Heating and Air Conditioning Replacement Services

Every home is different, and your HVAC system should be tailored to how you live. Thiele Heating & Air Conditioning offers HVAC replacement services in Fishers for all system types, whether we originally installed them or not.

Furnace Replacement

When winter hits Central Indiana, your furnace needs to be ready. If your current system can’t keep up, we can install a new high-efficiency gas or electric furnace that delivers consistent warmth and lower monthly heating costs. We replace single-stage, two-stage, and variable-speed models to match your comfort and energy-saving goals.

Central Air Conditioner Replacement

If your central air conditioning unit is over a decade old, struggles to cool evenly, or has required frequent repairs, it’s likely time for a replacement. We’ll help you select a properly sized, energy-efficient AC system that improves indoor comfort, reduces humidity, and runs quietly—even on the hottest summer days.

Heat Pump Replacement

Whether you have a traditional air-source heat pump or a dual-fuel hybrid model, we’ll upgrade your outdated system with a new, energy-saving heat pump designed for year-round performance. Heat pump technology has come a long way, offering better temperature control, improved cold-weather performance, and greater energy savings.

Geothermal System Replacement

If your geothermal system’s indoor components—like the heat pump or air handler—are aging or underperforming, we can help. Our team will inspect your existing loop system and replace worn-out equipment with the latest geothermal HVAC solutions, bringing your ultra-efficient heating and cooling setup back to full strength.

Ductless Mini Split Replacement

Is your mini split no longer cooling or heating like it used to? New ductless mini split systems offer improved energy efficiency, quieter operation, and smarter temperature zoning. We’ll replace one or more indoor units or update the entire ductless system for better performance and comfort—no ductwork required.

Getting a new HVAC system opens the door to better efficiency, comfort, and features. Thiele Heating & Air Conditioning is here to match you with the ideal system for your home and budget.

Indoor Air Quality Replacement Services

We love seeing more and more homeowners in Fishers, IN, prioritize comfort and clean air by investing in indoor air quality systems. Whether it’s a whole-home humidifier, air purifier, or UV light setup, these additions make a big difference in how your home feels and functions. But like any part of your HVAC system, they need to be updated over time to keep working their best.

Air Cleaner Replacement

Is your home dustier than usual, even with regular cleaning? An older air cleaner could be the culprit. We’ll install a high-efficiency air cleaner that captures airborne particles more effectively.

Air Purifier Replacement

When indoor air feels stale or stuffy, your air purifier may need replacing. Modern systems target more pollutants and improve air circulation throughout your home.

Dehumidifier Replacement

Tired of musty smells or that clammy feeling indoors? An older dehumidifier may be falling behind. A new system helps manage humidity more efficiently and protects your air quality.

Humidifier Replacement

If your skin, sinuses, and wood furnishings are suffering during Indiana winters, your humidifier might not be working as it should. We’ll replace it with a more reliable whole-home system.

Thermostat Replacement

A thermostat that’s off by even a few degrees can waste energy and hurt comfort. We’ll help you switch to a smart model that integrates seamlessly with your new HVAC system.

UV Light Replacement

UV lights help clean the air by killing mold, bacteria, and viruses inside your HVAC system. When the bulb weakens over time, we’ll replace it to keep your air cleaner and healthier.

If you haven’t added air quality upgrades to your HVAC system yet, now’s a great time. We’ll help you choose the right options to improve airflow, reduce allergens, and create a cleaner, more comfortable home.
