I had an absolutely wonderful experience with Residential Express Heating & Air! As the weather…read morestarted getting colder this fall, I turned on my furnace only to discover that it was blowing cold air instead of heat. I knew I needed to call for service, but after having a less-than-pleasant experience with a previous home repair, I was a little hesitant about choosing a company. I reached out to several HVAC companies through Yelp, and Residential Express stood out right from the beginning. They were very responsive, answered all my questions clearly and thoroughly, even before I shared my contact information or scheduled an appointment. They were also very flexible with scheduling and willing to work around my availability, which I really appreciated. Robert was the HVAC professional who came out, and I honestly couldn't have asked for a better experience. Communication was excellent even before he arrived, and once he was here, he was friendly, patient, and thorough. He took his time examining the furnace and, although I had originally scheduled only a diagnostic visit, he was able to identify the problem and get my heat working again right then and there! Another thing I really appreciated was how carefully Robert explained everything. He walked me through what had gone wrong and the possible causes, and offered helpful guidance on what to watch for in the future and when to reach out for further assistance. I never felt rushed or pressured into unnecessary repairs or replacements. The pricing was also more than reasonable and completely transparent, with no hidden fees or unexpected charges. They even offered a discount for being a first-time customer, and I received the invoice by email, just as promised. From the initial communication and scheduling to the diagnosis and repair, the entire experience was professional, honest, and reassuring. It's such a relief to find a company that genuinely seems to care about its customers rather than simply trying to sell them something. I'm truly grateful to Robert and the Residential Express Heating & Air team for making what could have been a stressful situation such a positive experience. I would absolutely recommend them to anyone looking for reliable, honest HVAC service!

Highly recommend Philios and will definitely use him again for future plumbing work.

A+++ experience! Highly recommended…read more Cameron was excellent. He is a young technician with a great personality, very professional, knowledgeable, and thorough. He arrived on time, inspected the furnace carefully, disassembled the unit as needed, checked everything in detail, and took pictures throughout the inspection to show exactly what he was looking at and explain the condition of the system. Ashley was also great to work with. She made scheduling extremely easy, was able to coordinate a same-day appointment, and even helped arrange service for another property on very short notice. The pricing was very reasonable, especially considering the level of service and professionalism. It is great to find a local company with knowledgeable, dependable, and professional people. I will definitely use them again and highly recommend them.

He was great about communicating what he was doing and worked for hours in the hot sun to get my unit back up and running. I really appreciate a company that stands behind its work and makes sure its customers are taken care of, especially when an HVAC emergency happens over a weekend. Both Carlos and Tyler went above and beyond, and I'm very grateful for their hard work and excellent service!

My wife and I highly recommend this company to everyone we know. Our condo neighbor above us used Frosty's as well for the replacement of their HVAC system last year (2025). Keep up the great work!

In a panic, I found the number to O'Neill Plumbing and to my relief, an actual human being (i.e, not an automated message) picked up the phone.

He also helped me restore water to the unit and wisely advised that it was safe to use water in the rest of the house without affecting the busted hose.

In scheduling an appointment, we were exchanging texts and I asked about a video sewer inspection and was told that The Irish Plumber doesn't offer that service. In texting back and forth, I got a text that said "It may be a better option calling a company with a camera to be honest". In my opinion such honesty is exceptional in the plumbing industry. So I wanted to leave this positive review. If I do need plumbing services I will have The Irish Plumber at the top of my call list. Thanks Kieran for the honesty and excellent communication.

We moved to a new home in Vienna last year, and recently our kitchen sink became badly clogged. I called Mr. Sa, and he was able to come out the very next day. He quickly diagnosed the problem and took care of it without any issues. Six years later, his prices are still very reasonable, and the quality of his service is just as excellent as I remembered. He's responsive, reliable, knowledgeable, and gets the job done right. It's great to know that after all these years, I still have a plumber I can count on. I highly recommend Mr. Sa to anyone looking for a dependable and reasonably priced plumber in Vienna or the Northern Virginia area.

It's a little amusing watching him work with his team because he's like a surgeon when calling out for a tool, joint compound, or a fitting and his team surgically hands him what he needs. Definitely recommend Sa's Plumbing and happy that's he's in our area to support our plumbing needs.

Juan is professional, knowledgeable, and genuinely focused on helping customers make informed decisions. It's rare to find a technician who combines technical expertise with such great customer service. If I had the choice, I would request Juan every single time. If you live in the DMV area and are scheduling HVAC service with Michael & Son, do yourself a favor and ask for Juan Martinez. You won't be disappointed!
