"I couldn't be happier with the service I received from McCrea Heating and Air Conditioning Services of Maryland. Upon returning from vacation on a 100 degree July day, I found my old HVAC system basically dead (90 degrees in my kitchen!) ... Shane immediately came out to provide an estimate, we signed a contract on the spot, and he kindly provided some freon to hold me over until the new system could be installed. Brian and Nick showed up exactly on time to install the unit, used drop cloths to protect my flooring, and were exceedingly polite and professional throughout. I'd highly recommend this organization."

"I would highly recommend HPC Services! They responded quickly when we called for an estimate on a new heat pump. The gentlemen who were in our home installing the unit were professional and polite and very nice to our little dogs. Sergio stayed and answered all of our questions until late in the evening. They offered us a free duct cleaning and that was completed on Monday after the Friday install. Emmett worked quickly and professionally. He was so very nice and easy to talk to. I was most impressed with the fact that they offer a Veterans discount. If are looking for an amazing company for any HVAC work, I urge you to give them a call!! Karen Hamner"
