Get matched with top furnace / forced air heating system install or replace pros in Mount Airy, MD

"Excellent! We did a whole house remodel in 2013 and Holtzople installed the geothermal system. Our utility costs went way down compared to our previous oil furnace and electric central air conditioning system. We then signed up for their semi-annual maintenance agreement so they send a technician out every year for a tune up and cleaning before the heating season and again before the cooling season. Big shout out to Kevin, the technician who usually performs the maintenance, for his professionalism and friendliness. For 8 years now we've been enjoying care free climate control in our home at a lower price than I ever would have imagined. I highly recommend Holtzople for their products and service and Geothermal for efficiency."

"Josh did a great job assessing our older carrier heat pump. he was honest and laid out the expenses of replacing the old heat pump fan and the other parts needed."

"Mr. Dean was very professional and knowledgeable. He worked efficiently and didn't leave a speck of dirt behind. He went over the new furnace and central air system with me before leaving, making sure I was familiar with the new system operations. I recommend this owner operator company with high regards. Thank you!"

"The job went reasonably well. They completed it in a day and a half. The guys on site had a little trouble installing the high tech thermostat for the system, but their supervisor demonstrated real accountability when he showed up on a Saturday to make it right."

"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. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"From the beginning - Sean was extremely responsive to all of our questions and very flexible with scheduling the service. He installed our new humidifier on the furnace, provided instructions on how to operate it, and offered multiple tips for keeping the system running efficiently. He also offered a very fair price. He was very professional, and we would definitely hire him again!!"

"I had a high efficacy heat pump system installed by ARS 11/2 ago. I am used to gas furnace so understanding how heat pump works is an education. The mechanic was very patient in explaining how it works and what to look for if there is an issue. Of course this cold season a got an high unexpected bill from the electric company and was baffled because of the amount I spent on this high efficiency unit. They came out looked at and found no issue. They explained this was a very unusual cold season and the unit performed accordingly for sub freezing condition. They did leave a card and said if I see anytjing that look unusual please give them a call asap. The mechanic was very knowledgeable."

"My experience with him was top notch. He was accommodating to my schedule. I work nights and he was willing to come to my home in the early evening instead of normal business hours. He assured me the fix of the leak would hold until the end of summer but there was a chance that I may need a new unit next summer since the unit is over 10 years old and the leak was pretty severe. I had no other trouble with the unit the rest of the summer. His price was reasonable and he was friendly and efficienct. If I need a new unit next summer I will definitely use Tetteris Heating and Air for the replacement."

"I would hire this company again. MSR Heating and Cooling is A1 in my book."
