Cannot say enough good things about Mark, he is a perfectionists perfectionist. Mark came to fix our furnace after our fan caught on fire. He had to replace the motor and do a lot of rewiring since it was not done correctly the first time. It was a scorching hot couple of days and he stayed until the whole job was complete. He even fixed the lock on our back door . I would highly recommend this company to anyone and I will. You wont find anyone with more integrity then Mark.
