Get matched with top central humidifier installers and replacers in Hydes, MD

"Within first month a key part failed. Blue Dot quickly responded and promised to fix the system. The replacement part arrived a fewest days later, and a 2-man crew installed it. This team needed 2 hours, but I am not complaining. The AC is back on line."

"While the technician who ultimately serviced my system was efficient and informative, the overall experience was unacceptable. It took nearly 18 hours and three separate appointments to replace a single fuse under a warranty installed on November 4, 2025. The dispatch, scheduling, and supervisory staff were dismissive and unresponsive, demonstrating a complete lack of customer care. This was, without question, the worst customer service experience I have encountered. Additionally, the failure itself appears to stem from incomplete installation guidance, as I was not properly advised on potential system vulnerabilities (such as power surges). While I appreciate the technician?s work, the breakdown in communication and service at the management level makes it difficult to recommend this company."

"We've had two HVACs and a water heater installed and I would not use them again. They offer an extended warranty that beats their competitors, but their service plans are misleading and after installing one of our A/C units and supposedly doing "maintenance" on it a year later, we learned when we went to replace a filter ourselves that they couldn't have replaced the filter at the last service because the filter cannot be replaced due to the way they installed the unit. We were told on two separate occasions that we had a service plan with them, but when they were scheduled to do our maintenance, they called to say that we didn't have a service plan, it was canceled due to non-payment (it was never communicated that our plan had lapsed during three subsequent calls). Trust the negative reviews and go with another company"

"We had a great experience! The owner was honest and forthcoming, fair on pricing, and punctual. The guys worked hard and got everything done quickly, and cleaned up after themselves. I would strongly recommend them to anyone that is looking for an HVAC contractor who knows what they are doing."

"Vernon was fantastic! He came in, inspected the work to be done, replaced our busted water heater, and was done in an hour and a half! He was very professional, courteous, and explained what he needed to do with perfection. Thanks so much for helping us out in a pinch, Vernon!"

"Robert fixed couple plumbing issues around the house in timely and professional manner.  Highly recommended!

"Five star customer service all the way. Installed a hoise humidifier and UV light into our existing system. Clean, friendly, and fair. Absolutely excellent!!"

"It turns out my central AC unit must be replaced. (I'm not surprised - it is 20 years old!) I was not prepared to set up the replacement that day, but Henry and the other tech were very professional and pleasant, and thoroughly explained the issue with my AC. They quoted a lower price to replace the whole unit than I actually expected it to be. When I'm ready to have it done, I plan to have them do the work."

"Made initial appointment 5 days in advance. On the appointment day, I phoned early afternoon to hear that my repairs had not been scheduled. Plumbers then arrived within the next hour, or so. Fixed leaking valve leading to the main line, and "snaked" bathroom sink. Took photos of tub/shower valves to order a replacement unit and gave an initial price estimate $240). After 10 days, never received a return phone call. Called office to receive a return phone calls explaining that part had not been ordered, and that there was an estimate of $625 to install a new valve unit."

"Yes Thomas did a fabulous job with the many tasks. Pressurization of the main water valve, pressurization of the hot water heater, repair of a bathroom pipe, installation of isolation valves, bath tub repair and following and checking everything was working properly. Thomas is very easy to work with. He is knowledgeable, efficient, respectful and extremely thorough."
