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. He is very thorough and does extensive testing after the work is done to make sure everything is in proper order. I would highly recommend Cool On to anyone needing HVAC service.

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.

One of my two AC condenser units that cooled our bedrooms and loft stopped working last night in…read morethe midst of a heat wave right before the July 4th holidays. Thankfully our other AC kept working so we all slept in the living room while we waited for the morning to come to call around for HVAC companies that could come ASAP. HVAC Direct was the first company I contacted and Scott came within an hour of the call and got to work right away. And within an hour he diagnosed and fixed the problem (luckily just a shot capacitor) at what I thought was a reasonable price. Scott was super professional and friendly without being pushy with any additional products to sell. He also checked our other working unit just about of precaution. So grateful he was able to come and fix things so fast on the eve before a long weekend in the midst of a heatwave. Would def recommend HVAC Direct again to anyone and would use their business again!

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!! Highly recommend HVAC Direct Heating and Cooling!! Great Pricing for Service Plans & Parts, Excellent Technicians!! You can't go wrong with Joe K. & Scott at HVAC Direct Heating & Cooling!! 5 Stars*****!!!

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.

Barry from Powell & Turner stepped outside and looked at the flue and noticed the bottom cap was missing. He then proceeded to do an incredibly thorough examination of the oil furnace and identified a part that will need to be replaced in the future. He explained everything that he was doing and was patient with our questions. I feel confident that my furnace is in proper working order ... something I haven't felt in the past few years. There even was a discount for new customers. I will be using Powell & Turner for all my HVAC needs from now on and am glad I found them.
