"The technician (Dennis) was very knowledgeable and professional. 2 zone service performed and took time to answer all my questions. I plan to continue to use McCrea for all my heating and air conditioning services/repairs/replacements."

"Although the AC unit was working, it was leaking water. I had another company come in and tell me that the main drain pan was cracked and that it would cost $2880 to repair or I could buy a new unit costing over $8500 dollars. I called Relax Air for a second opinion. Kamal and his crew came out the next day and confirmed that the drain pan was cracked and leaking. His repair cost? $400. I also had him do two other HVAC related jobs while he was there (replacing AC disconnect box and installing a water float switch]. They had everything done in and hour and a half. Total cost: $675. Kamal is fast, efficient and most of all honest. I would recommend him to anyone."

"Eon, the services technician, took time going over each system and explaining the condition and repairs need. He was great!"

"After noticing my furnace was offline and was showing an error message, I called to request a service call. They were able to fit me in same day, diagnose the issue, identify potential future concerns to monitor and repair the issue on the spot. My technician was professional, explained the options clearly and ensured that all equipment was operational before he completed the job. Everything went smoothly, and while an unexpected problem with a major home system is never a good surprise, I was very pleased with the speedy resolution."

"Extremely professional. They showed up on time, repair/replace completed within their time estimate, comprehensive service provided. "They did exactly what they said they were going to do exactly how they said it would be done." Best repair interaction I've had in years!"

"<p>Best HVAC company ever!  </p> <p>They went above and beyond to fix repairs right away.  Came out rather quickly and stayed as long as it took to figure out the problem.  Their customer service is all around excellent!  I originally called at 4:00 am in the morning and got an actual human voice who respectfully listened to me and was ready to help.  Promises were always kept on calling me back and calling to let me know the tech was on his way including an email was sent as well!  The tech's are extremely knowledgeable/experienced!  Pride is taken in their work in making sure the problem is fixed RIGHT, not just assuming.  They are all very pleasant to deal with in every aspect.  I highly recommend them and will never call another HVAC company again.</p> <br />"

"Great service. The technician was very professional."

"Thank you Fauquier Mechanical (Derek Goff and staff) for the excellent work done installing our new central air conditioning system. We highly recommend this company. Their knowledge, thoroughness, punctuality and overall professionalism gave us peace of mind. The quote they gave was the price we paid-no hidden costs- no high pressure sales. We highly recommend this company."

"Being a MVP customer was time for Heating/Cooling safety inspections. Kevin Stanley was the HVAC Service Tech assigned to the job. He went over a few issues on our older unit he found during his inspection. I never felt pressured to have the work done and so glad he resolved them on the same day. He definitely went out of his way doing a great job. He explained everything to me that he was doing and also answering all the questions I had. The price was reasonable. Will definitely call Appleton Campbell when needing home repairs, this is our 3rd project they’ve taken care of. Thanks again"
