Often, when running the heat over the past year , we have smelled oil in the house. We recently had a very strong smell of oil in the basement. Greg came out and was meticulous in searching for a solution. He found a blackened nozzle that needed replacement and did so quickly, charging us a fair price. Several days later, and no hint of the oil smell. Greg is s patient and very knowledgeable - highly recommended!
Great company! Worked with them for years on an old oil furnace we had and then just recently had them replace that furnace with a new heat pump. Great communication, price, personality and install speed. Very professional install, amazing sheet metal work.
Glendale was great to work with from the recommendation from my oil company to call them, when I needed a new oil furnace, to the finished install 3 days later! Bryan was knowledgeable and friendly. I am confident the Thermo Pride furnace will be great from all the reviews and recommendations it came with! Thank you to the Glendale business and staff for your great service!
Glendale’s practical approach, competitive estimate, and open lines of communication earned my business. The recommended unit works well for the size of our home, installation was completed in two days and passed inspection with flying colors. Highly recommend Glendale!
My wife and I had a new furnace, heat pump and 200 amp electrical panel installed. We had several bids but decided to go with a local family owned business instead of a corporate business which turned out to be an excellent decision. Dave Ross, our estimator, did a nice job of explaining everything that we needed and was did not try to up sell us on unnecessary products. Brian and Zeek were our installers and they were very professional and easy to work with. They did an outstanding job of installing the new equipment and worked seamlessly with Electrical Outfitters NW, who did the electrical panel and additional wiring requirements. After finishing the installation, Brian explained all the information needed to my wife and I so we felt comfortable running the new furnace and heat pump. These guys made us feel totally confident that we were getting everything we were hoping for with a sense of connection to the company's goals of taking care of the customer. We would highly recommend Glendale Heating for any of your heating and air conditioning requirements.
