Reviews from Carpentersville customers:

All work completed on time, under promise, over delivery. I was concern about getting work done in short time line. Even though he was busy with other customers issues, he still stayed on time and on task. I would trust his team on year around maintenance and service. Great job team! -Greg, Carpentersville

I lucked on Leith during a particularly cold day and the furnace went out. They were able to schedule me within a reasonable amount of time. Brian was courteous and knowledgeable. He got my furnace running in short order and when he was explaining what the issue had been and what he did to correct I never felt he was talking down to me. He is trustworthy and has become the only name in hvac I recommend to family and friends. As a result my mother, sister and in-laws use Leith exclusively as well. -George S., Carpentersville

Brian is very knowledgeable about all aspects of heating and cooling. He responds to calls promptly and completes the job in a sufficient amount of time. My air conditioner was working within 3 hours. -Chris
