Mike w/ AG Heating & Cooling and his partner were great! They arrived on time and replaced my 35-year old system per our agreed Statement of Work & price. I will definitely reach back out to them for any future HVAC needs. Highly recommend! read more

Very quick to respond, no service fee inspection. But cost for service is questionable. Replace capacitor and fuse $$$

They responded quickly, were at my house within a few hours, and were able to fix our system with a relatively inexpensive part. Would happily call them again. read more

It's been almost a year since AG installed a new HVAC and it is still running great. They just came and did a courtesy maintenance check and everything is working great. Best value and service - so glad I went with AG ! read more

AG Heating and Cooling installed an HVAC system for my father last year. Unfortunately, the system is not working properly this year, and I have had a very difficult time getting any response from the company. I have tried reaching out multiple ways, including email, Yelp message, phone call, voicemail, and text message, but have not received a response. I understand companies get busy, but when a recently installed HVAC system has an issue, I would expect some level of follow-up, especially if warranty service may be involved. Based on my experience, I am disappointed with the lack of communication after the installation. The initial work may have been completed, but the lack of response when a problem came up has made it difficult to recommend them. read more

REVIEW UPDATED: AG Heating and Cooling was initially responsive and offered a low price on a quality water heater back in December 2025, when my water heater broke. Everything seemed to be working well. However, the work they conducted included the use of a substandard part which recently failed, and the improper installation of the expansion tank. While they offered me a very good warranty on parts and labor, as they are no longer operating their business, I cannot hold them accountable for the substandard work. I understand they've had to close their business for family reasons, and I'm sympathetic to why they can't fulfill their warranty, it does not change the fact that they initially did substandard work, or that I'm having to pay a different plumber to repair it. If they ever reopen their business and are able to compensate me for the repair work to correct their mistakes (that should have been covered under warranty), I'd be willing to update my review (again). read more

I strongly recommend AG. Our heater woke us up with a buzzing noise and electrical smell at 5 am. It was a little unnerving, especially with the polar temps we've been having the past few weeks. Antonio responded very fast on the app and he got a repair person out within a very short amount of time. The repair was taken care of very quickly and at a reasonable price. No muss, no fuss, just a straightforward interaction and now it works better than it did. We will definitely use them again! read more

Hard to reach. Called the number for AG Heating and Cooling, (240) 334-8613, at 2pm on a Tuesday to schedule an estimate for a new HVAC heat pump system. I got a voicemail greeting that said "Please leave your message at the tone. Mailbox full." It was possible to generate an SMS request for a call but no way to say why the call was requested. read more

I 1000% recommend AG Heating & Cooling for your HVAC needs. I needed to replace my old unit as it was in bad shape and stopped working. I contacted them, they gave a very reasonable quote and then came out the next day to install. They were quick and efficient and had everything completed in less time than I anticipated. I will definitely be using them for my future maintenance needs! read more

When our family moved into our home a couple of years ago, we were told that our HVAC system would need replacing "soon," as it was pretty old. We had previously brought out AG Heating & Cooling to refill the refrigerant for our AC unit, as we weren't ready to do a full system replacement at the time. However, we decided a few weeks ago to move forward with replacing our system and reached out to AG H&C -- along with several other companies -- for a quote to replace our AC, furnace, and coil. Antonio was quick to respond and was able to answer all of the questions I had about the project, including specifics on the equipment his team was planning to install. All of the communication was done via text/chat, and everything was made clear from the beginning. We scheduled an on-site appointment to finalize the quote (to ensure there were no unique circumstances with our furnace/AC) and were able to schedule the day of work once the final quote came in. I received several quotes for this project from different companies and found AG's to be the most reasonable and clearly explained. The team did a great job on the day of the project. They arrived on time and worked through most of the day to complete the installation. They took good care of the property throughout and walked me through all the relevant components at the end of the day. Payment was easy, and the team was gone well before 5 p.m.! I'd recommend the AG Heating & Cooling team to anyone looking for clear communication, reasonable pricing, and thorough work. Thank you, team! read more

They wanted $2,995 for the motor and circuit board...or $6,000 for a new A/C unit. We called the company who installed the A/C unit...they charged $200 to replace the motor and now the A/C works fine. AG may be responsive and fix the issue but they may fix more than necessary and make you pay for the unnecessary fixes. It's like replacing the alternator, starter, and battery (or even replacing the entire engine) of your car when you only needed a new alternator. read more

