EXCELLENT Based on 37 reviews Posted on Taha Taafroukt Amazing service came just on time and fix the problem I will definitely recommend to any one very professionalPosted on adil hasnaoui After my AC broke I had to consult A few companies but after a referral from an old friend I contacted Potomac HVAC. They showed up on time as promised, they are very professional. Mr. Mahdi was polite and knowledgeable he knows the Ins and Outs of almost everything that had to do with HVAC he explained the job to be done step by step and he took measures to everything including the airflow to the unit’s closet. They came next day removed my old unit and replaced it with a new one in less than a day of work, AC/ Furnace/ condenser… hoses pipes…etc. Mr . Mahdi came back next day to make sure again that everything was working properly and promised to visit again in the mid summer when it gets hotter. Their prices are lower considerably than other HVAC services. By the way they left the work area spotless. I am so happy With their work I would definitely consider them again and referred them only to my closes friends.Posted on Andrew Weiland Replaced a failing heat pump quickly. Helped me pick the right option at the right price for us. Also installed a smart thermostat and worked with Carrier to iron out any issues. System is now working better than before!Posted on Azeddine Zaki I had one of the best experience with Potomac HVAC. Our Heat stopped working in the middle of the work shift . So I was waiting to close the restaurant because it was like under 39 degrees. I had to call 5 companies to come and look if they could help fixed it back . No one was able to schedule the same day appointment except Mahdi. Very knowledgeable about his job , and paid attention to every detail. I was so happy with his high quality work and his excellent problem solving skills . I will always work with him , and recommend him to all my friends and family .Posted on Mahyar Imanian I recently had the pleasure of working with Potomac HVAC for the installation of a new HVAC system in my home, and I couldn't be more satisfied with the experience. From the initial consultation to the final installation, the team demonstrated utmost professionalism, expertise, and dedication to customer satisfaction. What stood out to me was the thoroughness of the consultation process. The technician took the time to understand my specific needs, considering the size of my home and my energy efficiency preferences. They provided clear, detailed explanations of the recommended systems, helping me make an informed decision without feeling pressured. The installation process was equally impressive. The team arrived on time, worked efficiently, and maintained a clean work area throughout the project. They went above and beyond to ensure the system was installed perfectly, even taking the time to walk me through the operation and maintenance of the new system. The customer service provided by Potomac HVAC was exceptional. They were responsive to my questions and followed up after the installation to ensure I was completely satisfied with their service and my new HVAC system. It's clear that they prioritize customer satisfaction and quality workmanship. Overall, I highly recommend Potomac HVAC for anyone in need of HVAC services. Their professionalism, expertise, and commitment to customer satisfaction set them apart. I'm confident in the reliability of my new system and comforted knowing that I have a trustworthy company to call for any future HVAC needs.Posted on South Lynn Great servicePosted on Amy Hollis We had a great experience with Potomac HVAC. We reached out to them during very cold temperatures when our heat pump suddenly started shaking and were worried we would have no heat for the night. They responded immediately, communicated great, and fixed the problem all within an hour. Definitely recommend!Posted on Peter Hmel When our heat pump decided to sound like a sleigh bell gone rogue in the middle of December, I panicked. Visions of a freezing holidays and frosty mugs of cocoa danced in my head. But thank goodness I was referred to Potomac HVAC by my neighbors. From the first call, everything was a breeze (pun intended!). Mahdi was able to come take a look within an hour of me calling. After discussing the options, he came back the next day with the replacement parts and had us quiet as mouse not stirring the night before Christmas. Not only was Mahdi skilled, but he was also friendly and patient. He explained everything clearly, answered all my questions (even the silly ones), and left the work area spotless. Seriously, the only evidence he was there was a perfectly quiet heat pump and a grateful homeowner.Posted on William Muia Mahdi was very responsive and professional. He was extremely conscious about taking his shoes off and keep the work area clean. I would definitely use him again.
