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!

Federal Way homes, especially the older ones near the coast, tend to collect salt, pollen, and mold inside ductwork. When that buildup restricts airflow, comfort drops and energy costs rise. Lots of homeowners don’t realize this, allowing their ducts to slowly worsen, impacting their home’s energy efficiency, air quality, and more.
We provide deep-cleaning and air-sealing services to restore your duct system’s performance and improve indoor air circulation.
Our Air Duct Services Include:
• Brushing & negative-pressure vacuum cleaning
• Duct leak testing & sealing
• Insulation upgrades
• Layout adjustments for better balance
Building America Program (U.S. DOE) research shows that well-sealed ducts can reduce HVAC energy use by up to 25% and improve airflow to rooms that previously ran cold.
Federal Way’s coastal humidity and long vent runs in two-story homes make dryer maintenance extra important. Lint buildup restricts airflow and makes dryers overheat, wasting energy and increasing wear on your appliance.
Our vent cleaning services use rotary brush and high-suction equipment to fully clear vent lines - even those that run through attics or across long spans.
Dryer Vent Services Include:
• Complete vent cleaning & brushing
• Reconfiguration or rerouting
• Vent repair or cap replacement
• Airflow testing
Energy Department Fact: A clean dryer vent improves drying efficiency by up to 30%, saving both time and electricity.
Local Note: Federal Way’s many multi-family homes and townhomes often share vent ducts or have long, twisting runs - a setup we specialize in servicing safely.
Federal Way’s proximity to I-5 and industrial corridors means fine particulates and vehicle emissions often affect indoor environments - even when windows are closed. Proper ventilation and air purification make a major difference.
We install modern IAQ solutions to help you breathe cleaner, fresher air year-round:
• Whole-home filtration systems
• UV-C purifiers for bacteria & mold
• HRV/ERV systems for balanced air exchange
• Humidity control and dehumidifiers
University of Washington researchers found that improved ventilation and filtration in Puget Sound homes can reduce PM2.5 exposure by over 70%, improving respiratory health during smoke or pollution events. This is really important for protecting your family’s health! With the increased amount of wildfire smoke, indoor air quality has really seen a big hit.
Local Insight: Federal Way’s tree canopy and marine air mean pollen and moisture levels shift fast - we tune systems to adjust automatically with outdoor changes, so all you have to worry about is what temperature you want your home at.
