Business ProfileforARC Mechanical Contractors, Inc.

From the beginning there were issues with our heating system installation. First, ARC did not schedule an electrician so the installation was not completed for several weeks after the agreed upon completion date in our contract. Second, the electricians ARC subcontracted to complete the work violated three electrical code requirements in ** and created a fire hazard in our ********* dragged their feet for well over a year getting someone out to fix the safety issues. I persisted and eventually resolved the problems with a different contractor. Third, there have been consistent issues with the system keeping the house warm. When temperatures drop below 40F the house starts getting cold and continues to fare worse and worse as temperatures drop lower. In the winter of 2023 we had burst pipes and flooding because the system could not keep the house above freezing temperatures. The equipment installed is rated to work at 100% capacity down to 5F and at a reduced capacity down to -13F.I have contacted the manufacturer ************ who has confirmed that ARC did not properly design the system for our heating needs and did not perform the necessary engineering calculations required to have a functional system (in regards to assessing heating needs of the building and selecting proper equipment under ACCA trade association guidelines).The contractor has stated they do not follow the engineering guidelines of the systems they install and instead perform installations using "rule of thumb". I requested an engineering calculation be done retroactively to prove that the installed system was suited to our ********* generated a fraudulent engineering report with values manipulated to reflect the performance of the equipment they installed. The values entered into the engineering software do not match the home. This practice is unethical, ignores installation guidelines for equipment, and doesn't meet standards followed by HVAC trade. It may also invalidate equipment warranty.
