Greenwood, IN HVAC Services

Building a new home? Remodeling or renovating? It’s an exciting time, and we’re here to make adding your HVAC system one less thing to worry about. Choosing the right equipment matters, but so does making sure it’s put in properly. Our team can help you find the right system for your space and budget. We install gas furnaces for dependable whole-home warmth, heat pumps for year-round efficiency, and boilers that deliver quiet, consistent heat.

If parts of your home stay colder than the rest—like a basement, sunroom, or room over the garage—ductless mini splits are a simple way to add heat without needing new ducts. For homeowners who want to save on energy, geothermal systems use the steady temperature underground to warm your home in winter and cool it in summer. And if you want a setup that does both efficiently, a dual-fuel system combines a heat pump and a gas furnace, automatically switching between them to keep your home comfortable no matter the weather.

Maybe your furnace turns on but never really warms the house, the air feels weak coming through the vents, or you’ve started hearing a noise that wasn’t there last week. Whatever the problem is, you shouldn’t have to tough it out in the cold or wait days for an appointment. Thiele offers fast heating repair services for all types of systems, including gas, electric, and oil furnaces, boilers, heat pumps, and ductless mini splits.

Our technicians handle just about every heating issue there is—systems that won’t turn on, uneven heat between rooms, weak airflow, or strange noises that don’t sound right. We also fix clogged filters, bad sensors, and worn-out parts that can cause your system to short cycle or shut down. If your heat stops completely, our emergency heating repair team is on call 24/7.

The last thing anyone wants is a cold house on a freezing night—but your chances of that skyrocket when your heating system doesn’t get regular care. At Thiele, our maintenance services are designed to keep your equipment running safely and efficiently, so you can count on reliable heating all winter long.

During a furnace tune-up, we clean burners and sensors, test the ignitor, and inspect the heat exchanger to catch early signs of wear. For heat pumps, we check refrigerant pressure, clean the coils, and make sure the system switches smoothly between heating and cooling. And for ductless mini splits, we clean filters, drain lines, and indoor units to keep every zone heating evenly.

Most visits take about an hour, and that small investment of time helps prevent breakdowns, improve efficiency, and make sure your home stays comfortable when the temperature outside says otherwise.

Most heating systems can last 12 to 15 years, but after that, they start to show their age. You might notice longer run times, uneven temperatures, or repairs becoming a regular thing. As your Greenwood HVAC contractor, we replace furnaces, heat pumps, and ductless mini split units, replacing them with modern systems that are quieter, more dependable, and far more efficient.

Today’s models use less energy while providing better heating. You’ll notice that the new heating system doesn’t have to work as hard to keep your home comfortable, and your energy costs can drop right along with it. If your old setup is past its prime or struggling to keep up, we can help you find a new heater that’s a real upgrade in every way.

Air purifiers work alongside your HVAC system to remove tiny particles like dust, pollen, pet hair, and other allergens that build up in the air. They’re a great option for households with allergy or asthma concerns—or anyone who just wants cleaner, healthier air throughout the home. We install whole-home air purifiers that connect directly to your ductwork, so every room gets the benefit. Our team also repairs and replaces older units, helping you choose a purifier that fits your home’s layout and HVAC setup.

Air cleaners go a step further than standard filters, capturing smaller particles like smoke, pollen, and fine dust that regular HVAC filters miss. We install whole-home air cleaners directly into your duct system, providing continuous filtration whenever your HVAC runs. If your system isn’t working as it should, we also handle air cleaner repairs and replacements. It’s one of the simplest ways to keep your air fresh and reduce dust buildup on furniture and vents.

When summer humidity settles in, your home can start to feel muggy and uncomfortable. Whole-home dehumidifiers help by pulling excess moisture out of the air before it spreads through your ducts. They’re especially useful if you’ve noticed condensation on windows, musty smells, or sticky indoor air. We install and repair dehumidifiers that integrate with your HVAC system, running quietly in the background to keep humidity levels balanced and your home feeling cooler.

When the furnace runs for weeks at a time, the air inside your home can get uncomfortably dry. That dryness can cause sore throats, dry skin, static shocks, and even cracks in wood floors or furniture. Whole-home humidifiers fix that by adding the right amount of moisture back into the air as it moves through your HVAC system. Unlike small portable units, these systems keep every room balanced—not just one. We install and repair humidifiers that connect directly to your heating system, helping your home feel warmer, healthier, and more comfortable all winter long.

Many heating and cooling problems trace back to the thermostat. When it’s not reading temperatures correctly or sending signals reliably, your whole system can struggle. We repair wiring, sensors, and communication issues, and also install modern smart thermostats that give you better control, more energy efficiency, and greater convenience. With the right thermostat, your home stays comfortable without wasting energy.

UV lights help keep your HVAC system and the air you breathe cleaner by eliminating mold, bacteria, and viruses as air passes through your ducts. Installed near your indoor coil or inside the ductwork, these lights run silently and continuously to stop growth before it starts. We handle both installation and repair, helping you maintain cleaner coils, healthier air, and a more efficient system.

Not every room in your home needs to be the same temperature—and with HVAC zoning, it doesn’t have to be. Zoning divides your home into separate areas, each controlled by its own thermostat, so you can heat or cool specific spaces instead of wasting energy on the whole house. It’s especially helpful for multi-level homes, finished basements, or families who like different temperatures in different rooms. We design and install zoning systems using smart thermostats and motorized dampers that adjust airflow automatically, giving you better comfort, lower energy bills, and more control over how your home feels every day.
