Seattle Heating and Air Conditioning Services
Kodiak Heating & Cooling is what we call the HVAC branch of our business. We know that Seattle winters can bring months of wet, chilly weather that puts continuous strain on your home heating system. We offer fast furnace repair to resolve ignition issues and failing blowers, as well as complete furnace installation tailored to the specific square footage of your residence. Our technicians ensure your system delivers steady, clean heat throughout the dampest months of the year.
Summer heatwaves in the Puget Sound have made home cooling an essential comfort during Northwest summers. We provide custom ac installation and comprehensive ac maintenance to keep your unit running efficiently during humid summer stretches. If your existing cooling system is outdated or failing to keep up with rising temperatures, we offer complete air conditioning replacement to maximize energy efficiency.
Core HVAC services include:
- Furnace repair
- Gas and electric furnace installation
- Custom home ac installation
- Seasonal ac maintenance and system tune-ups
- High-efficiency air conditioning replacement
Seattle Indoor Air Quality
Trapped Pacific Northwest moisture creates ideal conditions for dust mites, mold spores, and regional allergens inside home ductwork. Our thorough air duct cleaning services remove built-up debris, pet dander, and moisture accumulation from your ventilation system. Clearing these pathways improves overall airflow and helps your HVAC equipment run cleanly all year long.

Very happy with our service. It was easy to schedule an appointment, they arrived within the arrival window they gave us, and fixed the issue with our tankless water heater quickly. The lead person was very knowledgeable and experienced. I overheard him training the new guy with him, and was impressed at his method, asking questions for the new guy to think through and answer. This further increased my confidence in their work. I will continue to go with them for water heater maintenance and repair. Thank you!

The technician who came out was very knowledgeable and answered all my questions on our water heater and hydronic radiant heating system. He pointed out that we had the wrong mixing valve with lead on our potable water lines and replaced it with a lead-free version right away. Would highly recommend their service.

I had a new tankless water heater installed last week. Tom and one of his employees came to help with the installation. The job took about 3-4 hours to finish. They were very professional and knowledgeable.
I asked Tom couple questions regarding the water heater before and during the installations, and he answered all my questions.
I would definitely use Washington Water Heaters for a future service - 5/5!

Our 5 year old water heater stopped heating over the weekend (WWH had installed it). We waited until Monday to call as we didn't need emergency service. They got service tech Ryan out same day. It was an easy fix and he checked and adjusted the heater while he was here. Excellent service for a fair price. If you need a new water heater or service th is company is great.

This is my second or third time working with them over the past five years — they installed two air-conditioning units and two water heaters for me. Every experience has been excellent. The crew is professional, punctual, and detail-oriented. Jeremy in particular stands out- answers all my questions with utmost patience. Their ongoing maintenance support has also been very reliable. Five stars, without hesitation.

We had a problem that water in our bathrooms and kitchen was not coming hot enough and the issue was with the mixing valve. Other businesses were quoting double the amount and not guaranteeing their solution will fix the issue.
Tom was excellent. He was quick to diagnose and recommend a solution, and then proceeded to do the fix, all within about an hour. We are very happy with the results.
I’m glad I called Washington Water Heaters and I highly recommend this business to anyone looking for water heater related work.

Frequently Asked Questions
Do I need a permit for a water heater replacement in Seattle?
Yes, the Seattle Department of Construction and Inspections requires a permit for tank and tankless installations. We manage the entire permitting process on your behalf to guarantee your new equipment satisfies current city plumbing and energy codes, especially during any water heater replacement.
Should I upgrade to a tankless water heater in an older Seattle home?
Older Craftsman and Victorian homes in neighborhoods like Queen Anne or Ballard often have tight utility spaces where a wall-mounted tankless water heater unit frees up floor space. Tankless systems eliminate standby heat loss during chilly winters while delivering continuous hot water on demand.
Is a heat pump water heater worth installing in the Pacific Northwest climate?
Installing a hybrid heat pump water heater unit is one of the most effective ways to lower your home energy consumption in Western Washington. These systems draw ambient heat from the surrounding air and qualify for significant local utility rebates through Seattle City Light.
