"Having cooling issue with 2nd floor central air unit on one of the hottest days in recent memory . Called prestige early AM and they responded with service tech within the hour. He quickly diagnosed problem and made recommendations, one of which was to replace current equipment with new equipment. This sounded extreme but after he fully explained the situation we decided to follow thru on his recommendation. A sales rep from Prestige was on site in less than 2 hours and provided a proposal to replace current unit , which was accepted . The following day 5 workers showed up completed the removal of old unit replaced with new unit in less than a day. All 5 workers were polite and did their jobs efficiently. By 1 PM that day, 24 hours after accepting their proposal , the 2nd floor was being cooled by a brand new AC system on another very hot day."

Growing up, my Dad had a someone for just about every issue that life could throw at him. Car’s making a funny sound? “Call Mr. Genese.” No hot water? “Call Mr. Martin.” Need a sport coat for my first job interview, “Call Mr. Antista.” Those people cared about my Dad and his family, they did great work, and most important, their advice could be trusted. Yellow Dog is bringing back old school customer service, with plumbers and HVAC technicians who are highly technically competent, and more important, who really care about your family and can be trusted to give you the best advice. We believe that old school customer service, paired with the latest technology to make setting up your appointment and communicating with us easy, and of course the highest quality work is what our customers deserve. Thank you for taking the time to learn a little more about us, and we hope you’ll give us a chance to earn your trust. We’re Yellow Dog – and we’re always by your side. Pat Dunn, CEO

In 2008, Landry Mechanical Inc Plumbing HVAC & Electric began serving residents throughout Worcester and Middlesex County. We started out just serving 20 systems a year and working on systems that our competitors ignored, such as wood systems or alternative energy systems. In putting our customers first, our reputation for quality work grew, as did our business.
