For homeowners in Sellersburg, achieving consistent, year-round comfort without breaking the bank on utility bills can feel like a constant challenge. You need a heating system that can handle Indiana’s cold winters and an air conditioner that can stand up to humid summers. A modern heat pump system offers a powerful, all-in-one solution, providing exceptional efficiency for both heating and cooling.
At Allegiance Heating & Air, LLC, we specialize in providing comprehensive heat pump installation, repair, and maintenance services, ensuring your home remains a sanctuary of comfort no matter the season. We are dedicated to delivering expert solutions and unparalleled workmanship, taking your home’s comfort under our wing.
Unlike traditional furnaces that burn fuel to create heat or air conditioners that only cool, a heat pump operates on a principle of heat transfer. This innovative technology uses a refrigerant cycle to move heat from one place to another.
In the summer, it functions just like a standard air conditioner. The indoor unit absorbs heat from your home’s air and transfers it outside, leaving your indoor space cool and comfortable.
In the winter, the process reverses. Even when it feels cold outside, there is still ambient heat energy in the air. The outdoor unit extracts this heat and transfers it inside your home, providing efficient and consistent warmth. This process of moving heat rather than generating it is what makes heat pumps one of the most energy-efficient HVAC solutions available today.

Choosing the right system depends on your home’s layout, your energy goals, and your existing infrastructure. We provide expert guidance on the best type of heat pump to meet your specific needs.
From initial installation to emergency repairs and routine upkeep, our factory-trained technicians have the expertise to handle every aspect of your heat pump’s lifecycle.
A heat pump’s performance and lifespan are directly tied to the quality of its installation. An improperly sized or installed unit will struggle to keep your home comfortable, run inefficiently, and be prone to premature failure.
Our meticulous installation process ensures your new system is set up for optimal performance from day one. We handle everything, from helping you select the right high-efficiency model to carefully integrating it with your home’s existing infrastructure. If you have an aging furnace and air conditioner, replacing both with a single, high-efficiency heat pump is a smart investment in your home’s comfort and value.
When your heat pump stops working correctly, you need fast, dependable service. Our technicians are equipped to diagnose and resolve any issue, from minor electrical faults to complex compressor problems.
Look for common signs that your system needs professional attention:
We respond promptly to restore your comfort, ensuring your system is repaired correctly and safely.
Regular maintenance is the single most important factor in maximizing your heat pump's efficiency, preventing unexpected breakdowns, and extending its service life.
Because your heat pump works all year long, we recommend a professional tune-up twice a year—once in the spring to prepare for cooling season and once in the fall to prepare for heating season. During a maintenance visit, our technicians will clean coils, inspect electrical connections, check refrigerant levels, lubricate moving parts, and ensure the entire system is operating at peak performance.
You can also explore our maintenance plan options to keep your system running smoothly while enjoying priority service and special discounts.
A professionally installed and well-maintained heat pump can provide you with year-round comfort, improved energy efficiency, and reduced heating and cooling costs. Whether you need expert installation, fast repairs, or a comprehensive maintenance plan, our team at Allegiance Heating & Air is here to help you get the most out of your HVAC system.
Absolutely. Modern heat pump technology has advanced significantly. Today’s high-efficiency models can effectively heat a home even when outdoor temperatures drop near freezing. For the coldest days of winter, they are often paired with an auxiliary heat source, such as electric resistance heat strips or a backup furnace, to ensure your home stays warm without interruption.
With proper installation and consistent professional maintenance, a typical air-source heat pump can last 15 years or more. Geothermal systems have an even longer lifespan, with underground components lasting for decades.
The primary benefits are superior energy efficiency and lower utility costs. Because they move heat rather than generate it, they can deliver up to three times more heat energy than the electrical energy they consume. They also provide the convenience of heating and cooling in a single unit and can improve indoor air quality by providing excellent dehumidification during the summer.
