• I had a brand new unit installed by Hamstra about a year ago in my new home and it has been working flawlessly. I have also had 2 complimentary service appointments since and both times, the technicians were professional and efficient.

• First dealing with the Hamstra HVAC and everything from start to finish was impressively easy. Our ailing older unit was not quite on its last legs but it was close. Mike, from consulting and sales, explained all our options and made us feel like we were truly appreciated as new customers. All of the options that were needed were clearly explained and explored prior to installation. Then today the installation crew came out (Marc, Joseph and David) and went far above and beyond to make sure the experience was top notch. They were out exactly when they said they would be (0700) and were wrapped up and done by 1200. Not only was it done but it was tested, certified and done correctly. They thoroughly cleaned up and made sure there were no mars on the roof and even though they had to modify our existing air return, cleaned up that completely before completing their job. They then went through the system and how it worked to the point that I am pretty sure anyone would have understood how to operate the new system. The system itself was quite an investment into the property but needed to be done and we did not realize how loud our older system was until this one came on. It even made a dramatic difference in the living area which is the farthest away from the system. Normally there was always between a 3-5°F difference between the back of the house and the front of the house. Now it is pretty spot on across that house which is nice. It moves air more efficiently and delivers cooling to the whole house. Thank you all for such a painless experience and definitely would recommend them for any of your HVAC needs.

• I can't say enough good things about Hamstra Heating and Cooling. Right from the first phone call, I felt the lady that answered the phone was listening attentively to me. Ryan came out to speak with us and find out what we needed for AC. He took his time, explained everything very well. The rest of the team that came to do their part - were wonderful. Dave came to take measurements. The previous company had taken our existing structure down but also took all the sheet metal that went with it. Dave had to redesign it. Then David came with Marco and Andrew to install our new system. They also did a great job. I really felt that we mattered as customers. You can tell when people are doing their best, and that they care about what they are doing. We are so grateful to have found Hamstra. This is a company that actually cares about their customers, does good work and has good communication. I wish I could give them more than 5 Stars. Thank you!

• Excellent service and a fair priced product. The install was neatly accomplished. It was tested, and it is quiet and efficient. I give Hamstra six stars. Their communication and follow up service is excellent.

  Patricia B.★★★★★

• Semi-annual maintenance. The maintenance inspector did a fantastic job and kept me informed about what he was doing and why. Professional at all times. Arrived on time as scheduled.

  Debbie S.★★★★★

• We have had great, prompt service from Hamstra, for both maintenance and repair of our furnace and AC. We chose them to add a mini-split at our residence because they have been great for the 3 years we have used them. They are clear about our choices, thoughtful about potential options that save us money, and always prompt and thorough in what they do. Could not be more pleased.

  Debra T.★★★★★

• Richard performed a service check on my furnace. He was friendly, knowledgable, and very helpful.

  Jim S.★★★★★

• Great, friendly service as usual.
