The heating system in my new built house was installed by Martino HVAC company. They were in my house twice during the warranty period, both times for high tuning of the equipment.
I can not comment on the results, they will be more obvious when the heating season starts.
But the employee that serviced our house was very professional and efficient during his visits. The order desk service was also impeccable.
I want to add that I spoke on phone to one of the professionals from the company because I had a general question regarding the furnace. I received the most detailed and satisfactory consultation.
Thanks!
