"Sonny came to home and explained options. Wrote up estimate same day. Installed in one full day with two techs."

"Michael arrived exactly on time and took me to sign a lease on my new apartment, stopping twice along the way so I could buy a money order for the security deposit.  He had memorized directions to the new place, which were complicated - we had no problems finding the place and he got me there right on time.  Picking out my apartment and signing the lease took much longer than expected and he waited patiently for over an hour and a half.  He then brought me home.  This was the second time I had used his service and I was just as pleased the second time as the first.  I had to reschedule twice and he was very pleasant about it - in fact he was very pleasant and professional in all our interactions. Even though it took longer than expected and even though I had to reschedule twice, he did not charge me extra.   I would highly recommend him and will use him in the future.

"I've been using ABS for 12 years on all of my cars (I tend to drive cars until they fall apart).  They've always been cheerful, reliable, and fair.  They've never tried to sell me anything that I didn't want - they call with an estimate and suggest the things that are more important to do right away and those that can be deferred, which is useful if you're on a budget.  Quality is excellent, and they try hard to fit your schedule.
One thing I find very useful is that there's a CUE bus stop across the street that goes to Vienna Metro, so I can drop my car there in the morning, take the bus to the Metro, and then pick up my car in the evening.  As long as you tell them, they'll leave the keys locked in the car, so even if you get there after they close, it works great.

"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).

"I’ve used Drymount Air multiple times for multiple projects. They installed a new water heater, added a humidifier, disconnected and reconnected my air conditioners during a patio installation, put in new smart thermostats and various plumbing jobs. They have always been upfront and honest about what I should and shouldn’t do and given me multiple options. When is used to get multiple estimates, they were typically the lowest, I now don’t even get other estimates. They have always arrived on time, sometimes early squeezing me in during a lunch or between customers. They are courteous and during the pandemic have taken all safety precautions. And lastly came late in an evening to help with an emergency and did what was necessary to get me through the night and came back the next day to finish. They are the first call I would make if I needed anything and would be lost if they were unavailable. I highly recommend!"
