"Scott Lintier performed my cooling maintenance today, and like all technicians before him, he was very informative and thorough in his service. I have, and will continue to recommend Holtzople Heating, Air Conditioning & Electrical Services to everyone I come in contact with who may need the wide range of services Holtzople offers. Saying I'm very impressed is an understatement. Keep up the great work!!"

"My technician, Lily, was right on time. It was her first time to my home and she was very friendly and informative. She explained what went wrong and also showed me how to maintain some things through my routine maintenance. My service call involved a charge as it was Service, labor plus Freon to be added to my unit and the outside unit's battery. Since I have a contract with McCrea, I was not charged for the part that was to be replaced on my unit. My house is slowly cooling down as it was 90 degrees inside my home when she arrived this morning. My house lost the air conditioning on the Fourth of July and on a very hot day. I would highly recommend McCrea Heating and Air Conditioning Services of PA."

"We hired weather masters through Lowes. Adam Shapiro contacted us and assessed our needs. No drama around quote, gave us a competitive price and promised a quick install. As we were in sweltering heat with no AC , they installed a temporary window AC unit to help us tide over the next couple days, whilst we waited for the HVAC Lennox equipment. From quote to install was just within 3 days!! Everything was executed on schedule as planned and delivered as such. Shane and Steve are highly professional technicians who completed HVAC install within 8 hours. They cleaned up the area very well , tested the equipments and provided operational instructions. Highly recommend weather masters!!"

"Turned on the AC this morning to find out was blowing hot air, called up a few different companies who wanted minimum 100 bucks to come out blah blah blah, called up Markool and got connected with a technician. The technician helped me troubleshoot the issue, and have me a quick fix that will last until they make it out tomorrow to do the permanent fix. I'll be using them for all my AC needs in the future!"

"Our dryer vents from the center of the house to just under the second story eves. He did a great job of cleaning it from both ends, and adjusted the dryer hose to an optimal length and resealed it with tape. Also cleaned vents well. I am very particular about mechanics, handymen, and service people. Mack's is on the short list of people I will hire again. The serviceperson was polite and personable as well as very competent. And, he took pains not to track up the carpets. Mack's is a good choice. You'll be satisfied w the results."

We are a small family owned Heating, Ventilation, and Air Conditioning (HVAC) company located in Sharpsburg, MD. The business was started in 1989 under the name of RW Harrell's Pump Service Inc. when Diane Harrell and Ronnie Harrell purchased a well pump and water system business from a gentleman that was retiring. Ronnie had worked in the HVAC field from the time he had graduated from high school so it was natural to add HVAC to the services that this new company would offer. Ronnie and Diane built the company by word of mouth and continue to grow the company in this manner. Additional DBA - Harrell's Services. Additional fax - 928-492-8004

"The technician showed up on the assigned day and checked out our AC system for the season"

"The price was part of my check up I got. I just like that they seemed to want to talk me into having my air conditioning cleaned and it only been out there like 6 months. My interaction with them was fine. I told them no and so be it. The work turned out fine. They were fine."

"Walter aka Pete went above and beyond to fix and repair my HVAC system during this last cold weather we had. Excellent customer service"

"We needed chimney sweep & minor repairs. Scheduling was easy and the guys who showed up were on time and very professional. Work was done well and we’re very happy, will be calling them for all future work on our chimney and HVAC."
