I had a 4 1/2‑year‑old Carrier heat pump that needed repair. This company charged nearly $1,300 in…read morediagnostic and labor fees yet never identified the problem. The process dragged on for over four months, mostly waiting for parts, and I ended up exactly where I started. Every replacement part they installed failed, and the troubleshooting went in circles with no progress. The technician genuinely tried, but nothing was resolved. On the last visit, they installed another board with no improvement, then attempted to charge me again. I refused -- nothing had been diagnosed or fixed, and I was already out $1,300. After that, the company stopped responding to calls and emails. Only when I reported the issue to the manufacturer did the owner contact me, demanding $369 for the previous visit and full payment upfront for any future service. When I pushed back, he emailed saying the company was "parting ways" with me. In short, the company demonstrated poor customer service, charged repeatedly without delivering a solution, and stopped communicating when they couldn't figure out the issue. I ultimately purchased a brand‑new HVAC system because I no longer felt safe relying on the original equipment after months of failed repairs.

***AVOID AT ALL COSTS***…read more We contacted K&B as an extension of our home warranty plan (American Home Shield-- whole other issue but TLDR; stay away from them too) due to an issue with our HVAC systems. The technician who came out was prompt and professional; however the follow-up after was nothing short of a nightmare. We were told a part needed to be ordered to correct the issue and trying to contact this company in any shape/form/fashion was not only unequivocal but a circuitous process between the home warranty company and K&B directly (who we were instructed to follow up with from home warranty). We called the number listed on the website only to receive the message that the mailbox was full. We were redirected to a dispatcher who only offered the explanation for no repeated calls back after 2-3 days that she was "only the dispatcher." After one week of no AC in 90+ degree weather, I went through the home warranty system yet AGAIN to schedule a follow-up. The day of, I received a call from the same technician to be told that he wasn't even certain the part had been ordered and had no idea why the follow-up was scheduled. I texted the number the dispatcher provided (and yes, she said to text if he did not answer) multiple times in very polite manners pleading for communication and received absolutely NOTHING. This company is not only unreliable but unprofessional to the point of being nothing short of Casper the (unfriendly) ghost--basically no way to effectively communicate, and they were unbothered by any urgency in the matter despite it being the dead of heat in the middle of August. Do not use-- I repeat: DO NOT EVEN GIVE THEM THE PLEASURE OF SUBTRACTING MINUTES FROM THEIR BOOST MOBILE PHONE PLAN!!!

I was on my way to work when I saw two of your trucks (love the graphics). I didn't have time to speak with the two technicians, so I noted the phone number to research later. After reading the reviews, I placed an online request for service. I was contacted within the hour (on a Saturday!) by Billy (weekend tech) who told me he could come that day if it was urgent (it wasn't). He forwarded my request to Lindsay, who contacted me the following Monday. She explained pricing options and scheduled service for the following day. The service tech (Bill) was great! He arrived on time, assessed the issue, and completed the repair. He answered all of my questions (even the dumb ones)! I could tell he enjoys the job and takes pride in his work. To say I am impressed with this company is an understatement. From start to finish, this was a stress-free ordeal. I am now a proud member of the Comfort Club and highly recommend Maryland Heating and Air!
