Anyone who’s spent a full year in Greenfield knows it’s hot and sticky in July, cold and windy in January, and somehow the in‑between seasons manage to throw in a little of both. That kind of rollercoaster keeps your HVAC system working hard, and sometimes, it needs a little backup.
That’s where Airtron comes in. We’re here to keep your home comfortable, no matter what Indiana skies decide to send your way. Whether it’s an AC that can’t keep up, a furnace that’s ready to retire, or just time for a good tune‑up, we’ve got you covered.
We also know Midwestern air brings its fair share of dust, humidity, and allergies. That’s why we offer indoor air quality solutions to help your home feel cleaner, fresher, and easier to breathe year‑round.

We specialize in AC repair and the installation of new air conditioning systems, including energy-efficient units. Our HVAC experts are well-versed in all cooling systems, so whether you need a new unit installed or an AC unit repair, Aitron provides the peace of mind you deserve.

From furnace repair to installing a new furnace, we'll make sure your HVAC needs are taken care of. Our technicians will even come directly to your home to examine your current heating system. We also have a transparent communication process, so you'll fully understand your options before making any decisions.
When something goes wrong with your heating or cooling, you don’t want a hassle — you want help you can trust. At Airtron Greenfield, we keep things simple: show up when we say we will, give honest advice, and do the job right the first time.
Our certified technicians are local pros who live and work in the same Indiana weather you do. They’ll take the time to explain your options clearly, so you always know what you’re getting and why.
And because prevention beats repair every time, we offer easy maintenance plans that help you avoid last‑minute breakdowns and keep your system efficient year after year.
Dependable, neighborly, and always ready to help — that’s Airtron.
Skyrocketing energy costs can suggest an HVAC system is working overtime or running inefficiently.
Worn components or leaky ducts can often cause hot and cold spots throughout your home.
Banging, rattling, or squealing sounds may mean parts are loose, worn out, or in need of repair.
Power failures, faulty wiring, or malfunctioning components can prevent your furnace or air conditioner from starting altogether.

Jean was very thorough with our recent tune up service. He was also very professional and courteous. Airtron also did a nice job coming out quickly to get us back up in running when our system went out over a weekend. Recommend.
