I recommend HAMCO 100%. They were punctual, professional and polite. I had Andrew come out to my house today and couldn’t say enough good things about him. He was so patient with answering all my questions and answered everything in a way I understood. He was fast with his work and gave me peace of mind. If I ever have any future issues I will be requesting Andrew!!

Very happy with the service. Called today because air wasn’t working. A technician was here within 1/2hr. Explained what was going on and even taught me something about my thermostat that I was unaware of. Very impressed. Even during annual maintenance they are always prompt and knowledgeable. Highly recommend.

I recommend Hamco Heating & Cooling. A technician came to my house to do an annual maintenance check up on my furnace. The technician arrived when Hamco said they would and the technician did a thorough check up on the furnace and explained to me what he was doing every step he took.

HAMCO installed a new AC and Furnace and has provided annual checkups. Service is always friendly and prompt and I would highly recommend their service for either a new unit or to keep your older equipment running well.

Everything about the experience was equal to or above our expectations. service was provided on a timely basis, Andrew at the office was very good, the service people were pleasant and always left our premises as clean as they found them.
An issue arose as to the meshing of the air conditioning unit they were installing and our furnace. They had… stated that there would not be a problem and when it turned out that they were wrong they went above and beyond giving us a new furnace, complete with a new warranty, even a better furnace than the one they installed a few years earlier for no charge
