Tyler is an Outstanding service technician and it was our pleasure having him do the work on our SUMP PUMP unit.
OUTSTANDING SERVICE !!! THANK YOU !!!

We were extremely happy and impressed with our Haller technician Andrey P. It was clear that Andrey took great care and pride in the work he performed during our maintenance call and we are very confident in the results. We would recommend Andrey to anyone!

Connor Bradshaw

Great work all around providing honest and informative assessments.

Andre was extremely professional and very informative. It was an excellent experience.

Tabish Chaudhry showed up on time. He checked all the plumbing and fixture operations in a timely manner. All part of Haller's preventative maintenance program. Clean and neat.

Omar did a great job explaining to me the defrost process of my heat pump inspection and that everything was working as intended.

Excellent service. Very thorough.

Matthew Haskell

great, professional service and solid pricing.

Great job had to endure 160 degree attic temperature.

Julia Nash-Black

Very personable and professional and solved the problem. Made my day!

Very efficient and friendly.

I appreciate Jaren for answering all my questions and doing a well done job maintaining our AC😊😊

Our AC went out early July, and the temperature inside the house approached 90 degrees. The company that installed the unit would be unable to come out to fix it until the end of July. We called around to a bunch of places, finally landing on Haller. They sent someone out within a couple of hours. Justin, the tech who responded to the emergency request, quickly diagnosed the problem and provided a detailed estimate. Our AC was back up and running within the hour. Very appreciative of the dispatcher who fielded our request and of great Justin’s work.

Another technician, Mistah, came out to our house recently for maintenance on a mini-split. There were quite a few repairs needed, as it was no longer cooling efficiently. He diagnosed the issue quickly and was back the next day to complete several repairs needed + a cleaning. He was very thorough and the unit is now working great.

Ricardo has also been out to our house a few times for maintenance and cleaning, and has done great work. All of our experiences with Haller have been great so far and I’d recommend them to anyone.

Brian from Haller preformed the annual , a c system inspection under my maintenance contract. He was very informative regarding our current system and its potential lifespan.

Mike was great. Very friendly and honest. Kept me updated throughout the installation process. Cleaned everything up and put everything back where it belonged when he finished. Wonderful job.

Tyler Durgin did a great job today! We are very pleased with Haller and their service.

Amazing!

Carl H works on my Kohler Generator every year. His professionalism and his knowledge is outstanding!! I only request Carl H for my yearly service.

I had a minor leak and called Haller they came within 2hrs. The two techs were very nice and professional they fixed the leak very quickly and also gave me a few hints about the humidity control unit. They also noticed that the outdoor condenser was sitting 2 close to the house and said they would make a appointment to move it for no charge. It has been a pleasure working with Haller I would highly recommend them. The service was great. Thank you Haller

Michael giordano

extremely professional did the job in a safe timely manner would highly recommend them to do any plumbing jobs. They replaced my hot water tank and water filter system. Both workers did a great job and will recommend them HIGHLY!!!!

Always a good job.

Matthew Haskell

Wonderful experience as always. Haller Techs know what they’re doing; they can articulate the problem and solution very well. Prices are fair and scheduling is good. Thanks Ricardo for your professional service!

Technician (Taleem J.) was courteous and seems efficient and knowledgeable.

Safwan went above and beyond. He moved a heavy hose holder to the front of my house. He explained what he was doing. The bulb was out in my attic a place I no longer climb up to. I gave him a new bulb and he replaced it. He was very helpful and I appreciate his thoroughness.
