When you choose Allegiance Heating & Air, LLC. for your cooling needs, you secure the following outcomes:
Investing in a new air conditioning system is more than just swapping out a box outside your home; it is a comprehensive construction project that alters how your home manages energy and comfort. Modern cooling systems are significantly more advanced than units manufactured even a decade ago. Consequently, the installation process requires a high level of technical precision to ensure the equipment achieves its rated efficiency.
When you move forward with a new installation in Charlestown, the focus shifts immediately to accurate sizing and system selection. A unit that is too large will cycle on and off frequently, leading to wear and tear, while a unit that is too small will run continuously without ever cooling the space adequately. We utilize industry-standard Manual J load calculations to determine the exact cooling requirements of your home. This calculation considers square footage, insulation levels, window placement, and local climate data to prescribe the perfect system size.
Current SEER2 (Seasonal Energy Efficiency Ratio) standards require higher efficiency levels, which translates to lower monthly utility bills for homeowners. You can expect access to various system configurations, including single-stage, two-stage, and variable-speed compressors. Single-stage units operate at 100% capacity when on, whereas variable-speed units adjust their output incrementally to maintain precise temperatures and superior humidity control. This selection phase is critical, as it determines your comfort level and energy expenditure for the next 15 to 20 years.

A professional installation follows a rigorous, standardized procedure to ensure safety, efficiency, and longevity. We do not skip steps or cut corners. From the moment the technicians arrive at your property, the workflow is designed to minimize disruption while maximizing system performance.
Determining whether to repair a failing unit or invest in a replacement is a major financial decision. While repairs can offer a short-term fix, there is a tipping point where continuing to patch up an old system becomes arguably more expensive than replacing it.
You should evaluate the age of your equipment first. The average lifespan of a central air conditioner is typically between 12 and 15 years. If your unit is approaching or has surpassed this range, major components like the compressor are likely nearing the end of their operational life. Investing heavily in a unit this old often results in throwing good money after bad.
Consider the "50% Rule" used by many industry experts. If the cost of the repair equals or exceeds 50% of the value of a new system, replacement is generally the wiser financial choice. For example, replacing a compressor out of warranty is a significant expense. When you factor in the energy savings of a new, high-efficiency system, the return on investment often favors replacement over a costly repair on an aging unit.
Refrigerant type is another critical factor. Older systems utilize R-22 (Freon), which has been phased out due to environmental regulations. Supplies of R-22 are limited and extremely expensive. If your older unit has a refrigerant leak, the cost to refill it may be prohibitive, and finding R-22 will only become more difficult. Modern systems use R-410A or newer, eco-friendly refrigerants like R-454B, which are readily available and more efficient.
Finally, assess your comfort and the frequency of breakdowns. If your system requires repairs every season, struggles to keep up on days exceeding 90°F, or fails to dehumidify your home effectively, it is failing to perform its primary function. A new installation eliminates these reliability issues and provides consistent comfort — schedule service today.
Operating an air conditioning system in Charlestown presents specific challenges due to the regional climate. We experience a significant variance in seasonal temperatures, from freezing winters to humid, hot summers where temperatures often climb into the upper 80s and low 90s. This fluctuation puts thermal stress on HVAC equipment. The high humidity levels in the Ohio Valley region mean that your AC unit must do more than just lower the temperature; it must also effectively remove moisture from the air to prevent mold growth and ensure the air feels cool rather than clammy.
Because of these demands, correct sizing is paramount. An undersized unit will run indefinitely during a July heatwave, driving up electric bills and failing to cool the house. Conversely, oversizing the unit to "be safe" results in short-cycling, where the unit cools the air too fast but shuts off before it can extract humidity, leading to a cold, damp indoor environment.
From a regulatory standpoint, replacing an air conditioning system involves adherence to Indiana state building codes and local municipal regulations. Permits are generally required for HVAC installations to ensure the safety of the electrical connections and the integrity of the installation.
We handle the logistical burden of permit applications and ensure that every aspect of the installation meets or exceeds the local code requirements for Charlestown and the surrounding county areas. This compliance is essential not only for safety but also for maintaining the validity of your home insurance and the manufacturer's warranty.
