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!"

"The replacement of my a/c ( with indoor coil) and furnace was handled in an extremely professional way. Holtzople Heating and AC helped me to find the best replacement units for my 20 year old Trane system. I am impressed with the knowledge of the sales person sent to provide quotes. I am also impressed by the skill and meticulous care that the installers took while replacing my entire heating and cooling system. Within a day, they took out my old system, installed the new system up to factory specs, tested and made sure all phases of heating and cooling were functioning as they should, and cleaned up, taking away all of the old unit, leaving nothing behind. The last thing the head installer told me was that a quality control team would be in touch and be coming in within the next two weeks to make sure everything was continuing to operate as it should. This attention to detail, and customer satisfaction is what has impressed me the most about Holtzople Hearing and A/C."

"Called another company I was familiar with but had to pursue them for 5 days! No heat and told it was best to replace the entire unit by 3rd day and they'd order the parts (3 men, 4 hours, & $3k was what I was told). Finally, decided it was too much suffering and temps were dropping. Called Relax Air and he came within the hour, did a thorough analysis. Very professional. The final outcome was one of 3 parts were broken. Also a parts dealer, returned with the parts and tried each one. It was the module, fixed in one day, and for under $1k. He also checked/fixed the humidifier (which said initial company said they did upon initial repair visit and 2 yrs ago for regular maintenance) and adjusted the heating so the house is now perfectly balanced. After 4 years living here, finally no more cold spots!"

"Blake M. was able to work thru issues created by installation in a double wide vs. a stick built house. Service was professional and pleasant. Blake kept me informed every step of the way toward project completion. Area was left spotless."

"JDL replaced a defective propane furnace and did an excellent job. The new one is installed better than the original. JDL scheduled an inspection by the county inspector also said they did an excellent job. They were efficient, timely and friendly."

"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."

"Requested quotes due to a burning small coming from my HVAC unit. Pro who came to my home for the initial quote was amazing. He answered all my questions and explained the urgency of getting my unite replaced. He provided options for an upgraded unit and financing. Not only that, I was able to get a next day appointment for installation which was super helpful because it is been getting really cold overnight. I'd highly suggest hiring ARS of Maryland."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable.
