Get matched with top heating and air conditioning pros in Prince Frederick, 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."

"ARS did a quality job installing my new HVAC system."

"I AM BUYING A HEATER SERVICE CONTRACT FROM PETRO THIS YEAR."

"My experience with Mack’s Home Services, LLC was excellent. The people are very professional and did a tremendous job. They were courteous, explained their services and pricing clearly, and things went exactly as they communicated. They were very respectful and operated very carefully throughout our home. I will use them whenever I need our HVAC systems cleaned in the future and strongly recommend them. You will not be disappointed."

"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"

"It was just an HVAC inspection, but it was a very professional and the technician was very knowledgeable and friendly. This company is awesome."

"I hired 3M after considering several other sources for furnace repair. In reviewing other proposals I found excessive charges. 3M called me and when I told him about my problem he asked if he could come and look at it. He arrived as scheduled, was professional, courteous, and thorough. After checking out the furnace he gave me an estimate that was half of my other bids. He obtained the parts, and in working on rhe system found another problem with a transformer. He obtained the part and after completing the repair said that the new parts had cost more than his estimate, but since he had missed the problem initially, he would not charge me for the extra labor. I immediately realized I was dealing with an honest person ... a rarity these days. 3M is now my permanent source for all my HVAC needs. There is no better source available than 3M."

"Removed and replaced our old HVAC systems (one for upstairs and one for downstairs). Excellent job. Highly recommended."
