I called Front Range to get a second quote. There was a family emergency when Rob came so he quickly listened to what needed to be done and provided us with estimates and lots of information in a short period of time. He the answered my multitude of questions via email and offered several different options. We went with Front Range based on their awesome warrant as well as their guarantee to repair any damage to the home (which the other company we contacted did not guarantee!)(no damage was done but was happy to have the peace of mind that had there been any-it would have been covered!). The installation of the complete HVAC system was completed in 1 1/2days. Everything went smoothly and was explained to us in detail. The system is working great and happy to know that Front Range will be there to service it twice a year. Also very happy with the 0% financing option. Thank you Front Range!

Our first experience with Front Range was a broken heater in the middle of winter. They came out right away and fixed it without charging ridiculous emergency rates. We recently used them to install an AC unit and a new furnace. They are always prompt, professional and do exactly what they say they are going to. There was no pressure sales tactics either when we asked for a quote on the system. We are very pleased with their work and their crew.

Very dedicated team! The installation folks worked well past closing time to get everything installed. Another technician came the following day to finalize the installation and certify the equipment to manufacturer specs. This is my first heating & a/c purchase, however it's apparent they strive to do a first class job.

We’ve had to replace our furnace, AC, and water heater all within the span of two years. I like the consistency and the top notch quality units that are used. These guys don’t traipse in with shoes on, always clean up as best as they can, and give me a quotes and stick to their numbers. No hidden fee nonsense.

Kimberly Emerson LeBlanc

Helpful, on time, professional, responded quickly to inquiry and kept their word with what they said they would do. We made a follow up appointment when we had concerns over a tiny drip. They made sure that all was well and ended well. Thanks for being there HVAC. They helped ease our stress over those life moments, when everything doesn't go according to plan.

Jeremy and his team provided exceptional care to my client, of whom is my sister. My sister, Rianna is about to bring home my nephew Jace from Children's Hospital as he suffered a spinal injury on 12/15 which left him paralyzed from his waist down. Rianna needed to have a new furnace installed and Jeremy and his team responded immediately, made an educated decision on what was necessary for the home and within a couple days Adam was there to install the new furnace. Jeremy is a huge supporter of Castle Rock schools and families. If you are needing your furnace, water heater or air conditioner serviced, please call Front Range HVAC.
As a Realtor, this market requires companies to respond quickly to homes currently being sold, if you are needing inspection items to be taken care of- Jeremy and his team are who to call.
Thank you Front Range HVAC for your contribution to Castle Rock!!!

We have used front range for our rental house in Castle Rock for the last 4 years. They have always been very courteous and explained
in detail their invoices. They have been very fair on pricing and have never tried to over sell us. The staff and service techs are very customer service oriented. We highly recommend them.

Angel and his assistant did a great job for us in all respects. They worked hard and long hours. Explained the new humidifier and thermostat. Both were very pleasant as well as knowledgeable and competent. Would not hesitate to recommend.

Rick Zellen

Jeremy and his team were professional and handled our furnace units as if they were in their own home. Glad I made the switch to Front Range!

We’ve used Front Range HVAC multiple times for a variety of different jobs. The best part about this company is their dedication to their customers and wanting them to feel informed and pleased with the work. They are timely, professional, do a thorough job, don’t leave a mess, have good prices, and are available for questions. The only HVAC company I’ll call.

My furnace quit in a very dramatic fashion mid-November 2019 and the process to get a quote for a replacement furnace was rough. My home was built in the 1940's and the 30+ year-old furnace had been installed in the crawlspace in a very "DIY" manner. The ductwork was an absolute disaster and only the devil and the original installer will ever know how the old behemoth of a furnace made it through the crawlspace entryway. Two companies told me they could do the job, scheduled the install, then backed out. TWO. At this point, my heat had been out for over a week and I was losing my mind (it was a cold November). I became a little neurotic and got four more opinions. Thankfully I did, because the sixth and final company I contacted was Front Range HVAC! Rob came out for a consultation and was very professional; he listened to my rantings about the other companies and eased my concerns about the install. Ken and his installation team (primarily Jesus and Tristen) were respectful, showed up on time each day, and did a great job of explaining the process to me. Ken ran into several roadblocks but was able to troubleshoot the issues at hand and get the job done. This job was a challenge — the install took an extra day, the crawlspace doesn't have much clearance, and the weather was crap (rain, snow, cold) — but Front Range was committed to getting this project done correctly.
