"Outstanding service!!! We've been with North Star since our new install in 2020 and have continued our annual service contract with them. 5pm on a hot Saturday and no cold air. Made one phone call and Kole was to our house AND fixed the system in about an hour!!!"

"We have heat! Thank you for your quick response to our need for heat this time of year. The install went in without a hitch and the young men who did the job were not only friendly but very competent. Thank you North Star for your quick and efficient turn around."
