HVAC reviews in Baltimore, Maryland

Jason was an amazing technician. He took his time to determine what the actual issues were and clearly explained what we needed. He did a thorough review once he finished his work. This was a great experience considering the problems we had to endure. I will ask for Jason any time we need future services.

Josh came same day and was able to replace the outside HVAC unit motor next morning. He was professional, knowledgeable and kept me updated on his work throughout. Very impressed and will keep using his services in the future

Jason was able to diagnose and fix why our brand new Bosch unit was not heating. A cracked igniter. Dealing with Jason was a pleasure but dealing with the AI answering service for At Your Service is not.

We’ve been trying to get in touch with At Your Service about an AC repair that started on June 6. Your team said a new unit was installed, but after daily calls with no response, we didn’t hear back until June 25—nearly three weeks later. A technician came on June 27 and guaranteed the job would be finished that day, but they left at 4:30 with no explanation and haven’t returned. Since then, we’ve been calling with no response and no resolution. We paid 12,000 for a unit that is not working.
Please reach out to us immediately. We just want this issue resolved.

Furnace need servicing. Josh initial saw there was no power to furnace and a part needed immediate replacement. Easy as pie, within 2-3 hours the job was complete. My home has radiators. He blessed system. Very pleased with the work. We call again if ever in need

I looked on angies list for someone to fix my boiler, I got a call in one minute after, it was the owner, he listened and sent a technician the next day, he sent Josh Tyler, I got a text with appt info and a pix of the person coming, nice touch. I knew the other hvac company was trying to take advantage of me, THIS COMPANY DIDN'T DO THAT, they are professional, timely, and know exact what they are doing no games. My technician that came again was Josh Tyler and he really knows HVAC. He took his time and looked over everything before explaining what would happen next. Thank you so much At your service, you have a customer for life. And Josh thank you.

Not getting heat distribution through the house and wanted to knnow what was wrong and how to fix include an estimate. Jason came over andd was very polite and professional. His knowledge of our heating system and his advice on how to fix or replace was thoroughly explained. We are waiting to finalize the estimate.

Jason was a great help showing me how to effectively clean my filters. So they can be done every 3 months instead of waiting every 6 for service calls. Very polite and also very thorough.

You’ve lost my loyal business—not because of the quality of your work, but because of increasingly poor communication and inconvenient scheduling.

We hired your company to install a new home HVAC unit, which has worked well, and we’ve relied on you for nearly three years of maintenance. Unfortunately, the past year has shown a noticeable decline in service, with unreliable appointment commitments and your AI phone rep, “Sarah,” providing inaccurate or unhelpful responses.

Today was the final straw. We had a scheduled maintenance appointment and were completely no-showed. Naturally, we called throughout the day to find out if anyone still planned to come. Each time, “Sarah” told us someone would call back, yet no one ever did. It’s clear the AI cannot confirm technician availability, and your company needs to take responsibility for relying on a system that provides misinformation. When customers plan their day around a scheduled appointment, you should at least have a real human available for same-day escalation.

Even beyond the AI issue, your human-scheduled appointments have become just as frustrating. Our most recent maintenance visit came with an 8 a.m. to 4 p.m. window, with no narrowed time frame until the morning of the appointment. I’m fairly certain your windows used to be more reasonable—this feels like a recent change in policy or management. It couldn’t have always been 8–4, because I would have noticed that long before now. You’re essentially asking me to commit an entire workday to a relatively short appointment, and that’s unreasonable. Most service companies provide a three- or four-hour window, and even those that book full-day ranges usually narrow it down a day or two beforehand. It shouldn’t be this difficult to schedule responsibly—especially for a company that seems increasingly dependent on automation.

To make matters worse, this missed appointment was part of a prepaid service. After this experience, I no longer want the service at all and will be requesting a full refund.

I first used At Your Service in Fall of 2024 to replace my heater. At the time, they were very responsive, scheduling an appointment quickly. I thought they seemed expensive, but the technicians seemed genuine and trustworthy.

In Spring of 2025, I had them replace my AC. They also convinced me to switch over to their thermostat. That's when things went downhill. The technician left a hole in a wall that they said they would come back and fix. They never came back to fix it. My property management company has tried calling frequently since then (for several months ago) and no one has ever gotten back to us. I've also tried via calling, contact form, and chat. It seems they may be using an AI receptionist to answer the calls. They always say that they'll leave a message and that someone will call me back, but no one has ever called me, or my property management company, back.

Even worse, a few months later, the AC has stopped working! It's crazy that I paid tens of thousands of dollars with this company only to be ghosted.

