Struggling with allergies, asthma, or poor air quality at home is a frustrating reality for many homeowners facing the humid continental climate of Elizabeth, IN.

All services are performed by licensed professionals with comprehensive warranties for peace of mind. Allegiance Heating & Air, LLC. understands that your home should be a sanctuary, not a source of respiratory distress.
Indoor Air Quality (IAQ) is not a single product but a comprehensive approach to managing the environment within your home. The air inside a modern, tightly sealed home can be up to five times more polluted than the air outside. Our services break down these pollutants into manageable categories: particulates, biological growth, and volatile organic compounds (VOCs). By addressing each category with specific hardware and strategies, we transform the breathability of your living space.
Standard one-inch furnace filters are designed primarily to protect the HVAC equipment, not the people breathing the air. We install media air cleaners and high-efficiency filtration cabinets directly into your ductwork.

Biological contaminants thrive in the dark, damp environment of an HVAC system, particularly on the cooling coils. Ultraviolet (UV) light technology neutralizes these threats at the cellular level.
In Elizabeth, managing moisture is half the battle. High humidity promotes mold growth, while low humidity in winter dries out sinuses and cracks wood furniture. We provide whole-home humidification and dehumidification solutions.
Modern homes are built airtight for energy efficiency, which unfortunately traps stale air inside. Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) swap stale indoor air for fresh outdoor air without losing energy.
Improving the air you breathe requires a systematic approach to identify the specific pollutants present and the best methods to remove them. We do not believe in one-size-fits-all guesswork. Our technicians follow a strict protocol to ensure the equipment installed delivers measurable results.
The process begins with a thorough evaluation of your current HVAC system and the air circulating through it. Technicians examine the ductwork for leaks that may be pulling in dust from attics or crawlspaces. We assess humidity levels and look for physical signs of mold or biological growth. If necessary, specific air testing can identify the concentration of VOCs or particulate matter.
Once the data is collected, we design a strategy that fits your specific home configuration. This may involve selecting a filter with the correct MERV rating that cleans the air without strangling the airflow of your specific furnace model. We determine the optimal placement for UV lights—usually above the coil—and size humidifiers based on the square footage and insulation quality of the home.
Installation involves cutting into the existing plenum or return drop to integrate the new equipment seamlessly. Technicians wire the IAQ components into the main HVAC control board. This ensures that accessories like humidifiers or air purifiers only run when the blower fan is active, maximizing efficiency and preventing waste.
After installation, the equipment is tested and calibrated. For humidifiers, this means setting the humidistat to the correct level for the current outdoor temperature. For ventilation systems, we balance the intake and exhaust airflow. We verify that static pressure within the ductwork remains within manufacturer specifications to ensure the longevity of your blower motor.
Finally, we walk you through the operation of your new system. You will learn how to change specialized media filters, when to replace UV bulbs (typically annually or bi-annually), and how to adjust settings based on seasonal changes.
Homeowners often wonder if they should invest in add-on air quality products or if they need to replace their entire HVAC system to solve air issues. This decision depends on the age of your current equipment, the condition of your ductwork, and the severity of the air quality problems.
If your heating and cooling system is less than 10 years old and functions mechanically well, adding IAQ peripherals is usually the most cost-effective path.
Sometimes, the source of the poor air quality is the HVAC unit itself or the duct system is too compromised for add-ons to be effective.
Regardless of whether you repair or replace the unit, the ductwork is the delivery system for your air. Leaky ducts in an attic or crawlspace can suck in fiberglass, mold spores, and insulation dust. Sealing or replacing damaged ducts is often a prerequisite for any high-efficiency air cleaner to work correctly. If the return, air ducts are pulling in dirty air from unconditioned spaces, a fancy filter at the furnace will clog rapidly and fail to solve the root problem.
The environment in Elizabeth, IN, dictates specific requirements for indoor air quality control. The humid continental climate presents a dual challenge: excessive moisture in the summer and bone-dry air in the winter. Equipment that works well in an arid climate may fail to perform here, and generic solutions often fall short.
In our region, summer dew points often remain high for weeks. High indoor humidity creates the perfect breeding ground for dust mites and mold. A standard air conditioner cools the air but may not run long enough to dehumidify it effectively on days with moderate temperatures but high humidity.
Conversely, winter brings air that holds very little moisture. When this air is heated by a furnace, the relative humidity drops drastically, often below 20%. This damages hardwood floors, causes static electricity, and dries out mucous membranes, making residents more susceptible to winter viruses.
All installations adhere to local building codes and safety regulations applicable to Elizabeth.
Selecting a contractor for indoor air quality is different from choosing someone for a simple repair. It requires a deep understanding of airflow dynamics, psychrometrics (the study of air and moisture), and microbiology. Our team does not just sell products; we engineer solutions that integrate with your home's existing infrastructure.
We use industrial-grade diagnostic tools to measure airflow and particle counts. This allows us to prove the effectiveness of the system before and after installation. We do not rely on guesswork; we rely on data.
We look at the house as a system. We understand that tightening up a home to save energy can have adverse effects on air quality if ventilation is not addressed. Our solutions balance energy efficiency with health and safety.
The market is flooded with "air purifiers" that make big claims but deliver little value. We only install contractor-grade equipment from reputable manufacturers with proven track records. We avoid unproven technologies that generate harmful byproducts like ozone.
Our technicians are fully vetted, background-checked, and trained in the latest IAQ technologies. We carry full insurance to protect your property during installation.
IAQ systems require maintenance to remain effective. We provide clear maintenance schedules and offer service plans to ensure your filters are changed, UV bulbs are replaced, and humidifiers are cleaned regularly.
When you trust Allegiance Heating & Air, LLC. with your indoor air quality, you are investing in the long-term health of your home and family. We remove the invisible threats in your air so you can breathe easier.
