"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!"

"Travis Grove contacted me less than a minute after I submitted a request. He came day-of on a Friday afternoon to inspect, and quickly found the capacitor had failed. He had a replacement on hand, though the issue was the fan as well. Travis made sure to keep me informed of parts availability (fan vendor closed on weekends), and text me updates. If his arrival time changed, he made sure to let me know. The new fan is more powerful, to provide better cooling. He noticed my refrigerant pressure was low as well, and made sure to fill it up. Travis was friendly and easy to talk to. His price was very reasonable, including all parts and multiple hours of labor over two days. My system is working well and cooling better than before. All set for the summer heat!"

"I brought my car in for service because it was running rough. A few months before I had the power steering pump replaced and within about a month it began to make a noise. I figured it was due to low fluid but, the fluid level was fine. ABS told me they would diagnose my car and give me a call and tell me what I needed to repair. They called me about an hour later at work and listed the repairs they recommended. Their list included a new power steering pump. I told them to not replace the pump, but to do all of the other repairs. I picked my car up that evening and as I was driving away noticed that the power steering pump wasn't making any noise. They didn't charge me for a new pump. So, when got home, I looked under the hood to make sure they hadn't replace the pump - they didn't. It's been about six months and my car is still running well and the power steering pump isn't making any noise. They did something to the power steering pump - repaired it, without charging me. I am thankful that I found ABS - They are polite, professional and highly competent!

"The driver arrived in a large SUV (though we had discussed a sedan) because he thought we would be more comfortable in a larger car. He was polite and professional and helpful. The ride was nice and quick - and we arrived at Dulles without any problems.
I will definitely use the service again and would recommend to others.

"Continental's technicians were highly experienced, professional, considerate, respectful, hard working, and neat. They arrived on-time when scheduled. Allied's drilling and trenching crews were excellent also. This was a big messy job that took about a week and we are very happy with the work that they did. The owner of Continental, Frank Jackson, sold us the system. He provided an extensive reference list that went back at least 15 years. He was on-site for most of the job providing hands-on supervision of his technicians. His technicians are so experienced that he didn't have to be there to supervise them. Rather, I believe he was there to make sure that the job was finished on time because they are so busy. Allied had an on-site supervisor at the start of the drilling process to finalize the location of the loop bores, but their drilling crew was highly experienced and needed no supervision.
Installing geothermal is a messy job. The vertical bores and horizontal trenching for the ground loop makes a muddy mess. The drillers from Allied were very respectful to the property, much more than I expected. I expected that the drilling process would make "a mess and a half" but it only made a mess! At the end of the job the ground was re-leveled and ready for seed, which has already popped and growing grass. As one of the drillers said "the mess only takes grass seed to fix".
The HVAC technicians from Continental left the spaces where they worked in "broom-clean" condition. We had to do some "deep cleaning" afterwards, but this was completely reasonable.
We expressed our concerns about the job to the technicians before they started work because we do not know much about HVAC or geothermal. They took the time to explain what they were going to do and how they were going to do it. They kept us fully informed about their progress and included us in the decision making process when they had more than one way of running a pipe or duct. They made us feel really comfortable and that we were getting a top-notch job.
While the cost for the system from Continental was a little bit higher than their competitors I think we got value for money. In addition to the reference list we received during the sale process, we also know two families that used Continental in the recent past and they are very happy with the work that was performed.
We would use Continental again and would recommend them to others.
If you go with the option to integrate your hot water heater with the geothermal system (which is supposed to reduce the cost of the hot water that you use) I would reccommend that you bite the bullet and have a preheat tank installed at additional cost. We didn't do that and in retrospect we should have based on some further reading that we did about how to get the most bang for the buck from geothermal. It would be easy to install the preheat tank during a new construction project. It would be harder to install the preheat tank during a replacement project (like ours was).

"Our sump pump stopped working unexpectedly on Saturday, February 10 so I called Jerry's knowing they have 24 hour emergency service and our first experience with Jerry's was very positive. Due to the fact that it was raining all day and would be into the weekend, there was no time to contact my home warranty company. When I called (late Saturday afternoon), Jerry answered the phone and had his on-call technician get in touch with me immediately. Steve, the on-call technician, arrived within the hour. He assessed the situation and confirmed that our sump pump had to be replaced. Steve was polite, thorough and professional. He cleaned the interior of our sump pump and installed a new product that was clearly much higher quality than the previous one. So, all in all a second very positive experience which prevented our basement from flooding. Thank you Jerry's. We'll be back."

"Excellent service. Our first move from Hanover to Severn ended up being on the rainiest day on record. Guys came out, moved everything that could be moved with out water damage. They were fast, and there was no damage even under horrible conditions, and a 2 difficult angled landings between floors. On our second move, they hustled to get everything packed and loaded on the first day. When we met them in NC, they got everything unpacked and moved into place with speed and no damage to any furniture. Some of the items we had include two very heavy recliner couches, and 4 bedrooms worth of stuff.
