Customers frequently highlight responsive scheduling, courteous technicians, and thorough repairs. Reviews note clear explanations of options and reliable follow-up after service visits.

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!

We had a great experience with Glendale Heating & Air Conditioning. Our furnace wasn’t working and the house was freezing, but Sergei came out and did a fantastic job. He was professional, knowledgeable, and took the time to set everything up properly. He made sure the furnace was running efficiently and that we were warm again before he left. No more glam camping!

We really appreciated Sergei’s attention to detail and clear explanations. Highly recommend Glendale Heating & Air Conditioning, and especially Sergei, for reliable and honest service. See you next year!

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!
