Get matched with top heating and air conditioning pros in Callaway, MD

"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."

"Great! He provided additional information, suggesting I install a UV Light Air Purifier to my HVAC system. Which would help eliminate the possibility of mold growing in my vents."

"Mack is dedicated to what he does and went out of his way to diagnose my problem and link me with HVAC personnel who could address related issues. He cleaned my ducts perfectly and my system is working well now."

"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"

"We hired them to do the spring servicing of our HVAC and liked the responsiveness of their customer service, so we hired them to use their plumbing services. They replaced our water heater, 2 toilets and installed a water filtering system. They are now our go-to for HVAC or plumbing needs."

"Outstanding! Had multiple issues with an aged HVAC system. We didn't have cooling or heating. HPC Services responded promptly, diagnosed the problems and expertly repaired the issues while explaining exactly what happened and how to maintain the system moving forward. Great coordination and teamwork from their entire team. We would not hesitate to use this company again!"

"It was pricy, but it was good service. Well, that's hard to say because it's all expensive, as oppose to any other air conditioning company, it's about the same, just too much money in general."
