Outstanding Customer Service

"Please let Matt know that I really appreciate his customer service and how he handled this transaction, very professionally each time I had contacted him. He stated that Brennan Heating is a good company to work for. I have already told a few people about Brennan Heating…These days you never really know what kind of customer service you’ll get even with a high rating although my friend is right. Thank you very much for having outstanding customer service!"

Professional Manner & Immaculate House

"My husband and I met the Brennan crew when they first helped to install our furnace in our past home. Their professional manner in the installation of that furnace was evident. The house was immaculate when they left and they all continued to provide us support as we needed it. We were so impressed with your work that we decided to bring you back to install a gas insert in our family room. That room was transformed from an unusable space to a warm and inviting area."

-M. & A. Nouwens, Shoreline

Professional Service

"I just wanted to say thanks for the professional service.

Wonderful Experience

Crew Went the Extra Mile

"Two of your technicians recently spent two days in our home installing a new gas boiler to warm our very chilly house. They were efficient, friendly, and did a great job cleaning up afterwards. The two hard-working guys also kindly installed a new light in our shadowy furnace "nook" so we can now actually see our sparkling new boiler. In an era when good service is hard to find, my husband and I just thought you should know these two gentlemen went the extra mile for us."

-Penny LeGate, Seattle

What a relief!

"77 degrees and dropping. Words cannot describe the joy and relief of cool indoor air! What a great crew - professional and friendly - excellent work (that was a lot of work) - answered all our questions (patient too :)) Thank you so much for helping us choose the best equipment for us - we are very satisfied already - can't wait to use our new furnace. P.S. Will refer business to you!"

-Greg and Cindy

Very informative and understanding

"I had Brennan put in a new energy efficient furnace. The rep (Ryan) that provided the estimate was very informative and provided furnace options, understanding that I wasn't quite ready to have the work done. 7 months later I called him back, he was able to honor the original estimate and scheduled the work within two weeks. The installers were very informative, the lead technician was very experienced and knowledgeable. He worked with me to determine the best way to install the intake & exhaust pipe. The pricing was competitive."
