"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."

"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"

"Excellent company! My water heater stopped working on New Years Eve. Unfortunately, the water heater is behind my HVAC, so they had to remove the HVAC, remove the old water heater, install the new heater, and replace the HVAC. They did a perfect job. They also replaced the freon in my HVAC, because the prior repairmen didn’t add freon. In addition, they fixed the jets in my spa. The team arrived on time, displayed professionalism, and cleaned up afterwards. I would definitely hire them again."

"Great job by Jiffy. They had to pull a new water line under my townhouse slab foundation to replace the leaking poly water line. Pete Kristiansen, who is very knowledgeable and experienced, knew exactly what needed to be done. Plus it was a fair price. Highly recommend them."

"Although the installation took more than a day, the communication of the installer was excellent. The job required new pipes and an expansion tank, so it was more than installing one piece of equipment. All questions were answered (there were many) and the workmanship met my high standards."

"Professional,
Knowledgeable, Integrity, Reasonable Price, Quick Response, these are some of the characteristics that I would use to describe Kurt Randell and AHS.  We have used several mold remediation services and Air Quality Checks in the past at various properties with mixed results.  Based on reviews and my external validations of Kurt?s certifications we used AHS.  Simply put, we were Very Happy.  Kurt was easy to schedule, prompt to arrive, and leveraged several electronic tools, including infrared, moisture meter, and an air sampling to determine if we had an issue. Our experience with AHS was identical if not better then the others on Angies List.  Our primary goal was to determine allergens in the air as one family member was experiencing heightened allergies in the basement.  We had 5 air samples taken through out the house and no issues were identified.  Kurt also checked for excessive moisture/ water in the basement to determine if we had a leak or water seeping in through the basement.  After one of the bigger June 2013 storms experienced in Metro DC (yes those), Kurt came back after the initial work was completed to determine if we had a basement issue.  Kurt found slightly elevated moisture levels in one 3' X 4' section of the basement, but not enough to warrant remediation.  Instead we placed this on the watch list.  Kurt could have easily attempted to make this into an issuing requiring remediation and bigger dollars, but he did not.  That shows integrity and commitment to his work. We would not hesitate to use Kurt/ AHS again. "

"My well pump pressure tank needed service and I called Friday and Barbara was very professional and eager to help. She took the time to understand the issue and even reviewed the pictures. Barbara is very passionate about her job. She was able to schedule for Saturday. Dave came out. He called to let me know that he was on his way and let me know when he will arrive. He was very punctual, professional, friendly, and down to business. Totally impressed with the way he solved the problem and made sure that answered all of my questions. This company is very ethical and I would recommend them to anyone."
