"Save your money"

1.0 rating
Very Unsatisfied

When we built our new home, we had a Laars Endurance boiler installed. After 17 service calls in less than 5 years, the plumber who installed it said it must be a lemon so Laars replaced it with a new unit. We've had 7 service calls on the second unit in 5 years. The latest serviceman has tried replacing the control module and another part but has yet to get it working. He is currently checking with Tech Support.

I've owned this unit for 11 years and spent thousands of dollars to keep it going every year. I think it's time to change it out.

Furnace needs expensive repairs every year. Company doesn't return calls. What a big mistake purchasing this furnace was. Will be replacing it with anything else!

"Not sure if this helps, but"

3.0 rating

We've had our Endurance running on propane for over 10 years with no repair or maintenance cost (never serviced for anything). Main thing is we ignore some problems like the temporary ( a few seconds) hot water cut out. I grew up on electric hot water where we completely ran out if the shower was too long. I do notice that almost every time the unit sits for a long while without using heat, and then heat is called for (like in the early fall or for a late spring cold snap), it will lock out or fault, sometimes a few times. If I simply restart the one, two, or three times it seems to burn off whatever the problem is and eventually the problem goes away and it works fine again. We have an old Lennox Pulse 1 for an older portion of the house on LP that does the same thing.

"Cheap and unreliable"

1.0 rating
Very Unsatisfied

I've had two generations of Laars equipment. I bought the second because it meant I didn't have to pay for a lot of associated re-plumbing. I could just drop in the replacement unit. What a mistake. The small amount of money I saved up front meant I had to spend another decade beholden to this company's unreliable equipment. It is very hard to find people who know their gear and won't gouge you (I'm in the Boston area). Spent time directly with Laars on the phone and they were completely unhelpful.
