What Our Customers Are Saying

100% Satisfaction Guarantee

4.7

Based on 1285 reviews

Service guys were great. Ricardo and I believe the other tech was Steve, we’re very personable and polite. Did what I needed done on the preventative maintenance on my A/C. i did think it was a little pricey, but what isn’t nowadays, running a company is not cheap . I will request them when it’s time to have the furnace checked out and cleaned. I hope Haller recognizes their employees and passes this along to them.

PLEASE READ THIS IF YOU HAVE A CAT OR ANIMAL GET STUCK IN YOUR VENT. I want to sincerely thank the people at baller enterprises for their incredible response to my emergency situation. We recently moved into a new house, and are unfamiliar with how the AC vent system is set up. My youngest cat somehow pulled a floor vent up and got himself lost/stuck for hours. My wife and I were besides ourselves and no one could help or cared when calling around, until we called haller. They mobilized a team and gave me a game plan of how we were going to go about finding him as this was not their first time dealing with this type of situation. I got lucky enough that he was able to find his way back out but the people at haller wasted no time getting people over to help and making me feel much more calm while I waited. If this happens to you, please don’t waste time calling around. Just call Haller. They will get you the help you are looking for. I have my cat back and couldn’t be more happy with how they handled themselves. Thank you Haller and especially Christy.

Very knowledgeable!!!

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.

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

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

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.

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