Meridian Hills, Indianapolis HVAC Services

If you’re building a new home, starting from a teardown, or adding central heat for the very first time, Thiele makes sure your system is designed and installed the right way from the start. Gas furnaces are the most common choice, delivering steady whole-home warmth through a central duct system. Electric furnaces are sometimes chosen for smaller homes or as a more eco-friendly setup, while oil furnaces are still a fit for certain older-style properties in Indianapolis. Boilers remain a reliable option too, whether you need a classic cast iron model with radiators or a high-efficiency condensing unit paired with baseboards or radiant floors.

For families considering heat pumps, we install air-source models for year-round comfort, geothermal systems that draw heat from underground for unmatched energy efficiency, and ductless mini splits that bring zoned heating to areas that are difficult to keep warm.

When your heat goes out, it only has to be about 40 degrees out to cause the temperature inside your home to drop dangerously fast. A gas furnace might refuse to ignite, leaving the blower running with nothing but cold air. Boilers can lose pressure, develop leaks, or struggle to circulate hot water through the system. Heat pumps sometimes get stuck in cooling mode, ice over, or short cycle every few minutes. Even ductless mini splits can fail to respond, leaving a room completely without heat. 

At Thiele, we handle both routine and emergency heating repairs for every type of system in Meridian Hills. Our technicians check ignitors, burners, pumps, refrigerant levels, sensors, and electrical connections to get to the root of the problem. We explain what we find and move quickly with the heating repair so you don’t have to spend another night in a cold home.

The best heating system is the one that just works when you need it. Regular maintenance makes that possible. At Thiele, we take care of the behind-the-scenes details that keep your system running the way it should. We highly recommend scheduling heating maintenance in Meridian Hills each fall. You’ll also want to learn more about our Annual “Rewards” Service Agreement, Thiele’s maintenance program that includes seasonal tune-ups, priority scheduling, and a 15% discount on parts and repairs.

Furnace maintenance helps prevent breakdowns by catching dirty burners, worn ignitors, or airflow restrictions before they turn into big issues. Heat pump maintenance keeps your system running efficiently year-round with refrigerant checks, coil cleaning, and electrical testing. And for zoned comfort, our ductless mini split maintenance includes deep cleaning, filter service, and full system inspections to keep each room heating like it should.

Most heating systems hold up for 15 to 20 years, but nothing lasts forever. As they age, they need more repairs, burn more energy, and often struggle to keep the house evenly warm. If your furnace, boiler, or heat pump is constantly giving you trouble—or your bills keep climbing—it may make more sense to put that money into a new system.

At Thiele, we replace every type of heating system found in Meridian Hills homes: gas, electric, and oil furnaces, heat pumps, ductless mini splits, and boilers. We’ll walk you through your heating replacement options, explain what makes sense for your home, and install the new system the right way. The result is immediate: steady heat, lower costs, and one less thing to worry about when the temperatures drop.

Air purifiers connect to your HVAC system and clean the air before it circulates through your home. They capture dust, pollen, mold spores, and pet dander—things that regular filters often miss. In Meridian Hills, where seasonal allergies can flare up in both spring and fall, a whole-home purifier can make a noticeable difference. We install systems that treat the air in every room through your ductwork, and we also repair existing purifiers so they keep doing their job year after year.

Air cleaners take filtration a step further, using advanced technology to trap smaller particles like smoke, fine dust, and allergens. They’re a good fit for homes with pets, allergy sufferers, or older ductwork that tends to stir up debris. We install whole-home air cleaners directly into your HVAC return ducts so they run whenever your system does. Our technicians also handle repairs and replacements to keep them working effectively in Meridian Hills homes.

Indiana summers bring plenty of humidity, and homes in Meridian Hills certainly feel it. Too much moisture can leave basements damp, cause condensation on windows, and make the whole house feel sticky. Whole-home dehumidifiers connect to your HVAC system to pull excess moisture from the air before it circulates. Thiele installs and repairs dehumidifiers to help your home stay cooler, drier, and more comfortable through the summer months.

Winter heating often dries out the air indoors, leading to dry skin, sinus irritation, and even cracked wood floors. A whole-home humidifier adds just the right amount of moisture back into the air as it moves through your HVAC system. For families in Meridian Hills, this helps ease common winter discomforts while protecting your home’s wood floors and furniture. Thiele installs and repairs humidifiers that keep your home’s air balanced when the heat is running.

If your thermostat isn’t working right, your whole HVAC system can feel off. In Meridian Hills homes, we often find thermostats with bad sensors, loose wiring, or outdated technology that can’t control today’s equipment. Sometimes a quick repair or calibration is all that’s needed; other times, replacement makes more sense. We install modern smart thermostats that give you precise control, energy savings, and the ability to adjust settings from anywhere.

UV lights are installed inside your HVAC system to neutralize mold, bacteria, and viruses as air passes through. For households in Meridian Hills dealing with allergies or respiratory concerns, they provide an added layer of protection. UV lights also keep HVAC coils cleaner, which helps your system run more efficiently. Thiele installs and replaces UV HVAC lights in ductwork or near coils, depending on your setup.

Many larger or multi-level homes in Meridian Hills have uneven temperatures—upstairs rooms run hot while basements stay cool. HVAC zoning solves this by dividing your home into separate areas, each with its own thermostat and airflow control. That way, you only heat or cool the spaces you’re using. Thiele designs and installs zoning systems with smart thermostats and motorized dampers, and we service existing systems to make sure they deliver comfort where you need it most.
