Emergency Service



"Thank you for the great service you provided in advising on and installing the heat pump in our West Seattle home. Everyone we dealt with on your team was professional, knowledgeable, responsive, courteous—and patient with our many questions. Thank you!"

- Kathy Humphrey

"Hi Jason and Brandon! I wanted to thank you for coming to the rescue with my warranty issue via another company. The Trane Rep you contacted for me really helped too! I will be shouting Integrity Energy Systems IS AWESOME from this moment forward…you have definitely proven that to me! Blessing to you both. Tami :))"

- Tami Carney Zinsli

"They ordered the units that would fit into my per-existing spaces and came when the units arrived. They worked with us to install the units as the rooms were available so we did not have to have any rooms that we could not book. They did a very professional job on the installations, clean up was extraordinary, and they instructed the staff on the use and care of the units. They took the old units away so I did not have to worry about how to get the units taken care of properly. I will need 10 more units next year and will certainly call Integrity Energy Systems to do the job!"

- Cindy Hassinger, Leavenworth, WA

"These guys are the real deal. Glad I found them via Yelp! I have a furnace that was installed & serviced by Ballard Natural Gas for many years. Funny enough, the same technician who has serviced the unit now works for Integrity. They were good communicators, on time, mellow, and easy to do business with. I prefer Integrity than dealing with the BNG home office. My new HVAC company!"

"These guys have been great. At a realtor, I sometimes need contractors to give me an opinion for what work on a home might cost. Recently I needed to call on these guys twice. They came out quickly and gave me a no nonsense estimate for the work. Even when it was news my client probably wouldn’t want to hear, they didn’t sugar coat anything. I appreciate the honesty. Integrity isn’t just their name, its a business model they take seriously. You guys are officially on speed dial. Talk to you soon."

"Their name 'integrity' is no joke. These guys are not only very responsive but they really go above and beyond to satisfy the customer."

"Integrity Energy Services installed my sweet new Trane XV95 along with the Trane Clean Effects electronic filter. They showed up on time and did a great job, and for a decent price. I opted for the Northridge earthquake gas shut off valve and the Honeywell Prestige 2.0 color thermostat with remote thermostat and outside temp sensor. I have a rental apartment downstairs and my tenant now has a way to control the temperature in the house with this remote when I’m not home! This is a nice, nice setup! Brandon from Integrity came by a few days after the install to do a walk through with me to make sure I understood how everything worked, including the thermostat and filter. Everything works great, my house is warm and toasty and the air is clean! Brandon recommended the Trane Clean Effects filter, due to the fact that I have allergies…and it was so worth the extra cash! Anyway, bottom line is this…Integrity Energy Services is a young company but they have years and years of combined experience installing heating systems. They are also trained and certified at the factory by Trane. Okay, I couldn’t be happier with this system and Integrity Energy Services. The installers Josh and Jason did a great job and left no mess. My renter is very happy as well!"

"Did business with them they are good honest guys"

- Robert W. Seattle, WA 12/2/11

"Appointment was made and the service technician arrived on time. He explained the totality of the work to be done, including the gas pressure check. He thoroughly cleaned the furnace and found no adjustments were needed."

- John Siegfried

"High quality operation. Very responsive to customer needs. High desire to have everything done right and as promised with actions to back it up. They did an excellent job on a difficult installation with great followup. Customer service is outstanding. No hesitation in recommending them."

- Dale Tuvey

"Excellent work, very professional, and quick to follow up regarding any questions or concerns I had—including a site visit a few days later for a general checkup."

- Haven Ley

"My furnace was down. Jason the owner is the person to talk to you. He sent a tech out that day, a part was ordered and fixed the next day."

- Kenneth Bonnem

“I would not hesitate to recommend IES to my friends. They are conscientious, responsive, and skilled. I’m a happy customer.”
