Real People. Real Stories

"Called Greg the day before and setup the appointment for Saturday. Greg showed up on time and went right to work and diagnosed the fact that the fan wasn't blowing due to a bird being stuck in the impeller. Greg removed the bird but the fan still wasn't working, he then lubricated the fan in hope that he could get it going instead of just replacing it which would have costed me a lot more money. It's great to find an honest service provider! Thanks Greg."
