Tucked in the foothills of the Cascades, Maple Valley is one of our favorite towns in the area! Whether you live in Ravensdale, Lake Wilderness, or in one of the newer subdivisions off SR 169, we’ve likely done work nearby and are very well-versed in the needs of the homes and businesses in the area.

As a local company serving the Puget Sound area, we understand what it takes to keep your home comfortable year-round.
We’re not outsiders - we live and work in the area. That gives us insight into local challenges, such as:

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!

With heavy forests and seasonal pollen bursts, Maple Valley’s ducts see extra stress from organic debris and mold. Ensuring ducts are clean, sealed, and protected is critical.
We provide:
• Deep cleaning (rotary brush, negative pressure)
• Duct sealing & insulation
• Replacement & reconfiguration
• Moisture barrier installations
According to climate data, Maple Valley receives approximately 40 inches of rainfall annually, higher than many nearby lowland areas, which means moisture control and system design matter more than ever. Thankfully, we’ve got the know-how and experience to accurately give you recommendations and then get the job done right - the first time!
Maple Valley’s wind and tree debris can clog exterior vent hoods, reducing airflow and increasing fire risk.
Our services include:
• Lint removal with high-powered brushing
• Vent rerouting for better layout
• Exterior hood maintenance (debris clearing)
• Safety inspections & airflow testing
Fire Safety Fact: Every year, thousands of house fires occur specifically because of dryer vents, costing lives and homes. Maintaining them is very important, and we’re glad to offer it to give you peace of mind, as well as efficient clothes drying!
Local Insight: Detached garages or workshop laundry areas are common in Maple Valley; such long, multi-directional vent runs require care and periodic maintenance.
Maple Valley’s wooded environment, combined with tight contemporary homes, creates a buildup of volatile organic compounds (VOCs) and moisture. That’s why solid ventilation and purification matter. Our team will come to your property, assess your current HVAC system and what needs you might have, and then offer our recommendations on next steps, so you’re fully educated throughout the entire process. Then we’ll get everything installed to provide you and your loved ones with cleaner air!
IAQ Services Include:
• UV-C air purifiers
• Multi-stage filtration (HEPA, activated carbon)
• HRV/ERV ventilation systems
• Dehumidifiers / humidity control
Fun Fact: In Washington State’s Department of Ecology assessment, indoor particulate matter (PM².⁵) from wildfire smoke can accumulate indoors and raise exposure levels by 150–300% without proper filtration and ventilation. In recent years, our region has seen significant amounts of unhealthy indoor air due to wildfire smoke.
Local Tip: Many homes in Maple Valley feature fireplaces or wood stoves - combining these with ventilation systems keeps indoor particulate levels lower and your health better.
