This guide explains what to expect from our repair services, common issues we fix, our diagnostic approach, and how to decide between repair and replacement.

Why Timely HVAC Repair Matters for Issaquah Homes

Issaquah experiences cool, wet winters that place heavy demands on furnaces and heat pumps, while spring through fall may bring enough warmth and humidity to require reliable cooling. Neglecting HVAC issues can lead to:

  • Increased energy bills from inefficient operation
  • Poor indoor air quality from clogged filters or failing components
  • Inconsistent temperature and discomfort
  • Safety risks such as carbon monoxide leaks from faulty furnaces
  • More expensive breakdowns when minor faults escalate

Green Head Heating focuses on restoring safe, efficient operation quickly while providing homeowners with clear information for immediate fixes vs long-term solutions.

Common HVAC Problems in Issaquah

Understanding common faults helps homeowners identify issues early and describe symptoms accurately when scheduling service.

Furnace and Heating Problems

  • Furnace fails to start or cycles frequently
  • Weak or no heat output
  • Strange noises: banging, rattling, whistling
  • Pilot light or ignition issues in older gas furnaces
  • Blower motor failures or reduced airflow
  • Yellow or flickering pilot light (possible combustion issues)
  • Carbon monoxide alarm activation or suspected leaks

Air Conditioner and Heat Pump Problems

  • AC not cooling or slow to reach set temperature
  • Frozen evaporator coil or refrigerant leaks
  • Compressor failures or short cycling
  • Weak airflow or warm air blowing during cooling
  • Condenser fan or motor problems
  • Thermostat communication errors or calibration issues

Controls, Ventilation, and Indoor Air Quality

  • Thermostat not controlling system properly
  • Uneven temperatures between rooms
  • High humidity or persistent damp odors
  • Excessive dust or reduced airflow from clogged filters/ducts

Electrical and Safety Issues

  • Tripped breakers or blown fuses
  • Burnt wiring smells or visible scorch marks
  • Safety switch or limit control faults causing shutdowns

How We Diagnose HVAC Problems

Green Head Heating uses a systematic diagnostic process to ensure repairs address root causes:

  1. Initial Symptom Intake – Homeowner observations, system run-time, recent performance changes
  2. Visual and Safety Inspection – Check filters, ductwork, condensate drains, water damage, corrosion, and rodent activity. Verify carbon monoxide safety for gas systems
  3. Electrical and Control Checks – Voltage, amperage, thermostat settings, wire continuity, control signals
  4. Mechanical and Airflow Evaluation – Airflow measurement, blower wheels, belts, motor bearings, evaporator/condenser coil condition
  5. Refrigerant and Pressure Testing – For AC and heat pumps, gauge pressures and check for leaks
  6. System Operation Under Load – Observe heating/cooling cycle performance, noises, and abnormal behaviors
  7. Clear Findings and Recommendations – Plain-language explanation of root causes, repair options, outcomes, and transparent pricing

  • Line-item descriptions of parts and labor
  • Honest guidance for temporary vs permanent fixes
  • Documentation with diagnostic findings and photos

Same-Day Parts and Return Visits

Minimizing downtime is critical in Issaquah winters:

  • Same-day parts for common items (capacitors, thermostats, ignitors, fan motors)
  • Expedited sourcing for manufacturer-specific parts
  • Documented return visits for staged repairs or warranty work
  • Follow-up verification runs after parts replacement

Examples of Typical Fixes

Example 1: Furnace Short Cycling

  • Symptom: Furnace runs 3–5 minutes, then shuts off
  • Diagnosis: Dirty flame sensor + slightly clogged filter
  • Repair: Clean/test sensor, replace filter
  • Outcome: Normal furnace cycles, improved comfort, avoids blower stress

Example 2: AC Blowing Warm Air

  • Symptom: AC compressor not engaging
  • Diagnosis: Failed start capacitor + minor refrigerant leak
  • Repair: Replace capacitor, repair leak, recharge refrigerant
  • Outcome: Reliable cooling, leak resolved

Example 3: Heat Pump Not Heating

  • Symptom: House remains cold
  • Diagnosis: Faulty reversing valve solenoid + dirty outdoor coil
  • Repair: Replace solenoid, clean coil, verify defrost control
  • Outcome: Heat pump restored, efficient heating

Repair vs Replacement

Factors to consider:

  • Age of equipment: Units >12–15 years may be better replaced
  • Frequency and cost of repairs: Multiple major repairs in last 2 years favors replacement
  • Energy efficiency: Older units may have higher utility costs
  • Safety and reliability: Corrosion, cracked heat exchangers, or past combustion issues
  • Comfort and performance goals: Humidity control, zoning, quieter operation
  • Environmental considerations: New refrigerants, higher SEER ratings, incentives

Rule of Thumb: If repair exceeds 50% of a new unit’s cost and the system is past halfway of its expected life, replacement should be considered.

Maintenance and Prevention for Issaquah Homes

  • Fall Furnace Tune-Up: Clean burners, inspect ignition/heat exchanger, test safety controls
  • Spring AC/Heat Pump Service: Clean coils, verify refrigerant, inspect condensate drains
  • Monthly Filter Checks: Replace or clean every 1–3 months
  • Keep Outdoor Equipment Clear: Trim brush, remove debris
  • Control Humidity Proactively: Use kitchen/bath fans, proper ventilation
  • Monitor Early Warning Signs: Strange smells, noises, visible water, short cycling

Unique Challenges in Issaquah

  • Coastal moisture: Salt air accelerates corrosion; protective coatings and inspections are important
  • Seasonal swings: Heat pumps require careful defrost and reversing valve monitoring
  • Energy-conscious homeowners: Repairs often include efficiency improvements or incentive guidance

Warranty, Documentation, and Post-Repair Verification

  • Clear service reports detailing diagnostics, parts replaced, and operational checks
  • Warranty information for parts and labor
  • Recommendations for follow-up or next service intervals
  • Post-repair verification runs under load

Green Head Heating did the HVAC on our large new construction custom home. They have more than taken care of us from start to finish. Everything was VERY well thought out. They were knowledgable with energy credits, which is often times missed! This was a trade that was very important to us as it is inside your walls. I am certain we have the BEST system. They truly didn’t miss anything! Would highly recommend!

Brittany A.

Ryan has the exact experience to make sure you’re getting the climate control that your home needs. His knowledge is extensive and he always has an answer to every question and on top of that he’s pleasant to work with. Ryan and his main tech Tristan have done many high quality HVAC installs that I have seen in the last year and I couldn’t imagine trusting anyone else for the job. Thank you, Greenheads!

Karlan S.

We decided to replace our very old gas furnace with a newer and hopefully quieter furnace.  We contacted Greenhead because they were a smaller, local business.  Everything about the process was excellent.  Best of all the furnace is exceptionally quiet.  Thanks Greenhead.

Bruce R.

Would recommend! Our heat cut out during a cold snap - I called Greenhead the next morning and Ryan was at my house the same afternoon. He quickly diagnosed a faulty switch in our furnace and was back that evening with a new part! Pricing was reasonable, especially given the urgency.

Eamonn K.

I had Greenhead out to do service on my gas furnace and heat pump. Ryan was very professional and helpful. The service was very reasonably priced even though they were there in the evening! I would recommend them to anyone.

Lindsay P.

Came same day when we had no heat. Worked quickly to find the issue while explaining everything he was doing. Really took the time to make us feel like a valued customer not just a number. Also the pricing was very fair which in todays economy is always so helpful... we will be using this company for all future heating needs
