Customer Testimonials

Our customers consistently praise our exceptional service and attention to detail, highlighting the positive impact we've had on their experiences.

Green Head Heating did the HVAC on our large new construction custom home. They have more than taken care of us from start to finish. Everything was VERY well thought out. They were knowledgable with energy credits, which is often times missed! This was a trade that was very important to us as it is inside your walls. I am certain we have the BEST system. They truly didn’t miss anything! Would highly recommend!

Brittany A.

Ryan has the exact experience to make sure you’re getting the climate control that your home needs. His knowledge is extensive and he always has an answer to every question and on top of that he’s pleasant to work with. Ryan and his main tech Tristan have done many high quality HVAC installs that I have seen in the last year and I couldn’t imagine trusting anyone else for the job. Thank you, Greenheads!

Karlan S.

We decided to replace our very old gas furnace with a newer and hopefully quieter furnace.  We contacted Greenhead because they were a smaller, local business.  Everything about the process was excellent.  Best of all the furnace is exceptionally quiet.  Thanks Greenhead.

Bruce R.

Would recommend! Our heat cut out during a cold snap - I called Greenhead the next morning and Ryan was at my house the same afternoon. He quickly diagnosed a faulty switch in our furnace and was back that evening with a new part! Pricing was reasonable, especially given the urgency.

Eamonn K.

I had Greenhead out to do service on my gas furnace and heat pump. Ryan was very professional and helpful. The service was very reasonably priced even though they were there in the evening! I would recommend them to anyone.

Lindsay P.

Came same day when we had no heat. Worked quickly to find the issue while explaining everything he was doing. Really took the time to make us feel like a valued customer not just a number. Also the pricing was very fair which in todays economy is always so helpful... we will be using this company for all future heating needs
