Aim High was awesome. Twice I had a heat emergency and they were able to service my system the same day. Just had cleaning and maintenance done and super pleased with the services provided!

I can not recommend this company enough. We had a carbon monoxide leak in the middle of the night. Fire department found the source quickly. It was the furnace. We called AIM High the next morning at 8 am. They were here by 10 AM to evaluate the situation. Back the next day to install a new furnace. We shopped around and Aim High gave us the best price. Their technicians are also top notch. Very grateful for the honest and fast work.

I highly recommend Aim High! They replaced our old broken furnace with an updated one, and the cost was reasonable. They did not press us to spend more than we wanted to. David, Chris, and Cameron were all very professional (both in-person and on the phone). They took care of the issue quickly and efficiently so we weren't without heat for very long. After the installation, they cleaned up after themselves, and came back a few days later to check to be sure that it was all working properly. We had lots of questions along the way, and they were very patient and knowledgeable.

Aim High has amazing technicians -- specifically Damien and Andrew. They take the time to explain what they are doing, charge fair prices, and even came out after hours to fix an issue a couple days after I had the furnace serviced and didn't charge anything extra. Super professional, very timely and great guys.

Aim High has continued to provide outstanding service to me for over a decade. I have spoken with and met several of their staff and technicians and they all have been very professional, as well as always helpful and honest. When, after years of having inspections and maintenance done on my old furnace, it became necessary to replace it, they took the time to explain the options, made the process easy and I had new, updated equipment the next day. They have always been available for questions and ready to send a technician out if there are any concerns. If you want a stress free experience with an HVAC company, I highly recommend Aim High HVAC.

Aim High is an outstanding HVAC service provider. They make sure to get your appointment scheduled at your earliest availability and everything is well documented and professional. They offer you a formal quote before any work is done and they honor not going over that price. They have come out to diagnose my air conditioning and recently a potential carbon monoxide leak in my furnace. They were very prompt and made sure to fix what was needed immediately to put my family at ease. I can't thank this company enough. Cameron, Damien and David Reeg are top notch professionals and my family can't thank them and this company enough. They will always be on my speed dial if ever needed again. Thank you.
