Additional Notes

Complaint: $4,500 was paid for a diagnosis and boiler repair. The boiler was not successfully repaired. Upon inspection from another licensed technician, the work by Carlson was not performed to building code. Carlson refuses to provide reimbursement even though they have acknowledged that the work was not done correctly. Other contractors have recommended complete replacement of the unit.

Desired Settlement: Complete Refund

Business Response: Carlson Mechanical has tried to resolve this issue with the customer Mr. ****. When Carlson Mechanical was asked to do the repairs to this boiler, it was just prior to Mr. **** purchasing the home in December
2014. Through the real estate agent and the escrow company, Carlson Mechanical
was asked to repair the boiler so that it was fully functional. In order to do
that, a few new components had to be installed to get the boiler firing. 
All of the equipment was installed correctly. The boiler was fully functional
and heating after our repairs were complete. The real estate agent, and the
escrow company who paid for the repairs ($3832.50 paid by the escrow company,
and $227.76 paid by the real estate agent), acknowledged that the boiler was
successfully repaired and functioning or they would not have been able to go to
settlement with the customer. During the repair our mechanic noticed that the
boiler pump was noisy and should be replaced. Mr. **** agreed and paid for the
new pump ($498.23).

On two other occasions after Mr. **** moved into the home, we were called by
Mr. **** to come out for new issues with the boiler, though it was still firing
and heating both times. We did not charge Mr. **** for these service calls. It
was on one of these subsequent service calls that our mechanic noticed that a
pre-existing valve needed to be re-located.  We have offered several times
to move the valve, installed by others, to ensure that the new safety controls
we installed would be up to code. We have offered to do this at no charge to
the customer. This may be what Mr. **** is referring to when he says:
".... they have acknowledged that the work was not done
correctly."  We reported to Mr. **** that the valve was not in the
correct place, and offered to move it for him. We have never acknowledged to
Mr. **** that the work we performed was done incorrectly.


The last time we went out to his home, on February 11th, 2015, it was to
check out some noises and a white substance leaking from the boiler. Our
experienced mechanic had never seen a substance like that and concluded the
possibility of an internal leak in the boiler might be the cause. The boiler
was still fully functional and heating at that time. No actual leaks were
visible and the boiler appeared to be holding pressure. After that we gave Mr.
**** a proposal to replace the boiler, and we did so at a very generous
discount, offering to credit him for the work we had already done towards the
purchase price.  Mr. **** has declined that offer.


Since then we have received many notices that Mr. ****
has been publicly misrepresenting the work performed by Carlson Mechanical. We
have always taken great pride in our customer service and stand behind the work
that we do with a full one year warranty. Our customers' satisfaction is always
our first priority of business.

In summary, all new components supplied by Carlson Mechanical for Mr. ****'s
boiler were installed properly and worked as intended. The boiler was fully
functional after the work was completed. Carlson Mechanical stands behind its
one year warranty on the parts and labor that we supplied. The fact that the
boiler later developed additional issues, which were not related to our work,
is beyond our scope of responsibility. Carlson Mechanical states in all of its
proposals that “any existing part of a heating system can fail or become
damaged when subjected to the normal stress of being worked on. While we will
use all due diligence and care when working with existing parts, Carlson
Mechanical is not responsible for the replacement or repair of any existing
part, component, radiator, pipe, etc. that breaks or fails while being worked


Carlson Mechanical has been in business for almost
twenty years. Our skilled mechanics have almost ninety years experience among
them. We take great pride in the work that we do and we always strive to exceed
our customer's expectations. Our efforts to resolve this with Mr. **** have
been sincere and with the high standard of integrity that we practice at
Carlson Mechanical.
