Burnham Freedom Boiler Reviews

"Terrible company & unit"

1.0 rating
Very Unsatisfied

Nothing but problems. We own 2 of these in our multi and it is always something! Useless customer service Avoid Burnham!

Very Unsatisfied

I'm very unhappy with this unit. In the first year (2011), I replaced the pressure switch twice and installed a new transformer and thermostat. To date (2014) I have had 13 service calls for no heat, replaced the pressure switch again and the flue sensor. Not a happy customer and would never recommend this unit to anyone!

"Fan Failed After 2 Years With NO Warranty!!!"

1.0 rating
Very Unsatisfied

I own an HVAC company and have over 30 years in the business. We installed a Freedom condensing gas boiler 2 years ago for a customer. The boiler keeps tripping out with an error code that says the fan is not running. Burnham tech says the fan has a computer in it that fails, even though the fan is still good. He knew what the problem was right away, so they are having this problem in more than one unit. My cost on the fan is $441!!! If I put a little markup on it and charge labor, the customer will be out $1000. So, I'm going to install it free and sell it at my cost. AVOID BURNHAM PRODUCTS AT ALL COST.

"Horrible Horrible Horrible"

1.0 rating
Very Unsatisfied

This Burnham boiler has turned out to be extremely temperamental and unreliable. The control unit had to be replaced after 2 years at a cost of $775.00. The Burnham company itself seems to employ only rude and ignorant people who know nothing about the product they sell. A technician got an answer "we don't know what's wrong, you'll have to disassemble the entire unit".

"Freedom Gas Boiler"

1.0 rating
Very Unsatisfied

Installed August 2010. Used for heating and hot water. Problems began after 1 year with error codes. Installer/maintenance company does not have a clue. Factory non-responsive. Parts unavailable. Down for over a week in winter. Have no confidence in product or support. Sum it up: pos.

Other Freedom Reviews

Most commenters on HVAC forums seem to regard the Freedom as a good boiler, though given a choice on heatinghelp.com between the Freedom and a comparable Triangle Tube model, most people chose the Triangle Tube. Among the problems with the Freedom discussed on hvac-talk.com are a noisy exhaust and blower failure, with most professionals stating that these problems are usually related to the installation and not the unit itself.

Freedom Warranty

The Burnham Freedom boiler is covered by a 15-year limited heat exchanger warranty and a 1-year parts warranty. The last 5 years of the 15-year heat exchanger warranty are prorated. Labor costs are not covered under the warranty.