I requested installation of a new HVAC system in my attic. AG Heating and Cooling came in with a detailed, fair and reasonable estimate and I accepted. Now, here is where things got crazy. As a frustrated owner of an older home, I have been experiencing the crazy, crazy cost of high energy bills from an older out of date HVAC system. My first thought was to buy a system that was larger with multiple speeds offering the highest SEER rating in hopes of bringing those bills down to normal. To make a long story short, I ordered the wrong system and ended up having to buy a second system that actually fit my space and current construct. AG came in, gave recommendations and replaced that old system with the new system as requested. AG went above and beyond to ensure that I was up and running as soon as possible. We still have a few things to do to get the efficiency where it needs to be. Trust and Believe, AG will be my go-to HVAC specialist team moving forward. Big shout out to Mike and Jose for the AWESOME work they did. Another shout out to Antonio for being patient with me and explaining things as needed. read more

5 stars all around! I got a full HVAC change in my townhome and the process was easy from beginning to end. They texted with me to give me updates and to schedule a time for a tech to come out. They were flexible with my time and were on time in the morning to do the work. They finished early afternoon on a Saturday morning leaving time to take the kids out. The product looks great, indoor and outdoor units and the tech communicated effectively from beginning to end. They were priced competitively, other companies quoted me 4-5k higher for the same work. Highly recommend! read more

My (admittedly very old) gas furnace is struggling to keep up. The unit sometimes runs the fan with only the pilot light going. I hoped cleaning the flame sensor (as part of a professional cleaning) might fix the problem. AG Heating and Cooling was the first business to respond on Yelp. They offered to do a professional cleaning at literally 75% less than the other estimate I received. The technician arrived at my door slightly late (40 minutes after the scheduled time), but completed the job quickly, professionally, and for exactly the quoted price. I would call this business again. Unfortunately, the cleaning did not fix the problem and the only other alternative offered was a new/replacement heater. I really miss the days when appliances could actually be repaired instead of just replacing them when something major goes wrong. read more

Great service and communication. They were dedicated to solving my ac issue and they were prompt to do so. Highly recommend and great value. I will be using them for annual maintenance read more

AG Heating & Cooling were the most honest and reliable HVAC technician I have ever met. Greatly appreciate their timeliness and professional work they conducted with our heating issue. Will definitely be reaching out to them if I'm in need of HVAC services in the future. read more

I had HVAC (cooling) issues with my HVAC heat pump unit. AG HVAC sent Gregg to diagnose what was causing the cooling issue. Gregg found what was wrong and AG HVAC company DID NOT charge me any fees. They quoted me for a repair. Then I asked for a quote to replace the whole units. AG HVAC company gave me a quote that was very reasonable. Mike and Dave showed Sunday @ 0800 to replace my entire HVAc unit (inside air handler and condenser unit outside). They were knowledgeable in what they do, courteous and great people that you can have a conversation. I am very satisfied with the job they did and I personally recommend and this company. Very sincere people that are not looking to make a quick buck but to help you! read more

We just had a completely new HVAC system installed by AG Heating & Cooling. Everything was fantastic. Price: They provided the cheapest quote of any company and I received a free upgraded unit due to manufacturer limitations on the model I wanted. Communication: superb response time and clear answers to all my questions Service: They did a great job installing the system. Everything works phenomenally and they have follow up appointments every 6 mos for the next 2 years. Very happy I went with this company. I SAVED a lot of money and couldn't imagine any better service. read more

They were prompt and responsive as they had a technician out the next day to fix my heating issues in the morningr. The technician was friendly, and explained things throroughly. No issues at all. read more

When our AC gave out, AG Heating & Cooling was quick to respond--they had a technician at our place the same day. He inspected the system and tried a few things to get it running again, but since it was pretty old, none of the fixes worked. He suggested replacing the unit, and after we agreed on the quote, things moved quickly. The tech arrived right on schedule and jumped straight into the installation. Before starting, he walked me through the timeline, which was really helpful. Throughout the whole process, he stayed professional and kept me informed about what was being done. We went with a split unit (AC and heat pump combo), and everything's been working perfectly since the install. The price was fair, the service was great, and I'd definitely recommend AG Heating & Cooling to anyone needing reliable HVAC help. read more

They did an AC replacement for us. They were fast and Mike was very polite and thorough, explained everything he was doing and helped us understand it. read more

