Heating Questions

Keeping your home warm and comfortable

Why is my furnace not producing heat?

There are several common reasons your furnace may not be producing heat. Before calling for service, check these items:

Thermostat settings: Ensure it's set to "heat" mode and the temperature is set above the current room temperature
Air filter: A severely clogged filter can restrict airflow enough to trigger safety shutoffs
Circuit breaker: Check that the furnace breaker hasn't tripped
Gas supply: Verify the gas valve near your furnace is in the "on" position
Pilot light or igniter: Older furnaces may have a pilot light that's gone out

If none of these resolve the issue, call us at (425) 648-7887. Issues like a faulty igniter, cracked heat exchanger, or malfunctioning control board require professional diagnosis and repair.

How long does a furnace typically last?

The average lifespan of a well-maintained furnace is 15 to 20 years, though some systems can last longer with proper care. Key factors that affect furnace longevity include:

Regular maintenance: Annual tune-ups can add years to your system's life
Filter changes: Consistent filter replacement prevents strain on components
Quality of installation: A properly sized and installed furnace performs better and lasts longer
Usage patterns: Homes in colder climates may see shorter lifespans due to heavier use

Signs it may be time to replace your furnace include frequent repairs, rising energy bills, uneven heating, unusual noises, and a system older than 15 years. We offer free replacement estimates to help you make an informed decision.

Why is my furnace making strange noises?

Different sounds can indicate different issues with your furnace:

Banging or popping: Often caused by delayed ignition or expanding/contracting ductwork as temperatures change
Squealing or screeching: Usually a worn blower motor belt or bearing that needs lubrication or replacement
Rattling: Could indicate loose panels, screws, or ductwork connections
Clicking: Repeated clicking during startup may signal a failing igniter or flame sensor
Rumbling: A low rumbling after the burners shut off can indicate a dirty burner or pilot light issue

While some noises are normal (gentle whooshing of air, soft clicking at startup), persistent or loud unusual sounds should be evaluated by a professional to prevent more costly repairs down the line.

Should I choose a gas or electric furnace?

The best choice depends on your home's infrastructure, budget, and priorities:

Gas furnaces heat quickly, are highly effective in cold weather, and typically have lower operating costs in areas with affordable natural gas
Electric furnaces have lower upfront costs, require no gas line, have fewer safety concerns, and are easier to install
Heat pumps are increasingly popular as an efficient electric alternative, providing both heating and cooling with excellent energy savings

In the Pacific Northwest, many homeowners are transitioning to heat pump systems for their dual functionality and efficiency. We'll help you evaluate your options based on your home's specific needs during a free consultation.

Why are some rooms colder than others?

Uneven heating is a common complaint with several potential causes:

Ductwork issues: Leaky, disconnected, or poorly insulated ducts can lose heat before it reaches distant rooms
Improper system sizing: An undersized furnace struggles to heat the entire home adequately
Blocked vents: Furniture, rugs, or closed registers can restrict airflow to certain rooms
Insulation gaps: Poorly insulated walls, attics, or crawl spaces allow heat to escape
Old windows: Single-pane or drafty windows cause significant heat loss in affected rooms

Our technicians can perform an airflow analysis to identify the root cause and recommend solutions, whether it's duct sealing, a zoning system, or supplemental heating for problem areas.

Cooling Questions

Beat the heat with expert AC solutions

Why isn't my AC blowing cold air?

If your air conditioner is running but not cooling, several issues could be at play:

Dirty air filter: A clogged filter restricts airflow over the evaporator coil, reducing cooling capacity
Thermostat settings: Ensure it's set to "cool" mode and the fan is set to "auto" rather than "on"
Frozen evaporator coil: Restricted airflow or low refrigerant can cause ice buildup on the coil
Low refrigerant: A refrigerant leak reduces your system's ability to absorb and remove heat
Dirty condenser coils: Outdoor unit coils clogged with debris can't release heat effectively

Start by checking and replacing your filter and clearing any debris around your outdoor unit. If the problem persists, call us at (425) 648-7887 for professional diagnosis.

What size AC do I need for my home?

Proper AC sizing is critical for comfort and efficiency. An oversized unit short-cycles (turns on and off frequently), wasting energy and failing to dehumidify. An undersized unit runs constantly without adequately cooling. Factors that determine the right size include:

Home square footage and layout (number of stories, open floor plan vs. compartmentalized)
Insulation quality in walls, attic, and crawl space
Window count and orientation (south/west-facing windows add significant heat gain)
Local climate and typical summer temperatures
Ductwork condition and existing infrastructure

We perform a Manual J load calculation during our free estimate to determine the precise cooling capacity your home needs. This scientific approach ensures you get the right-sized system for maximum comfort and efficiency.

How long should my air conditioner last?

A well-maintained central air conditioner typically lasts 12 to 17 years. Key signs that your AC may be nearing end of life include:

Frequent repairs: If repair costs are approaching 50% of replacement cost, it's time to upgrade
Rising energy bills: Declining efficiency means higher operating costs each summer
R-22 refrigerant: If your system uses R-22 (Freon), it's outdated and costly to service
Inconsistent cooling: Hot spots and humidity issues worsen as systems age
Excessive noise: Grinding, squealing, or rattling from worn components

Modern AC systems are significantly more efficient than units from even 10 years ago, with higher SEER2 ratings that can cut cooling costs by 20-40%. Contact us for a free replacement estimate.

What's the ideal thermostat setting for summer?

The U.S. Department of Energy recommends 78 degrees Fahrenheit when you're home and awake during summer. Here are some tips for maximizing comfort while minimizing costs:

When home: 78 degrees is the sweet spot for comfort and efficiency
When away: Raise the temperature 7-10 degrees while you're at work or out
While sleeping: Many people prefer slightly cooler at 75-77 degrees for better sleep
Use a programmable thermostat: Automate temperature changes based on your daily schedule

Each degree you raise the thermostat saves approximately 3% on cooling costs. A smart or programmable thermostat can save the average household $50-150 annually by automatically adjusting temperatures.

What are ductless mini-split systems?

Ductless mini-split systems consist of an outdoor compressor unit connected to one or more indoor air handlers. They're an excellent solution in many situations:

Homes without existing ductwork (older homes, additions, converted spaces)
Room additions or renovations where extending ductwork isn't practical
Zoned comfort: Each indoor unit can be controlled independently for personalized temperatures
Energy efficiency: No duct losses means more of the energy you pay for actually heats or cools your space
Quiet operation: Indoor units operate at whisper-quiet levels as low as 19 decibels

Most mini-splits are heat pumps, providing both heating and cooling year-round. Installation is minimally invasive, requiring only a small hole through the wall for the refrigerant line.

Heat Pump Questions

Efficient heating and cooling in one system

Do heat pumps work in Washington winters?

Yes! Modern heat pumps are engineered to work effectively in cold climates, and Washington's winters are well within their operating range. Today's cold-climate heat pumps can maintain efficient heating in temperatures as low as -15 to -20 degrees Fahrenheit.

The Pacific Northwest's relatively mild winters (averaging 35-45 degrees in the Covington area) make it one of the ideal regions for heat pump technology. Key advancements include:

Inverter-driven compressors that modulate output to match heating demands precisely
Enhanced vapor injection technology for improved low-temperature performance
