"The two technicians, Brian and David, were phenomenal! They were incredibly kind, informative, and patient with me as they assessed my HVAC and vents. They explained the entire process and why what they were doing is important based on the type of system I have. As a relatively new homeowner with an old home this is very important to me. They did a thorough job of cleaning my air vents and dryer vent and I feel confident they left my home cleaner and much safer than when they arrived. I would highly recommend this company for all your HVAC needs."

"I had my HVAC replaced by Tim, Andrew and Billy. They were amazing! Courteous, friendly, kind and did a phenomenal job. I would highly recommend this crew! Thank you for taking such good care of replacing my units. You Rock! And they are very dog friendly!"

"Just wanted to acknowledge the techs, especially Matt, from Calvert Commercial HVAC, for diagnosing what the issue was with the salon HVAC unit and repairing same. The hole was caused by the wire laying on top of the copper tubing, and as you can see the wire's sheathing was missing. Hole repaired, wire repaired, salon now toasty again. It always pays to get a second opinion. Once again, thanks Matt and Rich, for a job well done."

"great service showed up when they said they would and fixed unit on a holiday"

"From soup to nuts, the entire experience was made easy for us by the company. The salesman, Nick, came out to see us the day after my system kicked the bucket, and after checking out the system, he presented me with a few different options, and without using fancy words, explained everything plainly and easy for me to understand. After I discussed things with my wife, we called him a few hours later to give the go-ahead, and he had us scheduled just 2 days out. The installation team arrived promptly at the scheduled window, and took care to treat our house like it was their own. Drop cloths were used to protect my flooring, and after the job was done they made sure to remove all the debris from the job so nothing was left. After the job was done, the job foreman took me around and showed me everything that they did and explained the function of the system, and when I had questions, they explained plainly and without complaint or exasperation. They treated me and my house with the utmost respect. I highly recommend this company for any HVAC needs anyone might have."

"In my opinion horizon did a top notch job installing my HVAC system"

"I cannot recommend this cleaning company highly enough! I hired them to do a deep clean on a three-story townhome to get it ready for the rental market, and they exceeded every expectation. Preparing a rental property is always stressful, but they made the transition seamless. Managing three floors of living space is no small feat, but the team tackled it with incredible efficiency and attention to detail. Here is what really impressed me: Flawless Attention to Detail: They didn't just do a surface wipe-down. They got into every nook and cranny, from the baseboards and window tracks to the inside of the appliances and cabinets. Tackled the High-Traffic Areas: With three floors, stairs can be a nightmare to get perfectly clean. They made the stairwells and banisters look brand new. Professional & Reliable: They arrived right on time, brought all their own high-quality supplies, and worked tirelessly until the job was done."

"Mark and helper climbed their ladder outside to the Soffit under the roof overhanging. They cleaned the vent and ran a brush all the way down to the clothes dryer. Now my clothes are dry and the amount of dust has increased due to the opened pathway. Any dust that came outside was cleaned up. Great job. Thanks!"

"Found them very thorough and professional. Did a good job and the price was reasonable. Will probably have them clean my vents yearly."

"I thought the price for water heater replacement was high. Not that I've had it done recently."
