Great response time, knowledgeable trustworthy and great people to work with. Our previous company…read moretold us we needed a new system which was only 9 years old. Lake Shore Heating and Cooling assessed the system, made adjustments and corrected issues created when the system was installed. The charge was so reasonable and they confirmed our system did not need to be replaced. I will never use any other company.

The mini split installation required almost $550 (out of my pocket) to local service contractors for modifactions over the next year to correct problems directly related to the Thelen installation. A zone heating modification never worked properly after a $2500 (paid) installation, Two Techs spent four hours reviewing the problem and stated that the system design was was incorrect.

The office/account manager then sent this bill to a collection agency. I documented all of the problems and expenses and provided it to the management who refused to discuss the issues until I paid the collection agency. Now I am dealing with a collection agency for a $624 bill after spending $30k here.