I made an appointment 6 days in advance. They did not show and did not contact me. When I contacted them, they offered to come during a window later in the day. They missed the window and did not contact me. When I contacted them, they said the tech was 5 minutes away. The tech got the AC working rather quickly, then said our thermostat was bad, pulled out all of the wires from the thermostat and connected them all together. Ac stopped working and tech said we had bad electricity that had shorted out the Ac's electrical board. He said he had the serial number and they would order a new one for me. This seemed fishy. The next day, when I heard nothing from them, I contacted them and they said they were waiting to hear back from the manufacturer. That was 8 days ago. Meanwhile, because I did not trust what the tech had told me, I had another company come out. They had the AC up and running in 5 minutes, then did a bunch of checks on the system to be sure everything was ok. It was. No new parts needed. AC has been running fine since. I would not use this company as their communication is horrible, they don't seem trustworthy, and they incorrectly diagnosed the problem saying it needed a costly repair it did not need. Update: Since this business said I was not telling the truth, I added the texts I had with them. They should have just responded "With the extreme heat, we are overwhelmed with people needing service. We are sorry that we were not able to meet your expectations." Most people might have given them a pass on this incident. Instead, they said my review was not true which, when you look at the texts, just makes them look less trustworthy. read more

The owner was super quick to respond to my messages. Also gave me a very detailed quote at an unbeatable price

Appreciate the very quick response from Antonio even when I reached out to them after hours. A repair person came early the following day to fix our AC unit and did a very thorough analysis of what's wrong with our AC. Very friendly and professional- we highly recommend AG Heating and Cooling. Thank you much! read more

I wish I could rate this better but I've had issues since the installation that have not been that still need to be resolved. All of my emails, calls, and texts have gone unresponsive. I had a/c unit put in June 2024. I had a furnace put in May 2022. The A/C unit doesn't push out enough air throughout the house like my previous unit. My furnace also now does not blow hot air. This was a very frustrating situation when I had a favorable experience with this company in 2022. read more

Excellent company this is the second time , I request their service . They install my compressor this time . Excellent service , fast service , best price . Best communication . read more

Two technicians came out on a very hot day to replace our old AC and furnace. They did a great job. At the beginning I was worried whether they were able to handle the new variable speed system. It turned out I was worried too much. They were apparently competent for their job and finished in one day. They also addressed our questions and taught us how to use the thermostat. We really enjoy our new AC. Their price is also reasonable. Highly recommended. read more

Once the machine was installed the technician ran sever test and since I wasn't home sent several videos of what was happening.

So glad I went with AG Heating & Cooling. I hired them to do a routine check of our heating system. Pedro was friendly, professional, punctual, and knowledgeable. Excellent price, too. I've found my new go-to company. read more

Great service and pricing. On time and very knowledgeable to the service needed. I would definitely go with them again

Our ac units suddenly stopped working at 9pm, and after a terrible night of sleep in this heat wave, I sent out a repair request at 6am the morning of July 4th, but not getting my hopes up since it was a holiday. AG responded almost immediately and their prices were very reasonable. The tech arrived on time and was able to efficiently diagnose the issue, repair what he could, and advise us on our next steps. Because of his findings we found out the main issue lies with Pepco (of course), and we were able to get them to come out to fix our power supply, and now our AC units are running again. Really grateful for their prompt and excellent service, especially during a holiday, would highly recommend them for all HVAC emergencies! read more

When our AC broke down someone else told us repairs would cost nearly as much as a full system replacement. However, we didn't feel like this was quite right and the idea of replacing a system that was probably only 7 years old didn't sit well with us. So, we contacted AG Heating & Cooling and they showed up that day. Mike provided a thorough diagnostic, explaining what was going on and what he was doing to troubleshoot. After a bit of tinkering, lo and behold, the AC unit came to life and was working just as it always had been before. Best of all, their pricing is unbeatable. It was essentially the cost of what others charge for diagnostic alone (AG provides a free diagnostic). We've gone though several other companies and I'm so glad I've finally found my trusted technician. I can't recommend them more highly. read more

Found this company by doing a search on Yelp. They were the first to respond to my request, and the lowest cost operator. I had to wait a couple of days for a technician, but that wasn't an issue because this was primarily a yearly AC unit check up. The technician was terrific - very polite, took care to put on booties and mask, and then was very informative throughout the service call. He pointed out things I could be doing to improve the operation of my system, and showed me how to do basic maintenance tasks and explained why they would be helpful. I've never had a more thorough HVAC maintenance call. It makes me wonder what other companies did not do during their visits. Antonio was here 45 minutes and charged exactly what they said they would charge when I first contacted the company - no upselling, no hidden fees, etc. I thought he was very honest and knowledgeable, and I plan to contact AG Heating & Cooling the next time I need service on my HVAC system. Bonus is that this is a family-run company. I could tell he took pride in doing a good job. read more
