Tip
If you’re facing one or more of the following issues, [installing/replacing/repairing] your [system] may be the most cost-effective solution.

Older units lose efficiency, break down frequently, and may not meet current energy standards.

Weak cooling performance often means the compressor or coil is deteriorating.

If repairs exceed 30% of the cost of replacement, installation is usually the better long-term choice.

A package unit handles both, reducing maintenance and maximizing reliability.

Pro Tip:
Replacing an aged package unit early often pays for itself with lower energy bills and improved cooling performance during heat waves.
Heater Repair Service Description
Rooftop package units are one of the most efficient and space-saving HVAC solutions for homes and commercial buildings in Sacramento. These units combine heating, cooling, blower functions, and controls in a single outdoor system placed on the roof. With no indoor furnace or air handler required, package units deliver powerful performance with minimal indoor footprint.
Many rooftop units experience performance decline due to weather exposure, long runtime hours, and heat stress. If your system frequently cycles during hot afternoons, produces weak airflow, or struggles to maintain temperature, these signs often indicate aging components.
Loud noises, such as rattling, humming, or fan squealing, typically point to failing motors or worn bearings. Excessive vibration can damage internal parts and reduce system lifespan.
A sudden increase in energy use is another key indicator. As rooftop units age, coil efficiency drops, requiring more electricity to deliver the same cooling output.
• Old or failing compressor
• Sun-damaged components reducing efficiency
• Frequent breakdowns during high-usage seasons
• High utility bills from inefficient operation
• Refrigerant leaks or outdated refrigerant
• Replacement parts becoming harder to find
• Poor airflow or uneven cooling
• Noise and vibration issues
Sacramento's long summers and warm shoulder seasons make rooftop systems ideal. Because they sit outdoors, they don’t consume indoor space and can deliver strong airflow across large areas. Their all-in-one heating and cooling design handles both summer heat and mild winter conditions efficiently.
High-performance rooftop units also help reduce environmental load by using advanced refrigerants and optimized energy consumption—factors especially relevant in Sacramento’s high-temperature months.
Repair is a good option when your rooftop unit is under 10 years old, needs minor component fixes, or functions well outside of a few isolated issues.
Replacement becomes smarter when:
• The unit is 12–20+ years old
• Repair costs exceed 25–30% of new installation
• Energy bills increase significantly
• Cooling output is weak in summer
• Core components like compressors or coils fail
Cronus Service handles the entire installation process—from roof assessment and equipment sizing to crane coordination and full system testing. Our technicians follow strict safety and code standards, ensuring your new package unit delivers optimal forced-air distribution, strong cooling performance, and reliable year-round operation.
Whether you’re replacing an aging rooftop unit or upgrading to a more efficient system, our licensed HVAC team ensures safe installation, accurate sizing, and long-term performance. Modern package units deliver powerful cooling, efficient heating, and reduced maintenance—ideal for Sacramento’s climate.
Serving Sacramento, Roseville, Rocklin, Lincoln, Granite Bay, Folsom, El Dorado Hills, Elk Grove, and nearby areas.
