the next time I need service! Very happy with Kevin and Carbon Valley!“

500 9th Ave #12, Longmont“If you're sweating to death in your house because your AC died and you've been told you have to get everything replaced to the tune of about twenty grand, but you don't know a single thing about HVAC installs and are concerned about some nefarious company screwing you over—
Relax. You've found the right place. Bob and his crew are excellent—and they're honest. Liz in reception is very nice. I got estimates from multiple places and even though I hadn't yet signed a contract with Circulating Air, Bob took the time to explain to me why the other bids (from Cooper and DNI) were actually terrible. It turned out they were offering me about 25% less for 25% more.
The install took less than a day. When I had a problem with the AC keeping the house cool, they promptly came out and fixed it (turns out it was a manufacturer instruction error about how much refrigerant to add.)
It is stressful when you're about to drop 18K on a big project—particularly if you don't know anything about HVAC and are ripe for being ripped off.
Go with Circulating Air. You won't be sorry. Also, if you're contemplating going with a place that offers financing, don't. Try to get a HELOC or other sort of bank loan. It ends up being cheaper.
Thank you, Circulating Air!“

338 Main St Ste 14, Longmont“Colorado Green Plumbing is amazing. Not only did the technician walk me through what the issue was, he did not choose the most expensive method to fix the issue, he started small and the fix worked. This is like the old days were the folks showed up on time, you could trust them and they wanted your business for life, not just for a short term profit!“

727 Main St, Longmont“It is a great feeling when you need HVAC work done and when the work is completed it not only exceeds expectations but is done at a very fair price. Home Run HVAC and plumbing has done exactly what their name implies; they have hit a 5 Star home run for some very difficult work in my 118 year old home. Highly recommend giving them a call if you are looking for help with heating, cooling or plumbing, you will be very happy if you do.“

He did a thorough evaluation of my new home, checking the sump pump, water heater, pipes, toilets, and test my water quality. He identified that my water had extremely high levels of chlorine. Very affordable and educational“

4007 S Lincoln Ave STE 440, Loveland“They quickly identified the root of my problem and fixed it. But what I appreciated the most was their willingness to explain how things worked enough for me to troubleshoot some common problems on my own in the future. As a first time home owner this meant a lot. If I do have another problem I can't solve though, I'll be calling them for sure. Quick to schedule and more than fair with rates too.“

5400 N Garfield Ave, Loveland“Anthony was everything you want and expect from a service tech. Really knew his stuff. The repair was absolutely non-trivial and it took most of the day. He took the fan unit to a car wash to make it absolutely as clean as possible. I call that above and beyond my expectations. The end result was a successful repair, heat was restored. He is a very personable young man.“

5411 Wolf St, Longmont“Corey and Vertical Heating&Cooling are simply unbelievable! One of our two water heaters was flooding into the crawl space along with flooding from a water line. The two were not related but created a giant mess. Corey responded right away. Reorganized his schedule for our emergency! Corey not only replaced the ruined duct, but called a water restoration company for us. Repiped and Installed a tankless heater, and did a maintenance check on our HVAC. When nobody would respond to our emergency, they were here within two hours. Their cost was very fair and their professionalism was off the charts! I highly recommend Vertical Heating and Cooling!“

We did a full renovation on our house in Commerce City and ended up replacing all our HVAC ducting and replacing our furnace with a high efficiency unit. Ryan came out and gave us a very competitive quote that was professional and comprehensive. The crew that completed the project was efficient, polite and knowledgeable.

308 Mountain Vw Rd E, Berthoud“I am 100% satisfied with my experience with Ideal Comfort! There will always be a back-and-forth when negotiating terms and researching the product, or a missed email or call when it is a big job and so many people are involved. The folks at Ideal Comfort are human! Give them some grace and keep following-up if necessary. Ben was excellent at answering all my questions and he was present on the day of the install. The installers were nice, neat and professional, and quickly corrected a mistake they made without hesitation. The product is high-quality and working as expected 3 months in. And then Sarah managed the rebate process (I literally did nothing but answer a few of her questions) and I got a check in the mail from Xcel! I highly recommend this company and would use them again.“
