Seattle has always had the rainy city reputation, and for good reason - but now in recent years it’s also been hitting hot weather records. This wide range in temperatures means that homes and businesses are usually dealing with fluctuating levels of air quality and various needs for their HVAC systems. These unique HVAC and indoor air quality challenges are well understood by the professionals at NW Energy Conservation. We bring trusted heating, cooling, duct, ventilation, and indoor air solutions to homeowners and businesses across Seattle, Bellevue, Capitol Hill, West Seattle, and the surrounding Puget Sound region.
Whether your furnace sputters in Ballard, your ducts leak in Queen Anne, or wildfire smoke creeps inside your Rainier Valley home, we’re here to provide expert service, clear communication, and long-term solutions for your HVAC needs.
Seattle’s mild, wet climate and high humidity mean HVAC systems face extra strain. Coils can get coated in grime, outdoor units corrode faster, and short heating or cooling seasons lead to intermittent cycling.
Recent summers have also pushed Seattle into more frequent heat waves - so much so that the city is no longer the “least air conditioned” U.S. city. That title is now held by San Francisco! That means more homes are relying on AC and mini-splits to stay comfortable during our hot (but beautiful) summer days.
Plus, air quality in Seattle is becoming a growing concern: The Puget Sound Clean Air Agency stresses that outdoor pollution influences indoor air quality, especially during wildfire smoke events. Their organization and King County warns that indoor pollutants can easily exceed outdoor levels, by 2–5× in some cases.
Because we live here, we know exactly how to design and build HVAC systems that address Seattle’s humidity, rain, smoke, and housing styles - from Craftsman to modern condos, from offices to restaurants.
The work was completed at a very professional level. Everything was done neatly: the indoor unit was installed evenly, the ductwork was well insulated, and the outdoor unit was mounted securely and looks very tidy. After the installation, everything was cleaned up, which was a pleasant surprise. The system runs quietly and efficiently, and it’s clear that the technicians know their job well. I definitely recommend this company to anyone looking for quality installation and responsible service.
They always do a good job for a good price. Highly recommended.
NW Energy Conservation did an Awesome job! Great communication and really great to work with! Highly recommended!
This is the company who cares about customer, they did few jobs for me and I am always satisfied with their professionalism and creativity. Recommending for all!
I had our AC go down on hot day, we called Alex and they came out and saved the day. Great service and value.
Alex and his crew helped us with installing new Mitsubishi heat pump. We went with most efficient system and stayed within budget. Would recommend to friends and family for all hvac needs.
Once Aleks and crew started working on my system it's been a game changer. I even got a new unit installed from them and it's the best one in the house. It took them a few visits to fully diagnose as they didn't do the initial system install but they're super quick to respond and were easy to schedule with. They've completely overhauled a crappy install job from another company and my AC is much stronger and colder than before. He might not be the cheapest in town but the quality is much better than average and he charges what it needs to cost to do a good job and is quick to adjust anything afterwards if needed. Thank you!
Alex told me everything I needed to know about furnaces, what my options were, and that he could install a new unit that very day! I had to wait one day to get the estimate paperwork from both companies before I made the decision. Alex quoted me $400 less than the scary guy and had the unit installed the day after I called him. The tenant is happy, the furnace is great, and I saved a ton of money. Alex answered all my questions, was very responsive, and his employees were professional and helpful. Highly recommend!
When winters in Seattle bring soggy cold and a drizzling rain that never ends, you need heating you can count on - without overpaying on energy. We provide furnace and heat pump services tailored for Seattle homes:

• Heat pump systems (dual heating + cooling)
• Ductless mini-split heating for rooms without ducts (ideal for older homes)

Seattle is seeing more days above 80°F. As a result, we’ve been installing a lot more AC units than in past years. In fact, Seattle homes with Air Conditioning went from 31% to over 50% in recent years. As heat waves become more common, having reliable cooling is no longer optional. If you’ve gone through a heat wave with nothing more than a fan and an iced drink, you know how important it is to have reliable comfort around the clock. Fortunately, we offer professional services in installing AC units, repairing AC units, and also maintaining them to prevent breakdowns in their much needed moments.
NW Energy Conservation offers these HVAC services:
• Air conditioner installs & repairs
• Ductless mini-split systems, typically for retrofitted spaces or older homes
• Heat pump cooling (dual use for AC and heat)
For Seattle homes with limited duct space — think row houses, older homes, or additions — ductless systems are smart, efficient solutions.
Lint fires are one of the most preventable home hazards. The NFPA reports 16,000 house fires yearly linked to dryers. That is a huge number for something that is completely avoidable. Fortunately, our professional team is well-versed in this field and can help you today.
Our Seattle dryer vent services include:
• Deep lint cleaning
• Vent repair or replacement
• Reconfiguration for longer duct runs to make sure they’re safer and code-compliant

Given Seattle’s damp climate and compact urban layouts, vents often route long distances or through tight spaces - making regular cleaning critical.
Seattle’s air is often considered clean, but indoor air tells a different story. According to the Washington State Dept. of Health, indoor pollutants can rise significantly, especially when ventilation is poor.Seattle also frequently experiences pollution from wildfire smoke during the summer.
