Rox, and the owner Jason, were great to work with. They went above and beyond to truly provide exceptional customer service. I will call them for all my future services and will recommend them to everyone in need of services.

Amazing Service, knowledge, pricing and really friendly staff (Josie, Chris and Jason). We are overjoyed as another company said they couldn't get a part and quoted a new unit, 14K. ROX fixed it for half the price (as PPros) and we are considering the maintenance plan to keep it running smooth. 5 star reviews speak for themselves.

Our daughter had to replace her air conditioning system last week. Rox had been maintaining her system for over a year. Rox stands by there service and made every effort to save the old system without overcharging or up selling. Her new system was installed within 48 hours. My system was 22 years old and was getting to the end of its service life. Garrison stopped by the day after I called and we discussed my needs and concerns. Having been given a fair price I agreed to replace my system. That afternoon the parts were put in mr garage my and at 9:00AM the crew came in and in 3 1/2 hours I was up and running. A couple of minor issues we discovered and resolved to my satisfaction. The crew has a great deal of experience and I feel comfortable signing a maintenance contract with them to keep my investment running well in the future. I would highly recommend this company.

We recently had ROX Heating and Air replace two old water heaters with a tankless water heating system. They spent plenty of time listening to our questions and understanding our needs. Jason and his guys did a great job with the installation and making adjustments to get it just so perfect. We are very satisfied with the entire process and highly recommend them knowing that they do such great work !

My furnace went out on a Friday night. My neighbor recommended them to me. I texted Jason and they responded right away. They came out Saturday morning. My motherboard was fried so they recommended a new furnace. Jason got me the quote right away and by Monday morning, I had a new furnace installed. Very fast and reliable customer service. Price was also reasonable. So far, the new furnace is working fine.

Shane and John were so wonderful. They replaced our 22 year old furnace today. They were super efficient, friendly, and came out the day after finding an issue with our system. Their speed was awesome since we have an infant and didn't want to stay elsewhere while waiting for furnace service. Thanks for everything!!!

Leah Marin Charleson

The sales and installation was flawless. A five star rating goes out to the entire staff. The ease of scheduling and phone courtesy was excellent. Shane and John were very knowledgeable, professional and friendly. Thanks Jason for a first rate experience.

Jason made sure we were scheduled for service on Wednesday. Garrison showed up and figured out what was happening with our old furnace. We desperately needed an equipment upgrade. John showed up on Thursday and installed our new two speed FrigidAire HVAC furnace, bypass humidifier, and smart WiFi thermostat. John has skills!!! I can tell the humidity level in our home is changing already. We are very happy new customers of ROX Heating and Air and love our new furnace!

I shard this on our community forum and I’ll post it here as well: Just wanted to give a huge shout out to Rox Heating. Our furnace couldn’t be used and needed to be replaced. I called them on Tuesday, they checked out our furnace on Wednesday and by this afternoon (Thursday) the new furnace was installed. I couldn’t be more pleased with the men who we worked with, Garrison and John. Thanks Jason Stenseth for such a quality company.

Betty Wellbrock Woodruff

2019-10-25T15:26:06+0000

Jason Stenseth is awesome. ROX Heating & Air is my go-to company for my business, my rental unit, and my own home. He’s knowledgeable, professional and stands by his work. Don’t go anywhere else.

Pam Kramer

2019-09-11T03:52:22+0000

We called ROX to get a second quote for replacing our a/c and Jason immediately noticed our current HVAC was oversized for existing ductwork. The other company did not! He explained the problems associated with that and was able to schedule our HVAC replacement the very next day. Our installation tech Shane was knowledgeable and walked me throughout new system. We recommend ROX!

Alyssa Grant

2019-08-29T19:21:41+0000

John, Jason and team provided an overall outstanding service. John, our technician, was professional, arrived during our expected time slot, never made us feel rushed and no sales pressure. Yet he was educated, informative and took the time to discuss other items we would like to consider doing to the property. I highly recommend!

Kathleen Yarberry

2019-08-28T01:14:14+0000

Price and customer service. Had a scheduleing issue and Jason called me himself to take care of it. Service tech found a bug in my AC condensor/fan contacts and that was it. Very honest In their diagnosis and did not try and make a big issue out of a very little issue. Great job will and will continue to recommend. Thanks Garrison!

Amber Lichfield

2019-07-12T00:21:06+0000

I do not know what I would have done without Jason, Garrison & Chris. Poor guys have in some combination been at my house every day for a week working on the crazy boiler system I have. Honest, dedicated & fair! Thank you! Thank you!

Kathleen Whinnery Murphy

2019-03-04T17:50:39+0000

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.

Eric Whalen

2019-03-03T21:31:27+0000

We had an emergency today and had to call Roxborough Heating and Air and Jason was so responsive and helpful. We’ve owned a house for 30 years in different cities and states and have dealt with many companies for varies things but never have we had the customer service we get from Jason. And he does an awesome job! The guy knows his stuff!

Tina Creel Drum

Thanks, Rox Heating & Air! Furnace went out and the next day they got a replacement installed! Great people and super fast!

Great service! The Rox Heating and Air team was professional, clean, and efficient! Thank you all for your hard work!! Ready to enjoy our winter with a new furnace!

Jenna Nicole

2018-10-05T19:02:17+0000

We highly recommend Jason! He is an extremely honest guy! We had a simple issue of a short/fuse problem..I imagine another company could have charged us alot more to diagnose this and perhaps sell us something we didn't even need. Jason found the problem and simply charged us a service call. Would definitely use again and highly recommend. It's hard to find honest repair help🎉

Our experience with Rox Heating and Air wasn’t as smooth as some, but Jason’s response when I gave him the feedback earned them an exemplary rating. Everything isn’t going to go smoothly 100% of the time, but I can assure you that with these guys they will stand by their guarantee and make sure they have satisfied customers. Thank you Jason for being a stand up guy!

