Tip

When Installing a Rooftop Package Unit Is the Smart Choice

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

(01)

Your existing rooftop unit is 12–20+ years old

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

(02)

Your system struggles during Sacramento’s hot summers

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

(03)

Repairs are becoming frequent and expensive

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

(04)

You want heating and cooling in one integrated system

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

Cronus Service - pro tip

Pro Tip:

Even if your rooftop unit “still runs,” heat exposure, vibration, and prolonged Sacramento summers can severely reduce efficiency over time.

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 Unit Installation in Sacramento — What Homeowners and Businesses Should Know

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.

How to Tell You Need a New Rooftop Package Unit

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.

Common Reasons Homeowners and Businesses Replace Rooftop Units

• 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

Why Rooftop Package Units Suit Sacramento’s Climate

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 Vs. Replacement — Which Is Better for Rooftop Units?

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

Into The D.

I requested quotes from five AC companies and most of them were overpriced- the highest was over $25k. There were others that were less. Cronus service came out the lowest, so I went with them. Sergei, Dennis, and Alex were very professional. They actually shook my hand and introduced themselves. It was a two day install, temps were hot but they kept on working and didn't stop until the install was completed. At the end of the day this company and the workers at top notch. You can trust them, no gimmicks or stings attached.

Highly recommend Cronus Service! AC unit was not working and was able to get a serviceman from Cronus Service for a same day FREE diagnostic. Other repair companies charged upwards of $200 just for the service.
Upon arrival (communication was very clear and crisp), Alex took a look at our system and diagnosed the issue right away. He took time to explain everything that was happening and what his recommended fixes were. The quoted cost was very fair and he had the parts ready in his truck to fix right away. Even included a free tune up!
