Great experience. They came right away and addressed my concerns. Sam (the technician) was super knowledgeable and helpful. Will definitely be using for my hvac needs going forward

Sam & Tommy came to check my heating system. They were very neat,courteous and did a fine job. I will definitely call them again for any HVAC needs in the future.

Could not be happier with the service I received today. 90+ degree weather and they sent a team out the same day, diagnosed my issues and repaired them in the same visit. Would be a pleasure to refer them to all. Great job by Xtraire inc.

– James Wheeler

Great service and work done by Xtraire. I highly recommend them. I have been using them for over 8 years now for my business and home.

– Michael Richer

Another fantastic experience with Xtraire today! Euryel came today to check our unit we installed around a year ago. He was extremely friendly, professional and clean. Always such a pleasure working with all Xtraire staff!

– Victoria Stacy

Our technician was friendly and very knowledgeable. He arrived promptly. I've been an Xtraire customer for at least 20 years. Very satisfied with their service.

– Steve Boshko

"Our furnace quit working on a Sunday night in January. Northern had a tech at our door in under an hour. He had it running again in no time—and didn’t try to sell us anything we didn’t need. Can’t recommend them enough."
