Heating and Air Conditioning Replacement Services

At Thiele Heating & Air Conditioning, we help homeowners in Lawrence find HVAC replacement options that fit how they actually live—not just what’s on paper. Whether you want something similar to what you had or you’re ready for an upgrade, we’ll help you figure out what makes the most sense for your home.

Furnace Replacement

Furnaces heat your home by pushing warm air through ductwork powered by gas or electricity. Most last 15–20 years, but efficiency drops long before then. If yours struggles to heat evenly or kicks on constantly, it could be time for a furnace replacement. We’ll help you choose the right size, fuel type, and efficiency rating for steady warmth and lower bills.

Central Air Conditioner Replacement

A central AC system removes heat and humidity from your home through a closed refrigerant cycle. When it’s 10–15 years old, it may cool less effectively and run up your energy costs. With a central air conditioner replacement, we’ll size the unit properly, recommend modern features like variable-speed compressors, and install for long-lasting comfort—even on those 90° Indiana days.

Heat Pump Replacement

Heat pumps move heat in and out of your home, depending on the season. Over time, coils, compressors, and controls wear out—especially with year-round use. If yours no longer heats well in winter or cools efficiently in summer, it may be time for a heat pump replacement. We install high-performance options, including hybrid models that pair with a gas furnace for added versatility when it gets really cold.

Geothermal System Replacement

Geothermal systems pull heat from the ground for ultra-efficient indoor comfort. While the underground loops can last decades, indoor components like the heat pump or blower motor usually need replacing around the 20-year mark. For a geothermal system replacement, we assess your existing setup and upgrade the indoor unit to restore quiet, consistent, and eco-friendly performance.

Ductless Mini Split Replacement

Ductless mini splits provide zoned heating and cooling with no ductwork required. But if your indoor units aren’t responding, the system runs loudly, or you’ve noticed uneven temperatures, it could be time for a ductless mini split replacement. We’ll help you choose smart, efficient new equipment and set up each zone for the control and comfort you need.

Whether you’re replacing your current equipment with something familiar or exploring a new approach, Thiele Heating & Air Conditioning will help you make the right call for your home, comfort, and budget.

Indoor Air Quality Replacement Services

Your HVAC system keeps the temperature comfortable, but indoor air quality systems handle everything else you can’t always see—dust, humidity, dryness, and airborne particles that affect how your home actually feels. These systems run quietly in the background, but when they stop working well, you need something new. At Thiele Heating & Air Conditioning, we offer indoor air quality replacement services so your whole system works together for cleaner, healthier air.

Air Cleaner Replacement

Air cleaners trap dust, pet dander, and allergens as air flows through your system. Over time, filters clog or internal parts wear out, reducing airflow and performance. A replacement unit helps your HVAC system breathe and your home feel fresher.

Air Purifier Replacement

Air purifiers use filtration or ionization to neutralize pollutants and microscopic irritants. If yours is no longer improving air quality or making a difference, it may not be operating at full strength. A new air purifier restores clean, balanced air in every room.

Dehumidifier Replacement

Dehumidifiers pull moisture from the air to prevent mold and that damp, musty smell. If humidity keeps creeping up or your system runs nonstop, it could be past its prime. A modern unit improves comfort and protects your home from moisture damage.

Humidifier Replacement

Humidifiers add gentle moisture to dry indoor air—especially useful during Indiana’s dry winters. If your home feels overly dry or your skin and sinuses are irritated, it could be due to poor output or aging parts. Replacing it restores balanced indoor comfort.

Thermostat Replacement

Thermostats control how and when your system runs, and even small calibration issues can cause bigger problems. If your home feels off or temperatures fluctuate, an upgraded thermostat helps improve accuracy, efficiency, and control.

UV Light Replacement

UV lights help sterilize your HVAC system by breaking down bacteria, mold, and viruses inside the ductwork. As bulbs wear out, their ability to sanitize drops. Replacing them helps maintain cleaner air and protects your system from buildup.

If you don’t already have an indoor air quality system in place, we can help with that, too. During your HVAC replacement, it’s the perfect time to assess how your home handles air quality and install the right solutions while everything’s being updated. Our team will explain your options, answer questions, and recommend upgrades that make your home feel cleaner, fresher, and more comfortable year-round.
