I Highly Recommend Quality First
I called Quality First at 3:30 on a chilly Saturday afternoon, and they arrived at 5. Our furnace had been down one day, and without their help it might have been a couple of days more. An hour after their serviceman arrived everything was working, and the charge was quite reasonable. I highly recommend Quality First.

This group is top notch
Holy smokes, this is the second time I’ve called Quality and I am equally impressed. Cole was here and was one of the most thorough techs I’ve ever experienced. He really walked me through the issue with my furnace, made the repair, tested his work, cleaned up the entire area, and offered me recommendations on keeping things in tip-top shape. I hope the merge with Allen doesn’t impact the service quality and pricing because this group is top notch with very fair prices.

Zach from Now Heating and Air was EXCELLENT!
Zach from Now Heating and Air was EXCELLENT! Timely, friendly, and honest. He diagnosed the problem with our furnace in a jiffy and gave us an accurate and transparent quote. We live in the mountains and he went all the way back to town to pick up the parts to take care of the job the same day. He even emailed us pictures of all the parts (old and new) and evidence of the work that he did for our records. It's snowing today, and we are very grateful to Zach and his team for our working heater. We will definitely be using him again in the future :)

It was 45 degrees in our home when we returned from the Thanksgiving holiday. Now Heating and Air was there the day I called them. Zack was very thorough and informative.

Thank you for great service!
This is our second positive experience with Quality First, and I would highly recommend. Our heater stopped working, and Carson came out to see what the issue was. He thoroughly explained the issue, including how this impacted our heating system. He suggested regular annual maintenance for preventative care so our heat doesn’t stop working again. We will definitely do this. Thank you for great service! 🙏

They Go Above and Beyond
I tried to schedule with other companies and never got a call back, or they wouldn't work on my heating system, and Quality First were so responsive, helpful, and communicative. They gave me the facts about my system, offered me options, gave me lots of information to consider, and then followed up right away for the next steps. I appreciate a company that goes above and beyond, is kind, and responsive. Those feel like basic business services but they're often hard to come by. Thank you for being so nice to work with.
Melissa Carrera
Excellent service, would recommend
We had no heat at our home this morning, so I tried to troubleshoot. After failed attempts to get the furnace to kick on, I called Allied. Within 30 minutes a tech was at our home working on the furnace. Elyas Torabi was the technician that was sent to our home; he was so friendly and helpful. He went above and beyond for us. He needed a new part, but in the meantime he got the furnace to work. He ran to the shop to get the needed part and was back the same afternoon to install the new part. Excellent service, would recommend Allied Heating and Elyas Torabi! I am in the homebuilding business and work with a lot of trades, and Allied exceeded my expectations.
Peg Ongna
Thank You, Hunter
Hunter was my technician this morning. He was helpful checking out the pneumatic heating system in my condo. Since I was not knowledgeable about the system, he had the patience to explain the valves, feeders, thermostat. Thank you, Hunter. It’s so appreciated!
joan manary
Pete went above and beyond
Pete not only fixed my heating issue, he went above and beyond in explaining to me what he was doing and educating me about the entire heating system. I would absolutely want Pete to work on any heating/plumbing issue I have in the future.
John Daniel
Thomas Furlong Is the Best!
Thomas Furlong is the best! I am without heat, and he spent a lot of time explaining what type of system I have (pneumatic). He also connected me to the company/person who will be here first thing tomorrow morning to get the problem fixed. Thomas was cheery and respectful; most helpful in assisting and assuring me that I won’t freeze tomorrow!
joan manary
Five out of five stars
I live in an apartment complex, and my hot water and furnace went out over the recent polar vortex storm. Our complex maintenance team was unable to perform the repair, and Quality First Service Group came out to do the repair. Carson and Phil were both exceedingly professional, kind, and responsive. The entire system was eventually repaired, and these two gentlemen worked nonstop to complete the job. They were courteous of our space, very easy to work with, and got the job done. We’ve been without heat and hot water for 5 days, and we are so thankful for their work. Thank you, Carson and Phil, for your exceptional skilled trade! Five out of five stars, would recommend.
Tyler Houston
He Saved the Day!
My heater stopped working on the coldest day of the year. I called several companies and no one was available. I called Now Heating and Air and was told they could send someone out soon. I got a call a few hours later and Miguel showed up 5 minutes after the call. He examined my furnace and told me what was wrong and fixed it on the spot. He saved the day! He was very nice and even wore shoe protection inside my house. I will use this company again in the future and recommend to all who ask! Thank you!
Shawna Campos
I could not be happier
Jackie helped me greatly to schedule an immediate diagnosis of a home heating system that was not heating on a very cold night.
Justin did a quick but thorough analysis, provided an excellent overview of issues found, and gave me options for correcting current issues and for future preventative services.
I could not be happier with the work Justin did and also with the ease of doing business with NOW.
I highly recommend.
D Sharpe
Professionalism and Care Surpassed Competitors
Kurtis came through right away when our ignitor stopped working and got us with heat before the house even got cold on a wintry day. Quality has helped us quite a bit. Prices are comparable to other quotes we've gotten, but the professionalism and care have surpassed all other competitors that we've seen. Thanks, Kurtis!
Yannek Smith

We use these guys for all our heating and air needs.

I just called them from Hawaii to repair something, and they came by in a few hours. Now my mom has heat while she watches the house! 10/10 would recommend.
