What Homeowners Say About Limcan’s HVAC Services

From consultation, to installation and information, the team at Limcan were incredibly helpful, professional and knowledgeable. From the time Kathy came for a consultation until the time that Marcus and Luke fired up our new HVAC was less than 24 hours, accommodating our every need and providing flexible financing options. Would highly recommend!“​

“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.“​
