The company was very friendly and courteous. Told me they would call and get a technician out. They did within an hours time. The technician Aaron was very informative on the situation and gave me options. Explained everything. Very please with the company. 5 star review

Excellent

Aaron was friendly, knowledgeable and efficient. Not only did he replace my water heater, but he made sure to check all of the surrounding pipes and gave me a few tips on long term care.

Matthew came by today and serviced my Marlo Water System. (New circuit board and top off media). Donovan had been by on 12/16/25 and determined the original board had malfunctioned likely due to the lack of a Surge Protector. I purchased a Surge Protector and installed it while waiting for the new Circuit Board to arrive. Now I'm set up and good to go. I've never been disappointed with anyone from Andreas. Always Knowledgeable and Informative. Even the communication from the Office Personnel offer Up-to-the-Minute status. Whoever does the hiring there is also doing an Excellent Job! Thanks again! Drew

Shopping with Andres Company was incredibly easy and stress-free. They installed my boiler in just two days, and the entire experience was excellent from beginning to end. This is hands down the best company in the Bethlehem area—I wouldn’t trust my business with anyone else. Doug was an amazing salesman: fair, honest, and straight to the point, which I truly appreciated. Everything was explained clearly, with no pressure or surprises. If I ever need service again, Andres Company will be my first call, and I confidently recommend them to anyone in the area looking for reliable, high-quality work.

Our furnace unexpectedly went out during a very cold and snowy weekend. Andreas was able to send a technician out within an hour to fix! Ivan was able to get our furnace up and running in no time!!! Thanks so much for your hard work and prompt service!!! Highly recommend!!!

Fast worker,very thorough explaining when checking everything, very nice.

We are glad Ryan was able to fix our oil burner this past week, the cold wind is back again! So we appreciate the quick servance , it's great to know you are nearby,and we can always trust your work!

Kevin T. solved a problem with my heating system that another company could not. His knowledge and dedication was so impressive. Very talented technician. Thanks Andreas

Matt was a great tech. Knew exactly what he was doing. A really great guy.

Jordon was our technician today for a routine service check of our heating system. He was courteous and professional. Explained every step of the inspection process and followed company policy of shoe covers (simple thing but shows professionalism and responsibility to the company).

Great company. Five stars in every category! This is my first experience with Andreas, very pleasant and professional. Definitely recommend them for plumbing or HVAC repairs. Top notch company

Did a wonderful job installing my whole house mini split system. Very professional and a pleasure to work with. System works great

Ryan was very polite and easy to talk to with how he explained what he was looking at and how he intended to resolve the issue. He spent a large amount of time going step by step with a diagnostic inspection of our heating system and once he found the issue he was quick to tell us and then fixed it in a timely manner. Would recommend

Alex was very professional and kept us informed every step of the way. Explained everything in detail. Highly recommend!

Cameron & Nathan were my techs for a new heating system and adding central air to my home. Both did a wonderful job, completed in a timely fashion and were very professional and personable. I would highly recommended the Andrea’s team for any needs!

I can’t be any happier, from the first phone call, to the follow up, timelines, communication and nice service tech! Just an overall fantastic job. I would highly recommend Andreas. Happy first time customer, Stacey Cheese
