Great service fixed my furnace in one look. Had another hvac company come out and tell me that I needed a new gas valve $200 bucks I did that but it didn't fix problem. Rox Heating and air came out told me the igniter wasint in the right position put it in the right position works like a champ heck I probably didn't even need a new gas valve. Thanks again Rox Heating & Air I will be calling them again if needed.

I called Jason in the middle of a 98 degree day to set an appointment and he fit me into his schedule within an hour or so; he immediately had an idea of the problem only to figure out it was that and more. He thought he could have it done the next day...unfortunately the wrong part arrived but Jason was extremely apologetic and assured me it would be a priority the next day and it was. I wasn't expecting such a prompt initial appointment, let alone having it fixed within two days! Jason is also very respectful and down to earth and super personable. So glad I followed the recommendations given in Word of Mouth-Highlands Ranch when I was in a pinch. Love supporting local, small business!

Spoke with Jason on the phone, and got a quote for installing a humidifier. They came out and installed it perfectly, for a very reasonable cost. They did a great job for me and I referred them to my Mother in Law for a cleaning. They tried to charge her LESS than they quoted, and they took care of another issue while they were there. Will use them again for sure!!!

Rox Heating and Air did our AC/Furnace, and has been quick to respond if we need anything at all. When our contractor for our fireplace dropped the ball in scheduling our gas to be hooked up during the installation, and everyone else was booked 2 weeks out, and right before the birth of our baby son, Jason cleared out room on his busy schedule to accommodate us, absolutely coming in on the clutch for us to get the gas line set up just in time before baby was born. Couldn’t be more appreciative!

Jason, the owner, is one of the most honest contractors I've ever worked with. He is very upfront over the condition of your utility equipment and proposes the best and cheapest solution to get you back up and running. It's refreshing to hear "this is an old system but you can probably get a few more good years out of it" instead of being pressured into updating or replacing equipment early. I've never hesitated to recommend him to my friends and coworkers who are in need of HVAC work.

Rox saved my real estate deal the night before closing. Rox was the ONLY hvac company who could accommodate my last minute need for a furnace clean/service. I am so thankful they were the company who helped...perfect customer service by Erik. You are my new #1 HVAC recommendation. Thank you so much.

Jason is a great face to the company, and will personally ensure jobs are done to the satisfaction of the client. They are quick to respond, have an answering service to make sure that the techs always receive the calls, and they are knowledgeable, friendly and professional. They won't immediately suggest you need to replace an AC system when there is a service call needed. They will diagnose and locate the problem, and get it fixed asap. Highly recommend! Their radius is huge, so you will have no trouble getting service.

Jason and his team were very professional and knowledgeable. Prompt to answer all my questions, and never once tried to sell me more than I need. I called them for a new AC and furnace in the dead of summer, and they made it happen quickly and affordably.

Jason was personally recommended by a colleague and we couldn't be more thrilled with Rox's work. He never tried to up-sell us, instead talking us down to a less expensive unit than what we thought we needed. Personable, accessible, quick to get us on the schedule, and bar-none customer service. Our house was shoddily built in the 70's and his team not only had to completely move a water heater, but had to creatively figure out ways to run ducts through our nonsensical ceilings. They managed it without complaint, and when the water heater wasn't adjusted quite right after the install, his guys were back immediately the next day to perfect it. Will be recommending him to everyone we know, as well as using him for our new AC when the time comes. Thanks, Jason!

Everyone I worked with was very professional. They even got me a better A/C for a great price than any other place I got estimates from. My unit is in my attic which seemed to be a problem for other companies, but they made it work without any issue at all. I would definitely recommend and use them again!

I highly recommend ROX. Chris really impressed me with his knowledge and customer service. I have an old house with an old furnace and he got it working again this winter until the unavoidable new install in the Spring. He was on time, efficient, and patient with furnace/client. Highly competent honest, and a pleasure to work with. I am extremely grateful my friend recommended me to ROX. Thanks, Chris!

We called Rox to come out and Replace an old unit and to add a completely new unit. They were very quick to respond, reasonably priced, they were very professional in all communications from the quote throughout the entire install. They made sure everything was clean and to our expectations when they were done. We are very happy customers and will be calling Jason and his team for any work in the future.

Great experience working with Rox. Easy to schedule the installation and Jason and his team performed a solid installation of a AprilAir 800 series steam humidifier into our new construction home in Sterling Ranch. I would personally recommend and they will be my first call for any further work.

These guys have been great. Last summer we had an AC issue and they were out the next day to get us taken care of, so earlier this week when we had a furnace issue, I called them again. Jason was able to come out the next morning and get us working in no time. I recommend him to everyone.

From Appointment scheduling to service.The technician showed up on time, and called before arrival, walked thru the issues we were having with furnace, and best of all kept our expenses to a minimum. Very please with the service call and this company, will be my go to company moving forward! Thank You!!

I was thrilled with the experience I had with ROX heating & air today. I awoke to a cool house that was growing cooler quickly. I called 4-5 heating companies but could not get an “emergent” appt until Sun. PM or Mon. AM. I found the add for ROX heating & air & spoke with Jason. He explained he was booked but if he could finish his appts. he would come by. Thankfully he was able to fit me into his schedule around 2pm.. about 2 hrs after my initial conversation with him. He managed to squeeze a service call into his schedule. He arrived promptly & worked quickly & efficiently. I was extremely pleased with his prompt attention & what I considered very reasonable charges. I would recommend ROX heating & air without hesitation & plan to use the company for any future needs.

I received a super quick weekend response through their Facebook page messenger. I was very pleasantly surprised by the excellent communication and customer service. They were willing to help when others wouldn’t and at a reasonable price. ROX has earned my future business and they’ll be the first I recommend to others.

Jason his company and technicians are amazing. We recently sold our house and need to have our furnace clean and certified per our contract. At first I used a company I found near me and they came out and told me I needed to put 1300.00 worth of work in my 7 year old furnace in order to have it certified...... now I am not an idiot and quickly said I’ll get another opinion, that’s when I called ROX. I had three days to get this done and they sent out a guy ASAP to check it over I needed one thing done which the tech did right in the spot and certified it and it was 178.00! This company is honest and they DO NOT make up things or take your money! They will forever be our HVAC COMPANY!!! THANK YOU SO MUCH JASON AND THE ROX STAFF!!!

Without a doubt, the best HVAC service I have EVER had. Chris was wonderful to deal with. Diagnosed the problem quickly (the 32 year old furnace in my sister-in-laws home was shot!) Chris was back the next day with Shawn (Sean) and had the new one in and running in under 3 hours. They were thorough, efficient, and very professional. I am very happy with the quality of work, the quality of the new furnace, and the cost of the replacement. I will now use ROX Heating and Air for any HVAC issues in my own home, I cannot recommend them highly enough!

Last fall, we had a company out-right disable our furnace without fixing it, leaving us without heat during the first big snow storm of the year, and were very unprofessional about it. We knew the furnace was getting a little old, but having recently moved into the house, we didn't know it's full history. When I reached out to Jason and his team, they sympathized with our situation and got us a great deal on a brand new furnace in record time. Thank you so much for making a good impression on these new Roxborough residents, Jason, and sorry it took me so long to get this review written. :)

The guys at Rox have been nothing short of AWESOME! From fully explaining all of my options for a new AC and Furnace to patiently allowing my wife and I to change our minds 50 times! Jason and his team are great communicators and Made this entire process seamless. And I can’t forget to mention the value! Another company has provided a quote for the same job and when I told them what Rox was offering, the salesman literally told me”Go with them because we can’t cone close to that”!! Life long customer!
