I own a condo in one of the older buildings in Washington DC. I had a HVAC unit for 2 years with no issues. After 2 years the cooling stopped working. My building HOA highly Recommended KW Smith and Son. They came out and installed a new unit. I voiced my concern to the technician to ensure the water discharge line for the AC was exiting thr condo (as my neighbor above me had water damage from their HVAC leaking into their unit). He confirmed that he installed it correctly. A month later my tenant noticed water damage in the unit (floors were soaked). KW Smith came out and "fixed" the problem. I then had to go through their insurance to get the floors replaced which ended up being an insert hassle. KW Smith kept refusing to disclose the contractors estimate to fix the floors while their insurance wanted me to settle on an amount. Finally I went directly to their insurance and got the correct information discovering they were trying to get me to settle to an amount $3k less than what it would cost to fix the floors Fast forward to August of 2022. My new tenant let me know that my new floors were looking odd. After inspecting the floors I noticed that there again is water damage. After calling KW Smith they told me this is my fault because I have not maintained my unit two times a year (they never informed me of this requirement. As stated above I had a previous HVAC system in there for 2 years, never maintained with no issues. From the last interaction with KW Smith I am exhausted with how difficult they were and have decided to have my insurance deal with them. They offered to come out and look at the unit, however at this point I don't trust them and have gone with another company. Bottom line, don't trust this company. They come across as "knowing" what they are doing but they don't. This has been a nightmare. I am pushing to have my HOA remove them from our Recommended HVAC company list. I was hesitant o make this post, but after my last interaction with them I feel that it's my duty to warn other potential customers. This has been a complete nightmare.

The best in the business. They are absolute experts, and are 100 percent trustworthy, which I really value. They don't make things up and do everything they can to keep the costs down. One time it turned out that the issue was insignificant; even though, they were there for an hour they did fixed it for no charge. It is a wonderful family establishment. I have used them for multiple properties throughout the years.

In one word: Excellence! I have a large and complicated air conditioning system with many separate units, but this has never been a challenge for KW Smith. Their employees are some of the most competent, responsive and fair people I have ever had the pleasure to work with, including the expert technician, Jay, and the outstanding Melinda and Marvett. If you want a headache free experience with a company who actually knows what they are doing, I highly recommend KW Smith.

KW Smith has provided us with excellent service at both residential and commercial locations. At both sites they advised to save money others encouraged us to spend and drafted a plan to maintain our equipment that has resulted in great performance and lower costs. There is no one else I would recommend for your home or commercial HVAC needs.

I have used KW Smith for seasonal HVAC check-ups. They are always thorough. When I had a problem, they sent a technician out the same day. Furthermore, they are a pleasure to deal with. I've no hesitation in recommending them.
