Technicians arrived on time, fully equipped, and ready to get started. They arrived and explained each step of the process clearly and patiently answered all my questions, while welcoming my suggestions and ideas. Their professionalism, preparedness, and willingness to listen was appreciated.It was refreshing to see a female technician working confidently in the field—a positive reflection of how the profession continues to evolve. Her knowledge, professionalism, and willingness to answer questions and welcome ideas made the experience all the more positive.They were very accommodating and flexible, allowing me to arrange for a local independent scrap metal collector, who is also a friend, to pick up the scrap metal. I appreciated their willingness to accommodate my arrangements and work with me to find a practical and beneficial solution.The end result. It was a long day, and the crew worked virtually nonstop, finishing at 7:00 p.m. They cleaned up everything, removed all scraps and containers, and then took time to explain the operation of the newly installed units.Shout and big thanks to Veronica, Victor,Cory and Nick

Hamco recently installed venting through the attic and up to the roof for my microwave/range hood combo.Andrew from Hamco was available, pleasent, and thorough. He assessed and quoted and even came back during install to ensure everything ran smooth.Cheryl helped rearrange when weather postponed the work. Work was done within one week of assessing.The installers Cameron and Victor were knowledgeable, polite, and answered all my questions.I'd highly recommend Hamco for any HVAC jobs you might need.Thanks guys!

Had a HVAC replaced by Austin at White Pines Mechanical, and was very happy with the service and communication. The unit was a in a rental and had to coordinate with the tenant and Austin and set up install and communication went smoothly. Unit works great! Very happy with the service!

Had a heatpump and 3 heads installed in our home in July. Every time I come through the door on a hot day, I say a prayer. Not to a god, but to Andrew and the rest of the team at Hamco. I can't tell you how drastically our lives have improved. Andrew was very informative, helpful, great communication, very responsive at all hours of the day, happy to accommodate with my babies nap schedule. The installation team were very respectful and did an excellent job. We were pleasantly surprised that the job ended up taking only 1 day instead of the estimated 2 days.10/10 would use again and would recommend to everyone.

We recently had new furnaces installed at our co-op, and Victor and Veronika from Hamco were fantastic. You could tell right away how hardworking and kind they are. They were super professional, did great work, and left everything completely clean and tidy.

We had a new furnace and A/C unit installed by Hamco 7 years ago. We get both units serviced annually by Hamco. The technicians have always been very friendly, courteous, and professional. This year, there was a leak in the water line leading to the humidifier on the furnace. Hamco advised me that this was not covered by the furnace warranty. Regardless, they agreed to fix the problem without charge. Derek was great and he fixed the problem quickly and efficiently.

Got a new water heater from Hamco. The entire experience was handled in a professional and competent manner, from my initial phone call to the in-house consultation to the installation. The installers in particular impressed me with their friendliness, efficiency and competence. All told, had a new heater installed about 26 hours after my initial phone call. Felt the price was quite fair.

The team at Hamco are professionals! They just installed a new Furnace, A/C and Hot water tank, all in one day. They did exactly as promised, you would never know they were in the house. I wouldn’t call anyone other than Hamco. I give them six stars.

Najim came yesterday and worked 4 hours on the air unit. He did an excellent job and the system is now working. Very professional and I recommend this company to all who need a unit. Also they installed a new furnace as there were cracks in the system.

Very good customer service on the phone - live person there whenever you call. Called on Thu afternoon and Friday morning the technician - Najim - came to check the problem with my AC. Unfortunately the fixing estimate came to half the price of a new unit so we desided to order a new one. Same day they called me with an appointment for Monday morning! Today with the new unit Murray and Victor came early and installed it. After they finished cleaned after themself and put everything on its place in my basement. Amazing job! Thank you!

Right from the prompt response to my call, the honesty and integrity from the sales department when I was desperate to replace what I thought was a system in need of replacement, I was so impressed with this company.I wasn't able to get the original installation company to return a call, book me a service appointment, or acknowledge the fact that I had left emails, called and needed a service before I could use my ductless unit. It doesn't perform well to start with, so I wasn't going to start it up without a service and cleaning. After 3 1/2 weeks of the hottest month in history, I got tired of living in a convection oven, and finally found Hamco. Many HVAC companies don't service ductless units, and I was desperate at this point. Their team was friendly, efficient and professional. They didn't sell me a new unit when I thought I needed it, Christian cleaned it up, testing the unit properly and took the time to explain the size of the unit, why it was working the way it was, or why it WASN'T cooling as efficiently as I had been expecting it to, and gave me some potential future options if I wanted to upgrade. He left it running, with us finally having a/c for the first time this year! We couldn't be happier with their service and will only be using them moving forward! Thank you again Christian!!
