HVAC reviews in Glen Burnie, Maryland

MaxAir was not the first company we contacted to come help with a repetitive short-cycling issue that we were experiencing. While two other companies charged us high visit fees and left without any actionable solutions, MaxAir worked with us over multiple visits to figure out what was really going on and was able to resolve the "unsolvable" issue.

We cannot recommend their service, professionalism, and knowledge enough, and will be sticking with them moving forward for our HVAC maintenance and repair needs.

The tech did a great job. Came out on an emergency call very quickly and was able to fix my garage door in no time. I am so grateful!✔✔

Excellent fast service. I called that morning for the garage door at my job. the tech came out, assessed the issue, and a few hours later we were good to go. Thank you for the speedy, knowledgeable service. Thanks oncall-garageservice

Scammed us. Took payment, installed wrong equipment then never followed up with rest of work order. You call, no one calls you back. There’s no email or contact for the GM or anyone in leadership. Avoid at all costs because they’re overpriced to boot.

We scheduled a service for a day between 12-4. I received a text that morning stating that they "looked forward to seeing me". I called at 3:55 to check on status, and three more times up until 8:23 p.m. No one came or ever called back. When I called the following morning, I was simply told someone could come in the afternoon or the next morning. There was no guarantee that it wouldn't happen again.

When you rearrange your schedule for service calls, courteous service, or at least updates, are expected.

We had Blue Dot come out for an annual AC check. The AC was working the day before the technician came. Almost immediately he started talking about buying a new AC unit because of age. The technician also said a new capacitor could solve the problem. He installed the capacitor and said it didn't solve the issue. He continued with the high pressure sales tactics to get us to buy a new ac unit. We told him that we have to think about such a big purchase and how we would fund it. He seemed irritated and closed up the unit.
I eventually hired another company to look at the ac system. He showed me how the capacitor was wired in backwards. As soon as he fixed the wiring issue, the system worked flawlessly. He only charged us for the cleaning of dirty coils. How can I ever trust Blue Dot again? Mind you they installed a new furnace in January. How do we know that wasn't a simple and cheap fix as well. I was warned and didn't listen.

Update...I was sent an email asking me to contact their QC department. I did so several times. They never called me back. The only thing they cared about was the collection of a balance from a service membership. It's a shame since we have used them several times in the past and this is how they treat loyal customers.

2024 I purchased a maintenance contract that included an annual inspection. After a year with the contract, I tried to schedule my annual inspection. I tried two times. Each time I waited for them to show up, but they never showed. They contacted me each time after the promised arrival period and tried to reschedule. If they can’t even show up for an inspection, I doubt they will be able to show up for a repair. I just canceled my service contract.

Great experience today with Tiyese Pope. On time, knows his work, and explained current state of our heating system and why we might need some additions. No hard sell, just a factual rundown of what would make our system better. Will definitely ask for Tiyese again!

Very satisfied with BlueDot. Couldn't beat their price and benefits. They provide a transparent and safe transaction that made us feel safe and supported in replacing our HVAC system.

Chris Mathis was an outstanding technician. He was very knowledgeable and gave me and my wife clarity on our electricical system! He was real easy to talk to, professional, and would answer any questions I had!

Jesus Ocampo from GAC was awesome. He came out, quickly identified the issue with my furnace and fixed it immediately. He identified a few more potential issues with other parts of my unit and humidifier, provided me with some great ongoing maintenance options. I highly recommend this company for HVAC services.

GAC tech fixed our issue very promptly. He was quite professional and courteous. Highly recommend GAC for your GVAC needs. Terry

Scheduling an appointment was easy. A technician came. The very next day after the visit, I received an email asking to leave a 5-star review. I decided to wait until the estimate arrived. 11 days later, still nothing, even after I emailed the person who visited directly. And I am not judging the price, as I don't know it, and am not going to judge GAC's cost model. But at least have the respect for the customers who rearranged their schedules and spent time with you, and whom you promised to help.

The technician that serviced my home, Chun Shao, did an exceptionally detailed maintenance job. Chun was knowledgeable and answered all my questions throughly, explained everything, and provided honest advice. He profusely apologized for showing up almost 9 hours late because he didn’t have my address in his schedule. He was very respectful and we are so very grateful.

Separately, the scheduling and coordination needs severe improvement. I called at 8am and was told I was second in line. I later called at 4pm and was told the exact same thing. Neither were true.

Chris was friendly and straight forward. He gave me a solid ballpark quote (in spite of me not yet knowing all the details for what was needed out of my installation), a path forward to get more specifics, and a solid overview of what the installation would entail.
Excellent service!

I appreciate the utmost Tech and assistance did to inspect and maintenance work on my HVAC 10/17/25

GAC service is always top notch. Mr. Taylor was respectful, prompt and professional. He spent time speaking with me and explaining how to continue having my furnace be in perfect working order. I appreciated his time.

Wonderful service. They came the following day and fixed my furnace leakage! 5 stars all around for Ermias and Luis!

Matthew from GAC came in for a heating tuneup this morning. He was punctual, professional, and very thorough. He took the time to walk me through his process every step of the way and he highlighted things that might need to be taken care of down the road. Highly recommended.

We had the strangest problem that John Bennett figured out for us. We have a cool mist vaporizer near the intake to our furnace.
In a three week old filter, it got so clogged with chalky calcium powder that the unit was unable to maintain heat.
While we could’ve simply changed the filter ourselves, not knowing what the cause of it was would’ve had us changing filters every three weeks. Thanks to JOHN for his insight and for making us warm again!

Bruce and his team did a great job on the day of the appointment. He called letting us know he was on the way. He explained exactly what he planned to do (installing the generator) and provided good resposes to all of my many questions. We were extremely happy with the service he provided.
