We have used TE Certified for all our heating and electrical needs since moving to Woodstock. What has impressed me the most is their workmanship and responsiveness. They offer quality work at a fair and competitive price, and advise rather than up sell. All their technicians are highly trained and very accommodating. Recently, Joey Baka services our HVAC units and provided a quality finished product keeping us advised each step of the way. We are very satisfied with TE Certified and would recommend them highly.
