John was particularly helpful in trouble shooting and the plan they developed was carried out quickly and professionally - and it worked.

When I asked driver to move he became defensive, beligerent and agressive in tone. Even use the F- word. I will NEVER USE BC CLOVER and DO NOT RECOMMEND this company to anyone.

Bad business practice!

Driver SAFETY. 4/24/26 License plate: 1GK1695…read more I encountered this driver today who was driving recklessly, aggressively & dangerously. I don't care how good the company is, if the driver is unsafe, they'rere not only unprofessional, they're liable to kill someone! Cars are weapons, whether they're used that way or not!!! This driver s/b fired, and the company needs to put road safety ahead of saving 3 minutes. If the driver kills someone , gets in an accident or gets ticket they'll be later than if they had been safer on the road: This driver had the audacity to nearly hit me and then honk at me. What an a***e! He's lucky I didn't call the police!

In searching for a service…read moreprovider, I was surprised that the Yelp ratings of JDL varied so much between the extremes of 5 stars and 1 star. 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.

He wouldn't even complete any maintenance in the home due to the police. The office didn't follow up on rescheduling. I'm sure they will still try to bill me. My initial concern is above. My concern now is that the owner called me at 9:41pm after I provided this review and yelled at me. I also find it interesting that Amber put this in her response and I hadn't even mentioned that part yet.

TL;DR: Avoid this company and its owner, Julian, at all costs. His professionalism ends the moment…read morehe gets paid and he tries to charge you for a work that he did not do. If I could give zero stars, I would. Julian at Nero Heating and Air Conditioning gave us one of the worst customer service experiences I've ever had. Before we signed the contract and paid for our new furnace in 2022, he was responsive, attentive, and gave every impression that he cared about earning our business. The moment the payment cleared, it felt like we no longer mattered. Messages went unanswered, conversations became cold and dismissive. 4 years later in 2026, when we called about an issue with blower he had installed, I expected at least a genuine attempt to help. Instead, he arrived with an attitude, spent very little time looking at the system, offered no meaningful diagnosis, fixed nothing, and left. We ended up hiring another HVAC company that quickly found and resolved the problem. Then came the final insult: despite providing no solution and no value, he still wanted to charge us a $75 service fee. We will never use this company again even though they are supposed to provide service under warranty for 10 years, and I would absolutely not recommend them to anyone looking for an HVAC contractor they can rely on after the check has been cashed.

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.

Can't recommend them highly enough!!!!

I called on a Sunday and talked to answering service three times and they assured someone would call. My problem simple and complex but didn't require a visit, I just needed to ask a question to rule something out but they couldn't be bothered and were quite rue about it the next day. I'm not surprised - it's sort the way of the (non) service industry today and especially in this area with its incredible wealth and overpopulated area - there's always more customers so there is not much effort to keep customers or even treat very long term customers with respect. In any case, I'm loyal but when I'm mistreated m, I'll shift my loyalty. I know D&D doesn't care. I unfortunately have a contract for another with them but I'll be calling others as my AC unit is quite and I know it needs to be replaced in next few years and I need a reliable HVAC company. If you are looking for service, I recommend looking elsewhere.
