What Homeowners Say About Limcan’s HVAC Services

“First experience with Limcan. My father-in-law has used them for years – I can see why. Totally amazed not only on their response when our AC died on one of the hottest days of the year, but the friendliness & professionalism of the tech (Jake, I believe). Focused on the task at hand but also took the time to respond to my questions. Definitely recommend Limcan. You won’t be disappointed.“​

“Salem came earlier than scheduled, after the company confirmed it was OK (it was). He quickly got down to work, performing the maintenance on both the A/C and the furnace. He found an issue with the A/C, which he said he will report so that the company will schedule a separate service call. Once he was done, he cleaned up, reported the results, and concluded the service call. No muss, no fuss, just as it should be.”​
