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

"Everyone from Presidential has been friendly and helpful -- great customer service! Glenn came to our home to discuss options to replace our furnace (fuel oil) and AC systems with a heat pump. He immediately understood that we were looking for a heat pump eligible for the new tax credits (unlike another company, who only provided estimates on what they had in stock). He prepared the estimates for 3 different models on site, and he noted that the heat pump eligible for the tax credit would cost about the same as an older model (unlike what the first company told us). We were able to schedule installation quickly, and then the adventures began. Harvey and Andre were here for 12+ hours...because a wire was either never connected at the factory or came loose during shipping. We also had to replace a defective line from our house to the unit. While it was a complicated install (not the fault of Presidential), we rec'd great service from hardworking staff members. Highly recommend!"

"I was looking for a new Heat/AC business for maintenance after many less than excellent experiences in the past. Several people recommended Holtzpole, so I decided to give them a try. I am glad I did because they are the best. I was specifically looking for a yearly maintenance contract and also someone I could rely on in an emergency. Before they would consider their top tier maintenance contract, a technician had to come and inspect the system. I was given a 3-hour window for the appointment and Kevin arrived within the first hour. I ask for no shoes in the house and Kevin took care to put on and remove shoe covers every time he came in or left the house. Kevin performed the check and explained the adjustments he made. I also pointed out a concern regarding a leaking drainage tube and Kevin was able to replace this at a fair price. I’m so glad I found Holtzpole and I will definitely be recommending them to others."

"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"One of the best contractor experiences we have ever had. Jim called the day before to confirm the appointment. Larry the Plumber was so nice to deal with. He put on she covers to protect my wood floors, worked very neatly and gave us some tips about ongoing maintenance. He did a perfect job. This review us for Petro in central NJ. i was not able to change the company location. We hired them through Amazon."
