We inspect burners, heat exchangers, ignition systems, electrical components, and airflow pathways to ensure safe operation.
Book request
Stage 2
Dust and buildup reduce heating output and efficiency. We clean burners, blowers, sensors, and coils for optimal performance.

Stage 3
We evaluate heating output, temperature rise, refrigerant balance (for heat pumps), and duct airflow.

Stage 4
We verify accurate thermostat operation, voltage balance, and proper communication between controls and heating components.

Stage 5
We provide improvements, safety findings, and recommended next steps to keep your system reliable all winter.

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

Maintenance restores airflow and ensures burners and coils operate efficiently.

A tuned system uses less energy and reduces strain on motors and compressors.

Cleaning and calibration prevent unnecessary wear and improve reliability.

Maintenance helps identify airflow issues, duct problems, or zoning imbalances.

Pro Tip:
Dust buildup, failing sensors, and clogged filters make the system work harder and shorten its lifespan. A professional tune-up not only improves heating efficiency but also prevents carbon monoxide risks, ignition failures, and expensive emergency repairs.
Heater Maintenance Service Description
Sacramento homes rely heavily on their heating systems during early mornings and cold winter nights. Regular maintenance ensures your furnace or heat pump operates safely, maintains proper airflow, and delivers consistent warmth without wasting energy. Annual maintenance also extends equipment lifespan and helps prevent sudden failures during the coldest days.
Your system may need professional service if it begins producing uneven temperatures, takes longer to heat rooms, or cycles more frequently. Strange noises such as rattling, whistling, or buzzing indicate mechanical or airflow issues. A burning smell or dusty odor usually means internal components need cleaning.
If your system struggles to turn on, overheats, or trips the breaker, it’s a sign that electrical components need inspection.
• Clogged burners and heat exchangers
• Dirty or failing blower motors
• Airflow restrictions from dirty ducts or filters
• Weak ignition or pilot failure
• Carbon monoxide risks from cracked exchangers
• Frozen heat pump coils
• Electrical shorts or worn wiring
• High energy usage from poor efficiency
Sacramento’s climate creates significant temperature swings throughout the winter. These fluctuations can stress heating systems and expose underlying problems. A well-maintained furnace or heat pump warms rooms faster, uses less energy, and handles winter mornings with ease.
Maintenance also helps identify minor issues before they cause winter breakdowns — saving money on repairs.
Maintenance is ideal when:
• Your system is working but seems less efficient
• You want to prevent breakdowns
• You moved into a new home and want safety confirmation
• It’s been more than 1 year since last tune-up
Repair may be needed if:
• System fails to heat
• Furnace short cycles or overheats
• Heat pump blows cold air
• Electrical components fail
During maintenance, if we find issues, we often complete the repair the same day in most cases.
Our maintenance process includes complete furnace or heat pump cleaning, electrical testing, safety checks, airflow measurement, and performance optimization. We ensure your system is ready for winter and operating at peak efficiency. If repairs are needed, our technicians carry most parts for same-day service in most cases.
Whether you have a furnace, heat pump, rooftop unit, or ductless system, Cronus Service provides reliable annual heating tune-ups tailored to Sacramento homes. Maintain comfort, reduce energy costs, and extend your system’s lifespan with our professional maintenance service.

FAQ
Most homes require annual maintenance before winter to ensure safe and efficient operation. Systems in dusty areas or older homes may need more frequent checkups. Regular maintenance prevents unexpected failures, extends equipment life, and keeps energy bills low. Skipping inspections increases wear and can lead to expensive mid-season breakdowns.
Strange noises often indicate dirty blowers, loose components, failing motors, or airflow restrictions. Whistling may come from duct leaks or clogged filters, while clicking or buzzing can come from electrical parts. A maintenance visit includes checking all moving parts and securing everything to prevent noise and damage.
Yes — most heating failures are caused by issues that could have been detected during a tune-up. Dirty coils, clogged burners, failing capacitors, and worn sensors often show early warning signs. By addressing these issues proactively, maintenance prevents major component failures and costly repairs. It also ensures safe operation during winter.
Absolutely. Clean burners, clean coils, proper lubrication, correct airflow, and accurate thermostat operation all reduce energy waste. A poorly maintained heating system works harder and uses more electricity or gas. Regular tune-ups help your system heat the home faster and more efficiently.
Yes — in most cases. Our technicians carry common heating system parts such as ignitors, sensors, capacitors, motors, and thermostats. If the issue involves specialized components, we can usually source parts the same day or next morning from local suppliers. We ensure your system is safe and stable while waiting for parts.
Yes. Furnaces require burner cleaning, ignition testing, gas safety checks, and heat exchanger inspection. Heat pumps require refrigerant balance checks, defrost cycle testing, coil cleaning, and airflow measurement. Cronus Service technicians are trained to maintain both systems to manufacturer standards.
