"FURNACE INSTALL - Phil from L&L Heating & Air Conditioning was very professional and knowledgeable. He listened to me when I stated that I wanted a high efficiency furnace --- he did not try to sell me something that I did not need or want. The crew showed up on time, completed the work well within the scheduled time frame, and cleaned up thoroughly. I have recommended L&L to my neighbors and friends."

"Listen-up Folks! One of the most important decisions for a home owner is the repair or replacement of a Heating and Air Conditioning System (HVAC) and related components--an Electronic Air Cleaner, Humidifier, Thermostat and Water Heater. Consequently, access the reviews of customers who have received exemplary service in the purchase and installation of a HVAC System. A total of five proposals and estimates were obtained from HVAC companies for replacing my HVAC System. Front Range Mechanical Services submitted the lowest estimate; whereas, the remaining four included Costco (Cooper Heating and Cooling); PumbLine; Southwest Heating and Air Conditioning; and Applewood Plumbing and Heating. Notwithstanding, the lowest bid is only one aspect of the equation and I selected FRMS due to several factors: (1) the amazing knowledge base and thorough presentation by Stephen Korff, Home Comfort Specialist and owner of the company; and (2) the quality and warranty of the Amana and Trane products to be installed; and (3) the comprehensive certification of all HVAC Technicians employed by FRMS; and (4) the A+ rating with the Better Business Bureau. Look no further folks! You are in 'good hands' with Stephen Korff and FRMS. Conclusively, from 'start-to-finish' every aspect of this transaction was a pleasant experience; including the outstanding service provided, subsequent to the installation, by Stephen Korff and his Technicians in answering all questions pertaining to the operating System. I am confident this testimonial will alleviate any uncertainty regarding who should install your HVAC System. Daniel A Highlands Ranch, CO"

"Jason showed up in a timely manner. He worked very hard to replace my AC in the summer heat. It was a complicated job and he did great. Also, he was very honest and was able to help us keep the overall cost down. Shortly after the AC the mother board on the furnace went out. He was able to come out and perform a warranty repair on the furnace very quickly. Overall, I would highly recommend this company to anyone looking for HVAC services."

"We called FerguSons to service our AC system. They showed up on time, exactly when they said they would. Professional and knowledgeable, did not try to sell us a new system. Explained to us exactly what was going on with our AC system. Cody repaired our AC in no time. We will definitely recommend FerguSons to our friends and family."

"Ryan was great! We had him install two large light fixtures on a high, sloped ceiling. His estimate was the lowest of several we got, but it was Ryanâ s communication and professionalism that really made it an easy choice. The job itself took about four hours, and he was incredible throughout. Ryan did excellent work, but he was also very friendly and easy to talk to. And we couldnâ t be happier with the finished product. We will definitely call Ryan again when we are in need of handyman services."

"During a serious cold snap my 50 year old boiler died. They came as soon as I contacted them and the next day they promptly replaced it with a brand new one. My new boiler is already up and running and the temperature in my 112 year old house is heating up quickly. Great service, polite young HVAC professionals."

"We took many bids. Marty offered the best quote on a full Carrier furnace and ac. He even offered 5 year financing through Wells Fargo. They did the job quickly in two days. We had a concern about the way the system was running. They came back the next day and fixed the problem without extra cost. The best part was that we paid exactly what we were quoted. No surprises. He was easy to work with and did good work."

"My wife and I found PipeWorx online, called them, and could immediately tell that they were experts. Courteous, professional, and hard working, they arrived on time, worked all day into the evening on a Saturday and returned on Sunday to finish the job. With only 2-days notice, they replaced our entire system (boiler, pump, valves, manifold, etc) and left us with portable heaters to keep our house warm overnight. They pride themselves on not only the function, but equally on the organization and appearance of the finished product. Compared to the four other quotes we received, PipeWorx was the only company who didn't over-size our boiler and offered the lowest total cost. Thank you Josh! We'll be recommending you to our friends."

"I've used Applewood Plumbing, Heating and Electric in the past and have never been disappointed. Preston came to perform a routine maintenance check on my furnace and noticed a problem with my water heater (potential carbon monoxide leak). He explained the issue and contacted one of their plumbers, sent pictures and, with my approval, arranged for immediate service. He then completed the inspection of my furnace and explained the inspection & the results and answered all of my questions. He was knowledgeable, courteous, and was able to explain things in a way a non-HVAC guy could understand."

"We have been using this excellent company for over 20 years and would highly recommend them. Our recent installation of a new Rheem furnace and AC reinforced our confidence in this excellent company. Though there were a few hiccups in the installation, I received the most courteous and concerned assistance one could hope for when purchasing and installing expensive and important equipment. Thank you for our new system! With a shout out to all those who went above and beyond: Troy, Jensen, Trystan, Keenan, Daran, Craig, A'lan, Brandon, Sol, Agnes, and everyone else that showed up. You were a great comfort and helped make this installment a success!"
