“We had Luke come to give us advice on a better way to heat our house. He was very honest about his thoughts on the best option, not just trying to sell us the most expensive. We ended up going with what he suggested and it works great. Luke and his brother are very respectful- when they came to install the heat source they would take their shoes off. We told them they didn’t have to but they did. How many contractors can you say that about. I would recommend these guys for sure.“

“My home has 2 HVAC systems and I use Haller to maintain them. I have also used them for plumbing issues. They service my HVAC units for both Summer and Winter. I have never had a break down due to maintenance issues. They advise you a day before to remind you of your service time. You also get a call when your technician is en route to you. The technician advises you of any issues that need to be addressed and usually has the part available in his truck. They are always courteous and take note of any issues or concerns you might have. I highly recommend using Haller.“

Special thanks to Jeff, the service manager, for making this happen. This company is very reliable and I couldn’t be happier!“
