Furnace Maintenance In snohomish and king counties


You maintain your car, so why not your furnace?
You’ve heard the old adage, “A stitch in time saves nine”. Well, so too with furnaces. Furnaces are operational machinery with moving parts. If not maintained, those moving parts will wear out a lot quicker, leading to system failure. Your furnace system represents one of your home’s most costly systems, so it makes sense to faithfully maintain it.
What Can Go Wrong With a Furnace? More Than You’d Think.
Unusual Noises
Banging, rattling, or squealing sounds could mean loose parts, a failing motor, or airflow issues.
Weak or Inconsistent Airflow
If some rooms feel colder than others, your furnace may have clogged filters, duct issues, or a failing blower motor.
Higher Energy Bills
A sudden increase in heating costs often means your furnace is working harder than usual due to inefficiency.
Short Cycling (Turning On and Off Frequently)
If your furnace turns on and off too often, it could be due to overheating, a clogged filter, or a faulty thermostat.
Strange Odors
A burning smell could indicate dust buildup, while a rotten egg smell may signal a gas leak—which requires emergency service.
Furnace Struggles to Maintain Temperature
If your home isn’t as warm as it should be, your furnace may need a tune-up, filter replacement, or thermostat adjustment.
Dust and Poor Air Quality
Excessive dust or worsening allergy symptoms could mean your furnace is not filtering air properly due to a dirty filter or duct issues.
Furnace Running Constantly
A furnace that runs non-stop may be struggling to reach the desired temperature due to a thermostat issue, airflow restriction, or aging components.
Furnace is Over 10-15 Years Old
Older furnaces require more frequent maintenance and may lose efficiency over time.

Still Got Questions? We’ve Got Answers
How often should I have my furnace serviced?
We recommend scheduling a professional furnace maintenance tune-up once a year, ideally before the heating season begins. This helps ensure your system is running efficiently and prevents unexpected breakdowns.
Can I perform furnace maintenance myself?
While you can change the air filter and ensure the area around your furnace is clear, it’s best to leave the more technical aspects of furnace maintenance—like cleaning components and checking gas connections—to a licensed professional.
How do I know if my furnace needs professional maintenance?
Signs that your furnace may need professional attention include unusual noises, frequent cycling on and off, weak airflow, rising energy bills, or inconsistent heating.
Why is furnace maintenance important?
Regular maintenance helps keep your furnace running efficiently, extends its lifespan, and reduces the risk of costly repairs. It also ensures your furnace operates safely, preventing potential issues like gas leaks or carbon monoxide buildup.
How can I improve the efficiency of my furnace?
To improve efficiency, keep your filters clean, ensure proper airflow, seal any leaks in ducts, and schedule annual tune-ups. Additionally, using a programmable thermostat can help reduce energy consumption.
How often should I replace my furnace filter?
It’s recommended to check and replace your furnace filter every 1-3 months, depending on the type of filter and usage. Dirty filters restrict airflow, reduce efficiency, and can cause your furnace to overheat.
Can a dirty furnace filter affect performance?
Yes, a clogged filter restricts airflow, causing your furnace to work harder and use more energy. It can also lead to overheating and potential system failure.
What should I do if my furnace is making strange noises?
Strange noises like banging, rattling, or squealing could indicate mechanical issues. It’s best to have a professional inspect your system to prevent further damage or safety concerns.
How long does a furnace typically last?
With regular maintenance, a furnace can last 15-20 years. However, as the system ages, it may become less efficient, and replacement may be necessary.
When should I replace my furnace?
If your furnace is over 15 years old and requires frequent repairs, or if it’s inefficient and causing high energy bills, it might be time to consider a replacement.
Can I prevent furnace breakdowns?
While no system is completely immune to failure, regular maintenance is the best way to minimize the risk of breakdowns. A well-maintained furnace is less likely to experience unexpected issues.
Does furnace maintenance affect my warranty?
Yes, many manufacturers require annual maintenance to maintain the warranty. Skipping maintenance could void your warranty, leaving you responsible for future repair costs.
What are the benefits of regular furnace maintenance?
- Improved efficiency and lower energy costs
- Fewer repairs and unexpected breakdowns
- Increased lifespan of your system
- Enhanced safety by checking for potential hazards like gas leaks or carbon monoxide buildup
