Mike W.

Don't hire Integrity. They did not show up for service call , no one called to cancel appointment. Made service appointment seven days in advance. I waited all day for a tech to arrive, finally at 4pm I called customer service. They indicated they would not be arriving for schedule appointment and did not have time for reschedule. Very unprofessional and no consideration for people who take a day off work . I highly recommend you call anyone but Integrity for service calls.

Integrity has done an outstanding job for us in every respect. They installed a new furnace for us four years ago and performed annual servicing ever since. We were lucky to find them.

We had an extensive remodel project that involved moving both the furnace and the water heater, as well as re-ducting most of the house and crawl-space. It was a complex job and our primary consideration was that it be done well. Integrity's bid was the highest but we felt it was also the most honest and realistic. A job as complex as ours is always going to run into unanticipated situations, but Jason assured us that no matter what they ran into, they would stick to the original bid. We were planning to have all this work done during the summer months, but as luck would have it our old furnace bit the dust early and we wound up having this done during the Great Freeze and Blizzard of February 2019. The crew was fantastic, doing stellar work in harsh conditions, putting in long hours to get our heat restored. The were always friendly, polite, and in good spirits. We are now warm and toasty, heat is even throughout the house, everything is working great. There was a minor glitch a couple of weeks after the job was complete (a faulty safety switch), and it got fixed the same day we called it in. Our thanks to Jason and the crew for a job well done: Billy, Cory, Scott, Josiah, and Desmond. We highly recommend Integrity Energy Systems, you won't be sorry. RB & SC Tukwila

The folks at Integrity Energy Systems did an excellent job with our complete HVAC replacement. The work included all permits, the needed electrical panel upgrade, the removal and disposal of our existing oil furnace, and the installation of a Trane heat pump and air handler/furnace for heating/ cooling, as well as whole house air purification via Air Scrubber Plus. Throughout the entire process everyone we worked with was helpful, professional, candid, knowledgeable, courteous, friendly, and never pushy. Matt worked diligently to listen to our needs, offer advice, and then put together the three comparative bids we needed to choose the best system for us. In addition, we happily found the pricing from Integrity very reasonable. The attention to detail throughout the entire bidding, preparation for install, and installation process was excellent. Integrity came out ahead of the installation and met with us to understand our specific concerns, needs, and expectations for the install. Even though our installation was done during an extremely busy time for the company, Integrity was able to bring in extra staff when needed and/or have folks stay late to complete work to keep things moving. They did everything possible to get the system correctly installed on schedule and to get us up and running as quickly as possible. In addition, Integrity worked with us during the install to locate system piping, electrical lines, etc. where they would work best for us, even though this at times required extra effort on their part. We’ve been using our system for well over a month now and we are extremely pleased.

It went as good as it could possibly go. The call for an estimate was answered within 24hours. The customer service people were able to keep tabs on where we were at in any previous conversation. The estimate for the HRV installation was free (big plus!). Other HRV estimates came with a few to just cost out the installation. The estimate was in line with another competitive bid. The service was booked for two weeks away and the day of service went incredibly smooth. All interactions with the installers were courteous and they took their time to talk us through what was going to happen. Overall, this company went above and beyond and we are thrilled to have worked with them.

They completed their work and I'm happy with it. What is hard for me is the city of Bothell has been a big hold up and it just took an unreasonable amount of time it really threw off their schedule and completion dates. But that really wasn't their fault. I would use them again.

Description of Work
Installed 2 heat pumps, 2 furnaces, 8 thermostats, 7 control sensors for each zone. Installed for a church.

I didn't have a gas line to my stove. I put a gas stove in and so Integrity ran the gas line to the stove. I probably could have had someone do it for a little cheaper, but trust is a big deal. For the quality of their work, I'd say A-plus. They're awesome. Another thing I liked about them is they're on top of things. I would definitely be likely to use them again.

The new air conditioning and heating unit was the first thing I had done to my house when I moved in. It was very expensive. I would grade them all A's. I think they might be a little more expensive, but they do a really good job. When I moved in in August last year, I had moved from a house that had air conditioning into a house that didn't and it was awful. I made some calls and another place, a good company, they recommended Integrity. This place was booked, and so Integrity came out. It took about a week, but within a week I had air conditioning installed and so that was a big deal. Even the price, the air conditioning, I would give everything an A-plus. I came in when they were really busy, I mean super busy, and they managed to take care of me, so that was a big deal. Probably they'd be the only one I'd use in the future if necessary.

Installation went fine. Love the new furnace . You really want to listen to Matt the estimator about heater sizing, I wanted bigger but he explained to me why bigger isn't always better. The size he suggested works perfectly for our size house even though bigger would have cost more he didn't try to up sell me . I felt the price was very good also.
