Could you also refer me to someone in the Alamogordo, NM area that installs and repairs your product. My address is 27 pueblo trail, alamogordo, NM 88310. tel # 702 306 4065. thank you in advanced.

I had the Laars Mini Therm JVS100 installed just after Hurricane Sandy and so far I’ve had 3 service calls. One for the expansion tank that went bad after 1 year. 2- Had to replace 2 stage gas valve (cost $500 parts and labor)3-Leaking relief valve twice. So far this unit has cost me over $1000 in repairs and it’s only 3 years old. Will never buy another Laars product again!
You are so interesting! I don’t suppose I’ve truly
read anything like that before. So wonderful to discover someone
with genuine thoughts on this issue. Seriously.. many thanks for starting this up.
This website is something that is required on the web, someone with some originality!
I purchased a Laars JVS 125 from a supplier in the metro Washington DC. Area last October 2021 and installed it that same month. Upon the homeowner firing it off this fall,2022, it started having intermittent flame failures. The only way to get the boiler back on was to cycle power to the boiler and the gas valve. The pilot assembly would light but the gas valve would not open. I replaced the gas valve and pilot assembly and the problem stopped. I turned in the old parts for warranty and was denied the claim. The boiler was not quite one month over a year from the install date. Come to find out the boiler was manufactured in 2019. Sat in a warehouse somewhere until I purchased it in October of 2021. The initial response from the factory was just that it was a 3 year old boiler. Until I told the local supplier to check their records on the sale. The local supplier then went back to the factory on the warranty parts which was again denied. One month out of warranty from the date of sale and install 10/30/21. Just a heads up if you are thinking of purchasing a LAARS boiler in the future.
