What our customers have to say

Chris C.
professional, punctual, high-quality, great value

“The tech was very helpful. We weren't sure we had a problem or not so he reprogrammed the thermostat since it was the easiest and cheapest place to start. He helped me locate a manual online so I could program it myself in the future, we really appreciated that since I was unable to find one myself. The system has been working much better ever since. Thank you”
Brittany W.
Would definitely recommend Mark and Postma

“Had some leaking/flooding from an unknown source, Postma was able to schedule a plumber to come out the same day. Even though the plumber, Mark, was running behind with his other emergency calls after the cold snap he fit us in at the end of his day. Mark was kind, thorough and accurate in diagnosing the issue. Would definitely recommend Mark and Postma to anyone with a plumbing issue.”

“The whole team at Postma was professional and timely! When our furnace broke in the middle of a heat wave they were scheduling it’s replacement in less than a week! Would recommend their services to anyone needing heating or cooling assistance. The work is clean and they want to make sure you’re happy with everything!”
