Is Your HVAC System Making a Strange Noise?

Normally, a properly functioning air conditioner makes occasional pops, hisses, rattles, and a quiet hum that shouldn't be a cause for concern. However, if you notice loud humming or buzzing noises, your unit may be malfunctioning. Although our office is in Fort Wayne, we proudly service all of New Haven, Indiana, and beyond! Call us today to find out if you live in our service area.

Tune Up Your System

Some may try to sell you a 'brand new car' when all you really need is an 'oil change.' At Hartman Brothers, we approach your situation as if we were spending our own money. We'll conduct an in-home assessment and 12-point inspection, giving you an accurate, in-writing picture of how your system stacks up against today's current models. We will never recommend or sell anyone anything they don't really need. You'd be amazed how much we've saved our customers just by looking under the hood.

We'd be delighted to visit your home, assess your current situation, and offer thoughtful, easy-to-understand recommendations in writing.

"Always a tremendous experience with Hartman Brothers. I have used them for more than 25 years and gotten to know their people more like friends/family than vendors... because that's exactly how they treat their customers! Always a pleasure to deal with and their work is exceptional as a bonus. Would give them 6 Stars if it was an option."
