Saturday night call for gas leak at home. Technician arrived quickly, repaired the leak, and was friendly and knowledgeable. Also advised me on how to repair a broken circulator pump. Very professional.
Thinking of having AGS do work in your home? Let me review the plumbing/HVAC work they did in our new house in 2005: 1. They installed two older Lennox A/C systems that used R-22, knowing it would be banned within the next few years. The Lennox rep thought they were older systems they had lying around their warehouse. Owner Ken Jaeger told me not to worry, people in NH don't use A/C very often anyway; 2. They installed a small, inferior well tank and incorrect well pump that needed to be replaced; 3. They installed a Rinnai tankless water heater that was replaced this month that the installer said was older than the time it was originally installed, another warehouse lay-around; 4. They placed the Rinnai at the furthest point away from where the water was needed. Nothing like waiting 10 minutes to take a shower; 5. They incorrectly installed outdoor sillcocks, one which was angled into the basement that later froze and burst, another where they compromised the integrity of a parallam by notching it; 6. They placed the boiler on wood rather than a raised concrete or block pad; 7. They vented the boiler exhaust and intake so close to each other that the PVC pipe started to melt. The foam they used also started to burn. Three contractors told us we were very lucky a major fire didn't break out in the cavity. All this was done to maximize their profit margin and/or because they didn't know what they were doing.You had better watch them closely, ask lots of questions, and check out the equipment they sell you - that's if you want to take a chance.
My wife & I want to extend our sincere appreciation for the exemplary work done by Craig & Ben during installation of our replacement gas boiler (Weil McLain GV90+4). Their attention to detail in installation, helpful manner and willingness to work far beyond what was probably anticipated, with no comment or complaint (to us) was amazing. They both represent the best in your business - professional services. You can be assured, given the question or opportunity, we won't hesitate to recommend AGS Services. Bruce & Judy Healey, Newbury, NH
I had a lot of unanswered questions about the different options from another local company. Ken made all crystal clear and set us up with a great dual speed American Standard furnace. Will surely go back for more expert help. 👍
I had my failing hot water tank replaced by an On demand water heater by Rinnai. AGS was responsive to my needs, came and gave me a quote and quickly did the job. Jason M. did a high quality awesome job I highly recommend AGS Andre C. Thanks
We own a cabin in Antrim. AGS has been instrumental in keeping that cabin working. They have helped in is many way related to seasonal opening and closing, offered great advice, and helped us with systems aside from HVAC. The office answers the phone (a miracle today), and the Techs, usually Jason, are all highly skilled, and very upbeat. When I told Jason about a looming issue by cell phone, he said, "I'm on my way and I'm gonna make it work. Don't worry." Over many visits AGS has ALWAYS been on time, and the tech calls when he is on the way. Without exception, the price is always fair and well worth every penny.
