"This is the third time I have used Precision Temperature over the past three years for annual maintenance.

Just as we have in the past, we found them to be an honest, trustworthy heating and air company and I recommend them to anyone needing their services."

"Precision Temperature is who I call when my A/C is not working. They have been doing periodic maintenance on the two systems in my house which were 30 some years old and they got several extra years of life out of them.

We finally broke down and replaced both units this year and everything is working great!"
