Holtzople Heating, Air Conditioning, & Electrical Services
Holtzople is a leading HVAC company in Frederick, Carroll, and Washington counties in Maryland, as well as Adams and small parts of Franklin & York counties in Pennsylvania, featuring all the top brands in the Heating and Cooling industry, such as Trane, Bryant, Lennox, Carrier, ClimateMaster, WaterFurnace, and more. We recently added an electrical department to our services, making us your one-stop shop for HVAC and electrical needs. Quality is Not Expensive, It's Priceless!
"Holtzople installed a geothermal system in 2013 to replace our heating oil furnace and electric air conditioning unit. Boy did that cut our heating and cooling bill way down! This review is about the recent semi-annual service maintenance visit. Shout out to Kevin the technician who is friendly, professional and focused. He gets right down to business and is quiet as a mouse as he thoroughly goes through the extensive maintenance checklist and performs all required tasks. He then takes the time to fully brief us on what he did what he found and what if anything he recommends. He then opens it up for questions and is very patient and thorough in answereing any questions we might have. Hint: he's also an expert on anything Disney World if you might be thinking about visiting there.... We highly recommend Holtzople, a great company, because they really do take care of us."
