They didn't listen to what services I requested, I waited 3 weeks for them to come out and they send the wrong type of technician I needed for my ac unit and heat pump. I also asked for a oil furnace clean and maintenance and the technician said he doesn't do that. I had just wasted my time so i sent them home. They did check my Freon and said it was as completely empty which was false.

I hired another company and they said it was low but not empty, 6 pounds out of about 11 pounds was put back into the system. They messed up and still charged me $95 diagnostic fee. I called to try compromise and they didn't want to. Even before I called them I sent them several emails with no response. I made it clear I didn't want to be charged for bad service. They chose money over their reputation.

We had our HVAC unit replaced back in 2017 by A Quality. We have the yearly contract and a technician comes out every 6 months to do maintenance. We have never been disappointed by the service. The technicians go above and beyond! We love A Quality and would definitely recommend! Services: HVAC system maintenance, Install AC, Repair HVAC

Highly recommend A Quality. We needed a new heating system and knew the job was not going to be easy or inexpensive. So glad we chose A Quality. They were aware we did not have heat. They were able to work magic and move our installation up. Their cost was what we expected. Their technicians could not have been more professional and courteous. Thank you, A Quality!

Cody and Brad did a complete system change out in 1 day. They are polite, attentive to details and awesome to work with. They are an asset to the company and outstanding representatives. A Quality was recommended to us by a local Westminster builder and I would recommend them to anyone needing service or installation

I called them on Monday on a recommendation from Ensor Plumbing who I trust a lot. They tried to schedule me for Tuesday but it did not work so they said they would be out on Wednesday between 8 and 12. They called at 10:30 and said they were on the way and will be at our house by 11:20, which is exactly when they arrived. The technician Justin got right to work, found the issue, had the part on his truck and fixed the issue then checked to make sure everything was working properly. He then explained what he did and why the part failed. The cost was less than I would have expected. Will definitely use them again!

Our experience with AQuality has been outstanding. First of all, they were able to send a tech within 18 hours of my call, nearly a miracle in the heat of summer. This relieved my anxiety quite a bit, as we had only been able to schedule another company for almost two weeks out. Since part of our problem was leaking water off the A/C coil, this would have been an extreme inconvenience, as well as lead to a flooded basement.

The tech, Anthony, was in my driveway at 8 a.m., and proceeded to analyze my problem quickly and efficiently, and answered my multitude of questions competently and completely. We apparently had a low coolant situation, and by replacing about two gallons of coolant was able to solve the problem at least temporarily. It gave us time to examine our options for possibly replacing our system, which is now 23 years old. We could not have hoped for more. Thank you sincerely, AQuality.

Had an emergency where our ac wasn't working the night before my wife's baby shower with family staying from out of town. Anthony came out at 11:00pm and fixed what was wrong! Literally saved the night on one of the hottest weekends of the year! Service: HVAC repair

A Quality did an excellent job with the new Trane Heat Pump and furnace. They were very prompt and efficient. They took time to go over everything from the new install. I highly recommend them to anyone that needs repairs or a new system.

A-Quality says it all, from the office staff, to Sean the estimator, and Paul and Brandon the installers. They showed up on time and wore COVID Protection and booties. Paul asked if I had any special instructions for them or any concerns and we discussed them. Next, I showed Paul the access route to the work area and they put drop clothes down. Paul asked again if I had any questions.

Then like "ninjas" they began to remove the old units and install the new units. Once they completed the work, Paul took me to new unit. He explained what they did, how it worked and asked if I had any question and answered all of them. Paul said to call them in the spring and they would come back out, because at 47F they could not start up the A/C. Paul walked me around the install and asked again if everything was satisfactory with me, quality cleanliness, etc.

I approved. It's all in the name "A-Quality, reasonable pricing and top notch work. I was a commercial construction contractor for over 40 years and had over 60 employees at times and Hats Off to Paul, Brandon and everyone at A-Quality Heating. Thanks for a Great job from everyone! Have a Happy New Year! Gary Houck at Finksburg, MD

We had our entire HVAC system replaced we got many many estimates and went with A Quality. They had the best price a great warranty and one of the best units you can buy. I can't say enough good things about this company, the two technicians who came out were polite they finished in about 4 1/2 hours which is great when you have dogs and you have to keep them confined.

If you're looking for an HVAC company I definitely recommend this one. I recommend staying away from the big names because they are more expensive. We were quoted a price twice what A Quality gave us and with them we got a Trane HVAC system which is one of the best you can buy.

Does the "A" Stand for Awful? My wife and I had a whole-home humidifier installed October 8, 2018 to prep for the winter ahead. My wife was 5 months pregnant and we have a grand piano that needs to be kept at a certain humidity level. Unfortunately, the tech who installed the system wired it incorrectly, never checked, took his money, and left. Fast forward to a bunch of nosebleeds and cracked skin later and we find out that the humidifier had never run once.

After I discovered this in January I called A Quality who sent out a different tech who indicated that the first tech did in fact wire it incorrectly; he said as much on this second invoice. This second tech fixed the problem, but when I called ownership the next day to express my concern about both my wife and the piano (in that order, of course!) the response was ambivalence and uncaring.

The owner admitted it was done wrong, blamed me for not calling sooner, and then tried to argue that the first tech did everything as per usual as he should (wired the system to the G-terminal, etc.) even though the owner then, in the same sentence, agreed that it was incorrectly installed. I was hoping he would try and make it right by offering a service for the system in the spring season or something, but instead I was told that, and this is a direct quote, "We give away more free stuff than ten other HVAC companies. It's sometimes easier to give away something for free than to argue with people." I guess since don't shout or curse or cause an enormous scene I was easier to argue with. (I also asked him, if his techs are so good, why is he giving away "more free stuff than ten other HVAC companies?" He didn't have a great response.).

In the end, I recommend Cool Breeze. They may be a bit more expensive, but they stand behind their products, do the job right, and are always available and on call. We had Cool Breeze install our condenser and heating unit a summer before this incident with A Quality and today I am very grateful that we chose them over A Quality. I work in the public school system. I give A Quality a D for Competence and an F for Customer Service.

Evan was very professional, kind, and informative. We used another company last year and was not happy at all with the service so we went back with A.Quality and will be staying with them for a long time!

A-Quality has always been very quick to respond to any issues that we have had on our geothermal system. Mike, our technician, was very prompt (on the weekend, no less), extremely helpful, fixed the problem quickly, and explained everything thoroughly. He is a real pleasure to work with!

Thank you A-Quality! My Elderly in-laws A/C went down this weekend. I called A-Quality at 845am and by noon their system was fixed! They had called other companies which could not come out for at least a week. You folks are awesome! D Katz Damascus.