Deb Dennis

Jason is great to work with and is very low pressure when it comes to making a decision. It was a no brained making the decision to go with his company to replace my homes HVAC system.

Jay Smith

Jackie Kramer

2017-07-22T01:19:26+0000

I can not thank you enough. Waking up to 80+ degrees in a house is never pleasant. Having it back down to 70 by mid afternoon was a lifesaver.

Jason came out and he was so helpful getting our unit fixed. He didn't just come out and do the job and leave, he showed us what he was doing and what we could do in the future to avoid complications. Very friendly, right on time, and super helpful

Lindsey Anderson

2017-06-09T15:32:42+0000

I truly appreciate Jason Stenseth. He is an exceptional worker and certainly learned many of his skills from working with his father, Dan. Today Jason got my A.C. up and cooling and is a very pleasant young man. I have known Jason since he was in elementary school. He helped his father install a new furnace in my other house in 2004. Luck would have it, I saw my community members recommending him and his business on our Facebook community page. I jumped on the chance to see him again. I recommend his work!

RaDene Kaufman Hannigan

Jason was great to work with. He replaced the furnace and installed an A/C unit in my grandparents house. They are older and are very hard people to please. He has went out of his way numerous times to go back and help them with any questions they have. You will not find that kind of customer service anywhere else. I would recommend him to anyone I know.

Super quick, low price and great guy! Thank you so much. We have a 16 month old baby and worried about the temperature dropping overnight. He came within an hour and had our furnace running in no time.

Jason at Rox Heating & Air offers an excellent rate with excellent service to back it up. Very professional and genuinely concerned about anything furnace/AC related that needs to be addressed. I highly recommend him!

2017-01-22T23:03:04+0000

Best company for AC and heating issues! Timely, professional, friendly and honest! Jason is the best! Thanks again, heat is ON and I'm no longer freezing!

My gas fireplace wouldn't stay lit so I called Jason at ROX. Within a few days, he was over at the house and fixed our problem. His customer service was extraordinary and his prices were phenomenal. I know who I'll be calling next time I have any issues with my furnace or fireplace.

Dan Couture

2016-12-16T18:23:09+0000

Jason came out late at night to repair my furnace. I appreciate your quick response and your great service! Jason from Rox Heating and Air - Highly recommended!! Thank you!!!

Dana Jilli Alli

2016-12-15T06:45:42+0000

I couldn't be happier with the work Jason did (furnace cleaning, A/C leak, new water heater). His communication, knowledge, and project completion were excellent.

Donna Cannizzo Hoffmann

2016-10-20T21:25:53+0000

Jason was recommended in the Roxborough Nextdoor several times for heating/AC work. Came back from vacation and my AC unit was running, but not cooling, and periodically the unit outside would make a weird noise sorta like the alarm sound that my dryer makes when it shuts off. Jason came out first thing the next morning, diagnosed the problem within 2 minutes, and had it repaired in less than 30 minutes for a very reasonable price. Highly recommend Rox Heating and Air!

Shirley Weinsteiger

2016-09-08T15:23:30+0000

Reached out to Jason after seeing tons of positive feedback on Facebook. After getting two outrageous quotes from the "big guys", Jason came out and saved my heart from exploding. A week and a half later I had a new furnace/AC system and what do you know my water heater had been leaking and he installed a replacement a few days later as well. Honest service at an affordable price. Highly recommend!

Kevin Lovelace

2016-08-24T02:35:30+0000

I found Rox heating and air from a roxbourough forum review. Jason from the start was honest informative and very helpful, he responded to my emails right away and played no games like other companies I contacted. I am eight months pregnant and had been without AC for a week, he and his team came out to my home today, they were friendly clean and hard working! I am happy to recommend Jason and his team anytime! Thanks for making my home nice and cool again

We could not be happier with the service we got from ROX. We called less than the night before for an appointment and they had our work scheduled the next day. Our Technician Garrison was professional, a clear expert in the field and easy to talk to. He explained everything that needed to be done and all of our options. He completed the work swiftly and we couldn't be happier. I have already recommended ROX to several friends for their AC needs.read more

Jason was awesome and his estimate was very reasonable. He also spent a lot if time on the phone helping my husband make the decision of what was the best AC/furnace/water heater option for our home. The 2 guys that came and did the work were on time, friendly, and thorough when it came to explaining our new unit and its maintenance. They explained warranties and I feel confident that they will stand behind their work. I highly recommend Jason and his team.read more

Jason and his small team provide an excellent, professional service without price gouging like some of the “name brand” HVAC companies here in Denver. Trust me, when you hear those other names on the radio, you’re going to pay at least 30% more for no added value. Jason always goes the extra mile to ensure the system he installed continues to provide me and my family the quality home environmental temperatures he promised (and it very much does, always!).read more

Our AC stopped working late on Friday night, when it had been over 100 degrees outside during the day. After calling over 5 different places and getting the earliest appointment for the following Wednesday, we were a bit hopeless. ROX returned our call the next morning and by 10:30, John arrived. He was super friendly and professional explaining everything to me and taking the extra step to also call my husband and fill him in on the concern as well. Our thermostat ended up going out so it was a quick fix, and John made sure the new one he put in was programmed to our liking. He was out within an hour. Highly recommend ROX and will be keeping their number for future heating and cooling concerns!read more
