Get matched with top central a/c installers in Cascade, MD

"The whole house could hear the vibration when our two year old Tran xv20i heat pump was at 67% work load. It seems the issue started from day one it was installed. Tried to reach out the installer but they went under. In June, I called McCrea. Mark Dzbynski came over, carefully checked everything and then concluded that refrigerant was not charged to the correct capacity. He explained that our system line is longer than usually and additional refrigerant is needed to compensate the length. He carefully calculated and addded the correct amount based on the temperate & length. From June and Oct, the vigration never came back. No one can tell when the system is on because it works so quietly. I really appraicate the work done by Mark and his work ethinics. Very pleased!"

"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."

"Very nice company Respectful of property Did a very nice job installing my heat pump, worked with me on price, and they were very careful when installing the equipment so as not to damage my property like it was their own house !"

"They came and inspected the sump pump. They recommended for it to be replaced. I was okay with it so they replaced it. They completed within half an hour. We then discussed the bill. They agreed to take off $50 because they have an Angie's List coupon that offers $50 off. There was also a coupon for $250 off a system installation for Angie's List members. I told them of this and they said it would only apply for HVAC units and I said to them that they are more than HVAC company, they provide more services than HVAC. They did not specify that its only for HVAC. The technician agreed and said that they're going to have to change that within our website. This was extremely misleading and felt like a bait and switch."

"We received 3 quotes and Wenbrooke was the best value. They got us scheduled quickly. The team arrived early in the morning and were very professional and well versed in the installation."

"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!"

"They put in a new system. They had to take everything existing out. They showed up when they were supposed to and finished in a week. They were clean and efficient. It was not an easy task. They cleaned up after themselves. Very professional. The owner explained everything to us."
