We have been using B.C. Building Services as our go to Heating and Air Conditioning service…read moreproviders for 5 years. We tried Applewood and Lakeside previously and B.C. is hands down the best. They are very professional, always on time, have the best field service application for texting you when they are in route and invoice imediately while still on the premises a complete detail of the work performed. They do not try to up sell you on a new furnace or air conditioner like other unnamed providers do. Their tech's are always experienced. They are the best.

PS Cool Heat has been exceptional from start to finish. Our experience began with Josh, our…read moresalesperson, who was not only knowledgeable but genuinely kind. Yvette, who runs the office, was equally impressive--she answered every question we had and always responded promptly. The technicians were outstanding as well. We purchased our Highlands Ranch home in 2020, and since it was built in 2003, the original AC and furnace were long overdue for replacement. PS Cool Heat offered a very fair price on a new Lennox HVAC system. The dual‑stage air conditioner now cools our home within minutes--our old unit often took 45 minutes or more. This team is the real deal: professional, responsive, and truly pleasant to work with. Do yourself a favor and at least reach out to them. You won't be disappointed.

I'll start by saying that I waited over 2 weeks for someone to return my multiple emails and calls…read moreregarding this matter before posting this review but, to date, all have gone unanswered. I called Avalanche regarding my AC system not cooling effectively and when the technician arrived I was told that they could clean the units and add some refrigerant. I gave the approval to begin the work and when I came back out to ask about how things were going, I was told that they had to add SIX pounds of refrigerant to the first system and then was told it was $150 / lb. I immediately told them to STOP and asked why they would ever put that much refrigerant in a 'closed loop' system without checking for leaks. Jacob told me that it would be $2,200 to perform a leak check and that the leaks are always at the condensers which cannot be repaired. He then went on to provide me with a quote to replace the units which came out to over $22,000. (See pic) I reluctantly paid the invoice (see pic) and called another HVAC company for a second opinion and they were shocked at my experience. They reviewed the system and performed a leak analysis for $200 and ended up finding that a compression nut was loose and already had to add 1lb of refrigerant to the system (but at only $100/lb). Furthermore, they explained that my system COMPLETELY EMPTY only holds a little over 4lbs (see pic of unit tag) and a technician should never fill a completely empty system without checking for leaks. There's no possible way 6lbs of refrigerant could be charged into this system which was actually cooling our house to prior to their arrival. There's no question that I was ripped off here. I have a call into CDPHE regarding this negligence as well. Learn from my experience and call someone else such as ELKHORN.

Our AC went out during this July heatwave and of course it was on a Sunday night. I was able to…read moreschedule an appointment for Monday morning using their phone AI system. Super helpful not to have to wait for someone to call me back the next day to schedule. Got a price for the appointment at that time as well. And an immediate confirmation text of the appointment. On Monday morning we received a text message that they were on the way and the very nice technician Bo Holtz showed up on time. He was super helpful, immediately diagnosed the problem. Was super communicative and efficient. I know he was likely so busy too given the heatwave but he didn't rush he was through and provided amazing customer service from start to finish. He also suggested their monthly service plan and explained how that worked without seemingly like an upsell or hard sell. Just more a "hey, we have a great service plan if you're interested"...appreciate that. I also asked about an electric issue that we have been having with our clothes dryer and he was helpful pointing us in the right direction for an additional service tech from Aim High for that fix as well. Final price was exactly what we were quoted. PS sitting here in my cool 67 degree house as I type. Thanks Bo and Aim High!

From the immediate response to setting up the appointment (the office staff knew their stuff and was so polite), the on-time arrival of the knowledgeable and helpful tech (Travis) - everything was top-notch.

Chris was able to ask me some simple questions about our AC. I'm definitely the type of person to be like "please ask my husband" haha but Chris was super friendly and reassuring! Erfan was scheduled to come out after 5pm but thankfully he was able to come sooner in the afternoon! Chris was right - it was frozen! Erfan was so great!! He took the time to explain the process and all the charges associated with fixing our AC. Erfan was able to fix it and get everything working smoothly without any hiccups. Everyone at Behold Heating and Cooling was so kind and so helpful! Grateful they were able to fix our AC in this Colorado heat!

Come to find out we don't need a new heat pump at this time whereas he could have really pushed us to buy one. We were very impressed with his knowledge and professionalism. And will not hesitate to use Behold in the future. This was our first time to use this company. Also, Jay did not charge us for the couple hours he spent with us!

My mother-in-laws air conditioner was not working so I decided to call them for service on her nearly 40 year old system. Tristan came out and I truly expected the old proverbial "well this system is so old it needs to be replaced." To my surprise I didn't get that! Tristan had the problem diagnosed within a couple of minutes and showed me exactly what had happened and why the AC wasn't working. He was able to repair the unit with a new part and Did Not over-charge. I know how hard it is to find good help these days. I think all business owners struggle with this. I just want Mountain Air to realize they are in good hands and have a definite "keeper" with Tristan. He had a great attitude and represents Dan and team well! Many thanks and much appreciated!
