Best Heating & Air Conditioning / HVAC In Mukilteo

“Updated for 2025: Legacy One once again came through for us when our heat pump went out during the hot streak in July. They quickly diagnosed the issue, got us on the calendar ASAP, and provided great installation and service installing a new, must more efficient heat pump. The difference is amazing - we have been able to keep the house at a call 75 degrees on the 90 degree days with only the heat pump. Highly recommend again!

Legacy One Heating has been our go-to company for our home heating and cooling because they are reliable, offer helpful advice and provide cost-effective solutions.  We called them the first time when our water heater died unexpectedly. Karl, the owner, responded immediately, giving us options and ultimately saving us thousands of dollars on the replacement.  We used them again to install a new heat pump system.  We now are able to keep our house warm and cool for a fraction of the cost. We even leveraged their services to clean and update an existing fireplace.  They added a programmable thermostat and breathed new life into the old system so we didn't have to purchase a replacement. The entire team was courteous, efficient, on time, and able to deliver on their estimates!  Thanks so much for your help.“

“Zachary Conrad at BelRed did a great job servicing my heat pump. He was very efficient, effective, and his customer service was top notch. Definitely recommend!“

“The All Points team installed 2 mini split units in my condo. This involved some problem solving because of HOA regs which were handled expertly. An issue with the electrical sub contractor was handled perfectly by AllPoints to my satisfaction. I can recommend them fully and without hesitation.“

“Michelle was wonderful! Did a complete service and added new labels. She was here right on time. Very helpful and skilled woman>. Thank you!“
