This past ice storm killed my Trane HVAC system. The system was old and not maintained very well; regardless, the situation was an emergency and AG Heating Cooling Duct Cleaning was the only business in the Alexandria area that responded immediately. Mark told me that the system was not patchable and after 17 years I wasn't surprised. He told me that they would send two quotes by the afternoon. I checked the prices for the quotes and they were very reasonable, so I made arrangements for the order. AG got back to me and stated that the unit was at the shop and they would be there the next day to install it. The install was on 29 January and the elements were not ideal. Mark and Melvin showed up and had the new system installed and running in several hours. I was impressed with the professionalism and teamwork of Mark and Melvin. Finally, Mark walked me through the inside and outside unit and told me to call if anything was not working properly. He was professional and courteous, and he stated that AG would be back in the spring to check that the unit was running properly (part of the plan AG offers to customers). I appreciate the professional and sense of urgency that AG Heating and Cooling (Mark/Melvin) showed me during this unprecedented weather event. I am impressed with this small company and plan to stay with them. Thanks AG Heating Cooling Duct Cleaning for making a bad situation easy--well done. read more

Terrific Experience! I'm not usually one to leave a review, but when credit is due, credit is due! I reached out to Antonio on Tuesday evening regarding our situation of melting in the warm air with no AC. I could survive ok, but the wife, no so much. Mike came out the very next day (before noon!) and was able to determine the issue in seconds. Thankfully, not the compressor unit. Mike installed a replacement capacitor and we were back up and running. After watching the gauges that he had connected to the outdoor unit, he could see the freon was low. Added some freon and now we're good to go. The whole time he was here, I stood outside with him watching him work and asking him questions. He was so willing to freely discuss what was going on, what to look for on the gauges, different possibilities of things that can happen with the unit, and so on. What a terrific professional all around! It's the exact way a service experience should be. Great job Mike and Antonio. Thank You for getting us back (especially the wife LOL) in the cool air............You made me look good for choosing you to handle our repair! read more

I recently had the pleasure of working with Mike, AG Heating & Cooling, and I couldn't be more impressed with his service! From start to finish, the experience was seamless and professional. Mike arrived on time, thoroughly explained the problem, and addressed all my questions with patience and expertise. He went above and beyond to ensure my HVAC system worked efficiently, and his attention to detail was outstanding. Not only did he complete the job quickly, but he also left my home spotless. He took great pride in his work and customer satisfaction. If you're looking for reliable, high-quality HVAC services, I highly recommend AG Heating & Cooling. They've earned my trust and will be my go-to for all future needs. Thank you for the excellent service! read more

This is a updated review since I used this company to repair my a/c oil leak last year. After first repair in last April the problem was not resolved, and then we waited two months for second fix in June. The communication process was not easy and comfortable. In this early July we began to use a/c again and find it is hard to cool down (i.e., it takes about 3 hrs to lower 2 degree above 80, below 80 it keeps running without significant impact). We suspect the coolant is still leaking and contacted Mr. Antonio Gonzalez for check. After one week, NO response is received and we have to find an alternative solution. We DON'T recommend it based on professionalism, honesty, and communication experience. read more

Our AC went out at 5PM on the evening before a BIG heat wave. PANIC! I looked into a lot of HVAC techs and Antonio responded first and said he'd send a tech out first thing in the morning (8AM) and no charge to take a look. GREAT! Mike came promptly at 8AM, was able to diagnose the problem with our older condenser unit, charged us a very fair price and got the unit fixed by 9AM. He did not try and sell us anything extra beyond the much needed repair. We are now relaxing in our nice and COOL air conditioned home while outdoors is 105 degrees. THANK YOU Antonio and Mike for literally saving us from very uncomfortable few days AND saving us lots of $$$. read more

I had a great experience with AG Heating & Cooling and just wanted to say thank you! From start to finish, they were professional, responsive, and a pleasure to work with. I communicated with Antonio through Yelp, and he was friendly, helpful, and quick to respond. Geraldo arrived right on time and was courteous and knowledgeable. He quickly diagnosed the issue and explained everything clearly, making the process smooth and stress-free. It's rare to find such a reliable and friendly team. Because of this great experience, I fully plan to use AG Heating & Cooling for all my future HVAC needs. Thank you again, Antonio and Geraldo. Highly recommend! read more

Technician arrived within the time that was scheduled. He went straight to work removing the old ac unit and replacing it with the new one. He told me before he got started how long the process would take. The quoted price for removal and install was the best one I had gotten. The tech was very professional and kept me informed as to what needed to be done. The unit I got was a split unit meaning it is a heat pump and also an AC unit. I only needed AC pump. He had to rewire furnace to accept it and install new thermostat, but it all worked out. The AC is working fine now. For the price and good service, I would recommend AG Heating and Cooling!!! read more

