"We could not be happier with our service, estimate for a new system and most of all offering to but coolant in the system to give us AC until new system is installed."

"I had an excellent experience with Hartman Brothers from start to finish. After dealing with an incomplete and frustrating repair from Peterman Brothers, Hartman Brothers was a breath of fresh air. Their technician spent several hours thoroughly troubleshooting my tankless water heater, walking through the issues clearly and professionally. There was no upselling, no pressure, and no shortcuts—just honest, methodical work.
Based on their findings, I chose to upgrade to a new tankless water heater, and the decision was entirely mine. At no point did they try to push a sale or steer me toward anything unnecessary. The installation was clean, the communication was excellent, and the entire process felt transparent and trustworthy.
It’s clear why they have such a strong reputation in the Fort Wayne area. Their professionalism, responsiveness, and genuine customer‑first approach really stand out. I’m very happy with the new system and with the service I received.

In homes heated by a furnace, setting the temperature back at night ensures energy savings. That’s not necessarily the case with a heat pump, however. In order to avoid turning on the backup electric resistance heat during the recovery period (when the unit is working to get back to your comfort temperature), the heat pump's thermostat needs to work in a special way.
