I recently had my first service visit with Cold Comfort, and I was very impressed. Jerry was the…read moretechnician who came out, and he was knowledgeable, thorough, and easy to talk to. It can be difficult to find honest and reliable HVAC companies, but this experience stood out. I had several questions prepared about my refrigerant, capacitor, and overall system, but I found that I did not even need to ask them because Jerry naturally addressed those topics during our conversation and explained everything clearly. He also completed a detailed inspection of my HVAC closet and offered a helpful recommendation for a better filter. The service was straightforward, with a flat fee and no upselling or pressure, which I really appreciated. Overall, it was a great experience, and I will definitely be using Cold Comfort again for my annual maintenance.

Our AC went out a little over a week ago, of course it happened toward the end of the week so it…read morewas Friday afternoon by the time we realized it wasn't something routine maintenance on our side would fix. Jary (who helped us when we first moved in) came out on Tuesday and said we had a leak somewhere since the closed-system unit was totally out of coolant. He came back Weds. to do the leak detection and found the leak, recommended a new coil. We had the new coil installed on Friday; this time it was Ricardo and team that did the work installing the coil. They did a great job and a couple hours later our house was back to normal temperature. Gabriel helped us with all the coordination and estimates and seeing if the part was still under warranty (it wasn't, but I didn't expect it would be honestly.) No one likes spending a bunch of money on repairs but I'm very confident that the recommendations Jary made were sound and correct. He did not attempt to upsell me at all, which is greatly appreciated. (The estimates Gabriel sent did include options for replacing the unit, but that wasn't necessary at this time and there was no pressure to do so.) I will continue to call them if we have issues in future with our HVAC system.

When the technician got here, he said the previous company misdiagnosed the issue, and all I needed was a new capacitor. He fixed it for a total of $335 and it works perfectly now. Very capable and honest people, they are now my go to for HVAC issues in the future.

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*****!!!

But I checked other rating apps where JDL did much better. I had a text chat with Amber, their office manager, and decided to try them. I was very happy overall. They were responsive in communicating and were able to send a technician quickly. Chris was well prepared, friendly, and efficient. He quickly diagnosed the problem (bad capacitor) and was able to fix it in a single visit. The cost was very reasonable. I would certainly use JDL again. Incidentally, for some unknown reason, my Yelp profile shows me as living in San Francisco. Actually, I am in southern Maryland.

I scheduled an annual service with Greenfox. They came out on 5/6/2026 and performed the service…read morefor what I believe was $99. They said everything was good to go - no issues. Two weeks later, on 5/18, the air conditioning stopped working. They market themselves as 24-hour, so I called 5 times that evening. They have a system for screening their calls. I communicated several times that this was an urgent concern, as I have 5 pets who would be intolerant of the 100-degree heat forecast for the following day. Even after dark, my house was 85 degrees. After those calls, I received no calls back. The next morning, on 5/19, I scheduled a morning appointment with Greenfox and then chatted with them via their chat system. The person on the chat assured me that this was a concern. They reported that they marked my appointment as urgent and would register a complaint with the company on my behalf. They assured me that the tech would leave and arrive at my house by 8am. 8am came and went with no call or contact from Greenfox. I logged on to the chat again and spoke with another agent and recounted everything that had happened previously. They said they could do nothing but make appointments on the chat. I said that I did that morning and was told the appointment would be around 8. They said I would have to call the office. I told them that I already had 5 times, and I received no return call. The chat said there was nothing they could do. I then spent time I could have been working calling other companies to try to get service, as the house was getting close to 80 degrees at 9:30 AM. A tech from Greenfox eventually arrived at around 11:15. The company never called me back at all; they didn't let me know he was coming. I received an automated text that the tech was coming 15 minutes after he arrived. He found the issue, which should have been discovered two weeks earlier at the servicing appointment. The tech then left, saying, "I'll send you the invoice." No discussion. The tech then charged us $245 for a problem that should have been caught during the initial service we already paid for. Getting an annual service from this company is useless. It appears they didn't thoroughly review for potential issues, which has left my AC not working on the hottest days of the year so far. There was no consideration on the second bill for the poor work of the technician who came out to service. They don't answer phone calls. They don't call anyone back. They don't let you know a tech is coming. Their chat responses are, at minimum, disingenuous and, at worst, outright lies. And then they still charge you double, even though it was their error. There are far better and more reliable companies in the area, with whom I will be contracting going forward.

Now we need another one done, and Jimmy, one of their techs, came out to do a fall system check and noted that our second HVAC system was getting towards the end of life and that maybe we should schedule an evaluation to assess the system further and get estimates for a new system upstairs, as the downstairs unit was replaced about 2 years ago. We called and scheduled Jimmy to come back; he did, assessed the system, and gave us some estimates and options based on the information he gathered when he initially came out. We are contemplating having them replace the system despite the cost, as Jimmy explained that the price will only go up and never go down. I'm impressed with this company and even more so knowing that it is family-owned, which is my preferred type of company. Highly recommend contacting Beltway if you have a heating or AC issue!
