  Dee S.★★★★★

• Maquavian was nice, professional and explained to me what was wrong with our a/c unit. He was very helpful and now the house is back cool again!

  Dawn C.★★★★★

• I had a heating and cooling company come prior to assure and they told me that the unit need to be replaced quoted me an expensive repair assure it came out and look and say Mr. Young, the only thing is going on is the fan on your unit is going out. We can replace that in your unit to be up and fine, so what went from being thousands of dollars went down to be a few hundred dollars. You like dealing with people that’s gonna be upfront and trustworthy.

• Professional Informative Friendly I highly recommend!!!

  cassandra J.★★★★★

• We had a great experience with this company and would absolutely recommend them. They were incredibly responsive, even coming out on a Saturday, and spent several hours thoroughly investigating the issue rather than rushing through the service call. Maquavian was able to identify the cause, explain everything clearly, and get our air conditioning back up and running quickly. Everyone we worked with was professional, friendly, knowledgeable, and very patient with all of our questions. We know our unit is older and will eventually need to be replaced, but we really appreciated the way they presented all of our options. There was very little pressure—just honest information and helpful guidance so we could make the decision that was right for us. Their pricing was also very reasonable, especially considering the time they spent diagnosing the problem and the weekend service. We really appreciated their professionalism, transparency, and willingness to answer our many questions. It’s refreshing to work with a company that makes you feel informed rather than pressured. We will definitely use them again!

• Friendly,good service and efficient

  Leslie S.★★★★★

• Called in the morning after my AC went out the night prior. Were able to get out to me same day and get my system back up and running! Were very professional from start to finish. Walked me through what the issue was (capacitor failed) and explained what the part that failed did and why it fails. Didn’t try to upsell me on anything, but did advise me my refrigerant was low. Advised against doing some work due to potential cost/risk. Definitely earned my repeat business. Thank you again!

  Craig B.★★★★★

• Can’t recommend these guys enough. I got 3 quotes for an AC issue I was having and trusted this company the most. Easy to get hold of an actual person & they came out same day. Felt like good people instead of car salesmen like some of the other companies. They replaced 1 of my units and fixed up the wiring and patched some holes in my duct worked. Really seemed like a thorough job instead of just trying to get to the next one.

  Cullen K.★★★★★

• I’m grateful for the integrity and professionalism displayed by Octavin during the HVAC service call.

  Tahnett M.★★★★★

• All around great guys and done a fantastic job with repairs to my heat pump. Very transparent every step of the way through the repair. Also affordable pricing and no gotcha price at the end of the service! Give this man a try you won't be disappointed!

  Reggie P.★★★★★

• Knowledge, quick even on weekends, and great customer service

  A. M.★★★★★

• Hello everyone! I want to thank Assured Quality LLC for their remarkable service and the young man under his leadership. Everyone was so respectful. Listened to my concerns and responded honestly without hustling me to buy unnecessary products and a new unit like the former company I had to come look at my unit. The other well known company was trying coerce me into buying a 11,000 unit. Thankful for Assured Quality for being in business as an honest Black African American entrepreneur within the community. One thing I love the most is the honesty throughout the process from beginning to end and talking with my son on the procedures needed to fulfill my needs. I will spread the word to others about Assured Quality LLC. Remarkable 👏 👏 👏 service. 100% Margueritta B. Johnson-Brown

  Robert H.★★★★★

• Octavio and his team did great work recently replacing my AC system. They have always done top tier work for me and were very helpful throughout the process of replacing the system, answering questions and offering honest, quality solutions. Never overcharging or overselling like others in the market often do.

  Blake H.★★★★★

• From the time I first reached out, Octavin and his nephew were at my home is less than an hour. Very professional and knowledgeable. They took the time to inspect everything in my home and gave me the fairest price after I spoke with several companies. They use very nice products and equipment. It was a pleasure dealing with them. Highly highly recommended them!

  Peter G.★★★★★

• Octavian did an amazing job addressing the issue with my system. He was out of the country on vacation when my issue started. He sent his nephew to do the work and was on the phone with him making sure everything was good. He’s knowledgeable, very responsive and helpful. I would highly recommend he and his team to be your HVAC company of choice.

  SHOOTERJAY 1.★★★★★

• I have been using Assured Quality LLC for 20+ years and they never disappoint. On a recent inspection, they found a leak and resolved the issue swiftly for a fair price. They are honest, professional and timely. I recommend anyone needing heating and cooling service to contact them ASAP.

  Maceo W.★★★★★

• Assured Quality were amazing, they came out within hours and made sure that the system was cooling as a temporary measure whilst waiting for parts, its so great to come across people that are responsive and professional and take care of clients. I would recommend this company to anyone.

  Dimitri M.★★★★★

• Octavin and his nephew responded quickly when I reached out for an estimate to replace my HVAC system. Communication was clear and consistent throughout the entire process, and he took the time to thoroughly answer all of my questions. They scheduled the work promptly and completed the job efficiently without sacrificing quality. The workmanship was excellent, and the pricing was very reasonable. I would highly recommend this company to anyone in need of HVAC services.
