"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."

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.

"I recently worked with Trust1 Services and the experience was fantastic. A technician came to my home and informed me that my system was outdated and broken. They provided me with options to either repair or replace it, but without any pressure. We decided to go with the replacement as it was the more economical choice in the long run. During the process, the owner, Anthony, stopped by to check on the job and express his gratitude for our business. He even brought pizza from Town Spa after learning that it was my favorite place. Anthony shared some stories about how he got started in the business, making the entire experience even more enjoyable. This was hands down the best experience we have ever had with a contractor. The work was exceptional, and the overall experience was amazing. Anthony truly impressed us."
