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

"I shopped around and received quotes from this company and 3 others for installation of a new HVAC for my condo. Horizon had a fair price and the customer service and installation was worth it. The technicians and consultants were all professional and got the job done in a timely manner. Would hire again and highly recommend to others. Thank you Shawn, Michael, James, and Butch!"

"The installation crew left work area clean. Installation was very nice"

"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."

"First, my project was to install, from scratch, a new HVAC system, including ducting, with tha furnace in basement (initially, it was upstears in a closed). Last year and early this year, I got 3 contractors on site, by direct call, and none of them answered my spefic questions but taking pictures and promising that will send an estimate. I never got it. I was getting anxious. So I got the idea go to Angi. First visit I got in the same day I put my request on Angie's site, called his boss advice me to just change the furnace. I could not, because the previous system was heating OK only one half of the house. Finally, next day I got AJB visit an made me happy. He understood perfectly what I wanted and my concerns and explained to better and quite ingenious solutions on my suggestions. I understood him perfectly because I have strong knowledge of aero-dinamicsor or fluid mechanics so I signed the contract right then. Now, I have a sweet warm house in every corner of it."

"We needed quick service due to the heavy rain water damage we sustained due to non-functioning sump pump. Vernon was very responsive and was on-site that day and was able to replace our sump pump with a new unit He then returned and installed a back-up system and fixed some piping on the outside of the house. Great service and a pleasure to deal with."

My 1952 house was not equipped with a vent, nor proper traps for either the washing machine or sink. There were sewer gases backing up on occasion, into the sink area, which is of course unpleasant.

Robert installed the traps, then came back to add the vent to the outside of the house. He did not have to go through the attic and roof. The end result looks like it was built with the house, and blends in well with the exterior.

He responds to my need for help either instantly or within 24 hours, is professional and knows his business. Anyone he hires is up to his standards, and those are very high. Having a reliable and qualified plumber is key to survival, and for that need, I go to Robert!!

"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."

"Earl arrived on time and installed a customer-supplied disposal carefully, professionally, and in timely fashion. With the $15 Angie's List coupon, the entire job was $145, a very fair and reasonable price. Will definitely be using him again to replace a whole-house water filter, and will recommend him highly."
