Justin #48 is a great service technician and honest person. He was logical in his approach, thorough in his evaluations, and reasonable in his assessment of how best to proceed considering the current age of the AC equipment. I will always ask for Justin #48 for my future HVAC service needs.
William Steigers
Very happy with the experience!
I had been having intermittent issues with my AC unit and it finally stopped working. I called and someone was dispatched and arrived within an hour of scheduling. Brandon Freed was extremely nice and kept me informed of the problems as he worked. He was able to get my 25 year old system working again. I will need to replace the unit soon but for the time being he was able to get it working! Very happy with the experience!
Clay Lupear
Very polite and respectful
Very polite and respectful, great communication. The AC was making a clicking noise, which Chris checked out to be nothing related to the motor. Paid 89.00 for the service check. It turned out the clicking noise was the door vibrating when the unit was running.
Yolietta Stevens
Cole did an amazing job
Cole did an amazing job. From the moment he got here, he explained everything he was going to do. The AC is now working as expected.

Same-day weekend solution
Chris came out on a hot, 96-degree Sunday afternoon and performed persistent troubleshooting on my condo’s “First Co” air handler to eventually diagnose a loose connection near the switch. Nothing seemed awry until he did the examination with the power on. It was great to get a same-day, weekend solution and be back in business with cool air!

Brian Made Me Feel Safe
When I saw Brian at my door, I knew that my air condition problem would be fixed. He is so respectful and always has a smile. As an elderly person, you need to feel safe whenever anyone comes into your home. Brian’s attitude and friendly demeanor made me feel comfortable and safe. The office staff is a reflection of their field staff; the company really cares about their customers. Thank you, Brian, and thank you to the office staff.
Claudia Jones
Exceptional Customer Service
Exceptional customer service from first phone call to schedule to completion of service appointment to diagnose A/C not cooling properly. Extremely impressed with your technician Sam C. I will gladly be telling everyone I know to call for any of your services! Thank you so very much!

Thorough, Honest Work from Zach
I started with this company when they were NOW in 2012, and 13 years later, I have no regrets. I've had different service reps work on my furnace and condenser during that time. This is a review for the latest rep. Zach has been doing the inspections on the furnace and condenser for the past year. He always explains what he finds, including the pictures and all of the data. He just finished work on the condenser and showed me all of the current data and the data from the last inspection and how they compared to each other. He is always very thorough in his work and always polite. If you want someone who will do thorough, honest work for you, Zach's your man.
Rex Conway
Did an amazing job
Julian Martinez with Quality First Plumbing/Allen Services did an amazing job checking out my furnace and A/C. He's very knowledgeable and able to talk you through everything he's doing with each step. He was very thorough and checked everything. He was also great with my crazy dogs and kids. I felt good about the whole experience. Thanks Julian and Quality First!
Avery Lombard-Knapp

Good service
Good service, showed up on time, did everything for the air conditioner service.
Clifford Lopez
He Is My Guy
This guy Zach J. was so amazing. He went over all my questions, and I had many. He showed and taught me things about my AC that I didn’t know as a new homeowner. There was no pressure at all. He suggested things and even called his boss to have me ask the questions again just to make sure that I felt comfortable with the answers and the pricing. He will always be my technician. He remembers the little things from the last visit. That was such a good feeling. He is my guy. I am a nosy homeowner, and I am always wanting to learn. He is great!
Rosemary Moe
A Good Experience Altogether
Zack did a great job of servicing my A/C. He was courteous, well informed, and kept me abreast of the process of cleaning and inspecting the units. He gave me a quote on a couple of concerns he discovered on the water heater and ducting. A good experience altogether. Regards, Rick
Rick DeBolt
My A/C Is Clean and I'm Ready for Summer

Sam was the utmost professional
We contacted Quality First Service Group to fix our A/C unit not working. Sam was our technician, and he was the utmost professional. Sam explained every aspect of our problem and offered the best solution possible! We are very pleased with the work provided and will use Quality First Service Group for our needs in the future. Thank you!

He fixed the system in no time
Our A/C went out yesterday afternoon, so I submitted a request online last night. They called me first thing in the morning to let me know they’d come take a look. I called several other companies and not ONE called me back. Jeff showed up, diagnosed the problem (capacitor needed to be replaced), and fixed the system in no time at all. He really took his time to educate us on some different maintenance that should happen and things to look out for in the future. So happy that we called Now Heating and Air, and extremely thankful to have had Jeff come out so quickly! Thank you so much!!
John Sabala

Good service! Service man was Tim. I will call back next month to schedule the compressor cleaning with Tim. Thanks.
Norman Aaronson
Incredibly Helpful and Knowledgeable
Zack was incredibly helpful and knowledgeable in diagnosing the issue with my cooling system. His expertise made a complex problem much easier to understand and address.
Darzelle Efferson
He did such a fantastic job!
I used Quality First because I had an issue nearly all summer with my AC. Cole was the technician who came out to help me, and he did such a fantastic job! He was very thorough in his examination of the issue, and he did an excellent job at repairing the problem. On top of that, he was extremely kind and easy to work with! I’ll definitely be using Quality First again!
Sonya Barnett
Very pleased with the service
I was very pleased with the service and interaction I had with Sam from Quality First. Everything was explained to me very clearly, and options were given on how to help get my air-conditioning running again. Sam was respectful and very easy to chat with, I appreciate that!

Very knowledgeable and helpful
Justin came in, was very knowledgeable, and was able to determine the problem. He gave me an estimate, broke down the estimate, and was on his way. Before he left, he got my AC up and running. Thank you, Justin.
John Lucero
Second to None
Second to none. Justin and Taylor showed up to troubleshoot my condenser issue. Here 10 minutes. They found the problem. I was quoted cost of repairs. Justin checked to see if warranty was in effect. Yep, it was! Lennox paid for replacement parts. Very professional, informative, and all-around nice folks.
Glenn Jones
Friendly, professional, and efficient
Dexter was friendly, professional, and very efficient. He assessed the problem very quickly and had my AC unit up and running again in no time.
Laura Slack
Polite, Friendly, and Professional
Josh G. came to our condo yesterday. He was polite, friendly, and professional, and he had our AC up and running in a couple of hours. We are so grateful and look forward to Quality First yearly visits to ensure our unit is running properly.
Sue Smith
Friendly, Kind, and Professional
The folks at Now have always taken great care of our furnace and AC. Most recently, Zack came out to do a regular check-up on our AC unit and found it was not working optimally. He whipped up 4 different quotes so I had a choice on how to proceed, rather than just hitting me with sticker shock. He got the work done while being friendly, kind, and professional. And, when he pointed out I had wasps living in my electrical box, he gave me a tip on when to attack them.
Megan Sinnock
Sam was very kind and concerned
Sam arrived to install several components to my AC. Several issues arose: the pump was the wrong pump, and the fan blade was stuck on the pump. He did get it off; however, it could not be reused again. Sam was very kind and concerned about no AC until Monday. He overnighted the needed parts; they won’t arrive until Monday a.m. Sam requested a portable AC unit; so far, it is working out well.
Mickey McDonald
I really like this company.
Justin Adams was on time and was very good at explaining what was happening with my air conditioner. He asked about my water heater. He said it should be flushed once a year, which I did not know, so I will have it done this fall. I really like this company.
