After all is said and done, I wish I had called Mountain Air first. If I would have contacted Mountain Air, this would have saved me 4.5 weeks of grief dealing with other companies who were disorganized, unable to keep appointments and would only show up to work a partial day. Yes, I was kept on the hook by other companies for that long with empty promises of we will be there today, tomorrow, next Wednesday...then they would not show up... or call to say they had to move the date. At one time I had 3 appointments by 3 different companies in a single week just hoping that one of them would show up that week. My situation was bad, I purchased a foreclosed house which was supposedly winterized which we later found out to not be accurate. The house had over 19 pipe breaks in the radiant heat system that had to be repaired before the Boiler could be worked on. However, my experience with Mountain Air went like this. I called Mountain Air on a Tuesday, December 13th 2016 at 5:15 p.m after yet another plumbing company could not make it and spoke with Cris, who told me that it was after hours and she was not in the office, but would call me back in the morning to setup an appointment. Wednesday morning I spoke with Cris and explained my history and I needed a plumber for a full day to fix all these breaks. She set me up with an appointment for the following Monday. However, on Thursday morning she called back and said she had an opening on Friday and would I like to have them stop by. ( Heck yes I would! , as this weekend it was going to be a -8 on Saturday and I was getting stressed about things freezing ) Thursday night, I got a phone call from the Tech Michael Stahl checking in to make sure he understood what was needed for the next day and if he should pick up any special parts. Then on Friday morning, he was on the job site at 8:05 a.m. ready to work. Yes.. that is not a typo error! He was on time and ready to go, unlike his competitors who would show up at 10:45 and 3:30 and leave in 2 hours Michael stayed until 6:30 p.m that night ( no lunch breaks ) and was able to get 5 out of 6 zones repaired and then fired up the boiler and got heat in that house before the cold front hit the next day. On Monday he came back and finished the last zone and then last night ( Wednesday ) he added Glycol to the system to protect my pipes from cold in the future. The office manager Azalia ? was kind and kept me in the loop as to the status of things. Other notable mentions: Michael came back and replaced zone valves and cleaned up the wiring so it looked professional and organized. ( I liked that too ! ) As you can tell, I am very pleased with how quickly things were repaired and how I felt like a customer. I totally "get it " why this company has 5 star rating.

Jordan took the time to explain everything clearly, answered all of our questions, and made sure we felt comfortable with the entire process. The crew was on time, respectful of our home, and worked efficiently to get everything installed and running perfectly. Before deciding, we cross-compared quotes and services from 15 different companies--and L & L stood out above the rest. They not only beat the competition on value but also explained things better than anyone else. Their transparency, clear breakdowns, and willingness to make sure we understood exactly what we were getting gave us full confidence in our decision. On top of that, their warranties are strong and gave us peace of mind knowing our investment is well-protected. Not only was the quality of the work excellent, but the people themselves were just great to work with--genuine, friendly, and clearly proud of what they do. It's rare to find a company that delivers both top-notch service and such a positive customer experience. If you're looking for reliable HVAC work, I can't recommend L & L enough. Jordan and the team really went above and beyond!

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.

Following a quick search on social media, many of our neighbors recommended Emporia. They had a technician out to our house in less than two hours, who quickly diagnosed the problem. Nicholas was simply fantastic! He indicated that he could get the part we needed but couldn't likely come back until the following Monday. I told Nicholas that we were having our 5 month old grandson for the weekend and I was concerned how cold it would be for him. Nicholas thought about it for a moment and said something similare to, "I try to figure out a way to get this done." To do this, I think he had to get it cleared with his boss since it would likely require him to work late. Sure enough, later that afternoon, Nicholas returned and fixed the furnace. We are so impressed with Nicholas and Emporia. I feel very comfortable recommending Emporia to anyone, and if you can get Nicholas - even better. The service was great, the price was fair, and I'm sure they know they could have overcharged me and I was in a position that I would have to pay it. They did not. Thanks guys! You are very much appreciated!
