Tip
If you’re facing one or more of the following issues, repairing your heater may be the most cost-effective solution.

Often caused by worn ignitors, weak burners, clogged filters, or electrical issues that are quickly repairable.
Rattling, burning odor, or whistling noises often indicate simple mechanical failures or airflow restrictions.
This frequently occurs due to sensor faults, dirty components, or blocked airflow — all repairable issues.
A malfunctioning heater consumes more energy; restoring proper function usually solves the issue.
Pro Tip:
Instead of repeated repairs, replacement can often pay for itself through lower bills, improved comfort, and fewer surprises.
Heater Repair Service Description
When winter temperatures drop in Sacramento area, a malfunctioning heater can make your home uncomfortable and increase monthly energy bills. Timely heater repair prevents emergency failures, improves efficiency, and helps your system maintain steady performance during cold mornings and chilly nights.
Homeowners often notice performance issues long before the heater fully fails. Reduced heat output, longer run times, or cold spots throughout the home frequently indicate ignition or airflow problems. These issues usually worsen over time if not corrected.
Unusual smells — especially burning or metallic odors — often come from dirty burners, overheating components, or worn electrical connections. These should be addressed immediately for safety.
Irregular cycling or short bursts of heat followed by shutdowns often signal a failing sensor or overheating problem. Early intervention prevents major damage.
• Faulty ignitors and flame sensors
• Dirty or misaligned burners
• Weak blower motors
• Overheating and safety shutoffs
• Thermostat communication issues
• Airflow restrictions and clogged filters
• Excessive noise or vibration
• Electrical control failures
• Inconsistent or weak heating
Sacramento’s winters are mild compared to colder states, but nighttime temperatures regularly drop into the 30s. A failing heater not only reduces comfort but also drives up energy use as the system struggles to maintain temperature. Repairing issues early keeps heating costs predictable and prevents unnecessary strain on aging equipment.
Repair usually makes the most sense for heaters under 10 years old or when the issue involves minor components like sensors, ignitors, or relays. These repairs are affordable and restore performance quickly.
Replacement becomes the better investment when:
• The system is 12–15+ years old
• Repairs exceed 30% of the cost of replacement
• Energy bills have increased noticeably
• The system experiences frequent shutdowns
• The equipment is outdated or uses old technology

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!
Denys added extended ductwork to a room that didn't have central unit hooked up! But now it's up and running!! Awesome job for only one man to do the project!!! Hopefully will last awhile! No more TOO HOT or TOO COLD in the room! JUST RIGHT!!!DENYS IS DA MAN!!!Thanks Denys!!!
