Set to Cool but Blowing Hot: Air Conditioning IssuesIf your HVAC settings appear to be correct, why in the world is your air conditioner blowing hot air? The most basic function of an A/C is to deliver cool comfort, so if you’re feeling a warm blast from the vents instead, something’s definitely amiss. It may be a simple matter you can resolve yourself or it may require diagnosis by a qualified technician. Here are some scenarios that might be at fault if your HVAC settings are blowing hot air instead of cool.

"We purchased our home just a few days ago and the heat was not working, and we were in single digit temps in this area. Josh, our tech, came out and checked everything out and discovered it was a programming issue on the digital thermostat. He set it correctly and heat is now working. The level of service of Hartman is phenomenal! Vickie in the office deserves a big thank you as the house was at 45 when I called and she saw to it that we were worked into their busy service request schedule."

"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. "

"Had to call to have our furnace checked out since it stopped working. Called Hartman Brothers at 8:00 a.m. on a Friday and they had someone come to the house that same day. The service Tech was outstanding and delivered great customer service. He explained what he did and had s fixed in less than an hour! Highly recommend Hartman Brothers!"
