Heating and Air Conditioning Repair Services

No two homes are the same, and your heating and cooling setup might be completely different than your neighbor’s. That’s why we’re trained to repair a wide variety of HVAC systems, no matter who installed them or how long ago.

Furnace Repair

Furnaces warm your home by creating heat through gas or electricity and then pushing it through your vents. When parts like burners, blowers, or flame sensors fail, your comfort suffers. Our team identifies the problem fast and replaces worn-out components to get your heat back on track.

Boiler Repair

Boilers send hot water or steam through pipes to radiators or underfloor systems. When they’re leaking, making noise, or delivering uneven heat, you may have an issue with a pump, pressure valve, or airlock. We clear out clogs, patch up leaks, and fine-tune your boiler for a smoother performance.

Central Air Conditioner Repair

Central AC works by pulling heat out of your indoor air and pushing it outside. But when refrigerant runs low, coils freeze, or the compressor stops working, your home can feel hot and sticky. We diagnose the issue, recharge the refrigerant, and fix failed parts to ensure your home has the cool air it needs to beat the summer heat.

Heat Pump Repair

Heat pumps keep your home comfortable year-round by moving heat in or out depending on the season. If your system is short-cycling, blowing lukewarm air, or struggling to switch modes, the reversing valve or sensors may be to blame. We repair and recalibrate your system for consistent, efficient comfort.

Geothermal System Repair

Geothermal systems rely on a series of underground loops to regulate indoor temperatures. When the system loses pressure or the heat exchanger fails, efficiency drops. Our techs inspect your loop, check for leaks, and get your geothermal system running like it should—quiet, powerful, and efficient.

Ductless Mini Split Repair

Ductless mini splits are ideal for zoned heating and cooling, but even small issues—like dirty filters, leaking lines, or sensor glitches—can impact your ductless system’s performance. Our HVAC repair specialists clean, test, and tune your ductless mini split units so each zone feels just right again.

HVAC systems are complex, with high-voltage wiring, gas lines, and sensitive components that need expert handling. Trying to fix a problem yourself might seem quicker or cheaper, but it can create bigger issues or even safety risks.

Let Thiele’s skilled technicians take care of it the right way so your heating and air conditioning comes back safely and without any added stress.

Indoor Air Quality Repair Services

Your HVAC system plays a big role in keeping you comfortable, but your indoor air quality (IAQ) system plays a big role in keeping you healthy. These add-ons—including humidifiers, purifiers, and smart thermostats—help balance air conditions and reduce contaminants in your home. But like any equipment, they sometimes need repairs to keep working their best.

Air Cleaner Repair

Air cleaners are designed to pull particles like dust, dander, and allergens from your air. If your system isn’t capturing pollutants the way it used to, it might be due to a clogged filter, a bad motor, or worn-out internal parts. We’ll inspect the unit and restore performance so you can breathe easier.

Air Purifier Repair

Whether your system uses HEPA filters or ionization, air purifiers are crucial for removing bacteria, smoke, and other airborne irritants. Electrical failures or blocked filters can cause them to stop working. Our team will identify the issue and get your purifier running again for cleaner, healthier indoor air.

Dehumidifier Repair

Too much humidity in your home? If your dehumidifier is struggling, it may be dealing with a blocked drain, refrigerant leak, or broken compressor. We troubleshoot moisture issues, clear clogs, and fine-tune the system so your home feels dry, fresh, and balanced again.

Humidifier Repair

When Indiana winters hit, a whole-home humidifier helps add moisture to overly dry air. If yours isn’t working right, you may be dealing with mineral buildup, stuck valves, or wiring trouble. We’ll inspect the unit, replace problem parts, and recalibrate it for steady comfort.

Thermostat Repair

Not every HVAC problem starts with your heating or cooling unit. A failing thermostat can cause temperature swings, short cycling, or complete system shutdowns. We check wiring, update settings, or install a new thermostat when needed for accurate, reliable control.

UV Light Repair

If your HVAC system includes a UV germicidal light, it helps kill bacteria and mold as air flows through. Over time, the bulb can burn out or the ballast may fail. We test and replace UV components so your system keeps filtering the air and reducing allergens where it matters most.

Whether you’ve noticed poor air quality or just need your thermostat looked at, Thiele Heating & Air Conditioning in Fishers is here to help. Don’t have an IAQ system yet? We can help you choose and install the right equipment to support your comfort and wellness.
