What Our Customers Are Saying

100% Satisfaction Guarantee

4.7

Based on 1271 reviews

This company is like a breath of fresh air. The tech was honest and upfront about the repair. I never felt pressured into paying $thousands for mysterious repairs or system replacement. The price very reasonable and the work was done in no time. I would recommend Haller to everyone. A definite five star experience.

Michele Fallstich

Connor is a very knowledgeable young man. I am extremely satisfied with the work done on my generator.

Great job and service.

Tech was very competent and friendly. Explained everything and then made sure I understood what was done. Safwan has done service and PM calls for me before and always was great.

Explained everything in detail- very up front and extremely friendly

Robert was able to come by and do his inspection early which was good. Did a thorough check on plumbing.

Albert DiGuilio

We have had the same technician, Ricardo, on our last to service calls. He is amazing. He is very thorough and efficient and is very knowledgeable. Thank highly recommended Haller and request Ricardo for your services technician

I think that the AIR-FITER FOR MINE A/C HEAT-PUMP WAS HIGH.

Omar & Carlos were totally professional, efficient and effective. They found the problem and communicated the solution and cost of repair.
It’s not their problem that the price of the repair was extremely high and quite frankly, excessive. That wasn’t their call.
Basically it cost $800 for them to install a $200 condensate pump — which is not a difficult installation.
But I really was not in a strong bargaining position — it’s over 100° now and will be for at least the next 2-3 days. I bit the bullet and paid the price. I needed the A/C functioning.

Phillip McGuigan

Responded on time, very personable, and completed the repair with no issues.

Haller was very professional and informative throughout the process. They even paid for me to stay in a hotel because it was so hot out during the install.

Dobt forget to send me Michael Rodrigues email address

Ryan was prompt, thorough and courteous.

Your guys came out to do routine maintenance on my minisplits that Deluxe had pit in 3 years,ago. They did a great job, and showed me how to clean the filters inbetween them coming. They also cleaned a minisplit my husband had put in for me. They did a wonderful job!

Very thorough and professional install of a new AC/Heat pump unit. Highly recommended,

Excellent technician

Deborah Truscello

They came very quickly in response to my emergency call when my hot water heater pretty much blew a gasket. I was very upset. Then Chris from Haller came & made everything right for me. Clean, neat, professional & nice. Wonderful!!

Safwan was terrific! He was dedicated in diagnosing our AC problem. Great technician!

Fast, professional, & reasonable estimate.

Tristan from Haller Enterprises did a wonderful job. The unit was installed so good it will never move or get ruined from the weather. It works great. He was a true professional. The new thermostat is simple to use. What a pleasure to have someone so knowledgeable. Thank you so much for a job well done.

Great service performed by Patrick. His service remedied the spigot issue. 5 ÷ stars for him.

Stephanie Meinhart

Robert N. was very thorough. He explained everything he needed to do and answered all additional questions I had. My parts warranty had expired and he apologized and explained how the things that caused my plumbing problems can occur.

did a great job and fixed another issue i was having!

Ricardo C performed the maintenance on our heat pump system. Thanks for keeping it running in top shape!
