  Thoroughly impressed and so glad we went with Glendale Heating & Air — professional, capable, and efficient with the best customer experience so far. (Will update post install) I have been working with Debra to coordinate our furnace update (30+ yrs old Lennox originally installed by Glendale and running great!) and heat pump install… as well as additional air return, air quality monitor and custom filtering solution. She has been extremely responsive, professional and efficient with my time, needs and budget. All other on-site quotes I got took 2-3 hours of my time with a pressure to commit to a $17-30k purchase and disastrous follow-ups (even from “A” rated companies)… while Debra was knowledge, provided great advice, was in and out in under 30 minutes and emailed me a detailed estimate the next day! I just wish all businesses could be so professional, personable, efficient and cost effective as Glendale! It’s the professional & hustle service I learned in my youth in construction with my father, still do today, and appreciate from others.

  Glendale Heating was just great!  Our 50+ year-old gas furnace finally bit the dust and left us with no heat in January.  Glendale responded quickly with a reasonable estimate.  No up-selling, no issues.  A replacement furnace needed.  Luckily the weather cooperated and space heaters kept us comfortable until the installation team came.  They were very efficient, making their way through our messy, unfinished basement in our 100+ year old house.  They arrived at 9am and our new furnace was up and running at 4pm when they left.  It's been about a month ago now and everything works perfectly.  I just can't say enough good things about Glendale Heating.  Fair price. Pleasant, happy, professional installers doing great work.

  We purchased our home in Kent back in 2019 and really wanted to have AC installed after the large heat waves that hit Washington the last few summers. We got 3 quotes and Glendale was priced right in the middle of their competitors and seemed very knowledgeable when giving the quote. They were also the company listed on my furnace, and that has been running like a champ for 23 years so figure they do good work! And since they were already doing the AC, I asked them to replace the furnace anyways just since it was getting old and they were already here. I was not disappointed. Riley and Ray did great clean work on the two day job. They communicated every step of the way and asked questions on my preferences. They were by the books, pulling needed permits, etc to do the job right. I highly recommend Glendale heating!
