What to Expect from Our AC Replacement Services
In-Depth System Evaluation
We assess your current system, usage patterns, and building infrastructure to determine whether a full replacement or system upgrade is best.
Energy-Efficient Upgrades
Outdated AC units often waste energy and drive up costs. We replace them with premium, high-SEER systems that deliver greater comfort and long-term savings.
Seamless System Integration
Whether you’re switching from central air to a ductless setup or replacing a rooftop unit, our replacements are clean, code-compliant, and minimally disruptive.
Performance Testing & Fine-Tuning
We inspect and test every installation for proper airflow, thermostat calibration, and low-noise performance—ensuring your new system is optimized from day one.
Post-Replacement Maintenance Support
Your investment is protected with follow-up support, tune-ups, and customized maintenance plans for long-term system health.

Signs your system may be due for a replacement:
Frequent breakdowns or rising repair costs
Recurring system failures are often a sign of mechanical fatigue, failing components, or deeper inefficiencies in aging HVAC systems. If repair expenses begin to approach 30–50% of the cost of a new system, replacement is typically the more financially responsible option.
Your system is 10-15+ years old
Units manufactured before 2010 may still rely on R-22 refrigerant, which has been phased out due to environmental regulations. These systems are not only less efficient, but also costly and difficult to maintain as R-22 becomes scarce and unsupported.
Inconsistent cooling or humidity issues
Uneven temperatures and excess humidity often indicate poor airflow distribution, degraded ductwork, or an undersized or failing unit. These issues not only affect comfort but also contribute to indoor air quality problems and accelerated wear on the system.
Loud operation, odd smells, or visible wear
Unusual noises, burning odors, or corrosion around the unit often signal internal deterioration—such as failing bearings, compromised insulation, or electrical issues. These signs indicate the system is operating under stress and may be at risk of a complete breakdown.
High energy bills
A noticeable spike in utility costs—especially without any change in usage—suggests the system is losing efficiency. Older units operate with lower SEER ratings and outdated compressor technology, leading to higher energy consumption and reduced performance.

Choosing the Right System
At Imperium, we don’t just swap out units—we guide you through the decision-making process to ensure your new system meets your needs.
Central Air Conditioning
Modern central AC systems offer significant improvements in noise reduction, zoning, and efficiency—ideal for traditional multi-unit properties.
Ductless Mini-Splits
A smart replacement for properties with aging or limited ductwork. Ductless systems provide room-by-room control and enhanced energy savings
Heat Pumps
For all-electric buildings or those transitioning away from gas, heat pumps provide year-round comfort with a lower environmental impact.
