    Summit Mechanical response to review by Jim from 3/10/15

    by Ryan Brobin , 11/25/2015

    We are sorry to hear that you were unsatisfied with the work performed. It is unfortunate you did not contact us back as we are unable to fix any mistakes or further issues if we are not made aware of them.Had you called us back, we would have sent the technician back out to determine if the previous work was misdiagnosed and also to determine if further work would have also been necessary. Had we found we had been mistaken in our diagnose, we could have given options such as refunding the previous work or performing the rest of the necessary work mentioned under Summit Warranty. Had you called us back you may have saved most or all of that additional $750 if it was in fact the way the 2nd company said.In all human service industries, mistakes can and will happen, and sometimes new parts will be faulty. We have no way of knowing if we made a mistake or if there were just further repairs that were also necessary. Either way, when mistakes happen, you'll want the company that will come back out until they've made it right and made sure you were taken care of. That is Summit Mechanical.

    After expensive and unnecessary repairs another contractor hired to resolve problem

    by Jim , 03/10/2015

    Furnace went out over night and Summit responded quickly the following morning. In spite of computer error code which indicated another course of action technician recommended replacing three parts at a cost of over $600. Furnace went out the following night and I contacted another firm. With the error code the technician immediately diagnosed the problem over the phone (it coincided with the recommended course of action in the manual for that error code) and replaced the part in an hour and furnace is worked fine. a $750 repair cost me over $1,500 and much inconvenience due to Summit's incompetence. The second technician inspected the three replaced parts saying they were perfectly fine and could be reused if necessary at some future date.

    Thanks for the great service

We have had a technician come out to our house and he was very knowlegable & helpful at explaining the problem to us. We very much appreciate the service you give to your customers.

    Response to review by Customer with CO detection: by Summit Mechanical Service

    by Jeff Aili - Project Manager , 05/13/2013

    This review is in response to the review listed as "Possible Home gas furnace inspection rip-off". Summit performed a heating clean & tune on a Coleman DGA natural gas furnace in Superior for Ellen Oakes. The person that wrote this review is a fiancee of Ellen's and was not onsite during "clean & tune". Technician onsite detected CO levels well above 200 PPM. This is carbon MONOXIDE which is dangerous. I say this, as the reviewer has this backwards with CO2 which is carbon DIOXIDE (which we breath out). Please visit the EPA website for more information regarding carbon monoxide in homes. Summit issued a waiver of liability and gave the owner a quote to replace the furnace at $2,377. The clean and tune service was provide for $83.35 with tax. Both values very fair. Summit strives for honesty, integrity and clarity. That is the purpose of this review. Summit has spoken with owner to recommend getting a 3rd party to visit home and test furnace for CO and cracked heat exchanger. On 5-13-13 approx 2 months after service, Summit followed up to check if owner had a 3rd party test furnace. (Summit recommended Superior Water Light & Power) Owner did not. We hope no harm is caused by CO issue due to lack of action on the owners part. Please contact Summit Mechanical if you have any questions. We serve our customers diligently with honesty & integrity, and continue to grow through referrals from happy customers!

    Possible home gas furnace inspection rip-off

    by Chip Puller , 03/16/2013

    Our home gas furnace was inspected on 4/15/13 and a high C02 level of 200 ppm the inspecter detected was claimed to be dangerous. Normal C02 levels of 600-800 ppm are acceptable. No where on the inspection report was the supposed dangerous levels of C02 ppm mentioned, . We are contacting another furnace inspector for their inspection of C02 levels before deciding what to do next. I feel the inspection fee was also too high. The quote for a replacement Miller gas furnace was also too high

    Happy customer

    Summit installed our Geo Excel Geothermal unit in March of '08. I can't say enough about how wonderful they were to work with. From the bidding process to the actual install they made sure we were completely knowledgeable and satisfied. They were highly respectful of our home, careful to clean up each day and did the job in the exact amount of time specified...absolutely recommended! They followed up a year later to make sure we were aware of the new tax credits, this to me, was above and beyond. The unit is performing as was promised, and we enjoyed a full winter of very low heating cost and a summer of nearly no cost air conditioning.
