AC installation and repair in Kirkland, explained in 30 seconds
Green House Plumbing and Heating installs, repairs and maintains central air conditioners, heat pumps and ductless mini-splits for Kirkland homes. We are based at 12040 98th Ave NE in Kirkland (98034), work Monday to Saturday from 7 am to 9 pm, and offer same-day appointments when available.
Many Eastside homes were built without air conditioning. That changed fast after the June 2021 heat dome, when Seattle hit an all-time record of 108°F. Today most Kirkland homeowners choose between a central AC or heat pump on existing ducts, or a ductless mini-split for homes with baseboard heat or a hot upstairs.
We size the system to your home, explain the options in plain language, handle the permit, and give you an upfront price.
AC stopped cooling on a hot day? Check this first
These quick checks solve a surprising number of no-cool calls. If they do not, call us.
- Check the thermostat. Set it to Cool, a few degrees below room temperature, and replace the batteries if the screen is blank.
- Check the breakers. Look for a tripped breaker for the outdoor unit and the furnace or air handler.
- Look at the air filter. A clogged filter can freeze the coil and stop airflow. Replace it if it looks gray.
- See if ice is forming. Ice on the lines or coil? Turn cooling off and run the fan only, then call us.
- Keep the home cool. Close blinds on sunny sides and run fans until we arrive.
AC problems we fix in Kirkland homes
Match what you see to the likely cause and how we fix it.
AC runs but blows warm air
- Likely cause
- Low refrigerant from a leak, a failed capacitor or a dirty outdoor coil.
- How we fix it
- We test pressures and electrical parts, fix the cause and recharge only after the leak is repaired.
Outdoor unit will not start
- Likely cause
- Failed capacitor or contactor, tripped breaker or a thermostat problem.
- How we fix it
- We test and replace the failed part, often on the first visit.
Weak airflow or hot upstairs rooms
- Likely cause
- Dirty filter, closed or leaky ducts, or a system sized for the downstairs only.
- How we fix it
- We check airflow and ducts, and suggest a ductless head for rooms that stay hot.
Ice on the lines or indoor coil
- Likely cause
- Low airflow from a clogged filter, or low refrigerant.
- How we fix it
- We thaw the coil, fix the airflow or leak and confirm proper operation.
Water leaking near the furnace
- Likely cause
- Clogged condensate drain or a cracked drain pan.
- How we fix it
- We clear the drain line, replace the pan if needed and check the safety switch.
Ductless unit blinking or not cooling
- Likely cause
- Error code from a sensor, a dirty filter or coil, or a drain problem.
- How we fix it
- We read the error code, clean the head and coil and repair the fault.
Repair or replace your air conditioner?
We give you both options with prices, and tell you which one we would choose in your home.
Repair usually makes sense when
- A capacitor, contactor or fan motor failed
- The system is under about 10 years old
- The leak is small and easy to reach
- It cooled well until recently
Replacement usually makes sense when
- The system is 12 to 15 years old or more
- The compressor failed outside warranty
- Repairs keep coming back every summer
- You want heating and cooling from one efficient heat pump
| System | Best for | Notes |
|---|---|---|
| Central AC | Homes with a gas furnace and good ducts | Cools only, pairs with your furnace |
| Ducted heat pump | Homes with ducts that want efficient heat and AC | One system for year-round comfort |
| Ductless mini-split | Baseboard heat, additions, hot upstairs rooms | No ducts needed, room-by-room control |
| Portable or window unit | Short-term relief | Low cost, noisy, cools one room |

What Kirkland homeowners should know about air conditioning
Our climate is mild most of the year, then very hot for a few weeks.
Heat waves are getting more common
Seattle reached 108°F on June 28, 2021. As of 2019, only about 44 percent of Seattle homes had air conditioning, which is why so many Eastside homes are adding it now.
Heat pumps fit our climate
Kirkland winters are mild, so a heat pump can cover most of the year's heating as well as summer cooling. Many homeowners pair one with an existing gas furnace as backup.
Hot upstairs, cool downstairs
Older Kirkland homes in neighborhoods like Norkirk, Market and Houghton often have bedrooms that stay hot. A ductless head upstairs is often simpler than rebuilding ducts.
Service before the first warm week
Book maintenance in spring. Repair calls spike in the first hot week of summer, when parts and appointments are hardest to get.

Do I need a permit to install AC in Kirkland?
Usually, yes. Kirkland requires a mechanical permit when mechanical systems are installed or replaced, and new outdoor units often need electrical work as well. We confirm what your job needs and handle the permits.
Should I get central AC, a heat pump or a ductless mini-split?
If you have good ducts and a gas furnace, central AC or a ducted heat pump works well. If you have baseboard heat or a hot upstairs, a ductless mini-split is usually simpler. A heat pump also heats efficiently in Kirkland's mild winters.
Why is my AC running but not cooling?
The most common causes are a clogged filter, a dirty outdoor coil, a failed capacitor or low refrigerant from a leak. Check the filter and breakers first, then call us if it still blows warm air.
How often should I service my air conditioner?
Once a year, ideally in spring before the first heat. Change or clean the filter every one to three months while the system is in use.
How long does an AC or heat pump last?
Many systems last around 12 to 15 years with regular maintenance. Ductless systems and heat pumps that run year-round may need parts sooner.
Can you still repair older R-410A systems?
Yes. New systems use lower-impact refrigerants such as R-454B or R-32, but existing R-410A systems can still be serviced and repaired.
How long does AC installation take?
Most central AC or heat pump replacements take one to two days. A single-zone ductless mini-split often takes one day.
Which areas near Kirkland do you serve?
All Kirkland neighborhoods, including Juanita, Finn Hill, Kingsgate, Totem Lake, Rose Hill, Houghton and Bridle Trails, plus Bellevue, Redmond, Bothell, Woodinville and Kenmore.
