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.

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!

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!

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 DiRubbo

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🎉

Kathy Holmes

Jason responded to my plea when all of the HVAC companies from A thru R had turned me down for an emergency cleaning on a listing that is scheduled to close tomorrow. Thank you for helping me to save the deal.EDITED: Erik went above and beyond for my client. I wish there were 6 stars! Thank you, again.

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

2018-01-19T16:49:56+0000

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

2018-01-03T15:50:27+0000

Honest!!! Company after 2 other companies misdiagnosed these peeps got it right on and fixed in less than 30 minutes!!! Highly recommend!!

Michelle Gruber

Jason came out so quickly to get us up and running!

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

Jason was AMAZING !!!! He came to us in a time crunch and really helped us out !! I'm so pleased !!! Will forever be customers !!! Thank you so much Jason!!!

Kelli Colleen Cooper

2017-06-08T02:04:28+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 is a great and reputable person that we highly recommend! Very trustworthy and honest!

Wanda Harmon Bohannon

2017-05-12T15:51:30+0000

Needed Jason for an emergency and he drove right over. He has the personality of someone you think you've known forever. He fixed the problem quickly and explained in detail. Highly recommend.

Jason was fast, friendly, and his prices were great!

Sara Myles

2017-04-15T21:27:13+0000

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.

Robert Hoffschneider

2017-04-07T03:35:05+0000

Called around 8:20 this morning and they showed up already. Excellent response time. Thank you so much

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.

Jaimee Reed Seibel

2017-02-12T02:40:53+0000

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!

Tim Flannery

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!

Heather Carmona Miracle

2017-01-10T20:19:44+0000

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

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!

Tim Cobbett

23:40 16 Jun 17

Amazing customer service! I recently woke up to 80 degrees in my home, coincidentally on the hottest day of the year so far. By mid afternoon these guys had us back to low 70's. I can not thank you enough.

Stella Sugianto

03:43 21 Jun 17

The technician made time in his busy schedule hearing that i have 2 little ones at home with ac that broke down on us in a high 90s day. I just cant thank him enough for what hes done for us today. Now my house is back to nice and cool. Thank you and i will for sure be calling u if i have anymore ac heating problem and recommend u to friends. Im a very happy customer!

Jeff Newcomb

21:59 06 Nov 16

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!!!

Robert Foltz

14:45 14 Feb 19

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!

Christina Dickinson

15:48 31 May 18

Amazing service! Jason and his team (we worked with Chris) are a prime example of a stellar small business - trustworthy, professional, and always willing to go the extra mile for a customer. Fast response times and are willing to work with your schedule. If you are looking for excellent customer service from a reliable HVAC company, call ROX!

Adam Koontz

15:22 14 Jun 18

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.

Teri Dillman

02:58 13 Jul 18

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.

Jill Fuemmeler

19:06 11 Aug 18

SUPERIOR customer service. Rox Heating & Air came through once again and in a time crunch! I am never disappointed by Rox. Not only do they have amazing customer service, they have loads of knowledge and are able to quickly pinpoint the issue, offer competitive pricing and are always timely, reliable and honest! I recommend them 110%. You won’t be disappointed.

20:23 06 Sep 18

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.

Richard Brown

23:08 07 Sep 18

Rox heating and air was great! They came out within a week of giving me an estimate and did an amazing job installing my new furnace and A/C unit! Their prices are very reasonable and the customer service is great! Chris did an amazing job installing and Jason was extremely quick in responding to all of my questions. I recommend this company to anyone looking for any HVAC needs!!

Matthew Prager

14:18 18 Sep 18

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.

Maggie Sanders

23:40 12 Nov 18

I am so very impressed with Jason and his team from Rox. My furnace has given me a few issues recently and they have delivered same day service to fix the problem. They are timely, polite and clean. I recommend Rox for any Heating or Air issues in your household!

Leah McFail

02:46 09 Nov 18

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!

Rita Gonzalez

20:17 16 Nov 18

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!

Judy Witt

15:40 21 Nov 18

Excellent service and prices! Chris did a great job and was very friendly!

Ann Burke

20:09 25 Nov 18

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!

Thorcon Shotcrete

23:46 28 Nov 18

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.

Brad Whitlock

16:04 18 Jan 19

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.

Jeremy W

13:10 25 Jan 19

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.

Mahesh Sundaresan

19:21 06 Feb 19

Excellent Service! If the reviews don't tell enough, our personal experience with these guys were great. 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!!

Nina Miller

23:25 09 Feb 19

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.

Jason and his team at ROX heating and cooling are the best in town. Always reliable, prompt and their customer service is excellent. I will not use any other company. I recommend this company to everyone.

Alex Chiapetta

13:43 30 Mar 19

I have had Jason and the ROX team repair and replace HVAC systems on 5 houses to date. They are responsive, reasonably priced, and stand behind their work. I am looking forward to having his teams on more of my projects.

Jacinda Anderfuren

13:00 31 Mar 19

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!!!

Pat McIntosh

12:46 06 Apr 19

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!

Nils Bifano

18:24 13 May 19

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. :)

Patrick Harris

18:51 15 May 19

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!

Kevin Sullivan

18:21 22 May 19

I've been using Rox for years. They continue to respond quickly, provide great service and fair pricing. Jason and everyone there is top notch.

Outstanding service as usual. Have Rox Heating almost since the company started. Service has always been great with qualified employees who quickly determine a problem and a quick fix.

Brandon Drescher

13:11 12 Jun 19

Was having AC issues and Jason came right out and was able to fix it and help us out. I’ve used Jason for years to service all my equipment and will continue to use his company. They’re honest and reliable, things that these days are hard to find with a company. I would highly recommend them to anyone! Thanks Jason.

Heather Carmona

16:35 29 Jun 19

Would give Jason and his team 10 stars if I could! Prompt, reliable, knowledgeable with amazing customer service. So grateful to have found this company....highly recommend for any maintenance and emergency needs!

The repair man Garrison arrived 10 minutes early and discovered the source of our problem within those 10 minutes. We had a bad ignition source in our gas furnace. He was very upfront about the cost to replace. He also gave us no-hassle recommendations regarding heating and a/c services that they offer. Overall, the visit lasted 30 minutes. We were able to pay on the spot by card using his phone. We will be utilizing your services again in the future and we will be recommending you to friends.
