What Customers Say

“I’ve been using Limcan for many, many years. I’ve had quick efficient service any time I’ve had a problem with my furnace or A/C. The office staff who take the initial calls are friendly and knowledgeable. When you finish the call with them, you feel like your problem is going to be well looked after and that you, the customer, is very important to them. The techs are skilled, always polite and only do what needs to be done (i.e. they don’t try to up-sell or make unnecessary repairs). Nick was the latest tech to fix a water leak from our humidifier and did an excellent job.”

- Ron S.

“Pete did a thorough job checking our a/c system. Professional employee, he presented well. He told us that the breaker for the a/c was too big, which another company didn’t mention in the 7 years they were checking it. This is my first year dealing with Limcan, I think we’ll stay with them.”

- Marra M.