I had the misfortune of not only dealing with a leaky HVAC unit that damaged my ceiling but also an incompetent contractor with At Your Service. If you’re reading this before you call them, don’t bother. If you’re reading this after, then cry a little over what you’ve spent but don’t give in to the sunk cost fallacy and look for someone else.

About 2 months ago in midsummer I had called AYS because they offer emergency services, especially in peak seasons. I had to get through a frustrating phone call with an AI chatbot who can only take messages and can’t transfer you to a real person, but quickly got a call back and a technician over to resolve the issue. I paid over $900 for the repair, a failsafe system, and a warranty if it were to leak again, in addition to a few hundred dollars to repair the ceiling separately.

At the time I was satisfied with their service, however as I was out of town was not present for the repair while the occupant of the unit was. That was until I had to call them now 2 months after they did the work to fix the same exact issue. This time however, over the course of 4 days I called and left messages after they had no-showed an appointment their AI chatbot “confirmed”, leaving us without AC for that time. When they finally returned my call and sent a technician out, I was told that the failsafe that they had told me was installed the first time around was not the same one that they did install, which would have caught the leak and shut off the unit before it damaged the ceiling again. Not only that, but the manager, Brian, tried to extort me for a service costing over $3k by having his technician tell me that he’ll give me their “top option” otherwise wouldn’t give a guarantee.

Ultimately the technician did the work and installed the missing sensor, but I will never again use At Your Service for any of my needs and I will tell others not to either. I doubt the work they did was even done correctly this last time and have reached out to other HVAC professionals who don’t spend their budgets on flashy advertising or useless AI bots to look at the system and for any further work I need.

Stay away from this company. They are absolutely terrible.

I got a cooling and heating system installation from this company last summer. The installation was a very frustrating experience - they installed everything and then claimed the system wasn't working because there was an issue with my refrigerant line, even though it was working fine the day before with my old system. They wanted to charge me another few thousand dollars to replace. After having to argue with them about how that didn't make any sense, they then tested the unit they installed and realized it was defective from the factory.

Now, a year later - I'm having more issues with the system they installed. I called them to schedule service since it's under warranty. I took a day off work to wait for them. They never showed up. I called the office and they told me they were on their way. Still didn't show up. I called again and then realized the entire time their office line is some AI robot.

At My Service.... yeah right! You can't even talk to them. They'll take your money and leave you with problems. Completely unprofessional. Hire a real company that hires real people.

Jason was super amazing with help with my old century boiler. He explained everything that my boiler would need to for repairs and I do plan on get that fixed next year. He even offered me there $31.99 policy for them to come out every 6months to check the HVAC and my boiler but I didn’t have the money for that today. He was able to get the boiler relit and now my daughter and I have some heat for the winter. I only had enough to pay for it to be relit. I did inform Jason to give me a call on November 1st so I can sign up for the policy. I really appreciate his help because I have been without heat for the past two weeks. He was such a great help.

I am very pleased with the work done by this company. The workers (Jason, Ryan & Jason) were friendly, professional and explained what was needed and gave options to fix the issue. Would recommend to others.

I am incredibly grateful for the exemplary service provided by At Your Service for cleaning out my air vent system. Ryan and Josh worked incredibly hard and diligently from the moment they arrived and explained what they were doing throughout the day. They were kind, courteous, patient and such hard workers. I am again incredibly grateful and very, very pleased.

I had a great experience with At Your Service company. Jason, the service tech, came out to perform HVAC maintenance and did an outstanding job. He thoroughly checked the heating and electrical components, explained everything clearly, and was completely transparent about the system’s condition and potential future issues. It’s refreshing to work with someone who’s both knowledgeable and honest. This company is definitely the one to go with, and I’ll be reaching out to them again whenever any issues come up. Highly recommended!

Had an emergency heating issue on the coldest day of the year and Jason came out to fix it within 2 hours! Some small wiring issue was quickly resolved and he made sure to check everything else was fine. Highly recommend him and this company for Baltimore city homes!

Josh did a wonderful job. He checked out everything and explained everything to me and gave me my options. He talked a little fast but I realized that that was something that he could not control. Actually it made me pay more attention so that I could understand everything better. He seems very competent at his job and we would have no problem having him back in our home. Happy new year and have a wonderful day.

Very pleased with At Your Service. Jason has provided maintenance for my units for the past two years. He is such a professional and really knows his stuff. I always learn something about my ductless units when he’s here, and feel very confident about the quality of his work. You can tell he really cares about what he does and that is sometimes rare these days. The installation crew was also very good. I hardly knew they were here and they were incredibly tidy. Highly recommend!

Jason arrived on time and was very friendly. I appreciated when he covered his shoes before coming into the home. Jason was efficient, professional, and VERY customer service oriented. He even received our outdoor faucet with the insulation cap! We are throughly pleased with At Your Serice and their technicians!
