HVAC reviews in Littleton, Colorado

Perfectly executed HVAC repair service that exceeded my expectations. The technician arrived exactly on time and demonstrated excellent professionalism. He carefully inspected the entire system and identified the problem quickly. The repair was handled efficiently and with great attention to detail. After completing the work, he tested everything thoroughly to ensure proper performance. The cooling efficiency has improved significantly. I truly appreciate their reliable and professional service.

From start to finish, the thermostat installation was seamless and efficient. The technician arrived about 15 minutes early, which was a pleasant surprise. He explained the process clearly, ensuring I understood every step. The new thermostat works perfectly, and the house feels more comfortable than ever. I appreciate the professionalism and attention to detail. Highly recommend!

The air duct cleaning was handled perfectly. The technicians arrived within the scheduled window and called ahead to let me know they were on their way. They were courteous, professional, and clearly experienced. I watched them work, and they were very systematic, ensuring every vent was cleaned thoroughly. They even pointed out a disconnected duct in the basement that they reattached for me, which explains why one room was always cold. That extra bit of help saved me a lot of money on heating bills. It’s rare to find such honest and hardworking service providers these days. Top notch!

I noticed a big difference in air quality after the duct cleaning. The dust buildup in my home has reduced a lot, and the airflow feels much smoother now. The technician explained everything clearly and worked very carefully.

This business did a fantastic job fixing the mold problem in our vents. They cleansed the system, eliminated all mold traces, and provided us with preventative advice. The air is fresh and pure now, with no musty odor.

Exceptional Service from Start to Finish!

Raphael, Bert, and Ty from Rox Heating and Air went above and beyond during our recent AC replacement. From the moment they arrived, they were prompt, professional, and incredibly knowledgeable. Raphael did a fantastic job evaluating our outdated system and explaining every step of the replacement process in a way that was easy to understand — especially helpful as new homeowners.

Bert and Ty handled the installation with care and precision, making sure everything was done cleanly and efficiently. They treated our home with respect, cleaned up thoroughly after the job, and even walked us through how to operate and maintain our new Lennox unit. The difference in airflow and cooling has been night and day!

What really stood out was their honesty, work ethic, and commitment to doing the job right. You can tell they take pride in their work — and it shows. Highly recommend this team to anyone needing HVAC service. Thanks again to the entire crew at Rox Heating and Air — you’ve earned a customer for life!

These guys were great. Unfortunately, we had to replace our furnace just a week and a half before Christmas, but they came out quickly before our guests arrived and took very good care of us. We decided to sign up for their care program and they worked with us on our second furnace as well. We went back to Rox because they replaced our air-conditioning unit last year. Would definitely recommend them!!!

Two days before Thanksgiving…came home from work and it was a COLD 55 degrees in the house. Most sincere thanks and deeply grateful to Kelly at ROX Heating and Air. She squeezed in a last minute appointment before the holiday. John was on his way home after a long day, but accepted the work appointment out of genuine human compassion. He arrived and was patient, friendly, and kind. An accomplished and trusted professional who used his specialty knowledge, training, and experience to repair and restore the furnace heat! Kelly and John at ROX were Thanksgiving blessings in disguise. Well-deserved 5 star rating. Thank You!

Great service at a reasonable price! What more can you ask for?

We woke up to cold showers and found the water heater exploded in the basement... By noon Chris was here, prepped the job while the new unit was delivered. They were back with the new water heater and done by 4pm. Perfect job!

Thanks to Chris, Jason and the entire Rox Heating and Air crew!

Our furnace was acting temperamental for a couple of days when it was very cold out. ROX immediately let us know when they had a cancellation to get someone out to our house early because it was not getting warm. Raphael (the tech) was friendly, knowledgeable and answered all my questions. He gave a couple recommendations on maintenance when he was here as well but didn’t try to pressure us into anything unnecessary. Very thankful for both the office and field staffs professionalism and friendliness!

Our air conditioning went out during the latest heat wave. We made a call to Rox Heating & Air and Raphael was at our house within 24 hours during a very busy week. After determining we needed a new system (ours was 20+ years old) he explained several options in different price ranges and gave us time to ask many questions. He answered every question thoroughly and helped us make the right decision for our needs. Best customer service we have received in a long time! The next day the crew was out to install and they were great to work with, efficient, and very clean and respectful of our home. Our new system is outstanding. We highly recommend this local business!

Jason & his team were amazing. They came out to fix our furnace within a day of our call (in December!) and the cost of their service was better than expected. I highly recommend ROX Heating & Air for any AC/Heat needs.

My technician Raphael was very knowledgeable and quickly addressed the issue I was having with my furnace. He also gave me helpful pointers to ensure my furnace lasts as long as possible. I am very pleased with the service I received and will definitely use Rox Heating and Air again.

I'd give 6 stars if i could. Danielle and John just finished the install of my new furnace and heat pump. Nova helped with decision making and paper work. Working with these folks was an absolute pleasure. Easy. Quick. Amazing price. Thank you!

Garrison came by to perform spring/summer preventive maintenance on my AC. He was polite, professional and courteous and he even fixed my filter sleeve without being asked to. I appreciate Rox, they’ve been great to deal with and I would definitely recommend using their services!

Had some service work performed today and couldn’t be happier. Communication as to arrival time for work was very comprehensive and helpful.
The service tech, Bert, was a pleasure to deal with. He was very polite and competent.
The workmanship was excellent. I’m a very happy customer.

Use them once and they will spam your phone and email looking for work, forever. It's been literal years since we even lived in the state and we still get spammed to this day and from new phone numbers every time.

We needed a new hot water heater. Rox Heating & Air was responsive, very competitively priced, and able to install our new heater quickly. I couldn't have been more impressed with the quality of their work and the skill level of their installers.

Dexter came today for our Spring Tune Up - he was professional, courteous, efficient, and took the time to explain the findings of his service/inspection and recommendations (there were no recommendations as our system is running perfectly!). We purchased our system from Rox 4 years ago, have never had an issue and would HIGHLY RECOMMEND Rox Heating & Air to anyone who needs a new system!

All around great experience. The sales person, Nova, was informative, didn’t pressure me, and worked with me on pricing. The installers were efficient and respectful of my home. They did really clean, thorough work. I will be recommending Rox to all of my friends.

Rox rocks. Heater wasn't working. ROX came out within a couple hours. Parts for repair were under warranty. They back their work.

Rox has maintained my HVAC for years. The techs are always thorough and professional. Peace of mind to use them. Highly recommend
