His pricing ended up being more competitive than several of the larger companies I received quotes from, and Ricardo did a better job at answering my questions and explaining the thought process behind his recommendations.

This man will hustle and break his back to earn your business and build a relationship with his customers. He takes pride in his work. I cannot recommend this place enough. On a Friday afternoon, I reached out to ~5-7 vendors to assess a broken HVAC in a DC condo. Ricardo was able to come out IMMEDIATELY at 8PM on a Friday night. He did a quick dusting of the unit which hadn't been serviced in a while and even went to the roof as a part of his diagnosis. After sticking around for a couple hours trying to find the source of the problem, I was mentally preparing myself to pay a diagnosis and service fee, but there was no such thing. What signaled to me Ricardo was top notch was the fact that this man lives in Baltimore, easily a 50-minute commute from where I was in DC. He didn't leave until I was satisfied with his work until 930PM on a FRIDAY night. This type of service is difficult if not impossible to find. Ricardo patiently explained what the problem was, why I wouldn't have working AC after he would leave, and what my options were. He was very transparent with pricing, sent over a couple of quotes, and laid out what install schedules would look like depending on which manufacturer I went with. He and his team came in Tuesday and the install lasted about 7 hours. Fully working AC in less than 2 business days at a reasonable and competitive price. You cannot beat that.

My husband contacted HVAC Direct Heating & Cooling after normal business hours concerning our A/C…read moreunit at our personal residence was ONLY blowing warm air!! Now the previous evening, my husband contacted a large local competitor to check our HVAC system. Technician from local competitor came out and looked out HVAC system, didn't test any components and stated "our compressor was locked & leaking refrigerant and quoted my husband $6k to replace it or we can purchase a brand new HVAC system for $25k!!!" (NOT TRUE!!!). The tech even left our outside power switch unplugged so we couldn't test the system!! SMH!!! We won't contact them for any service ever again nor recommend them to any neighbors, friends and family!!! Joe K, Service Technician at HVAC Direct Heating & Cooling contacted my husband within 20 minutes of him contacting the office the next business day and scheduled a visit that evening. He came out to the house, checked the compressor and quickly diagnosed the capacitor as the problem & replaced it. And Joe K. even showed my husband how he diagnosed the capacitor as the issue NOT the compressor leaking refrigerant as stated by local competitor!! No refrigerant leaking at all!! Compressor in good condition!! In addition, Joe K., checked the wiring, fan, all associated parts and cleaned our a/c unit. No issues at all!! Just some cleaning needed!!! HVAC in excellent working condition AGAIN!!! In addition, he checked our furnace, cleaned some our internal components and showed my husband some DIY things to do to maintain our HVAC system throughout the year!! Amazing work & Professionalism by Joe K!!!! I returned home from business travel to a COOL & COMFORTABLE HOUSE!!! ALL Work completed in an HOUR!!! (less time than the large local competitor spending 2 1/2 hours trying to sell my husband a new HVAC system)!! Joe K. was amazing, excellent communicator, knowledgeable and very professional!!

I initially thought about taking off a star because John arrived outside of my appointment window,…read morea pet peeve of mine, but then I remembered a few things: he came on a Sunday, on less than a day's notice, Arlington is very far from Upper Marlboro, the appointment before me went over, which can happen to anyone, and most importantly, small businesses are the backbone of America. John was very polite and immediately told me my HVAC closet smelled because a mouse died in there. He also called a relative while at my place and on the way home to give me their suggestions on dealing with the smell, which has nothing to do with HVAC and is above and beyond in my opinion. Yes, I did have to pay the $100 fee to come out. I paid in cash to not have to pay the 10% processing fee. I was fine with paying this to have someone come out so quickly, and on a Sunday. Would call again. When my problem actually involves HVAC repair.

After seeing several other companies and hear what they had to say and gave us their estimates we had to go with Mario and his team. They installed a Daikin unit with barely any wait time.

Unit comes with 12 year parts and labor guarantee which is the best deal out there. They didn't have the unit I ordered so the manufacturer upgraded my unit for free. Great first experience. PS 4 weeks later my house is actually cold and my house have never been cold. You have to give these guys a call. I had a question about the app and Mario called me back right away. Couldn't be happier.

I had another company come look at the problem 2.5 weeks ago. I called them in the morning and the showed up a couple hours later. After looking at my HVAC, they diagnose the problem as poor air flow due to a dirty air filter. There was a fine white powder on the filter which made it hard to see the dirt. The white powder is a result of using a ultra sonic humidifier with tap water. They suggest to change the filter more often (every 30 days) and buy a different brand filter with a MERV 8 or 10 rating.