Service and communication are unmatched. They came and measured the areas on a Monday and full install was completed on that following Saturday. I was previously quoted $4,800 to fix my old unit and $10,000 to replace it by a different company. Working with AG I received a very comprehensive quote and then I was sent away for work. I was able to pick up where we left off and everything was done within a week. Mike (the HVAC tech) was amazing and was able to explain everything. His assistant (didn't get his name) was efficient and very polite. Install was a breeze. I can't say enough good things. I'm glad I went with them and would again. read more

Our furnace gave out during the holidays. They were able to come out Christmas Eve and take a look. They let us know our furnace was done and helped us order another one ASAP. There were delays with the furnace manufacturer due to holidays and snow, but even then AG heating and cooling came out to try to trouble shoot our furnace for a temporary fix while waiting for the new one to come in. Once our furnace came in, they installed it ASAP. They were reliable, patient, helpful, responsive and empathetic. I will definitely call them out with any future needs and would highly recommend them to anyone that has heating or cooling needs. read more

The minute I made the inquiry on-line for the heating service, among other 5 services companies Antonio was the first to contact me. He had the knowledge and patience to resolve the issue with my furnace control board. He understood that I had a prior diagnosis done from another company but the work was never completed. Based on the furnace information provided, he was able to obtain the correct part quickly and the work was done within my budget the very next day. The whole experience was absolutely remarkable and satisfying that I told Antonio I will definitely contact him to perform my AC maintenance in Summer. read more

I recently had another great experience, thanks to Yelp with AG Heating and Cooling. I reached out to them yesterday evening around 2:30 because my air conditioning wasn't working properly, and the temperature was in the 80s. Within just 10 minutes, they responded. What's even better is that they don't charge any diagnosis or trip fees. The service technician was fantastic. He explained everything clearly and effectively, was extremely polite, and upfront about the repair price and process. I especially appreciated that he asked for permission before starting the job. Overall, it was a great experience read more

I came home to a non functioning HVAC. It was Saturday after 5pm. I was ready to find a hotel as my animals were over heated and my elderly mother was visiting. I started a search for service and was preparing to pay for a hotel for a few nights. I was thrilled AG responded to my request within 30 minutes. The tech arrived as schedule, he was professional and figured out the issue, made the repair, checked all my system levels, reset my system and cleaned a few coils. There was a fee for a weekend visit but we'll worth the cost and certainly less than a hotel room for the weekend. read more

My request for a service quote was quick and detailed. The scheduling of an appointment was quick and the technicia'a arrival was on time. The price for service was as quoted without any hidden fees. Mike, the technician explained everything he was going to do before he did it and he answered all questions thoroughly in an easy and understandable manner. He wore shoe protectors in the house and a face mask at all times without being asked. Very professional and thorough. I would recommend AG HVAC to all. Very positive experience for first time customer. read more

I have a rental property in the Baltimore area and the tenants informed me that the air conditioning was not working. After contacting AG Heating & Cooling, they had a technician at the house within an hours and the air conditioning was repaired in the next two hours. The tenants were extremely impressed with how quickly the matter was resolved and I was impressed with AG Heating & Cooling's responsiveness and speed. And there was no diagnostic fee to come out and assess the problem. I will be sure to use AG Heating & Cooling for my HVAC needs going forward. read more

Last Monday 04/07/25 my HVAC system was replaced. My appointment was scheduled for 8:00am. Antonio and his assistant arrived early, which was very impressive to me. It was a rainy day so they would have to trek through a little mud, but they came prepared with blankets to put down so my carpet wouldn't get dirty. They immediately got to work. They were very professional and I got a good price. I would recommend AG Heating & Cooling to anyone looking to replace or repair their HVAC system.. Top Notch company and worthy of a 5 star rating . read more

AG Heating was super easy to work with. They showed up on time, did a full replacement of my old R‑22 unit with a new HVAC system, and everything was done quickly and professionally. I got quotes from a few other companies, and AG's was the most comprehensive and still the best value for the quality of work. They were honest, didn't try to upsell me, and explained everything in plain English. Really appreciated that they handled the warranty registration for me after the job was complete--one less thing to worry about. Highly recommend! read more

After being stood up by my usual go to company for AC maintenance and repairs, I called around and got someone on the phone immediately with AG. He originally said someone could be out within 1-2 hours (which was perfectly reasonable) then texted and said someone was in the area and could be there in 30-45 minutes. The tech Mike was right on time, super courteous and explained everything thoroughly. He had my system up and running within 30 minutes. Will def be reaching out again for all my service needs. read more

We requested a technician to come out and fully expected to wait until the holiday weekend was over. To our surprise, Antonio arranged for a technician to come this morning to repair our HVAC compressor for our AC system. Responsive, reasonably priced, and friendly service will ALWAYS get my attention and respect. Grateful for solid customer service today and we have requested a quote to replace our aging system. read more

My heat pump outside unit started making horrible noises when the heat was turned on this season. They were quick to respond to my request for service and did not require a travel or service fee. Mike, the technician, was very knowledgeable and able to perform the repair. He was also "in the service window" both times - which can be rare these days! Would definitely do business with this company again read more
